Nuclear preparedness in Norway is in large based on the experiences and learning outcomes from the Chernobyl-accident of 1986, regarded as the most significant nuclear accident affecting Norway.
Nuclear and radiological events can have significant consequences, and the demand for information will be both huge and immediate. Managing of such events demand great scientific understanding, and will involve a large number of actors, across all sectors of government.
As such, there is a need to pool resources and coordinate advice and information to the decision-makers and general public. In addition, such events will require a degree of international communication and cooperation. Hence, a permanent nuclear preparedness was established in the aftermath of Chernobyl, and continues to be maintained and developed further through learning outcomes from exercises and events. Here you can read more about the nuclear preparedness organization.
Nuclear and radiological events are described as both accidents, as well as incidents stemming from malicious acts in times of peace, national insecurity, and war. In the event that an event has occurred or is likely to occur, and could have an impact on Norway or Norwegian interests, the Crisis Committee for Nuclear Preparedness will secure a coordinated effort to manage the event and provide information. In the early phase of a nuclear event the Crisis Committee has the authority to make decisions on the implementation of a number of pre-described measures.
The mandate of the Crisis Committee states that all nuclear and radiological events and incidents, no matter how probable, shall be managed. Therefore, six scenarios have been agreed to dimension the response of the Crisis committee, and provide a tool for prioritizing decisions on protective measures taken.
