Nuclear Facility Safety Analysis. Safety analysis reports document the analysis and the potential consequences of accidents and abnormal occurrences at nuclear facilities. For those facilities which process, store, and handle plutonium and other fissile materials, nuclear criticality safety analysis is a required element of the facility safety analysis report. The process includes the identification of hazards in the facility(including nuclear criticality safety hazards), the identification and development of potential scenarios involving nuclear criticality concerns, the development of failure modes and the potential effects of the accident, and the consequences of the accident. 1, record 4, English, - nuclear%20facility%20safety%20analysis

The International Nuclear Event Scale [INES]. Level 5. Accident with off-site risk. Criteria. External release of radioactive material(in quantities radiologically equivalent to the order of hundreds to thousands of terabecquerels of iodine-131). Such a release would be likely to result in partial implementation of countermeasures covered by emergency plans to lessen the likelihood of health effects. Severe damage to the nuclear facility. This may involve severe damage to a large fraction of the core of a power reactor, a major criticality accident or a major fire or explosion releasing large quantities of radioactivity within the installation. 1, record 5, English, - %20accident%20with%20off%2Dsite%20risk

A prompt criticality accident occurred in September last year at a nuclear plant [in] Tokaimura, Japan. Three workers absorbed potentially lethal radiation doses of about 4500 to more than 20 000 milisieverts(mSv). One of them died on [the] 83rd day after the accident … Compared with other industrial accidents occurring every day over the world, and which result in about 12 000 deaths per year in the United States alone, the Tokaimura incident does not seem to have been very serious. 1, record 6, English, - prompt%20criticality%20accident

Les plus récentes données démontrent que la catastrophe de Tchernobyl a fait plusieurs dizaines de milliers de morts, et des centaines de milliers de personnes, particulièrement les enfants, sont touchés par des maladies aggravées par la radioactivité. C'est ainsi que les cancers de la thyroïde des enfants ont été multipliés par 100 dans certaines régions. Parce que ces risques sont inacceptables, [l’Association Démocratie Écologie Solidarité (ADES) a] obtenu l’arrêt du Superphénix qui, comme le réacteur de Tchernobyl, présentait la particularité de pouvoir être l'objet d'un accident de "criticité prompte" par emballement de la réaction nucléaire. 2, record 6, French, - accident%20de%20criticit%C3%A9%20prompte

Measurements shall be made at a range of pressures up to and including the positive design pressure for each part of the containment envelope.
