Follow-up of Previously Identified Items a.
Noncompliance - Steam Generator Chemistry (82-30-01, Closed)
A review of the actions taken by the applicant confirmed that the
. clearance procedure has been ' revised and more restrictive controls have been required of those individuals having clearance authorities.
In addition, the inspector noted that shifts were directed to hold training sessions on the design features of,the feedwater isolation and control valves.
b.
50.55(e) Report 82-40 - Prerequisite Test Review (Closed)
-Based on a review of the actions taken by the applicant, the inspector confirmed that a prerequisite test review group has been formed with responsibility to review all completed prerequisite test data packages. A procedure has been developed defining their review responsibilities and this group has been functioning since the resumption of electrical testing.
No items of noncompliance or deviations were identified.
3.
Maintenance The following maintenance records and activities were reviewed during the perio.
Unit 2 fuel pool cooling pump PM (records)
a.
b.
Unit 2 instrument compressor PM (records)
c.
Unit 1 diesel generator lube oil pressure safety valve testing (observation)
The inspector confirmed that the preventative maintenance tasks frequencies and check sheets have been defined for items (1) and (2) and that records indicated the work has been completed consistent with assigned frequencies.
The inspector noted that the PM program has not yet been fully developed to support an operating plant. Considerable procedural development work remains to be completed. This was brought to the attention of APS management.
While observing preparation for testing the B diesel generator lube oil pump pressure relief valve, the inspector noted that the instructions had not included the valve relief setting. This observation had also been made previously by the QC inspector who was in attendance at the work site. The work had been stopped because of this. With the above exception, the work control package contained reviews, approvals, inst ructions (which APS QC also challenged), technical references, QC hold points, and data sheets.
No items of noncompliance or deviations were identified.
4.
Startup-Testing a.
Discipline Test Schedule The prerequisite test program descipline test schedule is in its final phases of review. This review is intended to establish the accuracy of the testing requirements and status of test completion as well as confirm that test data packages are on file for those tests that have been completed. Approximately 20,000 prerequisite tests are involved.
One of the findings to date is that 19 safety-related prerequisite electrical tests which the schedule showed as complete had been previously rejected or not completed. The inspector was informed that these tests will be done.
b.
Test Observations Portions of the following preoperational tests were observed:
(1) Containment Spray System (2) Auxiliary Feedwater System
.
.
The inspectors observed that approved procedures were being used and that the testing, data acquisition, and recording were in accordance with procedures.
No items of noncompliance or deviations were identified.
5.
Reactor Coolant (RC) Pump 2A The inspector was informed by APS of a problem with reactor coolant pump 2A.
While attempting to drain oil from the pump bearing lubrication system into an oil reservoir, asia check for-proper oil volume, oil'
overflowed the drain system due to the drain line being plugged by a rag.
Tae overflowing oil ran down the pump shaft.
Inspection of the pump seals revealed the presence of oil. The motor and pump seal package were pulled and the reactor coolant piping at the pump _ location was checked.
No oil was observed to have leaked into the RC piping. Oil was also believed to have drained into the reactor drain tank through the third stage seal leak off-line. The seal leak off line and the reactor-drain tank were flushed and chemically cleaned. The plugged drain line would not have interfered'with the operation of the pump as it was not in the oil circulation portion of the system.
No items of noncompliance or deviations were identified.
6.
Plant Tours Several tours were made during the period with Bechtel and APS representatives participating in the walk downs. The building housekeeping was very good, and showed evidence of considerable effort and attention by Bechtel and APS cleanup crews.
No instances of equipment damage or abuse were observed. Fire protection equipment was in place and equipment protected from welding operations.
Several emergency light packages were tested and found to be inoperable.
APS has not made its final check of these units as yet and will repair or replace inoperable equipment at a later date. A review of the shift test coordinators log confirmed that problems requiring follow-up are being highlighted. Water chemistry analyses are being performed and test results indicate specifications are being maintained.
No items of noncompliance or deviations were identified.
7.
Startup Quality Assurance / Quality Control (QA/QC)
The inspector reviewed several corrective action reports (CARS) issued by QA/QC. A check by the inspector of one dealing with instrument and control circuits wiring verification test changes confirmed that it is receiving APS management attention.
Another dealing with the possible required retesting due to potential invalidation of testing as a result of design changes is also being evaluated by the startup testing organizatio.
.
.
A review of outstanding corrective action reports revealed that approximately 65 are still open and require action by responsible organizations. Responses are overdue on approximately 35 CARS. APS management is aware of this situation.
No items of noncompliance or deviations were identified.
8.
Fuel Receipt A total of 246 fuel assemblies (includes five spares) have been received onsite. All bundles have been inspected and are stored in a checker board pattern in the spent fuel pool except five which are stored in the new fuel storage pit. The inspector observed fuel unloading, inspection and transfer operations during the period and found them to be in accordance with procedures. Several checks of the crane interlocks were observed and found to operate properly. The fuel building is kept locked and entry requires permission from the shift supervisor. Housekeeping in the area was found to be very good.
No items of noncompliance or deviations were identified.
9.
IE Information Notice No. 83-08 - Component Failures Caused by Elevated DC Control Voltage The inspector discussed with applicant personnel the' safety implications and generic concerns of elevated voltage conditions in DC control systems. The proposed Technical Specifications at present will'not require that the station batteries undergo an equalizing charge.providing that they meet surveillance requirements. The running voltage of the DC systems will be 134 bolts on float / charge, well below the maximum rated voltage of 140 volts for system components.
The applicant's personnel are fully aware of the implications of extended operation at elevated voltage in DC systems and are endeavoring to maintain the voltages in these systems below the maximum rated voltage.
No items of noncompliance or deviations were identified.
10.
Test Procedure Review The applicant's preoperational test program for response time testing of instrumentation associated with the reactor protection system, supplementary protection system and ESFAS was examined by the inspector.
It was determined that the program meets the requirements of the applicable standards. The inspector discussed the test procedure with the cognizant engineer. The intent of the testing will include an actuation of the reactor trip breaker undervoltage coils with the shunt coils jumpered out.
This step in the procedure will effectively test the response of the undervoltage coil.
The inspector also discussed the testing of instrument loops to determine the scope of the testing. The procedure to be used in testing instrument loops will test each loop from the sensor or transducer all the way through to the output of the loop. The test will include the introduction of an actual input, such as a pressure of differential
