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.

Hinkley Point C gets over $6 billion in financing from Apollo
U.S.-based private capital group Apollo Global has committed £4.5 billion ($6.13 billion) in financing to EDF Energy, primarily to support the U.K.’s Hinkley Point C station. The move addresses funding needs left unmet since China General Nuclear Power Corporation—which originally planned to pay for one-third of the project—exited in 2023 amid U.K. government efforts to reduce Chinese involvement.

The United States and the Russian Federation have agreed to dispose of their excess weapons-grade plutonium, with consuming the material as nuclear fuel in light water reactors for electricity generation often discussed as the best option. Lightbridge Corporation has several thermal reactor fuel designs that offer very high burnups, in the range of 21 at. % or approximately 190 900 MWd/tonne of heavy metal, which make them well suited for consuming excess weapons-grade plutonium. MCNP6.2 computer simulations were performed to quantify the mass of plutonium consumed in a Lightbridge-designed fuel rod compared to traditional mixed-oxide (MOX) fuel, as well as the attractiveness of the plutonium in the used fuel for weapons purposes. The results of these simulations show that the Lightbridge plutonium disposition fuel variant consumes approximately 5.5 times more plutonium per fuel rod than MOX fuel and that the material attractiveness of the Lightbridge-used plutonium is noticeably less than that of MOX fuel.
