Dear Mr. Chairman:
On July 12, 2006, Secretary Bodman submitted the Department’s revised Implementation Plan for Defense Nuclear Facilities Safety Board Recommendation 2004-2, Active Confinement Systems. Commitment 8.6, Safety Related Ventilation System Evaluation, of the Implementation Plan (IP) states that the evaluation process will be piloted at several facilities. For the National Nuclear Security Administration (NNSA), the Pit Disassembly and Conversion Facility (PDCF) has been identified as a pilot facility. The PDCF Ventilation System Evaluation Report is enclosed. The report has been reviewed by the NNSA Central Technical Authority’s Chief of Defense Nuclear Safety (CDNS) and the 2004-2 Independent Review Panel (IRP). The CDNS and IRP have concluded that the evaluation and its results are technically sound, consistent with Department of Energy/NNSA safety policy and goals, and consistent with the intent of the IP.
If you have any questions concerning the report, please contact me or have your staff contact Rick Kendall by phone at (301) 903-3102 or by e-mail at Rick.Kendall@nnsa.doe.gov.
