SUBJECT:

COMANCHE PEAK STEAM ELECTRIC STATION (CPSES)

DOCKET N05. 50-445 AND 50-446 TRANSMITTAL 0F SUPPLEMENT 3 TO THE HUMAN FACTORS CONTROL ROOM DESIGN REVIEW FINAL REPORT REF.: See Attachment Gentlemen: ,

Reference 1 submitted the Human Factors Control Room Design Review Final Report for Comanche Peak. References 2 and 3, respectively, submitted i Supplements 1 and 2 to that report. Supplement 3 is enclosed.

The Comanche Peak Detailed Control Room Design Review (DCRDR) was under active review by the regulatory staff during the time these reports were submitted.

As a result of that ongoing review, the staff identified, in a series of NRC documents written in 1984 [4, 5, 6, 7], a number of items regarding the  ;

, Comanche Peak Unit 1 DCRDR for which additional information was required.

1 Supplement 3 addresses those items by providing:

(a) the status of human engineering deficiencies (HEDs) requiring correction, I (b) a review and update of the comparison of the function a and task analysis results with the control room inventory, (c) verification that the design improvements implemented 3 to correct HEDs accomplish the desired corrections and do not introduce new HEDs and, (d) a description of the ongoing program.

J As you have already been advised, the remaining environmental surveys must await modifications to the control room lighting and ceiling and the installation of carpet in the main control board area. Once these activities have been compbded, the environmental surveys will be performed and any HEDs that are ident fied will be assessed using the methodology of the ongoing Human factors Engineering (HFE) program. The results of these environmental surveys will be provided in an additional supplement prior to Unit 1 fuel load. ,

TXX-88633 September 15, 1988 1 Page 2 of 2 Exceot for the aspect identified above, Supplement 3 provides the additional information required by the NRC staff for licensing to proceed based on a full DCRDR.

The Unit 2 DCRDR involves a comparison with Unit 1 to assess design differences. The status of this activity is also reported in Suppleme.it 3.

An additional supplement providing the results of this comparison will be submitted prior to Unit 2 fuel load.

If you have any questions concerning the Comanche Peak DCRDR, we would be happy to meet with the appropriate members of your staff to provide a response.
