From the pages of Nuclear News: Industry update September 2024
Here is a recap of industry happenings from the recent past:
BWXT advanced nuclear reactor agreement signed
Burns & McDonnell, a family of construction and design companies, has entered into an agreement with BWX Technologies to further advance the design and development of the BWXT BANR microreactor, which has a “passively safe design” for powering remote facilities while providing a carbon-free source of heat and electricity. The two companies completed the first phase of their collaboration in early 2024 and intend to complete the second phase by the third quarter of 2025. Burns & McDonnell is helping BWXT develop the balance-of-plant systems for the BANR, generate the power plant layout, and perform preconstruction planning. Its scope of work also includes developing power cycle architecture, identifying critical components, integrating site design, and supporting steam and power distribution infrastructure and reactor building structures. The Wyoming Energy Authority is currently evaluating the feasibility of using the BANR in a state nuclear market for baseload heat and power deployed for remote industrial users, such as mining operations.

The leachability of a radioactive waste glass formulated to Bat telle Pacific Northwest Laboratory specification 80-207 has been studied using eight actual groundwaters with a range of chemical compositions as leachants. Waters collected from the Grande Ronde Basalt (Washington State) and from alluvial deposits in the Hualapai Valley (Arizona) were the most effective at removing plutonium from this glass. Leaching was shown to be incongruent; plutonium was removed from the glass more slowly than the overall glass matrix. The results of these experiments indicate the need to study the leachability of actual waste forms using the actual projected groundwaters that are most likely to come into contact with the waste should a radioactive waste repository be breached.
