The National Nuclear Security Administration (NNSA) has determined that construction and operation of a new East End Campus at the Y-12 National Security Complex will not significantly affect the quality of the human environment. This finding clears the way for the project to move forward without preparing a full environmental impact statement. NNSA issued a […]

According to UCS, the document is an unclassified summary of a recent JASON study – a publicity-averse scientific advisory board for the U.S. military – examining the aging of plutonium in the U.S. nuclear stockpile. The organization said the summary was marked unclassified but was nevertheless entirely redacted by NNSA before being released under FOIA. […]

The National Nuclear Security Administration (NNSA) has authorized startup of the Calciner Project at Y-12 National Security Complex, adding another modernized uranium processing capability. The calciner converts uranium-bearing liquid solutions from pipes and process equipment into a stable solid form for storage, allowing radioactive material to be removed from legacy facilities and supporting the eventual […]

A new study by Princeton University researchers argues that the National Nuclear Security Administration’s analysis underestimates the geographic and health impacts of any potential severe plutonium fire at pit production facilities. The peer-reviewed study, published in Science & Global Security, examines hypothetical plutonium fire scenarios at Los Alamos National Laboratory in New Mexico and the […]

A Government Accountability Office (GAO) report released Wednesday found the National Nuclear Security Administration (NNSA) has not fully assessed the workforce and programmatic resources needed to support planned investments in the scientific infrastructure underpinning U.S. stockpile stewardship. The report recommends that NNSA conduct a comprehensive assessment of its long-term science, technology and engineering workforce and […]

Mission Support and Test Services (MSTS), prime contractor for the National Nuclear Security Administration’s (NNSA) Nevada National Security Site (NNSS), issued a request for information and expression of interest to help develop procurement strategy for fire suppression system services. The pre-solicitation notice seeks industry feedback to help shape a future contract supporting the full life […]
