1.0 INTRODUCTION

l O l l

This report has been prepared in response to NUREG-0737 item I.D.1 and details the l means by which the Review and Assessment Phase of a Control Room Design Review (CRDR) was conducted for the North Anna Power Station, owned and operated by the Virginia Electric and Power Company. North Anna Power Station Units 1 and 2 share a common control room. The review and assessment process was conducted using NUREG-0700, NUREG-0801, Supplement 1 to NUREG-0737 as guidance.

l 1.1 CRDR Program Structure

)

The CRDR is being conducted in three phases as follows: {

1.1.1 Phase I - Project Planning The initial phase in this review involved preparation of a Control Room Design Review (CRDR) Program Plan which was submitted to the NRC on March 1,1984. The Program Plan was based on guidance contained in NUREGs-0700, -0801, and -0737 Supplement 1 (paragraph 5.2.a). The Program Plan addressed the following topics:

1. Review plan

2. Manegement and staffing

3. Documentation and document control

4. Review procedures

5. Assessment

6. Reporting

7. Implementation.

The organization and scheduling reflected in the Program Plan were selected to coincide with other Virginia Electric and Power Company Emergency Response Capabilities (ERC) initiatives (e.g., RG1.97, EOP upgrade, SPDS implementation, etc.). Unless otherwise indicated, the review process as described in this summainf report follows the approach presented in the Program Plan.

1.1.2 Phase II - Review and Assessment The second phase of the CRDR involved collection, reduction and analysis of data pertaining to the adequacy of the CR design from a human factors perspective, and assessment of any human engineering discrepancies (HEDs) identified during this process.

1

i The assessment procedure included:

1. A determination of the error potential, consequence of error and safety importance of each HED.

2. Identification of HED resolutions. l

3. Assurance that no additional HEDs are introduced as a result of these i resolutions. l The present report represents the conclusion of Phase II for North Anna Power Station. The report describes the methods, results and implications of the North Anna f CRDR.

l 1.1.3 Phase IB - Implementation  ;

The final phase in the CRDR will be to implement the corrective actions for the i HEDs. Following implementation, the HEDs will be re reviewed to ensure that the  !

corrective actions were complete and adequate and that no new HEDs have been j introduced. If, for some reason, a safety significant HED cannot be fully corrected, the (

cause and consequence of this condition will be documented. 1 I

1.2 Review and Assessment Figure 1-1 shows, in general, the task flow for the review and assessment phase of  ;

Control Room Design Review. A brief discussion of the activities conducted in the review I follows this figure. The Control Room Design Review was conducted using the NUREG- j 0700 guidelines. Planning, staffing, technical approach, and prioritization were conducted in accordance with the guidelines as stated in NUREG-0700.

The present Control Room Design Review report closely follows the outline recommended in Section 5.2 of NUREG-0700. Specifically, this final report discusses: ,

o The Control Room Design Review phases.

o A review of the results of human engineering discrepancy assessment.

O The results are organized into the following groups:

- operating experience review findings (documentation, etc.)

- survey findings (annunciator, communications, etc.)

- task analysis findings (panel /workspace) and verification of human factors engineering suitability and validation of functions findings (control room traffic, workload distribution, and man / machine functional allocations).

o Improvements to be made -

- enhancements / justification / extent of correction

- design alternative / justification / extent of correction.

I o Scope and scheduling of additional human engineering activities.

1.3 Review Procedures This section presents, in general terms, the review procedures employed. Detailed descriptions of the procedures employed and results'of each activity are presented in  ;

sections 2.0 - 4.0. Data collection, analysis and documentation were subdivided into five subtasks as follows:

o Review of Operating Experience o Assemble Control Room Documentation o Control Room Surveys o System Functions Review and Task Analysis (SFRTA) o Verify Task Performance Capability and Validation of Control Room Functions.

)

1.3.1 Review of Operating Experience This task was composed of two subtasks: 1) conduct of operator questionnaires and interviews, and 2) review of plant operational experience through Licensee Event Reports, Deviation Reports, and Engineering Work Requests. This review task was conducted in accordance with the guidelines of NUREG-0700.

1.3.2 Assembly of Control Room Documentation In this task, a control room data base was established to support subsequent evaluation. A library was established with control room related documentation (technical specifications, drawings, etc.), control room components were photo-documented, and a l half scale photomosaic mockup was constructed. The library and photo-documentation ,

were located to support the effort. In addition to the library and photographic  :

2 documentation, a control room inventory of components was developed, identifying for l N I 4

each component its location, system relationships, functions, and characteristics.

Included in the inventory was'all the information necessary to verify the availability of instruments required to meet the operator information and action needs identified in the SFRTA (see Sections 1.3.4 and 1.3.5).

1.3.3 Conduct Control Room Surveys Much of the detailed assessment of the control room was conducted through checklist surveys. Surveys required the collection of data using preconstructed checklists and interview forms, and the taking of direct measurements of control room parameters such as noise levels, light levels, etc. The survey criteria are presented in the appropriate survey sections (3.1 - 3.14). For each survey, in Sections 3.1 - 3.1.4 a summary of Human Engineering Discrepancies is included. The surveys conducted were:

o Workspace checklist evaluation of various control room character-istics, such as layout and arrangement of CR furnishings, CR accessibility, etc.

o Anthropometrics analysis of reach and visual access to control l room components given physical configuration cf boards, panels, l layout, etc. The data were subsequently compared to checklist item requirements.

o illumination measurements were taken under various conditions l (e.g., normal and emergency lighting) and compared to individual NUREG-0700 items. j o Noise - direct

• measurements of noise levels were taken and com-pared to individhal checklists items. l l

o Heating, ventilation, and air conditioning (HVAC) evaluation by  !

direct measurement of HVAC parameters and comparison to NUREG-  :

0700 criteria. i o Emergency Equipment - data were collected by walk-throughs, use  !

of emergency garments, and checklist application.

o Maintainability checklist and questionnaire data concerning i operator maintained components (trend recorders, bulbs, etc.).

I o Communications - checklist evaluation of communications systems.

o Annunciators - checklist evaluation of annunciator systems; direct  ;

measurement of annunciator fonts, signal intensities, etc.

- coding methods (color, shape, pattern, etc.)

standardization of abbreviations and acronyms

- consistency of control use

- consistency of display movement or indication o Computers checklist evaluation of computer systems.

1.3.4 System Functions Review and Task Analysis (SFRTA)

System functions and tasks were identified and evaluated in this task. A four step procedure was employed:

o Identification of systems and subsystems by review of plant documen-tation and NSSS operating guidelines, and discussions with plant operations staff o Identification of event sequences to undergo Task Analysis. These were identified using:

- NUREGs-0737, -0660, and -0700

- Westinghouse Owners' Group Emergency Response Guidelines, Revision 1 (WOG-ERGS, Rev.1) o Identification of system / subsystem functions through document review and operator comment o Identification and analysis of control room operational tasks.

Task Analysis data served as an input to the verification of task performance capability and validation of control room functions (see paragraph 1.3.5). The result / product of this task was the specification of operator action and information requirements for all tasks performed under emergency conditions which provide emergency response capabilities. l l

1.3.5 Verification of Task Performance Capability and Validation of CR Functions (V&V)

This evaluation task involved three subtasks: 1) verification of instrument / control availability, 2) verification of human engineering suitability, and 3) validation of CR j functions. The first, verification of availability, was conducted using the Task Analysis and control room inventory. In general, tasks associated with control room functions were examined in terms of appropriate instrumentation in the control room (i.e., task equipment demands vs. actual equipment present in the control room). When specified l information or control requirements were not met, HED reports were prepared, including a description of the problem and an estimate of the potential effect on operator perform-1 ance.

e - , ..-.w-,-- w, ww.,- -

s Estimations of nonprocedurally-bound operations (e.g., boration, etc.) were gene-rated via operator responses during the V&V process. Also task sequences required in selected event sequences were estimated as to frequency of occurrence in the event sequences. Comparing both frequency and requirements data to the inventory, identifica-tion was made of: 1) the absence (in the control room) of task required information or control,2) the estimated frequency with which the information or control is required, and

3) the conditions (events, procedures, etc.) under which the information or control is required.

The second subtask, verification of human engineering suitability, involved using identified functional groups, and checklists to evaluate human engineering suitability in terms of sequence of component use, control / display proximity, and so forth. NUREG-0700 guidelines served as the principal source document for evaluation criteria.

The final subtask, validation of CR functions, involved analysis of workload and distribution of workload for operators performing specific task and event sequences. Also overall control room traffic was analyzed. Where potential problems in operator  !

movement or workload were identified, walk-throughs were conducted at the North Anna. l simulator.

1.4 Documentation and Document Control Three types of documentation were addressed: 1) reference documentation,

2) process and Human Engineering Discrepancy documentation, and 3) Control Room Design Review output findings and reports. j l

1.4.1 Reference Documentation l A program library was established with reference documents to support the Detailed Control Room Design Review tasks. It contains:

o Licensee Event Reports o Deviation Reports o Engineering Work Requests o Technical specifications and system descriptions o Piping and Instrumentation Diagrams o Floor plans o Instrument lists o Panel drawings and photographs o Software descriptions 1

o Various Nuclear Regulatory Commission and industry documents l

bearing on control room design (i.e., NUREGs-0700 and -0660, IEEE j

specifications and standards, human factors engineering texts, etc.).

l As required, this documentation was referenced to support specific tasks within the control room evaluations.

1.4.2 Process Documentation Data collection and reduction methods were documented for reporting purposes.

The general flow of information management is presented in Figure 1-2. Task plans I served as the basic process documentation. All data collected during the review were maintained in individual task folders in the central project files at Essex. The completed task plans will be turned over to the Virginia Electric and Power Company.  !

1.4.3 Guideline Human Engineering Discrepancy Documentation Data files for each Human Engineering Discrepancy were generated. For each task d requiring a report, file space was reserved for that report. The following information was

, recorded for each Human Engineering Discrepancy (HED):

o NUREG-0700 guideline number o Human engineering discrepancy problem description o Human engineering discrepancy assessment  !

o Human Engineering Discrepancy locations (components which are discrepant from the NUREG-0700 guidelines) o Action to be taken on the Human Engineering Discrepancy.

Figure 1-3 presents the Human Engineering Discrepancy form used to document and i report findings. All HEDs were entered into and are maintained within an electronic data base management system. The electronic data base management system will be used for tracking purposes to ensure satisfactory completion of Phase III, Implementation of Corrective Actions.

i 1.5 Management and Staffing Project management and staffing were fully described in the CRDR program plan.

l As described in the program plan, the Virginia Electric and Power Company CRDR team I was established to include representatives from all disciplines necessary to ensure 8

optimum performance of the review team. As such, engineering, operations, human factors, and other needed disciplines were included on the team. The CRDR team was composed of up to 27 members,9 constituting the dedicated core team. The core group was supplemented on an as required basis by the remaining individuals. The structure of the CRDR team is shown in Figure 1-4. The structure of the team has not changed since the program plan was written. However, in mid-1985 the composition of the team did change somewhat. Most notably, Mr. J. S. Fisher and Mr. R. F. Anderson are now, respectively, the Site Operations Coordinators for Surry and North Anna Power Stations.

They are also responsible for EOP generation at their respective stations. Both Mr. Fisher and Mr. Anderson hold SRO licenses and collectively represent over 30 years of nuclear operations experience. In addition, Mr. T. J. Voss replaced Mr. David Eike as the Lead Human Factors Specialist for North Anna Power Station. Previously Mr. Voss had been involved in the data collection activities for the project and he does have more than 5 years of experience in the application of human factors engineering to the nuclear power industry.

An in progress audit of the North Anna CRDR was held in November 1984.

Concerning project staffing, the NRC audit team recommended that Virginia Electric and Power Company personnel be more directly involved in the conduct of the control room survey. As such, a sizable portion of the CR survey activities were conducted not only with the half scale photomosaic, but also in the North Anna control room with the North Anna Site Operations Coordinator in attendance. During on site activities, which involved all of the 14 CR survey areas (see Section 1.3.3), on shift operations personnel were frequently involved in explaining the manner in which systems and components function as well as responding to other issues and questions concerning checklist items.

1.6 Assessment and Disposition of HEDs The final activity in the review process was the assessment and recommended disposition of human engineering discrepancies. This activity was conducted in two parts.

First, each HED was assessed for its potential to induce operator errors, by considering the potential impact on human performance. Second, the effect of the error, especially in  ;

terms of plant safety, was estimated by determining which systems and/or plant functions would be affected. Once this assessment was completed, the recommended HED disposition was determiwd. Disposition included enhancements, design changes, and/or I more detailed studies to determine specific design solutions. A detailed description of the I HED assessment and disposition process is presented in Section 5.0 of this report.

2.0 OPERATING EXPERIENCE REVIEW )

1 pb The operating experience review consisted of two tasks: 1) conduct of operator questionnaires and interviews, and 2) review of documents related to plant operating experience. The methodology and results of these tasks are described in the following sections.

I 2.1 Operator Questionnaires and Interviews Questionnaires and interviews were conducted in accordance with NUREG-0700 as part of the Control Room Design Review (CRDR) performed at North Anna Power Station. The objective was to solicit comments and observations from control room operating personnel concerning selected aspects of the design and operation of the North Anna control room. The methodology and results of the questionnaires and interviews are described in the following sections.

2.1.1 Methodology Operator questionnaires and interviews are conducted as part of the operating experience review for a CRDR to identify and record any human engineering discrep-ancies (HEDs) that have been encountered during the operation of the plant. NUREG-0700 recommends that a range of operations personnel be interviewed, including opera-tions managers, shift supervisors, shift technical advisors, senior reactor operators, reactor operators, and auxiliary operators.

The approach recommended by NUREG-0700 follows the general format of the critical incident technique in which the respondent is asked to describe specific incidents ,

that demonstrate positive or negative aspects of the design and/or operation of the I control room. This approach allows the interviewer to focus on critical success, failure and near miss situations encountered in actual plant operation. These situations are then analyzed, from a human engineering perspective, to determine any causal or contributing ,

1 factors related to the design and/or operation of the control room. )

In the present study, the operator questionnaires and interviews were part of an integrated CRDR process that employs four separate data collection techniques: observa-tion, measurement, document review and operator questionnaires / interviews. Prior to initiation of the CRDR, each guideline in Chapter 6 of NUREG-0700 was systematically p reviewed to determine the most appropriate data collection technique (s).

1 Those guidelines selected for inclusion in the operator questionnaire and interview forms i were translated into the appropriate format and entered into the forms.

Questionnaires were administered to operations personnel at North Anna. In

- addition,43 interviews were conducted on an individual basis to preclude consensual bias and to maximize the interaction between interviewer and respondent.

Fourteen areas of concern were included in the questionnaire and interview forms.

These included the following:

(1) Controls (8) Ambient illumination (2) Displays (9) Communications l (3) Verification of task perform- (10) Emergency equipment j ance (11) Workspace (4) Labels and location aids (12) Computer system

(5) Annunciators (13) Anthropometries (6) Ambient noise (14) HVAC.

(7) Maintainability j Example questionnaire and interview forms are contained in Appendix A.

2.1.2 Questionnaire and Interview Results

, 2.1.2.1 Operator Demography - Twenty-five reactor operators, 9 shift supervisors and 9 others were interviewed at the North Anna Power Station. The mean years of operational experience at North Anna is 3.9. Approximately 40% of the operators have l

had experience in the U.S. Nuclear Navy program.

2.1.2.2 Analysis of Data and Findings - The operator responses for individual items were tabulated on summary sheets. Similar operator responses to related items were combined, allowing potential problems to be considered in a more integrated fashion.

I However, even singular operator responses were treated as potential problems, so that no serious problem would be omitted from consideration. Potential problems areas identified by operators were documented as Preliminary Human Engineering Discrepancies (PHEDs) j on HED forms (Figure 1-3). The PHEDs later underwent the formal HED review process I as described in Section 5.0.

The results of the questionnaires and interviews conducted at North Anna revealed >

111 PHEDs. Numbers for the individual HEDs are given by task plan in the tables i

contained in Section 3.0. In the tables these HEDs have an "1"(for interview) in the data l i

, 2.2 Documentation Review This section summarizes the results of the documentation review performed to  !

l' identify documented conditions in the North Anna Control Room that may cause human performance problems. This review consisted of three elements as follows:  ;

{

i 1. Review of the North Anna Power Station Licensee Event Reports (LERs) i with potential HED implications I

2. Review of Engineering Work Requests with potential HED implications.  ;

i 3. Review of INPO Significant Event Reports (SERs) associated with human

! error with potential generic HED implications. .

The methodology and results of these reviews are described briefly in the following paragraphs.

4 l 4 2.2.1 Methodology l l

The list of North Anna Power Station Licensee Event Reports (LERs) was reviewed, 4

and those which involved potential HED implications were selected for further review.

l These reports were then evaluated to determine the events leading to the problem and the j nature of the problem, and to identify potential HEDs associated with the problem.  ;

I Similarly, lists of North Anna Engineering Work Requests were reviewed and those with potential HED impilcations were selected for further review. These documents were also

! evaluated to determine the events leading to the problem and the nature of the problem, f

} and to identify potential HEDs associated with the problem. Any human engineering  !

l discrepancies identified during the review were documented on HED report forms for l later consideration by the HED Assessment Team. ,

,  ?

j Beyond the limits of North Anna specific documents, a review of INPO SERs was l done to identify those SERs with possible HEDs of a generic nature that may also apply to f

North Anna. These SERs were also evaluated to determine the events leading to the problem, the nature of the problem and to identify potential HEDs associated with the f j SER.

F I 2.2.2 Results i t  !

Table 2-2 provides a summary of the documentation review results. Each North j j Anna Power Station document (LER, etc.) with potential HED implications is listed along l with the associated Preliminary HED. In all, the documentation review yielded 25 PHEDs.

The PHEDs were later subjected to the formal review process described in Section 5.0. [

3.0 CONTROL ROOM SURVEY J

The methodology used to conduct the CR surveys at North Anna Power Station incorporated a mix of traditional procedures and methods tailored to the specific requirements of the plant. The four basic methods employed within each survey were measurements, observations, questionnaires / interviews, and documentation reviews.

Within each of these methods, specific procedures were used to enst?e a comprehensive data collection, data reduction, and analysis process. The procedures were organized into a set of standardized task plans.

The survey process was structured into a number of separate tasks, each task involving a specific set of related control room design features. For example, environ-mental factors were organized into lighting, noise, HVAC, and workspace surveys. This structural approach, coupled with the standardized task plans, allowed for maximum flexibility during data collection, data reduction, and analysis, and resulted in a standard, well organized self-documenting process.

All task plans followed the general format of:

1) Introduction (including the objectives)

2) Review Team Selection and Responsibilities

3) Criteria (from NUREG-0700, Section 6.0) i 4) Procedures

! 5) Equipment and Facility Requirements

6) Inputs and Data Forms

7) Outputs and Results

8) Figures and Tables

9) Procedure Exceptions

10) Appendices (as required).

In addition to this general format, the control room survey task plans incorporated a standardized set of appendices that ensured a consistent well-documented process for data collection, analyses, assessment, implementation and audits. The appendix structure employed was:

Appendix A (Criteria)- This is a compendium of all 0700, Section 6.0 criteria in 0700 paragraph number order that is relevant to that task plan. It was used to summarize the final results.

O 25

Appendix B (Data Forms)- This appendix is further divided into the following:

B1 Measurements Data Bl.1 Linear Measurements (scalar, force, torque, dimensional, air volume, temperature, humidity)

Bl.2 Sound Measurements (noise auditory signals, communi-cations systems auditory response characteristics)

Bl.3 Light Measurements (illumination levels, luminance characteristics, contrast ratios)

Bl.4 through Bl.n Others (as required)

B2 Questionnaires and Interviews B2.1 Operations B2.2 Engineering B2.3 Instrumentation and Calibration B2.4 Management and Administration B2.5 through B2.n Others (as required)

Appendix C: Criteria Matrix Appendix D: Task Plan Critique Prior to conducting the surveys, Appendices B2 (Questionnaires and Interviews) from the various task plans were assembled and used to conduct operator interviews (see Section 2.1 of this report). The results of the interviews were used to direct the focus of the survey effort. An overview of the methods and findings of the CR surveys are presented in the following sections.

3.1 Workspace Survey ',

This section documents the results of the workspace survey conducted in the main .

control room at the North Anna Power Station. This review was conducted in accordance with the requirements of NUREG-0700, as specified in the Virginia Electric and Power <

Company CRDR Program Plan.

1 3.1.1 Objectives s i I

The objectives of the workspace survey were to: \

i

a. Assess the degree to which the workspace layout in the control room conforms to the criteria in NUREG-0700.

b. Identify and document any features of the workspace design that do not I

conform to the criteria in NUREG-0700.

3.1.2 Scope

] The scope of the effort extends to the assessment of the workspace design in the main control room at the North Anna Power Station, using the applicable guidelines as i 3 stated in NUREG-0700. The topics evaluated include:

1, o Furniture and equipment layout  ;

o Document organization and storage o Supervisor access i o Nonessential personnel access ,

o Procedure availability at consoles o Desk dimensions  !

o Chair design o Unit integration and interference o Personal storage o Ambience and comfort.

i 3.1.3 Criteria The criteria applied in this survey, identified by NUREG-0700 paragraph number, are: paragraphs 6.1.1.3a through g; 6.1.14a through e; 6.1.1.6a and b; 6.1.1.7; 6.1.2.6;

! 6.1.2.7a through d; 6.1.2.8a through g; 6.1.3.la and b; 6.1.5.6a and b; and 6.1.5.7a through

3.1.4 Method l 3.1.4.1 Data Collection ,

j a. Data collected during the operator interviews were reviewed to identify 1

any potential problems with CR workspace.

b. Data were collected through direct observation of the control room work space using the checklist contained in the workspace task plan. As necessary, operators on shift at the time of the survey were queried concerning the suitability of the control room workspace.

3.1.4.2 Analysis - Data were analyzed according to the following procedure:

a. All deviations from the criteria were recorded on Human Engineering Discrepancy (HED) reports. Recorded information included the items involved, a description of the problem including the NUREG-0700 para-graph number of the criteria, and a recommended solution,

b. The data collection method was also recorded on the HED form. Where data from two or more sources were contradictory, resolution of the conflict was achieved through data review and discussions with cognizant J plant personnel, i c. Upon completion of all analyses, the criteria of the workspace task plan were annotated to indicate compliance or noncompliance with the criteria.

3.1.5 Findings The findings of the workspace survey are presented in Table 3-1 "Workspace Survey Findings and HEDs Geuerated." Overall,56 criteria were applied to the workspace design j in the North Anna control room. Of these, 2 (4%) were not applicable, 36 (64%) were in 1

! compliance, and 18 (32%) were not in compliance. A total of 20 HEDs were generated which document all of the 18 criteria that were not met. In general, those HEDs were related to viewing of controls and displays from the operator's desk, the facilitation of communications and access to equipment by furniture and equipment layout, the storage of reference documents and procedures, the location of and communication with the shift j supervisor's office, and provision for and communication with restroom and eating facilities near the control room.

Table 3-1 also includes the category assigned .to each HED during assessment meetings (see Section 5.0 for an explanation of assessment category). Note that the category "CPT" stands for complete and indicates that no further action needs to be taken on an HED.

! Discrepancy (HED) reports. Recorded information included the displays j

or controls involved, a description of the problem including the NUREG-i 0700 paragraph number of the criteria, and a recommended solution.

1

b. The data collection method was also recorded on the HED form. Where i

data from two or more sources were contradictory, resolution of the conflict was achieved through data review and discussions with cognizant

{

plant personnel.

c. Upon completion of all analyses, the criteria of the anthropometric task plan were annotated to indicate compliance or noncompliance with the criteria.

1.2.5 Findings The findings of the anthropometric survey are presented in Table 3-2 "Anthro-  ;

pometry Survey Findings and HEDs Generated." Overall,45 criteria were applied to the ll displays in the North Anna control room. Of these,14 (31%) were not applicable,22 (49%)

were in complier.ce, and 9 (20%) were not in compliance. A total of 33 HEDs were l

generated which document all of the 9 criteria which were not met. In general, those  !

HEDs address controls and displays that are located too high or too low on the vertical

) panels, controls that are not located more than three inches away from the edge of the l console, and controls that are located more than 25 inches from the front of the console.

j Table 3-2 also includes the category assigned to each HED during assessment j meetings (see Sectica 5.0 for an explanation of assessment category). Note that "CPT" j means complete and indicates that no further action needs to be taken on an HED.

6.1.2.2 STAND-UP CONSOLE DIMENSIONS

a. CONSOLE HEIGHT TO SEE OVER - M YES When it is necessary for a standing operator to see over the top, console height (with or without annunciator panels) should not exceed 58 inches.

b. CONTROL HEIGHT - (Exhibits 6.1-5 and 6.1-6)

(1) The highest control on a stand-up M NO 12 A03044 CPT console should be within the highest reach of the 5th percen-tile female without stretching or I using a stool, ladder, etc.

(2) The lowest controls on a stand-up I NO 10A03003  !!!-7 console should be within the I 10 A03018 !!!-9 lowest reach of the 95th percen- 1 10 A03019 !!!-9 tile male without bending or i 10 A03020 111- 9 stooping. I 10 A03021 11- 6 1 10A03022 111- 9

c. BENCHBO ARD SLOPE - The bench- il NO 12A03044 CPT board slope, in conjunction with its depth, should result in all controls being within the reach radius of the 5th per-centile female, as illustrated in Exhibit 6.1 - 6.

d. CONTROL DISTANCE FROM THE FRONT EDGE OF Tile CONSOLE (1) Controls should be set back a M NO 12A03045 CPT minimum of 3 inches from the front edge to protect against accidental ac tivation.

(2) No control should be more than 25 M NO 12A03044 CPT inches from the front edge of the l

console. This accommodates the maximum reach of the 5th per-centile female adult as illustrated in Exhibit 6.1-6.

e. DISPLAY POSITIONING - (Exhibit 6.1-7)

(1) DISPLAY HEIGHT AND ORIEN-TA'110N (a) All displays, including annun- M YES ciator tiles, should be mounted so that they are within the upper limit of the visual field (750 above the horizontal line of sight) of the 5th percentile female.

(b) In addition, all displays and M YES annunciators should be mounted so that the angle from the line of sight to the face plane is 450 or greater.

The 5th percentile female determines the upper limit.

O The 95th percentile male h determines the lower limit.

(2) HORIZONTAL DISPLACE- M YES MENT - The oblique angle from the line of sight to a display located to either side of the working position from which the display must be read should be at least 450 This includes annun-clator tiles, which should be read-able from the acknowledge button. (See Exhibit 6.1-8.)

f. LATERAL SPREAD OP CONTROLS M YES AND DISPLAYS - The operator should be able to perform task sequences at a given work station with minimum repositioning. The amount of operator movement required depends on the arrangement of controls and displays, not simply on the lateral dimensions of the segments of the control board. The maximum lateral spread of controls and displays at a single-operator work station should not exceed /2 inches.

g. FOOT ROOM - Enough foot room is D YES needed to allow the operator to get close to the board without leaning. A clearance of 4 inches vertically and 4 inches hori.tontally is recommended.

6.1.2.3 SIT-DOWN CONSOLE DIMENSIONS

a. CONSOLE HlHGHT TO SEE OVER (1) If the seated operator must see O YES over the console, the console height should be no more than approximately 27 inches above the seat to accommodate the 5th percentile adult female. Assum-ing seat height adjusted to 18 inches, max! mum console height should therefore be 45 inches above the floor.

(2) See-over console heights above 45 O YES V inches may be acceptable, for example, where the seated opera-tor need only monitor (not read) status lights and annunciators beyond the console,if they are at a suitable distance and height.

b. CONTROL HEIGHT - All controls on a N/A N/A sit-down console should be within the reach radius of the 5th percentile female. Measurements should be made using seated shoulder height with the shoulder in line with the leading edge of the benchboard. This is illustrated in Exhibit 6.1-9.

c. BENCHBOARD SLOPE - The bench- M YES i board slope, in conjunction with its depth, should be such that all controls are within the functional reach radius of the 5th percentile female (as illu-strated in Exhibit 6.1-9) and all displays and markings can be read.

d. CONTROL DISTANCE FROM THE PRONT EDGE OF THE CONSOLE (1) Controls should be set back a M YES minimum of 3 inches from the front edge to protect against accidental activation.

(2) Other controls may be mounted as M YES far back as 25 inches from the console edge. This distance accommodates the extended func-tional reach of the 5th percentile as defined.

e. DISPLAY POSITIONING (1) All displays, including annunciator M YES tiles, should be mounted so that they are within the upper limit of the visual field "50 above the horizontalline of sight - of the t

5th percentile female (see Exhibit 6.1 - 10).

(2) In addition, all displays should be M YES mounted so that the angle from the line of sight to the display face plane is 450 or greater (see Exhibit 6.1-10). The 5th percen-tile female determines the upper limit. (Practically, there is no lower limit for a plausible sit-down console design.)

f. LATERAL SPREAD OF CONTROLS D YES AND DISPLAYS - (Exhibit 6.1-11)

(1) For control and monitoring actions that must occur in sequence, all necessary controls and displays should be within the maximum extended reach and the viewing range of the seated operator from a single reference j point. I j

(2) For the situation described in D YES item 1, above, and sustained or precise control action, the opera-tor should be able to reach the controls without having to bend / stretch significantly,

g. LEG AND FOOT ROOM - Sufficient M YES leg and foot room should be provided to enable seated operators to avoid awk-ward and uncomfortable positions.

Exhibit 6.1-12 shows the dimensions involved and gives minimums and ranges necessary to accommodate the 5th to 95th percentiles (as defined in l Exhibit 6.1-5).

h. WRITING SPACE ON CONSOLES -

Writing space may be needed by opera-tors working at consoles.

(1) An area at least 16 inches deep N. A N/A (L / and 24 inches wide is recom-mended where these dimensions in the total configuration would fit operator reach espabilities. Less space may be adequate consider-ing the frequency and duration of writing requirements at control room consoles.

(2) If writing space is provided on the N/A N/A console itself, it should not inter-fere with viewing and manipula-tion of controls and displays.

(3) If writing is necessary but space N/A N/A on the console is not available, other arrangements such as a nearby desk or table should be provided.

3.3 Illumination Survey I

This section documents the results of the illumination survey conducted in the main control room at the North Anna Power Station. This review was conducted in accordance 1 with the requirements of NUREG-0700, as specified in the North Anna CRDR Program Plan.

3.3.1 Objectives The objectives of the illumination survey were tot

a. Assess the degree to which the illumination levels under normal and emergency lighting in the control room conform to the criteria in

, h UREG-0700.

b. Identify and document any charseteristics of control room lliumination that do not conform to the criteria in NUREG-0700.

I 3.3.2 Scope The scope of the effort extends to the assessment of the 111umination characteristics in the main control room at the North Anna Power Station, using the applicable guidelines as stated in NUREG-0700. The Illumination toples evaluated include:

o Illumination levels o Uniformity of illumination levels o Shadowing

] o Glare

! o Reflectance o Color.

i 3.3.3 Criterla i The criteria applied in this survey, identitled by NUREG-0700 paragraph number, are paragraphs 6.1.5.3a through h, and 6.1.5.4c.

The detalled definitions for the criteria are presented in Table 3-3.

i 3.3.4 Methods 3.3.4.1 Data Collection

a. Data collected during operator Interv!ews were reviewed to identify CR areas having potential lliumination problems. j O

50

- . = -

b. Direct measurements of CR lllumination were made using a Tektronix O- digital photometer (Model J16) with illuminance probe (Model J6511).

All equipment had been recently calibrated by Lessametric, Inc.

c. An illumination reading was taken at each control panel in the primary operating area as well as the computer consoles. See Figures 3-3A and 3-3B. Measurements were taken under normal lighting conditions.

Extant illumination levels were recorded on data sheets depleting the location at which the measurement was taken. All deviations from NUREG-0700 guidelines were noted and recorded.

3.3.4.2 Analysis - Data were analyzed according to the following procedures

a. All deviations from the criteria were recorded on Human Engineering Discrepancy (HED) reports. Recorded information included the lighting source or affected components, a description of the problem including the NUREG-0700 paragraph number of the criteria, and a recomtnended solution.

b. The data collection method was also recorded on the HED form. Where data from two or more sources were contradletory, resolution of the confilet was achieved through data review and discussions with cognizant plant personnel,

c. Upon completion of all analyses, the criteria of the illumination task plan were annotated to indicate compliance or noncompliance with the criteria.

O 3.3.4 Findings The findings of 111umination survey are presented in Table 3-3 " Illumination Survey Findings and HEDs Generated." Overall,11 criteria were applied to the displays in the North Anna control room. Of those criteria 5 (45%) were in compliance, and 6 (55%) were not in compliance. A total of 7 HEDs were generated which document all of the 6 criteria which were not met. In general, those HEDs address insufficient illumination levels in some areas, lack of uniformity in Illumination levels, shadowing, and glare in the control room.

Table 3-3 also includes the category assigned to each HED during assessment meetings (see Section 5.0 for an explanation of assessment category). Note that "CPT" means complete and Indicates that no further action needs to be taken on an HED.

a. INTELilGIBILITY AND COVERAGE -

(1) Intelligibility requires the inte- I NO 10000206 I-3 gration of carefully selected com-ponents (microphones, amplifiers, and loudspeakers) into an overall system providing good frequency response in the audio band which is critical for intelligibility. At a minimum, telephone quality is required (200 to 3300 Hz); higher intelligibility is achieved by a band of 200 to 6100 Hz.

(2) Coverage depends on loudspeaker O Y ES location. Adequate coverage requires that speakers should be placed so that they are available in all necessary areas and that there are no " dead spots" within any area.

p 3.9 Annunciator Survey b This section documents the results of the annunciator survey conducted in the main control room at the North Anna Power Station. This review was conducted in accordance with the requirements of NUREG-0700, as specified in the Virginia Electric and Power Company CRDR Program Plan.

3.9.1 Objectives The objectives of the annunciator survey were to:

a. Assess the degree to which the annunciator system in the control room conforms to the criteria in NUREG-0700.

b. Identify and document any features of the annunciator system that do not conform to the criteria in NUREG-0700.

3.9.2 Scope The scope of the effort extends to the assessment of the annunciator system design in the main control room at the North Anna Power Station, using the applicable guidelines as stated in NUREG-0700. The toples evaluated include:

p o General system design O o Alarm parameter selection o First out annunciators o Prioritization o Cleared alarms o Signal detection o Auditory coding o Visual annunciator panels o Visual alarm recognition and identification o Arrangement of alarm tiles o Tile legends o Tile readability o Annunciator controls o Annunciator response procedures.

3.9.3 Criteria The criteria applied in this survey, identified by NUREG-0700 paragraph number, are: paragraphs 6.3.1.1; 6.3.1.2a through d(2); 6.3.1.3a through d; 6.3.1.4a and b; 6.3.1.5a through b(3); 6.3.2.la through f; 6.3.3.la through b(2); 6.3.2.2a and b; 6.3.3.la through c(3);

I and 6.6.6.2a, b, and c.

4 The detailed definitions for the criteria are presented in Table 3-9.

3.9.4 Method  :

3.9.4.1 Data Collection

a. Data collected during the operator interviews were reviewed to identify any potential problems in the design or operation of the annunciator j system.

b. Data were collected using the checklists contained in the annunciator

task plan.

c. Data were collected primarily through measurement and dircet obser-vation of the annunciator system in the CR. As necessary, system documentation (e.g., P& ids, electrical drawings, annunciator response procedures) were reviewed to augment and corroborate observations and interviews. ,

i 3.9.4.2 Analysis - Data were analyzed according to the following procedure:

a. All deviations from the criteria were recorded on Human Engineering i Discrepancy (HED) reports. Recorded information included the compo-nents or system involved, a description of the problem including the 4

NUREG-0700 paragraph number of the criteria, and a recommended l

solution.

b. The data collection method was also recorded on the HED form. Where j data from two or more sources were contradictory, resolution of the

! conflict was achieved through data review and discussions with cognizant j plant personnel.

1

c. Upon completion of all analyses, the criteria of the annunciator task plan were annotated to indicate compliance or noncompliance with the criteria.

i

3.9.5 Findings j The findings of the annunciator survey are presented in Table 3-9 " Annunciator Survey Findings and HEDs Generated." Overall, 97 criteria were applied to the l annunciator system in the North Anna control room. Of these,11 (11%) were not l applicable,47 (49%) were in compliance, and 39 (40%) were not in compliance. A total of 40 HEDs were generated which document all the 39 criteria whleh were not met. In general, those HEDs address set points, multi-input annunciators, general alarms, reflash O

6.3.1.1 GENERAL SYSTEM DESIGN Annunciator warning systems are the primary I YES control room interface to immediately alert the operator to out-of-tolerance changes in plant condition. Annunciator warning sys-tems consist of three major subsystems: (a) an auditory alert subsystem, (b) a visual alarm subsystem, and (c) an operator response subsystem (see Exhibit 6.3-1).

Together, these three subsystems should be designed to provide a preferred operational sequence for annunciator warnings as indicated in Exhibit 6.3.2 6.3.1.2 ALARM PARAMETER SELECTION

a. SET POINTS 'Ihe limits or set points for initiating the annunciator warning system should be established to meet the following goals:

(1) Alarms should not occur so fre- I NO 10 A02903 I-4 quently as to be considered a Q nuisance by the operators.

(2) However, set points should be D NO 10A02262 11- 7 established to give operators i 10 A02904 II-6 adequate time to respond to the i 10A02908 II-6 warning condition before a serious 1 10A02909 11- 7 problem develops. I 10 A02910 II ~

D 10 A02914 II-7 D 10 A02915 I-3 D 10 A02916 !!-5

b. GENERAL ALARMS -

(1) Alarms that require the control I NO room operator to direct an auxil-lary operator to a given plant location for specific information should be avoided.

(2) If general alarms must be used i NO 10 A02904 II-6 they should only be used for con- 10A02908 11- 6 ditions that allow adequate time 10 A02909 11- 6 for auxiliary operator action and 10 A02910 11-7 subsequent control room operator action.

(3) A reflash capability should be O NO 10 A02107 11- 5 provided to allow subsequent alarms to activate the auditory p(j alert mechanism and reflash the visual tile even though the first alarm may not have been cleared.

d. MULTI-UNIT ALARMS -

(1) Alarms for any shared plant sys- N/A N/A tems should be duplicated in all control rooms.

(2) When an item of shared equip- N/A N/A ment is being operated from one control room a status display or signal should be provided in all other control rooms which could potentially control this equip-ment.

! The detailed definitions for the criteria are presented in Table 3-10.

} 3.10.4 Method l 3.10.4.1 Data Collection i

a. Data collected during operator interviews were reviewed to identify j; potential problems in the design, location, or operation of CR controls.

• l b. Data were collected using the checklists contained in the Controls Task Plan. The majority of the data were collected through interviews with CR operators and direct observation of controls in the CR. As i necessary, measurements were made of the physical characteristics

{ (e.g., size, separation, displacement of the controls). l 3.10.4.2 Analysis - Data were analyzed according to the following procedures

a. All deviations from the criteria were recorded on Human Engineering Discrepancy (HED) reports. Recorded information included the control 4 or controls involved (e.g., rotary controls, pushbuttons, J-Handle con-

, trols, etc.), a description of the problem including the NUREG-0700 l paragraph number of the criteria, and a recommended solution.  !

b. The data collection method was also recorded on the HED form. Where data from two or more sources were contradletory, resolution of the ,

confilet was achieved through data review and discussions with cognizant plant personnel.

c. Upon completion of all analyses, the criteria of the controls task plan

, were annotated to indicate compliance or noncompliance with the criteria, j 3.10.5 Findings {

j The findings of the controls survey are presented in Table 3-10 " Controls Survey Findings and HEDs Generated." Overall,150 criteria were applied to the controls in the j

North Anna control room. Of these, 34 (23%) were not applicable, 95 (63%) were in j compliance, and 21 (14%) were not in compliance. A total of 30 HEDs were generated ,

e. PRINCIPLES OF COLOR SELECTION (11 The primary principle which N/A N/A should be applied in selecting colors for coding purposes which do not have the immediate safety implications of red, green, and amber is to ensure that each color is recognized as different from any other. Exhibit 6.5-7 lists 22 colors of maximum contrast.

Each successive color has been selected so that it will contrast maximally with the color just preceding it and satisfactorily with earlier colors in the list.

The first 9 colors have been selected so as to yield satisfac-tory contrast for red-green-deficient as well as color-normal O

control room at the North Anna Power Station. This review was, conducted in accordance with the requirements of NUREG-0700, as speelfied in the Virginia Electric and Power Company CRDR Program Plan.

3.11.1 Objectives The objectives of the displays survey were to:

a. Assess the degree to which all displays in the control room conform to the criteria in NUREG-0700.

b. Identify and document any features of the displays that do not conform to the criteria in NUREG-0700.

3.11.2 Scope The scope of the effort extends to the assessment of the display design in the main control room at the North Anna Power Station, using the applicable guidelines as stated in

! NUREG-0700. The display topics evaluated include:

o Display failure o Usability of displayed values o Readability o Printing on the display face o Scale markings I o Coding o Display movement o Scale pointers o Zone markings

! o Light indicators (legend and simple) o Legend design o Trend recorders.

]

CRT displays were evaluated as part of the computer survey. Several NUREG-0700 guidelines appropriate to displays are addressed as part of task analysis and task verification and validation activities. These guidelines have been incorporated into the

verification and validation evaluation reports.

i O 129

+ 3.11.3 Criteria The criteria applied in this survey, identified by NUREG-0700 paragraph number, are: paragraphs 6.5.1.1f; 6.5.1.2d(1) through e; 6.5.1.3a through c(1) and d(1) through d(6);

6.5.1.4a(1) through f; 6.5.1.5a through e and e and f; 6.5.1.6a through c(2) and d(3) through e(3); 6.5.2.la through c; 6.5.2.2a(1) through c; 6.5.2.3a through c; 6.5.2.4a through c(3);

6.5.2.5c; 6.5.3.la(1) through c(1) and d; 6.5.3.2a(1), a(3), and b; 6.5.3.3a(1) through b(7);

6.5.4.la through d and g through k; 6.5.4.2a(1) through b(4); 6.5.5.la(1) through c(2);

6.5.5.2a(1) through c; and 6.5.3.3c.

The detailed definitions for the criteria are presented in Table 3-11.

3.11.4 Method 3.11.4.1 Data Collection

a. Data collected during the operator interviews were reviewed to identify potential problems with the design, location, or information content of the CR displays,

b. Data were collected using the checklists from the displays task plan.

Data were collected primarily through operator interviews and direct observation of displays in the CR. As necessary, measurements were made of the physical characteristics (e.g., character size, height-to-width ratios, etc.) of CR displays. Where guidelines refer to consistency with operating procedures (e.g., 6.5.1.4.e), existing procedures were reviewed.

c. Data were recorded on the appropriate forms.

3.11.4.2 Analysis - Data were analyzed according to the following procedure:

a. All deviations from the criteria were recorded on Human Engineering Discrepancy (HED) reports. Recorded information included the instru-ment or instruments involved (e.g., legend lights, meters, chart recorders, etc.), a description of the problem including the NUREG-0700 paragraph number of the criteria, and a recommended solution,

b. The data collection method was also recorded on the HED form. Where data from two or more sources were contradictory, resolution of the conflict was achieved through data review and discussions with cognizant plant personnel.

c. Upon completion of all analyses, the criteria of the displays task plan were annotated to indicate compliance or noncompliance with the criteria.

3.11.5 Findings The findings of the displays survey are presented in Table 3-11 " Displays Survey Findings and HEDs Generated." A total of 109 criteria were applied to the displays in the 130

l l

North Anna control room. Of these, 7 (G%) were not applicable, 63 (58%) were in l compliance, and 39 (36%) were not in compliance. A total of 66 HEDs were generated which document all of the 39 criteria which were not met. In general, those HEDs address display labeling, usability, readability, adequacy of information presentation and methods of information presentation.

Table 3-11 also includes the category assigned to each HED during assessment meetings. Note that "CPT" stands for complete and indicates that no further action needs to be taken on an HED.

3.12 Labels and Location Aids Survey w This section documents the results of the labels and location aids survey conducted in the main control room at the North Anna Power Station. This review was conducted in accordance with the requirements of NUREG-0700, as specified in the Virginia Electric and Power Company CRDR Program Plan.

3.12.1 Objectives The objectives of the labels and location aids survey were to:

a. Assess the degree to which all labels and location aids in the control room conform to the criteria in NUREG-0700.

b. Identify and document any features of the labels and location aids that do not conform to the criteria in NUREG-0700.

3.12.2 Scope i The scope of the effort extends to the assessment of the labels and location aids in the main control room at the North Anna Power Station, using the applicable guidelines as stated in NUREG-0700. The topics evaluated include:

o Labeling of annunciator panels.

o Color coding of labels .

p 3.12.3 Criteria d The criteria applied in this survey, identified by NUREG-0700 paragraph number,  ;

are: paragraphs 6.3.3.3c(3); 6.5.1.6a through e; 6.6.1.1, 6.6.1.2a and b; 6.6.2.la through f; 6.6.2.2a and b; 6.6.2.3a and b; 6.6.2.4a through d; 6.6.3.la through e; 6.6.3.5; 6.6.3.6, [

6.6.3.7a and b; 6.6.3.8a through c; 6.6.5.la through h; 6.6.5.2a and b; 6.6.6.2a through c;  ;

6.6.6.3; 6.6.6.4a and b; and 6.8.3.2d. l The detailed definitions for the criteria are presented in Table 3-12. l 3.12.4 Method 3.12.4.1 Data Collection ,

a. Data were collected using the checklists from the labels and location  !

aids task plan. Data were collected primarily through interviews with operators and direct observation of the CR labeling. As necessary, ,

measurements were made of the physical characteristics (e.g., character i size and separation, height-to width ratios, etc.) of the CR labels. For j those guidelines related to consistency with operating procedures (e.g.,

6.6.3.3.c), operating procedures were reviewed. l

b. Data were recorded on the appropriate data collection forms. l 3.12.4.2 Analysis - Data were analyzed according to the following procedure: f

a. All deviations from the criteria were recorded on Human Engineering i Discrepancy (HED) reports. Recorded information included the labels involved, a description of the problem including the NUREG-0700 '

paragraph number of the criteria, and a recommended solution. ,

b. The data collection method was also recorded on the HED form. Where  !

data from two or more sources were contradictory, resolution of the conflict was achieved through data review and discussions with cognizant plant personnel.

c. Upon completion of all analyses, the criteria of the labels task plan were r annotated to indicate compliance or noncompliance with the criteria. i

i 3.12.5 Findings The findings of the labels and location aids survey are presented in Table 3-12

" Labels Survey Findings and HEDs Generated." Overall,113 criteria were applied to the -

labels and location aids in the North Anna control room. Of these, 3 (3%) were not

! applicable, 50 (44%) were in compliance, and 60 (53%) were not in compliance. A total of I 74 HEDs were generated which document all of the 60 criteria which were not met. In I

general, those HEDs address label content, temporary labels, lack of a hierarchical

, labeling scheme, spatial orientation, word selection, symbol meaning, position labeling, {

color usage, nonstandard abbreviations, readability of labels, and lack of demarcation. ,

6.3.3.3 ARRANGEMENT OF VISUAL ALARM TILES

c. LABELING OF AXES (1) The vertical a'nd horizontal axes M YES of annunciator panels should be labeled with alphanumeries for ready coordinate designation of a particular visual tile.

(2) Coordinate designation is prefer- O YES red on the left and top sides of the annunciator panel.

(3) Letter height for coordinate M YES designation should be consistent with a subtended visual angle of at least 15 minutes as viewed from a central position within the primary operating area.

6.5.1.6 COLOR CODING

a. REDUNDANCY - In all applications of 1 YES color coding, color should provide redundant information. That is, the pertinent information should be available from some other cue in addition to color.

b. NUMBER OF COLORS (1) The number of colors used for I YES coding should be kept to the mini-mum needed for providing sufficient information.

(2) The number of colors used for O YES coding should not exceed 11.

c. MEANING OF COLORS (1) The meaning attached to a I YES ,

particular color should be 4 narrowly defined. j l

(2) Red, green, amber (yellow) should I YES be reserved for the following uses:

Red: unsafe, danger, im med-late operator action required, or an indication that a critical parameter is out of tolerance.

Green: safe, no operator action required, or an indi-cation that a parameter is within tolerance.

Amber (yellow): hazard (potentially unsafe), caution, attention required, or an indi-cation that a marginal value or parameter exists.

. d. CONSISTENCY OF MEANING (3) The meaning of a particular color O NO 12A01301 Il-7

,g should remain the same both O 12A01303 Il-7 within and among the various O 12A01304 11- 7 systems to which it is applied. O 12A01305 CPT

e. PRINCIPLES OF COLOR SELECTION (1) The primary principle which O YES should be applied in selecting colors for coding purposes which do not have the immediate safety implications of red, green, and amber is to ensure that each color is recognized as different from any other. Exhibit 6.5-7 lists 22 colors of maximum contrast.

Each successive color has been selected so that it will contrast maximally with the color just preceding it and satisfactorily with earlier colors in the list.

The first 9 colors have been selected so as to yield satisfactory contrast for red-green-deficient as well as color-normal observers. The remaining 13 colors are useful only for color-normal observers.

(2) Colors selected for coding should O YES contrast well with the background on which they appear.

(3) Ambient lighting in the area in O YES which color coding is used will influence the apparent color of the coded element (especially for surface colors). Each color selected for coding should be evaluated under all illumination conditions under which it is used.

c. Prepare for task verification and validation which would assess the suitability of the control room design in supporting task performance.

4.1.2 Approach To accomplish the above objectivas, Revision 1 of the Westinghouse Owners Group Emergency Response Guidelines (WOG-ERGS) and the four volume set of background documents were used. In accordance with the NRC-WOG meeting of 29 March 1984, the WOG-ERGS, Revision 1, are considered a validated data base which defines the generic d plant systems and functions (including the primary action /information requirements) and allocates the functions between the human and the machine.

The system function review and task analysis was performed in two major steps.

First, generic data were developed based on the ERGS and background documents (Rev 1).

Second, the data were made plant specific by reviewing the ERGS with operations personnel to determine the action and information requirements for operators to perform each step. Plant setpoint documents, Emergency Response Tracking documents and step sequence tracking documents developed by Virginia Electric and Power Company's Nuclear Operations Department (NOD) to track each ERG step to its associated procedure step were also used to develop the plant specific action and information requirements.

During verification, the actual North Anna Power Station instruments and controls that were used to perform these functions were identified. If the control and/or instrument did not conform to the requirements of the task analysis, a Human Engineering Discrepancy (HED) Report was prepared.

4.1.2.1 Procedure The task analysis procedure developed by Essex Corporation extracted generic operator action and information requirements from the Westinghouse Owners' Group l Emergency Response Guidelines and Background documents, converted the requirements i

to a plant specific level and documented the results for use in the verification process.

The following paragraphs briefly describe the procedural details.

l 4.1.2.2 Action-Information Requirements Details (AIRD)

AIRD forms (see Figure 4-1) were prepared by Essex Corporation for each step, caution statement, and note in Revision 1 of the Emergency Response Guidelines (ERGS) and all the Function Restoration Guidelines. Essex staff identified all behavioral elements for each task and listed each element in the AIRD Behavior Element Table. A behavioral element is defined by the various behavioral and physical properties of an action requirement or an information requirement. Review of the AIRD forms was conducted by North Anna Power Station operations personnel to modify instrument and I control requirements as necessary. Plant specific setpoints were added, and the gener!c task analysis was made plant specific.

4 4.1.2.3 Action-Information Requirements Summary (AIRS)

All behavioral elements of a given type, independent of the ERG, ERG step or task in which they appear were collected on the AIRS forms (see Figure 4-2). Then, based on the information entered onto the AIRS form, the action or information requirements for

, the given behavioral element were entered in the summary of requirements block on each AIRS form. This formed the basis for an instrument and control specification.

In service inspection valve response times were also listed in the requirements summary block for valves which are safety related by function. This was done to identify infrequently operated safety related valves that have an actual stroke time significantly different from operator expectations. Identifying these valves will alert the operator of unusual response times and therefore avoid the potential for confusion.

SAMPl.E AIRS FORM

o 4.2 Verification of Component Availability and Sultability The objectives of this effort were to identify availability (presence) and suitability of required instrumentation and controls in the control room to support performance of system functions.

The basic criteria were: (1) the control and display designs should match the task needs and operator capabilities, (2) frequently required or important instrumentation or controls should be located in the control room, and (3) infrequently used or unimportant controls and instrumentation should be excluded from the primary panel locations in the control room.

During the week of November 4,1985, verification of equipment availability was performed by one human factors specialist, one North Anna Operations Coordinator with SRO license, and an ex-SRO with four years of experience in human factors. This analysis was accomplished by comparing the action and information requirements on the AIRS forms to the control room inventory as shown on a half scale, color photomosaic of the North Anna Power Station control room.

During the verification exercises, the following component availability and suit-ability questions were asked of the operators:

o Is all the information you require present in the control to perform C the task (s)?

o Are all needed controls provided to perform the task (s)?

o Do the controls and displays provide the appropriate range of information/ control?

o Are the controls and displays adequate in terms of precision and response time?

All findings discrepant from NUREG-0700 guidelines were documented in the form of HED reports.

4.2.1 Verify Human Engineering Sultability The objective of this effort was to identify man machine interface problems that may affect task performance, but that may not be evident in component surveys.

There are five major design issues (1) component suitability, i.e., whether each required component provides the appropriate range, precision, scale units, and response time; (2) the grouping of components with respect to function, sequence, importance, and frequency of use criteria; (3) control and display integration to ensure that associated 206

controls and displays are not dispersed and that their designs are compatible; (4) compo-nent discrimination through enhancements such as demarcation and coding techniques; and (5) panellayouts for consistency of conventions across all panels / units.

Verification of human engineering suitability was performed (1) during the verifica-tion of component availability and suitability effort using the photomosaic at the Essex facility, and (2) during walk-through/ talk-throughs of event sequences at the North Anna simulator by North Anna Power Station operators and Essex human factors specialists during the week of November 12,1984.

The activities involved in verification of component suitability efforts using the photomosaic were described in Section 4.2. The objectives of the walk-through/ talk-throughs were twofold; first, to verify the completeness of the task analysis and, second, to review the human engineering suitability of the control room design.

During the walk-through, all tasks analyzed were observed and reviewed in terms of human engineering suitability. Over the course of one week, one shift supervisor, two control room operators, one shift technical advisor, two human factors specialists and one simulator instructor walked and talked through each of the operator allocated and analyzed tasks at the North Anna simulator. At the end of each task or group of related tasks, the participating operators were asked the following questions pertinent to task performance, o Does the CR design adequately support task performance?

o Does equipment layout adequately support task performance?

o Does equipment design adequately support task performance?

o Do you know of any errors which have occurred during performance of this (these) tasks?

In cases where suitability issues were identified, the issues were discussed and subsequently documented in the form of HEDs.

4.2.2 Verification of Task Performance Capabilities Criteria The criteria applied to this process, identified by NUREG-0700 paragraph number, are: paragraphs 6.1.1.la and b, 6.1.3.1d and e, 6.3.4.3a and b, 6.5.1.la through f, 6.5.1.2a through f, 6.5.1.5d through f, 6.9.12c, 6.9.3.2a through d.

The detailed definitions for the criteria are presented in Table 4-2.

4.2.3 Task Analysis / Verification Findings The findings of the Task Analysis / Verification effort are presented in Table 4-2

4.3 Validation of Control Room Functions y Whereas the control room surveys evaluated control room equipment largely on a component basis, the objective of the validation process was to examine the organization of the components and the extent to which they function as an integrated whole to support control room operations.

The method employed for the validation process was a real-time simulation of selected scenarios at the North Anna simulator which challenged all of the critical safety functions. A step by step walk-through took place immediately after each real-time simulation. The scenarios are described in Appendix C. This method facilitated observation of any conditions or features of the control room which hamper or impede the successful performance of a task.

The validation walk-throughs were manned by North Anna Power Station operating personnel. They included a shift supervisor, two control room operators, a shift technical advisor and a simulator instructor. Before the walk-throughs were conducted, a briefing was given which included an explanation of the purpose of the walk-throughs and examples of potential human factors problems.

The observer team consisted of three human factors specialists. One of the human factors specialists had an SRO license with twelve years nuclear power plant experience.

J During the validation process, a walk-through validation form was used, with HF observers concentrating on appropriateness of control room layout, component location, and workload (see Figures 4-3A,4-3B). In addition, questions were asked concerning workload, excessive task complexity, and time constraints in task performance. In all cases where issues were identified, the issue was discussed in detail and subsequently documented in the form of HEDs.

1 4.3.1 Validation of Control Room Functions Criteria The criteria applied to this validation, identified by NUREG-0700 paragraph number, are: paragraphs 6.1.1.2a and b, 6.1.3.la through c, 6.1.3.2a and b, 6.4.2.2f(2), 6.4.3.la, 6.8.1.la through c, 6.8.1.2, 6.8.1.3a and b, 6.8.2.la through c, 6.8.2.2b, 6.8.2.3a and b, 6.8.2.4a and b, 6.8.3.2a through c, 6.8.3.3, 6.9.1.la through c, 6.9.1.2a through c, 6.9.2.la and b,6.9.2.2a through e,6.9.2.3a and b, 6.9.3.la through c.

l VALIDATION OF CR FUNCTIONS

1. Familiarize operators with objective and method - emphasize that this is an evaluation of the control room: CR layout, control panel layout and operator workload.

We are not evaluating the EOPs.

2. Select the appropriate procedure from the attached list, and inst:uct the operators to conduct the procedure exactly as they would during an actual event, particularly with regard to allocation of function / responsibility.

3. Confer with the simulator instructor to set up the simulator to challenge the appropriate safety functions.

4. Fill out the upper portion of the data sheet: Event name of transient being simulated (e.g., SGTR, ATWS following loss of off site power); Malfunction No number of simulated event; Functions safety functions being challenged (e.g., RCS inventory, j containment integrity); ERG # number of EOP used (e.g., E-2, ECA-0.0).

5. Observe operators walking through event in real time. Record any problems with j CR layout, Panel layout, Workload on the data sheet. NOTE: . Do not be constrained by q

these categories, record any HF problem you observe.

6. When the real time walk-through is completed, have the operators walk-through the event again, one step at a time. Observe each operator decision action sequence,

~; ensuring that the necessary controls and displays are available, appropriately designed and appropriately located. Record any discrepancies.

! 7. Query the operators concerning the following CR characteristics:

1

a. Location of controls / displays.

b. Design of controls / displays,

c. Completeness of information/ control capability.

4

d. Workload.

j e. Communications.

f. CR layout.

g. Any other comments concerning the event.

Record all operator comments on the data sheet.

6.4.3.1 PUSHBUTTON DESIGN PRINCIPLES

a. POSITION - Pushbuttons in a row or matrix 0 YES Background

(

should be positioned in a logical order, or in shading by system an order related to the procedural sequence.

6.8.1.1 ASSIGNING PANEL CONTENTS Controls and displays should be placed within the control room at locations which promote efficient procedures, safe operation, and maximum opera-tor awareness of the current system condition.

There are three general methods for achieving this condition. They arer (a) grouping by task sequence, (b) grouping by system function, and (c) grouping by importance and frequency of use.

a. GROUPING BY TASK SEQUENCE - Con- O YES trols and displays should be assigned to work i stations so as to minimize operator move-

> ment. To the extent practical, this assign-

! ment should consider both normal and emer-I gency procedures, it should be practical to perform all frequently occurring routine tasks with a minimum of human movement from panel to panel.

b. GROUPING BY SYSTEM FUNCTION - O YES Within the constraints of grouping by task sequence, controls and displays should be assigned to panels in functionalgroups related to system str'ucture. This grouping should promote easy understanding of the relationship between controls and system, and should assist graphic or pictorial display or system relationships,

c. GROUPING BY IMPORTANCE AND N/A N/A FREQUENCY OF USE - Within the constraints of grouping by task sequence and by system function, controls and displays should be assigned to panels depending on their importance and frequer.cy of use.

Controls or displays which are neither important to plant safety not frequently used should be installed in secondary panel f

V locations.

6.8.1.2 EFFECTIVE PANEL LAYOUT The location of controls and displays within a M NO 12 A03201 CPT single panel should make the effective use of the viewing and manual manipulative areas. The allocation of panel positions should first ensure the integrity of arrangement or grouping by system function and task sequence. Within those constraints, consideration should be given to the following factors: (a) the frequency with which controls and displays are used;(b) the significance of controls and displays in terms of their possible use during an emergency;(c) the importance of controls and displays to overall system performance; and (d) speelal requirements in using a control device or display instruments, such as the need for accuracy, speed, application of force, or a particular type of movement.

6.8.1.3 ENHANCING RECOGNITION AND IDENTIFICATION

a. SPACING - Spacing consists of physically 0 YES separating groups of components on a panel with enough space between groups so that the boundaries of each group are obvious.

i Spacing between groups should be at least the width of a typical control or display in the group (see Exhibit 6.8-1).

6.8.2.2 LOGICAL ARRANGEMENT AND O YES LAYOUT

b. OTHER EXPECTATIONS - Where other O YES operator expectations can be identified, components should be arranged to match these expectations.

6.8.2.3 LAYOUT CONSISTENCY The location and arrangement of recurring functional groups and of individua1 components of those groups should be similar from panel to panel or within a panel.

a. REPEATED FUNCTIONS - The 1syout of O YES identical control or display sets should be consistent at all locations.

b. MIRROR-IMAGING - Layouts of repeated O NO 12 A01321 CPT functions should not be mirror-imaged.

223

TABLE 4-3 VALIDATION OF CONTROL ROOM FUNCTIONS Page 6 of 12 suietues # 8 6.8.2.4 STANDARDIZATION When a precedent has been established in the arrangement and location of controls and displays, that standard practice should be followed unless other crucial considerations necessitate a change.

a. PANEL TO PANEL STANDARDIZATION - O NO 12 A01302 CPT Standardization should be maintained where O 12 A01316 11- 6 similar functions or panels are located at O 12 A01320 11- 7 several work stations or units are located at several work stations or units and must be used by the same personnel,

b. SIMULATOR-TO-CONTROL ROOM O YES STANDARDIZATION - Standardization should be maintained where simulators or procedure trainers are used that simulate ,

the actual operational equipment.

6.8.3.2 STRINGS OR CLUSTERS OF SIMILAR COMPONENTS On occasion it may be necessary to have a large group of similar components arranged together in sj strings, matrices, or other clusters. Those human factors principles presented in Section 6.8.2, Layout Arrangement Factors, should not be compromised where large clusters of components are concerned. However, considerations such as search time, discriminability of components, and avoidance of selection errors will often make a string or matrix the preferred arrangement. The following criteria should apply:

a. ORIENTATION - Horizontal rows of O YES displays should be used rather than vertical columns (see Exhibit 6.8-4)

b. STRING LENGTH - Strings of small displays should not exceed about 20 inches O YES on the control board.

- 5.0 ASSESSMENT AND DISPOSITION OF HEDs NUREG-0700 defines a Human Engineering Discrepancy or HED as "a departure from some benchmark of system design suitability for the roles and capabilities of the human operator." Section 6 of NUREG-0700 contains these design benchmarks or guidelines. While it can be expected that the CRDR process will produce reports of Human Engineering Discrepancies, it does not follow that all discrepancies will neces-sarily degrade operator performance to the point that plant operation would be affected.

The objective of the assessment process was for the HED Assessment Team (HEDAT) to  ;

evaluate the relative significance of the HEDs produced during the review phase. During assessment, those HEDs that are unlikely to degrade performance were separated from those that may degrade performance.

5.1 Introduction to Assessment The first rtep in the assessment process was to determine if a Preliminary HED represented any departure from guidelines. If so, the assessment team considered potential for inducing error, consequences of induced error, and safety importance of the s/ HED. Then, during the disposition process, the assessment team selected the means by which the HED will be corrected or provided a justification for any discrepancy not fully corrected.

All HEDs, including Preliminary HEDs, were reviewed by a committee consisting of, as a minimum, one senior human factors specialist, one nuclear systems engineer, one I&C engineer, two operations specialists (one from North Anna Power Station, one from Surry Power Station) and one operations specialist with experience in the human factors aspects of plant operations.

The assessment methodology described below differs from that described in the Program Plan. The decision process itself, in terms of the issues addressed (i.e., potential for error, consequences of error, and safety importance), is the same. However, the methodology does represent an improvement in approach. While the methodology used was still more qualitative than quantitative, it was less subjective than the approach described in the Program Plan. In the approach used, three simple yes/no responses, followed by two ratings on numerical scales, were required. To further reduce the subjectivity of the process, criteria lists were provided for the numerical ratings.

231 1 1

5.2 The Assessment Process The assessment process entailed the following activities (see Figure 5-1, HED Priority Record):

o Determine if each Preliminary HED is, in fact, an HED o If so, determine if the error has been documented (No/Yes).

o If documented, determine if unsafe condition or tech. spec. violation resulted (No/Yes).

o If not documented, assess potential for error on a six point scale.

! o Assess if HED is of high safety importance (No/Yes).

o Assess the consequences of error occurrence on a six point scale.

o Based on the above, assign an HED category / priority (from I-1 to III-9).

The HED Priority Record (Figure 5-1) contains a section for assessment and a logic i

i diagram. The diagram shows how the assessment data were integrated to assign categories and priorities to HEDs.

I 5.2.1 Determine if a PHED is an HED As defined above, an HED is a departure from the human factors guidance contained O in NUREG-0700 or from other appropriate benchmarks of human factors design. As a first step in the assessment process, a determination was made as to whether or not a Preliminary HED did, in fact, represent such a departure. If, in the considered judgment of the assessment team, a Preliminary HED was determined to represent an actual deviation, the remaining steps in the assessment process were carried out. If not, the i

reason for ending consideration of the PHED was recorded and the PHED was retained in l the data files. Reasons why nondiscrepant items were occasionally documented as PHEDs include:

j o Misinterpretation of interview / questionnaire items by respondents o Plant issues that are out of scope of the CRDR (if appropriate, these i

were referred to other Virginia Electric and Power Company entitles) o Misinterpretation of operator responses by interviewers o Incomplete or ambiguous interview / questionnaire responses o Misunderstanding by HF reviewers of the way components or systems function o Issues that have been corrected during the period between data collection and assessment.

Before ending consideration of the PHED, efforts were made to ensure that the assessment team understood the issue involved. For example, this might have entailed checking an ambiguous interview response. If any disagreement between assessment team members could not be resolved at this step or on any of the following steps, the disagreement was noted on the HED record.

i P

5.2.2 Determine if Documented Error Given that no control syste'm can be designed to be operationally error-free, the  !

purpose of the assessment process was to estimate Human Engineering Discrepancy impact on hypothetical (unknown) baseline error rates of control room components; i.e.,

will additional errors be induced by discrepancies from the guidelines? Estimates of l Human Engineering Discrepancy impact on error occurrence were determined quali-i tatively. If the HED had previously resulted in a documented error, the potential for error was considered to be absolute. For an HED to be considered as having resulted in a documented error, the error had to be recorded on an LER, Shutdown and Trip Report, Station Deviation Report, Engineering Work Request, or on other plant documents such as

{

operations log sheets. If a document error had occurred, then " Documented Error?" was l circled "YES" on the HED Priority Record. ,

5.2.3 Determine if Unsafe Conditions or Tech. Spec. Violation l If the HED had resulted in a documented error as described above, a determination  !

was made as to whether or not the error involved an unsafe cendition or a violation of  !

technical specifications. The document review and the expertise of the operations and ,

I enginering members of the assessment team were relied upon for this determination. If the error had resulted in an unsafe condition, or if a violation of technical specifications had occurred, the appropriate "YES" was circled on the HED Priority Record.

5.2.4 Assess Potential for Error i If no documented error relateo to the HED had occurred, then as shown on the HED Priority Record, an assessment of error potential was generated on a six point scale based on the interaction of the discrepancy with the criteria given in Table 5-1, " Potential for j Error Assessment Criteria." A rating of "1" indicates that a low probability of induced errors is expected as a result of the Human Engineering Discrepancy, and "6" indicates a high probability of additional errors being induced.

t 234

TABLE 5-1 b POTENTIAL FOR ERROR ASSESSMENT CRITERIA The following criteria will be considered in assigning the Error Potential rating:

1. The nature of discrepancy, including the following factors:

(a) The impact of the discrepancy upon the operator's ability to perceive and discriminate input information. Considerations include:

- Whether required information is provided.

- The effect of the discrepancy upon the operator's ability to locate, read, and interpret displays of interest.

- The effect of the discrepancy upon the operator's ability to see and hear.

(b) The impact of the discrepancy upon the operator's ability to process information. Considerations include:

- The likelihood of exceeding the operator's information processing capability.

- The likelihood of causing confusion or distraction.

- Operator fatigue or discomfort which may be caused by the discrepancy.

- Additional processing steps or processing errors which may be introduced by the discrepancy.

(c) The effect of the discrepancy upon the operator's ability to perform required actions. Considerations include:

O(/ - Whether required controls are provided.

- The effect of the discrepancy upon the operator's ability to locate the control.

- The effect of the discrepancy upon the operator's ability to use the control.

2. Conditions of stress which may exist when associated tasks are performed.

3. The past occurrence of errors as a result of the discrepancy.

4. The degree and prevalence of the deviation.

5. The familiarity of the components and systems involved.

6. The frequency with which the associated components and systems are used.

O 5.2.5 Assess Safety Importance For all HEDs a determination was made as to whether or not the HED was of high safety importance. This was based upon the collective judgment of the HEDAT members ,

as to whether or not the affected component or components were part of a safety related system. Important considerations included in this determination were whether the component was qualified as REG 1.97 equipment, if the component was classified as 1E, or if the component is necessary for recovery from an accident. If the HED was determined to be of high safety importance, the appropriate "YES" was circled on the HED Priority Record.

5.2.6 Assess Consequences of Error Occurrence The effect of the hypothesized error on plant operations was assessed on a six point scale as shown on the HED Priority Record. The criteria for assessment of error consequence are shown in Table 5-2.

5.3 HED Category / Priority The logie diagram on the HED Priority Record shows how assessment determinations were integrated to assign a category and priority for each HED.

Category (I, II, or III) was assigned by determining if the HED involved a documented error or by rating the potential for error. That is, Category I Human Engineering Discrepancies are those which have been noted from documented operational errors or problems reported by operators. All Category I Human Engineering Discrepancies are deemed to increase error potential, but consequences must still be assigned to determine ultimate significance. Category II Human Engineering Discrepancies are those discrepan-cies noted during CR surveys, task analysis, and/or operator interviews, which have been determined to be of valid concern and may warrant corrective action, but for which no documented cases of operator error were found during the Review of Operating Experience, but which have an error potential greater than "3." CategoryIII Human Engineerirg Discrepancies are those discrepancies noted by CR surveys and/or operator performance interviews which have been determined to have little impact on operator performance, and for which no documented cases of operator error were found during the Review of Operating Experience.

Once an HED had been categorized, its priority (1 - 9) was assigned by O. determining, as described above:

o If the HED had resulted in an unsafe condition or tech. spec. violation o If the HED was of high safety importance o The seriousness of the consequences of error occurrence.

As shown on the HED Priority Record, priority varied from a value of 1 (most serious) to 9 (least serious). A category and a priority was assigned for each HED. The assessment status of an HED, therefore, varied from I-1 (most likely to degrade plant safety and operations) to III-9 (unrelated to plant safety and least I!kely to affect plant operations).
