SECTION 1'NTRODUCTION This report describes the results of the supplemental Detailed Control Room Design Review (DCRDR) efforts for Rochester Gas and Electric's (RG&E) Ginna Station. Included is a description of the follow-on studies that have been completed since the Ginna Station Final Summary Report was submitted December 30, 1985.

The Safety Evaluation Report (SER), dated September 4, 1986, for Ginna recommends that certain actions be taken to fulfill the DCRDR requirements of Supplement 1 to NUREG-0737. This report addresses each of the NRC findings described in the SER, and the conclusions presented in the Technical Evaluation Report (TER).

Table l-l lists the section of this report which covers. each of the NRC findings. Included in Section 3 are complete explanations of-all of the items discussed in the conference call held between RG&E and the NRC on November 12, 1986. As a result of the follow-on studies performed by RG&E, several Human Engineering Discrepancies (HEDs) were revised to more accurately reflect the current response. Each of these HEDs was presented to the DCRDR committee members for review. The Revision 1 HEDs are listed in Appendix A.

SECTION 2 RESPONSES TO SER/TER CONCERNS This section provides specific responses to each of the NRC concerns expressed in the SER and the conclusions listed in the TER.

F 1 In- ro ress Audit HEDs The Results of the In-progress Audit of the Detailed Control Room Design Review Report for Ginna nuclear power plant, dated August 9, 1985 listed several HEDs identified by the audit team that were not identified as part of the checklist survey. There were various reasons for these omissions in all cases. Either the items cited by the NRC audit team were not considered HEDs by the RG&E CRDR review team, or were considered generic and not specifi-cally cited by RGSE, or, in the case of the control room lighting, the problem was considered marginal. A generic HED, such as indicator scale problems, evolved during the course of the design review when it was realized that many HEDs being generated were addressing a common problem. At this point a "study" of the common problem was identified and no further specific HEDs for the problem were initiated.

Nevertheless 'ach item cited by the NRC audit team was rein-t vestigated by the CRDR review team. The following paragraphs address each of the NRC audit team's concerns.

2~1~1 "Unlabeled scales were noted on FI-2011 and FI-2012."

"Handwritten scales that do not meet legibility criteria were noted on FI-2011, FI-2012, TI-2091, and PR-420."

Several HEDs were written to identify problems with display scales and labeling. Both indicating scale problems and labeling problems became generic HEDs. In this particular case, the labeling deficiency was corrected during the course of the control room paint, label and tape (PLT) modification program.

The PLT program has greatly enhanced the control board through a comprehensive effort involving repainting of all control cabinets, replacement or installation of new labels and demarcation of functional groupings. This effort was coordinated with efforts to provide unique, consistant identification of plant systems and components. Most of these modifications were made during the 1987 outage. The specific scale problems noted during the audit were addressed in the comprehensive study of all indicating scales. New scales to correct all deficiencies, including those identified by the audit team, have been ordered and are expected to be installed in September 1987 correcting in total the concerns of this HED.

"Protective covers over the valve control switches obscured the switch escutcheons. The controls for PCV-430 and PCV-431 are two examples of this HED."

This-was not considered an HED by RGGE since it was felt that the very purpose of the cover plate was to cause the operator to purposefully lift the cover plate and read the escutcheon before initiating action. However, it was recognized during the course of performing a generic study of escutcheon plates that some plates had become worn over the years and also, that consistency of language on plates was a problem. This study resulted in installing 246 new escutcheon plates including those plates specifically mentioned in this NRC concern.

"A few J-handle switches were noted to be close to the front edge of the control panel benchboard, and subject to accidental activation."

The shafts of the cited J-handles are three inches from the edge of the benchboard which is in compliance with the NUREG-0700 guideline; therefore no HED was written. In the 18 years that the Ginna plant has been in operation, there has never been a problem with accidental activation of these J-handles.

)II t

2 ' ' "A few contr'ol, switches, th'e Containment. Depressur-ization Valve controls, for example; were noted to have open/closed positions ."reversed from other control l( i switches."

The proper orientation and identification of switch positions has been carefully examined throughout the Ginna control room. New escutcheon plates have been installed on control switches to ensure that each switch position is clearly identified. In the process of performing the generic escutcheon plate study, all switch positions were examined for proper orientation to ensure that switch movement was consistent with the population stereotype.

Exceptions to this human factors principle are the Foxboro controllers (Section 3.4) and the cited control switches (Contain-ment Depressurization Valve Controls). These control switches are affected by a major modification to the containment mini-purge system and are scheduled to be removed from the control room in accordance with EWR 2504 during the 1988 refueling outage.

2 ~ 1.5 "The control room survey did not identify readily apparent problems with control room lighting levels and glare on displays. For example, high luminance ratios between information and veiling reflectance was noted by the audit team and the operator survey but not by the DCRDR lighting survey."

t'"

IJ tt

'C

The original lighting survey determined that lighting levels were marginal in some areas of the control room. This was verified by the NRC audit team. The survey program was restructured and a new lighting survey performed. This survey indicated that the existing lighting system was inadequate in some <areas. As a result, a completely new lighting system was installed in the control room which corrected the inadequacies.

2.1.6 "Lighting provided for access to and operation of safe shutdown equipment did not appear to be sufficient to provide the minimum illumination levels recommended by the XES handbook and NUREG-0800, Section 9.5.1."

Ginna safe shutdown panels are located in several areas of the plant. The lighting at the safe shutdown areas is sufficient to perform all required safe shutdown tasks. The lighting survey was conducted in conjunction with compliance efforts to meet 10CFR50 Appendix R and the lighting levels have been found to be acceptable. While RGGE is confident of Ginna's remote shutdown capability, it is our position that remote shutdown panels are not within the scope of the DCRDR.

2~1~7 "A valve

),

control switch label that does not functionally

~

describe the controlled device. Valve No. 350."

"Breaker control pushbuttons on panel 5, that did not describe the function of the control."

r l'

RG&E initiated a comprehensive labeling program to provide,.

unique, consistant labels. This labeling program involved the changeout of every label on the: main control board panels and the majority of the ancillary panels. Labels were color coded in accordance with a system color designation (See Section 3.3). In cases where dynotape was used to convey useful information to the operator such as set points, limits of operation, etc., permanent labels were installed utilizing a distinctive color. In all cases, the wording of the labels was reviewed to ensure that the function of the component was adequately described.

2~2 Assessment HEDs The following sections describe the RG&E activities to resolve the cited assessment concerns.

2.2 ' Annunciator HEDs All of the annunciator related HEDs were reviewed to determine

'he actions that must be taken to improve the annunciator system and resolve the HEDs. Two separate studies were conducted. The

~

first study, performed by RG&E operations and engineering person-nel, examined the operational design of the system. The only modification proposed as a result of the study was the installation of reflash capability. This proposal was rejected by the GARD*

Committee.

The operators at Ginna have received much of'heir training at the Zion Station simulator which has reflash capability. The Ginna operators decided against installing a reflash capability because they feel that it contributes significantly to the number of nuisance alarms in the control room. The second annunciator study was performed by ARD with assistance from plant operations personnel. This study examined annunciator tile nomenclature and location. The study established a standardized format for the wording of annunciator tiles and utilized a standard abbreviations list to ensure consistency.

• The GARD Committee consists of five licensed Ginna operators selected from different working shifts. The purpose of the committee is to provide operations support in the development of control room design modifications and to represent the unified position of all control room operators in DCRDR Committee matters.

The GARD Committee works with human factors specialists in the selection of a design from among alternative human factors solutions to a cited control room deficiency. Operator acceptance is essential to the effectiveness of any human factors-related modification; the existence of the GARD Committee assures accept-ance of the modification because operators have had a significant input in the development of the modification.

10

An individual annunciator window identification system was determined to be appropriate and will be adapted to the annunciator system. All new annunciator tiles have been ordered'. Approxi-mately fifty percent of the tiles required a change because of nomenclature, format, and/or lack of information. All tiles are to be individually engraved with an identifying number. The resulting changes improve the annunciator system and meet accepted human engineering design requirements. The tile replacement is expected to be completed in September 1987.

2 '.2 Lam Test Ca abilit Lamp test in the Ginna control room is performed by Procedure No.

0-6.13, Daily Surveillance Log. This Procedure must be performed and logged by operators on each shift. The Daily Surveillance Log lists every safety-related component in the control room and the operator must check that the appropriate status light for each of these components is lit. The procedure also includes a check of the bistable status lights (these are constantly lit) and all annunciator tiles (these have a lamp test pushbutton).

Performance of this procedure during each operating shift assures that all signif icant control room lamps have been observed as operational. If a lamp is burned out, the bulb is replaced immediately or a trouble card is submitted to assure the repair of the trouble source.

11

2 ' ' Remote Shutdown HEDs Ginna safe shutdown panels are located in several areas of the plant. Because of the component level based configured design, RG&E does not consider the remote shutdown panels a part of the DCRDR. Nevertheless, lighting surveys and procedure walkdowns have been conducted throughout the plant in conjunction with 10CFR50, Appendix R compliance and the lighting levels have been judged acceptable.

2 ' ' Controller for Steam Generator Water Level Durin

~Startu The RG&E Engineering Department and Ginna I&C have investigated many alternatives in trying to improve the steam generator water level control system. Different plant parameters such as nuclear power, steam generator level, feedwater flow, steam flow and reactor power, have been investigated in different combinations as controlling signals to the feedwater valve controllers with little improvement realized. Recently, during the last refueling outage, a new calibration procedure was utilized which appears to have improved steam generator level control considerably during startup.

12

I RG&E is still pursuing the problem actively. RG&E is also an active participant in the. Westinghouse WOG TRAP program and, if

')J h ))

appropriate, will utilize the results of this program at Ginna.

2 ' Status of Desi n Xm rovements The following sections list the status of the design improve-ment studies that RG&E committed to in the Final Summary Report.

2.3.1 Annunciator Desi n Stud The annunciator design studies, described in section 2.2.1 are complete. Replacement of annunciator tiles will take place in September 1987.

2 '.2 Auditor Alarms An extensive sound level survey was performed in the Ginna control room. This effort required measurement and data recording of Sound Pressure Levels (SPLs) for determination of control room ambient. sound level and acoustic profiles of the various alarm systems. Data was used for quantitative evaluations and decision-making. Tape recordings were used for assessing recognition, distinctive coding, and interaction/masking between alarm systems.

13

I, Ambient sound level surveys and alarm measurements were conducted in April and May 1987. Sound level data and alarm. signals were measured or recorded at the center of the primary operating area.

Il The data was used to make recommendations to resolve the HEDs cited regarding the auditory alarms. NUREG 0700 recommends that alarm levels should be 10 dBA above ambient noise level. The Ginna annunciator alarm is 6 dBA above ambient and found to be acceptable as well as desirable. The external alarms are initiated and sound in the control room over the PA system. A variable muting will be installed on the PA system to allow the external t

alarms to be adjusted to a level within 2.5 dBA of the annunciator alarm. The fire panel alarms" will'~be replaced by'. variable electronic chimes by June 1988. These electronic chimes, which are UL approved fire alarms, will be adjusted to be within 2.5 dBA of the annunciator alarm.

2.3.3 Volatile Treatment B ass Valve Controller The need for an All Volatile Treatment (AVT) Bypass Valve control-t ler was reviewed by the GARD Committee. Their recommendation to the CRDR Committee was that no change be made. There is an annunciator in the control room to alert the operator of any 14

I alarm at the AVT ,panel; Since, an auxiliary operator must, be dispatched to the AVT panel (which is a short distance away) whenever this annunciation alarms, it is no more of a burden to respond to a bypass valve activation than for any 'other AVT system alarm problem.

2.3.4 Valve Position Indications A study to examine the need and feasibility of valve position indications for main feedwater regulation valves and feedwater bypass valves is complete. It has been determined that these indications will be helpful to the operators in some cases for controlling steam generator level. They are scheduled to be installed on the control boards in June 1988.

2 ' ' Im roved Inkin S stem for Chart Recorders A study to determine the best method to improve the inking of strip chart recorders is complete. A new type of pen has been installed in all Foxboro chart recorders which alleviates the problem of smeared ink on the chart paper. The new inking system has been found to be reliable and to provide clean distinctive markings.

2 ' ' Status Li ht Discrimination The problem of discrimination of status lights that show conditions by a bright or dim indication has been solved by removing and cleaning the lenses and by replacing the light bulbs with bulbs of the proper voltage rating. Bright or dim indication is now easily discernable. In addition, further studies have demonstrated that introducing a voltage dropping resistor into each status light circuit also improves discrimination. A few circuits have been modified with dropping resistors and it is intended that all circuits will be modified in the future. However, this enhancement is not required to provide an acceptable level of discrimination.

2.4 Verification of Future Modifications A continuing human factors program is being developed and will include operations and engineering support in the human factors effort and a human factors design manual. All modifications affecting the control room are being reviewed by RG&E's human engineering consultant, until the design manual is implemented by RGGE.

2 ' Coordination of Control Room Im rovements The coordination of the CRDR with NUREG-0737, Supplement 1 initiatives, including Regulatory, Guide'",1.97 and SPDS has been assured by using a common basis for development of the personnel managing these programs. The new EOPs, developed from the Westinghouse Owner's Group Emergency Response Guidelines (ERGs) serves as the basis for all of these programs. The EOPs were used to perform the DCRDR task analysis. The development of the SPDS display parameters was also based upon EOP requirements.

The DCRDR checklist survey was performed upon the SPDS displays.

Regulatory Guide 1.97 instrumentation was included in the DCRDR task analysis verification of suitability and checklist survey.

The new EOPs have been used for operator training in the new simulator since it has become operational.

The interrelation of all of these programs assures the coordination of control room improvements. The Ginna simulator now serves as the test vehicle for insuring that the implementation of all operational modifications is integrated as part of the RG&E human factors program.

2 ' 0 erator Surve Res onses The responses to the Operator Survey have been given careful consideration by RG&E. A copy of the operator survey responses was provided to the Ginna plant management to ensure that they were aware of the opinions of their operations staff.

Some of the operator concerns that were not cited as HEDs have been implemented (e.g., Tave display, modifications to control room door closer); however, many of their concerns will not be implemented for one of several reasons. In some instances,, '

concern was expressed by an operator but there was disagreement among the operators regarding the actual benefit of the suggestion.

In other cases, the responses were "nice to have" suggestions that are not given high priority because they do not represent a safety concern. All responses were given to all operators to provide the opportunity to develop support for their individual ideas or concerns. No significant issues were developed from this informal review.

18

II i SECTION 3 CONFERENCE CALL ISSUES

! P 1 A conference call was held between NRC licensing personnel and RGGE personnel on November 12, 1986 to discuss and clarify some of the items included in the SER. As a result of this call 4 some of the studies identified in the CRDR Summary Report were accel-erated. These studies, some of which were the Controller Study, Auditory Alarm Study, and Annunciator Study are now all complete.

The call also raised new topics that the NRC requested that RG&E discuss in the supplemental summary report which are included in this section. Table 3-1 lists the topics discussed during the conference call and the sections of the supplemental summary report that, addresses each of the issues.

3 ' EOP Develo ment The new EOPs were subject to a detailed verification and valid-ation process prior to their implementation. Operators use EOPs to perform their training in the Ginna simulator. This provides an ongoing validation of the EOPs, and assures that any deficien-cies are identified through their continued use.

The August 1986 NRC Information Notice (and its supplement) on procedure development was the topic of a meeting of the Ginna Emergency Procedure Committee. The concerns expressed in the information notice were addressed by the committee to ensure that they were in full compliance with the guidelines discussed in the NRC Information Notice.

3.2 Re ulator Guide 1.97 Modifications The Ginna review of Regulatory Guide 1.97 is based upon the EOPs which also provide a basis for the CRDR task analysis. Thus the two tasks have been closely coordinated and are based on the same operator actions and information requirements. All modifications, including those made relative to Regulatory Guide 1.97 are subject to human factors review. RGGE's ongoing human factors program, described in section 2.4, will ensure that modifi-cations do not create new human factors problems in the control room.

22

3 ' Colored Labels The use of colored labels instead of background shading to identify systems and functional grouping was carefully researched and tested. A background shading scheme was originally proposed and illustrated on a control panel mockup. Operator questionnaires and interviews regarding the background shading showed that operators disliked much of the background shading. Most operators admitted the utility of system identification but most thought that the background shading cluttered the control panels.

Another attempt was made to develop better background shading.

Templates, painted the, colors of the proposed background scheme, were cut to fit the appropriate panel areas and applied to the simulator control panels. This was evaluated by operations and generally received a negative reaction because the contrast of the many colors was distracting to the eye.

Zt became apparent, at this point in time, that it was difficult to develop a unified position from the full complement of operators for selection and verification of enhancement modifications. A representative group, the GARD Committee (Section 2.2.1) was formed to assist in finalizing an enhancement program.

Reverse engraved colored labels were then tried as an alternative to background shading. The advantage of using reverse engraving is that. the light lettering cannot accumulate dirt and it thus 23

maintains contrast. The background color of the labels and the color of the lettering (black or white) was carefully matched to ensure high contrast and visibility. Because of the concentration of controls and displays on the Ginna control panels the colored labels provide the perceptual cues to link together and identify instrumentation of individual systems at a glance. The operators are far more comfortable with the colored label identification scheme than with any of the proposed background shading schemes.

A colored hierarchical labeling scheme coupled with demarcation lines is a very effective method of system and functional grouping, especially on small control panels such as those at Ginna Station.

Operator response to the colored labels and demarcation has been positive. The combined program resolves the human factors concerns addressed in the original HED's.

HED responses which cite background shading as a corrective action have not been changed because it is felt that the colored label scheme is the equivalent to background shading.

3 ' Foxboro Controllers A comprehensive human factors study of the controllers in the Ginna control room was performed by ARD in response to several HED's. The results of this study indicated that there was a lack of information on all controllers. In addition,'GC personnel I

investigated an alternative solution to the unconventional 24

g I' indicator movement. which consisted of replacing the present controllers on a one-for-one basis witha new controller,. One of I

the new controllers was mocked up in a control loop to provide the Operators an opportunity to become familiar with its character-h istics. The Operators found the new controller to be unacceptable, and from a human factors standpoint, it was unreasonably compli-cated. For example, since each controller has a self contained microprocessor, six control push buttons and three scales are located on the face of the controller. All scales and push buttons are required by I&C technicians for programming but only some of the push buttons and all scales are required by the operators for control. Based on these results, it was concluded that the appropriate action is to modify the present controllers by adding informational labels as suggested by the ARD study.

Labels have been delivered and installation is to be completed by July of l987.

An extensive study of the control room alarms has been completed. The cited alarms are initiated in the control room and sound in the control room over the PA system. A variable muting will be installed on the control room PA system so that the intensity of the alarms can be modified so that they are within 2.5 dB of the annunciator alarm. The work will be completed by 6/88.

Auditory signals do not provide localization cues that direct operators to those control room work stations where their attention is required.

QQMMEIITQ:

It is difficult to discriminate between the alarms for the fire protection system and. the SPING system. Also, there is no localization of annunciator tones to the appropriate panel.
