>>> We request that members of the public also file a comment based on the JASON “Plutonium Report” summary, to: pitpeis@nnsa.doe.gov.
Attached, you will find is a supplementary comment filed into the draft Programmatic Environmental Impact Statement (PEIS) record. For legal and procedural reasons, this comment should be accepted though filed after the closure of the official comment period on July 16, 2026. This situation demonstrates that our request to extend the formal comment period for 30 days should have been granted and that this document and other requested documents should have been released well before the comment period ended.
In response to Freedom of Information Act (FOIA) requests and a threatened lawsuit, DOE’s National Nuclear Security Administration (NNSA) was forced to release a JASON group technical report “Executive Summary” on “Plutonium Aging” that does not support a rapid return to production of plutonium “pits” (weapons cores) for new nuclear warheads. This comment focuses on that new JASON report summary, which must be addressed in detail in the final PEIS.
