Plutonium Disposition by Downblending and Disposal
Refreshments - A light breakfast will be served from 9:00 - 9:30am
Discussion - 9:30 - 10:45am
In the Plutonium Management and Disposition Agreement (PMDA), the United States and Russia have each committed to dispose of 34 metric tons of surplus weapons-grade plutonium. To implement the PMDA, the United States has been building a mixed oxide (MOX) fuel fabrication facility to convert the plutonium into nuclear reactor fuel. However, the estimated lifecycle cost of the MOX program has increased to approximately $30 billion, prompting the National Nuclear Security Administration (NNSA) to assess alternatives to the MOX approach.
NNSA recently released a report evaluating four options other than the MOX program. The downblending and disposal option is assessed favorably in terms of cost, timeliness, and technical risk, but it presents a new set of challenges. The option – mixing plutonium oxide with an inert material and disposal in the Waste Isolation Pilot Plant (WIPP) – would require modifying the PMDA and increasing the statutory capacity of WIPP (operations at WIPP are currently uncertain due to the February accidental radiation release).
A blog post providing a brief summary of the storied history of plutonium dispostion can be found here.
On June 4, the Center for Science, Technology and Security Policy of the American Association for the Advancement of Science is convening a breakfast panel to discuss the downblending and disposal option for plutonium disposition in light of the US-Russia PMDA. Discussion will follow presentations by Dr. Edwin Lyman, Union of Concerned Scientists, and Miles Pomper, James Martin Center for Nonproliferation Studies.
