4 HUMAN FACTORS SPECIAL STUDY OVERVIEW

1.0 INTRODUCTION

Toledo Edison is conducting a series of special studies as a major part of its program to close out the Davis-Besse Detailed Control Room Design Review (DCRDR). These special studies will resolve the Human Engineering Discrepancies (HEDs) identified during the data collection phase of the DCRDR, in an integrated manner.

There are a total of 11 special studies:

1. Annunciator Special Study

2. Computer Special Study 1

3. Controls Special Study

4. Displays Special Study

5. Lighting / Illumination Special Study

6. Labeling Special Study

7. Noise / Communication Special Study

8. Operations Special Study

9. Engineering Special Study

10. Steam and Feedwater Rupture Control System (SFRCS) Special Study

11. Post Accident Monitoring (PAM) Panel Special Study i Ten studies were identified in the DCRDR Summary Report submitted in l 3

June, 1984. It was originally planned to 4ddress PAM Panel HEDs in i

the Displays Special Study. However, since changes to these panels must be completed by the end of the 5th Refueling Outage, it was i decided to treat them separately. I Each study in some respects differs from the others because of the i types of HEDs it addresses. Individual study plans, with the excep- l 3

tion of SFRCS, are provided in Appendices A-J. The SFRCS study plan j was previously submitted and approved as noted in the Restart SER (NUREG-1177, page 3-62) .-

4 Post-Implementation Verification (PIV) of the human factors adequacy l of the installed change (s) is not included in the scope of the studies. PIV will be conducted in accordance with appropriate project closeout guidance once the change (s) is implemented.

'2.0 OBJECTIVES The objectives of the special studies are to:

Collect sufficient-information'to accurately describe each HED and to support decisions regarding its resolution.

' Group and analyze similar-HEDs to ensure consistency in resolution.

' Analyze the cumulative and interactive effects among and between related HEDs.

Ensure'that no new HEDs are introduced by the proposed corrective actions.

Develop final corrective action recommendations that will result in integrated overall improvement.

Define and document the rationale for any HED for which correc-tive action is not required.

3.0 METHODOLOGY Four primary tasks have been identified for each study. These are:

Task 1: Group and Investigate HED Concerns..

To ensure consistency in analysis and resolution, HEDs in each '

study will be grouped according to type of concern. Preliminary working groups are provided in the detailed description for each-study. HEDs will be investigated to' ensure that they are still valid and require further evaluation.

Task 2: Analyze Needs for Enhancement or Design Improvement.

The primary focus of this task is the determination of the operational implications of each HED at the component level.

These.will provide the basis for establishing the need for corrective action. Additionally, the cumulative and interactive effects will be considered by evaluating'the interaction with HEDs assigned to other studies.

Task 3: Determine Recommended Corrective Actions The appropriate enhancement, design change (s), administrative controls or other corrective actions will be identified. The i specific analysis performed will vary with the. nature of the problem addressed.

l

Task 4: Final Decision in Corrective Actions All recommendations will be reviewed by Operations and Engineer-ing as appropriate before they are finalized. The HED Review feam will determine the final disposition of each recommenda-tion. Toledo Edison will initiate necessary corrective action through established Davis-Besse processes.

Methodology for the Labeling Special Study differs as resolution of Labeling HED's will occur through Control Room panel relabeling.

This is addressed in Appendix F.

4.0 ASSIGNMENT OF HED'S TO STUDIES Each HED identified during the DCRDR data collection process has been assigned to a special study with the exception of KED's 1.7.011, 6.1.015, and 9.2.030. These three were corrected as identified in the Restart SER (NUREG-1177 Appendix D, page 16). HED 9.2.065 was also identified as corrected, however, since follow-up action is required it has been assigned to the Displays Special Study.

As a general rule, each HED is assigned to only one study to ensure clear responsibility for resolution. There are however, a number of HED's assigned to more than one. Most of these involve SFRCS and PAM components which are also covered in the Controls and Displays studies. Potential interactive effects will be considered.

The HED Assignment Matrix is attached to this overview (Table 1, pages 1-11).

5.0 WORKING DOCUMENTS AND FINAL PRODUCT The analysis steps for each working group will be documented and maintained as a part of the DCRDR records. This will ensure that sufficient information is captured for use in developing recommended resolutions and that documentation is available to demonstrate that analysis was systematically performed.

The final documentation will consist of approved recommendations in l finalized HED reports. The updated HED reports will reflect final dispositions and the method by which each recommendation will be implemented. HED reports will document the rationale when it is determined that corrective action is not required.

i 6.0 STAFFING 1

l Each study team will consist of at least one licensed operator and a i

human factors specialist. Typically each team will also include at I least one system and/or design engineer. One of the study team members will be designated Study Team Leader. Toledo Edison )

l personnel are supplemented with experienced personnel from Essex Corp., HPR and Bechtel.

l

4 t

.4 t . - .

l Each study team _ leader will coordinate the' study and ensure adequate

' documentation.- The licensed operator (s), engineer (s) and human factors specialist (s) will develop detailed information to further ,.

define the HEDs and develop recommendations for resolution. Each

will arrange Participation from other personnel within his/her discipline as required.

A ED Review Team will review and approve all recommendations. .As a .

minimum the ED Review Team will consist of a DCRDR Project Leader or his designated representative, a licensed operator, at least one 1 system or design engineer and a human factors specialist. The DCRDR l Project Leader will monitor study progress, assist in obtaining input from others and coordinate review and closure activities.

7.0 SCEDULE The Annunciator, Labeling, PAN and SFRCS studies are in progress.

The remaining studies will be initiated in phases. All studies will be completed before the end of the 5th refueling outage (currently i i

scheduled for March 1988).

l l In addition to specific ED implementation commitments, the following commitments apply to-the studies:

ANNUNCIATOR - Any changes to multiple input annunciators deemed i necessary by the study team and approved by the HED Review Team will be implemented during the 5th. refueling outage.

LABELING - All control room relabeling, demarcation and simick-ing will be implemented during the 5th refueling outage. *

PAN - Preliminary analysis of PAN panel concerns has identified possibility of redesigning panel layout. If deemed necessary by the Study Team and approved by the E D Review Team, PAN Panel modifications will be completed during the 5th refueling outage.

SFRCS - New panel layout will be implemented during the 5th refueling outage to improve the operator interface with the SFRCS and Auxiliary Feedwater Systems.

All other corrective actions will be implemented by the end of the 6th refueling outage unless adequate justification exists for later implementation. f i

APPENDIX A l ANNUNCIATOR SPECIAL STUDY PLAN Page 1 DAVIS-BESSE ANNUNCIATOR SPECIAL STUDY PLAN

1.0 INTRODUCTION

This study plan outlines the methodology for evaluating annunciator-related HEDs generated during the Davis-Besse DCRDR. It also out-lines the methodology for the development of appropriate resolutions for those HEDs. Since any multiple input annunciator changes must be implemented during the 5th refueling outage, schedule priority will be given to evaluating and developing recommendations for the Multi-Input Annunciator HEDs. These recommendations will be submit-ted to the HED Review Team for final disposition and initiation of corrective action processes before other parts of the study are completed.

2.0 GUIDELINES The human factors engineering guidelines used to define and evaluate potential improvements to the Control Room Annunciator System is drawn primarily from NUREG-0700, Section 6.3 and EPRI NP-3448. In addition, Davis-Besse USAR requirements for annunciators in the Control Room will be considered.

3.0 SCOPE The Annunicator Special Study includes analysis, evaluation, and review, to develop recommendations for effective resolution of related HEDs in the context of the overall configuration of the Control Room Annunciator System. The specific F3Ds addressed in this study are listed in Exhibit 1. The list includes all annunciator HEDs which have not been fully resolved (corrected or justified),

except for those HEDs which can be addressed more effectively in the SFRCS or the Communications / Noise Special Studies.

Implementation of HED dispositions is not within the scope of the special study.

4.0 METHODOLOGY 4.1 Task 1 - Group and Investigate HED Concerns To ensure consistency in the analysis and resolution of Annunciator HED concerns, the HEDs addressed in this study are divided into the following working groups. These may be modified as the study develops.

1. Multiple Input Annunciators

APPENDIX A ANNUNCIATOR SPECIAL STUDY PLAN Page 2

2. Nuisance Alarms *

3. Need for Additional Annunciators

4. Layout and Visual Priority Coding of. Annunciator Windows

5. Annunciator Panel and Window Legend Labeling

6. Visual and Auditory Alert System

7. Annunciator controls

8. Maintenance and administrative requirements Exhibit 2 lists the HEDs by working group.

~

The HEDs in each group will be analyzed to determine overlaps

. and define any groupings that may facilitate integrated treat-ment of specific concerns.

Each group will be investigated by means of annunciator or control panel review, documentation review, discussion with Operations, Engineering and Maintenance personnel and additional evaluations or tests, as appropriate. The objectives of this investigation are:

To define HED problem descriptions in greater detail as necessary to fully understand and document the issues.

To identify any components which should be added to the list of components previously identified in an HED.

To identify and review any completed or initiated actions which may fully or partially correct an HED or may affect the analysis in some other way.

l

To ensure that any changes to alarms in resolving.KEDs are consistent with requirements for alarms in the USAR.

I 4.2 Task 2 - Analyze Needs for Enhancement or Design Improvement I The operational implications of the concerns identified in the HEDs will be determined. These will provide the basis for recommendations as to whether corrective action is necessary or desirable. Cumulative and interactive effects as factors in the significance of individual concerns will also be considered.

In August 1986, Toledo Edison started an ongoing program to identify, evaluate, and correct nuisance alarms. This program is defined in Nuclear Engineering Instruction NEI-321.1. The analysis of nuisance I alarms in this study will be conducted in the framework of the NEI-321.1 l results.

APPENDIX A ANNUNCIATOR SPECIAL STUDY PLAN Page 3 Analysis steps, to evaluate the operational significance of HED concerns and the need for changes to resolve the concerns, are-summarized below for each working category of HEDs.

1. Multiple Input Annunciators The following steps will be performed to evaluate the acceptability of multiple input annunciators:

a. Review the assessment justifications prepared before restart for HED 3.1.037, as stated in the Restart SER, Appendix D.

b. Determine and document the location of information 4 sources to clarify the alarm condition (e.g., Control Room panel, computer, local panel, the equipment itself).

c. Check and document the availability of suitable data from the alarm printer for each multiple input annunciator.

d. Evaluate need to provide separate annunciators for individual alarm conditions.

4

2. Naisance Alarms This analysis will reexamine the list of nuisance alarms with the plant at or near full power, and e' valuate the status of corrections that were previously' recommended.

Recommendations for follow-up and further corrective actions will then be identified.

The following steps will be performed to evaluate nuisance l alarms:

i

a. Conduct an additional nuisance alarm review per NEI-321.1 when the plant is at or near full power.

b. Compare the findings from the NEI-321.1 power alarm review with the list of alarms from the applicable HEDs and consolidate. Note corrected alarms, continuing cases, and newly identified alarms. Group alarms according to the apparent type of problem. -

Note any cases in which USAR requirements apply.

c. Review status of corrective actions that were recommended / initiated under previous NEI-321.1 re-views, but have not been completed.

d. Review the consolidated alarm list.with Operations to determine which alarms may be recommended for correc-

~

, tion or deletion.

Existing Alarms Operations and Engineering input is crucial for this analysis. The following factors will be considered in evaluating the need for additional annunciators and the potential for removing or combining existing alarms:

a. USAR Requirements

b. Relationship to procedure requirements, especially EP requirements. -

c. Significance to safety or plant availability of the alarm parameter or condition.

d. Availability of information from other sources.

e. Plant systems review guidelines as described in EPRI NP-3448.

f. Results of Task Analysis.

4. Layout and Priority Coding of Annunciator Windows The results of recent alarm system testing by EPRI will be considered to provide guidance for alarm system modifica-tions. Improvements will be recommended based on space constraints, engineering requirements, and cost.

5. Annunciator Panel labeling and Window Legends Panel labeling and window legends will be upgraded and brought into conformance with the applicable specifications developed in the Labeling Special Study.

6. Visual and Auditory Alert System The analysis of needs for corrective action to improve the visual and auditory alert system will be coordinated with the analysis of annunciator controls as described in Section 4.2.7. The analysis will include the following steps

a. Compare existing system functions to generically recommended functions.

b. With Operations, evaluate effects of differences

.between the Davis-Besse system and_the generally recommended capabilities. Identify examples of any operational difficulties that can be' introduced by the current system design.

APPENDIX A ANNUNCIATOR SPECIAL STUDY PLAN Page 5 i

c. With Operations,-evaluate auditory signal coding

, issues and determine operator preferences.

7. Annunciator Controls This analysis will.be~ integrated with.the analysis of the visual.and auditory alert system in Section 4.2.6.

In making recommendations on the HEDs in this category consideration will be given to division of operator responsibilities, principal work arean during emergency conditions, and potential .for loss of slarm information/ delay in recognizing alarm conditions. Operator preference and potential engineering constraints in modifying the controls will also be addressed.

8. Maintenance and Administrative Requirements Needs for corrective action in this category will be evaluated with Operations based on review of problems that i

have or could result from the conditions identified in the HEDs. Input from I&C Maintenance will also be obtained.

4.3 Task 3 - Determine Recommended Corrective Actions i

Analyses will be performed to identify appropriate, enhance-ments, design changes, or other corrective actions to address the identified problems. The specific analysis will vary with the nature of the specific problem being addressed.

Some of the key specific issues in the~ development of recom-

, mended enhancements and design changes are outlined below.

, 1. Multiple Input Annunciators

a. Engineering investigation / analysis required to identi- l fy parameter input sources and logic, and to determine the effort required to provide separate annunciation.

b. Related issues of window location, priority coding,.

and legends.

c. Integration with overall annunciator panel layout and priority coding recommendations.

d. Integration with the development of overall panel labeling and window legend improvements.

1.0 INTRODUCTION

This study plan outlines _the methodology for evaluating computer-related HEDs generated during the Davis-Besse DCRDR. It also outlines the methodology for the development of appropriate resolutions for those HEDs. '

2.0 GUIDELINES The human factors engineering guidelines used to evaluate the Computer System are drawn from primarily from NUREG-0700, Section 6.7. Other sources in the research literature may be used during specific analyses.

3.0 SCOPE The Computer Special Study includes analysis, evaluation, and review to develop recommendations for effective-resolution of HEDs associat-ed with the Data Acquisition Display System (DADS). The specific HEDs addressed in this study are listed in Exhibit 1.

The Safety Parameter Display System (SPDS) is not within the scope of this special study. Checks will be made, however, for consistency where appropriate between DADS and SPDS. These checks will include, for example, use of color, terminology, and symbols, with the specifi-cations developed in the Labeling Special Study serving as the baseline.

Implementation of HED dispositions is not within the scope of this special study.

4.0 METHODOLOGY 4.1 Task 1 - Group and Investigate HED Concerns To ensure consistency in the analysis and resolution of Computer HED concerns, the HEDs in this study are divided into the follow-ing working groups. These may be modified as the study progresses.

1. Character Legibility and Display Readability i

2. Visual and Auditory Coding

3. Display Formats and Labeling

4. Data Access, Screen Messages, and Prompts

5. User Documentation

6. Terminals / Peripherals i

APPENDIX-B COMPUTER SPECIAL STUDY PLAN Page 2 Exhibit 2 lists the HEDs by working group.

The HEDs in each group will be analyzed to determine overlaps, and define any subgroupings that may facilitate integrated treatment of specific concerns. ;

Each group will-be investigated by screen and screen access review at the terminal, documentation-review, and discussions with Operations and Engineering personnel. The objectives of this investigation are:

To define HED problem descriptions in greater detail as necessary to fully understand and document the issues.

To identify and review any completed or initiated actions which may fully or partially correct an HED or may affect

the analysis in some other way..

J 4.2 Task 2 - Analyze Needs for Enhancement or Denian Improvement The operational implications of the concerns identified in the HEDs will be determined. These will provide the basis for-

, recommendations as to whether corrective action is necessary or desirable.

4 The analysis will be conducted in two parts. First, a prelimi-nary analysis of each working group will be done. This will.

involve screen review, criterion research, and measurements as applicable. Second,~ data and findings from the preliminary analysis will be used to develop an operator interview protocol,-

which will cover all analysis groups. Screens will be reviewed ~

t with operators to obtain their assessment of the effects of HED t concerns on the readability and usability of information. It will be determined whether HED concerns have been associated-with significant operational difficulties. During the prelimi-nary analysis, cumulative and interactive (C&I) effects as a

. factor in the significance of individual concerns will also be l considered.

4.3 Task 3 - Determine Recommended Corrective' Actions Recommendations will be developed for specific corrective [

actions. Major considerations in the development of these 3 recommendations are summarized below.

1.0 INTRODUCTION

This study plan outlines the specific methodology for evaluating control-related HEDs generated during the Davis-Besse DCRDR. It also specifies the methodology for the development of appropriate resolu-tion to those HEDs.

2.0 GUIDELINES The human factors guidelines used to evaluate the Davis-Besse Control Room systems and components during the DCRDR are from NUREG-0700.

These guidelines will also be used to evaluate the acceptability of proposed HED resolutions.

3.0 SCOPE The Controls Special Study includes analysis, evaluation, and review to develop recommendations for effective human factors resolution of related HEDs identified in the Davis-Besse DCRDR. The specific HEDs addressed are listed in Exhibit 1. This list includes HEDs which identify problems with the availability, location, or characteristics of control devices in the Control Room. Some HEDs in this Controls Special Study are also addressed in the PAM Panel or SFRCS Special Studies. This study will be coordinated with the Displays Special Study as they are inter-related.

Implementation of HED dispositions is not within the scope of this special study.

4.0 METHODOLOGY 4.1 Task 1 - Group and Investigate HED Concerns To ensure consistency in the analysis and resolution of Controls HED concerns, the HEDS in this study are divided into the following working groups. These may be modified as the study develops.

1. Missing Control Capabilities

2. Inappropriate Control Capability

3. Control Logic Problems

4. Control Device Design Problems

5. Problems with Control Device Operation

6. Control Device Location Problems i

8. Device Coding and Convention Problems

9. Other Control Proolens i i Exhibit 2 lists the HEDs by working group.

The HEDs in each group will be analyzed to determine overlaps, t and define any.subgroupings that may facilitate integrated treatment of specific concerns.

Each group will be investigated by panel review, documentation review, and . discussion with Operations, Engineering, and Mainte--

l nance personnel, as appropriate. The objectives of this inves-

! tigation are:

To define HED problem descriptions in greater detail as necessary to fully understand and docur.ent the issues.

j

To identify any components which should be added to or . l j deleted from the-list of components previously identified in~an HED. '

i i

To identify and review any. completed or planned actions which may fully or partially correct the HED or affect the

! analysis in any other way.

l 4.2 Task 2 - Analyze Need for Enhancements or Desian Improvements 4

The operational implications of the human factors concerns identified in the HEDs will be determined. The analysis will 4

consider whether a given problem is a single instance in the Control Room, or whether the specific type of problem is more 2

pervasive. Consideration of all the HEDs.in a working group together will, to an extent, address cumulative an interactive (C&I) effects among HEDs.

i Another C&I effect is that of multiple HEDs which apply to the

, same Control Room component. The potential exists for tne i aggregate effect of several human factors problems, each rela-1 tively insignificant in and of itself, to interact such that the 1

aggregate effect is substantial. Any recommendations which do not necessitate corrective action on a particular component under a specific HED, will be supported by a review of all HEDs

relative to the component to ensure that the aggregate effect is also acceptable.

For HEDs which identify a missi.g control capability (4.1.1) or l an inappropriate control capability (4.1.2), it will be deter-mined whether or not the required control action can be accom-plished effectively and without significant delay or error potential, with existing devices or through local operations.

APPENDIX C CONTROLS SPECIAL STUDY PLAN. ,

Page 3 For problems with control logic (4.1.3), control device design

-(<4.1.4), and control device operation (4.1.5) the nature and possibilities for resolution will be reviewed with Operations and Engineering personnel. HEDs in each of these working groups

address either the control loop design or the physical design of i the control and hardware, including internal functions. Review with Operations and Engineering personnel will yield both an assessment of the operational significance of the problem and '

the engineering constraints that must be' accommodated.

Problems with control device location (4.1.6) will be reviewed with Operations personnel. Where Operations identifies a problem as significant, review with Engineering personnel will be required to identify potential engineering constraints and considerations. For those HEDs where the nature of the problem is lack of association between a control and its associated '

display, close coordination will be required with the Displays Special Study to ensure consistent recommendations and assessment.

j Duplicate controls problems (4.1.7) will be reviewed with Operations to determine whether there is a legitimate opera-1 tional need. Based on this review, recommendations for removal

, of control devices from the Control Panels will be developed.

Control device coding and convention problems (4.1.8) identified I on HEDs do not involve the functioning of the control device itself. Rather, they address the operator's ability to find the appropriate control and execute the correct control action.

These primarily will be reviewed by the human factors. specialist d

and followed with.an Operations review to ensure that applied j conventions are acceptable and consistent.

1

( Other problems (4.1.9) will be addressed on a case by case 1 basis. Coordination and review with Operations and Engineering j personnel will be accomplished as necessary. l i'

4.3 Task 3 - Determine Recommended Corrective Actions Analyses will be performed to identify appropriate enhancements,

design changes, or other corrective actions to address ' problems.

l The specific analysis to be performed will vary with the nature '

j of the specific problem being addressed.

Potential relationships and interactions among the HEDs with respect to specific components will be considered. This will

involve review of multiple KEDs on a single component, . function-i ally related or collocated components, and coordination with other special studies.

DAVIS-BESSE DISPLAYS SPECIAL STUDY PLAN

1.0 INTRODUCTION

This study plan outlines the specific methodology for evaluating display-related HEDs generated during the Davis-Besse DCRDR. It also specifies the methodology for the development of appropriate resolu-tion to those HEDs.

2.0 GUIDELINES The human factors guidelines used to evaluate the-Davis-Besse Control Room systems and components during the DCRDR are from NUREG-0700.

These guidelines will also be used to evaluate the acceptability of proposed HED resolutions.

3.0 SCOPE The Displays Special Study includes analysis, evaluation, and review ,

to develop recommendations for effective human factors resolution of related HEDs identified in the Davis-Besse DCRDR. The specific HEDs addressed are listed in Exhibit 1. This list includes all HEDs which identify problems with the availability, location, or characteristics of display devices in the Davis-Besse Control Room, except for a limited number of specific HEDs more appropriately addressed in the Annunciator Special Study. Some of the HEDs in this Displays Special Study are also addressed in the PAM Panel and SFRCS Special Studies.

This study will be coordinated with the Controls Special Study.

Implementation of HED dispositions is not within the scope of this special study.

4.0 HETHODOLOGY 4.1 Task 1 - Group and Investigate HED Concerns To ensure consistency in the analysis and resolution of Displays HED concerns, the HEDs in this study are divided into the following working groups. These may be modified as the study-develops.

1. Missing or Inappropriate Displays

2. Display Location Problems

3. Display Range and Precision Problems

4. Display Logic and Design Philosophy HEDs

5. Indications of Eisplay Device Failure

6. Trend Recorder Problems t

10. Other Display Related HEDs' Exhibit-2 lists the HEDs by working group.

The HEDs in each group, will be. analyzed to determine overlaps 1 and define any subgroupings that may facilitate' integrated.

treatment of specific concerns.

j Each group will be investigated by panel review, documentation -

review, and discussions with Operations, Engineering,'and.

Maintenance personnel. The objectives of this investigation are:

,

To define HED problem descriptions _in greater detail as necessary to-fully understand and document the issues, a

f

To identify any components which should be added to or deleted from the list of components previously identified in an HED.

To identify and review any completed or planned actions that may fully or partially correct the HED or affect the analysis in any other way.

4.2 Task 2 - Analyze for Need for Enhancements or Design Improvements The operational implications of the human factors concernsL ~

identified in the HEDs will be determined. The analysis will consider whether a given problem.is an isolated instance in the i

Control Room, or whether the specific t'ype of problem is more pe rvasive. Consideration of all the HEDs in a working group together will, to an extent, address cumulative and interactive '

(C&I) effects among HEDs.

4-

Another C&I effect is that of multiple.HEDs which: apply to the same Control Room component. The potential exists for the aggregate effect of several human factors problems, each rela-tively insignificant in and of'itself, to interact such'that the aggregate effect is substantial. Any recommendations which'do-

' not necessitate corrective action on a particalar component ,

under a specific HED will be supported by a review of all HEDs '

relative to the component to ensure that the aggregate'effect is !

also acceptable. -I

' APPENDIX D DISPLAYS SPECIAL STUDY PLAN Page 3 For HEDs which identify a missing or inappropriate display (4.1.1), it will be determined whether or not the required ,

information can be provided effectively and without significant delay, error potential, or other adverse operational impact, using existing display devices or through local operations.

Problems regarding display device location (4.1.2) will be reviewed with Operations personnel. Where Operations identifies the problem as significant, further review with Engineering personnel will be required to identify potential engineering constraints and considerations. For those HEDs in this catego-ry, where the nature of the problem is lack of association between a display and its associated control, close coordination will be required with the Controls Special Study to ensure consistent recommendations and assessment.

HEDs addressing display range and precision problems (4.1.3),

will be reviewed with Operations to identify safety signifi-cance. The plant conditions dictating the requirements and/or operational impact will also be evaluated against the plant's functional task analysis. The HEDs will then be reviewed with engineering to determine potential hardware requirements and options to correct the problem (s).

HEDs regarding display logic and design philosophy (4.1.4) address issues with either the instrument loop design or the physical design of the display device hardware, including its internal functions. Review will be conducted with Operations and Engineering personnel to yield both an assessment of the operational significance and potential engineering constraints.

Problems with indication of display device failure (4.1.5), will be reviewed with Operations to determine the operational impact of a display device failure which is not noticed by an operator, who subsequently takes action based on incorrect information.

Considerations will include identification of other related displays that can help in diagnosis of a failed instrument.

Trend recorder problems (4.1.6) will be addressed as a group.

Review will be conducted with Operations personnel regarding the trend recorder's ability to display needed information, paper speed adjustment problems, and paper change problems. Mainte-nance related problems will be reviewed with I&C, Engineering, and Maintenance personnel.

Scale graphics (4.1.7) and pointer design (4.1.8) problems will be reviewed with Operations personnel to determine significance.

Scale graphics problems will be closely coordinated with the Labeling Special Study. In cases where a decision to replace a scale is made, all human factors problems associated with the i scale graphics on that indicator will be corrected.

Recommendations regarding pointer problems will be made on a case by case basis.

APPENDIX D DISPLAYS SPECIAL STUDY PI.AN Page 4 Display illumination HEDs (4.1.9) will be reviewed with Opera-tions to determine the operational information requirement and the operational implication of-the human factors problem.

Engineering personnel will be consulted for options to correc-tive actions.

Other problems (4.1.10) will be addressed on a case by case basis. Coordination and review with Operations and Engineering personnel will be accomplished as necessary.

4.3 Task 3 - Determine Recommended Corrective Actions Analyses will be performed to identify appropriate enhancements, design changes, or other corrective actions to address the identified problems. The specific analysis will vary with the nature of the specific problem being addressed.

Potential relationships and interactions among the HEDs with respect to specific components will be considered. This will involve review of multiple HEDs on a single component, function-ally related or collocated components, and coordination with other special studies.

4.4 Task 4 - Final Decision on Corrective Actions All recommendations -- both those concerning whether to take corrective action and those describing proposed corrective actions -- will be submitted to Operations and Engineering for review. Comments will be resolved before the recommendations are finalized.

Reviewed recommendations will be submitted to the HED Review Team for approval. Recommendations may be revised during Review Team meetings. Any revised recommendations will be resubmitted to Operations and Engineering for review and comment. Approved recommendations will constitute the final disposition of the HED.

To identify and review any completed or initiated actions that may fully or partially correct the HED or affect the analysis in any other way.

4.2 Task 2 - Analyze Need for Enhancements or Desian Improvements The analysis will consider whether a given problem is an isolat-ed instance in the Control Room, or whether the specific type of problem is more pervasive. Consideration of all the HEDs in a working group together will, to an extent, address cumulative and interactive (C&I) effects among HEDs.

Any recommendations which do not necessitate corrective action on a particular issue under a specific HED will be supported by a review of all other illumination HEDs to ensure'that the C&I

effects of are acceptable with respect to human factors and operational impact.

For HEDs which identify glare problems (4.1.1) it will be.

determined if non glare glass or plastic lenses can be used. At the other extreme, glare problems may be addressed by lighting

. system redesign or louver redesign to diffuse the light more a effectively. Similar trade-offs occur with the other illumina-tion problems identified with the Davis-Besse Control Room.

Attaining a uniform and adequate illumination level in the i

Control Room (4.1.2, 4.1.3, 4.1.4, 4.1.5) will require addition-l al analysis to determine specific illumination level inadequa-

cies. Further lighting surveys will be conducted to develop more detailed descriptions of the problem and determine effec-I tive options for resolving the HEDs.

4.3 Task 3 - Determine Recommended Corrective Actions Analyses will be performed to identify appropriate enhancements, design changes, or other corrective actions to address the identified problems. The specific analysis to be performed will vary with the nature of the specific problem being addressed.

4 Potential relationships and interactions among the HEDs will be considered.

1.0 INTRODUCTION

, This study plan outlines the specific methodology for the Labeling Study. Since all control room relabeling, demarcation and mimicking-

! will be implemented during the 5th refueling outage, schedule

! priority will be given to evaluating, developing recommendations, and j . implementing the control room relabeling effort.

2.0 GUIDELINES '

1 The human factors guidelines used to evaluate control room systems and components and to develop appropriate labeling and conventions are derived primarily from NUREG-0700. Other sources include MIL-STD-1472C and NUTAC-INPO 83-036. These guidelines will also be used to evaluate j the acceptability of proposed HED resolutions.

3.0 SCOPE l The Labeling Special Study will result in completely relabeling the main control boards.

l l The specific HEDs addressed in this study are listed in Exhibit 1.

CRT and keyboard labeling and conventions are considered under the Computer Special Study. Standards, acronyms, and abbreviations j developed during this study will however, be applied in the computer,

annunciator, and display studies.

l Implementation of HED dispositions is not within the scope of this study.

4.0 NETHODOLOGY Resolution of Labeling HEDs will occur through the relabeling of 3

Control Room - control boards. Therefore, the methodology for this study is as follows:

4.1 Task 1 - Develop Standardized Dictionary of Abbreviations, Acronyms and Symbols.

i Using established abbreviations and acronyms as a baseline, a dictionary will be developed. This dictionary will be reviewed and verified with Operations and Configuration Management.

APPENDIX G NOISE AND COMMUNICATION SPECIAL STUDY Page 1 DAVIS-BESSE NOISE AND C019fUNICATION SPECIAL STUDY PLAN

1.0 INTRODUCTION

This study plan outlines the specific methodology for evaluating noise and communication related HEDs generated during the Davis-Besse DCRDR. It also specifies the methodology for the development of appropriate resolution to those MEDs.

2.0 GUIDELINES The human factors guidelines used to evaluate the Davis-Besse Control l Room systems and components during the DRCDR are from NUREG-0700.

These guidelines will also be used to evaluate the acceptability of proposed HED resolutions, i

3.0 SCOPE The Noise and Communication Special Study includes analysis, evalua-tion, and review to develop recommendations for effective human factors resolutions of HEDs identified in the Davis-Besse DCRDR. The specific HEDs addressed are listed in Exhibit 1. This list includes all uncorrected Davis-Besse DRCDR HEDs which identify problems with the acoustic characteristics of alarms, the communication system and communication devices, and the acoustic environment in the Davis-Besse Control Room. A limited number of HEDs concerned with annunciator audible alarms, have also been included. The Noise and Communications ;

Special Study will be coordinated with the Annunciator Special Study. '

Implementation of HED dispositions is not within the scope of this special study.

4.0 METHODOLOGY 4.1 Task 1 - Group and Investiaate HEDs Concerns To ensure consistency in the analysis and resolution of Noise l and Communication HED concerns, the HEDs in this study are l divided into the following working groups. These may be modi- )

fied as the study develops. j

1. Intensity of Auditory Signal and Background Sound.

2. Verbal Communication Equipment.

3. Individual Verbal Communication Concerns.

Exhibit 2 lists the HEDs by working group.

I l . _ _ _ _ _ . _ _ _ _ _ _ _ -_ ~ . - - - - - - -

APPENDIX G NOISE AND COMMUNICATION SPECIAL STUDY Page 2 The analysis includes reviewing the HEDs and ensuring that the HED documentation is adequate, complete, and correct; that the information required to support further analysis of the problem is available, and that the identified problem still exists in the Control Room.

4.2 Task 2 - Analyze Need for Enhancements or Design Improvements 1 The operational implications of the human factors concerns l

identified in the HEDs will be determined. Consideration of all

) the HEDs in an analysis group together will, to an extent, address cumulative and interactive (C&I) effects among HEDs.

Another C&I effect is that of multiple HEDs which apply to the same Control Room feature. The potential exists for the aggre-gate effect of several human factors problems, each relatively insignificant in and of itself, to interact such that the aggregate effect is substantial. Any recommendations which do not necessitate corrective action on a particular item under a

, specific HED will be supported by a review of all HEDs relative l to that item to ensure that the aggregate effect is also

! acceptable.

j Several HEDs in the Annunciator Special Study address priority j coding and location coding of the auditory annunciator alarms.

1 Since some HEDs in the Noise and Communications Study address poor identification of alarms and interference of annunciator alarms with voice communications, it will be coordinated with the

! Annunciator Special Study. This will promote rapid identifica-tion of auditory alarms while permitting discernible verbal communication. The HEDs for auditory coding of annunciators were assigned to the Visual and Auditory Alert System category of the Annunciator Special Study to facilitate an integrated analysis of the visual and auditory components of the annunciator system.

]

Analysis steps to evaluate the operational significance and need for changes to resolve the HED concerns are summarized below for each working group of HEDs.

1. Intensity of Auditory Signal and Background Sound. The HEDs in this category refer to sound levels either being too high or too low. Some concerns will be evaluated relative to each other. (For example, an alarm which is reported to be difficult to hear may have an adequate sound level if the general ambient noise level is reduced. In a similar manner, alarms that are considered too loud may i have been set high in order to ensure sigual recognition over high background noise.)

i k

APPENDIX G

NOISE AND COMMUNICATION SPECIAL STUDY Page 3 Measurements of Control Room noise levels over an extended '

period of time and the sound levels of alarms-will be

.taken. These measurements will then be compared to recom-mended optimal levels. The noise level measurements will also be used to investigate signal to noise ratios. In-i addition, observation and documentation;of noise will be required to allow study team members to identify chronic

and intermittent sources and their effect on Operations lI 2. Verbal Ccamunications Equipment. These HEDs'are concerned

, with problems in using communication equipment in everyday j situations and with protective equipment. Five of -the HEDs address the possibility of not hearing messages. Investi .

! gation of these concerns will determine if hearing is l truely impaired when important messages are transmitted through these devices, and whether reliable back-up systems i are available. Operators will be observed in the situations j cited in the HEDs. Word and syllable intelligibility tests

! with operators using the communication equipment may be j used by team members to determine which problems exist.

3. Individual Verbal Communications Concerns. For HED 2.1.001,.

, discussions with Operations personnel and if necessary,

{ Security and Emergency Planning personnel will determine if an adequate procedure currently exists for handling commu-

, nications during an emergency.

HEDs 1.1.004 and 1.1.005 will require investigation of -

current communication links between the Shift Supervisor's office and the Control Room. Interviews with. Control Roon j personnel and Shift Supervisors will be coordinated with

the Operations Special Study.

i j 4.3 Task 3 - Determine Recommended Corrective Actions Analyses will be performed to identify appropriate enhancements, design changes, or other corrective actions to address the identified problems. The specific analysis will vary with the

nature of the specific problem being addressed.

1 Potential relationships and interactions among the HEDs with

! respect to specific components will be considered. This will t

involve review of individual and multiple HEDs on the' Control Room acoustic environment and coordination with other special j studies.

To define HED problem descriptions in greater detail ~

as necessary to fully understand and document the' issues.

To identify any. components which should be a'dded to the list of components previously identified in an

To. identify and review any. completed or initiated actions that may fully or. partially. correct'the HED or affect the analysis in any other way.

4 4.2 Task 2 - Analyze Need for Enhancements or Design Improvements The operational implications of the human factors concerns identified in the HEDs will be determined. It will then be i determined whether the identified human factors. problem is sufficiently significant such that a change is needed or j desirable.

The analysis will consider whether a given problem is'an isolat-ed instance in the Control Room, or whether the specific type of-problem is more pervasive. Consideration of all the-HEDs in a working group together will, to an extent, address cumula-l tive and interactive (C&I) effects-among HEDs.

3 Another effect is that of multiple HEDs which apply to the same, j Control Room component. The potential exists for the aggregate effect of several human. factors problems, each relatively j insignificant in and of itself, to interact such that<the 7 aggregate effect is substantial. Any recommendations which do

! not necessitate corrective action on a particular component, under a specific HED, will be supported by.a review of all.HEDs

~

APPENDIX J-PAM PANEL SPECIAL STUDY PLAN Page 1 DAVIS-BESSE PAM. PANEL SPECIAL STUDY PLAN

1.0 INTRODUCTION

This task plan outlines the. specific-methodology for evaluating HEDs affecting panels C5798 and C5799 -(PAM Panels) generated during tha Davis-Besse DCRDR. It also specifies the methodology'for the devel-opment of appropriate resolution to those HEDs.

Preliminary analysis of the concerns identified on these panels has raised the possibility of a rearrangement of components which must be completed by the end of the 5th. refueling outage. Although this may not be necessary after final analysis, this study plan is

organized around a redesign of. Pam Panel layout. If it.is not necessary to modify the layout, then HED resolution will proceed in a J

manner similar to the other special study plans.

2.0 GUIDELINES The human factors guidelines used to evaluate the Davis-Besse Control Room systems and components during the DCRDR are from NUREG-0700.

These guidelines will also be used to evaluate the acceptability of proposed HED resolutions.

3.0 SCOPE i

The PAM Panel Special Study includes analysis, evaluation, and review of_ panels C5798 and C5799 to develop recommendations for effective -

human factors resolution of PAM Panel related HEDs. The specific HEDs addressed are listed in Exhibit 1. Some of these HEDs are also being addressed in other special studies.

Implementation of HED dispositions is not within the scope of this special study.

4.0 METHODOLOGY This work plan is composed cf seven tasks which include a require-ments analysis, a design and evaluation process, and a final review of the reccamendations.

4.1 Task 1 - Assemble and Evaluate HED Concerns. 1 i

All HEDs concerned with these panels will be reviewed to deter-1 l

mine those which need to be corrected. This will be the driving I force in defining constraints on panel redesign. '

APPENDIX J-PAM PANEL SPECIAL STUDY PLAN Page 2 4.2 Task 2 - Identify Instrumentation and Control Requirements

. Instrumentation and. control. requirements will be determined based on panel review, a. review of HEDs, and a review of corre-spondence between. Toledo Edison and the NRC.regarding Regulatory Guide-1.97. Additionally the DCRDR Task Analysis will be reviewed and a list of functions and components for the panels will be compiled.

This special study will be coordinated closely with other Special Studies.

4 4.3 Task 3 - Identify Hardware for PAM Panels This task will identify specific. component types which provide i

required instrumentation and control functions for these. panels.

4 Using the list of instrumentation and control requirements, existing and new instrumentation will be examined.

4.4 Task 4 - Develop Preliminary Instrument Arrangement:

Functional relationships between instruments placed on these panels will be examined for consideration of functional grouping

! and spatial relations. As appropriate, requirements from other i special study plans will be examined for related considerations.

Anthropometric constraints will be imposed to promote effective j visual and reach requirements.

Preliminary sketches.of the panels will be developed. . Labeling 1

and graphics will be shown on the sketches. The labeling and graphics recommendations developed in the Labeling Special Study will be incorporated.

4.5 Task 5 - Evaluate Preliminary Panel Arrangement The preliminary panel arrangement will be evaluated as follows:

i i

Review preliminary sketch (s) with Operations and Engineering and discuss differences between the existing l and the new proposed layout.

Interview operators with regard to operational effective-4 ness of new panel layout with respect to E0Ps.

Review comments with Operations and Engineering to deter-4 mine appropriate resolutions.

.* Evaluate panel with regard to relevant HEDs.

'st APPENDIX J PAM PANEL SPECIAL STUDY PLAN Page 3 4.6 Task 6 - Refine and Finalize Recommendations The design recommendations will be refined and finalized as follows:

Comments on preliminary design will be incorporated into sketches.

Final design recommendations will be evaluated by Opera-tions and Engineering.

All PAM-related HEDs will be reviewed to ensure that they have been addressed as required.

Information necessary to guide implementation of the recommendations, including detailed description of capabil-ities, surface characteristics, and conventions will be prepared.

Final evaluation considerations and any significant tradeoffs will be recorded.

4.7 Task 7 - Final Decision on Corrective Actions All recommendations will be submitted to Operations and Engineering for review. Comments will be resolved before the recommendations are finzalized.

The study recommendations will be submitted to the HED Review Team for approval. Recommendations may be revised during the Review Team meetings. Any revised recommendations will be resubmitted to Operations and Engineering for review and com-ment. Approved recommendations will constitute the final disposition of the HED.
