Madsen, Chief Reactor Projects Branch U.S. Nuclear Regulatory Commission Region IV 611 Ryan Plaza Drive, Suite 1000 Arlington, Texas 76011 KMLNRC 81-080 Ref: NRC Docket No. STN 50-482/Rpt. 81-05
Dear Mr. Madsen:
This letter is written in response to your letter of April 27, 1981, which transmitted Inspection Report STN 50-482/81-05. As requested the deviation is being addressed in three parts:
a) A description of steps that have been or will be taken to correct it; b)
A description of steps that have been or will be taken to prevent recurrence; and c)
The date all corrective actions or preventive measures were or will be completed.
Finding Paragraph 7.b.
The NRC inspector reviewed Bechtel Specification 10466-E-009 for the Class IE 4160 Switchgear during closecut of potential 50.55(e) item in paragraph 3.e of this report.
The NRC inspector found that Ap-pendix A of this specification specifies a different color coding for redundant separation groups than that specified in the Final Safety Analysis Report (FSAC.
The Wolf Creek FSAR section 7.1.2.3 identifies the color coding for the separation groups as follows:
Separation Group 1: Red Separation Group 2 : White Separation Group 3: Blue 8108040219 910706 PDR ADOCK 05000482 G

r Mr. G.L. Madsen KMLNRC 81-080 May 21, 1981 Separation Group 4: Yellow Nonsafe ty
- Black Section 7.1.2.3 further states, "Within the control panel, where more than one separation group is present, wiring is !.dentified by separa-tion group.
Section 8.3.1.3 states, "Within control panels where more than one separation group is present, wiring is identified by separation group designation.
Section 8.3.1.3 further states, "In cases where the majority.
. is primarily one separation group, standard color wire and/or sleeves for the majority separation group is used. The remaining wiring is identified, using the appropriate color."
Bechtel Specification 10466-E-009 Appendix 7, Revision 6, paragraph 5.2.2 states, " Wiring of the various separation groups within the switchgear shall be identified (color-coded) in accordance with the following:
Separation Group 1:
Red Separation Group 2: White Separation Group 3: Blue Separation Group 4: Green
Response
a)
The use of green sleeves to mark 10 conductors in cubicle NB0ll6 (only) was allowed by specificatioc 10466-E-009 so that separation group differences would be readily apparent.
The vendors use of yellow lugs on the predominant separation group prohibited the use of yellow sleeve markers to identify the minority Separation Group cables.
FSAR Section 8.3.1.3 states that "In cases where the majority of the wiring within a cabinet or panel is primarily one separation group, standard color wire and/or sleeves for the majority separation group is used. The remaining wiring is identified, using the appropriate color." ' In the case of cubicle NB0116 the appropriate color was green as called for in the equipment specifications. Yellow was inappropriate as it would not allow a readily discernible difference between separation group.
b)
An investigation has been made to see if there were other instances where exceptions to the standard cable coloring 1

KMLNRC 81-080 May 21, 1981-scheme were used in the SNUPPS design and none could be found.
The intent and meaning of the FSAR has been met, however, j
to avoid misinterpretation of the word " appropriate",
i paragraph 8.3.1.3 of the FSAR will be modified to read, l
"The remaining wiring is identified using the appropriate l
color as defined in applicable specifications or drawings."
This F.9AR revision was discussed in a meeting with the Power Systems Branch of the office of Nuclear Reactor l
Regulation on May 14, 1981.
c)
This change to the SNUPPS FSAR will be submitted by July 15, 1981.
