NNSA announced that it recently completed two milestones towards production of early plutonium oxide feedstock for its Mixed Oxide (MOX) Fuel Fabrication Facility. In its second year in production, NNSA exceeded the FY 2012 goal of 200 kilograms of plutonium oxide production by disassembling nuclear weapons pits and converting them into plutonium oxide at Los Alamos National Laboratory (LANL). NNSA also initiated operations at H-Canyon and HB-Line at the Savannah River Site (SRS) to begin plutonium oxide production. The oxide production at both LANL and SRS provides the initial feedstock for the MOX facility and demonstrates the first steps towards permanent plutonium disposition.

NNSA’s Sequoia supercomputer, housed at Lawrence Livermore National Laboratory, is ready to shake out and fully develop its capabilities required to fulfill its national security missions, starting early next year.
NNSA reached an important transformation milestone today with the successful on-time, on-budget occupancy transfer of the LEED Gold National Security Campus in Kansas City, Missouri. As the first step in moving out of a Cold War-era complex, NNSA will start paying the lease on the green manufacturing facility under a unique private/governmental partnership.

Jolie A. Cizewski of Rutgers University has been selected as the Woman Physicist of the Month for November by the American Physical Society (APS). She is the director of NNSA’s Stewardship Science Academic Alliance (SSAA) Center of Excellence for Radioactive Ion Beam Studies for Stewardship Science and has served in that capacity since 2003. The Center conducts leading-edge nuclear physics research using short-lived nuclei produced at Oak Ridge National Laboratory, Argonne National Laboratory, Michigan State University and elsewhere.
In this photo, Jolie A. Cizewski and her former postdoc Nick Fotiades who is currently a LANL staff member check out the GEANIE array of Compton suppressed Ge detectors at The Los Alamos Neutron Science Center (LANSCE).
In its ongoing support of science, technology, engineering and mathematics (STEM) education, Y-12 recently awarded a total of $5,000 in scholarships to Roane State Community College freshmen Wes Jenkins and Sara Lemmonds.
