1.0 INTRODUCTION
The work' described in this report is in support of the Boston Edison Company (BECo) Detailed Control Room Design Review - (DCRDR) , Phase 1 efforts, for the Pilgrim Station Control Room. The DCRDR Surface Enhancements, Phase 1, are being done by Management Analysis Company (MAC) . MAC has designed the Surface Enhancements and installed the labels, mimics and demarcation on the panel in the simulator and in the main control room.
1.1 BACKGROUND
The Augmented Off-Gas System Panel, CP-600, houses the instrumentation that is used to control Trains A and B of the Augmented Off-Gas System. It has been inluse since 1972. It contains the controls and instrumentation for the operator to operate the following support subsystems for the removal of radioactivity from the 2ir ejector exhaust to the main stack.
o Steam (to the Steam Jet Compressor) o Service Air (to the Steam Jet Compressor) o Main Condensate (to the AOG Condenser) o Refrigeration Units (to the Cooler Condenser) o Hydrogen Monitoring The control panel is located in the control room.
1.2 OPERATOR PERFORMANCE Control panels are the tools used to control the plant.
i Their quality, like any other tool, has a direct impact on how the plant is controlled. The operator's performance capabilities are the resu?t of a variety of influences including:
- 1. The operator himself
- 2. Conditions under which he is ope'.ating
- 3. Design of the equipment and information delivery l 4. Procedures
- 5. Training l
)
l l
The ability to initiate and successfully complete the i tasks is heavily influenced by the manner and type of !
information displayed to the operator. ;
i TP . labels and demarcation designed for the Augmented Off-Gas Panel will result in a significant decrease in j the. operator's perceptual and interpretational j requirements when lining up or otherwise using tne 1 system. This will reduce errors associated with the equipment and reduce the time it takes to do the right things. The enhancements address these problems in two ways:
- 1. Human Factors engineering design based on the recommendations of NUREG-0700, Section 6.
- 2. Performance Baced Enhancements -
the conscious placement of location aids and other equipment, to provide means to see the various systems and subsystems.
The Performance Based Enhancements utilize several techniques to enhance the operator's capabilities by:
- 1. Providing information on the panel that relates to the system, even in cases where there are no control components.
- 2. Addressing error reduction by:
o Providing a more complete cognitive model of the system and subsystem interactions, o Providing input at a higher cognitive level.
- It is easier to observe that something.
unusual has happened. (Component dependency is easier to see.)
- A small change will be more noticeable, making the operator aware of a change sooner, as well as making it easier to interpret.
- Reduce response time. (The time to figure j out what has happened has been reduced.)

,~2.0- ' CONTROL' ROOM DESIGN REVIEW
~
During the DCRDR/ activities, a human factors evaluation.
was performed and operators were interviewed 'to 'determine the . quality of the control- panel design. It was determined.that several' things could be done to' enhance the operator's performance capability. .In general these -
L are:
p
- 1. Provide a means to easily identify the components.
- 2. Provide a hierarchical label'. system.
- 3. Mount the labels in the proper location.
- 4. Assure the meter / recorder scales are easy to read-and understand.
The problems solved by the Surface Enhancements are:
- 1. - Reduced response time.
- 2. ' Reduced probability of error in selection.
- 3. Reduced probability of error.in. actuation.
.2.1. HUMAN ENGINEERING DISCREPANCIES Specific' problems were noted and recorded-as HEDs. The HEDs discussed in this report were transmitted to the NRC l
in the DCRDR Executive Summary Report,.Rev. 0'of July L 3984. The HEDs that deal specifically with the Augmented -
Off-Gas Panel, CP-600, are:
B_ED -Description 8A006 Enhancement Recognition and Identification:-
L The CP-600 Panel lacks operator . enhancement I
aids.
8A007 Logical Arrangement and Layout (other expectations) - CP-600 is not arranged for sequential operations.
! 4B060 General Principlas (economy) -
Controls. not used or connected- kaylock switch, inventory I item #512.
5B061 Usability of Displayed Values (elimination of operator conversion) -
The Adsorber Train differential pressure meter requires the operator to multiply the scale reading by 5 to determine the differential pressure.
1
HED Description 5B111 Visual Displays (zone markings) - The majority
.of instruments have no zone markings.
6B072 Labels and Location Aids (need icr labeling) -
Labels for inventory items No. 465 and 466 are missing. Temperature monitor and multipoint.
recorder.
6B073 Hierarchical Labeling -
The limited hierarchical labeling does not adequately satisfy the labeling criteria.
I h 6B074 Label Placement - Labels are not placed above their associated controls.
6B075 Label Placement - Labels are placed below their associated instruments.
6B076 Label Consistency - Internal consistency and ,
consistency with procedures. No standard list of abbreviations or acronyms is used.
6B077 Label Brevity - The use of abbreviations and I words is inconsistent.
6B080 Label Readability - Character heights are inconsistent.
6B081 Label Readability -
The labels are white letters on black background. The ~ contrast should be dark letters on light background.
6B084 Demarcation (performance) - Stick-on tape is used for most of the demarcation lines. '
6B085 Labels and Location Aids (color) - Color is not associated with specific functions.
8B100 Enhancement Recognition and Identification -
There are no distinctive enhancements for emergency controls.
1C005 Label Shadowing - Labels below instruments on vertical panels are shadowed. This is especially true for recorders that project beyond the panel surface.

5-2.2 ' ENHANCEMENT PROGRAM The Control Panel'HEDs fall into.several. groups:
- 1. Panel Enhancements and Minor Modifications
- 2. . Minor Relocations l-l 3. Removal of Abandoned Equipment
- 4. Switch Enhancements
- 5. Switch Modifications
! 6. Hardware Type ~
h
- 7. Equipment Location A . Surface Enhancement Program has been ' developed to address all' control panel HEDs. . It may not' resolve an equipment location ~ problem, but the potential for error is reduced:through the'use of location aids.
In August 1988 an Interim Enhancement program was ,
. implemented to get some enhancement into the control room -
as soon as possible,.and get operator input. This was being done without changing the content of any of the -
component labels. Changing the ' component labels will.
require .that these changes are . reflected in. the.
procedures. The work described in this report is for the interim enhancements.
The Surface Enhancement Program includes work in several areas. This report covers only the'.last three items.
The installation of the first three items is being.done by BECo.
o Meter scales o Removal of abandoned equipment o Installation'of shape-coded switch handles and new.
switch escutcheons o New hierarchical label system, including revised component labels and the addition of new system and subsystem labels o New or revised mimics in selected areas o Area type demarcation, using color patches to separate and group logical sets of controls and indicators

- 3.0' DESCRIPTION OF CONTROL PANELS AND ENHANCEMENTS-The Augmented O f f - G a s . P a n e l ,- CP-600, . has' had Surface Enhancements created to enhance the; operator's ability.
to respond during normal and' abnormal: situations..- The^
descriptions are generally of~the system and'how it is .
more understandable from' the enhanced . control . panei. .
There are also specific responses?to the'HEDs listed in Sect ion 2.1. The enhancements have.been prepared using a performance-based approach to assure.they address the operator's needs. They provide information derived'from the: ' operator discussions, EOPs, P& ids and. training.
materials.- .The information is displayed in Ja clear,
~. logical and ' operationally relevant manner. The techniques chosen to display the information were picked because, for that. situation,-they. reduce the probability for error. The panels now 'contain. more .useful
. information . than before, therefore they . will be more -
effective.and easier to use.
Figure.3.0-1 shows the-AOG Panel prior to any. surface.
enhancements. Figure 3.0-2 shows the panel after the enhancements have been applied.
3 .1 ' GENERAL-The Augmented Off-Gas Panel, CP-600, has been subdivided-to create perceptual groupings. 'Each_ grouping was analyzed to determine which location aid techniques could be used. - These were further evaluated to determine which technique.would result in the lowest expected operator error rate. The general groupings are:
- o. ' System Inlet o Preheaters o Recombiners o Off-Gas Condenser o Off-Gas Condenser-Cooling o Refrigeration o Adsorber vessels o Off-Gas Stack Isclation o Hydrogen Monitoring L

The analysis showed that to cm .plete the system (cognitive mode;l) additional cr.ponents. should be represented:
o Steam Jet Compressor o ' Water Separator o Cooler Condenser o Moisture separator o Points that the two trains come together and can be cross connected The Surface Enhancements can be. broken down into three general. categories.
o Demarcation (location aids) o Labels o Control Panel Layout The resolution of the HEDs in the general categories is described in the following sections. The resolutions.for specific HEDs are described in the text that discusses the work.done for that subsystem.
3.1.1 Demarcation Three HEDs listed in Section 2.1 deal with demarcation.
A description of their resolution follows:
HED Description of Improvement 6B084 The demarcation technique as well as the l materials have been changed. The demarcation I

ti The label scheme utilizes the hierarchical system described in NED Standard E-543, Nameplates and Labels.
The subsystem labels- were developed based on the functional categories used in the operator's training materials. All labels are placed above their associated equipment. The labels are fabricated in compliance with Specification E-543. .The abbreviations are consistent-
! with the BECo, NOD approved Procedure No. 1.3.4-2,. Word Useage.
The portion of these HEDs dealing with the Augmented Off-f Gas. Panel, CP-600, is resolved.
)
) 3.1.3 Control Panel Layout I
Three HEDs listed in Section 2.1 deal with control panel layout problems. A description of their recolution follows:
IED Description of Improvement 8A006 The Augmented Off-Gas System has had a great
& deal of system and subsystem information added 8A007 to the control panel. This information was added in the form of demarcation, labels and mimic diagrams. The Surface Enhancements have made the systems controls understandable.
These HEDs are resolved.
8B060 The keylock switch has not been abandoned. A label has been fabricated to tell the operator what it is used for. See Figures 3.13-1 &
3.13-2 Off-Gas Stack Isolation Selector Switch for before and after enhancements.
The portion of this HED dealing with the Augmented Off-Gas Panel, CP-600, is resolved.
3.2 SYSTEM INLET A source label has been added to show where the AOG process starts. The label is larger than other similar labels to make it more prominent. The wording was chosen to correspond to the accepted name STEAM JET AIR EJECTOR.
The AOG return is to the steam jet air ejectors at the OFF-GAS HOLD UP LINE.
,B' The steam jet air ejector exhaust to the AOG System has
'I had blue plexiglass mimic lines added. They flow from the source label through the Train A and B inlet isolation valves into new symbols to represent the Steam I Jet Compressors for Train A and B. Figure 3.2-1 shows the steam jet air ejector and steam inlet isolation valves control switches before the enhancements. Figure 3.2-2 shows the source labels, mimic and steam jet I compressors added to the panel.
A source label has been added to show that steam is used in the steam jet compressors. The label is the same size as the other source or continuation labels used on the panel. Red mimic lines connect the source label for I Train A with the inlet isolation valve and the steam jet compressor. The inlet isolation valve is used to control the steam pressure to the steam jet compressor. Both the valves and the steam pressure meters have been demarcated '
I l
the darkest shade to show this dependency. Figure l 3.2-3 shows the steam pressure meters before the ;
enhancements. Figure 3.2-4 shows the steam pressure meters after the enhancements have been added.
Mimic lines have been added for the compressed air supply to the steam jet compressors. They have been color coded I green. Separate source labels have not been added in order to de-emphasize the compressed air. The component label provides all of the required information and r arves I as the source label. This method meets the reau'.rements of a source label. Figure 3.2-5 shows the service air Figure 3.2-6 control valves before the enhancements.
I shows how the labels and mimics tie into the steam jet compressor for Train A.

3.3 PREHEATERS The process flow out of the steam jet compressors to the preheaters is represented by blue plexiglass mimic linos. The: blue' mimic lines are carried throughout the panel for the AOG process flow. Figure 3.3-1 shows the area where the blue mimic lines are to be installed. Figure 3.3-2 shows the area with the mimic and preheater demarcation. The preheaters are represented by a subsystem label within a demarcation color patch surrounding the preheater drain valve control switch. The demarcation is the medium shade to match the demarcation around the Train A and B inlet temperature meters. The preheater and demarcation can be seen in Figure 3.3-2 and the related meter and demarcation can be seen in Figure 3.3-3.. The difference in shade between the preheater inlet pressure and the recombiner temperature meter demarcation can also be seen. Figure 3.3-4 shows the meters before the demarcation. l 1 l )

3.4 RECOMBINERS The recombiners for each train are represented the same way as the preheaters. The blue process nimic line comes from the preheater to the recettbiner. It leaves the recombiner and flows into the Off-Gas Condenser. The demarcation used to represent the recombiner is the next to the lightest shade. It is the same shade as the demarcation on the recombiner inlet meters, as shown in y Figure 3. 3-3. Figure 3.4-1 shows the recombiner controls l before enhancements, and Figure 3.4-2 shows it after the I enhancements. i ) i i 1 1 I i i l

g > 3.6- OFF-GAS CONDENSER COOLING y The off-gas condensers are cooled. from :the condensate system. A yellow plexiglass mimic is used~to show the flow. It starts at a source label and splits, going into lL E the cooling water side of each AOG condenser. -The mimic lines show.the condensate flow' through _the respective - ~ l' train A or B isolation valve. Cooling water from.the h .g . Train B aOG then . ties into the common return via a continuation label. Ultimately the cooling-water: flows back to the' main condenser.- The isolation valve-to the. reactor feed pump suction has had the controls removed. Since the ' control switch is. still on the panel the' mimic represents this with a blind flange symbol. Figure 3.6-1:shows the control switches used to control the cooling water before the enhancements were applied. Figure 3.6-2'shows the entire cooling water system;to the, condensers. Figure.3.6-3 shows the Train A side' outlet
~
and'the: common return to the main condenser.

.a continuation label from the AOG condensers. The blue ;
mimic then runs to the water separator symbol and continues to the outlet isolation valve. After the , outlet isolation valve the mimic runs through the AOG delay line.

3'11; ADSORBER VESSELS: There are two sets of adsorber vessels. They can be used
. in series, :in parallel, or bypassed. Figure 3.11-1~ shows.
the control switches before enhancements. The mimic from the outlet.of the moisture separators runs. between the Adsorber vessels bypass valve and.the inlet-isolation valve indicating lights. It.then shows that;
. it can go in either direction as shown 'in Figure. 3.11-2.
A . single : label has been installed .over the control switches for the three valves that are used to shift the-Adsorbers from series to parallel.. In addition to the.
. usual label'information the label has been' engraved with the correct valve position indicated -for series or parallel. Figure 3.11-3 shows this before enhancements and Figure.3.11-4 shows it after.
An interlock from the AOG inlet' Process Radiation Monitor closes and. holds the Adsorber bypass valve .. shut,
' requiring the' process-flow to go:through-the Adsorber vessels. The. reset switch has been labeled to show its function, AOG INLET PRM BYPASS RELEASE, as shown in
~
Figure 3.11-2. The system discharge is shown by the blue; mimic line going from the adsorber bypass' valve to the termination label. The AOG system discharges just downstream ~of where it is slipstreamed out of the steam jet airejector-discharge.- A mimic line from the adsorber vessel control label also
^
goes to the termination label showing the flow: path 'out - of the vessels.

- 3 .12 - HYDROGEN MONITORING The hydrogen monitoring instrumentation has been demarcated to associate the alarm and monitoring by surrounding it with a color patch. The alarm and monitoring lights, and the. test and control switches are in separate areas.
The individual lights have been labeled to show channels A and B, as well as describe the alarm or caution. They also need to be revised to correspond to the expected . (approved) color scheme. l o Red - Alarm o Yellow - Caution, Hydrogen monitoring equipment problems o Blue - Status The Hydrogen Monitoring controls before the enhancements are shown in Figure 3.12-1. Figure 3.12-2 shows them after the enhancements.

L F 3.14 SWITCHES It has ' been recommended that the switch handles be changed to provide a standard coding. It-has not-been implemented, but will follow the criteria listed below: o Valve control switches - Change to oval handles if F the switch is an SBM or SB' type. This will provide l some consistency with the switches that are Type CR-2940. The GE Type CR-2940 switches are no longer available. All of the valve control switches should be ultimately changed to a CR-2940 or other approved heavy duty oil tight switch. If during future modifications an SBM or.SB switch is in a valve ! circuit being revised, the switch should be replaced i with a three position, spring return to center, heavy duty oil tight switch, o Selector switches - Change to " pointer". handles. o Motor control switches - Remain as " pistol grip" handles. 1 m_.- .-. .
