Recei t Stora e and Handlin of E ui ment and Materials - Unit 2 The inspector conducted a detailed inspection of warehouses to assure that the administrative controls for storage of safety-related items were being properly implemented.
The warehouses inspected were the Water Reclamation Facility, the Main Warehouse, and Warehouse C.
There are no offsite warehouses.
The storage level requirements and environmental conditions were in accordance with ANSI N45.2.2.
There were no safety-related'tems classified to Level A; most items, including Level C
items, were classified,to Level B which is satisfactory since Level B's the higher level designation.
Access control, identification of items, designated.hold'reas, and cleanliness were properly maintaine g4 I
2.
The Material Control Department conducts monthly inspections of the warehouses, and documents this activity in the Storage Verification Report.
These inspections are performed to assure that controlled conditions are being maintained.
The inspector reviewed reports generated
.from October 1984 through February 1985.
The reports were satisfactory with no evidence of previous identified NRC concerns regarding approvals, who performed the inspection, or identification of the warehouse inspected.
Material Control also reports on a weekly basis the shelf life of stored materials.
The inspector verified that maintenance was notified of items stored in the warehouse requiring, preventative maintenance.
This was accomplished in accordance with
"Department Instruction for the Notification of the Maintenance Control Center (MCC) for Material Placed'n Storage that Requires Preventative Maintenance" per memo of November ll, 1984.
The inspector reviewed the following Material, Handling and Storage procedures, which have recently been approved or revised, and verified implementation of specific areas:
a
~
12AC-OZZOl "Inventory Control",.Procedure Change Notice (PCN) Ol of 9/8/84 and PCN 02 of 2/11/85.
The procedure requires that a Data Capture Sheet (DCS) be used to provide traceability and accountability of received materials.
The inspector reviewed a
number of DCS forms to verify that the Safety 'Section, Radiation Section, or the Metrology Lab, had indicated their review of the items received when required.
This review was evident on the DCS forms examined by the inspector.
b.
3N513.15.00 "Material Receiving", Revision 0 of 9/17/84.
Material Control visually inspects all shipments in accordance with Department Operating Instructions and subsequently places a
Receiving Label on each item received.
The inspector randomly selected
.a number of received items and confirmed that the Receiving Labels were on the items, and properly fi:lied out with the required signatures.
c.
3N513.23.00 Transferring Material and Equipment" Revision 0 of 9/17/84.
The inspector verify that material transfer from. the Main Warehouse to Warehouse C was in accordance with this procedure.
d.
3N513.23.00 "Control of Over, Short and Damaged Material", Revision 0 of 9/17/84.
The inspector reviewed a number of Reports of Unsatisfactory, Over, Short and Damaged Material, in order to determine if any potential problems exist on replacement of
.safety-related items.
No apparent problems were identified from these reports.
Interviews with receiving personnel revealed no potential problems or concerns.
The following items, recently purchased,,and received on-site, were inspected to verify that receipt inspections, di'spositions and'torage requirements were in accordance with established administrative controls:
Purchase Order No.

The inspector verified that administrative controls for nonconforming items were properly implemented including marking, segregation, disposition and documentation.
Provisions were established to assure that Vendor (}uality is notified of nonconforming items.
Also, there are provisions to assure that repaired or reworked items are inspected in accordance with applicable procedures.
No violations of NRC requirements or deviations were identified.

~
Observation of Meldin Activities Within Containment The inspector observed in-process structural welding activities within the Unit 3 containment building to assure that welding was performed in accordance to the AWS Dl.l "Structural Welding Code".
This was accomplished by visual examination of welding associated with the following steel structures and supports:
(1)
SS-004.
(2)
RD-053 (3)
RC-003 (4)
SI-130 (5)
SI-130 (6)
CS-513 Hanger H
(Fillet Weld)
Hanger A
(Fillet Meld)
Hanger A
(Flare Bevel/Fillet Weld)
Hanger
(Fillet Weld)
Hanger
(Fillet Weld)
Hiscellaneous Steel Plate (Single Bevel Groove Weld)
Prior to welding of the assembled parts, the inspector examined the following conditions to verify conformity to the applicable specifications:
(1)
Meld joint geometry, preparation and finish.
(2)
Fit-up 'and alignment.
(3)
Cleanliness.
During in-process welding operations the following verifications were performed by the inspector:
il
!
(1) Welding procedures and, drawings were available.
(2)
Welder technique and sequence in accordance with the welding procedure.
(3)
Melding filler metals of the specified type and grade.
(4)
Interpass chipping, grinding and controls performed in accordance with applicable procedures.
(5)
Melding electrodes used in the positions and with the electrical characteristics specified in,the welding procedure.
(6)
Welding equipment, including power cables, in good condition.
b.
Welder uglification The inspector reviewed the qualification records of the six welders involved in the welding operations observed during this inspection.
All were satisfactory qualified to weld under the respective welding procedures according to documents reviewed which conformed to AWS Dl.l requirements.
The inspector also observed the completion of a welder qualification test, plate used for qualifying a welder for unlimited thickness.
The joint detail, plate dimensions and preparation for radiographic examination were in accordance with AMS Dl.l qualification test requirements.
c ~
Weldin Procedure S ecification The inspector examined Bechtel welding. procedure number Pl-A-Lh (Structural) Revision 3, Amendment 5 of April 1, 1984.
'This welding procedure
, utilized on the welding observed during this inspection,.
met all the requirements specified in the AMS Dl.l'ode.
d.
Visual Examination of Weld The inspector visually examined the following structural welds for compliance to AMS Dl.l Code:

RC-161 Hanger C
(6)
SG-180 Hanger AB (7)
CH-152 Hanger G
(8)
CH-227 Hanger C
Also examined were clips welded to structural beams at various locations.
