ECT POWER CO.
PREFACE The control room design review (CRDR) of the South Texas Project (STP) Nuclear Generating Station was started in September 1982. This review is being performed by f
Torrey Pines Technology for Houston Lighting & Power Company (HL&P) with Bechtel Energy Corporation (Bechtel) acting as agent.
B Prior to completion of the CRDR, a decision was made by HL&P to redesign six of the ten main control panels. This redesign effort was required to accommodate design changes resulting from plant design evolution and Reg. Guide 1.97 requirements. Human engineering discrepancies determined in the CRDR have been or are in the process of correction.
The CRDR is described in the Program Plan document. It contains a detailed description of the plans for the majors task elements. Due to the control room redesign effort, a modified approach was required to complete and document the CRDR program. The following changes have been made in the CRDR Program Plan:
A.
The documentation program described in the Program Plan was changed to allow reporting of results on the individual CRDR tasks.
B.
An Implementation Plan Report, was written to describe the background and reasons for the redesign effort. It outlines the approach to be used for implementing panel layout changes.
I C.
'Ihe tasks described in the Program Plan have been completed for the I
original design. The SFTA and the control room survey have been updated to validate any design revisions.

1.0 INTRODUCTION
I At the time of the May 1983 NRC audit of the new layout of the STP control room panels, the " Control Room Survey Report" was not yet completed. However, a compilation of all HEOs/HEDs was furnished to the NRC to facilitate their review.
At this audit, a plan was reviewed for validating that the corrective measures taken for f
category "A" and "B HEDs corrected the discrepancies and did not create new discrepancies. Category "A" HEDs are those HEDs that could have safety consequences
)
and are considered mandatory. Category "B" HEDs are those that could enhance availability and are high priority improvements. Houston Lighting & Power committed to review all Category "A" HEDs and five representative Category "B" HEDs from each of the NUREG 0700 Section 6 review topics. This validation report presents the results of that review.

All 90 selected HEDs were reviewed by a Human Factors Specialist, who compared each f
stated discrepancy on the half-scale mosaic with the revised panel layout, to validate that l
the discrepancy was resolved and that the corrective measure did not create any new problem. During this process the systems engineer was consulted as required. The results were recorded on a form.

1 Three Category A HEDs remain to be resolved. These are; sheet number 367 which addresses the color green Rototellite indicator lights which cannot be distinguished when lit; sheet number 726 which identifies the bypass and inoperable status light legends as being unreacable due to narrow stroke width and inadequate character separation and line spacing; and sheet number 727 which states that legend messages contain more than three lines of text.
The HED (sheet number 376) concerning the scaling on the paper for recorder XR 6008 has I
not been resolved. The HED (sheet number 6) concerning the lack of meter zone markings a
has been resolved through a recommended technique that will be applied on a case-by-case basis in the field. All other Category "B" HEDs have been resolved, and no new observations created.
I 3.2 CATEGORY "B" HEDs The following category "B" HEDs were reviewed by the process noted in section 2.1.
