- +. Construction Status The licensee reported that site construction work is 64% complete as of January 24, 1979. The licensee's project management personnel estimate that the construction effort is split 60%/40% between Units 2 and. Licensee Action on Previous Inspection Findings The inspector examined the corrective action taken by the licensee on the following outstanding item a. (Closed) Followup Item (50-361/78-18/04): Handling of low hydrogen weld rod shipping container The licensee issued Corrective Action Request F-725. As a result of this CAR, the rod room attendants now examine all shipping containers as they are delivered to the rod room All containers which have ruptured seals are segregated for disposa The Resident Inspector has looked for damaged containers in the rod rooms for both Units 2 and 3 during the routine plant tours. No containers with ruptured seals have been foun b. (Open) Followup Item (50-361/78-18/02): Missing diesel generator vendor document The vendor documents for the Unit 2 North D/G were received by Bechtel, but many of the records were illegible. Records of better quality have been requeste. Cracking of Spent Fuel Pool Liner Plate, 50.55(e) Report The final report concerning a reportable condition relating to cracking of stainless steel liner plate used in the spent fuel handling and storage facilities was submitted to the NRC on August 31, 1977. This report described plans for the licensee to do additional crack monitoring and investigation of the liner plates used for the spent fuel handling and storage facilities and to conduct a general program to randomly test stainless steel sumps, tanks and pipes to verify the low potential for cracking in other stainless steel at San Onofre Units 2 and 3. The crack monitoring and investigation of the liner plate was reviewed by the NRC inspector. This program established the bounds of the cracks in the liner plates and verified that cracks did not continue to propagate beyond the original test indications and that other areas of high potential residual stress did not show indications of crack initiatio As a result of the experience gained in the evaluation of the liner plate cracks, the licensee concluded that other stainless steel components and systems in the plant did not have the potential for cracking due to the absence of excessive residual stresses and that the inspections and tests required as part of the present Quality Assurance Program was adequate. Accordingly, a separate general program to randomly test stainless steel sump, pipes and tanks was not conducted. The basis for this conclusion was reviewed by the NRC inspector and found to be satisfactor. Control Element Drive Mechanism (CEDM) Nozzle Cone Modification, 50.55(e) Report In a letter to the NRC dated August 30, 1978, SCE committed.to modify the CEDM nozzle cones in accordance with the corrective action in the 10 CFR 50.55(e) report from Arkansas Power and Light Company to the NRC Region IV, dated April 19, 197 The corrective action required the nozzle cones be tack welded to the nozzles in addition to the use of a set screw to prevent the nozzle cones from coming off the CEDM nozzles. The Resident In spector verified that the nozzle cones had been tack welded in accordance with the instruction. Use of Temporary Pipe Supports During Startup Testing The program for use of temporary pipe support during startup was presented to the Resident Inspector on January 5, 1979. The pro gram included plans to assure all temporary supports are adequate for the pre-operational testing program and that all required tests for the permanent supports are performed after the permanent supports are installed. The program presented appeared adequate to assure that components and systems important to safety would not be com promised by the use of temporary pipe supports during the pre operational testing progra. Electrical Equipment Storage and Installation a. Diesel Generator (1) Storage The storage of the diesel generator and components was observed to be in accordance with the Bechtel procedure WPP/QCI 008, Rev. 9, except for the motors for the Fin Fan Radiators. The vendor (Stewart and Stevenson Service)
manual required that the motor and fan shafts be rotated every seven days. Bechtel obtained relief from the vendor on this requirement to allow the shafts to be rotated every thirty days. However, this requirement was
not met and the inspector was advised that an noncon formance report would be initiated. Also, the inspector noted that the vendor manual was received on site on August 30, 1978 and the equipment did not arrive until December 1, 1978. The cause for the delay in issuing the supplemental maintenance requirements to rotate the radiator motor shafts every thirty days has not been determined.. This is an unresolved ite (50-361/79 05/01)
(2) Installation The installation of the Unit 2 North diesel generators was observed including aligning, leveling and anchor bolt installation. The installation was in accordance with the vendor requirement (3) Welding A general inspection of the diesel generator was con ducted. The inspector observed welds on the diesel engines that had porosity, undercut and rollover. Because the engines were purchased as an "off-the-shelf" item with commercial quality, the welding criteria for judging the acceptability of the welds was not available. SCE management personnel stated that action would be initi ated to determine the acceptability of the welds. This area will be reviewed in a future inspection when the acceptability of the welds can be determined. (50 361/79-05/02)
8. Reactor Vessel and Internals Storage The construction activi-ties were observed to ascertain compliance with the licensee's procedures for storage of Unit 2 and 3 reactor vessel and internals regarding access control and use of protective cover No items of noncompliance or deviations were identifie. Exide Battery IE Inspection Report 50-361/78-20 discussed the outstanding defi ciency on the battery racks for Units 2 and 3. The report stated that the seismic qualification report for.the racks was incomplete and that the racks had not been released for installation. The racks have been released and the Unit 2 racks installed as allowed by the licensee's QA program. The installation of Unit 3 battery racks has been initiated. There is an outstanding "Hold" tag on
each of the racks which will require a modification of each rack as identified in the vendor's Part 21 report to the NRC. Bechtel is to assure the required modifications are completed prior to release of the racks for servic. Preservice Inspection Observation of Work The 0 and 450 scans for the Unit 2 pressurizer support flange were observed. The work was performed in accordance with procedure NIP 743. The personnel qualification records for the Level II technicians were reviewed for compliance with ASNT-TC-l No items of noncompliance or deviations were identifie.
Plant Tour The inspector toured both Units 2 and 3 several times each week during this inspection report period. Particular attention was directed to observing work in progress and availability of super vision and quality control inspectors at the work areas, housekeeping and preservation of equipmen No items of noncompliance or deviations were identifie. Mlanagement Interview The inspector met with the licensee representatives (denoted in Paragraph 1) on January 5, 12, 19 and 26, 1979. The scope of the inspections and inspector's findings as noted in this report were discussed. The licensee representatives had no additional comments.
