SUMMARY
j 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) in response to human engineering observations generated as a result of the g ; following activities:
- a. The Emergency Operating Procedures (EOP) validation
- b. The disposition of HEDs that were not complete at the time of the initial HED Resolution Report
- c. The evaluation of Category E HEDs -
- d. Miscellaneous CRDR human factors work
- e. Dispositions where it was determined that revision, clarification, or additional information was necessary
- f. The SPDS Man in the Loop Validation The E0P validation was performed at the South Texas Project simulator, located in the training facility, during May 1986. This effort and the results are described in the EOP Validation Report.
Disposition of HEDs not complete at the time of the initial HED Resolution Report (dated April 15, 1985, as revised August 12, 1985) and evaluation of nearly all of the Category E HEDs have been performed.

R, . HousTou CONTROL ROOM IGHTINO DESIGN REVIEW POWER CO. HED RESOLUTION REPORT ADDENDUM 4 PREFACE The control room deugn review (CRDR) of the South Texas Project (STP) Electric Generating Station was started in September 1982. This re. view was performed by Torrey Pines Technology for Huuston Lighting & Pcwer Company 1 (HIAP) with Bechtel Energy Corporation (Bechtel) acting as agent. j l The program plan was presented to the NRC at the STP main control panel mock-up in October 1982. The 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 address mounting evolutionary engineering changes and correct discrepancies with the NUREG 0700 guideli6es. In November 1982, a decision was made by H14P to completely relayout six main control panels and upgrade the remaining four based on the design study. This redesign effort was required to accommodate design changes resulting from plant design evolution and Regulatory Guide 1.97 requirements and to correct'
. discrepancies with 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 ten panels, Torrey Pines Technology engineers reviewed the rework for correction of known discrepancies and compliance with good human factors principles. The redesign effort on the main control panels was completed in April 19B3, The NRC performed an in-progress audit in May 1983, after R ich the panel vendor was provided with firm layout drawings. 110028-1 viii STP56 12/01/89

PCWVER oO. i HED KESOLUTION REPORT .] ADDENDUM 4 I l The NRC audit comments required the addition of several special studies to those alresdy in progress,1.g. , demarcation and hierarchical labeling. The most significant addition, the evaluation of specified parameters, resulted in a net reduction of 51 panel meters. The 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 discrepancies were performed. The demarcation and hierarchical labeling studies resulted in continued upgrading of the mock up. The completion of the panel relayout allowed the design of the annunciator system consistent with the relocations of many systems and subsystems, and a O reduction of active windows from 1055 to 642. gj
'Following the completion of these major efforts, HL&P has continued tae CRDR program, including resolution of human engineering deficiencies identified, using Bechtel and Torrey Pines Technology as required.
The 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:
- 1. Program Plan - Defines the initial plan for performing the CRDR during the plant's construction phase.
- 2. Criteria Report - Provides the detailed guidelines and basis for the CRDR and describes the interface between the control room and plant systems. This report also includes review procedures, plant conventions, and human factors data developed during the CRDR that

1.0 INTRODUCTION
1.1 CENERAL COMMENTS l The initial Human Engineering Discrepancy Resolution Report was prepared to provide in one document a summary of the HEDs and their resolutions, as approved by the Project Review Team and Management Team involved in the CRDR of the South Texas Project. This addendum addresses the HEDs not complete at I the time of the initial HED Resolution Report and those developed as a result ~ of CRDR activities since that time. This addendum is prepared in a manner to I be consistent with the initial HED Resolution Report. ! 1~2 . OBJECTIVE l I 1 The purpose of this addendum is to provide a structured reporting method for summarizing.the-resolutions of HEDs not completely resolved in the initial HED . Resolution Report and HEDs developed subsequent to that report in the l (- continuing program to apply human factors principles to the design of the control room. i. 1.3 METHOD OF REPORTING RESOLUTIONS

NOTE DISPOSITION CPT-1 The Qualified Display Processing System (QDPS) is a . microprocessor based system designed to perform several safety-related functions, as follows:
- 1. Data acquisition, processing, and qualified display for l post-accident monitoring
- 2. Date acquisition, display, and analog control for safe shutdown to address separation / isolation concerns for a postulated control room / relay room fire 1 1

- 4. Safety grade control (and position indication, as required) of several safety related valves Design changes and resolutions to human engineering observations
- have been identified that involve modifications to the QDPS.
Because the QDPS is microprocessor based, these modifications involve z,oftware changes; these software changes require completion of a comprehensive verification and validation (V6V) effort. The schedule for these design changes is discussed in the Executive Summary Addenda, Section 5.0, Item 22. Discussions of each HED resolution are provided below. 1 11oo2s 1 2-3 STP57 12/01/89

" estimated", and to delete "c,c" from the cubiclo cooler representation on the display.
l HED 1027 Two minor inconsistencies (incorrect PORV label, incorrect
,g '
(Cat. C) abbreviation) will be corrected at a later date. HED 1041 QDPS displays.of tank levels which are Tech Spec parameters will (Cat. B) be revised to display the levels in gallons, rather than percent, A when the Tech Spec requirement is in gallons. This change will V allow direct comparison of the Tech Spec requirement and the , actual tank level. Information has been issued to the Operations l and Training Departments giving the conversion from percent to gallons for each tank, allowing use of QDPS to verify compliance with the Tech Spec. This information has been included in the operator requalification program. HED 1126 Operator action points on the QDPS CSF displays will be revised to Cat. C) be consistent with the modifjestions being made on the SPDS CSF 'j displays. These changes will result in all operator action points on the QDPS CSF displays hav4.ng arrows and dasheo lines, with numerical vclues corresponding to t'5e potus trees.
