As the result of a congressional mandate, the Department of Energy’s (DOE’s) National Nuclear Security Administration has asked the National Academies to evaluate the general feasibility of DOE’s plans to dispose of diluted weapons-grade plutonium at the Waste Isolation Pilot Plant (WIPP). A committee of 13 experts from academic, government, industrial, and independent consultant backgrounds will hold five public meetings including one each in South Carolina and New Mexico to gather information. An interim report will be released in late-2018 and a final report released in mid-2019.
