Dear Mr. Chairman:
This letter provides the National Nuclear Security Administration (NNSA) and the Office of Environmental Management (EM) Listing of Hazard Category 3 Defense Nuclear Facilities with an Active Confinement Ventilation System consistent with Commitment 8.4 of the Department of Energy’s (DOE) Implementation Plan for Defense Nuclear Facilities Safety Board (DNFSB) 2004-2, Active Confinement Systems.
These listings were prepared at the sites, and were reviewed and approved by NNSA and EM line management and the Central Technical Authorities.
The next actions in the Implementation Plan require confinement ventilation system reviews in accordance with the Ventilation System Evaluation Guidance for Safety-Related and Non-Safety-Related Systems that was previously submitted as Deliverables 8.5.4 and 8.7. We are considering revising the review schedules that are established in the Implementation Plan. DOE will continue to work with your staff to coordinate this proposed revision and to complete the actions in the Implementation Plan.
If you have any questions, please contact me at (301) 903-0104.
