Subject:
Request for Information on Employee Survey
Dear Mr. Spence:
The NRC Comanche Peak Intimidation Panel has identified the need for information about employee surveys conducted in 1979 and 1983, to determine the conditions under which these surveys were administered. Please provide responses to the following questions to assist the panel in its evaluation effort.
1.
What were employees told concerning the confidentiality of their responses, who would be seeing the results, and how the survey data would be used?
2.
How were the surveys introduced and passed out to employees?
3.
Where and how did employees complete the surveys?
4.
What guidelines were used by those transcribing employee responses?
5.
How were the completed surveys returned to management.
6.
How were employees selected to participate?
7.
Which organizational units and/or job categories were included and excluded from the suneys and what criteria were used for this process?
8.
How many QC inspectors were employed at the plant when each of these two surveys were taken?

The practice of butt splicing cables in panels was allowed on a limited ba:is, as specifed in Section 8.1.5.2.4 of Amendment 44 to the Final safety Analysis Report (FSAR). The NRC staff. reviewed Texas Utili-3 7.ies Electric Company's (TUEC's) justification for permitting butt splices 4
inside panels (correspondence from M. Srinivasan, NRC Power Systems Branch to B. J. Youngb1 cod, NRC Licensing Branch, July 30,1984), and concluded that the practice is acceptable on a limited basis, subject to the fol-
'cwing conditions:

The TRT found the splices to be in conformance with all precedural requirements set forth by TUGC0 which did not include the tnree conditions for acceptability stated above, which the NRC considers important to assure the adequacy of these splices, with the following exception.] All r
enhie insula-gplices inspected were missing the " nuclear _h_ eat-shrink =hla tion sieeves," as requfied by paragraph 3.2.15 of the procedure for
/
DUD-volt control and instrumentation connections. Due to this recurrent condition, the TRT reviewed the QC inspection reports for 12 butt splices and found the following:

Six of the nine incorrect forms contained handwritten notes by the i/ inspector indicating that he hadl witnessed the spliceH however, no reference was added to indicate that sne installation of the heat-shrinkable sleeves was required to be witnessed.

This lack of awareness of where the heat-shrinkable sleeves should be installed, as reflected in the CC inspection fcrs, when coupled with the high percentage of missed and/or improperly documented inspecticns requiring witnessing, indicated that craft and inspec fon This personnel lacked f amiliarity with these procedural requirements.

Characterization: It is alleged that:
ECables were spliced in cable trays in the cable spreading room i-A iolation of regulatory requirements (AE-50).
C.ble Solices in Raceways. Al.le'gation AE-50 involved tihe alleged splicing ot safety-related cables in raceways in violation of regulatory require-3ents. The NRC Technical Review Team (TRT) reviewed NRC Region IV (RIV)
I fiespection report 83-03 (November 8,1982) and found that the RIV investigation of the two cables specifically identified by the alleger
.- eg. '
adequately addressed this allegation. The RIV investigation determined
?-
that one cable nc longer performs a ' safety-related function, and the ether 4b cadle ha: :e:: i a
- a 6" and was re :.sd 're
- s -a:e.,ay.
Ti "
determine: that si-ilar-appearing ite ir..-he same area were not 1:l':ss, but were, in fact, acceptable methods o' repairing minor cable ja:Let damage. The TRT cc:icurs with the RIV determination but notes tha g
regulatory requirements discourage-the use of' splices in raceways, as stated in position 9 of Regulatory Guide (RG) 1.75, " Physical Incependence of Electric Systems." If splices are made, the resulting design should be justified by analysis. This area is further addressed under the TRT QA/0C Category 8, "As Built."
t The TRT examined the cable spreading rocm, identified two cables installed -
' fin raceway, which to the untrained eye could appear to have been splicec, and inspe: ed the-in their as-installed condition. The TRT aisc revie ed i
the as;11:able irstallat'on/ inspection re:crds. This inspection a-d review re.saled tFa there were cable ja:Let repairs and that thay,;e e pre;erly ' dent * #'er, repaired, and c::; te.ted in at:crcance with a:::a:ls procedure 1.
\\

Conclusions and Staff Positions: Based on the inspection of the cable installations for cable splices in cable trays, workmanship, cable tray SN"7 fill, added load on cable trays by ther=olag material, and review cf J:ertir.e-criteria. :-::edures. RIV f es:ection re: orts. '.sta'la:': '

The TRT found inspection reports that did not indicate that the required witnessing of splice installation was done. Examp1'es are as follows:
IR ET-1-0005393 IR ET-1-0005396-7 IR ET-1-0005394 IR ET-1-0006776

Accordingly, TUEC will assure that all QC inspection requiring witnessing for butt splices have been performed and properly documented; and verify C,
that all butt splices are properly identified en the appropriate drawings e

_ Phase 1 The Phase 1 objective is to verthy the existance of inspection reports
.\\
documenting witnessing of splice installation. This will be accomplished in two steps:
A.
A review will be made of all inspection reports (in-process, post-installation and final) for the cables in the twelve inspection j
reports reviewed by the TRT to determine if required documentation of
.ritnessing exists.

2.
Action Identified by NRC Accordingly. TUEC shall develop adequate installation / inspection procedures to assure that the viring splicing materials are qualified for the appropriate service conditions, and that splices are not located adjacent to each other.
===3.
Background===
It is our understanding that the issue is as follows:
A.
Adequate provisions are not included in the installation procedures to verify the operability of those circuits in which splices are used.
B.
Adequate provisions are not included in the installation procedures to assure the splices are staggered within the panel so as to preclude splices in the same panels from pressing against adjacent splices.
C.
Adequate requirements are not included in the installation procedures to assure the splices are qualified for appropriate service conditions.
In order to address these issues, the following should be considered:
A.
All cable work involving termination, de-termination or splicing is required to be tested or ratested in accordance with Startup Administrative Procedures (SAP)-6. " Control of WorkonStationComponentsAfterReleaseFromConstruction$
to TUCCO"; SAP-22 " Retest Control"; and ICP-EE8 " Control e

Consideration was given to the mild environment in which the splices were to be used. The construction of the splice and the method of installation of the splice is similar to terminal lugs used in the panels. In additien, the splices are used in low power applications as specified in the FSAR.
