Thoria hosted weapon plutonium incineration in thermal and fast reactors
Weapon grade plutonium (W-Pu) can be disposed by incineration using present day reactor technology. Burning Pu in reactors, however , is a relatively slow process and a disposition programme may take many decades to complete. In thermal pressurised water reactors (PWR), with typically 5% W-Pu enrichment, approximately 80% of the Pu can be burned in a standard 3-cycle operation (900 EFPD). In a fast system, with approximately 16% W-Pu enrichment 50% of the Pu is burned after 5 years. Use of a thorium matrix to host the W-Pu has the important advantage that, in addition to making the material as inaccessible as Pu in the spent fuel (thereby meeting the Spent Fuel Standard), no new plutonium is produced.
