SUMMARY

I ADDENDUM S PREFACE The control room design review (CRDR) of the South Texas Project (STP)

Electric Generating Station was started in September 1982. This review was performed by Torrey Pines Technology for Houston Lighting & Power Company (HIAP) with Bechtel Energy Corporation (Bechtel) acting as agent.

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 j

activities, and authorized a design study to address mounting evolutionary engineering changes and correct discrepancies with the NUREG 0700 guidelines.

In November 1982 a decision was made by HL&P 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 L

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 1983. The NRC performed an in-progress audit in May 1983 after which the panel vendor was provided with firm layout drawings.

EXECUTIVE

SUMMARY

ADDENDUM 5 The NRC audit comments required the addition of several special studies to those already in progress, e.g., demarcation and hisrarchical 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 thrcugh validation.

Likewise, a specially structured control room review and human factors review of the corrective measures for all t

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 reduction o'f active windows from 1055 to 642.

Following the completion of these major efforts, HLaP has continued the 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:

Program Plan - Defines the initial plan for performing the CRDR during the plant's construction phase.

SUMMARY

i ADDENDUM 5 could be added to enhance operator effectiveness. The initial phase of this task force, to identify and resolve nonconformances to the " black board" philosophy, has been completed. This design concept indicates that when no abnormal condition exists dating full power operation, the annunciator windows should be extin;uished, thus exhibiting a

• black board" to the operators.

6 Implementation of the resolutions is nearly complete on Unit 1; complete implementation on Unit 2 is targeted for the first refueling outage, 1

The computer displays are currently undergoing a thorough review to verify consistency with established CRDR criteria. This review encompasses various computer and display aspects, including technical correctness, effectiveness of display layout, use'of symbols, abbreviations and acronyms, and ths use of color.

Previously identified llEDs are also reviewed for applicability to each J

display and appropriate resolutions identified. Review of the Safety Parameter Display System displays has been completed; the recommendations are currently being evaluated for implementation.

The schedule for remaining CRDR activities is provided in Section 5.

2.0 METHODOLOGY AND RESULTS i

2.1 METHODOLOGY The methodology for the Category E evaluations and other planned CRDR activities varies from that used prior to January 1, 1986, since the tasks involve evaluations deferred from earlier phases in the CRDR and verification of appropriate resolution of previous HEDs.

To proceed with the " Planned Activities" remaining from January 1986 (identified in Section 5, Items 1 through 16) in an orderly fashion, each i

, ( }

activity or HED was tabulated separately and a reference / comment form provided for it.

This form is shown as Figure 2 1.

During the review process, each

' activity or HED reference / comment form was annotated regarding compliance using one of the following:

y I

o N/A - Not applicable o

Yes - In compliance o

No - Not in compliance 1

If the item is identified as not in compliance, a human engineering L

l observation (HEO) form is filled out for disposition of the observation.

L (See Figure 2-2.)

In some instances, the item is again deferred, since it can not be evaluated due to the current control room status.

In this case, no compliance status is O

(,j indicated;:the item identification and the reference / comment form are retained for later evaluation.

Additional comments and observati,ons are made by operators or by engineering personnel.

These observations are also documented on HE0 forms.

The HEOs generated are then submitted for project assessment.

2.2 RESULTS 1

The status of the remaining evaluations of the " Planned Activities" (Section 5, Itents 1 through 16 plus item 25 for the Auxiliary Shutdown Panel), is summarized on tablas as shown below:

Table 2 1 Contr'o1 Room Table 2 2 Auxiliary Shutdown Panel Room Note that these tables provide the status of evaluations for both Unit 1 and Unit 2.

(Previous addenda have addressed only the Unit I control room.)

1 The auxiliary shutdown panel and Unit 2 control room Category E evaluations began with the review of the original Category E deferred items to identify which items were appropriate for review at these locations.

Design and component similarities between the two control rooms and the auxiliary shutdown panels resulted in the Unit 1 control room review of many items being applicable to the ASP and the Unit 2 control room as well.

A total of 13 HEDs have been identified since September 1988 through the Category E deferred criterie evaluations. An additional six HEDs have been identified through operator or engineering observations. Table 2 3 shows the categorization of these HEDs, which are shown in more detail in the HED Resolution Report Addendum 4 (beginning with HED 1143).

SUMMARY

ADDENDUM 5 The remaining control room Category E deferred items are shown in Table 2 4 (Workspace), Table 2 5 (Communications), Table 2 6 (Visual Displays), and Table 2 7 (Computers).

In addition, there are nine deferred items in the Visual Displays criteria that were previously categorized and therefore not included as Catpgory E items (refer to Table 2 8).

The Unit 2 Category E deferred items evaluations were performed prior to fuel load, with remaining evaluations generally the same as those for Unit 1 (refer to Tables 2-4 through 2 7).

The remaining ASP Category E deferred items are shown in Table 2 9 (Workspace) Table 2-10 (Communications), Table 2 11 (Visual Displays), and Table 2 12 (Computers).

Figure 2 3 presents the HED assessment factor criteria and implementation commitments.

The schedule for the remaining work is addressed in Section 5.
