Abstract

We used the 2XIIB mirror fusion facility at Lawrence Livermore Laboratory (LLL) to evaluate the fire safety of state-of-the art fusion energy experiments. The primary objective of this evaluation was to ensure the parallel development of fire safety and fusion energy technology.Through fault-tree analysis, we obtained a detailed engineering description of the 2XIIB fire protection system. This information helped us establish an optimum level of fire protection for experimental fusion energy facilities as well as to evaluate the level of protection provided by various systems. Concurrently, we analyzed the fire hazard inherent in the facility using techniques that relate the probability of ignition to the flame spread and heat-release potential of construction materials, electrical and thermal insulations, and dielectric fluids. A comparison of the results of both analyses revealed that the existing fire protection system should be modified to accomodate the range of fire hazards inherent to the 2XIIB facility.
