DOE issues RFI for reuse of SRS heavy water

August 4, 2026, 9:24AMNuclear News

The Department of Energy’s Office of Environmental Management has issued a request for information for industry input about the best ways to reuse and repurpose as much as 530,000 gallons of heavy water that is currently being stored at the Savannah River Site in South Carolina. The deadline to submit responses to the RFI is September 21.

Detailed information about the RFI, including contact information and instructions for submissions, was published in the Federal Register. Responses can be emailed to heavywaterrfi@doe.gov with the subject line “EM Heavy Water RFI Collaboration Response.”

The Carolinas-Virginia Tube Reactor (CVTR), also known as Parr due to its location in Parr, S.C., was a 65-MWt (17-MWe) pressurized tube reactor. Construction began in January 1960, and the reactor reached initial criticality in March 1963. Commercial operation commenced in December 1963, and the reactor was permanently shut down in January 1967 after the test program was complete.

Is isotope science all sweetness and light? Recent headlines on research confirming the sweet taste of heavy water and the creation of the lightest isotope of uranium yet may give that impression. But the serious science behind these separate research findings has implications for human health and for the understanding of the process of alpha decay.

BWXT Canada Ltd. (BWXT) will work with Ontario Power Generation (OPG) subsidiary Laurentis Energy Partners in developing technology that will assist in the recycling of heavy water from OPG’s CANDU reactors, OPG’s Centre for Canadian Nuclear Sustainability (CCNS) announced on September 17.

The collaborative project will recycle heavy water used to cool Canadian pressurized heavy-water reactors such as those in OPG’s Pickering and Darlington nuclear power plants. Once recycled, the heavy water will be used in a growing number of non-nuclear applications that include pharmaceuticals, medical diagnostics, and next-generation electronics including fiber optics.
