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…]

Y-12 facilities could be crucial in plan to replace W78 warhead

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…]

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.

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

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…]
