Probabilistic fire analysis capabilities, applications and weak points Original Research Article

Fires occur in nuclear power plants with a relatively high frequency, and can cause multiple and simultaneous failures of redundant or diverse plant equipment or systems. The development of a method of probabilistic fire risk analysis, although subject to more uncertainties than internal events, can provide insights complementary to those provided by deterministic analysis. In many cases, it can also provide a more realistic point of view of the risk involved.
