4:20 PM - 4:35 PM

[2H14] Research and development of an innovative transmutation system of LLFP by fast reactors

(5)Thermal integrity evaluation of LLFP targets

*Hiroyasu MOCHIZUKI1, Satoshi CHIBA1 (1. Tokyo Institute of Technology)

Keywords:LLFP transmutation, fast reactor, target pin, thermal integrity, RELAP5-3D

Using RELAP5-3D, we evaluated the target integrity when various LLFPs are transmuted in a fast reactor equivalent to "Monju". The analysis model was validated with the data measured at “Monju”. The intactness of the 129I pin, which is the most thermally severe, and the integrity of the entire core are evaluated.
