FIRE PROTECTION

Fire PRA

The new regulatory environment encourages increasing the use of PRA technology in all regulatory matters. EPM’s Fire Probabilistic Risk Assessment (PRA) approach consists of an integrated assessment of the acceptability of risk, defense-in-depth, and safety margins. A Fire PRA is conducted by identifying fire scenarios that may affect the safe operation of the plant (through impacts on equipment and human actions) and estimating the frequency of occurrence of those scenarios. Transition to NFPA 805 allows for the use of fire risk evaluation (Fire PRA) to evaluate the effects of fire on the ability to achieve nuclear safety performance criteria.
