Gulf States Utilities Docket: 50-458  !

River Bend Station 0perating License: NPF-47 r i

During an NRC inspection conducted on February 16 through March 31, 1988, a i violation of NRC requirements was. identified. The violation involved an  ;

inadequate alarm response procedure. -In accordance with the "General Statement of Policy and Procedure for NRC Enforcement Actions," 10 CFR Part 2, Appendix C (1987), the violation is listed below:

Inadequate Alarm Response Procedure  !

River Bend Station Technical Specifications, paragraph 6.8.1.a. requires  !

that procedures for activities identified in Appendix A of Regulatory Guide 1.33, Revision 2, February 1987 be established, implemented and  !

maintained. Paragraph 5 to Regulatory Guide 1.33 requires that alarm J. annunciator procedures "contain: (1) the meaning of the annunciator, .

(2) the source of the signal, (3) the immediate action that is to occur automatically, (4) the immediate operator action and (5) the long-range j actions." i Contrary to the above, it was discovered on March 10, 1988, that the source of the signals defined in alarm response procedure ARP-601-19,  !

"P601-19 Alarm Responses," Revision 2, were incorrect in that the alarm '

setpoints were incorrectly stated for alarm numbers 2403 and 2409. These alarms are for main steam tunnel ambient temperature high and main steam tunnel ventilation differential temperature high. In addition, the immediate and long range actions were inadequate in that actions for ,

alarm 2403 defined the temperature at which the main steam tunnel  :

temperature should be maintained below as 180 F rather than the correct value of 130 F. If cooling systems cannot prevent the temperature from .

approaching the main steam valve isolation setpoints, no additional '

operator actions were specified to prevent a full main steam line [

isolation at high reactor power levels. ,

This is a Severity Level IV violation. (Supplement I) (458/8808-01) ,

Pursuant to the provisions of 10 CFR 2.201, Gulf States Utilities is hereby h required to submit to this office within 30 days of the date of the letter ,

transmitting this Notice, a written statement or explanation in reply, '
