Subject:

Docket Nos. 50-361 and 50-362 Emergency Response Data System Data Point Library Reference File San Onofre Nuclear Generating Station, Units 2&3

Reference:

1.

Generic Letter 89-15. " Emergency Response Data System."

2.

Letter R. M. Rosenblum (SCE) to NRC, ~ Emergency Response Data System Implementation, dated September 10, 1992.

The purpose of this letter is to inform you of the completion of the Emergency Response Data System (ERDS) installation. The testing of the ERDS data transmission to the NRC was successfully completed on January 6, 1993.

Two software changes were made during the testing:

1.

Data Base Change This item is in response to an NRC request for a minor change to the database. The change was made by a Field Interim Design Change Notice (J-4634) immediately prior to the testing. The revised pages are included (Enclosures 1 and 2). An unofficial copy was telecopied to Mr.

J. R. Jolicoeur (NRC) to enable the NRC to create the software database file change. The enclosures will update, on a replacement page basis, the information SCE previously provided to the NRC (Reference 2).

2.

Sign-On/ Sign-Off Protocol The second item is to provide the NRC with notification of a change in the asynchronous flow control implementation for ERDS communication protocol. The original design for the remote (SONGS) ERDS system n

4400,19 utilized x0N/x0FF flow control for communicate between systems.

However, it.was detennined through NRC/SCE testing that the application level flow control, SUSPEND / RESUME, as specified in NRC-317 Revision'1, should be used since the CODEX modems did not respond properly to XON/X0FF flow control. The NRC contractor for the testing, Lynne Saul, requested SCE formally notify the NRC of this change so the NRC database

[Oh h 9302250188 930219 PDR ADOCK 05000361 F

PDR i *\\

l-Document Control Desk' could be revised accordingly. Please ensure your computer system reflects the change in the flow control usage.

This letter provides the formal notification requested..

e This closes out all remaining commitments concerning the Emergency Response Data System.

If there are any questions, please call me.

Sincerely, I
