Don Cook, NNSA’s deputy administrator for Defense Programs, last week spoke to Pantexans about the future mission of Pantex and the critical role the plant will play in maintaining the nation’s stockpile for decades to come. During the visit, Cook congratulated some of the 100-plus Pantexans who helped to secure the plant and conduct recovery operations during and after the Feb. 25 blizzard that dropped more than 19 inches on the Amarillo area.
Workers at the Pantex Plant last month finished the largest concrete pour to date on the High Explosives Pressing Facility, completing the last of the elevated soffits, which are part of the roof deck/second story of the building.
The pour marked the completion of approximately 50 percent of the construction on the 45,000 square-foot facility, which will combine high explosives operations from numerous outdated buildings into one state-of-the-art facility which will help to bolster Pantex’s status as the DOE’s High Explosives Center of Excellence for HE manufacturing.
Construction of the $65 million facility is expected to be complete next year. The construction effort is being managed by the U.S Army Corps of Engineers and the design effort/plant support is being led by B&W Pantex/CH2MHill.
Lawrence Livermore National Laboratory researchers have performed record simulations using all 1,572,864 cores of Sequoia, the largest supercomputer in the world.
The simulations are the largest particle-in-cell (PIC) code simulations by number of cores ever performed. PIC simulations are used extensively in plasma physics to model the motion of the charged particles, and the electromagnetic interactions between them, that make up ionized matter.
Sequoia, a NNSA machine, is based on IBM BlueGene/Q architecture and is the first machine to exceed one million computational cores. It is also second on the list of the world’s fastest supercomputers, operating at 16.3 petaflops (16.3 quadrillion floating point operations per second). Sequoia preparing to move to classified computing in support of stockpile stewardship.
About the photo: OSIRIS simulation on Sequoia of the interaction of a fast-ignition-scale laser with a dense DT plasma. The laser field is shown in green, the blue arrows illustrate the magnetic field lines at the plasma interface and the red/yellow spheres are the laser-accelerated electrons that will heat and ignite the fuel.
The NIF Warehouse Group recently marked the 15th year without a lost work-time injury. Since warehouse operations began in 1998 at an off-site facility, the group has been involved in the receipt, storage and/or delivery of virtually every component that has gone into the construction of NIF, installation of the laser systems and the conduct of the National Ignition Campaign.
A celebration was held on March 6 at Lawrence Livermore National Laboratory to recognize the group’s impressive accomplishments in both safety and productivity.
