Characteristics of Nuclear Power Plant Fires Involving Electrical Enclosures



Isaac Leventon, Kenneth Hamburger, Kevin B. McGrattan, Rick D. Davis


PRIMARY AUDIENCE Fire protection and fire probabilistic risk assessment engineers conducting or reviewing fire modeling that supports fire probabilistic risk assessments related to characteristics (e.g., ignition, fire growth, and peak heat release rate) of electrical enclosure fires in nuclear power plants. KEY RESEARCH QUESTION What are the characteristics (e.g., common causes, ignition mechanisms, detection type) of electrical enclosure fires; what impact does fire cause type have on the severity, duration, and damage type of electrical enclosure fires; and how does this vary for fires in electrical enclosures versus all fires in nuclear power plants? can this information be used to inform testing, fire modeling, and risk assessment of electrical enclosure fires?
