ALBUQUERQUE OPERATIONS OFFICE

The Honorable John T. Conway
Chairman
Defense Nuclear Facilities Safety Board
625 Indiana Avenue, N.W., Suite 700
Washington, D.C. 20004

Dear Mr. Chairman:

Enclosed is the Los Alamos National Laboratory (LANL) Site Assessment Report that summarizes information developed from initial inspections and assessments of material containing uranium-233 at LANL. The report represents the deliverable for Commitment 4 of the Department of Energy's Implementation for addressing the Defense Nuclear Facilities Safety Board's Recommendation 97-1, concerning the safe storage of Uranium-233 material.

The report describes the types of uranium-233 material in inventory, the facilities where the material is located, and the actions completed to date to determine any remediation efforts needed as we work toward consolidating the material in preparation for movement to a long-term storage location. We will provide progress reports on these consolidation activities as necessary.

We have completed the actions identified under this milestone and propose closure of this commitment. If you have any questions, please contact me, or have your staff contact Steve Payne at (505) 845-6300.

Sincerely,

Bruce G. Twining
Manager
