Prediction of Radioactive Corrosion Product Transfer in Primary Systems of Japanese Prototype Fast Breeder Reactor MONJU

Youichirou Matuo, Masanori Hasegawa, Yoshiharu Maegawa, Shinya Miyahara
Proc. ASME. ICONE18, 18th International Conference on Nuclear Engineering: Volume 5, 71-78, May 17–21, 2010
Publisher: American Society of Mechanical Engineers
Paper No: ICONE18-29171

...-precipitation model. The density of each deposited CP and dose rate of primary coolant system in MONJU was estimated by using the PSYCHE and QAD-CG code. From the calculation for MONJU, it was predicted that deposition inventory of 54Mn would be about ten times more than that of 60Co in 20 years...
