Subject:

Docket Nos. 50-361 and 50-362 Emergency Response Data System-San Onofre Nuclear Generating Station Units 2 and 3

. Gentlemen:

l This letter is to inforrq the NRC of changes that have been made to the Emergency

. Response Data Syr,terc;s (ER.DS) at the San Onofre Nuclear Generating Station Units 2

' and 3.1As required by 10 CFR 50 Appendix E, Section VI.3.a, any hardware and software changes that affect the transmitted data points identified in the ERDS Data Point Library must be submitted to the NRC within 30 days after the changes are completed. Accordingly, revised pages to the ERDS Data Point Library are provided in the Enclosure to this letter.

A Unit 2 ERDS database point identification was revised from RT7813 to R78130CV,  ;

and a Unit 3 ERDS database point identification was revised from RT7813 to R7813OCV. These point identification changes and associated name descriptor  ;

changes are being made to reflect an update to the computer database for the l Radiation Monitoring Data Acquisition System. The analog radiation monitors are now routed to the ERDS database by this new computer system, and this new computer system has different point identification descriptor files (database numbering files).

.The ERDS database for these new descriptors is being revised to be compatible with

~

the new computer system.

' The above described Unit 2 and 3 changes for 2/3R7813 were completed on September 24,1999.
