-documented in NRC Report Nos. 50-529/85-13 and 50-530/85-06.~ To assure that~the administrative controls were currently being affectively implemente'd the; inspector observed receiving inspection activities. . Components were'being properly identified, nonconforming components ccutrolled, and an adequate number of qualified personnel were available- to perform the receiving inspection functicn. The inspector-reviewed the quality records fo evidence that receiving inspection was performed for the installed instrument components identified in.Section 2.c of this report. The '

Receiving inspections was performed for damage, storage classification, identification and marking, and documents receive A nonconformance report was written on MRRs 116567 and 168416 (NCR No. 1203) for documentation not received. This NCR was subsequently closed upon receipt of the documentatio Storage None of the type of instrumentation selected for this inspe tion were located in storage. However, observation and evaluation of storage activities for. Other safety-related instrument components revealed the-following:

(1) Instruments are stored in proper storage level designation (2) Components are properly identifie (3) Storage conditions (temperature, humidity, cleanliness, etc.)

are controlled and monitore (4) Nonconforming items are identified and segregate (5) An adequate number of qualified personnel are available to perform.the; required storage functio Completed Work The following installed instruments were selected for inspection:

o revealed that the instrument was returned to the vendor for recertification in response to a 10 CFR Part 21 report. Pressure transmitter RCD-PT-101D was removed as a result of a Material Change Notice (MCN) No. 60196-J. The MCN is the controlling mechanism utilized to transfer material and equipment from one unit to anothe In this instance MCN-60196-J was issued to obtain a replacement pressure transmitter from Unit 3 for use in Unit Construction Testing and Calibration This activity is no longer being performed by construction. All testing and calibration activities are done by the startup grou Instrument Air System The instrument air system is not safety-related; however, it is important to safety because instrument air is used for safety-related control components. The major component of the instrument air system selected for inspection was an air compressor identified as IAN-COIC, R2T. The inspector utilized the following design / installation drawings to verify proper location and

'

installation of the air compressor:

(1) Drawing No. 13-M-IAP-001 Revision 13, "P&ID Diagram Instrument and Service Air System" (2) Drawing No. 13-P-ZTL-401 Revision 5, " Equipment Locations Turbine Building Plan"

,

(3) Drawing No. 13-C-ZTS-101 Revision 22, " Turbine Building Foundation Mat Plan Area TIA, B&C" The inspector observed that the air compressor was correctly and permanently identified. In addition, the inspector was able to verify correct location and configuration of the air compressor, including anchor bolt locations, by performing physical measurements within the Turbine Building. The air compressor was correctly and permanently identified.

'

The inspector reviewed the inspection reports, called CIPs (Construction Inspection Planning) associated with installation of the air compressor. The CIP of May 21, 1981, was for inspection of equipment installation which covered installation of anchor bolts, and equipment location and orientation. Angular alignment and i offset (parallel) alignment was performed and documented on CIP of August 25, 1981. An additional CIP was initiated on May 17, 1984, for equipment inspection as a result of internal corrosion being discovered in the Unit.2 air compressors. CIP No. 156.0-301 was written for. inspection of Unit 3 air compressors for evidence of corrosion; no' corrosion was. discovere In addition ~to the above equipment inspection, the inspector !

performed a lwalkdown inspection of approximately 45 feet of .

instrument air; tubing. This activity was conducted from header '
