Pebble Mine (Copper/Gold Prospect) - Ground Truth Trekking

Nov 21, 2016· The AGRs get about 30% better thermal efficiency than light water reactors, but have a lower burnup on the fuel. They were also designed to be refueled at full power, which proved troublesome because of vibrations in the fuel assemblies. The German pebble bed reactor prototype had refueling problems too, with pebbles sticking in the chute.

A Medley of Potpourri: Molten salt reactor

A molten salt reactor (MSR) is a class of generation IV nuclear fission reactor in which the primary nuclear reactor coolant, or even the fuel itself, is a molten salt mixture. MSRs can run at higher temperatures than water-cooled reactors for a higher thermodynamic efficiency, while staying at low vapour pressure. The nuclear fuel may be solid or dissolved in the coolant.
