Construction Status The licensee reported that site construction work is 68% complete as of August 2, 1979. The licensee's project management personnel estimated that the construction of Units 2 and 3 was 79% and 55%
complete respectivel The licensee has issued a new construction schedule as follows:
SONGS 2 SONGS 3 Fuel Load 11/80 11/81 Initial Criticality 1/81 1/82 Initial Full Power 7/81 7/82 Full Firm Operation 10/81 1/83
-2 3. Licensee Action on Previous Inspection Findings The inspector examined the action taken by the licensee on the following outstanding items:
a. (Closed) Followup item (50-361/79-03/01): The records for the tanks built for Unit 2 by Brown Minneapolis Tank Company (BMT)
were not available for review during the inspection conducted January 23-26, 197 The records for the two refueling water tanks and the condensate storage tank for Unit 2 were reviewed. The inspector verified that the reQuired records had been submitted to SCE in accordance with the Vendor Quality Document List. Selected records were examined for completenes No items of noncompliance were foun b. (Closed) Followup item (50-361/78-17/01): The adequacy of plant procedures to provide for protection of items stored in place was addressed in IE Inspection Report No. 50-361/78-1 Portions of this item were resolved as reported in Report N /78-17/01. However, a complete review of the plant procedures had not been mad The inspector reviewed the plant procedure as reported in Report No. 50-361/79-01 and the results of the review were discussed with the licensee on February 15, 1979. All the procedures appeared to satisfy the storage and maintenance requirements of ANSI N45.2.2-1972, except that there were no provisions for documented periodic inspections of storage conditions for items stored in Zone V housekeeping area Subsequent to February 15, 1979, the licensee revised the plant procedure WPP/QCI 009 to include periodic documented inspections of all safety-related material in Zone V house keeping area This satisfies the requirements of ANSI N45.2.2-197 (Closed) Followup item (50-361/79-05/02):
SCE could not provide the acceptance standards for inspection of the welds on the diesel engines for the Unit 2 diesel/generator se SCE and Bechtel representatives reviewed with General Motors,%
the diesel engine subvendor, the welds identified by the NRC as having undercut and porosity. General Motors provided SCE with the acceptance standards and the welds were found to be within the acceptance standards for non-structural weld. Undersized Safety-Related HVAC Damper Actuators, 50.55(e) Report The licensee reported that approximately 15 damper actuators for Units 2 and 3 were undersized and would have to be modified or replaced in insure that the HVAC system would automatically align
-3 for the post accident condition. The damper actuators were not properly sized due to inadequate communication of engineering design information/criteria by University Mechanical and Engineering Contractors, Inc. (UMEC) among sub-tier suppliers, Air Balance (damper manufacturer) and Johnson Controls, Inc. (supplier of damper actuators).
The licensee initiated action to obtain the properly sized actuators for the HVAC dampers. The investigation conducted by the constructor, Bechtel, determined that the interface procedures between UMEC, Air Balance and Johnson Controls were adequate, but in this one instance had not been properly implemented. No other instances of improper implementation was reported. As no generic deficiencies were identified, the corrective action taken appeared to be satisfactor. 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 complete. In-.
stallation of Unit 3 internals is in progres No items of noncompliance or deviations were identifie. Reactor Coolant Pressure Boundary and Safety-Related Piping The piping related activities listed below were observed to ascertain compliance with applicable construction specifications and procedure Activity System Identification N Storage Safety Injection 3-SI-044-1 Grinding Feedwater 3-FW-190-4, Weld BC Pipe Welding Chilled Water 52-1513-ML-348, Sh. 2, Rev. 2, Weld SBA Grinding Cont. Spray 52-1206-ML-002 Sh.2, Rev. 8 Weld M (C)
Grinding Component Cool Water 3-cc-277-4 Cutting/Grinding Safety Injection 52-SI-045-1 The inspector observed a craftsman cutting a section of stainless steel pipe (spool 52-SI-045-1) with a grinding disc that was no identified as a disc to be used only on stainless stee This is contrary to the requirements of the construction procedure WPP/QCI 206, Revision 4, which states, "Grinding wheels, discs and wire wheels to be used on stainless steel or nickel base alloys shall be color coded by the tool room attendant or by the warehouse personnel with a white metal marke.
."
This is an item of noncompliance (50-361/79-20/01)
- The craftsman was questioned as to why the disc was not properly marked. He responded that the disc had just been obtained from the tool room and had not been properly marked. He immediately returned the disc to the tool room for markin No other items of noncompliance or deviations were identifie. Fire Prevention The applicable codes and standards for fire prevention were discussed with the San Onofre Units 2 and 3 Fire Marshal The Fire Marshall and the inspector toured Unit 3 containment building to observe the position of hose reels and fire extinguishers. Also observed was the storage of forms, lumber and scaffolding materials; the storage of flammable liquids; and the cutting and welding processes in pro gress. One hose reel was found partially blocked and one temporary fire hydrant was not protected by barriers. These items did not meet the requirements of Na'tional Fire Protection Association (NFPA) Standards Nos. 14 and 24 respectively. However, the in spector could not identify any commitment to fire protection codes and standards applicable to San Onofre Units 2 and 3 for constructio Subsequent to the inspection, the licensee's management personnel committed to define the fire prevention standards being implemented at San Onofre Units 2 and 3 for constructio. 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 equipmen No items of noncompliance or deviations were identifie.
Management Interview The inspector met with the licensee representati.ves.(denoted in Paragraph 1) on July 6 and 20, 1979. The scope of the inspections and the inspector's findings as noted in this report were discusse The licensee representatives had no additional comments.
