Areas Inspected:
Routine, unannounced inspection by the resident inspector of construction activities including:
reactor pressure vessel and internals protection, 10CFR50.55(e) report followup, fire in fuel pool area, licensee corrective actions on previous inspection findings, and general work in progres The inspection involved 13 inspector-hours onsite by one NRC inspecto Results:
No items of noncompliance or deviations were identifie RV Form 219 (2)

DETAILS 1. Persons Contacted Southern California Edison Company (SCE)
- P. A. Croy, Site Quality Assurance/Quality Control Supervisor R. Frick, Quality Assurance Engineer R. R. Hart, Construction Superintendent D. E. Nunn, Manager, Quality Assurance J. H. Pantaleo, Quality Assurance Engineer
C. A. Blum, Quality Control Manager J. E. Geiger, Project Quality Assurance Supervisor
- L. W. Hurst, Project Field Quality Assurance Supervisor The inspector also contacted other licensee employees during the inspection. These included construction craftsmen, engineers and foreme *Denotes attendees at management meeting on January 28, 198. Construction Status The licensee reported the site construction work is 78% complete as of January 31, 1980. The licensee's project management personnel estimated that the construction of Units 2 and 3 was 89% and 66%
complete, respectivel. Licensee Action on Previous Inspection Findings The inspector examined the action taken by the licensee on the following outstanding item:
(Closed) Followup Item (50-361/79-24/01): Containers marked with the following trade names were found in the Unit 2 Containment:
ENVY, Instant Cleaner by Johnson SAFETY SOLVENT by Loctite RAPID TAP, Cutting fluid by Relton These items were not approved for use in the Unit 2 containmen However, a discussion with the technicians that had access to the containers disclosed that the materials had been used only to clean electronic components of automated inspection equipment. All the
-2 unauthorized material was immediately removed from the containmen Subsequent inspections of the containment areas by SCE and the NRC inspector verified that unauthorized chemicals were no longer being used. The inspector had no further questions on this ite. (Closed) Followup Item (50-361/79-30/01):
10CFR5O.55(e) Report on Incorrect Material for Retaining Clip of Thermal Pressure Relief Devices on WKM Gate Valve SCE issued a report to the NRC Regional Office dated December 12, 1979, describing the deficiency and the corrective action take A carbon steel retaining clip was substituted for a stainless.steel clip in the thermal pressure relief valves for the gate valves supplied. Corrosion of the carbon steel clip in process fluids such as borated water could cause it to release the poppet stem of the thermal pressure relief valves. This would allow the poppet stem, a cylinder approximately 1/10 inch in diameter and 1/2 inch long, to be carried through the flow path of the associated syste Resolution of this nonconformance was controlled under the provisions of the licensee's quality assurance program. The corrective action taken was to install a pipe plug of qualified material with a through hole small enough to retain the poppet stem, but provide a bleedoff to relieve any valve body pressure buildup i'n the downstream side of the bored hole provided for the pressure relief valve. The plug was staked in position after assembly to preclude it from backing out. This action was taken on all valves where a loose part the size of the poppet stem could have a detrimental effect on the associated system function or operation. All the valves to be used in the construction of San Onofre Units 2 and 3 have been modified as require This completes the followup of this reported deficienc. Fire in Unit 3 Fuel Pool On January 22, 1980, a small fire occurred at the south end of Unit 3 fuel storage poo Hot material from an overhead welding operation ignited the paper covering the stainless steel liner plate. The inspector observed the area where the paper had burne There was no evidence that the liner plate had been damaged. The inspector had no further questions on this matte *
-3 6. Reactor Vessel and Internals Installation and Storage Site activities for storage of the Units 2 and 3 reactor pressure vessels and internals were observed. Both vessels are installed and installation of Unit 2 internals is essentially complet Installation of Unit 3 internals is in progres No items of noncompliance or deviations were identifie. Plant Tour The inspector toured both Units 2 and 3 several times each week during the inspection,,report period. Particular attention was directed to observing work in progress, availability of supervision and quality control inspectors at the work areas, housekeeping and preservation of equipment. The inspector observed that a'section of W6x20 wide flange I-beam material was being held for quality control test. Followup with SCE QA personnel revealed that Bechtel had issued a nonconformance report (No. P1380) for linear indications near one end of the beam. The indications were visually identified by construction craftsmen. Subsequently, Bechtel and Peabody Testing nondestructive examination personnel confirmed the indications using the liquid penetrant test technique. The maximum depth of the indications were determined by grinding to be 0.056 inche This was within the ASTM A-6 material specification's acceptance limit However, the part of the beam with the indications was scrapped.
The action taken by Bechtel in accordance with the nonconformance report appeared to be appropriat No items of noncompliance or deviations were identifie. Management Interview The inspector met with the licensee representatives (denoted in Paragraph 1) on January 28, 1980. The scope of the inspections and of the inspector's findings were discussed. The licensee representa tives had no additional comments.
