NRC seeks to better understand new radiological survey technologies

May 8, 2023, 12:00PMRadwaste Solutions

The Nuclear Regulatory Commission is issuing a request for information (RFI) aimed at understanding the current state-of-art radiological survey methods used to comply with decommissioning and license termination requirements. According to the commission, the information will help its staff better understand trends in radiological survey instrumentation and data analysis, including those used to survey both surface and subsurface residual radioactivity.

U.K. decommissioning bureau releases three-year business plan

April 26, 2023, 9:30AMRadwaste Solutions

The Nuclear Decommissioning Authority, the governmental organization responsible for the cleanup and decommissioning of the United Kingdom’s 17 nuclear sites, has released its business plan for the fiscal years running from April 1, 2023, through March 31, 2026. The plan provides a summary of the activities and progress the NDA expects to make at its nuclear sites over the next three years.

In introducing the report, NDA group chief executive officer David Peattie wrote, “This business plan sets out a challenging program of work, reducing hazards while contributing to a globally significant sustainability agenda, developing our people, and supporting our communities.”

The full report Nuclear Decommissioning Authority Business Plan: 1 April 2023 to 31 March 2026 can be found here.

Underwater Construction Corporation (UCC) UK Ltd. announced that it has recently completed a nuclear diving pilot project at the Pile Fuel Storage Pond (PFSP) at the Sellafield nuclear site in Cumbria, England. UCC UK said the project marks a significant decommissioning milestone for Sellafield, demonstrating the capability of the company’s methods and equipment to remediate the legacy nuclear pond while limiting worker dose.

The oldest pool on the Sellafield site, the PFSP was constructed between the late 1940s and early 1950s as a storage and cooling facility for irradiated fuel and isotopes from the two Windscale reactors and was in full operation until 1962. Then through the mid-1970s, the pond facility, one of six on the site, was used for storage of intermediate-level waste and fuel from the U.K. nuclear program.

Nuclear dismantling and decommissioning company APTIM said it is on schedule to wrap up field activities decommissioning the U.S. Navy’s Surface Ship Support Barge (SSSB) by April, with project closure slated for June. The company announced yesterday that its team has completed the demolition of the barge’s former spent fuel water pool, also referred to as the “wet pit,” or the heart of the vessel.

NRC report updates decommissioning cost guidance

February 14, 2023, 9:58AMRadwaste Solutions

The Nuclear Regulatory Commission has updated its guidance for nuclear power plant owners and operators in estimating the cost of decommissioning their reactors. Licensed power reactor operators are required under NRC regulations to annually adjust the estimated costs (in current-year dollars) of decommissioning their plants to ensure that adequate funds are available when needed.

The U.S. Department of Transportation has drafted a programmatic agreement (PA) on the decommissioning the NS Savannah, the world’s first nuclear-powered merchant ship. Christened in 1959 under President Dwight Eisenhower’s Atoms for Peace initiative, which challenged world leaders to develop peaceful uses of nuclear power, the ship served as a demonstration project for the potential maritime use of nuclear energy.

Paducah breaks ground on new site emergency operations center

Construction crews at the Department of Energy's Paducah Site in Kentucky have broken ground on a new Emergency Operations Center (EOC) to improve coordination and response to emergencies across the site.

The 3,500-square-foot facility will replace the existing EOC, which was established in the site’s C-300 Control Building around 1990. The C-300 Control Building was built during the 1950s. The new modern facility will be used to monitor environmental conditions and house emergency management personnel.

The new EOC is scheduled for completion in this year.

A video is available on the construction of the new EOC.

A new animated video from the Department of Energy's Office of Environmental Management (EM) shows how cleanup contractor CH2M HILL BWXT West Valley (CHBWV) will take down the main plant process building at the West Valley Demonstration Project (WVDP).

The EM team at West Valley wanted to convey the project to the public, and they believe the animation accomplishes that goal, according to Stephen Bousquet, EM WVDP federal project director for the Main Plant Deconstruction Project.
