Dear Mr. Chairman:
This letter is in response to the Board staff report received on March 28, 2005, concerning electrical and lightning protection systems at the Nevada Test Site. Enclosed is a memorandum from the Nevada Site Office (NSO) that forwards a response to issues at the Ula Complex, the Device Assembly Facility (DAF), G-Tunnel, site-wide lightning detection and protection, and the Radioactive Waste Management Complex (RWMC). Also included with the package are (1) an Implementation Plan that provides information to set overall disposition finding priorities, including G-Tunnel and (2) an analysis of historical data for site-wide lightning detection and protection to confirm existing alert distances, as requested by the Board staff report. NSO will also address the issue of lightning protection during transport operations within the G-Tunnel.
If you have any questions please contact me or have your staff contact Mike Thompson at 301-903-5648.
Thomas P. D’Agostino
Acting Deputy Administrator
for Defense Programs
(Note: Please call Mike Thompson at 301-903-5648 for a copy of this enclosure.)
