a.
' Receiving Inspection
_
'
No safety-related iastrument components were received during this
-
inspection'.. The. inspector conducted a' detailed inspectica of receiving and storage activities during March 1981; this is
~
-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 for.
-
evidence that receiving inspection was performed for the installed
'
instrument components identified in.Section 2.c of this report. The folle.ing Material' Receiving Reports (MRRs) were reviewed.

Receiving inspections was performed for damage, storage classification, identification and marking, and documents received.
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 documentation.
b.
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 designations.
(2) Components are properly identified.
(3) Storage conditions (temperature, humidity, cleanliness, etc.)
are controlled and monitored.
(4) Nonconforming items are identified and segregated.
(5) An adequate number of qualified personnel are available to perform.the; required storage function.
c.

Inspection of the installed instruments' revealed the following:
(1) A11' instruments were as specified on the design drawings.
s (2) Instruments were correctly and permanently identified.
(3) Instruments were not exposed to potential hazards such as high-pressure piping or flammable material.
(4)= Physical and electrical independence between redundant parts were properly maintained.
Two of the instruments selected for this inspection were recently removed. Pressure transmitter number RCA-PT-101A was removed for rework in accordance with NCR No. JC-1065. Review of this NCR

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 another.
In this instance MCN-60196-J was issued to obtain a replacement pressure transmitter from Unit 3 for use in Unit 2.

Construction Testing and Calibration This activity is no longer being performed by construction. All testing and calibration activities are done by the startup group.
e.
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. discovered.
In addition ~to the above equipment inspection, the inspector performed a lwalkdown inspection of approximately 45 feet of

. Instrument air tubing is' field routed which means that the tubing is installed from' support to-support at the discretion of the field engineer as long as the' installation is in accordance with the requirements contained in the above drawings and specifications.
Attributes verified were minimum length of the unistrut supports, embedment. length, minimum weld length, and where applicable, the anchor bolt spacing distance. The safety-related valves were correctly identified and located in accordance with the construction drawings.
No violations of NRC requirements or deviations were identified.
