This review did not identify any significant untoward conditions.
The inspector noted the status of startup test packages and the test results report for the following systems:

Several test packages were selected for review.
The review of these test packages consisted of examination of the following documents:
TWG member comment form; yellow copy (comment resolution), test change notices, TWG review cover sheet, test results report, test procedure, test log, test exception log, master tracking system and discipline test schedule.
Significant problems, unresolved items and other issues are discussed below.
Gaseous Radwaste System 91PE-2GROl The test and complementary procedure MF310 ~ 1 (system flush) served to satisfy the test method of FSAR 14B.40.
The test verified operation of containment isolation valves, automatic operation of the waste gas system and ability to control the release of gaseous effluents.
Liquid Radwaste System 91PE2LROl;03;04 The test (LROl) served to verify that the liquid radwaste system tanks, pumps and ion exchangers operated in accordance with the design and demonstrated successful completion of tests described in FSAR section 14B49.3.1;2;3;4.
The test (LR03) served to verify that the concentrate monitor tank pumps, controls and interlocks operated in accordance with the design and was performed as described in FSAR section 14B49.3
~
This test revealed that the wrong size eductors were installed in tank 2N-LRN-T03A and T03B.
NCR SN-6127 has been written to cover replacement and retest of this item.
Test (LR 04) served to verify that the chemical drain tanks and pump operated in accordance with the design, that
'I
'I I'I
interlocks, lights and alarms functioned as required and that tests described in FSAR 14B49.3.1;3;4 were completed.
These tests packages demonstrate satisfactory completion of testing and operability of the liquid radwaste system.
Test 91PE2IR02 which covers the liquid radwaste evaporator has not been completed pending satisfactory evaluation of test results associated with the Unit 1 evaporator.
Modifications to the Unit 1 evaporator will also be made to the Unit 2 evaporator if test results are acceptable.
Fuel Building Ventilation 91PE-2HF01 This test served to verify proper operation of components, controls, alarms and also served to satisfy FSAR 14B21.3.2; 5 test descriptions.
FSAR test portions 14B.21.3.1;3;4 were satisfied by prerequisite testing.
The test satisfactorily demonstrated the system performs its intended function with one test exception related to pressure sensing.
An SFR (2HF-5165)
has been written to track this matter.
The following complementary tests were also examined; 91FB-OXX01; 91GT-OXX01; 91GT-OXX02; 91GT-OXX03) 91GT-OXX04) 91GT-OXX06) 91GT-OXX07) 91GT-OXX09; 91GT-OXXll.
These tests cover HVAC balancing, airflow and distribution, leakage and filter performance.
Containment Purge HVAC 91PE-2CPOl This test served to verify proper functioning of the power access and refueling purge air handling units and to verify isolation valve closure times are within limits.
Complementary tests as listed under HF were also used to cover the air cleaning portions of the system.
The test demonstrated operation of the containment purge system.
Three test.
exceptions remain open on this system.
These involve low air flow and a
flow switch problem and are being tracked by an NCR (SN6129).
Control Building HVAC 91PE-2HJOl This test served to demonstrate proper operation of components, controls, alarms and related portions of the control building HVAC system and to satisfy FSAR section 14B.23.3.1,5.
Complementary tests to satisfy 14B.23.3.2,3,4 are covered by generic tests as identified above under HF.
Fifty one test, exceptions were written during performance of this test procedure, test exception 47 remains'pen pending implementation of a DCP to change flow switches on the control building normal duct heater and test exception 49 regarding failure of a Slow switch in,the other duct heater.
'v
t l
Notwithstanding the above except'ions, the test;served to demonstrate satisfactory operation of the system.
'I The following generic test packages of filter and absorber system testing and flow balancing for the CP, HF and HJ systems Were ',examined.
These tests satisfy 14B.23.3.4, 14B.41.3.4 and 14B21.3.4.

.6 HF Duct Heater Performance Portions of this testing were performed by two contractors:
Nuclear Air Filtration Test Associates (NAFTA), Engineered Air Balance Company (EAB)
and witnessed by APS startup personnel.
The NRC inspector also witnessed portions of these tests.
Test 91GT-OXX01 for flow balance of CPN-J02 resulted in NCR-SM-6129.
Resolution of this item is discussed below in paragraph 4.
All other tests were completed and acceptance criteria satisfied.
No violations or deviations were id'entified.
Inde endent Effort Nonconformance report NCR-SM-6129 is identified in the test results report for 91PE 2CP01 and 91G70XX01.
Testing identified the inability of the containment power access (8") purge system to produce the design flow listed in the FSAR.
The licensee has dispositioned this NCR use-as-is at this time.
The inspector has requested a copy of the Bechtel Power Corporation evaluation supporting this decision.
The inspector stated to the licensee that they should carefully review the matter to evaluate the effect on occupational exposure and the ability to purge and enter containment quickly under degraded radiological conditions.
This matter will be followed until final resolution by the licensee (50-529/85-43-01).

Unit 1 as testing did not reveal this problem due to a poor test technique.
The inspector also discussed with cognizant staff, the licensee's plan to modify the containment purge system to permit, venting of containment to relieve.air pressure through the containment purge cleanup system at the intended design flow rate.
The licensee's planned solution for venting is acceptable.
I No violations or deviations were identified.'.
Exit Interview
)j An exit interview was held on November 20, 1984, the individuals denoted in paragraph 1 of this report'ere, present. "'he inspector 'discussed the scope and findings of the inspection at 'that time.
The licensee was offered the opportunity to propose"a schedule for,comple'tion'f non-technical specification monitors to, be incorporated'as a license condition or to provide a commitment t'o,complete the test program by same date.
The licensee declined to provide;either at the exit interview.
In a telephone conversation subsequent to'he'inspection on'November 21, 1985 between the licensee and,the Chief, Facilities Radiological Protection Section, USNRC, Region V,,'he matter was discussed further.
At this time the licensee indicated that due to procurement lead time for replacement parts, portions of the radiation monitoring system would not be completed until about June, 1986.
