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.

Nuclear materials and operations have been removed from an old building at the Y-12 National Security Complex, and that improves safety and reduces the risk to workers and the public, a federal safety board said.

The building, 9204-2, or Beta 2, is on the west side of Y-12. It’s one of nine buildings at the 811-acre site that once used machines known as calutrons to enrich uranium for atomic bombs as part of the top-secret Manhattan Project during World War II. It’s now used to produce lithium for nuclear weapons.

In an early September report, the Defense Nuclear Facilities Safety Board said Consolidated Nuclear Security and the National Nuclear Security Administration Production Office had officially downgraded Building 9204-2. It had been a category two hazard, but it is now less than category three. It’s considered non-nuclear.

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…]

Citizens calling for the abolition of nuclear weapons will gather in Oak Ridge on Saturday, August 4, at 10:30 a.m. at Alvin K. Bissell Park to commemorate the atomic bombing of Hiroshima, Japan, in 1945 and to call for the United States to sign and ratify the Treaty on the Prohibition of Nuclear Weapons, which was adopted in July 2017 by 122 nations, a press release said.

The Oak Ridge events on August 4 are sponsored by the Oak Ridge Environmental Peace Alliance, and they will include music and political theater as well as a report on ongoing nuclear weapons production activities at Y-12, the press release said.

“Y-12 represents the full circle in time,” said OREPA coordinator Ralph Hutchison. “The age of nuclear weapons started here, with the enrichment of the Little Boy bomb’s uranium. And it continues today, in the face of world condemnation, with the production of thermonuclear secondaries and plans for a new bomb production plant, the Uranium Processing Facility, which will continue to make nuclear bomb cores for decades to come.” [Read more…]

Y-12 part of extending life of nation’s oldest nuclear weapons

Posted at 11:54 pm June 4, 2018

The Y-12 National Security Complex in Oak Ridge is part of a program to extend the life of B61 bombs, the oldest nuclear weapons in the nation’s active stockpile, federal officials said.

The life extension program, or LEP, for the B61 bombs is the most complex and expensive since the U.S. Department of Energy began stockpile life extension activities in January 1996, according to the U.S. Government Accountability Office.

Critical components of the bombs are reaching the end of their operational lives, and the life extension program will result in a bomb known as B61-12. It will consolidate four versions of the bomb into one. The bombs could be carried on B-2A bomber aircraft and F-15E, F-16, F-35, and PA-200 fighters.

A GAO report described the role of six National Nuclear Security Administration sites and laboratories in the LEP. Besides Y-12, the NNSA sites are Kansas City National Security Campus in Missouri; Los Alamos National Laboratory in New Mexico; Pantex Plant in Amarillo, Texas; Sandia National Laboratories in Albuquerque, New Mexico; and Savannah River Site in Aiken, South Carolina.

Y-12 is designated as the production site for the secondary. All weapons in the U.S. nuclear stockpile are two-stage nuclear weapons, or thermonuclear weapons. The first stage, known as the primary, is a fission device that is the initial source of nuclear energy, the GAO said. The secondary, which is the second stage, is a nuclear stage physically separate from the primary. Together, the primary and secondary are referred to as the weapon’s nuclear explosive package, the GAO said. [Read more…]

Demolished building once helped protect city, enriched uranium at Y-12

A building that was mostly demolished on Wednesday once helped to protect enriched uranium at Y-12, and it was used by military police and the Oak Ridge Police Department to help protect the city.

The building at 101 Bus Terminal Road was once connected by radio to a Y-12 building that stored the world’s only supply of enriched uranium-235, according to a 2010 newspaper article published by D. Ray Smith, who cited Bill Sergeant, head of security after World War II.

A small section of the Bus Terminal Road building that still had historic artifacts—two holding cells and a heavy, bulletproof steel door—remained standing, surrounded by demolition debris, on Wednesday and Thursday. It’s not clear why that one section hadn’t been demolished yet, but the 2010 newspaper article by Smith said it had been a secure federal communications center and was built to be safe from attack. That small section of the building, which had no external windows, was reported to have a concrete ceiling that was one foot thick.

The building, which is at the intersection with Oak Ridge Turnpike, is now being completely demolished so a Taco Bell restaurant can be built there. The building had been extensively modified, and it’s not clear how much of it might have been considered historic.

Smith said the Bus Terminal Road building was once connected by radio to Building 9213, which stored uranium-235 for about a year at Y-12. Building 9213 is on the south side of Chestnut Ridge, which is on the south side of Y-12. After it briefly stored uranium, Building 9213 was used for criticality experiments for years, Smith said. It’s also been used to train the National Guard to identify and isolate radioactive sources as part of their training for homeland security. [Read more…]

The Manhattan Project National Historical Park will have a special premiere showing of the Minuteman Missile National Historic Site film, “Beneath the Plains,” in Oak Ridge on Saturday.

The film showing is scheduled at 3 p.m. Saturday at the American Museum of Science and Energy, which is at 300 South Tulane Avenue in Oak Ridge.

The 30-minute film gives visitors a glimpse of how 1,000 missiles were kept on constant alert, a press release said.

“Hidden in plain sight during the Cold War, these nuclear weapons stood as a deterrent against a nuclear attack to the United States and its allies,” the press release said. [Read more…]

DOE announces $1.8 billion program for new supercomputers, with one at ORNL

The U.S. Department of Energy announced a new supercomputing program on Monday that could be worth up to $1.8 billion and deploy two systems, with one at Oak Ridge National Laboratory, that would be 50 to 100 times more powerful than today’s computers.

The new systems are called exascale computers. DOE said the new supercomputers will solidify United States leadership in exascale computing.

The initiative was announced by U.S. Energy Secretary Rick Perry in Washington, D.C., on Monday. Perry announced a request for proposals, or RFP, for the development of at least two new exascale supercomputers to be deployed at DOE national laboratories sometime around 2021-2023.

“The new supercomputers funded through this RFP will be follow-on systems to the first U.S. exascale system authorized by Secretary Perry this past June, named Aurora, which is currently under development at Argonne National Laboratory and scheduled to come online in 2021,” a press release said. The RFP announced Monday envisions the possibility of upgrades to Aurora or even a follow-on system in 2022-2023, “depending on an assessment of needs and opportunities at that time.” [Read more…]

UPF lawsuit moved from DC to Knoxville

The federal lawsuit that asks for an environmental review of the new multi-building design for the Uranium Processing Facility at the Y-12 National Security Complex has been transferred from Washington, D.C., to Knoxville.

The transfer of the civil complaint had been requested in September by the defendants, U.S. Energy Secretary James Richard “Rick” Perry and Frank G. Klotz, former administrator of the National Nuclear Security Administration. The NNSA is an agency within the U.S. Department of Energy that manages nuclear weapons programs and facilities, including Y-12, among other activities.

United States District Judge Dabney L. Friedrich, who was assigned the case in December, granted the motion to transfer the lawsuit from the District of Columbia to U.S. District Court for the Eastern District of Tennessee, which includes the Knoxville division, on March 23.

The 44-page federal lawsuit, which was filed in U.S. District Court in Washington, D.C., on July 20, argues that a new environmental impact statement should be prepared for the new design for the UPF, the largest federal construction project in Tennessee since World War II. The plaintiffs allege that the NNSA’s decision to use several new buildings for the UPF, rather than just one, and continue to use some old buildings at Y-12 for some nuclear weapons work is risky because the old buildings could collapse during a major earthquake, possibly leading to a nuclear accident that could release radiological materials.

Federal officials denied that allegation and others in a 29-page response filed September 29. They’ve called some allegations vague, ambiguous, or speculative, and they have said that safety and technical analyses are under way at Y-12. Some buildings may require seismic upgrades, depending upon evaluation results, and an Extended Life Program is meant to ensure that two buildings—Building 9215 and Building 9204-2E—will safely support future operations, federal officials said.

Mercury contamination is one of the biggest problems remaining from the Cold War, U.S. Senator Lamar Alexander said during a groundbreaking ceremony on Monday morning. Alexander, a Tennessee Republican, first announced the new treatment facility at Y-12 more than four years ago.

“In May 2013, I came to Oak Ridge to announce that a new water treatment facility would be built at Y-12 at the head of the East Fork Poplar Creek to prevent mercury that was once used to make nuclear weapons from getting into our waterways,” Alexander said. “That day, I made a personal commitment to address one of the biggest problems we have from the Cold War era—mercury contamination—and help fund a solution. Today, I am proud to see that we are breaking ground on the new water treatment facility.”

Site preparation for the new Mercury Treatment Facility is expected to start this year, with the rest of construction beginning in late 2018. The facility is expected to start operating in late 2022.

The treatment plant will allow workers to demolish four large buildings where mercury, a toxic metal, was once used: Alpha 2, Alpha 4, Alpha 5, and Beta 4. Work on those buildings, mostly on the west side of Y-12, could start by 2024. [Read more…]
