The Department of Energy’s Office of Environmental Management (EM) has made great progress in accomplishing its cleanup of legacy radioactive waste but has yet to tackle its most challenging tasks, including the treatment of liquid tank waste at the Hanford, Idaho, and Savannah River sites. That was the consensus of the DOE-EM officials who took part in a panel session of the 2023 Waste Management Symposia, held February 26–March 2 in Phoenix, Ariz.

A fire broke out at the Y-12 National Security Complex in Oak Ridge, Tenn., earlier today. According to Y-12’s Facebook page, one of the site’s production buildings had a fire in a hood at approximately 9:15 a.m. Y-12 emergency services responded to the event and precautionary protective actions were initiated for employees who were in the vicinity of the incident and who were not involved in the emergency response.

Work has begun to prepare the Savannah River Plutonium Processing Facility (SRPPF) at the Department of Energy’s Savannah River Site in South Carolina for its future national security mission: the manufacturing of plutonium pits for the National Nuclear Security Administration.

On December 5, researchers at the National Ignition Facility (NIF) at Lawrence Livermore National Laboratory achieved fusion energy breakeven. It was a gain for stockpile stewardship that also—as headlines gushed prior to the Department of Energy’s December 13 announcement—boosted the prospects of inertial fusion energy (IFE). The timing of the landmark achievement may have been especially welcome to private fusion companies with inertial or hybrid magneto-inertial confinement concepts, because it occurred as the DOE was getting ready to consider applications for $50 million in funding for fusion pilot plant design work.

It’s official: Early in the morning on December 5 at Lawrence Livermore National Laboratory’s National Ignition Facility (NIF), the laser-triggered implosion of a meticulously engineered capsule of deuterium and tritium about the size of a peppercorn yielded, for the first time on Earth, more energy from a fusion reaction than was delivered to the capsule. The input of 2.05 megajoules (MJ) to the target heated the diamond-shelled, spherical capsule to over 3 million degrees Celsius and yielded 3.15 MJ of fusion energy output. The achievement was announced earlier today by officials and scientists representing the Department of Energy and its National Nuclear Security Administration, the White House, and LLNL during a livestreamed event.

NorthStar Medical Radioisotopes has completed construction and all equipment installation at its new facility in Beloit, Wis., to produce the medical radioisotope molybdenum-99 without the use of high-enriched uranium, the Department of Energy’s National Nuclear Security Administration announced last week.

The Department of Energy’s Office of Environmental Management (EM) announced on October 18 that it has begun the process of transferring primary authority of South Carolina’s Savannah River Site (SRS) to the National Nuclear Security Administration, with the transfer expected to be completed in 2025.

Work crews at the Department of Energy’s Oak Ridge Site in Tennessee have successfully completed the demolition of the former Criticality Experiment Laboratory. Crews worked this past summer to bring down the dilapidated 1940s-era facility, also known as Building 9213.

The National Nuclear Security Administration announced that, in compliance with the National Environmental Policy Act (NEPA), it intends to prepare a site-wide environmental impact statement (SWEIS) to analyze the potential environmental impacts for continuing operations of the Los Alamos National Laboratory for the next 15 years. The SWEIS will also analyze the environmental impacts of legacy waste remediation being done by the Department of Energy’s Office of Environmental Management at the site.

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.

The National Nuclear Security Administration announced last week that it is canceling its November 2020 contract solicitation for management and operation of the Pantex Plant and Y-12 National Security Complex and terminating the contract award announced in November 2021 for the two sites. The NNSA intends to hold two new competitions for separate contracts to manage each site.

The Department of Energy’s National Nuclear Security Administration is establishing an Energy Resilient Infrastructure and Climate Adaptation (ERICA) initiative, which will help position it to deal with climate issues. In a recent press release, the NNSA noted that ERICA will help it to meet the requirements of federal legislature and executive orders, along with the DOE’s climate adaptation, energy resilience, and sustainability goals in support of the agency’s national security missions.
The initiative was outlined in President Biden’s fiscal year 2023 budget request for the DOE.
