Role of condensation in aerosol source term for liquid-metal fast breeder reactor containments
Description
During a hypothetical core-disruptive accident (HCDA) in a liquid-metal fast breeder reactor (LMFBR), a considerable amount of radioactive material could be released in an aerosol form within the containment vessel. The role of condensation in influencing the source term in the cover-gas region of a liquid-metal fast breeder reactor was analyzed. A computer program was developed that considers both coagulation and condensation to solve the integro-differential equation governing the aerosol behavior in the cover-gas region. Results presented in this paper for a representative case show that condensation can have a very substantial effect on the particle size distribution in the cover gas and hence on the source term in the containment aerosol behavior computer programs. 14 refs
