Dear Mr. Chairman:
The Department of Energy’s (DOE) Implementation Plan (IP) for Defense Nuclear Facilities Safety Board (DNFSB) Recommendation 2004-2, Active Confinement Systems, requires DOE to develop a methodology and issue guidance for systematically reviewing and assessing the confinement ventilation systems for many of its defense nuclear facilities. This guidance is deliverable 8.5.4, Safety Related Ventilation System Evaluation Guidance and deliverable 8.7, Non Safety Related Ventilation System Evaluation Guidance. These deliverables were due December 16, 2005 and December 15, 2005, respectively. By letter to you dated December 15, 2005, DOE indicated that the deliverables would be combined into one document and be provided by January 31, 2006. Enclosed is that guidance document, Ventilation System Evaluation Guidance for Safety-Related and Non-Safety-Related Systems.
We appreciate the involvement and input provided by your staff. If you or your staff have any questions, please contact me at 301-903-0104.
