TMI Item II.K.3.25 - Effect of Loss of AC Power on Pump Seals The applicant has reported that the reactor coolant pumps would not lose function (due to loss of seal cooling) following a loss of AC electrical power lasting up to two hours. This information is documented in the applicant's FSAR and the nuclear steam supplier's CESSAR.
In addition, the normal cooling water supply to the pump seals is backed up by the essential cooling water system.
On loss of AC power, the essential cooling water system is designed to be automatically powered from Class IE redundant power supplies.
The findings of this review are considered to be consistent with the provisions of Section II.K.3.25 of NUREG 0737.
No items of noncompliance or deviations were identified.
3.
TMI Item II.E.4.1 - Dedicated Hydrogen Penetrations The applicant has provided redundant dedicated penetrations for hydrogen control.
Through direct visual observation it was confirmed that penetrations U35 and U36 are equipped with two inch recombiner supply lines and penetrations U38 and U39 are equipped with two inch recombiner discharge lines.
The findings of this review are considered consistent with the provisions of Section II.E.4.1 of NUREG 0737.
No items of noncompliance or deviations were identifie _ _ _ _ _ - _ _ _ _ _ _ -.

Startup Testing Program a.
Prerequisite Testing PM Program A review of the Bechtel preventive maintenance program confirmed that actions were being taken to maintain equipment which had been turned over to the Bechtel startup organization by construc-tion.
These activities are described, in part, in administrative control procedures.
The program includes the identification of equipment requiring preventive maintenance, check sheets identifying needed maintenance, schedules defining frequencies of maintenance and reviews of completed work.
The system is maintained manually; however this does not appear to present a problem since the release of subsystems to APS operations for testing (responsibility for maintenance is also transferred)
is expected to take place throughout this year.
b.
Plant Annur.ciator Preoperational Test This is the first of the major preoperational tests to be initiated.
The inspector observed that an approved procedure was being used.
It was found by the testing personnel that minor changes to the test procedure were required and these changes were made in accordance with procedure change instruc-tions.
The testing staff on shift consisted of a Level III test director, a Level II test coordinator, a startup engineer and supporting operating personnel. Test information was
}
recorded as required, prerequisite conditions were signed off, and test logs were being maintained.
c.
Plant Instrumentation Calibration The inspector was informed by the APS QA staff that some NSSS instrument calibrations had been performed using vendor specifi-cations which were not current.
The cause of the problem is under review, but it may be related to the use of a listing of vendor specifications obtained from Bechtel engineering which had not been updated to include the most recent specification revisions.
The problem was identified when I/C technicians could not perform calibration of some instruments because of the inappropriate instrument ranges stated in the specifications.
The completed calibrations will be evaluated to determine the extent of recalibration necessary.
The applicant is reviewing the reportability of this matter to the NRC.

Plant Tour Several tours of the plant were made during the period.
The inspector confirmed that a list of personnel authorized to request equipment clearances was available to the operating staff.
l
'
The inspector also reviewed several clearances'and determined that they had been performed in accordance with applicable procedures.
'Several instances were observed where jurisdictional tags incorrectly indicated systems had been released to APS operations.
Upon being i
informed of these findings by the inspector, those items were l
corrected by Bechtel.
Several instances of disassembled equipment were observed to have been formally authorized by the Bechtel startup organization.
Housekeeping continues to warrant additional attention as systems are prepared for testing.
No items of noncompliance or deviations were identified.
6.
Exit Meeting An Exit Meeting was held with Messrs. Van Brunt and Har' ley and their staffs on February 12, 1981.
At this time the fir.c igs of the inspection were discussed. The commitment by APS to resolve the problem relating to recalibration of plant instruments was highlighted.
