The Honorable A. J. Eggenberger
Chairman
Defense Nuclear Facilities
Safety Board
625 Indiana Avenue, N.W.
Suite 700
Washington, D.C. 20004-2941
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.
Sincerely,
Richard Black
Director
Office of Nuclear and Facility
Safety Policy
