Dear Mr. Crane:
The Nuclear Regulatory Commission (NRC) acknowledges the receipt of your June 6, 2006, response to Generic Letter (GL) 2006-03, Potentially Nonconforming Hemyc and MT Fire Barrier Configurations for the Dresden Nuclear Power Station, Units 2 and 3 (Dresden). Under oath or affirmation, you stated that Dresden does not rely on either the Hemyc or MT fire barrier system and provided documentation with regard to other 1 or 3-hour fire barrier material that separates redundant safe shutdown trains. These trains are located within the same fire area, and are designed and installed in accordance with current NRC guidance. Based on your response, the basis for stating that this other fire barrier has been designed and installed in accordance with NRC guidance should be maintained on site, and will be subject to inspection during the normal NRC inspection process. The NRC staffs review of your response to GL 2006-03 is complete.

Sincerely,
/RA/
