Abstract

In some accident scenarios, a nuclear reactor could be assumed to be similar to a kettle. Namely, the water inside the core, or in this case in the kettle, is experiencing heating, and at some point, for a non-boiling reactor, the safety boundary may be crossed. This paper presents two approaches, i.e., statistic and deterministic, to evaluate the time it takes to boil water in a kettle as an analogy to evaluate safety criteria for a nuclear core. The two computational approaches are compared with correspondence to the uncertainty and safety margins. The performed analysis relies on the methodology proposed by the International Atomic Energy Agency technical documents, which address the essential issues to evaluate the uncertainty within a particular task. Finally, this paper assesses the safety margin criteria definition and its value in safety analysis for nuclear reactors.
