Statistical Analysis of Fire in NPP and the Regulatory Requirements to Fire Safety for Pressurized Water Reactor (PWR)

Author(s)

Abstract
Nuclear power plant operation experience over the past three decades indicates that fires at NPPs may constitute a real and significant threat to nuclear safety in addition to the conventional fire hazards to life and property. Fire Hazard Analyses (FHA) and Probabilistic Fire Safety Analyses (Fire PSA), have shown that fire may be of an important contribution to fault trees leading to core damage and other major plant damage states, particularly for older nuclear power plants (NPP). Yet, realistic modelling of fire scenarios within Fire PSA is considered difficult, due to the scarcity of reliable data for fire analysis. Design deficiencies and human factors are large contributors to the events. Thus initiators, propagators and mitigates is needed to be considered. The motivation of the present work was under taken to statistical evaluation of the reported fire accidents in the period from 1990 to 2015. The present study describe the major fire accidents that have been happened in NPPs, which provides assessment of associated hazards, Economical coasts and lessons learned have also been introduced and discussed. This will help Regulatory Authority to introduce fire safety requirements capable to avoid the recurrence of similar events in future
