asteroza + energy + pebble   2

Combining a pebble thermal energy store for thermal energy recovery with tunneled underground air cavities for CAES. Possible boost of the thermal store with CPV or CSP systems. Maybe using vertically bored tunnels as well? Are they stuffing the air cavities with pebbles for thermal storage too?

Per Peterson on Pebble Bed Reactors Status
PB-AHTR, an evolutionary step for the PBMR, using liquid fluoride coolant rather than a PBMR/VHTR helium coolant. Though it ends up running through a heat exchanger into a helium brayton circuit for the turbines. If you're using a secondary circuit, why not move up to a supercritical CO2 turbine plant instead (maybe there is a radioactivity or reactivity issues between the liquid fluoride primary loop and CO2 secondary loop?

This would help to demonstrate a lot of tech for a LFTR setup though
