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.
Demolition and disposal shifted into high gear this spring at the DOE’s former uranium enrichment plant in Ohio.
In the 1950s, the U.S. Department of Energy constructed the Portsmouth Gaseous Diffusion Plant in rural southern Ohio to enrich uranium, alongside two other federally owned and managed facilities in Oak Ridge, Tenn., and Paducah, Ky. The Cold War-era plant was built as a self-sufficient industrial city with more than 400 buildings and facilities centered around three massive gaseous diffusion process buildings that could enrich the level of the uranium-235 isotope for nuclear fuel in the defense and energy sectors.

The Department of Energy’s Office of Environmental Management (EM) said it has met one of its cleanup priorities for 2022 by beginning demolition of the Main Plant Process Building (MPPB) at the West Valley Demonstration Project (WVDP) in New York. Located 35 miles south of Buffalo, the 150-acre WVDP site is home to the only commercial spent nuclear fuel reprocessing facility to operate in the United States.
The San Onofre nuclear power plant.
The San Onofre Nuclear Generating Station (SONGS) recently shared a few videos on its YouTube channel, showing recent progress Southern California Edison has made in dismantling the plant’s turbine building. Decommissioning of the nuclear power plant, which permanently ceased operations in 2013, is being conducted by SONGS Decommissioning Solutions, a joint venture of EnergySolutions and AECOM.

A contractor for the Department of Energy’s Office of Environmental Management (EM) started tearing down a 1940s-era facility in May at the Y-12 National Security Complex in Oak Ridge, Tenn. Demolition of the former Criticality Experiment Laboratory, also known as Building 9213, is the latest project by EM to address a large inventory of high-risk excess contaminated facilities at the Oak Ridge Reservation.

A nearly yearlong effort to de-tension and remove more than 400 steel cables, known as tendons, from the two containment domes of the San Onofre Nuclear Generating Station (SONGS) was recently completed, with only one minor first aid incident recorded, according to Southern California Edison.

The U.S. Army Corps of Engineers is set to begin decommissioning SM-1A, the mothballed nuclear power reactor at Fort Greely, in Alaska, beginning next year, a project that is expected to take approximately six years. The USACE said it expects to release a request for proposals soliciting contractor bids for the decommissioning and dismantlement project by late summer.

Final cleanup activities at the Hanford Site’s demolished Plutonium Finishing Plant have resumed following a pause in work prompted by the COVID-19 pandemic, the Department of Energy announced. Crews with the DOE’s Richland Operations Office and site contractor Central Plateau Cleanup Company will remove, package, and dispose of rubble remaining from the demolition of the plant’s plutonium reclamation facility, which was torn down in 2017.

Towed from its home in Newport News, Va., the U.S. Navy’s Surface Ship Support Barge has arrived in Mobile, Ala., for decommissioning, Advance Local Alabama reported on June 1. The 268-foot-long barge operated from 1964 to 2016, supporting the Navy's nuclear vessel refueling and functioning like a spent fuel pool at a commercial nuclear power plant.

The transfer of the Indian Point nuclear power plant from Entergy to Holtec International and its subsidiaries was completed last week. Under the asset transfer deal, Holtec Indian Point becomes owner of the closed plant, with Holtec Decommissioning International serving as the site’s license holder and decommissioning operator.

Paving the way for increased automation in nuclear decontamination and decommissioning and waste management, French nuclear company Framatome announced that testing has confirmed the operation of its robotic systems for handling and sorting high-dose waste components.

A community advisory board has been formed for the decommissioning of Unit 2 of the Three Mile Island nuclear power plant, according to a March 23 report by StateImpact Pennsylvania, a collaboration of National Public Radio member stations. The Nuclear Regulatory Commission approved in December the transfer of TMI-2 and its license to TMI-2 Solutions for decommissioning. TMI-2 Solutions is a subsidiary of EnergySolutions.
According to the report, the TMI-2 Community Advisory Panel (CAP) is made up of 15 people who represent the plant and its neighbors, including townships, school districts, first responders, nuclear planners, and state historians. The group is being led by Londonderry Township manager Steve Letavic.
TMI-2 Solutions said that it will provide quarterly decommissioning updates to the TMI-2 CAP. As a volunteer non-regulatory organization, the CAP will provide community feedback to TMI-2 Solutions, including any issues or concerns related to TMI-2 decommissioning activities.
