FSAR Depiction of Preferred Powe An FSAR change has been submitted for the physical arrangement drawing of the SONGS 2/3 preferred power supply to show the as built condition of power line crossovers. This item is considered close e. (Closed) Unresolved Item (50-362/80-06/01)
Equipment Storag The temporary shelters containing battery cells, emergency generators, and emergency diesel engines have been modified and now meet the intent of the storage conditions specified in ANSI N45.2.2 for those item The licensee has also started an increased surveillance program in the storage area to ensure the intent of ANSI N45.2.2 is met for all equipment. Since the applicable Bechtel procedure WPP/QCI-008
"Material Receiving, Pre-Installation, Storage, and Handling" is based on ANSI N45.2.2, a procedure change is not considered necessar Based on the licensee's commitment to increase surveillance of this area to ensure storage requirements of ANSI N.45.2.2 are being met, this item is considered close f. (Closed) Followup Item (50-361/79-29)
Allegation Concerning Weld Crack Repair of weld B on line S3-1201-ML-010 is complete. The inspector reviewed the weld repair documentation and viewed the final radiographs of the repair. The radiographs indicate an acceptable weld per ASME Section III, Subsection NB. Also, SCE Field Surveillance Reports W-1-80 and M-21-80 covering this weld repair were reviewed. This item is considered close g. (Closed) Noncompliance (50-362/79-27/01 and 50-361/80-06/02)
Weld Filler Metal Contro IE Inspection Report 50-361/79-29 Appendix A paragraph c and Inspection Report 50-361/80-06 Appendix A are citations dealing with welding electrodes not returned to the rod room attendent at the end of the shift. The licensees response dated May 28, 1980 committed to certain corrective actions; the principal actions being to revise WPP/QCI-200 Appendix VIII to require standard quantities of welding filler material to be issued, and documented daily checks of each craftsman to account for all filler material issued to the craftsma The inspector performed an audit of the Unit 3 work areas where welding had been in progress before the work stoppag No uncontrolled filler metal was observed. The inspector examined records of the field check of craftsman by the foreman for the weeks of 6/22 and 6/29/80 and observed the notation which indicated a check for weld filler material had been made. This item is closed based.on the
-4 actions committed in the licensee's response of May 28, 1980 and the fact that additional inspections will be made in the normal course of future inspection h. (Ooen) Unresolved Item (50-361/79-06/01)
Controlled Drawings Used in the Field Were Not the Latest Revisio The inspector determined throuqh discussion with the Drawing Control personnel that the white drawing stations are updated daily by document control personne The field personnel are responsible to insure the pink drawings in use in the field are up to date. Since no work was underway in the field, proper revisions of field drawings were not checke The inspector randomly sampled 6 drawings at Unit 3 station 15 and verified the revisions were up to date compared to the computer listing of July 14, 198 The inspector further determined through discussion with drawing control personnel that in addition to daily updates of all white drawings stations, a single white drawing station is audited each month. The inspector examined the audit results for the last several months and observed that the audit findings indicated that many drawings were found missing or out of date. The audit results were stated in general terms in most cases but indicated that the while stations were generally found to have a number of drawing error This item will be inspected further in a future inspection to determine if the pink drawings in use in the field are up-to-date when compared to the computer listin In the review of monthly audits the inspector observed that the monthly audit scheduled to be performed in February was dated February 1, 1980 whereas it had been actually conducted in April and May 198 The participating document control auditors signed the audit without dating their signatures. This was explained to be a method of keeping track of which audit was being conducted. Licensee personnel had the audit for the month of February corrected and committed to have a training session with the document control auditors. The inspector had no further questions regarding the dating of drawing station audit i. (Closed Noncompliance (50-361/79-23/01) and Followup Item (50-361/79-19/02)
Cable Tray Cleanliness
-5 Inspection Report 50-361/79-23, Appendix A is a citation regarding cable tray cleanliness. The licensee's response of November 27, 1979 committed to actions to avoid further violation The inspector examined the cable tray cleanliness in the Unit Control Building area 60 foot elevation, 50 foot elevation, and Switchgear Room 50 foot elevation. The general condition of cleanliness was found to be satisfactory. This item is considered closed based on the general condition of cleanliness observed and the actions committed in the licensee's response of November 27, 197 j. (Closed) Open Item (50-361/80-05/01)
Pipe Support Concrete Expansion Anchor Bolts Have the Ends Ground Of The licensee provided documentation that the pipe supports identified by the inspector in Report 50-361/80-05 were not safety related and therefore not an NRC concer The inspector examined Quality Class I pipe supports for evidence of length marking on the ends of the anchor bolts and sufficient embedment. The following supports were inspected and bolt length markings checked: SA SS 079 H OOC; S2 SS 166 H OCC; S3 SS 098 H OCK; SA GR 019 H OOA; SA AS 084 H 009; SA GR 003 H OAG; SA GR 007 H OAG; SA GR 099 H O One support SA GR 020-H OOA had questionable marking on two bolts in that the marking was very faint. The QC inspector who verified the anchor bolt installation was interviewed and stated at the time of verification (11-15-79) the markings were sufficiently clear for his verification. The inspector had no further question This item is considered close k. (Closed) Unresolved Item (50-362/79-09/02)
Liquid penetrant examination indications in pipe weld was determined to be non-relevant by visual examinatio During a previous NRC inspection, questions were raised concerning the disposition of liquid penetrant examination indications believed
-6 to be nonrelevant blemishes from grinding by means of visual examinatio The NRC's concern was that this practice could result in lowering the quality standards if abused by the testing personne Furthermore, this matter is addressed in paragraph NB-5351 of Section III of the ASME Boiler & Pressure Vessel Code. The inspector obtained a NRC regulatory position on this issue which was discussed with the licensee and is as follows:
"Prior to making a final determination that indications assumed to be caused by surface conditions are non-relevant, sufficient surface preparation and reexamination should be performed to establish the character of the pipe. Enough random sampling should be done to convince the inspectors involved that the indications are due to the surface roughness and imperfections such as scratches and blemishe Once the character of the pipe is established the inspectors may agree that the surface condition can remain "as is" provided the non-relevant indications are not sufficiently dense in any area to mask indications of defects."
During these discussions with licensee and A/E personnel, the inspector determined that the licensee's nondestructive examination (NDE)
QA engineer conducts audits for NDE and specifically checks for adequacy of interpretation of indication Further, the examinations have a degree of redundancy in that the liquid penetrant examinations are repeated by a different crew of examiners for preservice examination Additionally, the authorized inspector is accompanied by a Bechtel escort who is a qualified Level II examine At the exit interview, licensee management committed to continue audits and surveillances to ensure liquid penetrant examinations are conducted in accordance with the requirements of the ASME B&PV Code and the NRC's position concerning indications considered to be nonrelevan This item is closed based on the licensee's commitment and the fact that NDE will be examined further in the normal course of future NRC inspection. Pipe Support Concrete Expansion Anchor Bolt Installation The inspector examined Specification CS-C8, Design, Installation and Testing of Concrete Expansion Anchors Rev. 7, of May 12, 1980 as amended by SCN's CS-244, CS 243 and CS 240 and Procedure WPP/QCI 011 Installation of Concrete Expansion Anchors Re of 1/7/80 as amended by PCN 4 of 2/27/80 for compliance to IE Bulletin 79-02 Rev. 2 Pipe Support Base Plate Design Using Concrete Expansion Anchor Bolt The examination revealed several areas where bulletin requirements were not covered by the procedures.reviewed. The inspector provided comments on the procedures to cognizant licensee personne Licensee management at the exit interview committed to review and resolve the comments. This item will be inspected further on a future inspection (50-361/80-10/01).
5. Qualification of Non Destructive Examination Personnel The inspector examined the qualification and certification of Nondestructive examination personnel for compliance to the requirements of Peabody Testing Inc., Quality Assurance Plan, Project QA Administration 2.3, Qualification and Certification of Non Destructive Examination Personnel, San Onofre Nuclear Generating Station Units 2 & 3 and SNT-TC-1A 1975 Editio The inspector determined that Peabody's administrative requirements for qualification and certification of personnel meet the requirements of SNT-TC-1A. One aspect of the qualification requirements is more relaxed than recommended by SNT-TC-1A,. that is, the Peabody requirements allow the
"Specific" portion of the written examination to be an open book examination whereas SNT-TC-1A recommends the examinations be administered closed boo Since SNT-TC-1A presents itself as guidelines and allows for modification of its recommendations and since the nature of the material provided for the open book test is codes and standards, the inspector had no further question The inspector examined the qualification records of five Level I and II NDE personne No items of noncompliance or deviations were observe.
Code Plate Welding Allegation An allegation was received by the resident inspector regarding nonconformance report P-1853 concerning tack welding of a code plate (weld SCE) on pipe S2-1305-ML-099 Sht. 3. The NCR (date May 6, 1980 and subsequently invalidated) indicates that the welder assigned to weld the code plate (based on his welding symbol being on the filler metal withdrawal form)
did not in fact weld the code plate to the pip The NCR was written based on a note written by the welder to a welding QC inspector indicating that he had not performed the weld even though the weld papers indicated he was the welder. The welder subsequently signed a statement that he did in fact make the code plate tack welds. The NCR was then invalidated and the alleger contacted the NRC resident inspector with a concern that the welder had been pressured into changing his story. During the inves tigation, the code plate tack welds were visually examined and appeared satisfactory. In addition, the welder was interviewed and questioned about the change in story and possible pressure applied. He stated that no pressure had been applied to him by anyone and that when he wrote the original note that he did not think he had made the weld. After review of the the records and giving the matter further thought he then came to the conclusion that he did in fact tack weld the code plate to the pip Based on the visual examination of the code plate tack welds, review of the welding records, and interview with the welder, the inspector considers this item close.
Followup on 10 CFR Part 21 Deficiencies Licensee action regarding the following.Part 21 reports was reviewed:
a. Exide Battery Racks Based on a Part 21 report from Exide, additional isolation bars are required to be added to the Class IE battery racks to isolate, in two-cell increments, the build up of horizontal momentum in a string of cells on a rack during a seismic event. The battery racks for both Unit 2 and 3 batteries were inspected to determine status of the modification. There are 48 required isolation bars for each Unit. All but six isolation bars have been installed in Units 2 and 3. The project is awaiting delivery of parts to complete the Unit 3 installation. The six isolation bars not yet installed are for battery rack 3B010 and is documented on NCR E-56 The inspector considers this item closed for the purpose of NRC followup based on the item being tracked on Bechtel's nonconformance report syste b. Exide Batteries A Part 21 report from Exide concerns failure of the Class IE batteries to meet the discharge test of IEEE Standard 450 for the 20 year life of the batteries as specified in the purchase order. Exide is unable to deliver redesigned batteries at this time and the original batteries are installed in Units 2 and 3. The licensee plans to replace the batteries at the first refueling outage and is tracking this item on their outstanding items tracking syste This item is considered closed for the purpose of NRC followup based on the item being tracked on SCE's syste. Management Interview The inspectors met with licensee representative (denoted in Paragraph 1)
on June 20 and July 18, 1980. The scope of the inspection and of the inspectors' findings as noted in this report were discussed.
