Thank you- for your letter of August 17,1984,'in response to our letter and

the attached Notice of Violation dated July. 18, 1984. ~ As a result of our

review,- we find that additional.information:is needed as discussed with your

-Mr. R.' E. Camp on. September-24, 1984.:

~

Specifically, the preventive action taken to assure proper indication of -

'

' installed instrumentation when~used for certified test data appears.unlikely.

to provide that assurance. Your letter refers to a change to CP-SAP-7,

" Format and' Content of Test Instructions / Procedures." - Upon reviuing the

August- 15, 1984,Li nterim change to Section 4.3.3.6.h of CP-S.af-7,'we are

.

concerned that the added note does not direct the' procedure writer lto '

include a prerequisite or test step which ensures that installed instrumen-

Ltation (whether previously in service or.not)'is filled and vented just

prior to obtaining preoperational test data. Instead the change-_ suggests e

that.the writer consider such a. provision, and then only where the proposed

preoperational'or acceptance test procedure.. places the system in service

< vice the'" System Operating Procedure."- Whether or not the preoperational1

test places the system in service is not'germaine to the problem. Also, ' <

whether the system has been in or_ out of service before the test-has little-

piping.' The interim change to CP-SAP-7 does not appear to provide, reasonable

assurance that-differential pressure-detectors will provide reliable' data

~

because'it.does not require the. test procedure to contain provisions for-

, filling and venting such detectors before data'are obtained.- Unless this .

assurance is provided, Criterion XI and XII of 10 CFR 50, Appendix,B would not

'In light of the above concern, your response to-Notice of Violation

445/8421-02 is inadequate with respect to " preventive action." <
