Safety of fast breeder reactor; A Lecture at the Tsuruga College

Kitabata, Takuya

Authors have given lectures on "Nuclear Safety" at the Tsuruga College to educate the students to obtain knowledge to judge the safety and values of nuclear power generation as a kind of literacy since 2003. This paper describes the contents of the final lecture of the "Nuclear Safety" on the "Safety of Fast Breeder Reactors (FBRs)". The paper explains the possibility of the positive void reactivity of FBRs and re-criticality in the unprotected loss of flow (ULOF) condition. As additional issues, sodium-water reaction and sodium leakage are also described. The risk communication booklet on the "Safety of Monju" as an activity for public relations is also explained.
