TRISO

Fuel for these nuclear reactors is in the form of TRISO particles less than a millimeter in diameter.

General Atomics say that the MHR has a neutron spectrum is such and the TRISO fuel so stable that the reactor can be powered fully with separated transuranic wastes (neptunium, plutonium, americium and curium) from light water reactor used fuel.

The reactor core will be a fixed, annular bed with about 80,000 fuel elements each up to 60 mm diameter and containing approximately 9 grams of heavy metal as TRISO particles, with expected average burn-up of 80 GWd/t.

There are two ways in which these TRISO fuel particles are arranged: in blocks — hexagonal 'prisms' of graphite — or in billiard ball-sized pebbles of graphite encased in silicon carbide, each with about 15,000 fuel particles and 9g uranium.

Next Big Future 2009

There is a $7 million project to work on achieving deep burn (60-70\% burnup) of TRISO fuel pebbles. 3 to 20 times more uranium can be used in one pass through a reactor.
