ENCLOSURE 1 NOTICE OF VIOLATION Georgia Power Company Docket No. 50-424 Vogtle License No. CPPR-108 During the Nuclear Regulatory Commission (NRC) inspection conducted on May 27 -
June 5,1986, violations of NRC requirements were identified.
The violations involved pipe supports design and construction.
In accordance with the " General Statement of Policy and Procedure for NRC Enforcement Actions," 10 CFR Part 2, Appendix C (1986), the violations are listed below:
A.
Criterion III of Appendix B to 10 CFR Part 50, as implemented by FSAR Chapter 17, Section 17.1.3 states:
"The design control measures shall provide for verifying or checking the adequacy of design, such as by the performance of design reviews...", also "... Design changes, including field changes, shall be subject to design control measures commensurate with those applied to the original design..."
Contrary to the above, the following design control problems were identified:
1.
Location of support V1-1202-001-H004 was 106 inches from its actual designed location. The tolerance in this case was eight inches.
2.
For the calculation of support V1-1204-028-H026, a design error was found. The dimension in the design calculation was consistent with the drawing, but not the field installation.
3.
In the design calculation packages V1-1204-028-H004, -H005, -006, two blocks are provided for approval signatures.
In several calculations, the second block was left unsigned, which hindered verification of proper signoff.
This is a Severity Level IV violation (Supplement 11.0). -
-B.
Criterion V of Appendix B to 10 CFR Part 50, as implemented by FSAR Chapter 17, Section 17.1.5 states:
" Activities affecting quality shall be prescribed by documented instructions, procedures, or drawings...
Instructions, procedures, or drawings shall include appropriate quantitative or qualitative acceptance criteria for determining that important activities have been satisfactorily accomplished."

Georgia Power Company Docket No. 50-424 Vogtle 2
License No. CPPR-108 Contrary to the above, the following procedures are inadequate. for the installation and inspection of spring hangers and snubbers.
1.
Pullman Power Products (PPP) Procedure IX-50, " Pipe Support Field Installation and Fabrication" was deficient in the installation and inspection of Bergan Patterson Spring Hangers as noted by the inspec-tion of Hangers VI-1302-025-H001 and V1-1205-010-H018, 2.
PPP Procedure IX-32, " Installation of Mechanical Shock Arrestors,".did not properly control the installation and inspection of snubber clamps or material verification of clamp bolting materials. This was noted in Support V1-1205-010-H017.
This is a Severity Level IV violation (Supplement II.D).
C.
Criterion X of Appendix B to 10 CFR Part 50, as implemented by FSAR Chapter 17, Section 17.1.10 states:
"A program for inspection of. activities affecting quality shall be established and executed by or for the organiza-tion performing the activity to verify conformance with the documented instructions, procedures, and drawings for accomplishing the activity..."
Contrary to the above, the following discrepancies were identified during an inspection of pipe supports:
1.
Location of four supports were outside of allowable tolerance per PPP Procedure IX-50.
2.
Weld lengths in two supports were less than those called out on the support drawings.
3.
Material for one item installed in a support was undersized beyond the tolerance allowed per PPP procedure IX-50.
4.
Gaps between supports and pipe were insufficient in three supports.
5.
Welds installed on a support were not specified on the support drawing.
6.
Installation of a strut was different than the drawing indicated.
7.
A dimension in a pipe support installation differed from the support drawing and calculation.
8.
Weld patterns called out on the drawings were different than these installed, caused by the unclear use of "TYP".
9.
Discrepancies between line designation list, piping and instrumentation diagram, and pipe isometric drawings were identified in four cases.
10.
Several inadequacies were noted in the documents included in the PPP QC packages for four supports.
Georgia Power Company Docket No. 50-424 Vogtle 3
License No. CPPR-108 This is a Severity Level IV violation (Supplement II.D).
Pursuant to the provisions of 10 CFR 2.201, Georgia Power Company is hereby required to submit to this Office within 30 days of the date of the letter transmitting this Notice a written statement or explanation in reply including (for each violation):
(1) admission or denial of the violation, (2) the reason for the violation if admitted, (3) the corrective steps which have been taken and the results achieved, (4) the corrective steps which will be taken to avoid further violations, and (5) the date when full compliance will be achieved.
Where good cause is shown, consideration will be given to extending the response time.
