requires that prior to plant startup the licensee _shall implement procedures to manually transfer diesel generators cooling water from the normal Safety Auxiliary Cooling System (SACS) loop to the alter-nate SACS loop in the event of a loss of a pump in the normal loop.
The inspector reviewed licensee procedure OP-AB.ZZ-124(Q) which covers this transfer.
No deficiencies were identified. This item is closed.
(Closed) Inspection Item 85-14-3F from SER Section 9.5.5, which
--
requires that prior to plant startup the licensee shall implement procedures which direct personnel to monitor diesel generators lube oil and cooling water expansion tanks for leakage of oil into the water and/or water into the lube oil.
The inspector reviewed licen-see Emergency Diesel Generators Operation Procedure OP-SO.KJ-001(Q)
which provides for monitoring these tank levels to detect leakage.
No deficiencies were identified.
This item is closed.

--
'
quires verification of licensee posting of diesel generators lube oil fill procedures. The inspector verified that each lube oil fill loca-tion is tagged with an etched micarta-type tag which provides direc-tion to Emergency Diesel Generator Operation Procedure OP-SO.KJ-001(Q)
for instructions and also provides a description of the type of oil '
to be used in the diesel engine.

4.0 Previous Inspection Findings
--
(Closed) Unresolved-Item 84-21-04 on safety-related flow switches FSL-9384 C1, C3, G1 and G3 installation not in accordance with the P&ID and calculations not available for review. The inspector re-viewed the licensee's corrected P&ID, flow calculations, and verified the actual flow switch installations. This item is closed.
(Closed) Significant Construction Deficiency Item 83-00-16 on GE
--
supplied ground break relays.
Eight GE model TGSR-12 ground break relays installed in safety-related 480 volt unit substation 108410, 108420, 108430, 108440, 108450, 10B460, 108470, and 108480 were supplied with a latent manufacturing defect in one of the component parts.
The inspector reviewed the corrective actions taken which was to return the relays to the manufacturer who supplied new model TGSR-12Z replacement relays.
The inspector reviewed the licensee quality control replacement documentation package and physically verified four of the replacement installed relays.
There were no outstanding questions.
This item is closed.
--
(Closed) Significant Construction Deficiency Item 83-00-13 on Defective AKR-30 Circuit Breakers.
The inspector reviewed the failures history of the General Electric AKR-30 circuit breakers at the Hope Creek Nuclear Station. Major failures included extensive problems with a defective switch and an improperly heat treated part which resulted in failures of the circuit breakers to close properly upon command.
The licensee and GE initially rebuilt substantial numbers of these circuit breakers in a General Electric warehousing location.
Because of continuing problems, all 244 AC and 91 DC AKR-30 circuit breakers were shipped to the GE Plainfield, Connecticut facility for remanu-facture. These circuit breakers were returned to the licensee and each circuit breaker was functionally tested prior to installation.
The inspector reviewed the repair / rework, and the licensee inspection test program for the remanufactured circuit breakers, and completed test and inspection data.
Since the circuit breakers are used in both safety and non-safety related applications, the inspector verified that all AKR-30 circuit breakers are treated as safety related such that there is inter-changeability of circuit breakers and parts.
_
.
.
Since re-installation, the licensee reports that there have been no significant failures in these circuit breakers. This item is closed.
--
(Closed) Significant Construction Deficiency Item 84-00-17 Brown Boveri model 5HK circuit breakers arc suppression puffer piston connecting rods.
The inspector reviewed licensee inspection documents and actions taken to resolve this deficiency. All 5HK circuit breakers puffer piston rods and arc chutes had been examined for evidence of damage. Arc chutes and covers were replaced where damaged. Two cracked / defective piston rods were replaced.
Licensee inspection procedure MD-PM.PB-001(Q) now requires the periodic inspection of the puffer piston rods.
There were no outstanding questions.
This item is closed.
--
(Closed) Unresolved Item 84-21-03 on de-energized electrical equip-ment heaters for diesel generator alternators, core spray pump motors, and residJal heat removal pump motors.
The inspector reviewed the licensee's findings, inspections made, corrective actions taken, and action / procedures implemented to prevent recurrence.
The licensee had identified equipment in the power block that is considered in level
"B" storage which no longer requires temporary heat and had also clearly specified 9 categories of motors, alternators and other electrical equipment which will continue to require temporary heat. This item is closed.
(Closed) Unresolved Open Item 84-21-02 on a safety related cable
--
bend exceeding the minimum acceptable bend radius.
The inspector verified licensee corrective actions taken, additional inspections conducted for evidence of other similar problems, and actions taken to preclude recurrence of the problem. This item is closed.
--
(Closed) Unresolved Open Item 84-21-01 on unsupported safety related cable span exceeding 18-inches.
The inspector reviewed the licensee response and inspected the refer-enced cable in place. The licensee response and inspection confirmed that the cable did not exceed licensee specification requirements for 18-inches horizontal and 48-inches vertical unsupported cable length.
The unsupported length was found to span 10-inches horizontal and 30-inches vertical. This item is closed.

(Closed) Unresolved Item No. 84-21-05 on sealing requirements for
--
unconnected instrumentation tubing and ports during installation.
The inspector reviewed licensee procedure SWP/P-15, Rev 10 which now requires that all open ports be properly sealed during installation.
This item is closed.
(Closed) Unresolved Item 84-21-06 on a missing explosion proof lamp
--
cover in ICD 411 battery room. The inspector found that at the time of the previous inspection the subject lamp was c.a improper fixture and was mechanically installed but not electrically connected. The proper lamp fixture has since been ordered and installed. The in-spector verified the installation and inspected the lamp-for instal-lation of the explosion proof covers. There were no outstanding questions. JThis item is closed.
(Closed) Unresolved Item 85-17-02 on licensee procedures to assure
--
control of battery room doors.
The inspector reviewed the recently implemented PSE&G/Bechtel Plant Access Authorization Permit / Request Procedure - SWP/P-136, H-SDP-141.
Personnel have been trained in the use of the procedure and access authorization authority has been assigned for five plant areas. The inspector verified that all battery room doors were closed and locked and that access could only be gained by proper authorization and key issue. This item is closed.
(Closed) Unresolved Item 85-17-03 on proper notifications when bat-
--
tery test data is outside the acceptance criteria established in test procedures.
Previous requirements were for verbal reports to the shift supervisor.
In such instances there was no clear verification of the reports having been made.
The inspector reviewed the current written reporting requirements of MD-ST.PR-001(Q) and SA-AP.ZZ-020(Q) and found them acceptable.
This item is closed.
--
(Closed) Unresolved Item 85-17-04 on not recording battery float voltage on test data sheets.
The inspector found that the subject battery was open circuited at the time and not on float. Therefore, there was no float voltage. The inspector also reviewed procedure MD-ST. PK-001(G), Revision 0, attachment 1 page 3 of 4 which now requires that all blanks on test data sheets be filled out as appli-cable or not applicable prior to QA sign off. This item is closed.
(Closed) Unresolved Item 85-17-05 on the ambiguity of battery sur-
--
veillance acceptance test criteria due to test procedural reference to draft technical specification criteria.
The inspector reviewed current battery test procedures which now include the acceptance criteria within the procedure for each test.
This item is closed.
