Reactor physics R and D for accelerator-based TRU transmutation

Various researches and developments are required for the realization of a minor actinide transmutation plant. This report describes the concept of a zero power experimental facility taking account of the necessary R and D items from the view point of reactor physics. A concept of a 40 MW experimental reactor is also shortly described for a possible option of constructing it in JAERI-Tokai site. The related reactor physics activities so far at JAERI are briefly reviewed. This covers integral spallation reaction experiments and intermediate energy radiation shielding experiments. (author)
