SLNRC 81-51, June 26, 1981: Same subject

Dear Mr. Denton:

The referenced letter discussed a detailed human factors evaluation of the SNUPPS control room that had been performed. During a visit to the Callaway site on July 29-31, 1981 by NRC personnel from the Human Factors Engineering Branch, SNUPPS was requested to provide the resolution of each of the human engineering findings identified in the attachment to the referenced letter. The enclosed table provides the requested information.

Ver truly yours,

sectionalized such that ccntrols and indications are grouped i

functionally. R ese groupings are so obvious to trained per-smnel that additicn of labels would be redundant. Additicn-ally, these labels would add visual clutter, and retract fran other, more useful signs and labels.

D earcation Lines No acticn is demed necessary. Demarcation lines are easily applied and altered in the field. Operaticns personnel should experiment with demarcation lines, using Appendix F of the Essex report as a guideline. This should be done after the operations group (W.C. & Callaway) have taken custody of their Main Control Boards. Mimics provide scoe mount of dmarcation.

16 2

Labeling No action is deemed necessary. It is understood that, in any situation involving operator stress, operaticn of the DG is autcmatic. 'Ibe meters identified by Essex are primarily for use in testing (when the key instrument is the synchroscope) or well into an accident sequence. A light cn tne control panel indicates to the cperator it safety equignent is powered frm the mergency bus.
