- HUMAN FACTORS GUIDELINES PUBLIC SERVICE ELECTRIC AND GAS INTRODUCTION Public Service Electric and Gas Company (PSE&G} has implemented an ongoing human factors program to review proposed design modifications.
In order to ensure a complete program, this document was developed to provide a human factors reference for all the various PSE&G organizations to work from. Section 1 contains the Salem standard list of abbreviations to be used for labeling.
Section 2 contains generic human factors design conventions that were extracted from NUREG-0700.
This section can be used to determine if a design modification is in conformance with NRC human factors criteria
- Section 3 contains Salem plant-specific human factors conventions that were either noted during the Detailed Control Room Design Review (DCRDR} or developed as a result of it. This section is especially helpful in determining if a design modification is consistent with existing Salem human factors conventions.
The use of this document in the development and review of plant modifications will ensure consistent application of human factors principles at Salem

1.1 Preface
- The intent of Section 1 of this document is to provide for standarization of word abbreviations at Salem Nuclear Generating Station. These two lists are to be used during the design process to determine the abbreviation to be used on the main control board labels, local panel labels, and annunciators.
- Abbreviations may be used when space does not permit use of the full length word.
- It is the intent that words not found in the abbreviations list are not to be abbreviated.
- The following abbreviations, as listed in Section 1 have more than one meaning. ABV AO ATT CAT ccw CP GW HP LO LOPA POT SP Above or Auxiliary Building Ventilation Automatic Operated or Analog Output Attachment or Attention Chemical Addition Tank or Cation Component Cooling Water or Counterclockwise Control Power, Control Point Generator Cooling Water or Gaseous Waste High Pressure or Health Physics Locked Open or Low Loss of Pressure Accident or Loss of Power Accident Potential or Potentiometer Speed or Spare If there is any possibility of confusion arising from the use of one of the abbreviations listed above, then the words should not be abreviated.

- HUMAN FACTORS GUIDELINES PUBLIC SERVICE ELECTRIC AND GAS SECTION 2. DESIGN CONVENTIONS CHECKLIST Human Factors Engineering addresses the efficient and safe operation of the control room from the operator's perspective.
When making design changes, it is important to consider how the changes will affect the operator in terms of the availability of necessary information, the adequacy of controls for the task performed, the efficiency of the overall panel layout, and the ity of the environment.
The human factors design conventions contained in this section are intended as guidance for the planning, development, and review of Salem design modifications.
By reviewing the applicable sections of these conventions, you can determine if the proposed design modification is in conformance with NRC human factors criteria (NUREG-0700).
Keep in mind that these are generic conventions and that the Salem plant-specific conventions and applications (see Section 3) that have already been established take precedence over the generic conventions.
Sect.ion 2.1 of the Design Conventions Checklist outlines human factors criteria related to panel layout. Controls and displays should be grouped in a way that reflects functional organization and minimizes operator movement.
For instance, components which belong to the same system should be located on the same panel, in an arrangement which indicates their relationship to each other. A series of controls which are used in sequence should be positioned in sequence on the control panel. Positioning controls where the operator can find them easily reduces the time required to perform a task and the chance of operator error. Section 2.2 discusses control-display integration, the association of controls and displays which are used together.
Important.
considerations include (1) ensuring that the operator can read a display while operating related controls, and (2) labeling controls and displays used in the same sequence of actions with the same alphabetic or numeric sequence.
Both Sections 2.1 and 2.2 contain many guidelines which apply to all control room design changes, regardless of the type of component affected.
22 HUMAN FACTORS GUIDELINES PUBLIC SERVICE ELECTRIC AND GAS Section 2.3 contains criteria specific to controls.
The operator should be able to perform a required function easily with the controls available.
Accidental activation of a control should be prevented.
The function of a control should be clearly identified, by color or shape coding, location, and labeling.
Careful selection and identification of controls is essential to smooth control room operation.
Guidelines on visual displays are included in Section 2.4. Displays should also be clearly identified and easy to locate. Scales should cover the full range of possible values and provide the degree of precision needed. Light indicators should be clearly on or off. The overall intention is to provide the operator with all the information he needs, without extraneous information which may distract or confuse him. Section 2*5 outlines criteria related to labels and location aids. A hierarchical labeling scheme, including labels for systems, subsystems, and individual panel elements, directs the operator quickly to the component he needs. Labels should be mounted securely and should not obscure other information.
Mimics can be used to integrate a group of controls into a system, making functional relationships clear to the operator.
Guidelines on annunciator systems are provided in Section 2.6. Annunciator warning systems, both visual and audible, should be discriminable and recognizable to operators.
Window legends should be legible and succinct1 annunciator response controls should be consistent in operation and placement to facilitate operators' response to alarms and subsequent remedial activities.
Section 2.7 contains criteria specific to the control room environment_.
such factors as lighting, sound, temperature and ventilation are important considerations.
An effort should be made to create a pleasant and comfortable work setting for the control room personnel.

- HUMAN FACTORS GUIDELINES PUBLIC SERVICE ELECTRIC AND GAS Table 2. Color-Banding Visual Displays Approach Indication will be evaluated for process limits in both the increasing and decreasing direction from the normal operating range where they exist. Associated digital setpoints for alarms and trips will be utilized to band the indicating ranges of visual devices where they exist. Criteria When indication is within the alarm limit(s}, the parameter is in the normal operating range and the color band will be green. When indication is between alarm and trip limit(s}, the parameter is out of the normal operating range and the color band will be yellow. When indication is beyond trip limit(s}, the parameter is in the abnormal operating range and the color band will be red. When indication is beyond alarm limit(s}, with no trip associated with the variables, the parameter is in the abnormal operating range requiring operator action and the color band will be red. When indication is not associated with alarms or trips of digital the ranges will be determined by system process calculations or equipment limitations.
Assumptions Any post-accident monitor will be color banded based on the normal plant operation and not on accident conditions.
Where no lower limits exist for the indicated variable, the green range will start at zero and end at the first upper limit. All colors may not be required for all indications

HED il identified clearances between the back of the console and the vertical panels that were 42-44" instead of the recommended 50". This difference of 6-8" may prevent an operator from backing up to read indicators that are located too high or too low on the vertical panel. This is no longer the case, because as stated on HEDs f6 and 113, all indicators that are important to safety and that display parameters not available elsewhere in the control room will be moved to a new location and height, meeting the criteria of NUREG-0700.
This location will be where the core profile map is currently on RP3. HED il80 refers to the 4kV Group Bus (fl Gen) and 4kV Bkr Fail Relays (f 12 SPT) indicator lights. These lights are not safety related, do not require close precise reading, and are supplemental indications to ators which alert the operators to the reason(s) for electrical failure

- 3.d HED 121 HED #625 HED 1626 HED 1631 legend pushbutton intensity control room lighting control room lighting emergency lighting PUBLIC SERVICE ELECTRIC & GAS The cumulative effect here involves overhead lighting and the ability to detect legend pushbutton "ON" or "OFF" status. HEDs 1626 and 1625 involve illumination levels in the control room: The control room light intensity can be controlled via individual breaker operation by the Shift Supervisor.
In this way, he can determine any lighting deficiencies and correct them as needed by his shift crew. As for HED 121, each color legend pushbutton in the "ON" condition is four times the intensity of the legend pushbutton in the "OFF" condition.
Therefore, it is judged that there is no problem in determining "ON" or "OFF" status. The cumulative effect between HED #631 (emergency lighting) and HED 121 (legend pushbutton intensity) is also negated because when the lighting in the control room decreases (e.g., emergency lighting energized) the intensity of the surrounding panel decreases while the legend pushbutton intensity remains constrant, resulting in a higher contrast ratio between surrounding panel and energized legend pushbutton.
The legend pushbutton intensity will be much greater than the surrounding panel

PUBLIC SERVICE ELECTRIC & GAS Salem Annunciators 6.1.5.5 (635) 6.2.2.3 (711,714, 715) 6.3.1.1 6.3.1.2 (530, 531) (533,534, 535) 6.3.1.3 6.3.1.4 (538) The acoustic design of the control room will ensure that auditory signals are readily detected.
Background noise levels will not exceed 65 dB(A). Auditory signals may be coded. For example, to prioritize signals, or to direct operator attention to a particular area in the control room. Coding methods should be distinct and unambiguous, and will not conflict with other auditory signals. Coding by intensity will not be used. Annunciator warning system will consist of three (3) major subsystems: (a) an auditory alert subsystem, (b) a visual alarm subsystem, and (c) an operator response subsystem.
The limits or setpoints for initiating the annunciator warning system will meet the following:
(1) alarms will not occur so frequently as to be considered a nuisance by the operators, (2) setpoints will be established to give operators adequate time to respond to the condition before a serious problem or automatic action takes place, (3) the setpoints and reset points will be wide enough "dead band" so as not to become a nuisance alarm
- General alarms, alarms that require the control room operator to direct an auxiliary operator to a given plant location for specific information, will only be used for conditions that allow adequate time for auxiliary operator action and subsequent control room operator action. Annunciators with inputs from more than one plant parameter setpoint will be avoided. Multi-input alarms that summarize single-input annunciators elsewhere in the control room are an exception.
Alarms for any shared plant systems will be duplicated in both control rooms. First out annunciator panels will be provided for the reactor system and turbine-generator system to identify the initiating event. The first out panel will consist of separate annunciator tiles for each of the automatic trip functions.
In the event of a trip, the tile associated with the event will illuminate, and not others. First out panels will be located directly above the main control workstation for the system. Logical prioritization will be applied such that operators will be able to differentiate the most important or serious alarms from less important ones *
- 6.3.1.5 (540, 541 710,712) 6.3.2.1 (716) 6.3.3.1 (543) PUBLIC SERVICE ELECTRIC & GAS Examples of priority levels are as follows: FIRST PRIORITY ALARMS
- Plant shutdown (reactor trip, turbine trip)
- Radiation release
- Plant conditions which, if not corrected immediately, will result in automatic plant shutdown or radiation release, or will require manual plant shutdown.
SECOND PRIORITY ALARMS
- Technical specification violations which if not corrected will require plant shutdown
- Plant conditions which, if not corrected, may lead to plant shutdown or radiation releases THIRD PRIORITY ALARMS
- Plant conditions representing problems (e.g., system degradation) which affect plant operability but which should not lead to plant shutdown, radiation release, or violation of technical specifications.
Color and/or auditory methods will be use for priority coding. Cleared alarms will have a dedicated, distinctive audible signal which should be of finite duration.
The individual tile will have a flash rate twice or one-half the normal flash rate to allow discrimination.
The annunciator signal should be such that operators can reliably discern the signal above the ambient control room noise. A nominal value of 10 dB(A) above background will be used. The signal intensity, if adjustable will be controlled by administrative procedures.
The annunciator auditory alert mechanism will automatically reset when it has been silenced.
Separate auditory signals will be provided at each workstation within the primary operating area. Visual alarm panels will be located above the related controls and displays which are required for corrective or diagnostic action in response to the alarm. Each annunciator panel will be identified by a label. The label height will be consistent with a subtended visual angle of at least 15 minutes when viewed from a central position within the primary operating area. If lamp replacement requires legend tile removal, there will be a way to ensure that the tile is replaced in the correct location

- PUBLIC SERVICE ELECTRIC & GAS Specific guidelines for visual recognition and identification of alarm tiles are as follows: Tiles on an annunciator panel will use flashing illumination to indicate an alarm condition.
The flash rate will be from three to five flashes per second with approximate equal on and off time. In case of flasher failure of an alarm tile, the tile light will illuminate and burn steady. Visual alarms will be organized as a matrix of visual alarm tiles within each annunciator panel. Visual alarm tiles will be grouped by function or system within each annunciator panel. The vertical and horizontal axes of annunciator panel will be labeled with alphanumerics on the left and top sides. No more than 50 tiles per matrix is recommended.
Blank or unused annunciator tiles will not be illuminated.
Annunciator tile wording will be in short concise messages.
Abbreviations and acronyms will be in accordance with the Salem human factors guidelines.
Tiles will address specific conditions.
Visual tile readability will conform to the guidelines of NUREG-0700 Section 6.3.3.5. Controls for the operator to include the following four: These functions will conform Section 6.3.4.1. respond to the annunciator system will silence, acknowledge, reset and test. to the guidelines of NUREG-0700 Repetitive groups of annunciator controls will have the same. arrangement and relative location at different workstations.
The responses control will be coded for easy recognition (e.g., color, shape, demarcation).
Annunciator response procedures will be available in the control room. They will be indexed by panel indentification and annunciator tile coordinates
