Division Spotlight
Decommissioning & Environmental Sciences
The mission of the Decommissioning and Environmental Sciences (DES) Division is to promote the development and use of those skills and technologies associated with the use of nuclear energy and the optimal management and stewardship of the environment, sustainable development, decommissioning, remediation, reutilization, and long-term surveillance and maintenance of nuclear-related installations, and sites. The target audience for this effort is the membership of the Division, the Society, and the public at large.

DOE’s Wright appears before House subcommittee
Wright
Secretary of Energy Chris Wright testified before a hearing of the U.S. House of Representatives Committee on Appropriations, Subcommittee on Energy and Water Development and Related Agencies, on May 7, to answer questions about the DOE budget and priories for fiscal year 2026.
Wright’s testimony: Wright said that the DOE was taking steps to accelerate innovation in commercial nuclear development. “In the past 100 days, DOE has issued two disbursements to support the reopening of Michigan’s Palisades nuclear energy plant. We allocated high-assay low-enriched uranium material to five U.S. advanced nuclear reactor developers to boost domestic reactor deployment.”
He added that it was imperative for the nation to strengthen its nuclear future and that he would take immediate action to accelerate the deployment of small modular reactors.

Large quantities of weapon grade (WG) plutonium have been accumulated in the nuclear warheads. Plutonium and heavy water moderator can give a good combination with respect to neutron economy. TRISO type fuel can withstand very high fuel burn up levels. The paper investigates the prospects of utilization of TRISO fuel made of WG-plutonium in CANDU reactors. Three different fuel compositions have been investigated: 1: 90 % ThC + 10 % PuC, 2: 70 % ThC + 30 % PuC and 3: 50 % ThC + 50 % PuC. The temporal variation of the criticality k and the burn-up values of the reactor have been calculated by full power operation up to 17 years. Calculated startup criticalities for these fuel modes are k,0 = 1.6403, 1.7228, 1.7662, respectively. Attainable burn up values and reactor operation times with the same fuel charge will be 94 700, 265 000, 425 000 MW.D/MT and ~ 3.5, 10, 17 years, respectively. These high burn ups would reduce fuel fabrication costs and nuclear waste mass for final disposal per unit energy drastically.
