Contrastive study on licensing accident analysis of nuclear power plants and nuclear ships

Generally, a safety license system for nuclear facilities is implemented by governments. According to the requirements of nuclear safety regulations, accident analysis should be developed to demonstrate the safety of nuclear power plants by the operating organization during the licensing process. Similarly, accident analysis is also necessary for nuclear ships to be certificated by the shipping classification society and attain licenses from the nuclear safety authority before construction and operation. The scope and contents of accident analysis of both nuclear power plants and nuclear ships are studied and comparisons in major issues are summarized. Relevant results can be referenced in the development of licensing accident analysis and rulemaking for the upcoming floating nuclear power plant. (authors)
