NOTICE OF VIOLATION' Houston O ghting & Power Company' ' Dockets: 50-498

. South Texas Project, Units-1 and 2 50-499 Operating Licenses: :NPF-76 n NPF-80

< During an NRC inspection' conducted'during the period June 7-30. 1989, a violation of NRC requirements was identified. The violation involved inadequate: procedures for abnormal operating conditions.: In accordance with the " General Statement 2, , of Policy and Procedure for NRC Enforcement Actions," 10 CFR' Part 2. Appendix C :

(1988),theviolationislistedbelow: >

Inadequate Abnormal Procedures Technical. Specification 6.8.1 requires, in part, that procedures shall be established-and implemented covering . . . a. the' applicable procedures recommended in Appendix A of Regulatory GCde 1.33. Revision 2 February 1978.

s Appendix A of Regulatory Guide 1.33, Sections 5 and 6, require, in part, that procedures for safety-related activities should be' established which address abnormal, off-normal, alarm, and emergency /other significant events / conditions.

South Texas Project FSAR,.Section 13.5.2, paragraph 3. "Off-Normal Operating Procedures," addresses this requirement by stating that necessary

. instructions / procedures for restoring an operating variable to its normal operating. condition will be-provided when the controlled value departs from the normal. range or following a perturbation which could degrade if proper

. :n action were not taken. A minimum list of plant off-normal operating procedures to.be prepared initially was provided-in the FSAR. The list.

included the following items:

Loss of~ automatic pressurizer control Malfunction of rod control system Turbine'lond rejection

. Contrary to the above.

1. Procedure OPOPO4-RP-0001, " Loss of Automatic Pressurizer Pressure ,

, ' Control," did not provide adequate guidance regarding the expected failure of a reactor protection pressere channel during low temperature-low pressure operations.

2. Procedures OPOP04-RP-0001 " Loss of Automatic Pressurizer Pressure Control," and OPOPO4-RP-0002, " Loss of Automatic Pressurizer Level Control," ~did not address the failure of a reactor protection channel (pressurizer pressure or level channels, respectively) if the failed channel'was not selected for the control function.
