Subject:
Beaver Valley Power Station, Unit No. 1 Docket No. 50-334, License No. DPR-66 Emergency Response Data System (ERDS)
The enclosed ERDS Data Point Library (DPL) changes are being submitted as required by 10 CFR 50, Appendix E, Section VI.3.a.
The changes have already been implemented on plant computers that provide data to the ERDS computer and consist of the following:
- 1. Intermediate Range Detector 1 Log Flux high alarm setpoint was changed from 8.OE-4 to 9.OE-4 amps (Mode 1)
- 2. Intermediate Range Detector 2 Log Flux high alarm setpoint was changed from 7.OE-4 to 7.4E-4 amps (Mode 1)
Previously, the reported values for these setpoints reflected plant operating Mode 1.
However, the plant computer at Beaver Valley 1 implements three different intermediate range detector high alarm setpoints corresponding to plant operating Modes 1, 2, and 3 through 6.
Alarm status data is provided to ERDS relative to the prevailing plant operating mode at the time the data is transmitted. Therefore, the attached DPL sheets have been revised to show all three setpoints for each detector, rather than the single Mode 1 setpoint previously reported.
The change described above includes a change that was made in April 2002, but not reported at that time. This omission has been entered in the FENOC corrective action system for evaluation and correction.
Beaver Valley Power Station, Unit No. 1 Emergency Response Data System (ERDS)
