The Honorable A. J. Eggenberger
Defense Nuclear Facilities Safety Board
625 Indiana Avenue, N.W., Suite 700
Washington, DC 20004-2901
Dear Mr. Chairman:
I am writing this letter on behalf of Ambassador Brooks in response to your letter dated March 27, 2006. In your letter you forwarded results of your staff review of the Criticality Experiments Facility (CEF) Project design. Your staff review was focused on the adequacy of the authorization basis for CEF, the criticality safety program, the fire protection program, the confinement features, and the management and oversight roles of the National Nuclear Security Administration.
Major issues raised by the Board staff include inattention to the interface requirements between the existing Device Assembly Facility and proposed CEF operations, and lack of acceptable resolution of safety issues such as the need for fire protection, ventilation, and criticality alarms in the bays and cells.
I am pleased to inform you that all of the major issues brought to our attention by the Board staff have been fully deliberated and are resolved. Resolution of issues will be documented in the revision to the Preliminary Documented Safety Analysis and other relevant project documents. Issues that result in design changes will be implemented in the final project design.
The enclosure to this letter reflects planned disposition of major issues raised in the Board letter.
If you have any questions, please contact me or have your staff call Ms. Deborah D. Monette of the Nevada Site Office at (702) 295-2588.
