15-18 g/cm^3 solid fuel pellets fissioning to ~8 g/cm^3 products plus trapped helium (alpha decay) will swell starting around a couple percent burn. Get them out! Stupid. Fuel recycle should separate a clean beta-decay stream from alpha-decay and transuranics. Beta goes into modest term storage plus heat dump. Transuranics contaminated with beta (lots of gamma to discourage theft) go back in as fuel. We separate and store the opppsite way. Stupid. Transuranics storage decay into fissionables. Stupid. Aircraft carriers and submarines put a premium on minimum volume reactors. Building military on acres of land is stupid.

An advocate makes virtue of failure. The worse the cure the better the treatment – and the more that is required. More studies!

Uncle Al needs to calm down.
