Licensee Action on Previous Inspection Findings a.
(Closed) Violation 424/81-05-01: " Failure to Follow Welding Proceoure Purge Requirements". Georgia Power Company (GPC) letter of response dated June 8,1981 has been reviewed and determined to be acceptable by Region II. The inspector held discussions with the Construction Site Project Manager and examined the corrective actions as stated in the letter of response. The inspector concluded that GPC had determined , the full extent of the subject noncompliance, performed the necessary
- ~. .
survey and follow-up actions to correct the present conditions and developed the necessary corrective actions to preclude recurrence of similar circumstances. The corrective actions identified in the letter of response have been implemented, b.
(Closed) Violation 424,425/81-05-02: " Failure to Follow Storage Procedure Requirements". GPC letter of response dated June 8, 1981, has been reviewed and determined to be acceptable by Region II. Tha inspector held discussions with the Construction Site Project Manager and examined the corrective actions as stated in the letter of response. The inspector concluded that GPC had determined the full extent of the subject noncompliance, performed the necessary survey and follow-up actions to correct the present conditions and developed the necessary corrective actions to preclude recurrence of similar circum-stances.
The corrective actions identified in the letter of response have been implemented.

Unresolved Items Unresolved items are matters about which more information is required to determine whether they are acceptable or may involve violations or devia-tions. New unresolved items identified during this inspection are discussed in paragraphs 5.b and 6.b.(3).
5.
Independent Inspection Effort a.
Construction Progress The inspector conducted a general inspecti3n of the Units 1 and 2 containment construction sites, auxiliary building, and the piping assembly lay down yard to observe construction progress and construc-tion activities such as welding, nondestructive examination, material hand?ing and control, housekeeping and storage, b.
Storage During the general inspection of the lay down yard on October 6, 1981, the inspector noted the following conditions: - About fifty percent of the light bulbs associated with heater elements in approximately twenty HVAC air handling units were broken or not operating. The licensee indicated that bulb opera-tion is verified monthly.
, - The electrical control boxes for the HVAC units are attached to the outside of the units. The only protection from the weather is tight fitting plastic and tape.
At the time of this inspection, the following could not be determined:
. .- - -. .
- the cause and safety significance of such a large percentage of inoperable bulbs in a period of less than a month.
- the adequacy of the weather protection for the control boxes on the outside of the HVAC units.
The licensee indicated that they would look further into the matter.
The inspector stated that the above would be an unresolved item identi-
fied as 424,425/81-10-02: " Storage Controls for HVAC Air Handling Units".
Within the areas examined, no violations or deviations were identified.
6.
Steel Structures and Supports (Units 1 and 2) The inspector observed we', ding work activities for steel structures and supports as described below to determine whether applicable code and proce-dure requirements were being met.
The applicable code for containment fabrication is the ASME B&PV Code, Section III 1974 edition with addenda through summer 75, and Section VIII 1974 edition with addenda through summer 75. The applicable code for reactor coolant loop whip restraints is AWS D1.1-75.
The applicable code for pipe rack end connections is ASME B and PV Code 1977 edition with addenda through winter 1977.
a.
Welding (1) The following welds within the containment were examined in process to determine work conducted in accordance with traveler; welding procedures available; welding technique and sequence; weld geometry; fit-up; electrical characteristics; equipment condition: Structure Unit LocationIdentification Containment

40038-6-1M1A Whip Restraint Reactor Coolant
40038-6-1M1B Whip Restraint (2) The following welds outside the containment were examined in process to determine work conducted in accordance with travelers; welding procedures available; welding technique and sequence; weld geometry; fit-up; electrical characteristics; equipment condition: Structure Unit Location / Identification hpe Rack End
R-5180 Connection dith regard to the above inspection, the inspector noted on October 6,1981 the following conditions: (a) Red pencil had been used to mark fit-up locations for pipe rack end connections in the weld prep area and subsequently welded over.
The above is contrary to PPP procedure X-18, dated April 24,1981, " Field Welding Inspection", paragraph 6.1.2 which requires visual inspection prior to welding to assure rust, grease, scale or any other foreign material has been removed from the weld preps. Therefore, preweld inspec-tion bad not been made in the above area.
(b) Damaged electrodes and electrode stubs were discarded in a trash container not autnorized for electrode disposal. The above is contrary to GPC procedure CD-T-14, Revision 2, " Receipt, Storage and Control of Welding Materials", para-graph V.E which requires damaged electrodes and electrode
- - . .
stubs to be returned to properly designated weld rod scrap containers. Therefore, weld material control procedures were not followed.
The above examples indicate inadequate measures tc control 'iing.
Failure to establish adequate measures to control 2ps.ial processes including welding is in violation of 10 CFR 50 Appendix B, Criterion IX. The above violation will be identified as 424,425/81-10-01: " Failure to Control Welding".
b.
Welder Qualification The inspector reviewed the CB&I program for qualification of welders and welding opeators for compliance with QA procedures and ASME Code requirements. The applicable Code for welding qualification is ASME B&PV Code Section IX as invoked by GPC Specifications X2AG06 Rev. 4 and X4AZ01, Section P.1.
(1) The following welder qualification status records and " Records of Performance Qualification Test" were reviewed relative to the weld joints listed in paragraph 6.a.(1).

.. ., ,
, With regard to the above inspection, the inspector, on October 6, 1981, noted that the density of the performance qualification radiographs for JCB was 1.54 to 1.70 not 2.0 minimum as required by the C8&I program.
The CB&I QA Superintendent stated that radiographs with acceptable film quality of the test assemblies in question had been sent to CB&I's Birmingham, Alabama office. The licensee stated that they had not reviewed any onsite welder qualification test assembly radiographs.
However, the licensee further stated that they had reviewed the raJiographs of the first ten feet of weld for each welder.
The licensee indicated that they would look further into the matter.
The inspector stated that the above would be identified as unresolved item 424,425/81-10-03: " Welder Qualification Film Density".
c.
Welding Filler Material Control The inspector reviewed the CB&I program for control of welding materials to detemrine whether materials are being purchased, accepted, stored, and handled in accordance with QA procedures and applicable code requirements. The following specific areas were examined: - Purchasing procedure, receiving, storing, distributing and hand-ling procedures, material identification Welding material purchasing and receiving records for the - following materials were reviewed for conformance with applicable code requirements: , Type Size Control No.
7018 3/32" RRR-087 1018 5/32" CC-051 7018 1/8" ZZZ-084 EM121C 3/32" 0891189 7018 3/16" RRR-079 F72 FLUX 0292 F72 FLUX K-317 Within the areas examined no violations or deviations were identified except as described in paragraph 6.a.(2).
