BEATRIX-2 Program third annual report, January 1990--December 1990

The BEATRIX-2 experiment is an International Energy Agency (IEA) sponsored collaborative experiment between Japan, Canada, and the United States. The purpose of the experiment is to evaluate the performance of ceramic solid breeder materials in a fast neutron environment. To do this, an in-situ tritium recovery experiment is being conducted in the Fast Flux Test Facility (FFTF), located on the Hanford site near Richland, Washington, and operated by Westinghouse Hanford Company (WHC). The Pacific Northwest Laboratory (PNL), Richland, Washington, together with the Japan Atomic Energy Research Institute (JAERI) and Atomic Energy of Canada Limited (AECL) are responsible for conducting the experiment. This work is divided into two phases: Phase 1 was irradiated from January 1990 until March 1991 in Cycle 11 of FFTF, while Phase 2 will be irradiated in Cycle 12, which began in June 1991 and is scheduled to continue until approximately October of 1991 for 300 effective full power days (EFPD)
