Representatives from the Japan Nuclear Damage Compensation and Decommissioning Facilitation Corporation (NDF) recently visited the Department of Energy's Office of Environmental Management (EM) headquarters in Washington, D.C., and the Hanford Site in Washington state to promote collaboration and provide updates on the status and plans to decommission Japan's Fukushima Daiichi nuclear power plant. The Great East Japan Earthquake of March 11, 2011, caused damage to the plant and surrounding communities. The NDF was created in September 2011 to oversee the decommissioning and cleanup of the plant, which is owned by the Tokyo Electric Power Company.

The rapid changes in the nuclear energy industry over the last decade, driven in part by fluctuating energy market prices and an aging fleet of reactors, have led to the closure of multiple reactors in the United States and other countries. These closures have increased the need for larger and more efficient ways to manage low-level radioactive waste processing and transport capacities. The safe transport of radioactive material is a key component of the overall nuclear industry reliability. Though sometimes perceived as a bottleneck and costly, it is necessary to send waste material to disposal.

The Nuclear Regulatory Commission announced that it has released the site of the La Crosse boiling water reactor in Wisconsin for unrestricted public use. The action comes after the NRC found that EnergySolutions subsidiary LaCrosseSolutions had met the agency’s radiation protection standards in decommissioning the nuclear power plant.

NRC report updates decommissioning cost guidance

Tue, Feb 14, 2023, 3:58PMRadwaste 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 need for sustainable nuclear/alpha skills in the U.K.: A Sellafield perspective

Fri, Feb 10, 2023, 9:01PMNuclear NewsHenry Hickling

The United Kingdom’s nuclear renaissance

The United Kingdom’s nuclear industry is expanding, with the U.K. government committed to supporting the build of more civil nuclear power plants (deployments up to 24 GW by 2050)1 while also undertaking large-scale decommissioning work in parallel.2 The defense sector is experiencing growth with the decommissioning, operation, and new build of submarines, plus managing the U.K.’s deterrent.3 Although the civil and defense programs are separate, they draw on the same group of skills and people.

NRC proposes to amend its rules on the use of credit ratings

The Nuclear Regulatory Commission has issued a proposed rule that would amend its regulations for approved financial assurance mechanisms for decommissioning. The rule is intended to implement the provisions of the 2010 Dodd-Frank Wall Street Reform and Consumer Protection Act that directed agencies to amend their regulations to remove any reference to or requirement of reliance on credit ratings.

Aecon-Wachs to help repurpose Savannah River’s MOX fuel facility

Aecon-Wachs, the U.S. division of Aecon Nuclear, has been tapped to support the Department of Energy’s goal of repurposing the unfinished Mixed Oxide Fuel Fabrication Facility at the Savannah River Site (SRS) in South Carolina. Known as Building 226-F, the facility is being transitioned into the Savannah River Plutonium Processing Facility (SRPPF) to produce plutonium pits for the nation’s stockpile of nuclear weapons.

The Decommissioning of Portsmouth’s X-326

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) announced that construction of Hanford’s K East Reactor cocoon has been completed ahead of schedule and under budget. Cocooning of K East—enclosing it in a protective steel structure while the reactor’s radioactivity naturally decays—was one of EM’s key construction priorities for 2022.

The trouble with tritium

Mon, Oct 31, 2022, 12:00PMNuclear NewsJames Conca

The trouble with tritium is there is no trouble with tritium.

At any level outside the laboratory, either experimental or manufacturing, tritium is harmless. Every year, we routinely release millions of gallons of slightly tritiated water to the ocean, large lakes, and large rivers from almost every commercial nuclear reactor in the world, and have done so for decades, all in accordance with globally accepted nuclear safety standards. And no adverse effects on the environment or humans have ever been seen.
