Staff at Los Alamos and Sandia national laboratories welcomed the first hardware delivery for NNSA’s next generation supercomputer, called Trinity. Test beds for Trinity were delivered (two to Los Alamos and one to Sandia) as part of the New Mexico Alliance for Computing at Extreme Scale (ACES) collaboration.

Trinity came out of a partnership between the two laboratories, Cray Computers and Intel. The computer will have at least eight times greater applications performance than Cielo, the current NNSA supercomputer sited at Los Alamos and will be one of the most advanced computers in the world. Trinity will be sized to run the largest and most demanding simulations of stockpile stewardship, assuring the safety, security and effectiveness of the U.S. nuclear deterrent without the use of underground testing.

National Nuclear Security Administration (NNSA) announced today several impending key leadership changes that are expected to be phased in over the next several weeks.  

NNSA is re-establishing an Office of Policy to serve as a central resource for strategic planning and policy analysis. Steve Erhart, Manager of the NNSA Production Office (NPO), will head this new office.Steve has previously served as the Pantex Site Office Manager and the Pantex Site Office Senior Scientific and Technical Advisor. He has both the breadth of experience and the right professional attributes to assume this key integrating role in NNSA. 

Geoff Beausoleil, Sandia Field Office manager, will assume leadership for NPO. Geoff brings with him more than 30 years of experience, which includes Deputy Manager at the Pantex Site Office, Assistant Manager at DOE Idaho Operations Office, and Manager of the Sandia Field Office (SFO), where he has served since April 2012. Geoff’s experience puts him in an excellent position to manage NPO.

Jeff Harrell, Assistant Deputy Administrator (ADA) for the Office of Secure Transportation (OST), has agreed to accept the SFO Manager position. Jeff has been at OST since 2009 where he is responsible for ensuring the safe and secure delivery of nuclear weapon components and strategic nuclear material throughout the United States. His outstanding record at OST, following a distinguished 25-year military career, has prepared him to take on this larger role for NNSA. Kerry Clark will be the Acting ADA until a permanent selection can be made.

NNSA is extremely fortunate to have these accomplished leaders, and we commend them for their willingness to take on new career challenges and help our organization build broad based executive skills across our SES cadre.

NNSA BlogNorthwest Career and Technical Academy (NWCTA), a public magnet school in Las Vegas, recently won the Nevada Science Bowl. NWCTA did not lose a single match, defeating Reno High School in the finals. More than 30 teams from 29 schools from throughout Nevada, and from parts of California and Utah participated in the competition.

The Nevada Science Bowl is the premiere academic competition in the region. During fast paced matches, students “buzz-in” to answer exceptionally difficult questions covering science and mathematics.

The Northwest Career and Technical Academy team received $5000 for their school’s math/science departments, plus an all-expenses paid trip to Washington, D.C., for DOE’s National Science Bowl in April.

NNSA’s Nevada Site Office is the signature sponsor of Nevada Science Bowl. Nevada Science Bowl also receives donations from Northrop-Grumman, National Security Technology (NSTec), Navarro-Intera, Centerra, the Bureau of Reclamation, the National Atomic Testing Museum and VegasPBS.

NNSA BlogThis week, NNSA Principal Deputy Administrator Madelyn Creedon visited the Nevada National Security Site (NNSS). She discussed experiments that take place in the U1a complex. U1a is a complex 963 feet below the surface which is used for dynamic experiments with special nuclear material and other weapon materials.

Kristen Crawford, from Defense Experimentation and Stockpile Stewardship (DESS)/NSTec, described to Creedon how data from an experiment on detonators will be used in an upcoming subcritical experiment. After the detonation, probes track the movement of the surface of the detonator and show data on the screens. The data from the images is mathematically extracted to provide the velocity of the detonator surface as it moves. Los Alamos National Laboratory scientists take this data and use it to better understand surface velocities in dynamic experiments and to improve the conditional codes that help assure the safety and reliability of the nuclear stockpile without nuclear weapons testing.

NNSA BlogA Congressional delegation, comprised of Congressmen Mike Rogers, Rick Larsen, Doug Lamborn from the House Armed Services Committee, and Congressman Chuck Fleischmann of the House Appropriations Subcommittee on Energy and Water Development, visited the Naval Reactors Facility (NRF) at the Idaho National Laboratory (INL). The legislators were accompanied byDr. Elizabeth Sherwood-Randall, Deputy Secretary of Energy; Lt. Gen. Frank G. Klotz (ret.), DOE Under Secretary for Nuclear Security and NNSA Administrator; and Admiral John Richardson, Deputy Administrator, Office of Naval Reactors.

The group observed NRF processes at the Expended Core Facility (ECF). This facility is vital to national security, as it is the only location with the capability to receive, examine, and process naval spent nuclear fuel, necessary for the Naval Nuclear Propulsion Program to support continuous, day-to-day operations of the Navy’s nuclear powered fleet.

The 55-year-old ECF is maintained and operated in a safe and environmentally responsible manner, but the facility must be recapitalized to ensure continuous and efficient support of the fleet. It currently cannot support receipt of full-length aircraft carrier spent nuclear fuel, necessary to support the Navy’s refueling and defueling schedules for nuclear powered submarine and aircraft carriers. 

The delegation discussed the Spent Fuel Handling Recapitalization Project (SFHP), designed to recapitalize the spent fuel handling infrastructure at NRF for receipt, preparation, temporary storage, and packaging of naval spent nuclear fuel for secure dry storage and eventual shipment to a geologic repository. This project will retain the capabilities for naval spent nuclear fuel handling that currently exists in the ECF and its support facilities. The SFHP will help guarantee the operational availability of the nuclear fleet to fulfill military missions worldwide.

Additionally, the group received briefings on the Defense Nuclear Nonproliferation work conducted at INL. The lab provides facilities and capabilities that are vital to the nonproliferation mission.  The complex provides substantial resources and technical expertise to help achieve highly enriched uranium minimization both domestically and abroad and continues to play a critical role in DNN’s efforts to strengthen cyber security activities at nuclear facilities and installations. NNSA provides 23 percent of the total INL budget.

NNSA BlogIt’s amazing what can be accomplished when the government, contractors and academia come together for a great cause.

The Kansas City Engineering Zone, which officially opened last week, is a great example of community partnership to ensure urban students have a safe place and the resources to compete in the upcoming FIRST Robotics competition in March.

NNSA donated surplus machining equipment from the Bannister location to ensure high school students from Kansas City’s inner city schools have access to the equipment to participate in STEM activities, including FIRST Robotics.

KC EZ was pioneered by the KC STEM Alliance, a collaborative network of educators, business partners and affiliates that inspires interest in Science, Technology, Engineering and Math careers.

Consolidated Nuclear Security’s donation of $25,000 to the Helen Ross McNabb Center’s Veterans Housing Project served as one of the final building blocks in the $1.83-million effort to provide permanent housing to homeless veterans who have mental illnesses. Late last year, the ribbon was cut on the first apartment building, and the first four homeless veterans moved into their new homes in time to celebrate Christmas.

The CNS donation helped fund the newly constructed Cedar Crossing apartment building in Knoxville, Tenn., which provides eight one-bedroom units. The second phase of the project is rehabilitating a former apartment complex that will provide another 15 apartment homes.

CNS assumed responsibility for management and operations at the Pantex Plant and the Y-12 National Security Complex last summer.
