Workers are making significant progress removing asbestos and other hazardous waste from the Biology Complex at the Y-12 National Security Complex in a deactivation project that’s more than 60 percent complete, the U.S. Department of Energy said this week.

The work prepares the Biology Complex for demolition, possibly next year. The Biology Complex was originally built to recover uranium from process streams. It was later used for DOE’s research on the genetic effects of radiation from the late 1940s. When they operated, the facilities once had more people with doctorates than anywhere in the world, according to DOE.

Asbestos abatement teams from UCOR are working inside the six-story 9207 Facility and the three-story 9210 Facility. The first building is 256,600 square feet, and the second is 64,700 square feet.

“This project paves the way for EM (Environmental Management) to begin demolishing remaining buildings that comprise the Biology Complex next year,” the U.S. Department of Energy Office of Environmental Management said in an “EM Update” newsletter on Tuesday.

Note This story was last updated at 9:38 a.m. Sept. 25.

A federal judge in Knoxville on Tuesday said a critical decision made in 2016 for enriched uranium operations at the Y-12 National Security Complex, including for the $6.5 billion Uranium Processing Facility, violated a national environmental law, and she ordered the decision vacated, or set aside.

The UPF is already under construction, and Wedenesday morning, the National Nuclear Security Administration, which oversees work at Y-12, said construction will continue.

The 104-page opinion and order was filed in U.S. District Court on Tuesday by Chief U.S. District Judge Pamela L. Reeves.

One of the plaintiffs said the decision to vacate the amended record of decision published in the Federal Register in 2016 means the NNSA no longer has the legal authority to continue construction work at UPF.

But the NNSA said it was pleased that the court’s memorandum opinion rejected almost all of the plaintiff’s claims regarding National Environmental Policy Act violations related to UPF construction.

“However, with the court agreeing that there was inadequate consideration of new information concerning seismic hazards at Y-12, NNSA will review the seismic analysis while conferring with the Department of Justice on the possibility of appeal,” the NNSA said. “In the meantime, construction of UPF will proceed.”

Besides the amended record of decision, Reeves said supplement analyses prepared in 2016 and 2018 also violated the National Environmental Policy Act, or NEPA, and she said they were to be set aside as well.

Work began in June to build the Mercury Treatment Facility at the Y-12 National Security Complex.

The Mercury Treatment Facility will allow the U.S. Department of Energy to clean up and demolish several large Y-12 buildings that used mercury to separate lithium for nuclear weapons during the Cold War in the 1950s and 1960s. The facility is expected to help reduce the amount of mercury in East Fork Poplar Creek, which flows through Oak Ridge.

DOE announced in December that it had awarded a $91 million contract to build the Mercury Treatment Facility. The contract, which could be in place for up to four years, was awarded to APTIM-North Wind Construction JV LLC.

A groundbreaking was held at the site in November 2017, and site preparations were completed by December 2018.

Y-12 supporting work to make most widely used medical isotope

Note: This story was updated at 5:30 p.m.

The Y-12 National Security Complex in Oak Ridge is supporting a program to make an isotope used in more than 40,000 medical procedures across the nation each day. The goal is to produce the isotope, molybdenum-99 (Mo-99), in the United States without using highly enriched uranium.

Some of that work could occur in Oak Ridge. A company called Coquí Radio Pharmaceuticals Corporation announced in April that it plans to build a $500 million medical isotope production facility at the Heritage Center in west Oak Ridge. Coquí’s facility would make medical isotopes, primarily Mo-99, and the company could start production in 2025.

In a video posted online, Y-12 said some of its researchers have extensive knowledge of Mo-99 and are sharing that information with Coquí and other companies hoping to produce the isotope.

Y-12 has been involved with Mo-99 since 2009, said Cole Jackson of Y-12 Global Security and Strategic Partnerships.

No injuries were reported when a furnace door blew open during an “unexpected violent reaction” in a chemistry laboratory at the Y-12 National Security Complex in May.

The door of the muffle furnace blew open while it was heating samples in an analytical chemistry laboratory in Building 9995 on Thursday, May 30, the Defense Nuclear Facilities Safety Board said.

The muffle furnace was damaged, the DNFSB said. It is used to heat samples to high temperatures. The glass vials containing the samples shattered, and some were expelled from the muffle furnace into the work area, the safety board said in a June 7 report.

Almost 700 kilograms of highly enriched uranium has been moved from the United Kingdom to the United States, and the material is being securely stored at the Y-12 National Security Complex in Oak Ridge for now, federal officials said.

The National Nuclear Security Administration said this month that the highly enriched uranium, or HEU, will be down-blended later into low enriched uranium for use as nuclear reactor fuel.

“The material was returned to Y-12 for secure storage awaiting future disposition,” the NNSA said in a statement provided Friday by Steven Wyatt of the NNSA Production Office in Oak Ridge.

Wyatt said Y-12 supported the removal effort, which was announced by the NNSA on May 3, through technical oversight and guidance of the processing and packaging of material.

A new lithium processing facility that could be built in Oak Ridge is a priority for the National Nuclear Security Administration, which has cited worker safety and materials that have fallen from the ceiling at the old building now used at the Y-12 National Security Complex.

As a priority, the new lithium processing facility is right behind the number one priorities: the production of plutonium pits at the Savannah River Site in South Carolina and Los Alamos National Laboratory in New Mexico and uranium processing at the Uranium Processing Facility, which is now under construction at Y-12, said Charles Verdon, NNSA deputy administrator for defense programs.

NNSA Administrator Lisa Gordon-Hagerty cited the materials that have fallen from the ceiling at the old Y-12 building used for lithium processing, 9204-2, or Beta 2, in her response to questions during a budget hearing with the U.S. House Energy and Water Development Subcommittee on Tuesday.

(For members) DOE could lease space to store elemental mercury

By Leave a Comment

Image from “Final Long-Term Management and Storage of Elemental Mercury Supplemental Environmental Impact Statement” published by U.S. Department of Energy in September 2013.

The U.S. Department of Energy is considering whether to lease space to store elemental mercury from sites across the country.

The facility could store about 1,200 metric tons (1,300 tons) of elemental mercury. The waste has been generated at sites in the United States, mostly at gold mining operations, according to the DOE Office of Environmental Management.

The mercury that could be stored at the leased facility is separate from the 1,200 metric tons of mercury stored at the Y-12 National Security Complex in Oak Ridge. The Y-12 mercury, about 2.6 million pounds stored in seamless steel flasks, was acquired for lithium-6 isotope separation operations for thermonuclear weapons.

Canned subassembly certified four months ahead of schedule

The Y-12 National Security Complex on Monday said it has completed a major milestone in efforts to refurbish components for a strategic nuclear weapons system that is vital to the U.S. nuclear deterrent.

The first production unit for a bomb called the B61-12 was certified at Y-12 on December 6, 2018.

The work is part of the B61 Life Extension Program, or LEP. The B61 is a nuclear bomb that can be carried on several types of military aircraft. The B61 LEP will extend the life of this strategic weapon for 20 years, said Consolidated Nuclear Security LLC, which manages and operates Y-12 for the National Nuclear Security Administration.

B61 bombs are the oldest nuclear weapons in the nation’s active stockpile. They have been in service almost 50 years, and critical components of the bombs are reaching the end of their operational lives. The B61 was first “fielded” in 1968, and current modifications were fielded between 1979 and 1991, according to the U.S. Government Accountability Office. [Read more…]
