Dear Commissioners and Staff:
As requested by NRC's letter requesting supplemental data dated September 20, 1999, and clarification from ERDS Project Officer, Mr. John Jolicoeur, per teleconference on October 7, 1999, this supplement to Special Report 99-05 is submitted to provide additional information regarding data points provided via PG&E Letter DCL-99-086, dated June 18, 1999.
The ERDS system was installed as documented in PG&E Letter No. DCL-91-261, "Emergency Response Data System Implementation Plan," dated October 25, 1991. The Safety Parameter Display System (SPDS) system was installed in response to NUREG-0737, Action Plan Item I.D.2, and NUREG-0696 (circa 1980). PG&E upgraded the SPDS computer system during 1996 (reference DCL-98-136, "10 CFR 50.59 Report of Facility Changes, Tests, and Experiments for the Report Period May 24, 1996 March 28, 1998"). The upgraded SPDS is Y2K compliant and has been further enhanced to provide the ERDS function. PG&E has enhanced the data points requested in NUREG-1394, Revision 1, dated May 1991, with clarification provided by the ERDS Project Officer, as "ERDS Data Point Library, Revision 2," enclosed.
