NNSA administrator resigns

Posted at 9:24 am November 11, 2020

Lisa Gordon-Hagerty

Lisa Gordon-Hagerty, the administrator of the National Nuclear Security Administration, resigned Friday.

The NNSA oversees the work at the Y-12 National Security Complex in Oak Ridge and other nuclear weapons sites across the nation. The NNSA, which is part of the U.S. Department of Energy, maintains nuclear warheads, produces fuel for the nuclear navy, and works on nuclear nonproliferation, among other activities.

Gordon-Hagerty, who was also under secretary of energy for nuclear security, became the first woman to lead the NNSA in February 2018.

It’s not clear why she resigned Friday or whether her resignation was voluntary.

Defense News reported that the resignation was driven by almost a year of clashes between Gordon-Hagerty’s office and Energy Secretary Dan Brouillette, including over budgets.

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.

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.

After two decades, work was completed in December on a program to extend the life of the W76 nuclear warhead, the Y-12 National Security Complex said on Monday.

That ended a decade of work to extend the service life of the original warhead design by 40 years, Y-12 said.

“This warhead plays a vital role in maintaining the nation’s credible nuclear deterrent,” said Consolidated Nuclear Security LLC, which manages and operates Y-12 for the National Nuclear Security Administration.

The Life Extension Program, or LEP, is for the W76-1 warhead. The W76-1 is a refurbished W76-0 warhead. The W76-0 warhead is a submarine-launched ballistic missile system that was first introduced into the stockpile for the U.S. Navy in 1978. The warhead is deployed with Trident II D5 missiles on Ohio-class nuclear ballistic missile submarines. [Read more…]

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…]

The Y-12 National Security Complex in Oak Ridge manufactured the uranium reactor core for a federal experiment that tested whether a nuclear energy source could provide power for space exploration.

“The full-power run showed that it may be feasible for NASA to use small fission reactors for deep space exploration and manned missions to the moon and Mars,” the National Nuclear Security Administration said in May.

The NNSA, which is part of the U.S. Department of Energy, worked with NASA (the National Aeronautics and Space Administration) on the project. It’s nicknamed KRUSTY, an acronym for Kilowatt Reactor Using Stirling Technology.

“In a joint venture with NASA last year, NNSA completed final design, fabrication, and full-power testing of a nuclear criticality experiment that can be used for a manned lunar or Mars space mission,” NNSA Administrator Lisa Gordon-Hagerty said in a post published on Twitter on Friday.

The uranium reactor core from Y-12 was delivered to the National Criticality Experiments Research Center at the Nevada National Security Site in the fall of 2017. [Read more…]

The National Nuclear Security Administration is preparing to restart a program to replace the W78 nuclear warhead, and new facilities at the Y-12 National Security Complex could be important to that project, a federal agency said Friday.

The W78 is one of two types of warheads on U.S. Air Force intercontinental ballistic missiles. The W87 is the other.

Critical components inside the W78 are aging, according to the U.S. Government Accountability Office, which published a report about the warhead replacement program on Friday. Also, the military’s requirements for, among other things, the safety and security features of the warhead have changed since it entered the stockpile in 1979, the GAO said.

Besides being used by the Air Force, the replacement W78 warhead could be used in ballistic missiles launched from Navy submarines, although further studies are required, the GAO said.

The two Y-12 facilities that could affect the warhead replacement program are the Uranium Processing Facility, which is now under construction, and the Lithium Production Facility, which could have a new building through a project that is still in the planning stages. [Read more…]

(For members) NNSA modernizing weapons as U.S. nuclear stockpile shrinks

Posted at 3:44 pm December 2, 2018
By John Huotari Leave a Comment

Image from the Fiscal Year 2019 Stockpile Stewardship and Management Plan of the U.S. Department of Energy’s National Nuclear Security Administration, which was released in October 2018.

The U.S. nuclear weapons stockpile continues to shrink and it’s gotten older, but the National Nuclear Security Administration, which has a site in Oak Ridge, has four modernization programs under way. That’s the busiest the NNSA has been since the Cold War era, Administrator Lisa Gordon-Hagerty said in a report to Congress in October.

The Y-12 National Security Complex in Oak Ridge, which enriched uranium for the first atomic bomb used in wartime, has been involved in the work to modernize some weapons and dismantle others as the stockpile changes.

The rest of this story, which you will find only on Oak Ridge Today, includes more information about Y-12’s work on nuclear weapons and a series of nine questions and answers with Hans M. Kristensen, the director of the Nuclear Information Project at Federation of American Scientists.
