LLNL 2The first four racks of NNSA’s Sequoia Supercomputer have arrived at Lawrence Livermore National Laboratory. Sequoia, a 20 petaflops (quadrillion floating operations per second) system based on BlueGene technology, will help continue to ensure the safety and reliability of the nation's aging nuclear deterrent. Sequoia will also help maintain U.S. leadership in high performance computing, promote scientific discovery and advance President Obama’s nuclear security agenda.

Deliveries of the system will continue through April 2012. Integration will take place in phases with final acceptance of the 96-rack system scheduled for September 2012.

By fall Sequoia is expected to be the most powerful supercomputer in the world and will be approximately twice as fast as today's most powerful system. To put this into perspective, if each of the 6.7 billion people on earth had a hand calculator and worked together on a calculation 24 hours per day, 365 days a year, it would take 320 years to do what Sequoia will do in one hour.




Robert “Dino” Herrera has been named acting deputy manager of the National Nuclear Security Administration’s Y-12 Site Office, replacing Dan Hoag who has been named Acting YSO manager. His assignment to YSO was effective Jan. 4, 2012.

Herrera has been a member of the Senior Executive Service since 2006 with managerial experience at NNSA Headquarters, Sandia Site Office, Los Alamos Site Office, and the Albuquerque Operations Office.

In his permanent assignment, Herrera serves as the deputy associate deputy administrator, Office of Infrastructure and Construction in Defense Programs. In this role, Herrera provides executive support to the Associate Deputy Administrator in directing the management of designated programs for the operations and maintenance of select NNSA facilities.

Before joining NNSA, Herrera was a resident engineer (head of construction office) with the U.S. Army Corps of Engineers (USACE). His USACE duty stations included King Khalid Military City, Saudi Arabia, and the Waste Isolation Pilot Plant, Carlsbad, N.M.



Ted Sherry
An appreciation party was held last night for Ted Sherry, who has retired as Site Office Manager for Y-12. Ted was recognized for his work at Y-12 and commitment to federal service. The event was sponsored by the East Tennessee Economic Council, the Energy, Technology and Environmental Business Association, and the Oak Ridge Chamber of Commerce.

Ted BowyerTed Bowyer, Pacific Northwest National Laboratory, has been elected as a fellow of the American Association for the Advancement of Science. Bowyer is an internationally recognized expert in nuclear nonproliferation and nuclear physics, specifically the detection of extremely low level airborne radioactive emissions that are definitive signatures for nuclear explosions.

At PNNL, he manages the Nuclear Explosion Monitoring and Policy program for NNSA’s Office of Nonproliferation Research and Development. In addition to performing fundamental and applied research in the development of systems to detect signs of proliferation, Bowyer has served as a scientific advisor on issues related to the Comprehensive Nuclear-Test-Ban Treaty Organization. He also has served as an advisor to the International Atomic Energy Agency, the U.S. State Department, National Academy of Sciences, and at the Conference on Disarmament.

Bowyer is a recipient of the Federal Laboratory Consortium Award for the design of the NNSA-funded Automated Radioxenon Sampler-Analyzer, which detects nuclear detonations by analyzing the atmosphere for traces of radioactive material that seeps from underground nuclear explosions.

Bowyer and others will be honored at a ceremony in February at the AAAS annual meeting in Vancouver, Canada.
