Please use the SPENT FUEL POOL STORAGE 38 3 SPENT FUEL POOL STORAGE This chapter addresses the first charge of the committee's statement of task to assess "potential safety and security risks of spent nuclear fuel presently stored in cooling pools at commercial reactor sites."1 As noted in Chapter 1, storage of spent fuel in pools at commercial reactor sites has three primary objectives: • Cool the fuel to prevent heat-up to high temperatures from radioactive decay. • Shield workers and the public from the radiation emitted by radioactive decay in the spent fuel and provide a barrier for any releases of radioactivity.

Beginning with the cladding rupture, these events would result in the release of radioactive fission gases and some of the fuel's radioactive material in the form of aerosols into the building that houses the spent fuel pool and possibly into the environment. If the heat from one burning assembly is not dissipated, the fire could spread to other spent fuel assemblies in the pool, producing a propagating zirconium cladding fire.
