Dear Mr. Chairman:
The purpose of this letter is to follow up on a commitment that we made to you in my letter of October 17, 2002, concerning the installation and testing of a seismic monitoring system for use in the Tritium Extraction Facility (TEF) currently under construction at the National Nuclear Security Administration’s Savannah River Site Office (SRSO). Westinghouse Savannah River Company (WSRC) has completed the installation and testing of a prototype seismic alarm system in Building 233-H, an existing Defense Programs facility at the SRSO. The seismic monitoring system installation and testing was accomplished in an existing facility in order to determine the optimum location, correct model of detector for this application, and the appropriate response from the “in-
facility” workers to the associated alarms. The WSRC report is enclosed for your information. The results of the testing of this system have been discussed with your staff during a TEF construction review that was held in December 2003.
The seismic monitoring system in Building 233-H has performed acceptably. This same system will be installed in the TEF as a portion of the worker protection system for this facility.
I would like to thank you and your staff for the continued interest in the TEF and look forward to maintaining our relationship during the completion of construction and the testing phase of this project. If we can be of further assistance, please contact me or have your staff contact Phil Pizzariello at (301) 903-7736.
