1.0 INTRODUCTION AND BACKGROUND

I Supplemental Report 11 presents the results of tasks performed for the Hope Creek Generating Station (HCGS) detailed Control Room Design Review (CRDR) since the submission of Supplemental Report I to the NRC on December 27,1985.

I 1.1 Scope of Supplemental Report II Public Service Electric and Gas Company (PSE&G) submitted a Summary Report for the Hope Creek Generating Station detailed Control Room Design Review (CRDR) on August 6,1984. The HCGS CRDR Summary Report presented the results of the CRDR for all activities which had been completed. Certain analyses could not be completed by that time because of plant construction status. Those analyses and activities were clearly identified and a commitment was made to submit supplemental reports describing the results of those activities.

The NRC conducted a pre-implementation audit of the CRDR at HCGS, November 13 to November 15,1984.

During the pre-implementation audit, Public Service Electric and Gas made several commitments to the NRC regarding completion of the HCGS CRDR. These commitments are described in a letter to the NRC from PSE&G dated December 6,1984.

A summary of tasks completed and the status of HCGS with respect to each commitment were submitted in the CRDR Supplemental Report I on December 27,1985.

Results of tasks remaining to be completed after submission of Supplemental Report I are incorporated into this Supplemental Report II. These tasks are outlined below.

I 1.1.1 Control Room Surveys As stated in Supplemental Report I (page 2), surveys for Operator Interview and l Ambient Noise were to be completed after the plant had been in operation. HVAC, Illumination, Emergency Equipment and Communication Surveys were completed after l final installation of the respective systems and provision of emergency equipment. The results of these surveys are included in Appendix B of this report.

As also noted in Supplemental Report I (page 2), back panel 10C604 was not installed soon enough to complete a review and include the results in Supplemental Report I at the time of that report. The results of the survey of Back Panel 10C604 are also provided in l Appendix B of this report.

I 1.1.2 Review Implemented DCPs As noted in Supplemental Report I (page 2), the Design Change Packages (DCPs) were reviewed for human factors concerns. The installed DCP modifications to the control boards were reviewed by examining related documentation (related HEDs, DCPs, human factors comments to DCPs, and panel drawings); observing and measuring the installed modifications using NUREG-0700 criteria; and querying operations and I&C personnel about the modifications.

After analysis of this information, the human factors specialist completed a Human Factors Verification of Design Improvement form (Figure 1) for each DCP, documenting I resolution of the related HED(s) and determining whether the modification introduced new HEDs. All implemented DCPs were reviewed by a human factors specialist. A few items requiring corrections (mostly labels) were recorded during the review. Results were submitted to PSE&G, who has implemented a correction schedule to address these items.

I 2.0 METHODOLOGY 2.1 Control Room Surveys I 2.1.1 Objective The objective of the Control Room Surveys is to examine the control room equipment at a component level to identify and record any departures from accepted human engineering practices and standards. The Control Room Surveys were based on the I application of the criteria from Chapter 6 of NUREG-0700, using the task plans described in the Summary Report. These task plans were used to guide the survey data collection effort and facilitate systematic evaluation of the HCGS control room 0700 criteria.

The surveys remaining to be conducted after submission of Supplemental Report I include the following:

o Heating, Ventilating and Air Conditioning (HVAC) o Illumination o Ambient Noise o Communications o Auditory Alarms o Emergency Equipment.

The following sections give a brief description of the basic methodology and measurement conditions for each survey.

2.1.1 Heating, Ventilating and Air Conditioning (HVAC) Survey

a. Methodology - The basic methods used for the HVAC Survey were observation and measurement. Measurements of dry-bulb and wet-bulb temperature were made by an internally aspirated Bendix Model 566 Psychrometer. Measurements of air velocity were made with a hot wire annemometer supplied by PSE&G. Measurements were made at 13 I locations throughout the control room, 7 in the primary operating area and 6 in the back panel area. Seven additional air velocity locations were mensured where strong drafts were observed.

I b. Measurement Conditions - The measurements and observations were made during a time when the HVAC equipment was in its normal operating state.

2.1.2 Illumination Survey

a. Methodology - The basic methods used for the Illumination Survey were measurement and observation. All measurements were made with a 5 5

P Tektronix Model J-126 Photometer with a Model J-65 Cosine corrected Illuminance Probe and Model J65231 degree Field Illuminance Probe,

b. Measurement Conditions - Three basic conditions of lighting were r measured: 1) nonessential, 2) essential and 3) battery backup. In

( addition, the battery backup condition was measured both immediately after transfer to battery power and again later after the batteries had been supplying power for the design basis duration. For normal non-essential (diesel-backed) lighting, control room dimmers were in the full bright position. Measurements were made at 50 locations throughout the control room, 29 locations in the primary operating area and 21 locations in the back panel area. The Remote Shutdown Panel was also measured.

At most of these locations, 5 different verticallevels were sampled: 1) top of panel (annunciator), 2) upper panel (vertical board), 3) lower panel (sometimes benchboard), 4) floor and 5) clipboard level (about 40 inches {

above the floor). Both illuminance in foot-candles (ftC) and luminance in foot-Lamberts (ftL) were determined.

2.1.3 Ambient Noise Survey

a. Methodology - The basic methods used for the Ambient Noise Survey

( were measurement and observation. All measurements were made with a General Radio Type 1982 Sound Level Meter with Octave Band Filter.

The meter was calibrated before and after each measurement series.

b. Measurement Conditions - The following noise conditions were measured:

1) normal dayshift ambient noise at about 2 p.m. with approximately 10 people in the control room, 2) evening quiet conditions at about 9:30 p.m., and 3) morning quiet conditions at about 6:30 a.m. Both of these

{ latter conditions represented periods of less activity, with 2-15 people present in the control room.

2.1.4 Communications Survey

a. Methodology - The basic methods used to conduct the Communications Survey were observation, interviews, measurement, experimentation and study of drawings and documentation. The following communication sub-systems were reviewed: 1) page party public address / intercom system,

2) telephone system, 3) radio system, and 4) electro sound powered system. Listening observations were made with all systems to estimate sound quality and speech intelligibility. Brief experiments were con-ducted on the use and effectiveness of various subsystem components, including tests of communication capability over the telephone, page-party handset, and walkie-talkie portable radio while wearing protective breathing masks. Two types of masks were tested: 1) MSA Ultra Twin respirator mask and 2) Scott 4.5 SCBA oxygen mask. The effectiveness of the public address /page party intercom system was assessed by a plant walk-through of most of the major industrial spaces: reactor, turbine, radwaste, control, auxiliary and diesel generator buildings.

Paging messages were originated and listened to, magnetic tape record-ings were made, and A weighted sound levels were measured in noisy and/or reverberant spaces. The effectiveness of the telephone system (access, traffic-handling) and of the radio system (coverage, dead spots) were determined by operator laterviews. Measurements were made of 6

I I telephone handset and page party handset cord lengths in the control room, as well as background noise levels and sound spectra as a part of I b.

the Ambient Noise Survey.

Measurement Conditions - Measurements were varied as indicated above under normal plant operating conditions.

I 2.1.5 Auditory Alarms Survey I a. Methodology - The basic methods used for the Auditory Alarm Survey were measurement and observation. The details of this methodology were identical to those of the Ambient Noise Survey in terms of I b.

instrumentation, quantities measured, sampling locations and times of measurement.

Measurement Conditions - Seventeen auditory alarms were identified and I measured at 11 different locations throughout the control room. All alarms were also measured close to the sound source (within two feet).

Each alarm was sounded continuously for about 30 minutes while the measurements were being taken. Observations of sound quality, sound I localization and signal detectability were noted throughout the measure-ment sessions. Operators were also interviewed, particularly concerning false alarms.

2.1.6 Emergency Equipment Survey Evaluation of emergency equipment was performed by a human factors specialist using interviews and observation to assess relevant criteria of emergency equipment. A control room operator assisted the human factors I specialist by locating the emergency equipment and answering questions regarding availability, usability and maintainability.

2.2 Operating Personnel Survey 2.2.1 Objective i The Operating Personnel Survey was conducted by operator interviews. The purpose of the operator interviews was to draw on the experience of qualified, users of the control room equipment to indicate potential discrepancies from human factors criteria.

t l 2.2.2 Methodology 1

i The interviews were based on a standard set of criteria selected from NUREG-0700.

Seventeen licensed operators were interviewed individually. Operators were interviewed individually in a room dedicated to operator interviews which provided privacy and freedom from distractions. Code numbers were assigned before the interview so that sources of information could be traced while ensuring anonymity. After gathering biographical data (i.e., number of years license was held at HCGS, prior related 1

7 t

I experience, exact duty position / title, etc.) from operators, they were read instructions for the interview. These included: a brief description of the general control room topics to be covered (e.g., Workspace, Anthropometrics, Displays, HVAC, etc.) and a general orientation regarding human factors concerns. Operators responded to a standard set of questions using their first-hand knowledge and experience of situations or equipment that provided potential for safety concerns or errors. Four operators were visited again, under the same interview conditions, in order to clarify some of their previous responses.

2.3 Back Panel 10C604 (RMS) Survey 2.3.1 Objective The purpose of this task was to evaluate the human factors aspects at a component level of Back Panel 10C604 (Radiation Monitoring System) to ensure conformance with accepted human engineering practices.

2.3.2 Methodology This survey was based on application of relevant criteria from Chapter 6 of NUREG-0700, using observation and measurement techniques to evaluate controls, displays, I anthropometrics, conventions, labels and location aids. A more complete description of the task plan structure appears in the HCGS Summary Report. All criteria relevant to the 10C604 Panel were evaluated. Results appear in Appendix B of this report.

I I C8: LED lamps appear to be off when they are actually on.

I Disposition: A correction is not planned for this HED. The LEDs are distinguish-able from directly in front of the panel.

E C9: Association of label / direction arrow to rotary control for timer is ambiguous.

I Disposition: This HED will be corrected. Additional markings clarifying timer function and application will be added in a visible location.

I C10: The size of the numeral indicating the power factor on recorders / meters (e.g.,

1-SD-RR4813) is too small to read.

Disposition: No correction is planned for this HED. Information provided by these instruments is available to the control room operator on the RM-11 computer display.

I C11: Nonessential manufacturer's labels are at the top of Bay 1 and Bay 3.

Disposition: This HED will be corrected. The manufacturer's labels will be I removed.

I C12: Chart recorder (1-SP-RR4870A) and digital displays (e.g.,1-SP-RI4858D) are below the recommended minimum height.

Disposition: No correction is planned for this HED. Auxiliary panels in the I primary operating area meet the 20 ftC criterion.

I Q2: Benchboard console exceeds the maximum recommended illumination level.

Disposition: This HED will be corrected. See HED T14 for disposition.

I Q3: High variation of illumination levels between benchboard and operator console workstations.

Disposition: No correction is planned for this HED. The luminance ratios are within guidelines set forth in Exhibit 6.1-23 of NUREG-0700.

t Q4: Insufficient illumination of monitor console area is provided by emergency lighting systems.

Disposition: No correction is planned for this HED. Emergency lighting provides sufficient illumination for the primary operator stations during a loss of power event, i.e.,10C650 and 10C651.

I QS: Battery powered emergency lighting system does not provide sufficient illumi-I.- nation to backboards of benchboard consoles.

Disposition: No correction is planned for this HED. The backboards of the benchboards do not house instrumentation and, therefore, do not require the same level of illumination.

I Emergency lighting systems do not provide sufficient illumination to auxiliary I Q6:

panels.

Disposition: No correction is planned for this HED. In accordance with I NUREG-0700 guideline 6.1.1.lb, information is provided to the operator in the primary operating area to eliminate the need for attending backpanels during critical operational sequences.

I B4. Review of Communications and Auditory Alarms R1: Periodic preventative maintenance tests on communication system components are either nonexistent or inadequate.

Disposition: No correction is planned for this HED. Normal frequent use of the PA system will ensure that the system remains functional. Telephone end radio communications systems are repaired as required.

I R2: Portable radios are not equipped for hands-free or hig{ noire operation.

I Disposition: A correction is not planned for this HED. The por:able radios used at Hope Creek are adequate for the tasks performed by equipment operators.

I R3: There is no plant wide network of headset jackr, for proJonged communication during maintenance and calibration.

Disposition: No correction is planned for this HED. Many areas where routine I maintenance is performed have systems equipped with headset jacks. For other maintenance areas, alternative means of communication are avallnble.

I R4: Written instructions and procedures for operating thh communication systems are either missing or inadequate, and training is minimal.

Disposition: This HED will be partially corrected. Detailed instructions for operation of plant PA system will be placed at each station. Plant personnel are I familiar with procedures for other methods of communication.

l R5: Radio and public address system gain control adjustments 'can make signals inaudible in certain places.

i Disposition: This HED will be corrected. The PA stations equipped with gain adjustments will be either modified or marked to preclude unauthorized operation. '

I R6: In plant background noise sometimes interferes with the use of PA loudspeakers, paging, headsets or portable radios.

Disposition: This HED will be corrected. Plant PA systems have been set 10 <

I decibels above ambient noise level. Where this is not possible, further study will determine appropriate solutions.

ll E ~

I

'O ,

- R7: Control room communication handsets and cords pose personnel safety problems.

I .,

~ Disposition: No correction is planned for this HED. Phone cord length is required to complete tasks at the console. Where phone cords lay on the floor (at end of console A and E), operators do not walk close enough to the boards to present a safety problem.

.g I' -

' R8: Control room communication headsets have inadequate jacks, are uncomfortable, and have poor storage provisions.

Disposition: No correction is planned for this HED. Headsets are generally I* stored with the maintenance equipment in the M&TE shop for use by maintenance personnel.

R-9: The radio system has some " dead spots" where transmission and reception are inadequate.

Disposition: No correction is planned for this HED. PSE&G is planning to I perform a Hope Creek radio coverage survey in 1987 which will identify any dead spots in the plant and will implement corrective actions where necessary.

'1 R10: Use of communication equipment is difficult through protective breathing masks.

h a

Disposition: This HED will be corrected. Throat microphones will be added to the emergency equipment available to CR operators to enhance communications.

I R11: Same tiles on the Auditory Arnunciator Alarms for panels C and D, the Fire Alarm, and the Radiation Monitoring System Alarm give a high percentage of false alarms.

i Disposition: A program is in place to correct this HED. (HED T25 is related to this HED). A program to track alarm frequency and duty cycle in order to identify nuisance alarras has been undertaken. Nuisance alarms will be prioritized and corrected as 'necessary. Completion of this program will be dependent upon the number and type of deficiencies identified.

til g R12: The Air Control Monitor Alarm does not have a separate auditory signal system test capability; therefore, it is difficult to test this alarm.

I Disposition No correction is planned for this HED. Established surveillance cycles dictate the maximum period between testing.

I i u

I R13: Auditory Annunciator Alarms over control boards A-E are difficult to localize.

I Disposition: PSE&G will study this to see how best to modify the annunciator alarms to ensure aural distinctions between panels. The solution will be applied to the simulator. (HED T23 is related to this HED).

E R14: Hydrogen Recombiner A and B alarms exceed the maximum recommended level.

Disposition: This HED has been corrected. During performance of hot loss of power test, the Recombiner alarms were identified to be excessively loud. As a result, the volume of the alarms was readjusted to an acceptable level.

R15: Some auditory alarms cannot be heard in all parts of the control room.

Disposition: No correction is planned for this HED. The Radiation Monitoring and Fire Protection System alarms are retransmitted to the main control room I. vertical board annunciator where they provide a second alarm to the operator.

Personnel are always present in the primary operating area to hear incoming alarms. CRT displays identify specific information for identified alarms.

I R16: The Radiation Alert Alarm and the Evacuation Alarm are broadcast through the public address system.

I Disposition: No correction is planned for this HED. Channel 5 of the PA system provides plant communications with the main control room during PA system alarm transmissions. The cited alarms need to be broadcast to all plant personnel and the PA system is the only means to do that.

B6. Review of Operating Personnel TI: It is difficult to view displays / controls located on the lower part of the 10C650 panel from the 10C651 console - they are hidden from view.

Disposition: A correction is not planned for this HED. Overhead annunciators alert operator of abnormalities controlled and indicated on 10C650. The key instrumentation is visible from inner horseshoe.

I T2: Sometimes excess people block view of controls and displays in primary operating I areas.

Disposition: A correction is not planned for this HED. This situation is not typical and is caused by a unique situation (testing). The shift supervisor may direct extra personnel to leave the CR.

l T3: Direct access from inner (10C651) to outer (10C650) panels (and vice versa) is delayed by layout and design of horseshoe configuration.

Disposition: A correction is not planned for this HED. Hope Creek is designed to provide automatic accident mitigation without operator assistance for the first 10 minutes. Also there are enough people available to have an operator at the 10C650 and 10C651 panels.

I T4: It is difficult to clearly read the details of displays on outer panel (10C650) when working at 10C651 (console).

Disposition: A correction is not planned for the HED. There is no design basis to read the 10C650 instrumentation from the 10C651. It is intended for displays to be read from in front of the respective panels.

T5: There is limited working space at "B" (feed pump controls) and "D" (main turbine controls) panels when two people are required to work there simultaneously.

Disposition: A correction is not planned for this HED. Only one person is required to perform tasks at the "B" and "D" panels. The training includes only one operator.

I I

D-11

1 I.

T6: Phones located on inner horseshoe panel are located very low (18" from floor) and require operator to bend down to push phone talk button while monitoring displays located much higher.

Disposition: This HED will be corrected. The PA stations located on the back of the 10C651 panel will be modified to incorporate the page button on the I receiver.

T7: Short phone cords located on the back of the inner horseshoe prevent operator from getting close enough to read displays clearly while talking on the phone.

Disposition: This HED will be corrected. The cord lengths will be increased during receiver replacement outlined in HED T6.

~

I

- T8: Insufficient limits on movement of nonessential but authorized personnel in I computer room to work on CRIDS occasionally results in downtime of CRIDS for periods of time.

I Disposition: A correction is not planned for this HED. Current procedures require that shift supervisor give permission for personnel to work on CRIDS.

I T9: CRIDs CRT display is so high that, when viewing it from 10C651 panel or from between 10C650 and 10C651 panels, operator must put head back in an awkward position. It is above normalline of sight when viewed from the latter position.

Disposition: A correction is not planned for this HED. CRT location meets NUREG-0700 (section 6.1.2.1 and 6.7.2.3) vertical line of site angle guidelines.

T10: Procedure manuals, P&lD/ flow diagrams and some other reference materials are not available or not conveniently located (in some cases, located outside the CR).

Disposition: A correction is not planned for this HED. Required documents are located to facilitate easy cecess by the primary user. Any additional

. documentation is available in the technical document room.

I T11: The center (10C649) desk is covered with a phone setting in the center, leaving i limited room for using required materials / references.

Disposition: This HED has been corrected. Adequate space is provided by the recent addition of table in front of 10C649 panel.

lI 1

B-12

I T12: Because there is no carpeting in the primary operating area of the CR, operators indicate knee and foot fatigue resulting from standing and moving on hard floor surface for long periods of time especially when overtime is worked.

I Disposition: A correction is not planned for this HED. Chairs and stools are available for operators.

I T13: Eight inch wide lockers do not provide enough storage room for all uniforms, jackets and other work related files.

Disposition: A correction is not planned for this HED. Lunch box and coat storage room is available in the ready room adjacent to the CR.

I T14: Glare (which occurs when CR lights are very bright) delays operator's efforts to read labels and to determine if pushbutton bulbs are on or off.

Disposition: This HED will be corrected. A lighting level range will be established for the primary operating area.

T15: There is difficulty in distinguishing high from low priority color tiles when overhead lights are too bright.

, Disposition: A correction is not planned for this HED. As a result of an earlier HED, a red triangular marker has been placed in the corner of red tiles to distinguish them from lower priority tiles (amber and white).

I T16: Pull out shelves on 10C651 panel near reactor controls ~are not sturdy when extended for use as table surface.

Disposition: This HED will be corrected. A work order will be written to restore the extensions to original condition.

T17:

I There is no kitchen available to operators. Alternate eating facility is cafeteria which is far from CR.

order to prepare his food.

This situation requires operator to be relieved in Disposition: A correction is not planned for this HED. There is a microwave and refrigerator in the ready room. Sinks are nearby.

I I m13

I T18: Sometimes crowded restroom delays operators in returning to CR.

~

Disposition: No correction is planned for this HED. Reduction of construction activities has eliminated the problem.

I~ T19: The HPCI/RCIC controls are located on the 10C650 B panel while the related indicators / displays are located on the outer C panel in a position that is not easily readable poor angle and distance from controls.

Disposition: A correction is not planned for this HED. Suppression pool I temperature does not require constant monitoring. Technical specifications require monitoring once every 5 minutes during certain tasks (testing of HPCI/

RCIC).

I T20: When CR ventilation is in Recire Mode, noise level intensifies and adds to I distraction for operators. The condition interferes with effective aural communi-cation.

Disposition: No correction is planned for this HED. The Control Room I Emergency Filtration System (CREFS) is only in operation under emergency conditions.

I T21: When there is an excess of people working in CR (e.g., sync of turbine generator I, or other procedure), it can sometimes be distracting for operators. Aural communication and tasks dependent upon aural cues become difficult.

Disposition: A correction for this HED is not planned. The senior shift I supervisor maintains administrative control over personnel and activities in the CR.

I The "A" T22: Chiller located above the control room is excessively noisy when in I operation. The noise distracts from operator aural concentration and decreases ability to be alert for oral communications and other aural cues.

g Disposition: A correction is not planned for this HED. The chillers are g excessively noisy only when operating unloaded, which is an unusual and infre-quent alignment.

I em

T23: The alarms are not aurally distinguishable between annunciator panels. As a result, operator must check each panel to determine which panel has the alarm.

I Disposition: This HED will be corrected. PSE&G will stady this to see how best to modify the annunicator alarms to ensure distinctions between panels. The solution will be applied to the simulator. See HED R13.

I I T24: Control room noise is excessive when several alarms are going simultaneously and it becomes a:stracting for the operator to communicate with other operators.

Disposition: A correction for this HED is not planned. The operator has responsibility and ability to acknowledge and respond to all alarms.

I T25: Several nuisance alarms distract operator from recognizing a true warning situation (e.g., SACS; HVAC trouble; Station Service Water System; etc.).

Disposition: This HED is being corrected. A program is in progress to evaluate and thereby reduce nuisance alarms. See HED R11.

T26: Walkie talkie communication is difficult between CR and noisy, remote areas such as drywell.

Disposition: This HED is to be addressed with the radio communications survey. See HED R9 for disposition.

T27: Static and distortion make it difficult to get clear, strong message using walkie talkie when communicating between control room and remote areas.

Disposition: No correction is planned for this HED. PSE&G is planning to perform a Hope Creek radio coverage survey in 1987 which will identify any dead spots in the plant and implement corrective actions where necessary.

I T28: The two lockers across from the control room are not large enough to contain all I the tools that operators need to store there. As a result they are delayed when checking the needed tools out of other departments.

Disposition: No correction is planned for this HED. Tool lockers are provided for field operators.

l l D-15

T29: CR gets unnecessary paging communications from drywell area. The only line out of drywell is line 5 (also an emergency line). For that reason, line 5 automatically pages in CR. Though messages are not intended for CR, CR personnel hear them and it results in increased CR noise level. This additional noise distracts from alertness required for othe aural warning.

Disposition:

I This HED will be corrected. Detailed instructions for the operation of the plant PA system will be placed at each station. Paging calls from the drywell area will not be a problem during normal operation of the plant. _

T30: Operator reports that channel indicator on PA dial is loose. As a result, he must count clicks in order to reach desired line. This process can cause delay.

Disposition: A correction is not planned for this HED. There are procedures in place to identify and initiate repairs on equipment.

T31: Operator reported some occasions where there were 1 1/2 to 2 day delays in getting replacement bulbs for annunciators and pushbuttons. Delays were attributed to inadequate stocking.

Disposition: This HED has been corrected. The storeroom has obtained a sufficient supply of control room bulbs.

T32:

I Operator reported occasional delays in replacing bulbs for lack of replacement tools. Only 1 set of replacement tools were issued.

Disposition: A correction is not planned for this HED. As an administrative I procedure, it is policy to replace one bulb at a time, by one cperator, in order to avoid replacing the wrong cover. Only one set of tools is provided.

I T33: Operator reports that RZ bulbs GE 387,328 and S382, which are used on the main panel, all look alike. They have different intensities, however, and are stored in a I drawer labeled 387. Operator can easily confuse bulbs.

Disposition: This HED will be corrected. Proper replacement bulbs will be specified to the operators for all 10C650 and 10C651 equipment.

I I

I I "e

I T34: Operator has observed I&C personnel experiencing difficulty in replacing recorder paper. Paper wraps around spool, gets stuck and stops. Take up roller then must be rolled manually. The lip of the recorder door can catch on spool and cause I .

problems mentioned above.

Disposition: A correction is not planned for this HED. There is an I&C person on all shifts to respond to any recorder paper replacement problems.

T35: When an operator receives an incoming alarm, he has difficulty identifyng the blinking tile because of the slow annunciator flash rate. The operator may miss the flash in scanning the annunciator tiles.

Disposition: This HED will be corrected. Annunciator system will be modified to provide a faster flash rate.

T36: CR does not have a first out panel for the reactor trip or turbine trip. Though I CRIDS sequence of events is available .for reactor trip first out information, it does not display which of the 8 reactor levels is associated with the trip.

Operator is delayed in determining what condition tripped reactor or turbine and I is further delayed in selecting appropriate procedure.

Disposition: A correction is not planned for this HED. There is a symptom I oriented EOP which eliminates need for knowing exact cause of scram. Post trip review procedure is provided to determine the course of action.

I T37: Operator suggested that there is information available through computer system that he doesn't know how to access.

I Disposition: A correction is not planned for this HED. A CRIDS Users Manual is available within the Hope Creek document control system T38: Many annunciator horns are loud and irritating. They detract from operator's concentration and ability to detect other aural cues.

Disposition: A correction is not planned for this HED. See HEDs T24 for I disposition.

I T39: Operator indicated that audible alarms can be defeated by turning down the audible part of alarm, which is controlled behind the panel. Operator could miss audible cue if this is done.

Disposition: A correction is not planned for this HED. Adjustment of alarm volume is outside the scope of the CR operator's responsibilities.

B-17

I I T40: A lamp test control could not be located for the group of lamps in RHR - Loop C on panel 10C650. Operator might not realize that bulb has gone out. $

Disposition: A correction is not planned for this HED. PSE&G Engineering is aware of no cases where lamp tests cannot be performed on the RHR system in the main control room.

I T41: The relationship between lamp test pushbuttons and which lamps they test is Ie unclear, possibly resulting in a group of lamps not being tested.

Disposition: A correction is not planned for this HED. Lamp test pushbuttons I are located in the same vicinity as their associated bulbs.

I T42: Operator reports that there is no signal or indication that gives immediate notification that a bulb or annunciator (visual) is out of service because of flasher I or bulb problems. He could miss warnings or abnormal conditions developments as a result.

I Disposition: A correction is not planned for this HED. Administrative procedures require operator to check lamps once each shift. This lamp te t would reveal an out of service condition.

I T43: Operator reports that some alarms occur too late in development of an abnormal I situation for him to respond effectively. When the nonregenerative heat outlet temperature of the RWCU gets too high, the alarm goes off, for example. At that point, however, the system is already isolated and the pumps have tripped. Had I the alarm started earlier in the process (initiated by a lower temperature),

perhaps operatcr could have isolated part of the system instead of the whole system going down.

Disposition: A correction is not planned for this HED. Many plant alarms are designed to inform operators of an automatic system actuation, not necessarily designed to permit sufficient time to preclude the action.

T44: Annunciator tile has a large number of inputs.

Disposition: A correction is not planned for this HED. In order to eliminate an ,

excessive number of alarm tiles, Hope Creek design provides several alarms into a  ;

I single alarm window. Upon receiving an overhead alarm, operator must access computer for specific alarm or dispatch an operator to the equipment. j I

T45: The cord on the fixed based walkie talkie located behind the 10C649 desk is not very long. As a result, operators using the walkie talkie are forced to relay information to operator in the horseshoe area or to walk back and forth from I horseshoe area to fixed based walkie talkie. This causes delays in relaying remote operations information.

Disposition: A correction is not planned for this HED. Walkie talkie is adequately accessible from 10C649 desk.

I T46: Operator reports that there are many alarms that require CR operator to dispatch auxiliary operators to get information necessary for CR operator to understand the alarm. This causes delay in responding to the alarms.

Disposition: A correction is not planned for this HED. Practice is consistent with Hope Creek system design. See HED T44 for dhposition.

T47: No reflash on " rod out motion block". When one alarm on the " rod out motion block" annunciator window has been acknowledged and another alarm associated with that same window occurs, the tile window does not reflash.

I Disposition: Reflash capability will be reviewed and corrected as necessary, as part of the Nuisance Alarm Study outlined in the disposition to HED Ril.

T48: Operator is slow in receiving necessary information due to the location of the period meter and slow CRT.

Disposition: This HED will be corrected. See disposition of HED T110.

T49: Interlocks are set up so that when any 2 circulation water pumps are tripped within 3 minutes of each other, the 2 remaining pumps trip, causing MSIV to close.

This could result in a scram.

Disposition: A correction is not planned for this HED. The interlock system i performs as designed.

T50: Unnecessary interlock as it now exists, the secondary condensate pump trips on  ;

low flow signal.

Disposition: This HED has been corrected by resolving the minimum flow valve problem.

i I  !

i B-19

I T51: Mode switch and reactor Feed Pump controls have neither guards nor covers to prevent inadvertent actuation.

Disposition: A correction is not planned for this HED. Many important controls are provided with mechanisms to prevent inadvertent actuation (e.g., Key and rotary position required to actuate). Mode switch does, in fact, require keyed actuation.

T52: Operator reported that pushbuttons for " control rod drive system" provide too much resistance.

Disposition: A correction is not planned for this HED. These pushbuttons require additional resistance for their function and are not associated with probability of error.

I T53: The controls for the secondary condensate feed pumps / valves are sequenced in such a way that an operator could easily confuse and inadvertently operate the wrong control. The component arrangement is contrary to what operator would normally expect, given panel layout of primary condensate pumps. Operator I reported a case where he almost inadvertently activated the secondary B oil pump while attempting to operate the secondary A pump.

I Disposition: This HED will be corrected. Secondary condensate pump compo-nent locations will be modified to be similar to primary condensate pump configuration.

I T54: When the shutdown cooling isolation valves (Panel A 10C650) are operated out of I sequence, the result could be drLining of the reactor vessel. An interlock could prevent this.

Disposition: A correction is not planned for this HED. System operating procedures provide proper sequencing for cp tration of these valves. This prevents inadvertent draining of reactor vessel.

I Excessive interlocks on SRV takes away operator's control.

I TSS: Operator had to manually open an SRV to reduce / relieve pressure when HPCI would have provided more control.

Disposition: A correction is not planned for this HED. Interlocks ensure I systems operate within designed limits.

I I

I e.

T56: Steam Jet air ejector and the feedwater heater inlet / outlet valves can be activated out of sequence. No device is provided to prevent their nonsequential activation.

Disposition: A correction is not planned for this HED. Operation of these valves is controlled by system operating procedures.

I T57: The Fire Protection and Radiation Systems are located outside the horseshoe arca and require operator's cbservation at the same time operator is required to monitor components in horseshoe.

Disposition: A correction is not planned for this HED. Terminal dispitys for these systems are available in the primary operating area.

I T58: Operator reports that feedwater heater controls do not need to be located in the I CR. They are used only 1/2 day during start up. All other times, there is nothing to monitor. These controls are used infrequently.

Disposition:

I A correction is not planned for this HED. These components are required to be located in the CR.

I T59: Operator reports that he sees no reason to have key control of HPCI/RCIC isolation Signal Reset. The initiation signal must be cleared before it is reset.

Disposition: A correction is not planned for this HED. They key is provided to force the operator to strongly consider reset of system isolation before doing so.

T60: Operator reports that the Turbine Building Chiller control on Panel E provides the operator with nothing to control. He concludes it is unnecessarily located in CR.

He adds that it is not used frequently.

I Disposition: A correction is not planned for this HED. There may be times when the operator might need to use this control (start /stop) to maintain normal operating conditions.

I T61: Operator reports that the phase angle volt meter on the 10C650 panel is never i

used and is therefore not necessary for operator tasks.

Disposition: A correction is not planned for this HED. The Main Generator Phase Voltage Indicator provides useful information.

B-21 l

1I

E T62: Operator reports that the Reactor Building and the Drywell Sump indicators are never used except to notify Rad waste personnel. Therefore, they needn't be located in the horseshoe.

I Disposition: A correction is not planned for this HED. These indicators are used in execution of Reactor Building Control EOP.

l I T63: Operator stated that Reactor Deluge Isolation valves do not need to be located in the primary operating area.

Disposition: A correction is not planned for this HED. This valve provides the I operator with the ability to perform isolation of the fire water line into the l

reactor building.

1 I

f T64: Operator comments that Service Air System Compressor Control (KA) does not

need to be located in the CR. He explains that after operator turns the system i on, everything else about it is automatic.

l f Disposition: A correction is not planned for this HED. This control provides the operator with the ability to start an additional service air compressor when the operating service air compressor malfunctions.

I T65: The fire protection computer terminal and fire panel present operators with information to which their only response is to report it to site protection

!I personnel.

Disposition: No correction is planned for this HED. Main control room lI operators need to be aware of fire locations to determine equipment availability.

I

'u T66: With the Cutler - Hammer and Bailey pushbuttons, it is difficult to discriminate between pumps and valves. Operator reported that RHR-A pump was judged to be running when it was not. He had confused an adjacent open valve with the I nonrunmng pump.

Disposition: A correction is not planned for this HED. Operators are expected I to read instrument identification numbers and make distinctions based on that.

T67: Operator reported that none of the RZ controllers have stops that would keep him from overshooting a desired parameter.

Disposition: A correction is not planned for this HED. System Operating procedures provide the operators with guidance to control plant parameters.

I

'I em

I T68: Operator reports that startup level controls of the Feedwater Systems (B sec, panel 10C651) do not allow fine tuning control. As a result, operator cannot get a gradual opening of valves; he gets too much or not enough water to the reactor.

Disposition: This HED was partially corrected by the addition of a module to the circuit. Also, circuitry will be fine tuned during power ascension program, which is in progress.

T69: Operator reports difficulty in determining whether RZ pushbuttons are on or off under normal ambient lighting conditions, especially when only one bulb of Bailey pushbuttons is working.

Disposition: The operator will have identified any burned out bulbs during the lamp test that is performed at least once per shift. Adjustment of the control room lighting levels will provide additional lamp distinguishability T70: The Scram Discharge volume rotary control rotates into 2 positions which are non-functional. Those 2 positions are unmarked and unlabeled.

Disposition: This HED has been corrected. All positions are now labeled.

I T7h Operator reports that there is delayed stroke confirmation. He must hold control in position 10-15 seconds after "close" light appears in order to ensure valve is I fully closed. This is true for Circulating Water Discharge Valves, RHR Valves HVF010A&B and HVF024A&B.

Disposition: This HED was corrected in March 1986. Operations Department I will be inicrmed of correction and that it is no longer necessary to hold pushbuttons.

I T72: Main Steam Stop Valve control is delayed in indicating activation and is not identified that way. As a result, an operator could judge the valve to be broken I when it is just slow to indicate.

Disposition: A correction is not planned for this HED. There is a positive I indication of valve "open"/" closed" status at all times.

I I

I I a-22

l T73: Operator reports that when going from "on" to " bypass" on the Condensate System, Steam Packing Ext Bypass Valve, both lights go out for 2 to 3 seconds rather than both light going on. Operator gets confusing feedback and could assume neither "on" nor " bypass" is working.

Disposition: This HED will be corrected. Pushbutton descriptions will be I changed to read " Bypass VLV PDV1719 open" and " Bypass PDV 1719 auto".

Though "open" light does not appear immediately, indication of actuation can be confirmed via CRIDS display.

I T74: When certain controls are activated to change equipment status (e.g., throttling a I CRD valve - RPS solenoid (10C651 panel, See C), Redundant Reactivity Control System, Turbine (Main Bypass Valve) the lighted indicator goes out. No light is present to indicate valve position during valve travel. This is inconsistent with convention.

Disposition: A correction is not planned for this HED. Generally Hope Creek I control room design does give positive indication by illumination. There are some cases where this is impractical to do so. (e.g., power available LEDs on indicators and recorders and Reactor Protection System power available).

I T75: In the MSIV System, the meter scale is not sufficiently wide to show necessary range.

Disposition: A correction is not planned for this HED. MSIV Seal Systems I pressure is designed to be used during operation of the sealing system. During normal plant operation, other indicators are available.

I T76: Many scales on horseshoe panels do not fail offseale.

l Disposition: A correction is not planned for this HED. A red LED light, which r

is on during normal operating conditions, goes off when there is a loss of power to the meter.

II

, T77: Operator reports that the Control Rod Drive Mechanism Temperature Recorder I

and the Reactor Vessel Metal Temperature Recorder are located outside the primary operating area in a remote (field) location, but should be in the CR.

Disposition: This HED will be corrected. Reactor Vessel Metal Temperature i will be transmitted into control room via CRIDS. A correction is not planned for l the CRD Mechanism Temperature Recorder.

T78: Operators have difficulty reading displayed information on recorders because of

[ glare, angle, unclear glass windows, and position of recorder pens.

Disposition: This HED will be partially corrected. Glare will be addressed with HED T14. Windows with unclear glass will be replaced if required. Current L information is displayed by the ribbon indicators.

F 1

T79: Operator reported that some zone codes are inaccurate; they do not accurately reflect nor indicate the desired operating range.

Disposition: This HED will be corrected. Present zone markings are con-sidered temporary because their ranges are in the process of being verified on an on going basis.

L T8o: operator reported that some recorder readings are difficult to read because the print details are so small that they cannot be read from inner horseshoe.

I Disposition: A correction is not planned for this HED. HED T4 is related to L this HED. There is no design basis to read the 10C650 instrumentation from the 10C651 panel; displays are to be read from in front of their respective panels.

T81: Some CRIDS parameters have more precision than required. In the case of

( temperature (79.87352. . . ), the additional digits can be confusing and are unnecessary.

Disposition: A correction is not planned for this HED. The additional precision

{ might prove to be useful in certain circumstances.

T82: The sequence of displays is not matched to the sequence of the controls in the IRM section. As a result, operator reports much delay and confusion related to ensuring that the intended control is affecting the desired display.

Disposition: This HED will be corrected prior to startup following the first refueling outage.

T83: Labels on " deice" controls for cooling tower express the opposite action intended by their actuation. The " deice" function is indicated by "close".

{ Disposition: This HED will be corrected. A descriptive name plate will be added to clarify the function of the "open" and "close" positions.

B-25 C - - - - - - - - - - - -

T84: Jockey pump scales RHR A&B, HPCI, and RCIC have different ranges, making it difficult to quickly and accurately compare discharge pressures.

Disposition: This HED has been corrected by the addition of zone markings.

I T85: Hotwell level Indicator scale provides too much range.

I Disposition: A correction is not planned for this HED. The present range provides valuable information that may be used during a transient situation.

I i

T86: Arrows on Feedwater Recire Flow Control do not accurately represent function.

Disposition: This HED will be corrected prior to startup following the first refueling outage.

1 I

l T87: " Remote" label on 500 KV Circuit Switch is used incorrectly; it is inconsistent with the meaning of other " remote" labels.

Disposition: A correction is not required because system operation is not as described in the HED (electricallogic E 3010).

I i

I j

T88: Adjacent Post Accident Monitoring System recorders have inconsistent use of colors; one recorder uses red to represent reactor level parameter while the adjacent recorder uses red to represent pressure.

Disposition: A correction is not planned for this HED. There are not enough colors available to establish a color code for each parameter.

I T89: Computer printers stop printing when paper is misfed.

Disposition: A correction is not planned for this HED. A backup printer is available.

I T90: The Alarm Response procedure provides responses only for points which input into overhead annunciator. This results in wasted time when operator must use the I response manual for non overhead points in the alarm.

Disposition: This HED will be corrected. Alarm responses will be developed I for these computer points and will be provided to operators as they are developed.

I I -

l I ,

T91: Some horseshoe CRT parameter displays have long, (1-30 second) update times compared to the 10C649 CRT readings, resulting in conflicting information.

Disposition: Engineering has previously analyzed the concern and is aware of a possible 1-15 second response time delay depending upon the point source.

Engineering is evaluating the alternative and presently taking appropriate action to reduce the response time.

T92: Occasionally CRT display fades from screen and information cannot be retrieved from affected screen.

Disposition: This is a component malfunction. Procedures are in place to initiate corrective actions for problems of this nature.

I T93: Priority coding of high priority messages does not appear on the printout; in addition, the operator must leave the horseshoe to obtain the printout.

Disposition: A correction is not planned for this HED. Alarm messages are I always sent to chronolog and are also displayed on the top of the screen, provided the incoming alarm rate is less than or equal to 3 messages /6 see period. If this rate is achieved or exceeded, an " alarms to chronolog" message will be displayed on the CRT. Under this condition, alarm message will not be displayed on the I CRT but still sent to chronolog. The operator may then view incoming alarms directly from chronolog on any CRT.

I T94: Vague value indications for the Service Water System pump on the CRT are verbal (e.g., "not high") rather than numerical, and do not indicate to the operator I if these values are approaching an abnormal range. .

Disposition: A correction is not planned for this HED. The CRT is not the sole I source of information. The operator uses the CRT as a tool to determine appropriate course of action. Alarms are generally designed to provide an operating margin prior to entering a critical range.

I T95: Some of the keys " stick" on the computer mini keypads located on the inner I horseshoe.

Disposition: A correction is not planned for this HED. Component and equipment malfunctions are corrected via normal plant maintenance procedures.

I T96: CRT response time, even for simple status information, is longer than the maximum recommended time of two seconds.

Disposition: Engineering has previously analyzed the concern and is aware of a possible 1-15 second response time delay depending upon the point source.

Engineering is evaluating the alternatives and is presently taking appropriate action to reduce the response time. See HED T91 and T100.

T97: Incorrect setpoints in the Service Water System and Cire Water System generate false urgent messages on the CRT.

Disposition: This HED will be corrected. The setpoints identified above will be reviewed and corrected as necessary.

I T98: There is some confusion on the meaning of the Main Generator Potential Transformer Voltage overhead annunciator tile.

Disposition: No correction is planned for this HED. The alarm response procedure provides origin of alarm points.

I I T99: Some Annunciator Response Manual instructions are not helpful and waste time.

For example, the manual indicates "no action" for Panel Rooms, Chilled Water A/B Trouble.

Disposition: This HED will be corrected. The Alarm Response Manual will be reviewed for the above items and corrected as necessary. Administrative procedures are in place that provide steps necessary for revision cf existing I procedures.

I T100: Computer CRT screen " freezes", making updating and display changes impossible.

Disposition: Er.gineering has previously analyzed the concern and is aware of a I possible time delay depending on the point source. Engineering is evaluating the alternatives and ~is presently taking appropriate action to reduce the response time. See HED T91 and T96.

I I T101: CRIDS does not display key parameters on the CRT such as Diesel Generator Engine Status and RWCU System.

Disposition: No correction is planned for this HED. Hardwired instru-I mentation for the above parameters is available in the main control room. CRIDS provides adequate information where hardwired instrumentation is not available for evolutions performed from the control room.

I B-28

I I T102: There is a delay in feedback of Generator Terminal Voltage adjustments which may result in a tripped generator.

Disposition: No correction is planned for this HED. The pre operational and power ascension test programs determine acceptable control circuit tuning.

I T103: Operator must step through many displays before reaching desired screen displays.

Disposition: No correction is planned for this HED. Critical parameters can be viewed through the SPDS displays. All other displays are directly selectable through menus.

I T104: Annunciator Response Process requires the extra step of operator leaving the CRT to go to the Annunciator Response Manual; this step may be unnecessary.

Disposition: No correction is planned for this HED. Placing Alarm Response I procedures on the CRT would be cumbersome and clutter the display of dynamic information.

I T105: Inaccurate demand information on controller during manual mode.

Disposition: This HED has been corrected. An additional indicator has been provided for the Reactor Recire Manual / Auto Station output.

I T106: Non-linear scale on Core Spray Flow Indicator is more difficult to read than the linear scale which was previously used.

Disposition: A correction is not planned for this HED. Non-linear scales provide degree of precision necessary for conduct of related tasks.

I T107: Delay in response of indicator light causes potential misreading of flow indication.

Disposition: A correction is not planned for this HED. Analog flow indication I is provided for RHR, HPCI, and RCIC flows.

T108: Position of arrows on multi scale RY meters may cause confusion.

Disposition: This HED has been corrected. As a result of an earlier HED, a space has been provided between the graduation scales for scale distinguishability.

lI l T110: Period meter is located too far from reactor control bench.

l Disposition: This HED will be corrected. Period indication will be provided on the 10C651 panel in the Rod Select Module area.

Till: Period meter is difficult to read.

, Disposition: This HED will be corrected. See disposition for HED T110.

f T112: Digital readout on panel 10C604 is difficult to interpret.

Disposition: A correction is not planned for this HED. The RM-11 provides I trend capability and single point readout. The operators have received additional training on the operation of the 10C604 panel and RM-11 interface unit subsequent to identification of this HED.

I T113: SACS pump controls and related displays are located too far apart.

Disposition: A correction is not planned fcr this HED. The operator can view SACS parameters on CRIDS while stationed at the 10C651 panel.

I T114: Suppression Chamber Spray meter is loceted too far apart from related controls.

Disposition: A correction is not planned for this HED. The instrumentation identified is only used during accident conditions and not performed in time critical tasks.

T115: Related SRV controls and displays are located too far apart.

Disposition: A correction is not planned for this HED. Operators have I adequate time to confirm SRV control action.

I I 1 l o-30

I T116: Reactor Vessel Pressure Indicator level display on CRT is imprecise.

Disposition: The HED will be corrected. A work order will be written to I correct the discrepancy.

I T117: Related full core controls and displays are located too far apart.

Disposition: A correction is not planned for this HED. The full core display is I designed so the operator can distinguish rod patterns from in front of panel 10C651.

I T118: Some SACS components are located outside the SACS demarcation lines in the RACS section.

Disposition: This HED will be corrected. The portion of mimic strip separat-ing the TACS isolation valves from the rest of the SACS controls will be removed.

T119: Jockey pump controls are difficult to locate.

Disposition: No correction is planned for this HED. The pumps are normally running and alarms are provided for loss of keep fill.

I T120: Lack of RCIC functions at Remote Shutdown Panel (RSP).

Disposition: A correction is not planned for this HED. RCIC instrumentation I on the RSP is sufficient to perform its intended function of reactor water level control. Cited additions are not required for this control.

I T121: RPV Level range too small.

Disposition: This HED will be corrected. Additional reactor water level indication will be provided on the Remote Shutdown Panel.

I T122: Lack of table space at Remote Shutdown Panel.

Disposition: A correction is not planned for this HED. The Remote Shutdown Panel, when occupied, will have at least one operator to hold necessary documents while other operator (s) perform tasks.
