Chu tools

NNSA has approved a special tooling system designed to improve the processing time of the B83. The tools were created by NNSA’s Pantex Plant and announced last fall. See press release here.

The tooling system for the B83 program is now part of NNSA’s Seamless Safety for the 21st Century (SS-21) process. The SS-21 process fully integrates the weapon system with the facility, tooling, operating procedures and personnel involved in the dismantlement program to form a safe, efficient and effective operating environment. The SS-21 process has been incorporated into all current Pantex weapon programs.

Approval for the special tooling system took a few months longer than originally expected because of the rigorous approval process. Final tools were delivered and the Hazard Analysis Report was published and approved by Pantex Site Office. In addition, the Nuclear Explosive Safety Study was conducted with no pre-start findings.

The goal of the project was to streamline the B83 disassembly and inspection and dismantlement processes. The new tooling process is designed to have multi–purpose functions, which includes the ability to support future B83 assembly operations.

The tooling system supports a safe, secure and effective strategic deterrent and is being used to support stockpile surveillance and dismantlement work. The new tooling system will be used to support the upcoming concurrent retrofit of the Gas Transfer System and Neutron Generators (ALT 353/753 respectively), scheduled for first production to occur in July 2014.

The B83 program team includes members from Lawrence Livermore National Laboratory, Pantex Plant and Sandia National Laboratories.

Anton Tran

Anton Tran, from NNSA’s Office of Nuclear Weapon Surety and Quality, has received this year's General Charles A. Horner Award from the Air War College. Tran received the honor for his paper, titled "An American Vital Interest: Preserving the Nuclear Enterprise Supplier Base.” The paper studies the impact of an eroding supplier base on the nuclear security enterprise's ability to adequately sustain the nuclear weapon stockpile, upon which the United States national security strategy and defense posture rely. The paper identifies current supplier base challenges, evaluates case studies from other industries, explores and examines potential solutions and offers recommendations.

The General Charles A. Horner Award is presented by the Air Force Counterproliferation Center each year to an Air War College student for the best study of an issue of most immediate and important utility to the US counterproliferation program.

Following his graduation from Air War College on May 28, 2012, Tran will return to Albuquerque, N.M., and be reassigned to NNSA’s Office of Nuclear Weapon Stockpile.

Employees, family and friends of the Y-12 National Security Complex fanned out across the region recently to help nonprofit agencies in a variety of ways – painting, landscaping, building and repairing, stocking food and school supplies, and much more.

With more than 1,100 participants – including employees, their family members and other volunteers recruited by Y-12 employees – working some 60 projects, this year marks the largest turnout in the ten years of the program.

The work took place primarily over the weekend, with some projects scheduled on other dates, and all of the projects benefit local individuals and organizations due to the generosity and dedication of the volunteers.

Projects this year included making quilts for NHC Health Care, loading boxes of food at the Valley View Mobile Pantry and at Second Harvest, painting rooms at the Scarboro Learning Center, building a sidewalk at Lenoir City’s North Middle School, and washing dogs for the Shelter Animals Rescue Group.

Erhart Will

Pantex honored employees for their military service May 16 with a flag ceremony and luncheon. The annual Armed Forces Day Celebration included the unveiling of the Wall of Heroes, which depicts Pantexans actively serving or who have served in Operations Enduring Freedom, Iraqi Freedom and Noble Eagle. 

There are approximately 900 veterans among the Pantex workforce. Recognized at the event was Pantex Senior Project Manager and U.S. Navy Seabee Capt. David Will, who is just three weeks back from his nine-month deployment in Afghanistan – his third tour of duty in six years.

“I believe we are blessed to have the jobs we have and to do the work we do here at Pantex – to serve our country. It’s a blessing to serve,” said Steve Erhart, NNSA Production Office Manager. “But blessing requires sacrifice….someone, somewhere always sacrifices something so that blessings can occur. It’s selflessness instead of selfishness. Our nation’s service men and women all sacrifice their freedom to ensure ours. Their willingness to make the ultimate sacrifice for our freedom is at the heart of the blessings we all enjoy.”

The Pantex Fire Department Honor Guard conducted the flag-raising ceremony, and the event featured speakers from both the Pantex Site Office and B&W Pantex, including guest speaker retired Navy Capt. and Supply Chain Management Division Manager Mike Tryon.

Bren Tower

A world record will be set at the Nevada National Security Site (NNSS) on Wednesday, May 23, when a 1,527-foot tower used in above-ground nuclear experiments in the 1960s will be brought down in a planned demolition.

The BREN (Bare Reactor Experiment -- Nevada) Tower will be the tallest structure of its kind ever to be demolished. The tower is  taller than the Empire State Building (1,454 feet, to the top of lightening rod), taller that the Stratosphere Tower in Las Vegas (1,148 feet) and half-again as tall as the Eiffel Tower (1,063 feet, with antenna).

The tower will be brought down due to safety concerns for personnel working nearby and risk to aircraft flying in the area. Contributing factors include lack of use, maintenance issues, and an uneconomical cost of more than $1 million that would have been required return the tower to a usable state.

DEMCO, Inc. is partnering with Controlled Demolition, Inc. to bring down BREN Tower in a safe, environmentally friendly manner. Because the tower is very tall, highly controlled demolition techniques will be employed. The tower will be demolished by explosively removing a small section of one leg at ground level, then explosively severing the tensioned guy wires and the anchor/stanchions on the opposite side.

Two devices that delay passage to controlled-access areas at Y-12 recently received significant developmental boosts. The Access Rate Control System (ARCS) and the Delayed Latching Mechanism (DLM) were licensed in February by Knoxville start-up Sustainable Environment Technologies, LLC (SET). About five weeks later, Y-12 and the licensee signed a Cooperative Research and Development Agreement (CRADA).

The ARCS is a kit designed for installation on existing or new full-height turnstiles. It generates resistance and slows entry if someone enters at faster-than-normal speed. The DLM slows unlatching of gates and doors from the outside, requiring a sequence of actions to retract the latch and giving security personnel time to prevent the door or gate from opening if necessary.

Y-12 President and General Manager Darrel Kohlhorst voiced support to SET President Dan Hurst, said, “Once we know that something we have invented works, we want to make it possible for someone else to use it. It’s our job not only to facilitate a license but also to work with the licensee to get it off the ground. If we are using these devices, there is no reason they are not at every one of the NNSA sites.”

Anticipated markets include other U.S. Department of Energy facilities, commercial nuclear facilities, pharmaceutical manufacturers, correctional facilities, and large sporting venues. Both devices were invented by senior technical advisor and National Security Technology Center director Lee Bzorgi, whom Popular Science magazine has called “DOE’s Gadget Guru” because of his numerous inventions.

How can government partner with the private sector to control sensitive nuclear technology without blocking legitimate commerce? How could social media be used to target information-driven arms control and nonproliferation? How are nuclear disarmament dynamics shifting?

These were just a few of the intriguing topics that 90 participants tackled at a nuclear security forum on April 18-19. The event, attended by representatives from seven countries, was part of the Project on Nuclear Issues (PONI), an activity of the Center for Strategic and International Studies (CSIS). CSIS was recently ranked the world’s top security and international affairs “think tank” by a well-respected annual assessment from the University of Pennsylvania. 

Rising experts in the nuclear security field presented research findings on nuclear weapons issues and shared information in interactive forums. Speakers covered work that was funded by NNSA and other agencies. Graduate students from 12 universities also participated, advancing a PONI goal of building a networked community of young nuclear experts. Warren Stern, Director of the Domestic Nuclear Detection Office at the U.S. Department of Homeland Security, provided keynote remarks at the meeting.

This year’s event was held at Pacific Northwest National Laboratory and DOE’s Volpentest HAMMER Training and Education Center. During tours, participants experienced an up-close-and-personal view of technologies and facilities to counter nuclear terrorism, prevent proliferation, and verify arms control regimes.
