Hyperion Mini Nuclear Reactor Set to Transform Power Generation

SAFETY CHARACTERISTICS OF THE INTEGRAL FAST REACTOR CONCEPT

Response to Transient Undercooling Accidents

Prevention of core damage in undercooling accidents in LMRs can be provided by passive means if specific features are included in the design. The goal in the IFR is to provide a reactor response that will adjust the reactor power to the available heat rejection capability and to limit the coolant temperature increase if reactor flow is reduced.

Lots of information is in there. Most readily information available is for the IFR, PRISM or LMFBR so I couldn't find information in Lead Fast Reactors. I would expect that lead would be better than sodium since it has a higher boiling point...


Thanks.
