SUMMARY

I This addendum to the HED Resolution Report summarizes the results of the resolution of Category A, B, C and D Human Engineering Discrepancies (HEDs) approved by the Project and Management Review Teams in response to human engineering observations generated as a result of the following activities:

a. De Emergency Operating Procedures (EOP) validation.

I b. De disposition of HEDs which were not complete at the time of the

! initial HED Resolution Report.

c. %e disposition of Category E HEDs which could be evaluated at this time.

'I

! d. Miscellaneous CRDR human factors work.

I I e. Dispositions where it was determined that revision, clarification or additional information was necessary.

I The EOP validation was performed at the South Texas Project simulator, located in the training facilities, during May 1986. his effort and the results are described in the EOP Validation Report.

I Disposition of HEDs not complete at the time of the initial HED Resolution Report (dated April 15,1985, as revised August 12, 1985) and disposition of the majority of Category E HEDs were performed in December 1986. Various other remaining CRDR tasks, as shown in the Executive Summary and its addenda, were also completed during December 1986.

HED RESOLUTION REPORT ADDENDUM 1 I PREFACE I The control room design review (CRDR) of the South Texas Project (STP) Nuclear Generating Station was started in September 1982. his review is being performed by Torrey Pines Technology for Houston Lighting & Power Company (HL&P) with Bechtel Energy Corporation (Bechtel) acting as agent.

I The program plan was presented to the NRC at the STP mock-up in October 1982. He basic review work for operator experience review, system function and task analysis and

, control room survey was completed in October 1982. In November 1982 the management team put a hold on CRDR activities, and authorized a design study to correct mounting evolutionary engineering changes and discrepancies with the NUREG-0700 guidelines.

In November 1982, a decision was made by HL&P to completely relayout six panels and upgrade the four remaining main control room panels based on the design study. This redesign effort was required to accomodate design changes resulting from plant design evolution and Regulatory Guide 1.97 requirements and to correct discrepancies with l

l NUREG-0700. In December 1982 the management team selected one of five alternatives studied for design implementation.

The mock-up was revised considering the 441 identified HEDs and evolutionary engineering changes. As the Bechtel layout engineers advanced the layouts of the 10 panels, Torrey Pines Technology engineers reviewed the rework for correction of known discrepancies and compliance with good human factors principles. He redesign effort on the main control panels was completed in April 1983. He NRC performed an in-progress audit in May 1983, after which the panel vendor was provided with firm layout drawings.

The NRC audit comments required the addition of several special studies to those already in progress, i.e., demarcation and hierarchicallabeling. De most significant addition was the evaluation of specified parameters which resulted in a net reduction of 51 panel meters. De extensive relayout required a repeat of the System Function and Task Analysis with verification and walk-through/ talk-through validation. Likewise a specially structured control room review and human factors review of the corrective measures for all Category "A" and representative Category "B" diserepancies were performed. De demarcation and hierarchical labeling studies resulted in continued upgrading of the mock-up. He completion of the panel relayout allowed the design of the annunciator system consistent with the relocations of many systems and subsystems, and a reduction of active windows from 1055 to 642.

%e documentation for this program was necessarily extensive in view of its design development nature. Documentation describing the work performed during the CRDR is summarized below and in Figure P-1:

It addresses the HEDs not complete at the time of the initial HED Resolution Report and those developed as a result of activities since that time. %is addendum is prepared in a manner to be consistent with the initial HED Resolution Report.

1.2 OB JECTIVE The putpose of this report addendum is to provide a structured reporting method for

. summariz.ing the resolutions of HEDs not completely resolved in the HED Resolution Report and the HEDs developed in the continuing program to apply human factors principles to the design of the control room.

1.3 METHOD OF REPORTING RESOLUTIONS De Category A, B, C and D HEDs addressed by this addendum and resolutions are shown in Section 2.
