Licensee Action on Previous Ins ection Findin s a 0 (Closed)
Unresolved Item (387/78-16-02):
Incomplete Material Specifications The licensee has developed and is implementing a program to review all suppliers quality documentation prior to system turnover.
This review is being conducted in accordance with Field Procedure FP-G-21, Revision 0.
Documentation Review Record Serial No.
1643 includes the lack of the hardness test results for the 90'lbow in pipe spool DCA-110-2"4.
The material certification for the E 308-16 filler metal heat No.
740654A does not include the results of fillet weld tests because this test is optional in accordance with SFA 5.4 and not required by ASME Section III Article NB-2400.
The inspector had no further ques-tions on this matter at this tim (Closed)
Unresolved Item (387/78-16-04):
Indications in recircula-tion system safe end welds'.
(Note:
This item was incorrectly iden-tified as 78-16-03 in the original report.)
Subsequent to the preservice inspection of the N2 nozzle safe ends the licensee committed to replace the recirculation system inlet nozzle safe ends and thermal sleeves.
PP8L letter PLA-350, dated May 4, 1979, documents the modifications.'he modification requires the removal of the nozzle safe ends and the safe end to safe end extension weld in question.
The ten Unit 1 safe ends have been removed.
The modified safe end design does not incorporate a safe
.
end extension.
The licensee has contracted to destructively examine a safe end to safe end extension weld to verify the ultrsonic test-ing conducted during preservice inspection.
The inspector had no further questions on this matter at this time.
(Closed) Unresolved Item (387/79-04-02):
Containment Liner Plate Melding The licensee has issued Field Procedure FP-M-l, Revision 6 which incorporates controls for the inspection of welding on the contain-ment liner plate.
The revised procedure requires that guality Con-trol Personnel be notified prior to welding attachments to or remov-ing attachments from the liner plate.
The procedure requires inspec-tion of the liner plate adjacent to the attachments to verify the absence of injurious defects.
It also provides reference to Specifi-cation C-50 for rework criteria and includes criteria for initiating a nonconformance report.
The inspector discussed the above requirements with the gC engineer responsible for inspection of the liner plate attachment welding.
The FACE was familiar with the revised field procedure and stated that responsible field personnel were notifying gC in accordance with the field procedure.
The inspector had no further questions on this matter at this time.
(Closed)
Unresolved Item (387/79-19-02):
Radiograph Records One view of the radiograph for weld DBA-108-1-FM8 had been rejected.
The reshoot of view 10-11 had not been properly requested and view 11-0 had been mistakenly reshot.
Nonconformance Report No.
3888 was issued to document the acceptance of the weld without complete radiographic coverage.
The inspector reviewed the radiograph for view 10-11 of DBA-108-1-FM8 and identi-fied no further discrepancie The inspector reviewed the radiograph records for the five additional Class 1 welds with reshot radiographs.
No additional unradiographed areas were identified. Additional radiographs examined included:
DLA-102-1-FM 14 OLA-102-1-FM 3 DCA-108-1"FM 9 OCA-107-1-FM 2 DCA-103-1-FM 7.
The inspector discussed the above finding with the appropriate Bechtel equality Control Engineer and the authorized nuclear inspec-tor.
The inspector had further questions on this matter at this time.

Accident Involvin Unit 1 Core S ra Pum Motor 1P-206A On July 30, 1979 at approximately 3:30 p.m.
Core Spray Pump Motor 1P206A fell approximately 40 feet onto a concrete floor in a Unit 1 truck bay.
The motor fell as the result of the failure of the 7/8 inch diameter sling used for'lifting the motor.
An Equipment Installation Plan had been prepared, in accordance with Field Procedure FP-M-2, Revision 1, for the installation of four core spray pump motor A description of the accident and probable causes for the sling failure are discussed in the Bechtel accident report transmitted to PAL by Bechtel letter BCLPC-6567 dated August 21, 1979.
NCR-4269 documents the disposition of the damaged motor.
The inspector will review the imple-mentation of Field Procedure FP-M-2 regarding the handling of safety-related equipment during a future inspection.
No items of noncompliance were identified.

ACR/PGCC Rework a.
HYPOT Testin of General Electric Cables GE Field Disposition Instruction (FDI) MJGO Revision 3 requires the completion of AC HYPOT testing of all conductors in each GE cable inspected in accordance with the FDI.
Field Deviation Disposition Request (FDDR) No.
KR1-548, Revision 10, modified the HYPOT testing to require the performance of a DC HYPOT test and if necessary the AC test.
The stated reason for the change was that "many of the cables fail the AC test but pass the DC test.
This is because of capacitive reactance in the cables."
The inspector requested that the licensee provide a justification for the use of DC HYPOT testing where operating circuits are AC.
This item is unresolved pending evaluation by the licensee and review by the NRC (387/79-26-01).
b.
Deficienc in Am henol Connectors and Cutler Hammer E-30 Switches Bechtel MCAR 1-37 identifies two deficiences identified by site gC personnel during routine surveillance of work on ACR/PGCC panels.
The first deficiency concerns the failure of female pins to seat properly in amphenol connectors.
The relative position of the pins varies after mating and unmating of the connectors.
This is parti-cularly noted if the female pins have been removed and reinserted into the connector dielectric.
C.
The second deficiency concerns cutler hammer push-button switches installed in ACR benchboards.
Ten of 189 switches do not retract when manual depression is removed.
Resolution of MCAR 1-37 will be reviewed during a subsequent NRC inspection.
No items of noncompliance were identified.
Cable Ins ection On August 23, 1979, the inspector attended a meeting with representa-tives of PP8L, Bechtel, General Electric and the NRC regarding the application of a sampling plan to the inspection of electrical con-ductors in GE supplied cables.
The.sampling plan is described in FDI MJGO, Revision ll.
Unresolved Items Unresolved items are matters about which more information is required to ascertain whether they are acceptable items, items of n'oncompliance, or deviation.
An unresolved item disclosed during the inspection is discussed in par agraph 10. a.
