Liability in the event of radiological accidents

This new assignment has been prompted by amendments to the Paris and Brussels Conventions, which regulate liability in the event of radiological accidents. To fulfil the requirements of the conventions, a new law and regulation entered into force on 1 January 2022.

Radiological damage resulting from an accident

A radiological accident refers to an event that causes damage as a result of ionising radiation from a nuclear facility or as a result of radioactive properties in nuclear material or nuclear waste. The meaning of radiological damage, as regulated by the Act (2010:950) on liability and compensation for radiological accidents, is defined as:

• personal injury or property damage,
• financial loss that is a direct consequence of personal injury or property damage,
• a loss of income not encompassed by the above but which, as a result of substantial deterioration of the environment, has been caused by damage to a financial interest that is directly linked to the environment, and
• a cost for restoring the environment or compensating for lost environmental assets, if it is a case of environmental damage that is not insignificant and the measure(s) to which the cost refers has(ve) been approved as reasonable by the authority designated by the Government.

Radiological damage also refers to a cost – following a radiological accident or in the event of severe and imminent danger of such an accident – for taking reasonable measures to prevent such damage as above and damage ensuing from such preventive measures.

Extended limitation period for personal injury claims

The amendments to the Paris and Brussels Conventions entail that the limitation period for personal injury claims has been extended, from ten years to 30 years from the time of an accident. The types of third-party liability insurance currently offered in the market only partially cover costs for claims during this limitation period.

Therefore, additional financial security is, in many cases, currently needed to cover the facility owner’s liability for delayed-onset personal injuries (more than ten years but within 30 years from the time of the accident).

Liability for radiological accidents

The Act (2010:950) on liability and compensation for radiological accidents regulates the liability of an owner of a nuclear facility (facility owner). A nuclear facility can consist of nuclear reactors and also other types of facilities that require a nuclear licence.

The facility owner has strict and unlimited liability for damages for radiological accidents. A facility owner has the primary obligation to guarantee compensation up to a certain liability amount. The liability amount varies depending on the type of facility, but it may not exceed EUR 1,200 million. Secondarily, the state shall provide funds up to this amount. When the amount does not suffice for compensation for injured parties following a radiological accident, all Convention States are obliged to provide a further EUR 300 million.

The facility owner’s liability

A facility owner shall, to the extent possible, have third-party liability insurance to cover its liability in the event of an accident that causes radiological damage. If the insurance does not fully cover the facility owner’s liability (see below) or certain types of radiological damage, additional financial security must also be pledged. This may not consist of a property on which nuclear activities are conducted and must – separately or in combination with other security – be satisfactory for its purpose.

The liability amounts for different facilities are as follows:

• EUR 1,200 million for a facility owner with a nuclear reactor in operation.
• EUR 700 million for a facility owner without a nuclear reactor in operation.

Facility owners that do not have a nuclear reactor in operation can apply to the Swedish Radiation Safety Authority for a lower liability amount. This amount may be no less than EUR 70 million for facilities and EUR 80 million for transport. The Debt Office shall be given the possibility to comment on such an application prior to the Swedish Radiation Safety Authority issuing its opinion to the Government. Decisions on any lower amount are made by the Government.

The liability amounts for facilities that facility owners must cover with insurance or other security are listed in Table 1.

Facility owners must notify the Debt Office of third-party liability insurance and other forms of security, which the Debt Office will then submit along with a statement of its opinion to the Government for assessment of whether the financial security is sufficient.

Financial security for transport

Liability for claims ensuing from a radiological accident during transport may be covered by special insurance. In the same way as for facilities, insurance concerning transport must be supplemented with other financial security if the insurance does not suffice or does not cover all types of damage. Financial security relating to a single transport must be reported to the Debt Office no later than one month prior to the start of such transport. The Debt Office assesses insurance and additional financial security concerning transport.

The liability amounts for transport that facility owners must cover with insurance or other financial security are listed in Table 2.
