5.
Independent Inspection The inspectors toured Warehouse B and inspected hydraulic snubber storage and protection and reviewed SCE&G/QA surveillance report No.
1-48, " Warehouse Storage - Type I."
The inspectors observed installation activities on valve 1-8811B in Safety Injection line I-SI-05-04 in the Auxiliary Building and in-stallation of pipe supports in the intermediate building. QC in-spectors were interviewed concerning inspection procedure...-

No items of noncompliance or deviations were identified.
6.
Safety Related Pipe Support and Restraint Systems The inspectors examined procedures, completed installations and quality records for safety related pipe supports.
a.
The inspectors examined the following procedures to determine whether they provide means for assuring the technical adequacy of safety related pipe supports and whether they comply with NRC and licensee requirements and licensee commitments.
(1) DCC QCP-VII-07, Rev. 5, " Inspection of Fabrication and Installation of Hangers and Support" (2) DCC WP-VII-07, Rev. 6, " Fabrication and Installation of Hangers and Supports" (3) DCC AP-III-02, Rev. 4, " Field and Engineering Changes" (4) GAI Specification SP 701-4461-00 (5) Detail drawings for the supports listed in paragraph 6.b below.
b.
Documents listed in paragraph 6.a above were used to verify proper conLiguration, location, installation, material certi-fication, bolting material, and weld condition for the following component support structures and snubbers:
Supports Snubbers CCH-386 CCH-756 CCH-246 CCH-335 CCH-227 RHH-228 CCH-1074 RHH-166
CSH-1002 SIH-086 RIG-099 RHH-lh0 While examining pipe support CCH-386, it was noted that one leg of the component structure of the support was located about one foot from that shown on the detail drawing. An FCR had not been initiated for this change in design location.
Paragraph 3.1 of DCC AP-III-02 states that "an FCR shall be used to document request to deviate from design documents." The QC inspector had signed item 3 of the Hanger Fabrication / Installation Checklist which states " verify fabrication / installation demensions as shown on hanger drawing."
This lack of required documentation and

improper verification appears to be in noncompliance with 10 CFR 50, Appendix B, Criterion V and has been identif ed as Infraction 395/79-01-01.
c.
The inspectors examined completed installation pickets for the snubbers identified in paragraph 6.b above for completeness and accuracy. For snubber installations RHH-099 and RHH-100, the snubber installation checklist had been signed by the QC in-spector on items Nos. 5 and 11 verifying the locking of PSA bolts and indicating the lockwiring of dust cover screws was not re-quired. The inspectors observed on January 11, 1979, that the fasteners on these snubbers were not locked.
No justification was provided for not lockwiring the dust cover screws. This improper verification appears to be in noncompliance with 10 CFR 50, Appendix B, Criterion V and has been identified as another example of Infraction 395/79-01-01.
7.
Safety Related Components II - Observation of Work and Work Activities The following procedures and drawings were examined and used to eval-uate storage, handling, installation, location, protection after installation and nonconforming activities for the Waste Gas Compressor (XGC-1A-WG), a safety related component outside the reactor coolant pressure boundary:
a.
Gilbert Drawing E-412-101 Rev. 14 b.
Gilbert Drawing IMS-09-012-3 c.
SCE&G FQCP 3.2.0, Rev. 12 d.
SCE&G FQCP 6.2.2, Rev. 6 SCE&G Deficiency Notice (DN) 535
.
No items of noncompliance or deviations were identified.
8.
Followup on Regional Requests Three ite arought out during hearing board testimony were examined.
,
a.
Required clearances between circulating water pump inlet and sur-rounding structures. The inspectors examined vendor and con-struction drawings and vendor correspondence approving the cir-culating water pump layout.
No discrepancies were identified.
It is also noted that these pumps are not safety related equipment.
b.
Material requirements for shims on safety related equipment.
Discussions with construction crafts and QC personnel indicated that stainless steel shims are used unless other materials are specified by manufacturers or design documents. A review of several construction /QC procedures showed that specific shim materials are not specified. Equipment shims are not considened safety related materia,
