RESPONSE
TO THE ERDS RULE,
- 10CFR50, APPENDIX E
Reference:
Letter G02-92-050, dated February 26, 1992, GC Sorensen (SS) to NRC, "Status of Response to ERDS Rule,
In the reference we stated that the Emergency
Response
Data System (EROS) for WNP-2 was completed and waiting for testing with the NRC once the FTS 2000 line was installed.
This line has been installed and the ERDS was successfully tested on May 19, 1992.
The rule requires that any hardware or software changes that affect the transmitted data points identified in the EROS Data Point Library must be submitted to the NRC within 30 days after the changes are completed.
Information on the WNP-2 Data Point Library has only been informally transmitted from the Supply System to the NRC.
To provide a firm base for this information we have discussed with Hr. John Jolicoeur of the Staff the benefit of using the computer printout of the library as developed by NUS as the base library from which we would notify the NRC of changes.
This appeared reasonable to Hr. Jolicoeur.
The printout has been obtained and reviewed for accuracy.
We have identified the need to revise the data for one parameter (STAB-CLASS1/CALC01).
This parameter is the reported stability class.
The changes reflect that the datum being
~provided is a digital value, i.e., the stability class, with a range from 1 to 7.
There has been no change for this parameter at WNP-2 but we previously responded to the survey as if the temperatures used to determine the stability class were being transmitted.

RESPONSE
TO THE ERDS RULE, 10CFR50, APPENDIX E The entire printout is attached to this letter with the above discussed changes for the reporting of the stability class noted.
We have taken the liberty of adding the Equipment Piece Number (EPN) that applies to each data sheet.
If the NRC were to add this information to the library it would assist in communicating with the NRC during use of the EROS as well as informing the NRC of design changes.
We have in place those procedure controls that are required to satisfy the 30 day notification requirement of the rule.
Sincerely, G.
