Fire Protection System Operating Experience Review for Fusion Applications

This paper presents a review of fire protection operating experiences from selected magnetic fusion experiments and other facilities to support design decisions, safety analysis, and risk assessment work for future fusion experiments. Quantitative estimates of fire protection system failure rates and fire accident initiating event frequencies are presented. Safety concerns of spurious actuation and water leakage are discussed for fire suppression systems. This information should be useful to fusion system designers and safety analysts, such as the team working on the design of the International Thermonuclear Experimental Reactor (ITER).
