Initial Test Program
Dear Mr. Tedesco:
In our response to question 640.41 regarding instrument air pre-operational test, which we submitted to you on October 30, 1981, we committed to inform you as to the extent to which Perry will comply with items c8, c9, and cl0 of Regulatory Guide 1.80 (June 1974) by March 15, 1982. This letter and its attachment is submitted to provide such a response.
It is our intention to incorporate this response in a subsequent amendment to our Final Safety Analysis Report.
Very Truly Yours,
$+7 #

(14.2.12.1) us as to what extent you intend to comply with Regulatory Guide 1.80 for the instrument air preoperational test.
Provide a test description for the instrument air test.
Response
Clarification of the extent to which PNPP will comply with Regulatory Guide 1.80 is provided in revised Table 1.8-1.
The Safety Related Instrument Air System (P57) preoperational test description is provided in revised Section 14.2.12.1.48.
Testing of the Non-Safety Related Instrument Air System and the Non-Safety Related Instrument Air System Loss of Instrument Air Test will be accomplished according to the Acceptance Test Program discussed in Section 14.2.12.3.
A description of the Non-Safety Related Instrument Air System Acceptance Test and the Non-Safety Related Instrument Air System Loss of Instrument Air Acceptance Test are included.
NON-SAFETY RELATED INSTRUMEdT AIR ACCEPTANCE TEST a.
Test Objectives 1.
Verify the instrument air (IA) system is capable of supplying air at the required flow, pressure, temperature and dew point.
2.
Verify proper operation and control for the manual and automatic modes of operation of the IA compressor.
3.
Verify proper operation of redundant components.

NON-SAFETY RELATED INSTRUMENT AIR SYSTFM LOSS OF INSTRUMENT AIR ACCEPTANCE TEST
- n. Test Objective 1.
Upon sudden depressurization (simulated pipe break) of the instrument air supply verify that the air operated components fail from their normal operating position in a man"cr maintaining continued capability to provide system safety functions.
2.
Upon slow depressurization (simulated pipe plugging by freezing) of the instrument air supply verify that the air operated components fail frot their normal operating position in a manner maintaining continued capability to provide system safety functions.
- b. Prerequisites 1.
Instrument calibration and initial checkout and run-in testing is complete on pneumatic operated components to be tested.
l r
2.
The Instrument Air System and required support systems are available to I
supply instrument air to the components being tested.
I
- c. Test Procedure l
1.

2.
Position the components being tested in the test branch to their normal operating position and record position on data sheet.
Q&R 14.2-59
3.
Isolate the instrument air branch to be tested.
4.
a.
Rapidly depressurize the test branch and record the failed position of the components being tested.
b.
Monitor system responses and interaction and record any unexpected characteristics.
5.
After all the component's failed positions have been recorded, open the isolation valve to the test branch to re pressurize.
