Areas Inspected: Routine inspection by the IE Regional Resident Inspec-tor (RI) of safety-related construction activities including protection of the reactor vessel and other components of the nuclear steam system supplier; (NSSS), work on the core internal instrument tubes; material lay down and storage areas; electrical work; welding of reactor coolant system and safety-related fluid system piping; drawing control; storage of aggregate, and cement and testing of concrete test cylinders. This inspection involved 96 inspector-hours by one NRC inspector.
Results: Of the areas inspected, one item of noncompliance was identified (deficiency) failure to assure that electrical components stored in place are properly protected from damage or deterioration.

Functional or Program Areas Inspected 1.
Plant Tours One or more plant areas were toured several times each week during the reporting period to observe general construction practices; area cleanliness and storage condition of equipment, piping, and cable.
Two tours were made on back shifts of work.
No items of noncompliance or deviations were identified.
2.
Concrete Batch Plant and Test Laboratory Operation The inspector observed the storage of aggregate, admixes, and cement.
The cement and admixes were properly protected from the environment.

The inspector observed the preparation and testing of concrete cylin-ders. The cylinders were properly marked and capped and tested. Con-crete test cylinder #6863 and #6864 of Pour ZC631 503 were tested.
No items of noncompliance or deviations were identified.
3.
Drawing Control During the inspection period, 20 drawings were selected in the Con-
,
tainment Building to determine if drawings of the latest revision were being used in the construction effort. All drawings were found to be of the correct revision.
>
No items of noncompliance or deviations were identified.
4.
Fabrication of Reactor Coolant Pressure Boundary and Safety Related Piping Systems During the reporting period, the inspector observed work a.
including handling, protection, inspection, and welding of reactor coolant boundary and safety-related piping systems.
Specifically, work associated with these joints was observed; (1) Reactor Coolant System 2BB-01-F106 2BB-01-F107 2BB-01-F108 (2) Chemical and Volume Control System 2BG-22-FWO57 2BG-21-F008 2BG-01-FW109 (3) Component Cooling Water System 2BG-13-F021 (4) Accumulator Safety Injection System 2EP-01-F0004 (5) Essential Service Water 2BF-08-FW-1 (6) Residual lleat Removal

(7) High Pressure Coolant Injection 2EM-03-F013 (a) 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 joint fit-up dimensions were within procedural requirements and the weld area was free of any grease or particles of tools such as grinders, brushes, and files were properly color codes for use on stainless steel.
Welders were certified as qualified for the procedure specified to be used for welding the pipe joint.
(b) During the reporting period, the inspector observed the liquid penetrant test of the longitudinal seam weld in spool S002 near joint F004 shown on Drawing M03EP-01 Revision 6.
The weld had been ground smooth as part I
of the disposition of Deficiency Report 2SD-0699-P in November 19.
The results of the test indicated that there was no crack within the test area. The test area consisted of the weld, the metal extended from the face of the pipe back into the pipe for approxi-mately 12 inches. The liquid penetrant technique used to perform the examination was satisfactory.
(c) During the reporting period, the inspector observed the radiographic test of an incore instrument joint.
The radiation protection techniques were satisfactory.
No items of noncompliance or deviations were identified.
5.
Material Storage During the reporting period the storage areas for reinforcing steel and other steel material, and electrical cable was observed. The steel material was orderly and placed on wood beams off the ground.
The electrical cable spools were stored off the ground and cable ends were taped and protected from moisture.
It was noted that much of the cable is manufactured by Rockbestos Company.
Based on reports that some Rockbestos electrical cable has been spliced, the licensee was requested to determine if splices might also exist in cable that has been purchased and in-stalled at Callaway. This is an unresolved item.
(483/80-15-01)
No items of noncompliance or deviations were identified.

6.
Electrical Component Anchoring During the reporting period the inspector reviewed the anchoring of the battery racks. The layout for 60 cell MCX-1650 battery ON-2-507-074530-816 racks were checked.
Plug weld location and size relative to the four battery racks were sampled. The layout meets the requirements of Gould DWG 063349D.
No items of noncompliance or deviations were identified.
7.
Welding Rod Control During the reporting period, weld rod issue stations in the Turbine Building and outside the trailer were toured.
It was determined that (1) the records are properly kept; (2) welding materials are properly identified and segregated; (3) the temperature of the rod ovens is maintained.
No items of noncompliance or deviations were identified.
8.
Electrical Cable Installation (a) During the' reporting period, the inspector observed work in-cluding installation, handling, and protection of electrical cables. Specifically, work associated with these electrical cable pulls was observed:
(1) Cable Pull 0246 Cables 1SAZ 03AA ISAZ 03BA ISAZ 14AA ISAZ 14EA 1EPK 02FB IEPR 08CA 1EPR 08BA (2) Cable Pull 0260 Cables ISAZ 11BA IGNG 02CD 1GNG 02CH (b) During the reporting period the condition of electrical cabinets stored in place was observed.
Generally, the panels and cabinets have covers intact and are protected by a clear plastic covering.
Several, however, where work had been performed, did not have the access plates reinstalled and were not recovered with a plastic dust and vapor barrier.

Panel Number NB0209, and NG01A had closures that had not been installed for several days. Access doors were unlatched in panel 2NG01, 2NG04, 2NG02A, and cabinets 2NK22, 2NK23,-2NK24, and NG04C were not covered with a dust and vapor barrier.
American National Standard N45.2.2 (ANSI N45.2.2) paragraph 6.4.2 states that, " covers removed for internal access at any time for any reason shall be immediately replaced after completion of the purpose for removal." The Preliminary Safety Analysis Report paragraph 3.12 states that ANSI N45.2.2 will be complied with during the construction and operation of Callaway.
Daniel International administrative procedure AP-IV-09 paragraph 3.6 requires that maintenance at a minimum meet the requirements of ANSI N45.2.2. Since the electrical panels have not beem maintained in accordance with the foregoing requirements, this is an item of noncompliance. (483/80-15-02)
Items of noncompliance or deviations are as indicated above.
Unresolved Items Unresolved items are matters about which more information is required in order to ascertain whether they are acceptable items, items of noncompli-ance, or deviations. One unresolved item disclosed during this inspection is discussed in paragraph 5.
Exit Meetings The inspector met with licensee representatives (denoted under Persons Contacted) on May 8, 15, 22, and 30, 1980. The inspector summarized the scope and findings of the inspection performed. The licensee representa-tives acknowledged the findings reported in previous paragraphs.
