Licensee Action on Previous Enforcement Matters a.
(Closed) Unresolved Item 424,425/8E -10-04 : " Purge Gas For Storage of Components." This item concerns the adequacy of controls for storage purge gas moisture.
The licensee has provided the needed moisture controls in Revision 2 of MI-T-03, " Mechanical Equipment Purging." The inspectors have no further questions in this area.
b.
(Closed) Violation 424,425/81-14-02: " Welding Procedure Inadequacies."
Georgia Power Company's letter of response dated February 12, 1982, has been reviewed and determined to be acceptable by Region II.
The inspectors held discussions with the QA Site Supervisor and examined the corrective actions as stated in the letter of response.
The inspectors concluded that Georgia Power Company had determined the full extent of the subject violation, 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.
4.
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 6d(1) and 6d(2).
5.
Independent Inspection Effort Construction Progress The inspectors conducted a general inspection of the Unit I and 2 auxiliary buildings and containments to observe c.onstruction progress and construction activities such as welding, material handling and control, housekeeping and storage.
Within the areas examined no violations or deviations were noted.
6.
Steel Structures and Supports (Units 1 and 2)
The inspectors observed welding 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 fof 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 inspectors observed in process welding activities of structural field welds as described below to determine whether applicable code and procedure requirements were being met.

Visual Inspection of Welds (55155 and 55053)
The inse... ors visually examined completed and accepted welds as described below to determine whether applicable code and procedure requirements were being met.
(1) The below listed welds were' examined relative to the following:
location, length, size and shape; weld surface finish and appear-ance (including inside diameter of pipe welds when accessible);
transitions between different wall thicknesses; weld reinforce-ment -- height and appearance; joint configuration of permanent attachments and structural supports; removal of temporary attach-ments; arc strikes and weld spatter; finish grinding or machining of weld surface -- surface finish and absence of wall thinning; surface defects -- cracks, laps, and lack of penetration, lack of fusion, porosity, slag, oxide film and undercut exceeding prescribed limits.

Radiography (55053)
(1) The inspectors reviewed CB&I procedure RTIN Rev.4 " Radiographic Examination Procedure for Welds - Containment Liners and Class MC Components" to ascertain whether it had been reviewed and approved consistent with the licensee's established procedures.
NDE procedure RTIN was reviewed for technical adequacy relative to ASME B&PV Code,Section V, 74S75 edition, and other licensee commitments / requirements, in the below listed areas.
-
Material and weld surface condition requirements (irregu-larities, weld ripples, surface finish, etc.).
-
Radiographic film processing requirements.
-
Outlity of radiographs - limits on mechanical, chemical or other blemishes, such as fogging, process marks, scratches, finger marks, loss of detail or false indications.
-
Film density limits for single and composite viewing.
-
Use of densitometers for assuring compliance with film density requirements.

With regard to the inspection above, the inspectors noted that CB&I procedure RTIN, Rev. 4 referenced ASME Section V Article 3.
At the time of this inspection the basis for the Article 3 reference could not be determined.
Pending the determination of the be. sis for tne Article 3 reference and
review by NRC, this matter will be identified as unresolved item 424,
425/82-23 - 01: " Article 3 Basis".
(2) The inspectors examined the below listed radiographs to determine whether radiographic examination was performed in accordance with the applicable procedure. This examination was made in the areas listed in paragraph 6d(1).

Safety-Related Pipe Support and Restraint Systems (Units 1 & 2) (500908)
The applicable code for safety-related support and restraint installation is the ASME Boiler and Pressure Vessel Code,Section III, Subsection NF,1977 Edition plus addenda through summer 1978. The inspectors cbserved various activities associated with the installation of supports and restraint to determine if code and procedure requirements were being met..The inspectors reviewed the following work procedures pertaining to safety-related pipe support and restraint systems whether they were approved by authorized licensee personnel.

To assure that the type and classification of pipe support and restraint systems comply with approved drawings and or specifications, the inspectors examined the following hangers:
HANGER APPROVED COMPLIANCE WITH COMPLIANCE WITH DRAWING NO STRESS ISOMETRIC SPECIFICATION
,
V1-1210-011-H008 Rev. 0 yes
"
V1-1208-003-H107 Rev. 3 yes yes
- The corresponding isometric No.1K3-1210-160-01 Rev. 2 as of 10/1/82 was not revised to show Hanger No. V1-1210-011-H008.
Drawing Change Notice DCN 1 te BPC drawing 1K3-1210-160-01 Rev. 2 was initiated by BPC Los Angeles office on 9/21/82 for the above hanger. The inspectors informed the licensee that they wanted to follow the progress of the above hanger documentation pending the incorporation of DCN 1 in drawing 1K3-1210-160-01. This matter will be identified as inspector followup item 424/82-23-03: " Hanger Documentation".
-
The location and spacing of Hanger No. V1-1208-003-H017 Rev. 3 and the corresponding stress isometric No.1K3-1208-003-01 Rev.10 were examined and found acceptable within code requirements.
During this inspection the inspectors reviewed QC Hanger Inspection Check-list and found that the list did not specify the verification of bolt type and size. Pullman Power Products agreed that the inspection checklist will be revised to reflect the changes.
Pending the checklist revisiens, this matter will be identified as inspector followup item 424,425/82-23-04:
" Hanger Inspection Procedure Revision".
In the area of dynamic pipe supports, the inspectors examined six (6)
mechanical type snubbers, checked shaf.t travel for smoothness by simulating normal operation by pulling and pushing the snubber shaft; also simulated unit activiation by sudden movement. Hangers observed in the warehouse were as follows:
Snubber Model Hanger No.
Observation Results PSA -3 V1-1206-002-H002 Acceptable (Design Load =6000#)
V2-1205-003-H014 Acceptable PSA-1 V1-1206-006-H020 Acceptable (Design Load =1500#)
V2-1205-009-H014 Acceptable PSA-V1-1208-240-H008 Acceptable (Design Load =650#)
V1-1208-241-H005 Acceptable In addition, the inspectors selected three (3) spring hangers and observed minimum requiraments for hanger rod size, examined spring hanger indicators which show the approximate " hot" and " cold" position of the piping system.

Inspector Followup Items (Closed) 424,425/82-05-06: " Control of Grinding Particles in Piping". This item concerned inadequate controls on piping cleanliness. The licensee has revised PPP Procedure XIII-4, " Cleaning Procedure (Field)" on April 15, 1982, to correct the inadequacies. The inspectors have no further questions in this area.
