The U.S. Department of Energy has awarded a $91 million contract to build the Mercury Treatment Facility at the Y-12 National Security Complex.

It’s part of an effort to reduce the amount of mercury in East Fork Poplar Creek and allow the demolition of several large Y-12 buildings where mercury was used to help make nuclear weapons during the Cold War.

The contract, which could be in place for up to four years, was awarded to APTIM-North Wind Construction JV LLC, DOE said Tuesday. [Read more…]

Experiments and isotope production have been affected, but employees are still able to carry out their normal duties at the High Flux Isotope Reactor as the U.S. Department of Energy investigates a slightly elevated radiation level in HFIR’s primary cooling system.

The High Flux Isotope Reactor, which is used for research and isotope production, is at Oak Ridge National Laboratory.

In a response to questions on Wednesday, ORNL Communications Director David Keim said the slightly elevated reading in the primary cooling system was well below alarm levels.

“The HFIR operators promptly responded to the reading and placed the reactor in a safe condition,” Keim said. [Read more…]

Note: This story was updated with a statement from CNS at 11:50 a.m. Nov. 19.

The U.S. Department of Energy has notified Consolidated Nuclear Security that it intends to investigate possible weaknesses in nuclear criticality controls at the Y-12 National Security Complex.

The DOE Office of Enterprise Assessments’ Office of Enforcement notified CNS, which manages and operates Y-12, of its intent to investigate on Tuesday. The Office of Enforcement intends to investigate potential noncompliances with DOE nuclear safety program requirements, according to a summary of the notice published online.

The potential nuclear criticality control weaknesses were identified at Y-12 between May 2017 and May 2018, the notice said.

Nuclear criticality occurs when nuclear fuel is capable of sustaining a fission chain reaction. [Read more…]

Researchers at Oak Ridge National Laboratory have demonstrated a 120-kilowatt wireless charging system for vehicles—providing six times the power of previous ORNL technology and a big step toward charging times that rival the speed and convenience of a gas station fill-up.

The wireless system transfers 120 kilowatts of power with 97 percent efficiency, which is comparable to conventional, wired high-power fast chargers. In the laboratory demonstration, power was transferred across a six-inch air gap between two magnetic coils and charged a battery pack.

ORNL researchers created and demonstrated the world’s first 20-kilowatt wireless charging system, which is being modified for applications such as commercial delivery trucks.

“It was important to maintain the same or smaller footprint as the previous demonstration to encourage commercial adoption,” said project lead Veda Galigekere of ORNL’s Power Electronics and Electric Machinery Group. [Read more…]

The Y-12 National Security Complex in Oak Ridge has been approved to produce a major component of a nuclear bomb known as the B61-12.

The approval was the final step to authorize the manufacturing and delivery of the first production unit of a component called the canned subassembly. It’s scheduled for March 2019, according to Y-12. A canned subassembly is the second stage of a modern thermonuclear weapon, and it is part of the nuclear explosives package.

The Y-12 work is part of the B61-12 Life Extension Program, which will consolidate four versions of the bomb into one. The bombs could be carried on B-2A bomber aircraft and F-15Es, several types of F-16s, and PA-200 fighters, and in the future, F-35s and B-21s.

Public availability session on proposed DOE landfill is Thursday

Posted at 2:18 pm October 8, 2018
By John Huotari Leave a Comment

There is a public availability session on the proposed federal landfill in Oak Ridge on Thursday.

The U.S. Department of Energy has issued a proposed plan to build a new landfill on the Oak Ridge Reservation. The landfill, the Environmental Management Disposal Facility, would be in Bear Creek Valley west of the Y-12 National Security Complex. It is intended for disposal of radioactive, hazardous, and toxic wastes. It would be used as cleanup work ends at the East Tennessee Technology Park and the existing landfill, the Environmental Management Waste Management Facility fills up, and cleanup work moves to Y-12 and Oak Ridge National Laboratory.

A press release said the Sierra Club has invited state and federal officials from DOE, Environmental Protection Agency, and Tennessee Department of Environment and Conservation to be available for public questions about the Environmental Management Disposal Facility. The public availability session has been scheduled from 2 to 8 p.m. Thursday, October 11, at the TDEC office at 761 Emory Valley Road in Oak Ridge. [Read more…]

Centrus Energy Corporation has a $15 million project to prepare K-1600, a building in the middle of the historic K-25 “footprint,” for demolition.

On Tuesday, Centrus announced that it had received a work authorization from the U.S. Department of Energy for decontamination and decommissioning (D&D) work at the building. The work will include removing and disposing of equipment and materials to make K-1600 non-radiologically contaminated and non-possessing (i.e. unclassified), a press release said. The work will occur between October 1, 2018, and September 30, 2019.

After the work is completed, DOE will be able to turn over K-1600 to a contractor to demolish it, the press release said. It’s one of the last remaining “legacy structures” on the 2,200-acre site of the World War II-era K-25 uranium enrichment plant, now known as the East Tennessee Technology Park, the press release said.

Many other buildings have been demolished there, including the five large gaseous diffusion buildings once used to enrich uranium for atomic weapons and commercial nuclear power plants. ETTP is now being converted into a large industrial park in west Oak Ridge. [Read more…]

About 20 metric tons of highly enriched uranium could be “down-blended” to low-enriched uranium and transferred to the Tennessee Valley Authority for use as a fuel to produce tritium for nuclear weapons, according to a public notice published in the Federal Register this week.

The project involves the Y-12 National Security Complex in Oak Ridge and Watts Bar Nuclear Plant near Spring City in Rhea County, among other sites.

The National Nuclear Security Administration and TVA announced in August that they intend to enter into an agreement to “down-blend” highly enriched uranium to low-enriched uranium in order to help produce tritium, a key “boosting” component in nuclear weapons.

The highly enriched uranium used for the “down-blending” will be processed, packaged, and shipped from Y-12, according to the NNSA. Y-12 is an NNSA site, and it is the main storage facility for certain categories of highly enriched uranium. [Read more…]
