The disposal of nearly 100 tonnes of weapons-grade plutonium (WG-Pu) made surplus by the disarmament treaties is receiving urgent attention, highlighted by the recent seizure in Germany of small quantities of weapons-useful plutonium. Unlike highly enriched uranium, simple denaturing cannot make this plutonium worthless for use in future weapons. The use of physical security and institutional barriers, including long-term storage in high-level waste repositories, to provide secure storage for centuries to come is questionable when considering government instability and the possibility of national recidivism. The Russian Ministry for Atomic Energy (MINATOM) and General Atomics have signed an agreement for the cooperative design of a gas turbine-modular helium reactor (GT-MHR) to burn the WG-Pu stockpile. A formal proposal for a joint U.S./Russian program for the development of this reactor has been submitted by MINATOM to Vice President Gore. The major benefit of this program is that the reactor would deplete the Russian surplus plutonium stockpile, provide jobs for technical specialists in the former weapons complex, and produce valuable electric power. It would also provide a mutually assured means of destroying the U.S. and Russian stockpiles.
