CHAPTER II
COMPENSATION

Article III
Undertaking

1. Compensation in respect of nuclear damage per nuclear incident shall be ensured by the following means:

(a) (i) the Installation State shall ensure the availability of 300 million SDRs or a greater amount that it may have specified to the Depositary at any time prior to the nuclear incident, or a transitional amount pursuant to sub-paragraph (ii);

(ii) a Contracting Party may establish for the maximum of 10 years from the date of the opening for signature of this Convention, a transitional amount of at least 150 million SDRs in respect of a nuclear incident occurring within that period.

(b) beyond the amount made available under sub-paragraph (a), the Contracting Parties shall make available public funds according to the formula specified in Article IV.

2. (a) Compensation for nuclear damage in accordance with paragraph 1(a) shall be distributed equitably without discrimination on the basis of nationality, domicile or residence, provided that the law of the Installation State may, subject to obligations of that State under other conventions on nuclear liability, exclude nuclear damage suffered in a non-Contracting State. 

(b) Compensation for nuclear damage in accordance with paragraph 1(b), shall, subject to Articles V and XI.1(b), be distributed equitably without discrimination on the basis of nationality, domicile or residence. 

3. If the nuclear damage to be compensated does not require the total amount under paragraph 1(b), the contributions shall be reduced proportionally.

4. The interest and costs awarded by a court in actions for compensation of nuclear damage are payable in addition to the amounts awarded pursuant to paragraphs 1(a) and (b) and shall be proportionate to the actual contributions made pursuant to paragraphs 1(a) and (b), respectively, by the operator liable, the Contracting Party in whose territory the nuclear installation of that operator is situated, and the Contracting Parties together.

Article IV 
Calculation of Contributions

1. The formula for contributions according to which the Contracting Parties shall make available the public funds referred to in Article III.1(b) shall be determined as follows:

(a) (i) the amount which shall be the product of the installed nuclear capacity of that Contracting Party multiplied by 300 SDRs per unit of installed capacity; and

(ii) the amount determined by applying the ratio between the United Nations rate of assessment for that Contracting Party as assessed for the year preceding the year in which the nuclear incident occurs, and the total of such rates for all Contracting Parties to 10% of the sum of the amounts calculated for all Contracting Parties under sub-paragraph (i).

(b) Subject to sub-paragraph (c), the contribution of each Contracting Party shall be the sum of the amounts referred to in sub-paragraphs (a)(i) and (ii), provided that States on the minimum United Nations rate of assessment with no nuclear reactors shall not be required to make contributions.

(c) The maximum contribution which may be charged per nuclear incident to any Contracting Party, other than the Installation State, pursuant to sub-paragraph (b) shall not exceed its specified percentage of the total of contributions of all Contracting Parties determined pursuant to sub-paragraph (b). 

 For a particular Contracting Party, the specified percentage shall be its UN rate of assessment expressed as a percentage plus 8 percentage points. 

 If, at the time an incident occurs, the total installed capacity represented by the Parties to this Convention is at or above a level of 625,000 units, this percentage shall be increased by one percentage point.

  It shall be increased by one additional percentage point for each increment of 75,000 units by which the capacity exceeds 625,000 units.

2. The formula is for each nuclear reactor situated in the territory of the Contracting Party, 1 unit for each MW of thermal power.  The formula shall be calculated on the basis of the thermal power of the nuclear reactors shown at the date of the nuclear incident in the list established and kept up to date in accordance with Article VIII.

3. For the purpose of calculating the contributions, a nuclear reactor shall be taken into account from that date when nuclear fuel elements have been first loaded into the nuclear reactor. 

 A nuclear reactor shall be excluded from the calculation when all fuel elements have been removed permanently from the reactor core and have been stored safely in accordance with approved procedures.

Article V
Geographical Scope

1. The funds provided for under Article III.1(b) shall apply to nuclear damage which is suffered:

(a) in the territory of a Contracting Party; or

(b) in or above maritime areas beyond the territorial sea of a Contracting Party:

(i) on board or by a ship flying the flag of a Contracting Party, or on board or by an aircraft registered in the territory of a Contracting Party, or on or by an artificial island, installation or structure under the jurisdiction of a Contracting Party; or

(ii) by a national of a Contracting Party;excluding damage suffered in or above the territorial sea of a State not Party to this Convention; or

(c) in or above the exclusive economic zone of a Contracting Party or on the continental shelf of a Contracting Party in connection with the exploitation or the exploration of the natural resources of that exclusive economic zone or continental shelf;provided that the courts of a Contracting Party have jurisdiction pursuant to Article XIII.

2. Any signatory or acceding State may, at the time of signature of or accession to this Convention or on the deposit of its instrument of ratification, declare that for the purposes of the application of paragraph 1(b)(ii), individuals or certain categories thereof, considered under its law as having their habitual residence in its territory, are assimilated to its own nationals.

3. In this article, the expression “a national of a Contracting Party” shall include a Contracting Party or any of its constituent sub-divisions, or a partnership, or any public or private body whether corporate or not established in the territory of a Contracting Party.

4. Where jurisdiction over actions concerning nuclear damage would lie with the courts of more than one Contracting Party, these Contracting Parties shall determine by agreement which Contracting Party’s courts shall have jurisdiction.

5. A judgment that is no longer subject to ordinary forms of review entered by a court of a Contracting Party having jurisdiction shall be recognized except:

(a) where the judgment was obtained by fraud;

(b) where the party against whom the judgment was pronounced was not given a fair opportunity to present his case; or

(c) where the judgment is contrary to the public policy of the Contracting Party within the territory of which recognition is sought, or is not in accord with fundamental standards of justice.

6. A judgment which is recognized under paragraph 5 shall, upon being presented for enforcement in accordance with the formalities required by the law of the Contracting Party where enforcement is sought, be enforceable as if it were a judgment of a court of that Contracting Party.  

The merits of a claim on which the judgment has been given shall not be subject to further proceedings.

7. Settlements effected in respect of the payment of compensation out of the public funds referred to in Article III.1(b) in accordance with the conditions established by national legislation shall be recognized by the other Contracting Parties.

Article XIV
Applicable Law

1. Either the Vienna Convention or the Paris Convention or the Annex to this Convention, as appropriate, shall apply to a nuclear incident to the exclusion of the others.

2. Subject to the provisions of this Convention, the Vienna Convention or the Paris Convention, as appropriate, the applicable law shall be the law of the competent court.

ANNEX

A Contracting Party which is not a Party to any of the Conventions mentioned in Article I(a) or (b) of this Convention shall ensure that its national legislation is consistent with the provisions laid down in this Annex insofar as those provisions are not directly applicable within that Contracting Party. 

 A Contracting Party having no nuclear installation on its territory is required to have only that legislation which is necessary to enable such a Party to give effect to its obligations under this Convention.

Article 1
Definitions

1. In addition to the definitions in Article I of this Convention, the following definitions apply for the purposes of this Annex:

(a) “Nuclear Fuel” means any material which is capable of producing energy by a self-sustaining chain process of nuclear fission.

(b) “Nuclear Installation” means:
provided that the Installation State may determine that several nuclear installations of one operator which are located at the same site shall be considered as a single nuclear installation.

(i) any nuclear reactor other than one with which a means of sea or air transport is equipped for use as a source of power, whether for propulsion thereof or for any other purpose;

(ii) any factory using nuclear fuel for the production of nuclear material, or any factory for the processing of nuclear material, including any factory for the re-processing of irradiated nuclear fuel; and

(iii) any facility where nuclear material is stored, other than storage incidental to the carriage of such material;

(c) “Nuclear material” means:

(i) nuclear fuel, other than natural uranium and depleted uranium, capable of producing energy by a self-sustaining chain process of nuclear fission outside a nuclear reactor, either alone or in combination with some other material; and

(ii) radioactive products or waste.

(d) “Operator”, in relation to a nuclear installation, means the person designated or recognized by the Installation State as the operator of that installation.

(e) “Radioactive products or waste” means any radioactive material produced in, or any material made radioactive by exposure to the radiation incidental to, the production or utilization of nuclear fuel,

 but does not include radioisotopes which have reached the final stage of fabrication so as to be usable for any scientific, medical, agricultural, commercial or industrial purpose.

2. An Installation State may, if the small extent of the risks involved so warrants, exclude any nuclear installation or small quantities of nuclear material from the application of this Convention, provided that:

(a) with respect to nuclear installations, criteria for such exclusion have been established by the Board of Governors of the International Atomic Energy Agency and any exclusion by an Installation State satisfies such criteria; and


(b) With respect to small quantities of nuclear material, maximum limits for the exclusion of such quantities have been established by the Board of Governors of the International Atomic Energy Agency and any exclusion by an Installation State is within such established limits.

 The criteria for the exclusion of nuclear installations and the maximum limits for the exclusion of small quantities of nuclear material shall be reviewed periodically by the Board of Governors.

Article 2
Conformity of Legislation

1. The national law of a Contracting Party is deemed to be in conformity with the provisions of Articles 3, 4, 5 and 7 if it contained on 1 January 1995 and continues to contain provisions that:

(a) provide for strict liability in the event of a nuclear incident where there is substantial nuclear damage off the site of the nuclear installation where the incident occurs;

(b) require the indemnification of any person other than the operator liable for nuclear damage to the extent that person is legally liable to provide compensation; and

(c) ensure the availability of at least 1000 million SDRs in respect of a civil nuclear power plant and at least 300 million SDRs in respect of other civil nuclear installations for such indemnification.

2. If in accordance with paragraph 1, the national law of a Contracting Party is deemed to be in conformity with the provision of Articles 3, 4, 5 and 7, then that Party:

(a) may apply a definition of nuclear damage that covers loss or damage set forth in Article 1(f) of this Convention and any other loss or damage to the extent that the loss or damage arises out of or results from the radioactive properties, or a combination of radioactive properties with toxic, explosive or other hazardous properties of nuclear fuel or radioactive products or waste in, or of nuclear material coming from, originating in, or sent to, a nuclear installation; or other ionizing radiation emitted by any source of radiation inside a nuclear installation provided that such application does not affect the undertaking by that Contracting Party pursuant to Article III of this Convention; and

(b) may apply the definition of nuclear installation in paragraph 3 of this Article to the exclusion of the definition in Article 1.1(b) of this Annex.

3. For the purpose of paragraph 2(b) of this Article, “nuclear installation” means:

(a) any civil nuclear reactor other than one with which a means of sea or air transport is equipped for use as a source of power, whether for propulsion thereof or any other purpose; and

(b) any civil facility for processing, reprocessing or storing:

(i) irradiated nuclear fuel; or
(ii) radioactive products or waste that:

(1) result from the reprocessing of irradiated nuclear fuel and contain significant amounts of fission products; or

(2) contain elements that have an atomic number greater than 92 in concentrations greater than 10 nano-curies per gram.

(c) any other civil facility for processing, reprocessing or storing nuclear material unless the Contracting Party determines the small extent of the risks involved with such an installation warrants the exclusion of such a facility from this definition.

4. Where that national law of a Contracting Party which is in compliance with paragraph 1 of this Article does not apply to a nuclear incident which occurs outside the territory of that Contracting Party, but over which the courts of that Contracting Party have jurisdiction pursuant to Article XIII of this Convention, Articles 3 to 11 of the Annex shall apply and prevail over any inconsistent provisions of the applicable national law.

Article 3
Operator Liability

1. The operator of a nuclear installation shall be liable for nuclear damage upon proof that such damage has been caused by a nuclear incident:

provided that, if nuclear damage is caused by a nuclear incident occurring in a nuclear installation and involving nuclear material stored therein incidentally to the carriage of such material, the provisions of sub-paragraph (a) shall not apply where another operator or person is solely liable pursuant to sub-paragraph (b) or (c).

(a) in that nuclear installation; or

(b) involving nuclear material coming from or originating in that nuclear installation, and occurring:

(i) before liability with regard to nuclear incidents involving the nuclear material has been assumed, pursuant to the express terms of a contract in writing, by the operator of another nuclear installation;

(ii) in the absence of such express terms, before the operator of another nuclear installation has taken charge of the nuclear material; or

(iii) where the nuclear material is intended to be used in a nuclear reactor with which a means of transport is equipped for use as a source of power, whether for propulsion thereof or for any other purpose, before the person duly authorized to operate such reactor has taken charge of the nuclear material; but

(iv) where the nuclear material has been sent to a person within the territory of a non-Contracting State, before it has been unloaded from the means of transport by which it has arrived in the territory of that non-Contracting State;

(c) involving nuclear material sent to that nuclear installation, and occurring:

(i) after liability with regard to nuclear incidents involving the nuclear material has been assumed by the operator pursuant to the express terms of a contract in writing, from the operator of another nuclear installation;

(ii) in the absence of such express terms, after the operator has taken charge of the nuclear material; or

(iii) after the operator has taken charge of the nuclear material from a person operating a nuclear reactor with which a means of transport is equipped for use as a source of power, whether for propulsion thereof or for any other purpose; but

(iv) where the nuclear material has, with the written consent of the operator, been sent from a person within the territory of a non-Contracting State, only after it has been loaded on the means of transport by which it is to be carried from the territory of that State;

2. The Installation State may provide by legislation that, in accordance with such terms as may be specified in that legislation, a carrier of nuclear material or a person handling radioactive waste may, at such carrier or such person’s request and with the consent of the operator concerned, be designated or recognized as operator in the place of that operator in respect of such nuclear material or radioactive waste respectively.

  In this case such carrier or such person shall be considered, for all the purposes of this Convention, as an operator of a nuclear installation situated within the territory of that State.

3. The liability of the operator for nuclear damage shall be absolute.

4. Whenever both nuclear damage and damage other than nuclear damage have been caused by a nuclear incident or jointly by a nuclear incident and one or more other occurrences, such other damage shall, to the extent that it is not reasonably separable from the nuclear damage, be deemed to be nuclear damage caused by that nuclear incident. 

 Where, however, damage is caused jointly by a nuclear incident covered by the provisions of this Annex and by an emission of ionizing radiation not covered by it, nothing in this Annex shall limit or otherwise affect the liability, either as regards any person suffering nuclear damage or by way of recourse or contribution, of any person who may be held liable in connection with that emission of ionizing radiation.

5. (a) No liability shall attach to an operator for nuclear damage caused by a nuclear incident directly due to an act of armed conflict, hostilities, civil war or insurrection.

(b) Except insofar as the law of the Installation State may provide to the contrary, the ‘operator shall not be liable for nuclear damage caused by a nuclear incident caused directly due to a grave natural disaster of an exceptional character.

6. National law may relieve an operator wholly or partly from the obligation to pay compensation for nuclear damage suffered by a person if the operator proves the nuclear damage resulted wholly or partly from the gross negligence of that person or an act or omission of that person done with the intent to cause damage.

7. The operator shall not be liable for nuclear damage:

(a) to the nuclear installation itself and any other nuclear installation, including a nuclear installation under construction, on the site where that installation is located; and

(b) to any property on that same site which is used or to be used in connection with any such installation;

(c) unless otherwise provided by national law, to the means of transport upon which the nuclear material involved was at the time of the nuclear incident.  If national law provides that the operator is liable for such damage, compensation for that damage shall not have the effect of reducing the liability of the operator in respect of other damage to an amount less than either 150 million SDRs, or any higher amount established by the legislation of a Contracting Party.

8. Nothing in this Convention shall affect the liability outside this Convention of the operator for nuclear damage for which by virtue of paragraph 7(c) he is not liable under this Convention.

9. The right to compensation for nuclear damage may be exercised only against the operator liable, provided that national law may permit a direct right of action against any supplier of funds that are made available pursuant to provisions in national law to ensure compensation through the use of funds from sources other than the operator.

10. The operator shall incur no liability for damage caused by a nuclear incident outside the provisions of national law in accordance with this Convention.

Article 4
Liability Amounts

1. Subject to Article III.1(a)(ii), the liability of the operator may be limited by the Installation State for any one nuclear incident, either:

(a) to not less than 300 million SDRs; or 

(b) to not less then 150 million SDRs provided that in excess of that amount and up to at least 300 million SDRs public funds shall be made available by that State to compensate nuclear damage.

2. Notwithstanding paragraph 1, the Installation State, having regard to the nature of the nuclear installation or the nuclear substances involved and to the likely consequences of an incident originating therefrom, may establish a lower amount of liability of the operator,

 provided that in no event shall any amount so established be less than 5 million SDRs, and provided that the Installation State ensures that public funds shall be made available up to the amount established pursuant to paragraph 1.

3. The amounts established by the Installation State of the liable operator in accordance with paragraphs 1 and 2, as well as the provisions of any legislation of a Contracting Party pursuant to Article 3.7(c) shall apply wherever the nuclear incident occurs.

Article 5 
Financial Security

1. (a) The operator shall be required to have and maintain insurance or other financial security covering his liability for nuclear damage in such amount, of such type and in such terms as the Installation State shall specify. 

 The Installation State shall ensure the payment of claims for compensation for nuclear damage which have been established against the operator by providing the necessary funds to the extent that the yield of insurance or other financial security is inadequate to satisfy such claims, but not in excess of the limit, if any, established pursuant to Article 4. 

 Where the liability of the operator is unlimited, the Installation State may establish a limit of the financial security of the operator liable provided that such limit is not lower than 300 million SDRs.  

The Installation State shall ensure the payment of claims for compensation for nuclear damage which have been established against the operator to the extent that yield of the financial security is inadequate to satisfy such claims, but not in excess of the amount of the financial security to be provided under this paragraph.

(b) Notwithstanding sub-paragraph (a), the Installation State, having regard to the nature of the nuclear installation or the nuclear substances involved and to the likely consequences of an incident originating therefrom, may establish a lower amount of financial security of the operator,

 provided that in no event shall any amount so established be less than 5 million SDRs, and provided that the Installation State ensures the payment of claims for compensation for nuclear damage which have been established against the operator by providing necessary funds to the extent that the yield of insurance or other financial security is inadequate to satisfy such claims, and up to the limit provided in sub-paragraph (a).

2. Nothing in paragraph 1 shall require a Contracting Party or any of its constituent sub-divisions to maintain insurance or other financial security to cover their liability as operators.

3. The funds provided by insurance, by other financial security or by the Installation State pursuant to paragraph 1 or Article 4.1(b) shall be exclusively available for compensation due under this Annex.

4. No insurer or other financial guarantor shall suspend or cancel the insurance or other financial security provided pursuant to paragraph 1 without giving notice in writing of at least two months to the competent public authority or, in so far as such insurance or other financial security relates to the carriage of nuclear material, during the period of the carriage in question.

Article 6
Carriage

1. With respect to a nuclear incident during carriage, the maximum amount of liability of the operator shall be governed by the national law of the Installation State.

2. A Contracting Party may subject carriage of nuclear material through its territory to the condition that the amount of liability of the operator be increased to an amount not to exceed the maximum amount of liability of the operator of a nuclear installation situated in its territory. 

3. The provisions of paragraph 2 shall not apply to:

(a) carriage by sea where, under international law, there is a right of entry in cases of urgent distress into ports of a Contracting Party or a right of innocent passage through its territory;

(b) carriage by air where, by agreement or under international law, there is a right to fly over or land on the territory of a Contracting Party.

Article 7
Liability of More Than One Operator

1. Where nuclear damage engages the liability of more than one operator, the operators involved shall, in so far as the damage attributable to each operator is not reasonably separable, be jointly and severally liable. 

 The Installation State may limit the amount of public funds made available per incident to the difference, if any, between the amounts hereby established and the amount established pursuant to Article 4.1.

2. Where a nuclear incident occurs in the course of carriage of nuclear material, either in one and the same means of transport, or, in the case of storage incidental to the carriage, in one and the same nuclear installation, and causes nuclear damage which engages the liability of more than one operator, the total liability shall not exceed the highest amount applicable with respect to any one of them pursuant to Article 4.

3. In neither of the cases referred to in paragraphs 1 and 2 shall the liability of any one operator exceed the amount applicable with respect to him pursuant to Article 4.

4. Subject to the provisions of paragraphs 1 to 3, where several nuclear installations of one and the same operator are involved in one nuclear incident, such operator shall be liable in respect of each nuclear installation involved up to the amount applicable with respect to him pursuant to Article 4.  

The Installation State may limit the amount of public funds made available as provided for in paragraph 1.

Article 8
Compensation Under National Law

1. For purposes of this Convention, the amount of compensation shall be determined without regard to any interest or costs awarded in a proceeding for compensation of nuclear damage.

2. Compensation for damage suffered outside the Installation State shall be provided in a form freely transferable among Contracting Parties.

3. Where provisions of national or public health insurance, social insurance, social security, workmen’s compensation or occupational disease compensation systems include compensation for nuclear damage, rights of beneficiaries of such systems and rights of recourse by virtue of such systems shall be determined by the national law of the Contracting Party in which such systems have been established or by the regulations of the intergovernmental organization which has established such systems.

Article 9
Period of Extinction

1. Rights of compensation under this Convention shall be extinguished if an action is not brought within ten years from the date of the nuclear incident.  

If, however, under the law of the Installation State the liability of the operator is covered by insurance or other financial security or by State funds for a period longer than ten years, the law of the competent court may provide that rights of compensation against the operator shall only be extinguished after a period which may be longer than ten years, but shall not be longer than the period for which his liability is so covered under the law of the Installation State.

2. Where nuclear damage is caused by a nuclear incident involving nuclear material which at the time of the nuclear incident was stolen, lost, jettisoned or abandoned, the period established pursuant to paragraph 1 shall be computed from the date of that nuclear incident, 

but the period shall in no case, subject to legislation pursuant to paragraph 1, exceed a period of twenty years from the date of the theft, loss, jettison or abandonment.

3. The law of the competent court may establish a period of extinction or prescription of not less than three years from the date on which the person suffering nuclear damage had knowledge or should have had knowledge of the damage and of the operator liable for the damage,

 provided that the period established pursuant to paragraphs 1 and 2 shall not be exceeded.

4. If the national law of a Contracting Party provides for a period of extinction or prescription greater than ten years from the date of a nuclear incident, it shall contain provisions for the equitable and timely satisfaction of claims for loss of life or personal injury filed within ten years from the date of the nuclear incident.

Article 10
Right of Recourse

 National law may provide that the operator shall have a right of recourse only:

(a) if this is expressly provided for by a contract in writing; or

(b) if the nuclear incident results from an act or omission done with intent to cause damage, against the individual who has acted or omitted to act with such intent.

Article 11
Applicable Law

 Subject to the provisions of this Convention, the nature, form, extent and equitable distribution of compensation for nuclear damage caused by a nuclear incident shall be governed by the law of the competent court.
