SUBJECT:

I & E Inspection Report 82-19

REFERENCE:

NRC Letter dated October 6, 1982 l

Dear Mr. Collins:

This letter is in response to the Notice of Violation received as a result of inspections conducted at Fort St. Vrain during the period August 9-13, and August 30-Sectember 3, 1932.

The following response to the items contained in the Notice of Violation is hereby submitted:

Functional Test Documentation of Safety-Related Chance Technical Specification 7.4.a.3 requires that

" Written procedures shall be established, implemented and maintained covering... test activities of safety related equipment."

Licensee Procedure Q-11, Issue 3 (December 29,1981),

" Test C cr.t ro l,"

requires, in Section 3.0e, that " Testing practices

. employed on safety-related items are required to assure that... test results are documented and evaluated to assure tes'. requirements have been satisfied."

Licensee Procedure 0-17, Issue 4 (January 13,1982), "Ouality Records," requires in Sections 4.2.3D and c,

that " Records providing objective evidence of conformance are required to

include, as appropriate,.. results of the inspection or test

.. dated signatures (s) of the person (s) verifying conformance or acceptability of evaluated test results."

Centrary to the above, there das n'o documentation of functional testing of the safety-related design change performed in CN 653.

l (1) The corrective steps which have been taken and the results

• achieved:

The licensees processing of CN's and CWP's was changed in August ISSO to give uniform treatment to FT documentation.

CN 653 did not receive the benefit of this aforementioned processing.

(2) Corrective steps which will be taken to avoid further violations:

Proper implementation of er.isting procedures for processing of CN's and CVP's.

(3) The date when full compliance will be achieved:

CN 653 was completed October 8,1981 and functionally tested via SR 5.4.9-A2 (copy attached),

on October 28, 1980.

Compliance was ac_ hieved as a result of the SR on October 28, 1980.

Should you have any further questions, please contact Mr. Edwin D. Hill, (303) 571-7436, ext. 201.

Connect a DVM to RIS-31193 TP-1 (+) and TP-0 (-).

11.

Put mode svitch to the TRIP ADJ position and adjust the TFlP RET to read 10.0 volts on the voltmeter. Check that the module reads 7

2 x 10 cp=, if not adjust METER ADJ until it does.

12.

Decrease TR** REF voh age to below 1 volt (reset ::1ps) and then increase the TRIP REF voltage.

Record the voltage levels at which the red light is lit "AS FOUND" in the table below.

Verify that the "AS FOUND" voltage at the trip meets the expected value.

If not adjust the trip point for RIS-31193 and record the "AS 2. EFT" voltage values.

14 Check the RIS meter indicator linearity by puttinS the module code switch to the TRIP ADJ position and using the TRIP REF. Record the voltage neces,sary to obtain the appropriate cps readings.
