6 NOTICE OF VIOLATION American Electric Power Docket No. 50-315 Service Corporation As a result of the inspection conducted on July 7 through 11, 1986, and in accordance with the General Policy and Procedures for NRC Enforcement Actions (10 CFR Part 2, Appendix C), the following violation was identified:

Unit 1, Technical Specification 3.3.2.1, specifies that the Engineered Safety Feature Actuation System instrumentation channels shall be response-timed as shown in Table 3.3-5. TS Table 3.3-5 requires that the turbine trip reactor trip ESF activation on steam generator high-high water level have an overall response time of less than or equal to 2.5 seconds. TS definition 1.23,

" Engineered Safety Feature Response Time," states in part that the response time "shall be that time interval from when the monitored parameter exceeds its ESF actuation setpoint at the channel sensor until the ESF equipment is capable of performing its safety function."

Contrary to the above, prior to July 10, 1986, the licensee did not adequately response time test the Unit 1 steam generator water level high-high level turbine trip reactor trip, in that, response time was not measured through the turbine trip logic (i.e., the licensee did not fully test the time interval from the channel sensor to the ESF equipment).

The licensee demonstrated that the overall response time, was less than TS Table 3.3-5 requirement of 2.5 seconds on July 10, 1986.

This is a Severity Level IV violation (Supplement I).

Pursuant to the provisions of 10 CFR 2.201, you are required to submit to this office within thirty days of the date of this Notice a written statement or explanation in reply, including for each violation: (1) The corrective action taken and the results achieved; (2) the corrective action to be taken to avoid l further violations; and (3) the date when full compliance will be achieved.

l Consideration may be given to extending your response time for good cause shown.
