SUMMARY

I This report summarizes the results of the detailed Control Room Design Review (CRDR) of the South Texas Project Nuclear Power Generation Station and addresses NRC audit comments noted in the NRC letter to Mr. J.11. Goldberg dated October 31,1983 (Docket Nos. 50-498 and 499).

'lhis CRDR was initiated to address the NRC identifieo control room design problems following its investingations of the 'Ihree Mile Island accident; namely:

1.

Non-compliance of control facilities with human factors principles.

2.

Defleiencies in information and controls available to plant operators.

3.

Inacequate operating proceoures.

This program is based on an overall liL&P plan to integrate the following pertinent TMI action plan (NUREG-0660) andf NUREG-0737 Supplement I related activities.

1.

Implementation of a safety parameter display system (SPDS) 2.

Implementation of Regulatory Guide 1.97 instrumentation for minimizing risk to plant safety I

3.

Implementation of instrumentation to monitor critical parameters following an accident (post-accident monitors) i I

This review was performed by a multi-discipline consortium of specialists from Houston Lighting & Power Company, Bechtel Energy Corporation and Torrey Pines Technology.

This review was initiated in September 1982, and will be on-going until the Unit 1 Control Room becomes operational. He control room for Unit 2 is planned to be identical to Unit 1, which was reviewed. Any differences will be reviewed using human factors guidelines to assure the same quality as the Unit I control room.

(

Re program was conducted in compliance with NUREG-0700 as defined in the Program Plan submitted by IIL&P to the NRC on October 11, 1982. The principal working tools for

{

this program were the full scale mock up of the control room, Figure S-1, located in the Bechtel engineering office in Houston, Texas and the plant simulator located at the Gould Simulator facility, at Long Islano.

'lhe CRDR and design evolutions (TMI requirements) resulteo in major revisions of the l

(

panel layouts, cesign features, and a series of special studies to effect major control room design changes consistent with NUREG-0700 guidelines.

The program made extensive use of operations and training personnel in the data collection phase, panel relayout work, enhancement phase, particularly the major stuales (annunciator, demarcation and hierarchiallabeling), and in the final validation phases.

l The two meetings with the NRC, reviewing the Program Plan and the in-process aucit conducted at the mockup, were very useful in the overall conduct of the program and in particular to the many task efforts to resolve disrepencies that were of major concern.

The principal elements of the human factors program developed the following major discrepancies and recommmended actions:

1 1.

Major panel relayouts as a result of the system function and task analysis, control room survey, design evolutions and Reg.

Guide 1.97 implementation.

l 2.

Major mocifications of the annunciator design as a result of the control room survey and the annunciator study prograin.

3.

Addition of hierarchial labeling and extensive revision of incivicual nameplates.

l 4.

Changeover of many switches to effect continuity with plant design conventions.

5.

Removal of many panel devices from the prime panel locations by relocation on back panels or elimination altogether.

I 6.

A panel surface paint technique (color pads) to show the association of panel devices in a system or subsystem resulted from a demarcation study. 'Ihis study resulted in a change of the basic panel background color from seamist green to belge.

PREFACE Be 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 Torrey Pines Technology for Houston Lighting & Power Company (HL&P) with Bechtel Energy Corporation (Bechtel) acting as agent.

De program plan was presented to the NRC at the STP 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 cesign study to correct mounting evolutionary engineering changes and discrepancies with the NUREG 0700 guidelines.

In November 1982, a decision was made by HIAP to completely relayout six panels and upgrace the four remaining main control panels baseo on the design stucy. Bis redesign effort was required to accommodate design changes resulting from plant design evolution and Reg. 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 identifiec 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 factor principals. He 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.

He NRC audit comments required the addition of several special studies to those already in progress, i.e., demarcation, and hierarchial labeling. De most significant addition was the evaluation of specified parameters which resulteo in a net reduction of 51 panel meters. The extensive relayout required a repeat of the System Function and Task u

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" discrepencies were performed. The y

L demarcation and hierarchial labeling studies resulted in continued upgrading of the mock-up. The completion of the panel relayout allowed the redesign of the annunciator

(

system consistent with the relocations of many systems and subsystems, and a reduction.

of active windows from 1055 to 642.

1.2 CRDR PURPOSE AND OBJECTIVES The purpose of this CRDR is to identify and implement control room design improvements that offer high probability for meeting plant safety and availability objectives. The following are the objectives of the program:

1.

Determine that the control room provides the system status information, control capabilities, feedback, and analytical aids necessary for control room operators to effectively accomplish their functions, i

2.

Identify characteristics of the existing control room instrumentation, i

controls, and physical arrangements that may impact optimum operator performance.

3.

Analyze and evaluate potential problems as identified in this review.

4.

Define and put into effect a plan of action that applies additional human factors principles to enhance cperator effectiveness. Particular emphasis is placed on improvements affecting control room design and operator performance under abnormal or emergency conditions.

5.

Integrate the CRDR review with other areas of human factors inquiries identified in the NRC Task Action Plan (Generic Letter 82-33/NUREG-0737, Supplement 1).

1.3 PLANT DESCRIPTION The South Texas Project (STP) is currently under construction in south-central Matagorda County on a site 89 miles southwest of liouston, Texas (see Figure 1-2). 13echtel is the

(

architect / engineer and Ebasco is the constructor. De station will consist of two 1250-Mh(c)(nominal) units. Each unit is powered by a hestinghouse Electric Corporation

{

nuclear steam supply system consisting of a four-loop, pressurizeo water reactor and supporting auxiliary systems.

De basic power cor. version unit is also furnished by h estinghouse.

Each turbine-generator is an 1800 rpm tandem compound unit and is furnished with

[

.N$ POWER CD.

The management team gave consideration to the advantages and disadvantages of performing the CRDR prior to completion of operating procedures, training, and construction of the control room complex. The decision to proceed with the review was based on the advantage of identifying major departures from good human factors design, if any, of the control panels prior to completion of manufacture. This would minimize negative transfer and retraining problems. To facilitate this review, project management authorized the construction of a full scale, realistic mock-up and provided facilities for an extensive review by human factors ano systems specialists at the Bechtel-liouston engineering offices with the reviewers performing most phases of their tasks in the vicinity of the mock-up.

2.2 REVIEW l

The review phase was the investigative phase. 'Ihis effort was organized into specialty task groups per Figure 2-3. Specialized personnel were selected as required for each task group from IIL&P, Bechtel, and Torrey Pines Technology. Approximately 25 engineers and key operations personnel participated in the detailed reviews and evaluations of the g

task groups.

2.3.2 Operating Experience Review The operating experience review task team (OERT) reviewed pertinent operating experience documents and conducted a survey of control room operations personnel. In addition to typical human factors operator concerns, the OERT emphasized systems operability. It received valuable input for use by the other task groups, particularly the Systems Task Analysis Team (STAT). Specific attention was placed on those normal plant procedures that experienced operators identified as having the greatest potential for human factors engineering enhancements. 'Ihis information was used in the selection process for those events that were analyzed by the STAT.

E A special meeting was held to review the methodology used in the preparation of operating procedures. Sample procedures were reviewed and comments submitted to the operations department.

The OERT:

1.

Reviewed, with key operations and training personnel, the pertinent information on training, assigned duties, anticipated work scheduling, a walk through of a generic operating procedure which was completed for general oparator orientation prior to the OER, and the availability of the various classes of operations personnel 5.5/02234 2-6 3867h/0112W

The analysis of each event involved the following phases:

1.

System functional review 2.

Traffic flow analysis 3.

Spatial operational sequence analysis

[

The functional review identified the broad functions involved in each event. A flow

[

diagram, with decision-action points, documented this review. He traffic flow analysis required the identification of each device used in the sequence, whether required for monitoring or for actuation. Traffic-link diagrams were prepared, showing the operator travel paths between control boards for the event. The spatial operational sequence analysis traced the sequence of actions required at a given control position, and through diagrams, ioentifiec the patterns involved. Tracing the operating path in this manner identified improperly located devices.

2.3.3.1 Results

[

Panel 001,002 and 003

(

The traffic link diagrams for all selected events were considered, as a group, to determine the overall patterns of traffic. De most obvious problem was the number of repeated

{

trips necessary between the ESF panels in order to control any one ESF system. If these controls were arranged by system, with those used most often located on CP-001 and those used least on CP-003, then control would be much easier. Bis is especially true since any emergency requires the same set of early diagnostic activities to determine exactly which type of emergency occurred.

Another major potential problem was the controls for Auxiliary Feedwater, which were g

spread among the three ESF Panels and Panel 006. Pump and valve controls and flow 4

Indication were located on the ESF panels, but the flow regulators were on Panel 006.

I The ESF traffic link diagrams were also used to rank the systems by frequency of use ano at what sequential point in the procedure it was used. This information was used to decide which systems should be nearest the " center of action", and minimize operator travel. 'Ihe data indicated that liigh llead Safety injection (IlliSI) and Low 11ead Safety injection / Residual lieat Removal (LilSI/RilR) were most important with component 1

cooling water (CCW) and containment spray next, followed by the diesel generators. This layout results in a system-oriented arrangement, a

Panel 004 The sequence diagrams showed that the operator had to move arouno almost randomly during start-up and emergency procedures using the charging and letdown systems. The j

panel equipment for these events were not arranged according to the sequence defined by the procedures.

which should be integrated with their respective systems.

{

Panel 007 The controls for condenser steam dump were not grouped and the isolation (PORVs, MSIVs and Bypass) valves referred to above needed to be relocated to 006 with other SG devices. 'Ihe condenser steam dump system was not arranged by functional groups. The controls for sychronizing the generator should be relocated to panel 007 from 010 so that they are with the turbine controls.

2.3.3.2 SFTA Supplemental Review and Validation l

After the redesign of the main control board layout was completed, the SFTA was i

reviewed to verify that the observations had been corrected and no new ones introduced.

'Ihe operator task identification sheets for the six selected events were revised to show the new locations of devices, both within panels, and between panels. In some cases, devices had been removed or added, requiring the revision of the instrument detail section of these forms. 'lhe traffic link diagrams were then revised to reflect the movement of instruments from panel-to-panel. The spatial operational sequence diagrams were revised to reflect the relocation of subsystems and of instruments within a subsystem. The six sets of diagrams were then evaluated for efficiency of operator motion.

E

'Ihe new layout resulted in significant improvement in the functional arrangement of the control boards. Operator travel between boards was recuceo. 'lhe results of this review i

are presented in the SFTA Validation Iteport.

l 2.3.4 Control Room inventory The inventory of controls, instrumentation, displays, and other equipment on the control room man / machine interfaces was performed at the time of the construction of the STP control room mockup. 'lhe information source used was the control room equipment list.

Each item on the list was located on the mockup in accordance with the issued panel layout drawings. The equipment list is prepared on a panel-by-panel basis, categorized by equipment type, and is maintained as a data base for ease of updating, revising, and sorting.

and verification. Devices identified by the control room survey as not complying with the control room criteria, such as wrong switch types, were also entereo in the data base. A significant number of panel adoitions resaltea from Reg. Guide 1.97 requirements and design evolution. The decision to add two control boards, for llVAC and for recorders, resulted in the relocation of many panel devices.

After the redesign of the panels, each of the 45 Category A HEDs and a representative sample of the Category B HEDs were reexamined. The results indicated that the observations had been corrected and no new ones created. %ese are presented in the Control Room Survey Validation Report.

2.3.6 Verification of Control Room Function The verification task group verified the availability of instruments and equipment neeced to implement each task. 'Ihis verification was made by comparing the requirements identified by the SFTA to the Control Room Inventory List. An adequacy determination of operator-equipment interfaces for task accomplishment was made and the observations were recorded. Formatted information developea during the inventory ano system function task analysis activities was used.

2.3.7 Validation of Control Room Functions In conjunction with the SFTA update, and after the control boarcs were revised, the CRDR team performed a validation of the control room layout. This valication was performed by two separate operating crews using walk-through/ talk-through techniques, and procedures developed for two SOEs; i.e., steam generator tube rupture and startup.

These two sequences are included in those analyzed in the SFTA.

I Re two walk-through/ talk-through sessions were videotaped to allow examination of the operator responses using the new panel layouts. Each team of operators made specific I

recommendations for displays to be incluced in the Qualified Display Processing System (QDPS). These are detailed in the SF1 A Validation report. The suggestec graphic displays are tailored for the following specific operating evolutions:

The graphics display software for the QDPS has not been finalized, and these recommendations will be considered for inclusion in the set of displays finally agreed upon. The results of this validation are presented in the SFTA Validation Report.

2.3.8 Annunciator Review The annunciator review was conducted by the Annunciator Study Task Group (ASTG) in accordance with the Program Plan and the annunciator review guide. Twenty-six meetings were held with an average of seven attendees per meeting. The review included all alarms of the main plant annunciator, plant computer, ESF bypass and inoperable status system, and the operators' alarm cubicle in the basement of the turbine building.

~

The review was performed in two phases. In the preliminary phase, a review of design documents, including various EPRI and NRC studies pertaining to annunciator systems, was completed; criteria for the annunciator and computer systems were prepared; checklists for the evaluation of the design compared to the criteria were generated and performed; and preliminary recommendations made. These recommendations were recorded as observations and incluaed in the Control Room Survey Report.

(

Re decision to redesign the control board layout invalidated the location of many alarm windows, and the final phase of the review was conducted after the control board redesign

{

was complete. A study guide was prepared to control this effort. The group performed a functional integration of the identified annunciators, assigned priorities, and reviewed

[

each window for applicability, position, wording, and operator actions. Design documents were examined to determine possibilities for eliminating windows of little utility, and for combining those windows of similar operator response. The study resulted in: a reduction b

of main panel active tiles from 1055 tiles to 642, a reduction in the basic window box size f

from 96 tiles to 48 tiles, messages reconciled with a standard abbreviation list,

{

calculations to enhance visibility of engraving, elimination or redistribution of alarms not

)

essential to prime panel space and integration with the ESF status displays and computer displays. The detailed results are reported in the Annunciator Report.

2.3.9 Special Studies During the CRDR, several observations were made of discrepancies that affectea the

(

overe.ll control room. These items were assigned to small task groups for determination of the correct course of action to integrate corrections into the control room design. The

{

results of tuese studies are summarized below ano presented in the Special Stuales Report.

2.3.9.1 Anthropometry Study

[

An anthropometry study was performed to evaluate the control boaro profile. 'Ihis study l

[

concluded that the control board profile was acceptable with allowance for " extended reach" for operators from 20th percentile female to 95th percentile male.

2.3.9.2 Labeling Studj The control room survey identified labeling us a human factors observation. There was no apparent hierarchial labeling, the labels lacked consistent abbreviations, and some labels were unclear in meaning. A study group was assigned, and a study guide issued. The study guide is an appendix to the Criteria Report. He study guide includes label parameters, character height, label size, color, and a uniform label format. Ilierarchial labe" vere made to conform to the criteria established. %e abbreviations from the Criteria Report were used to prepare consistent messages. The mock-up was modified to incluce the review recommendations anc reviewed by appropriate operations personnel. This effort resulted in a listing from which the panel vendor is to prepare labels for the control panels. Extensive use was made of operator reviews of labeling techniques that resultea in immediate recognition of the labeling content. Af ter the initial labeling review, labeling refinements where made considering the results of the Demarcation Study.

I 2.3.9.3 Demarcation Study The control room design review noted that tiie original panel layout provided for minimal demarcation of systems. This lack of demarcation could have caused operator confusion and delay in responding in times of high stress due to celay in locating the oesired controls or displays.

A design guide was prepared to structure and document a demarcation scheme that was the result of both industry survey and a broad technical input, through a study team. %e guide was added to the Criteria Report as Appendix U.

We team prepared a set of criMria for demarcing the control boards. After studying various methods, a recommencation was made to use beige for a basic panel color, with a color pad technique used for highlighting and grouping controls (see figure 2-4).

2.3.9.4 Meter Scales

[

The control room survey reported observations conecrning meter scales, for examples wrong progressions (sheet number 331).* no zone markings (sheet number 006), too many, and confusing gradations (sheet numbers 359 ano 361), gracation dimensions (sheet number 475), and different type styles (sheet number 357).

[

A study was performed to quantify e.camples of correct gradations, and to provide samples of zone markings for application to the meters that are to be zoned. He results are included in the Special Studies Report.

{

• See Control Room Survey Report for details 2.3.9.5 Recorder Survey

[

The revision to the panellayout included the relocation, from the main control panels to a

[

new recorder panel, of approximately 50 recorders that were considered unnecessary to the operation of the plant, during either normal or emergency evolutions. Nineteen l

{

recorders were retained on the main control boards. During the NRC Auait of May 1983, concerns were raised relating to these recorders. There is no dual speed capability to allow the operator to scroll down the record and view the parameter value quickly. A survey was performed on the main control board recorders to determine if any were usec by the operator in normal plant evolutions. One set of four recorders are used for

[

indication, i.e., the RCP seal water flows on panel 004. The operator uses these to establish and monitor flows before starting a RCP. De remaining 15 recorders are used l

h for either trending or for historical recording. In none of these cases is there a need for the capability to review fast transient developments. However, fast transients may be displayed and examined on the Emergency Response Facilities (ERF) computer displays.

2.3.10 Effectiveness An NRC audit of the redesigned control room was conducted during the week of May 2, 1983. As a result of that audit the following post CRDR activities were performed:

2.3.10.1 Knurled Knob Position Indicator Problem A study was made to correct the problem of 71 switch handles obscuring switch position markings. Twelve of the switches were changed to lioneywell selector switches which do not have the problem. The remaining 59 switch handles will be replaced with lever handles as recommended by VanCott and Kinkace in "The Human Engineering Guice to Engineering Design".

2.3.10.2 Distinguishing Legend Pushbutton From Legeno Lights Problem A survey study was made to select a method of cistinguishing legeno pushbuttons from legend indicating lighta. 'Ihe "close corner octagon" was selected by a consensus of g

operations staff and engineering personnel 3

2.3.10.3 Lack of Defined Color Usage Conventions in Published Form A survey was made to determine the color conventions that were used in the STP control room design. 'Ihis information was organized and adoed to the Criteria Report as Appendix S.

2.3.10.4 Guidelines for Applying Human Factor Engineering Principles to Control Panel Design Changes These guidelines were produced in response to the concern, expressed by the NRC audit team, that all future design changes include human factors review. 'lhis structured material was added to the Criteria Report as Appendix T.

3.0 CRDR ASSESSMENT AND IMPLEMENTATION All observntions identified in this program were processeo accoroing to the assessment h

and implementation methodology presented in Figures 3-1 through 3-4.

The Design Review and Technical Task Team documented these observations and recommencations on

{

Checklist Observation forms (CLOS) (Figure 3-5) which were submitted to the Project Review Team for assessment.

[

The initial step by the Project Review 'Ieam was to accept or reject the formatteo information where, in the latter case, they returned the CLO to the Design Review ana Technical Task Team for further evaluation anc resubmittal. Acceptec CLOS were categorized according to the Assessment Factor Criteria as outlined in Selection of HEDs

(

to be Analyzed for Correction (Figure 3-2). De criteria chosen provicea for a simple, but effective, relationship between assessment factor and implementation requirements

{

commensurate with the significance of the observation. Bis approach greatly reduced the need to consider various levels of safety while still accomplishing the assessment objectives of NUREGs 0700 and 0801.

[

[

All observations assigned Categories A, B or C were identified as Human Engineering Discrepancies (HEDs) and were analyzed for correction (Figure 3-3).

Correction of Category D results are optional. De first step in this process was to icentify those HEDs

(

which can be corrected by enhancement. He remaining HEDs were analyzed to identify design improvement alternatives and to select solutions. In addition, some HEDs will be corrected through training. An integral part of this step was the reapplication of the control room review process, as appropriate, to ensure that:

[

1.

Other guidelines were not violateo 2.

Other corrections were not invalidatea h

rL 4.0 CRDR NRC IN-PROGRESS AUDIT REVIEW

4.1 BACKGROUND

llL&P requested an NRC in-progress audit of the STP CRDR in April 1983. The prime purpose for the audit was to receive NRC review comments of the redesigned main panel

(

layouts prior to issuing a release to manufacture panels 001 through 010. 'lhe audit was conducted from May 2 through May 6,1983 at the mock-up facility in Bechtel's Houston

{

engineering facilities. The NRC was assisted by its consultants from Lawrence Livermore

)

National Laboratory. Figure 4-1 shows many of the audit participants at the mock-up, f

The following was available at the mock-up to facilitate the audit:

1.

A full-size control room mock-up.

2.

A half-size color photo mosaic of the control room simulator.

3.

A scale model showing control room layout.

[

4.

Sample controls and displays.

5.

A full scale panel section showing demarcation and hierarchial labeling techniques being developed to assist control room operators.

FL llL&P also provided a number of documents by mail and at the audit site to support the E

in-progress audit. Finally, HL&P, Bechtel Energy Corporation, and Torrey Pines Technology (human factore consultant) personnel involvec in the CRDR were available on 7

a daily basis during the auoit.

The in-progress audit consisted of walk-throughs, document reviews, briefings, and discussions. Najor emphasis was placed on evaluation of the organization and process of the CRDR. CRDR results, particularly in areas which coula affect main control board layout, were also evaluateo.

m The results of this audit are reported in a letter from hnighton to Goloberg cateo October 31,1983 (Docket Nos.: 50-498 and 50-499).

I 4.2 AUDIT COMMENTS AND llL&P RESPONSES For clarity this section extracts the NRC comments from the audit results and puts them in quotes. The HL&P response follows the quotes.

4.2.1

Background

A Summary Report is to be submitteo at the end of the CRDR. As a minimum it shall:

"1.

Outline proposed control room changes."

This CRDR has resulted in the following significant changes that are reflected on the released panellayout drawings:

I o

The original train-orientea layout of the Engineereo bafety Features (EbF) panels (CP-001, 002, ana 003) was totally revised to a system-oriented layout. In this recesign effort auxiliary feeowater controls were moved to CP-006 as recommended by the Operating Experience Review and SFTA. This effort permitted the correction of indicators on CP-002 that were located too high for accurate viewing. The auxiliary feedwater controls were moved from CP-001, 002 and 003 to 006. Figure 4-2 shows the functional allocation of systems for the ESF panels.

4.2.5 NRC Audit Conclusions l

A.

"Several recommendations resulted from the NRC evaluation of the STP CRDR. They were:

1.

Keep the operating experience review current through document review and periodic updates of the operator survey."

l See above 4.2.3, Item 1 "2.

During ve.rification and validation, use the control room mock-up to assess, the integrated effect of the fullest range of design improvements possible (to include labeling ano demarcation)."

See above 4.2.3, item 2 "3.

Update the simulator as soon as possible ana use it for operator training and confirmation of the integrated effect of design improvements (verification ana validation of proceaures might also be done conveniently on an updated simulator)."

A plan to modify the simulator is currently in th9 development stage. Completion of the modification is targeted to support the scheduled operator training activities in the fall of 1985.

"4.

Continue to assure participation of an adequate mix of personnel (including operators and human factors professionals) throughout the development and evaluation of design improvements."

Description of the completed control room inventory anc its use."

l Figures 4-10, 4-11 and 4-12 show typical printout sheets from the computer-based main control panel equipment list. De initial layout of the mock-up was made from this type of listing. The CRDR resulted in extensive changes to both the make-up (layout of equipment) of each panel and the type of equipment on each panet Here were significant changes made to switch types, meters and recorders. This inventory is a basic Bechtel engineering document and is in a continuous process of change. Changes will undoubtedly be made during the installation and plant startup stages. The application of human factors considerations is provided for by the Criteria Document; specifically Appendix 1, which cefines a review methodology to incorporate human factors concerns. Figure 4-13 shows a typical switch development and wiring scheme which is referenced on the inventory sheet Figure 4-11 (see item no.

001S054). The inventory sheets were also used during the control room survey and in the verification of the equipment and equipment l

characteristics defined by the Task Analysis process.

"4.

Description of the completed verification process and results."

In the verification of task performance capabilities (NUREG 0700 Section 3.7) the verification of availability was performed by the task analysis specialists using the mock-up and completing the formated information shwn in Figure 4-14 (see SFTA Report and SFTA Validation Report)."

The verification of human engineering suitability was also performed by the task analysis specialists. The principal tool used to evaluate the practicality of the inventoried displays and controls was the spatial operational sequence stucy. Figure 4-15 is a typical diagram. We diagrams are contained in the SFTA and 5FTA Validaticn Reports. in addition, NUREG-0700 recommenos the use

(

of CRS check lists. This concept was implemented by the execution of the CRS panellayout and control aisplay integration check lists assisted by the human factors specialist after most of the task analysis work was completed. In this check list review emphasis was placed on the task application for the panel hardware.

HL&P also plans to supplement this effort with the results of the verification efforts associated with its production of Emergency Operating Procedures.

'Ihe STP Emergency Procedures are prepared with a system that involves the shift supervisor (SRO) to direct the actions of two licensed operators. The SRO is responsible for performing diagnostics as the procedures progress. This validation effort resulted in the f.ollow up study of 112 meters g

associated with the control and protection channels of 53 5

parameters. This study resulted in the recommendation to eliminate 61 meters while adding 10 meters primarily through the use of the Qualified Display Processing System (QDFS).

'Ihe validation also uncovered a few procedural problems and identified QPDS display needs. See the evaluation of specified parameters in the Special Studies Report, and the SFTA Validation Report.

o An Operating Experience Review (OER) Validation was conducted as suggested in the May 83 NRC audit meeting.

Essentially 33 percent of the operators who provideo the basic data for the OER report reviewed the redesigned main panel layout with a human factors specialist to determine 11 the concerns they had identified were corrected and to determine if the corrections generated any new problems or discrepancies. Figure 4-16 shows a few of the 82 concerns a

1 4.2.8 Appendix Part C 1.

"The following general concerns about HL&P's control room survey ano special studies were identified:

Deviations from Criteria Deviations from HL&P criteria were observec in the mock-up (e.g.,

J-hanoles instead of selector switches). It is not known whether the deviations were errors in the mock-up or intentional. Assurance that the final control room configuration will follow conventions developed during the DCRDR is necessary. Intentional deviations should be treated as uncorrected or partially correctec HEDs to be justified in the Summary Repo rt."

See Appendix C for a listing of all known deviations from HL&P criteria with justifications.

" Disposition of HEDs The final disposition of many HL&P observations (HEDs) is not known.

Included are those in Category "E" (items which could not be assessed using the mock-up or simulator) and those whose proposed corrections has g

not passeo thew gh the full review hierarchy."

" Workstation Design The bulk of the workstation design guidelines in NUREG-0700 are based on anthropometric data.

HL&P conducted a

comprehensive anthropometric survey in response to this item. The present main control boards do not accommodate the full range of functional reach (5th percentile female to 95th percentile male) used in developing

(

NUREG-0700 guidelines. HL&P has proposed rearrangement of controls on the boards to reduce the magnitude of the problem.

That rearrangement and use of extended functional reach (i.e., leaning over the l

control boards to operate controls) will allow the main control boards to accommodate 5th percentile male /20th percentile female and larger 1

operators. The proposed rearrangement is an acceptable resolution to the l

discrepancy provided HL&P acts to ensure:

1.

'lhat controls are operable by (not just accessible to) all control room operators, and that no inaovertent activation of controls would result from allowing operators to lean over the main control boara to operate controls. HL&P will demonstrate that the controls are accessible to all operators."

This will be demonstrated by a written procecure using operators that range from the 5th percentile male /20 percentile female and

(

larger operators.

{

4.

" Location Aids The use of color padding as a demarcation technique is being explored by HL&P. The purpose of location aid techniques (including color padding) is to facilitate rapid, reliable operator orientation and search on complex

(

panels. As a general observation, color padding appears to be most effective when a small number of colors are used (i.e., 2-3 including backgrouno). Use of a larger number tends to result in visual clutter and degradation rather than improvement of operator orientation and search.

l l

HnUSTON CONTROL ROOM TlNG gggggy ggyggy

.3 OWER CO.

Attempts to convey information by manipulating color pad size, shape, location, or interconnection may also result in overextension of the technique. Although color padding can be a useful technique for entering operator performance on complex panels, it should be carefully developeo and evaluated.

1 Other location aid techniques (e.g., labeling, demarcation lines, mimics) appear to be limited in a way similar to color padcing. On complex panels, integrated use of several techniques may result in the most effective location aids. Again, careful development and evaluation are needed.

Considerable effort has gone into relayout of the STP panels.

Development of labels and location aids should enhance orientation to and search of those panels. Given the advantage of a full-scale mock-up, operator evaluation of the label and location aid schemes integrated with other improvements would help to assure that enhancement."

H1AP has expended an extensive effort to perform an integrated demarcation and labeling study. These studies were conoucted by a special team using a systems engineer, a human factors specialist and g

senior level operators for review. The review incluced the use of full l

scale mock-up panel sections that were patch painted and hierarchially labeled. This effort was consistent with the above hRC guidance. See the Special Studies Report for details.

" General Panel Layout Considerations of factors such as structural bracing of the main control e

boards and electrical separation had not been completed at the time of the introgress audit. Care shoulo be taken to assure that any layout l

changes due to these factors (especially on heavily instrumented panels such as CP006) do not degrade the operator interface. In addition, the

(

impact of effective hierarchical labeling on layout should be considered (e.g., on CP006 and above the reactor coolant pump seal recorders)."

Main centrol panels CP-001 thru 010 have been completed and meet current seismic requirements. The final structural design did not affect h

the basic layout recommended in the CRDR process.

g HL&P emphasizes again that prior to and following the NRC audit extensive use was made of operators in the review of label and location aid developments. The continuation of such reviews is provided for in the Criteria Report, Appendix T.

An ext,ensive effort has been made to find pushbuttons that meet all regulatory and design criteria. Dere are no such pushbuttons available; consequently, the present J handled switches will be used but will be distinguishea in a unique way.

I 5.

"B401 6.4.3.3.a

'Ihere are several cases on panels where it is not possible to distinguish a status light from a control pushbutton. An example of this is the panel pushbuttons and legend status indicators on CP006."

g See special studies for the use of the octogon closed corner solution to this problem.

6.

"B201 6.5.1.1.b There are two "zero" positions on the same scale for the same variable inoication. No "Plus, Minus" inoications on meter face. This u

applies to E.H. 'Ibrbine Control, TV ano GV Tracking meters."

This is an error in the mock-up. 'Ihe actual equipment will be verified.

"B304 6.5.4.1.b Recorders have different scales and scale l

markings on the recorcer chart paper as

compared to the meter scaling portion."

[

HL&P will purchase paper with scale markings to match the recorder scales.

"bl02 6.8.2.4.a Panel-to-panel standardization is not followed for some groups of controls which appear on more than one panet Examples are:

i 1.

BYPASS AND INOPERABLE status test buttons on CP001 and CP002.

2.

Annunciator control buttons.

l

(

3.

Plasma cisplay control buttons."

{

The final control room layout has standarizea the panel-to-panel grouping of controls.

[

9.

"B103 6.8.3.1.b Annunciator controls and BYPASS AND INOPEItABLE status test buttons on CP002

[

are located near each other.

'Ihey are similar and the operator may inadvertently

{

operate one when the other is intended.

This item was resolved in the final panel layouts utilizing different test button arrangements and distinct demarcation.
