PACER is the name of the concept of getting energy (power) from thermonuclear explosions. Moir modified the concept calling it PACER Revisited. Modifications include: yield changed from 20 kt to a goal of 2 kt or so; up to 99% fusion yield based on near term technology; replacing the unlined earthen cavity with an engineered steel lined earthen cavity; replacing the water working fluid to absorb the energy with molten salt.


Peaceful nuclear explosives to make electrical energy:
PACER Revisited

A study and project called Pacer suggested exploding a 20 kton nuclear explosive in a steam filled, earth walled cavity once every three hours
to produce 1000 MWe of power. In a series of papers this idea was revisited replacing the steam filled, earth walled cavity with a steel lined
underground cavity using molten salt droplets to cushion the effects of the explosive and absorb its energy. The yield chosen was typically
2 ktons once every 20 minutes to produce the same 1000 MWe of power. If such explosives could be initiated with 20 tons [84 GJ] of fission
yield for a total of 2 ktons then the resulting power system would be 1% fission and 99% fusion.
