Pipe Support Baseplate Designs Using Concrete Expansion Anchor Bolts-Work Activities and Records (Units 1 and 2)
In response to IE Bulletin 79-02, tis licensee has initiated a surveil-lance, inspection and test program t a verify the adequacy of piping supports and restraints. An inspeccion of licensee records and work activities was conducted to verify compliance with licensee commitments and IE Bulletin 79-02 requirements. Surveillance records for the completed inspection of portions of the High Pressure Injection System in the Unit 1 Auxiliary Building and Containment Building were reviewed. Test records for package 11 of the Unit 1 High Pressure Injection System were reviewed.

anchers in the Unit 2 Auxiliary. Building was observed.
Inspection and test of support 2-538-2-0-436E-R3 was observed. Surveillance of the support had previously been completed. A support for a tray of copper tubing was attached to support 2-53B-2-0-436E-R3.
The surveillance as-bui,lt drawing for support 2-53B-2-0-436E-R3 did not report the above noted attachment.
Duke Power Company (DPC) procedure MP/0/A/3019/01, paragraph 11.3, note 3 requires that, "Any attachment (extra pipes, cable trays, extra steel,
,
.etc.) must be shown on the support / restraint design drawing". This appears to be in noncompliance of 10 CFR 50, Appendix "B",
Criterion V, as imple-mented by DPC Topical Report 1A, section 17.2.5, and Oconee Technical Specification Section 6.4.1.
This shall be identified as an example for Infraction 79-39-01 and 79-36-01-Failure to follow hanger inspection procedures.
Support 1-07A-400B-DE014, Plate "A", had been inspected and tested by the licensee.
The support was reported to contain wedge type concrete expan-sion anchors. A reinspection of the support was performed to verify com-pliance with licensee commitment and NRC IEB 79-02 requirements. During the reinspection, the inspector requested a torque check of the wedge type
'
concrete expansion anchors. Three of the four concrete expansion anchors for plate "A" of support 1-07A-400B-DE014 moved prior to reaching the test torque valve. DPC specification number OS-0020.00-00-003, paragraph 4.4.2 requires that wedge anchors shall have the proper test torque applied to ensure expansion of the anchor. This appears to be in noncompliance with 10 CFR 50, Appendix "B", Criterion V, as implemented by DPC Topical Report 1A, Section 17.2.5, and Oconee Technical Specification section 6.4.1.
This shall be identified as another example of Infraction 79-39-01 and 79-36-01-Failure to follow hanger inspection procedures.
6.
Seismic Analysis for As-Built Safety-Related Piping Systems-Work Activities and Records (Units 1 :nd 2)
In response to IEB 79-14, the licensee has initiated a surveillance program to verify that "as-built" safety-related piping systems are installed as seismically analyzed.
An inspection of licensee records and work activi-ties was conducted to verify compliance with licensee commitments and IE Bulletin 79-14 requirements. Unit.1 surveillance records for portions of system SIA and B in the Auxiliary Building and Containment Building were reviewed. Unit 2 surveillance records for portions of system 53B in the Auxiliary Building were reviewed. A portion of the Unit I system 51A piping inside the containment (shown on DPC drawing 0-492B-4) was rein-spected.
It was noted that hanger numbers 51A-0-479A-H21C and 51A-0-479A-H18C had attachments for supporting other piping. These attachments were not noted on the surveillance as-built design drawings.
It was also noted that a plate was in contact with the system 51A piping below the EL797'6" deck grating.
The plate appeared to restrict the movement of the pipe in the horizon *21 direction. The plate was not noted on the surveil-lance as-built design drawings. DPC procedure MP/0/A/3019/01, parsgraph 11.3,
~
note 3, requires that, "Any attachment (extra pipes, cable trays, extra steel, etc.) must be shown on the suppert/ restraint design drawing".

-3-Furthermore, DPC procedure MP/0/A/3019/01, paragraph 11.1.2 requires, "All locations where visual evidence of binding with an interference exists shall be reported on Attachment #2".
The above noted conditions of failing to follow procedure appear to be in noncompliance with 10 CFR 50, Appendix
"B", Criterion V, as implemented by DPC Topical Report 1A, section 17.2.5 and Oconee Technical Specification section 6.4.1.
This shall be identified as additional examples for Infraction 79-39-01 and 79-36-01-Failure to follow hanger inspection procedures.
