Dear Mr. Kasdorf:
This letter is in response to your January 16, 2009, letters to me which contained the Finding Forms documenting the Defense Nuclear Facilities Safety Board's issues on the following two topics:
1. Safety Significant Active Ventilation System
2. Seismic Characterization and Seismic Design
As you requested, we have completed these forms and have attached them to this letter with the applicable supporting documentation.
We look forward to continuing to work with you during your review of the design of the Chemistry and Metallurgy Research Replacement Facility (CMRR) design needed to support the Board's CMRR Certification to Congress as specified in Section 3 112 of the Duncan Hunter National Defense Authorization Act for Fiscal Year 2009.
If you have any questions, please contact me or have your staff contact Patrick Rhoads (202) 586-7859.
Sincerely,
Gerald
