Report Title:Accidents in Nuclear Ships
Activity Acronym:RAK-2
Authors:P.L. Ølgaard
Abstract:This report starts with a discussion of the types of nuclear vessels accidents, in particular accidents which involve the nuclear propulsion systems. Next available information on 61 reported nuclear ship events is considered. Of these 6 deals with U.S. ships, 54 with USSR ships and 1 with a French ship. The ships are in dmost all cases nuclear submarines. Oniy events that involve the sinking of vessels, the nuclear propulsion plants, radiation exposures, firedexplosions, sea-water leaks into the submarines and sinking of vessels are considered. For each event a summary of avoiilable information is presented, and comments are added. In some cases the available information is not credible, and these events are neglected. This reduces the number of events to 5 U.S. events, 35 USSR/Russian twents and 1 French event. A comparison is made between the reported Soviet accidents and information available on duroped and damaged Soviet navai reactors. It seem possible to obtain good correlation between the two types of events. An analysis is made ofthe accident and estimates are made of the accident probabiiities which are found to be of the order of 10^-3 per ship reactor year It is finaily pointed out that the consequences of nuclear ship accidents are fairly local and It is emphasized that some of the information on which this report is based, may not be does in no way not approach the magnitude of the Chernobyl accident. correct. Consequently some of the results of the assessments made rnay not be correct.
