Dear Mr. Chairman:
Enclosed is the revised Implementation Plan for Defense Nuclear Facilities Safety Board (DNFSB) Recommendation 2000-1 for stabilization, repackaging, or disposition of nuclear materials at Los Alamos National Laboratory.
The enclosed revision includes: (1) An improved risk ranking methodology that combines consequences with a probability of failure index (based on item age and reactivity) to rank each item according to risk; (2) A three-year acceleration in the stabilization of the non-weapons grade materials utilizing existing glove box capacity; (3) A revised commitment for the completion of stabilization and disposition of nine large vessels; and (4) Intermediate milestones for activities that represent progress in stabilizing, repackaging, and disposition of 2000-1 materials.
The National Nuclear Security Administration (NNSA) will review, approve, and control configuration of the baseline. In addition, the Department of Energy and NNSA are committed to ensuring that the proper resources and oversight are applied to support the stabilization project, and the commitments are accomplished on schedule.
Should you or your staff have any questions, please call Mr. Edwin Wilmot at (505) 667-5105 or Dr. Everet Beckner at (202) 586-2179.
