2. Ins'trument Component t
and Systems Work Observation
'
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.

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

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.
d. 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. This activity was conducted from header '

(Root) valve V-872 to safety-related valves UY648 (Solenoid) and
UV648 (Control) located in the safety injection system. The
following drawings and specifications were utilized for verification
of the valves and associated air lines:
(4) Drawing No. 13-M-SIP-002 Revision 11, " Safety Injection and
Shutdown Cooling System"
~
(5) Drawing No. 13-P-SIF-103 Revision 17, " Containment Building

. 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.
3. Exit Meeting
The inspector met with licensee management representatives denoted in
paragraph 1 on August 15, 1985. The scope of the inspection and the
inspector's findings as noted in this report. were discussed.
