(Closed) Unresolved Item (483/80-20-03)
Identified that cadwelding sleeves with vent holes for use in the horizontal position were installed in the vertical position. ERICO Products Company was contacted. The company verified that the sleeves used in either position are the same except for the vent holes. The company verified that the methods used to plug the vent holes when used in the vertical position were satisfactory.
Based on the information from the company, Daniel International Work Procedure WP-118 was changed to define how to use cadweld sleeves in altern-Le positions. Based on the information provided, the item is closed.
Functional or Program Areas Inspected 1.
Plant Tours One or more plant areas were toured several times during the reporting period to observe general construction practices; area cleanliness and storage condition of equipment. piping, and electrical cable.
2.
Drawing Control During the inspection period, six drawings were checked in the Auxiliary Building to determine if drawings of the latest revision were being used in the construction effort. Five drawings in the electrical area and one drawing in the heating ventilation and air conditioning area of work were checked.
It was found that all drawings were of the correct revision and change notices when issued were attached to the drawing.
No items of noncompliance or deviations were identified.
3.
Fabrications of Safety Related Piping Systems During the reporting period, the inspector observed work including a.
handling, protection, inspection, and welding of safety related piping systems.
(1) Feed Water System Welds 2AE-05-F037A (2) Fuel Pool Cooling and Clean-up System Welds
.2EC 02 FW0l6A 2EC 02 FWO18A
^
(3) Residual Heat Removal System Welds 2EJ 02 FW90-2EJ 04 F022A (4) Containment Cooling System Welds

.
(6) Essential Service Water System Welds 2EF 05 Fo45B (7) High Pressure Coolant Injection System Welds 2EM 01 F011B (8)
Steam Generator Blowdown System Welds BM 03 FWO45A
.
For each of these welds one or more of the following fabrication activities was observed. Handling and protection of piping and partially completed welds was satisfactory. Purge gas was correctly used. The weld area was free of any grease or particles. The joint fit-up dimensions were within procedural requirements and the welders were certified as qualified for the procedure specified to be used-for welding the pipe joint.
No items of noncompliance or deviations were identified.
4.
Piping System Nondestructive Testing
'
During the reporting period the inspector observed nondestructive a.
testing (Liquid Penetrant) of weld 2GN 01 FW13 in the Containment Cooling System.
(1)' The surface of the weld was satisfactory for the performance of liquid penetrant examination.
(2) The nondestructive test assigned met the code requirements.
(3) The technique was satisfactory and was performed by a qualified inspector.
No items of noncompliance or deviations were identified.
5.
Nuclear Steam System Supplier (NSSS) Equipment The inspector observed the inplace storage and protection of a.
NSSS components and piping. The piping assemblies, reactor
. vessel internals, and reactor vessel head is properly stored and protected.
b. LThe inspector observed the welding of a fillet welded locking device for bolts in the upper core internals. The welder was certified qualified for the weld performed.
No items of noncompliance or deviations were identified.

6.
Electrical Cable Installation During the reporting period, the inspector observed work including a.
installation, handling, and protection of electrical cable.
Speci-fica.
ssociated with this electrical cable pull was
"
obser (1) Cable Pull 2238 Cable 1GKI28AA For the pull the following activity was observed:
(1) a pull card was in use, (2) the cable was identified, (3) Quality control inspec-
'
tions were performed and Quality control pernonnel witnessed the pull.
b.
During the reporting period, the inspector obsecved work associated with the following cable terminations:
1NBB02AC 1NBB02AB INBB02AE 4NGB10AB 4 NEB 02AK 4 NEB 02AT 4NEK13AF-1GKH28CA
.The following conditions were observed:
(1) the cables were identified, (2) a work assignment sheet was in use, (3) crimping tools were calibrated,'(4) the person assigned was certified qual' ied to perform terminations, During a review of Deficiency Reports it was noticed that c.
Bachtel Drawing E-01013, Rev. 4 was being referenced as in-structions for repair of electrical cable jacket damage. Although the procedure provided by the drawing appears to be satisfactory, there is no technical evidence to indicate that a cable jacket repaired using the procedure will be returned to its original design characteristics or that qualification testing has been per-formed. Pending review of Bechtel data and/cr test results this will be an unresolved item.
(Item No. 483/81-02-01)
Regarding the cabic jacket repairs, there is also no control to ensure that the proper quality assurance is performed and documented during the repair. There is no procedure to define the craft and quality control personel responsibility, and to document the in-
'
- spections performed.

d.
During tours of the Control and Auxiliary Buildings several areas were identified to the Licensee where safety related cable in cable trays had construction materials and debrie placed on them.
This condition, and areas where violations existed, have been discussed during previous exit meetings. This is in violation of Daniel International Work Procedure WP-303 " Install ation of Wire and Cable".
c.
Paragraphs e and d above are examples of inadequate procedure and failure to follow existing procedures as required by Criterion V of 10 CFR 50, Appendix B.
.
This is an item of Noncompliance (Item No. 483/81-02-02)
7.
Concrete Placement a.
During the reporting period, concrete placement UC510540 of the Ultimate Heat Sink Cooling Tower was observed.
For the placement the following conditions were noted.
(1).The forms were secure, leak tight, and had been wetted prior to the placement.
(2) The preplacement inspection had been completed and was ir order.
(3) Quality Control inspectors were' assigned to each crew in addition to those assigned to perform periodic concrete testing.
(4) Adequate numbers of crews and personnel were assigned to make the placement.
(5) The placement was satisfactory.
No items of noncompliance or' deviations were identified.
8.
Fluid System Penetration Installation The inspector observed welding of penetration weld 2HD03F005. The weld area was free of foreign material and the welders were certified as qualified for the procedure specified.
No items of noncompliance or deviations were identified.
9.
Weldind Rod Control During the reporting period, weld rod issue trailer, outside the Turbine Building, was toured.
