Radical Motor Works Wants to Boil the Lake, Not the Core
A public technical disclosure proposes routing shutdown decay heat through a reactor’s secondary side to an external water heat sink.
Field notes
The concept divides shutdown heat removal into primary natural circulation, a steam-driven secondary route, and lake-coupled condensation. Its reference screen uses three 40 MW trains for a 3,400 MWth AP1000-sized case, with two trains covering the cited 79.2 MW ten-minute load. The page limits the proposal to an intact-primary shutdown scenario and says it does not replace emergency core cooling, inventory makeup, containment cooling, or installed AP1000 passive systems. Further validation is identified as necessary.
