"denotes those persons present at the exit interview.
Other craftsmen and technicians were interviewed as necessary when the inspection interfaced with their work.
Plant Tour The inspector observed work activities in progress, completed work and plant status in several areas of the plant during a general inspection of Units 1 and 2.
The inspector examined work items for obvious defects or noncompliance with NRC requirements or licensee commitments.
Particular
note was taken regarding the presence of quality control inspectors and indications of qual'ity control activities.
In addition, the inspector interviewed craft and supervisory personnel encountered in the work area.
Specific work in progress and completed work observed by the inspector included lay-up of Unit 2 RHR heat exchanger, equipment in receiving and
"hold" areas of the'warehouse; laydown area storage, storage 'of pipe supports and restraints, electrical and instrumentation equipment installation.
The
'inspector questioned installation of a temperature sensing element as discussed in paragraph 3 below.
No items of noncompliance were identified.
ualification of Tem erature Sensin Element Su ort r
During the facility inspection, the inspector observed that the ambient
. temperature monitor (TE-15799A) installation in the Unit 1 drywell did not appear rig'id enough to withstand a seismic event and perform its intended function.
The thermo-element support bracket consisted of a 1/8 inch thick
- stainless steel right angle bracket bolted to a welded unistrut wall support plate.
The licensee stated that these Sensor Assemblies (Identified in Vendor Drawing H33205-4104, =Revision D) were supplied with the installed bracket and that the manufacturer had qualified the installation assembly.
The inspector reviewed-the manufacturer's test report (RMT-57510) and found that the report which had been approved by Bechtel., does not meet the device qualification test requirement of Section 4e nor the documentation require-ment of Section 7 of the purchase specification 8856-J-800.
The licensee furnished the inspector. additional data in the form of a Supplier Deviation Disposition Request (SDDR) 8003 dated November 15, 1979 on the requirement for a Registered Professional Engineer signature and a
reply to the manufacturer dated October 27, 1980 stating it had rejected the SDDR 8003 deviation request.
This item is unresolved pending NRC review of licensee resolution (050-387/81-01; 050"388/81"Ol"Ol).
Electrical Cable and Terminations - Mork Observation The inspector examined work performance, partially completed work and completed work pertaining to the installation of 480V and 4160V cable to determine whether the requirements of applicable specifications, work procedures, drawings and instructions have been met in areas relating to installation, routing', termination and inspectio a.
Items examined for this determination include:
Specifications E-49, E-59, E-60, E10 and E-396.
Cable Scheme. Numbers CP1D0020M, LP1Y0109M, MKlK0212C, HK1K0212D, CPlB053G and CPlB0503H.
Panel No.
1B230LC (Unit 1):
Cable Raceway E1PJ81.
Cable Conduit ClP007, ElP154 and E10155.
- The inspector observed that exposed cables from conduit E1P154 and ElP155 were routed through Cable Tray E10J81 then into Panel No.
, 1B230LC adjacent to conduit ClP007.
There was no separation or barrier between the exposed cable (color code red) and the conduit (color code, orange).
Inspection data was not available at the time of the exit
'nterview to indicate status.
The licensee stated that the separation problem would have been identified in the final inspection and that they had a field procedure (E-10) for accomplishing this task.
The inspector reviewed the field procedure E-10 and found that the procedure does not address separation requirements external to panels/
equipment.
The licensee agreed to revise the field procedure to include separation criteria requirements external to panels/equipment up to the first raceway.
This item is unresolved pending NRC review of licensee procedural changes to ensure all separation.requirements are adhered to and/or justified (050-387/81-01-03).
b.
Items examined for this determination include:
Cable No.
FP2B0504C in Panel No.
2B24021 Cable No's FP2B0504ABC in Panel No.
2B24601 The inspector observed that the cable adjacent to FP2B0504C in panel 2B24021 was not lableled.
Discussions with gC personnel and a search of inspection records indicate the above cable installation had not been inspecte Item 6 of the equality Control Instructions (gCI) E-5.0, Revision 3, dated October 9, 1979 states, in part, that:
"All specialized termin-ations shall have their applicable final inspection activities performed prior to becoming inaccessible for visual inspection due to progression of construction.
Specialized terminations being terminations requiring shrink tubing...tapeing...".
Section 3.3 of gCI-E5.0 requires veri-fication that cable stripping does not nick, scrape or damage wiring.
The licensee was informed that this was in noncompliance with 10 CFR 50, Appendix B, Criterion V in that the cables were terminated, taped and bolted to the respective bus without prior inspection as required in gCI E-5. 0 (050-388/81-01-03).
5.
Electrical (Com onent and S stem) - Work Observation The inspector examined work performance relating to gA Surveillance Audit SSES (CL-37) dated October 30 through December 12, 1980 to determine whether deficiencies identified during the audit were corrected and that the correc-tive action precludes recurrence.
Equipment identified in the audit and examined January 6, 1981 for this determination include:
=
Panels 2C-038, 2C226B and 2C-227B at elevation 719'-0", Area 33.
Panel 2C-038 was found to contain excessive amounts of dirt and debris in the form of paper cups, scrap tubing and scrap wire.
Panel 2C-226B was found to be without heat.
The applications of heat internally to equipment. was identified as a deficiency which had been corrected following the audit report.
Discussions with the licensee, construction personnel and a review of the applicable maintenance requirements indicate the inspection requirements consist of a monthly inspection of the equipment cover for repairs and availability of internal heat.
(The last inspection of the above listed panels was conducted December 16, 1980.)
In addition, the daily walk-through inspection initiated by gC and Field Engineering Personnel in response to MCAR-1-26 had been discontinued.
On January 7, 1981 the licensee issued a memo re-instituting the daily walk-through inspections.
This item is unresolved pending NRC evaluation and verification of sur-veil 1 ance program (050-387/81-01-02; 050-388/81-01-02).
