(Open) Noncompliance (31.1/78-26-01): Implementation of pipe welding design requirement The inspector examined records and interviewed responsible engineering personnel at the site on October 12, 1978 to ascertain. generic corrective actions in-progress relative to the socket welding noncompliance identified in IE Inspection Report 50-311/78-2 The inspector selected "typical end prep-sleeves 9, 10, 11 and 16 11 on drawing 218268-A~8903-12 as an item similar to Detail 17 on that drawin He examined the applicable weld history record for the 8
butt-weld on the containment exterior end of penetration #10, (Mark
- 2-RH-158, field weld #FW-2-RH-158-1), and associated vendor documents for fabrication of the pipe and its weld-end-preparation The inspector examined the following specific records:
Design Drawing 218268-A-8903-12 Isometric Drawing RH-2-3 Sheet 1 Detail Drawing 240295-D-4388-3 Sheet 25 Fabrication Drawings F-5791 (QC 10,002) Revision 1 F-6302 (QC 12,461) Revision 5 Weld Procedure EB 90.1 NU Weld End Preparation Detail (Kellog) SK-67 Revision 1 Weld History Record FW-2RH~158-l The design detail examined by the inspector appeared to have been translated into fabricatio~ control document The licensee repre-sentatives stated that it was their intent to select a sample of design details which have similarities to Detail 17, and audit the implementation of those details to assure proper implementatio The inspector stated that the results of that audit will be reviewed in conjunction with any other corrective actions described in the pending response to the previous item of noncomplianc The inspection reviewed the preliminary hydrostatic test program to be employed during the post-repair acceptance testing of the noncomplying socket weld He discussed the need for meeting construction code test pressures arid temperature criteria where applicable, and a safety evaluation of those systems where such testing is not feasibl (Open) Unresolved item (311/78-02-04): Nondestructive testing of the steam generator nozzle ring Further review of the foregoing item by the NRC established that the steam generator nozzle ring welds do require a liq~id penetrant test (PT) in accordanc~ with paragraph N-51 Concurrent with the review, the licensee performed a PT of the ring welds which disclosed 5 relevant indications (3 linear and 2 rounded).
Two of the linear indications have been removed by grindin The third linear and 2 rounded indications require additional wor It is anticipated that the final disposition of these indications will be performed after the hot functional testin *
- Licensee Followu Activities Relative to Items Re orted to NRC Under 10 CFR 50.55 e Automatic Transfer of 4KV Outside Feed The inspector examined documents relative to the licensee actions described in the June 2, 1976 PSE&G letter to NRC, as related to Unit (Similar and associated actions relative to Unit 1 were previously reviewed and are documented in IE Inspection Reports Nos. 50-272/76-24, 76-32 and 76-36.)
The inspector examined the Unit 2 Startup Procedure #SUP-29 dated June 22, 1977 Section 10.6; this provides testing to 11verify the control circuitry which pre-vents interruption of Safeguards Emergency Contra 1 s load sequencing during a blackout situation due to restoration of off-site power."
The inspector also interviewed responsible licensee personnel who stated that the control cabinets for both Unit l and Unit 2 were modified by the vendor at the same time, with changes described in the PSE&G June 2, 1976 letter. Based upon successful Unit 1 tests described in IE Inspection Report No. 50-272/76-36, and provision for similar startup testing for Unit 2, the inspector had no further questions regarding this matte Lube Oil and Jacket Heat Exchangers The inspector examined records of actions described in the licensee 1s May 5, 1975 letter to NRC regarding a slight leak through the heat exchanger cast aluminum/bronze head The records showed that the design working pressure of the heat exchangers is 150 psig, and the leakage occurred during the hydrostatic 300 psig test. Leakage rate was one drop in four hour Technical evaluations of the condition were performed by the diesel generator vendor (Alco), the licensee, and the architect-engineer*
(UE&C).
Joint audit (by Alco and PSE&G) were conducted at the shops of the heat exchanger manufacturer (BASCO Division - American Precision Industries).
On November 14, 1977, field pressure testing was performed, results evaluated, the condition reaffirmed for cooler No. 2C-EDG, and the condition determined to be acceptabl The inspector examined the following records relative to the above:

Containment Penetrations - Personnel Access Hatch - Records The inspector examined records relative to leak testing of the contain-ment personnel access hatch (airlock). The inspector evaluated the above items with regard to criteria delineated in the Salem Final Safety Analysis Report (FSAR) Sections 5.5 and 5.2.3 and Appendix D, including Codes and Standards commitments identified in the FSAR Section 5.2.8.2 and licensee/contractor specifications/procedures/
instructions numbered 68-7123 (w/Addendum 1 through 9).
The inspector considered the following aspects relative to the above:
test pressures and duration commensurate with containment design pressure and applicable ASME Code; review of test procedure by appropriate organizations and personnel; record of test result evaluation/
acceptance; records of repair and retest as requ1red; and retrievability of record The inspector examined the following quality-related records relative to the above evaluations:
Procedure (CB&I), AL (A through D), Revision l Record Drawing, SAB-lOlA Sheets l and 2 No items of noncompliance were identifie.
Primary Coolant System Accumulators - Records The inspector examined records relative to the primary coolant system accumulators designated as #21 through #24 (PNJ-SIATAT - #1 through #4).
The inspector evaluated these items with regard to criteria delineated in the Salem Final Safety Analysis Report (FSAR) Section 6 (Table 6.2.2)
and Appendix D, including Codes and Standards commitments identified in the FSAR Sectiori 6,* and licensee/contractor Purchase Order No. S46-F70616 *
The inspector considered the following aspects relative to the above:

Westinghouse Purchase Order #546-F70616 w/Change Notice dated March 6, 1969
PSE&G Data Review - Receiving Report #MR-231-546 and #MR-231-545 UE&C QC Inspection Report (Shop) dated February 17, 1970 Qua 1 i ty Contra 1 Drawing Conformance Check Report dated May 18, 1970 Westinghouse Specifications #676441, #676452, #677019 Delta Southern Co. Drawings #41050, #41045, #41051 Westinghouse QC Release #1342 ASME Form U-lA for drawing #41051-70-1 Westinghouse letter #PSE-78-516 dated May 4, 1978 Findings: The inspector identified two items as unresolved, as discussed in sub-paragraphs a and b belo The purchase order #F70616 references specifications #676441 and
- 676452; however, the specification #676452 is applicable to another reactor facility. Specification #677019 is the commen-surate specification for the Salem facility, but it is not referenced in UE&C microfilm records, files, documents examined by the inspecto However, a copy was located at the UE&C records center on sit Sizing, painting, and lifting-lug requirements of specification
- 677019 did appear in a March 3, 1969 Change Notice to the pur-chanse order, although the reference to specification #676452 had not been change Receiving and inspection records indicated that the appropriate parameters of specification #677019 had been trans-mitted to the vendor, inspected and confirme The licensee stated that a purchase order change notice existed which clarified the applicable requirements, but that this was not at the site, nor required to be at the site. This item is unresolved pending review of the clarifying documen (311/78-39-01) The purchase specifications #676452 and #677019 identify accumu-lator operating conditions as 120° to 150oF, and design temperature as 300° The Salem FSAR Table 6.2.2 identifies operating tempera-tures of 50° to 150° The specifications do not require verifi-cation of fracture toughness of the accumulator materials; this is consistent with the applicable ASME Code (1966 Section III Class C) and the FSA However, Westinghouse letter #PSE-78-516 (regarding Unit l accumulators purchased under the same purcha~e order) indicates that current code rules and material manufacturer *
practices suggest that the accumulator minimum operating tempera-ture be limited to 70° by procedure The Salem Precautions, Limitations and Setpoints Document provided by Westinghouse reiterates the 70° requiremen The operating procedure #OI-I.3.4 (Revision 3) incorporates the requiremen The records examined by the inspector support the conclusion that the operation of the accumulators will be consistent with their functional capability. However, it 1s not clear that the 50°F lower limit allowed by FSAR Table 6.2.2 may be permitted for the procured accumulators. This item is unresolved pending licensee review of the basis for the SAR 50°Fspecificatio (311/78-39-02)
Steam Generator and Pressurizer Level Transmitters The inspector examined records and inspected the physical installation of differential pressure transmitters of the liquid level sensing systems for four steam generators and the pressurizer (three trans-mitters for each equipment piece). Barton model #764 (serial #173 through 175) transmitters had been installed in the Pressurizer Pro-tection Channel cabinets to replace three model #386 original device Replacement of the 12 transmitters for the steam generators 1s also planne The inspector interviewed licensee and NSSS contractor site personnel regarding environmental qualification test result questions associated with this particular model transmitter at another site. The licensee representative ad~ised the inspector by telephone on October 19, 1978 that this matter was under review by the PSE&G off-site engineering group, that an engineering change notice was imminent, and that the matter is currently under review by NRR in conjunction with the main steam line break analysis for Salem Unit 2, and general NRR requests to PSE&G for equipme~t environmental qualification dat The inspector examined the following documents relative to the above:
