Description
To enhance the inherent safety of the fast breeder reactor (FBR), unique attempts are being made in reactivity control systems design to achieve maintenance-free and reliable performance. The design proposed is the lithium injection module (LIM) for inherent ultimate shutdown. Reactor physics calculation revealed the reactivity worth of LIM in a 60 MWe metal-fueled FBR and a 1,000 MWe mixed-oxide-fueled FBR. An experimental verification on the freeze seal design assured an accurate injection temperature of LIM. Reliability, maintainability, and real time monitoring for LIM is also discussed. A definite advantage over the conventional self-actuated shutdown system (SASS) has been presented. LIM offers substantial inherent safety with improved maintainability. (author)
