Dear Mr. St. Pierre:

The Nuclear Regulatory Commission (NRC) acknowledges the receipt of your June 9, 2006,response (Agencywide Documents Access and Management System (ADAMS) Accession No.

ML061640269) to Generic Letter (GL) 2006-03, "Potentially Nonconforming Hemyc and MT Fire Barrier Configurations."

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.
