1.0 INTRODUCTION
The following keywords, abbreviations, and acronyms are used through-out the manual. DCRDR - Detailed Control Room Design Review CR/CB - Control Room / Control Board PTN - Turkey Point Nuclear Plant HFE - Human Factors Engineering HED - Human Engineering Discrepancy PC/M - Plant Change / Modification O) ( FP&L - Florida Power and Light Company 1.1 GENERAL To comply with Supplement 1 to NUREG-0737 requirements, a detailed Human Factors Engineering Review of the Florida Power & Light Turkey Point Plant Units 3 and 4 control room / control board was perforraed. The objective was to identify and correct design discrepancies and l improve the ability of control room operators to prevent or cope with accidents. The basic guidance document for this effort was NUREG-0700, l Guidelines For Control Room Design Review. i Human engineering discrepancies were identified by the ESSEX Corpora-tion. Resolution of discrepancies was accomplished by FP&L and Bechtel l l Engineering staff. The implementation of enhancements was performed by FP&L's construction department. O 1-1
1.2 OBJECTIVE l (. This document provides guidance in the application of HFE principles during the design and evaluation of future changes at the Turkey Point Nuclear Power Plant. It contains guidance for future control panel modifications to ensure continuity and consistency with the existing panel layout and enhancement schemes. In addition to general HFE guidelines, it also contains standard hardware specifics as well as established practices and provisions that are adopted and approved for use at PTN. Certain sections in this guidance manual are subject to change as the plant and its systems are modified. These sections should be updated periodically to reflect current plant configuration. The most vulner-able sections are in Appendices A and B, Main Control Board Layout and Annunciation Window Layouts, respectively. 1.3 SCOPE This document is written in the context of reviewing HFE conformance for plant change / modifications involving changes to an existing system in the plant. If an existing system is to be replaced in its entirety by a totally different system, gu' ' tes for such evaluation may go beyond the scope of this document. Criteria for reviewing an item that is unlikely to be changed or replaced, such as the control room itself or its ventilation system, are not included in this document. The ventilation system must be reviewed against NUREG-0700, Section 6.1.5.2. For all practical purposes, the use of PTN standard hardware, as listed, is encouraged. If a nonstandard part is used, e.g., a slide switch, it must be reviewed against NUREG-0700, Section 6.4.5.2. In the event a plant standard component part is no longer available or a model has been discontinued, it is the responsibility of the design 1-2
engineer to decide on , an acceptable alternate. The requirements of f~ NUREG-0588 must be considered. ( 1.4 STRUCTURE AND USE This document is structured with the user's convenience in mind. It is organized to provide general guidelines first, followed by a component section which addresses each panel component in turn. Section 4.0 stipulates HFE requirements for computer-driven instrumentation. The document concludes with the appendices. When a PC/M involves work in the control room / control board, the responsible engineer must determine the type of hardware to use and its location on the control board. Section 2.1 of this document provides control room layout. The new device should be installed in the panel secti'on to which it is closely related. Then from Section 2.2, control board layout arrangement drawing, it is possible to determine if suf-p ficient panel space is available for the addition or if it is necessary to I reorganize existing panel mounted devices to accommodate the new change. In all probability, this step must be verified in the control room to ensure that the desired location has not been previously used for other changes. Back of panel interference possibilities also must be investigated. l Insofar as components are concerned, every effort should be made to use standard hardware if at all possible. Standard hardware is listed under Section 3.0. HFE considerations for each type of hardware are delineated under the appropriate subsection. Section 4.0 is dedicated to computer-driven instrumentation. This refers to systemc such as the SPDS/SAS, DDPS, and QSPDS that are currently installed. Future additions of this type of equipment should include HFE considerations delineated in this section. O 1-3
1 l I' l A checklist is provided after each subsection in Sections 2.0, 3.0, and 4.0. The responsible engineer or other reviewers may use the applicable checklists for verification of HFE conformance. 4 Plant specific practices, guidelines exclusively adopted for PTN 3 & 4, 1 are listed under the appendices. Exhibits and references are listed in the Table of Contents for the user's convenience. i I 4 P l f ( I J O 1-4

2.0 GENERAL 2.1 MAIN CONTROL ROOM (MCR) ORGANIZATION 2.1.1 Description The MCR area is common for the two nuclear units in an arrangement assuming complete separation of equipment, instrumentation, and cabling between them. The MCR area consists of: o A functional operating area, commonly identified as MCR, containing the main control boards where the operation of both units is monitored and controlled under normal and accident conditions o An instrumentation area containing the various instrumentation cabinets of the plant Exhibit 2.1-1 illustrates the general layout of the MCR area, including the MCR. The MCR, extending along a north-south axis is divided in two sections, one at the north for Unit 3 and one at the south for Unit 4. Each MCR section contains the following equipment: L o The main control board (MCB) of the unit consisting of: Two vertical panels (A and B) that are perpendicular to
. each other, with a third vertical corner panel (C) between them; these vertical panels are on two sides delimiting the MCR section O

One standing, "see over" benchboard console in front of the vertical panel A o One operator desk facing the console and the vertical panel A o Instrument cabinets (eight for Unit 3 and seven for Unit 4) disposed in a row, parallel to vertical panel A, behind the operator and delimiting the MCR section on a third side o A typer desk and SPDS/SAS color plotter between the two operator desks l Common for both units and centrally located between the vertical i panels A of the two units is a clock panel. 1 The instrumentation area for each unit extends behind the vertical control panels of its MCR to the adjacent walls,. delineating the MCR . area. It comprises instrument cabinets disposed in two rows parallel to vertical panel A, one row parallel to vertical panel B, and a row closing this area, extending between vertical panel B and l'.s nearest wall. The equipment between the two MCR sections for Unit 3 and Unit 4 is symmetrically arranged with respect to an east-west axis through the MCR center. The vertical panels A of the two units, separated by the common clock ' l panel, are in a row extending north-south. The corresponding vertical l panels B are facing each other. i The distribution of process system instrumentation and controls on the ' consoles and on the vertical panels A and C is identical for the two units while it is symmetrically opposite (mirror-imaged) for the vertical panels B, as seen by an operator facing them. I Only a portion of the MCB (vertical panels A, B, and C, the consoles, O and the clock panel) should be considered for future expansions or [ 2.1-3 x-= wme nnW - w~wew w x-- - - - -,w m- --- ,---, ,-,_av.-aso e,, - - - - = - - - - - - - - -
additions of instrumentation in the MCR, since it was custom designed by the A/E for FPL. Modification to vendor supplied cabinets is not advisable since it may affect various vendor liabilities, guarantees, etc. Modifications to vendor cabinets must be coordinated with the respective vendors. 2.1.2 Design Concepts The MCR was designed to satisfy the following requirements: o Each unit is equipped in the MCR with all the controls, in-strumentation displays, and alarms required for safe operation and shutdown. o Separation of equipment, instrumentation, and cabling of the two units avoids interference in operation between the MCR sections. o Adequate radiation protection for personnel during accident conditions is provided. o Separate ventilation system with a large percentage of recirculated air allows safe operation within the MCR under accident conditions. o MCR location over the cable spreading room allows all control wiring to enter the MCR via slots in the floor, directly beneath the panels in which the wires are terminated. o Fire prevention design minimizes combustible material in the MCR, and uses flame resistant boards, metal enclosures for all electrical wiring and devices, amd flameproof sealing of cable slots in the floor. o Functional, system-oriented distribution of the instrumentation and controls on the main control boards (MCB) of the MCR 2.1-4
/ s\
minimizes operator errors and the response time to events
'V requiring timely action.
o Instrumentation and controls most frequently utilized during the normal operation are installed in the consoles. o Instrumentation and control's for less frequent operation modes such as startup, shutdown, or accident conditions are installed in the vertical panels. o Selection of systems and the distribution of corresponding instrumentation and controls among the available console and panels to separate the primary loops or Nuclear Steam Supply Systems (NSSS) from the secondary loops or the Balance of Plant (BOP) systems. o The vertical panel A and the console provide complimentary O distribution of functions within the NSSS and BOP instru-mentation, e.g. meters and trend recorders on the vertical panel A positioned in front of the censole sections, containing functionally related control stations and position indicators. i P O V 2.1-5

2.2 MAIN CONTROL BOARD (MCB) ORGANIZATION 2.2.1 Criteria The main objective of an efficient MCB organization is to provide an arrangement that allows the operator to have within his view and reach, with a minimum effort, the displays and controls required during the various modes of operation of the unit. The MCB organization for Turkey Point Units 3 and 4 has pursued this objective while applying the following criteria: o Functional, system-oriented arrangement of displays and controls. o Separation of NSSS and BOP instrumentation. o Grouping of systems required for various operating modes of the unit on different sections of the MCB. Special emphasis for a central arrangement with easy access for those required during the normal operation of the plant. Systems utilized in less frequent operations, like startup and shutdown or those for post-accident conditions, are
- assigned to MCB sections in the vertical panels, so as not to interfere with the normal' operation from the console.
l 2.2.2 Specific _ PTN Design The adopted design for the MCB, as indicated in Section 2.1, consists of: o Two vertical panels A and B (VPA and VPB) i R. i M 2.2-1
o One vertical panel C (VPC) h, o One "see-over" benchboard console (BC) The BC, VPA, and VPB are each divided in adjacent sections (U e unit ' number): UC01 and UCO2 for the console; UC03 and UC04 for VPA; and UC05 and UC06 for VPB. UC01 and UC03 contain instrument.ation for NSSS; UCO2 and UC04 for BOP systems. The process systems assigned to BC and VPA are essentfally the same and their physical location follows a .similar . spatial distribution. All of these process systems and the corresponding instrumentation are required for the normal operation of the plant. The vertical panels VPA, VPB, and VPC contain an upper portica, slightly sloped (=12 degrees) towards the MCR, on which the unit ; annunciator windows, functionally grouped in ten modules, are installed. (3 The VPA contains most of the displays consisting of meters (which can U be seen by an operator standing in front of the BC), recorders, int're-quently used controls, and annunciators. The VPB and VPC contain the engineered safety features, systems required for post-ac:! dent condi-tions, and plant auxiliary systems. The benchboard console (BC) is designed to allow a standing operator access to most of the controls required during normal operation, and while looking over it, being able to monitor displays on VBA and VBC. The BC comprises a vertical panel used basically for several meters and recorders, and a sloping panel utilized for controls and status indicators. The BC contains the majority of controls (i. e . , control switches, selector switches, controls stations), status indicators, and a limited number of displays (i.e. , meters and recorders). The common clock panel (CP) contains a window annunciator module, two clocks, and indicating lights of the vital ac ground detector. The CP extends between the VPAs of Units 3 and 4 at the level of their sloped i upper annunciator panel portions. ' 2.2-2 _ -____..__...a

q 3.1.7 The system is powered by 125 VDC. Lamps are on 24 VDC and V logics are on 12 VDC. 3.1.8 When a new alarm window is required, the window should be located close to its related instruments and controls (see Exhibit 3.1-1 and Appendix B for available spare window locations). 3.1.9 In addition, the new window should be grouped together with its associated subsystem alarm windows (see Appendix B). 1 3.1.10 Consideration should be given to the use of a single window for a number of related alarm inputs from a single system. 3.1.11 For a multi-input alarm window, consideration should be given to the need for reflash capability. For example, with tank level high/ low alarms, it is apparent that after a low level alarm, it is unlikely that a high level alarm will occur shortly afterward; thus reflash capability is not a necessity. On the other hand, fcr tank level high/high-high alarms, the high-high alarm could occur shortly after the high level alarm if no corrective action is taken; thus the reflash capability is a desirable feature for this alarm function. 3.1.12 Each multi-input card can accoramodate a maximum of four independent alarm inputs. l 3.1.13 Where a multi-input annunciator is used, an alarm printout capability should be provided. The specifics of the alarm should be printed on an alarm typer with sufficient speed and buffer storage to capture all alarm data. 3.1.14 Alarms for a shared plant system should be located on Panel X or displayed on both units. 3.1.15 To maintain a " dim board" concept, all alarm windows should be designed to maintain on dim when the plant is operating normally. 3.1-4
n 3.1.16 The annunciator circuit should be designed such that failure of the annunciator circuit will not cause failure in the equipment associated with the alarm. 3.1.17 The set point for initiating the alarm should not occur so frequently as to be considered a nuisance by the operator. 3.1.18 The set point should be established to give operators adequate
'Jme to respond to the warning condition before a serious problem develops.
3.1.19 When general alarms are used, sufficient time should be allowed for auxiliary operator action and subseque.nt control room operator action. 3.1.20 All first-out annunciator windows for reactor trip should be grouped together within the demarcated area on Panel C. O V 3.1.21 All first-out annunciator windows for turbine generator trip should be grouped together within the demarcated area on Panel - E. 3.1.22 All window tiles should'be prioritized as follows: Red Level 1 Immediate operator action required. Blue Level 2 Prompt operator action required. White Level 3 Operator attention or action required only after level 1 and 2 alarms have been attended. l l 3.1.23 For window tile details, see Appendix B. Tiles are numbered 1 through 54, preceded by a panel alphabet. To prevent the possibility of interchanging tiles , all tiles are identified by unique location designators. (Examples: A7 is on Panel A, Row 1, Column 7; B23 is on l Panel B, Row 3, Column 5.) 3.1.24 If an alarm window is deleted, its tile should be replaced by a i t blank tile. l l 3.1-5

3.2.1 Select the appropriate meter type for the intended application (see Exhibit 3.2-1). 3.2.2 The meter should be located in close proximity to its associated controls and annunciator. 3.2.3 The meter should give operators all parameter values in normal, abnormal, and emergency situations except for narrow range displays. 3.2.4 To prevent operator confusion, it is essential that the meter be identified as to whether it reflects demand or actual status. 3.2.5 To prevent interference with the readability of the meter, it is essential that there is no glare on the meter. 3.2.6 When the meter fails or becomes inoperative, the failure should be apparent to the operator (e.g. , through off-scale indication). 3.2.7 An identifying label should be installed on top of the meter. The label shou'd carry the meter's tag number and its function. For label details, see Appendix E. l 3.2.8 Meter scales should be graduated and numbered so that readings are related in a direct and practical way to the operator's task. l 3.2.9 Scale units should be consistent with the degree of precision and accuracy needed by the operator. 3.2.10 All displays should indicate values in a form immediately usable by the operator- without requiring conversion. 3.2.11 Percentage indication may be used when the parameter is mean-ingfully reflected by percentage. 3.2-1

3.2.12 Scale ranges may be expanded or contracted by multiplying or d dividing indicated scale values by powers of ten. All such scales should be clearly marked as to whether the indicated value should be multiplied or divided, and the factor involved (e.g., 10, 100, 1000). 3.2.13 Scales for quantitative reading should contain graduations differing in length as shown in Exhibit 3.2-2. 3.2.14 No more than nine graduations should separate numerals. Major
, and minor graduations should be used if there are up to four gradua-tions between numerals. Major, intermediate, and minor graduations should be used if there are five or more graduations between numerals.
3.2.15 Graduation heights as a funciton of viewing distance should be as indicated in Exhibit 3.2-3. 3.2.16 Unless a scale is truncated, successive values indicated by unit graduations should be one of those preferred series shown in Exhibit b 3.2-4, or those values multiplied by socie power of 10. 3.2.17 Logarithmic scales should be avoided unless needed to display a large range of values. I 3.2.18 When two or more meters of the same parameter must be com-pared, scales should be compatible in numerical progression and scale organization. l 3.2.19 Where positive and negative values are displayed around a zero l or null position, the zero or null position should be located at the 12 o' clock position. 3.2.20 Character height should subtend a minimum visual angle of 15 minutes, or 0.004X viewing distance in feet. The preferred visual angle is 20 minutes, or 0.006X viewing distance. O 3.2-3

3.2.21 Type style should be simple and consistent and characters I should be uppercase letters. 3.2.22 Recommended dimensional characteristics of visual display characters and spacing are as follows: o Stroke-width-to-character-height ratio should be between 1:6 and 1:8. o Letter width-to-height ratios should be between 1:1 and 3:5. o Numeral width-to-height ratios should be 3:5. o Minimum space between characters should be one stroke wide. 4 o Minimum space between words should be the width of one character. o Minimum space between lines should be one-half the character height. 3.2.23 Individual numbers and other information on a circular scale should always be vertical. 3.2.24 Besides scale markings and scale numbering, other brief printed l material should be included on the face of the meter, such as identifi-cation of the displayed parameter, indication of the units shown, and indication of transformations required for reading (e.g., multiply by 10). 3.2.25 The needed message may be communicated by printing on the face of the meter or by an appropriate label adjacent to the meter. 3.2.26 Extraneous information not needed in using the meter should be avoided (e.g. , manufacturer's trademark or address). 3.2-5
3.2.27 The :nessage should be written as briefly as clarity permits. 3.2.28 Only standard manufacturer's abbreviations and commonly accepted abbreviations shculd be used. 3.2.29 The meter display should normally contain black markings on a white background. 3.2.30 For vertical meter scales, scale values should increase with upward movement of the meter pointer. 3.2.31 For circular meter scales, scale values should increase with clockwise movement of the meter pointer. 3.2.32 For horizontal straight scales, scale value should increase with pointer movement to the right. 3.2.33 Pointer tips should be of shapes and colors shown in Exhibit O- 3.2-1. i 3.2.34 Pointer tips should be positioned to minimize concealment of scale graduation marks or numerals and should be close to the scale to avoid parallax errors. 3.2.35 Zone markings should be used to show the operational implica-tions of various readings such as operating range, upper limits, lower ! limits, or danger zone. Exhibit 3.2-5 shows examples of desirable zone l markings. l 3.2.36 Careful consideration should be given in marking the zones. In many cases, the normal range increases as power increases. Following a i plant trip most parameters will read differently, probably lower, and may reach out-of-tolerance coded band ranges.

3.8.1.9 Procedures should be established for handling communications during an emergency and these procedures must be known by all operators. 3.8.1.10 The requirements for switching depend on the procedures for use of the sound-powered telephone system. 3.8.1.11 A complete set of cords should be provided at each patch panel, when used for sound-powered phones, if cord-type patching is used. 3.8.1.12 Use of walkie-talkies should be prohibited in areas close to low level analog or digital equipment which is affected by the frequency bands used. 3.8.1.13 When there are more than two parties on a channel operating at separate locations, procedures must provide for speaker identification. 3.8.1.14 A supply of replacement walkie-talkie batteries should be stored in an accessible, well-marked space and a sufficient stock kept to support long periods of continuous operation in case of emergency. 3.8.1.15 Procedures should be established for the use of the fixed-base UHF system. 3.8.1.16 Operators should be familiarized with the proper way to speak on the announcing system. 3.8.1.17 Emergency face masks should be equipped with diaphragms that are specially designed to transmit speech. The diaphragms should be able to separate voice from exhaust valve action. 3.8.1.18 If not equipped with diaphragms, masks should be equipped with an electronic speech system which picks up the voice with an internal microphone and transmits it to a loudspeaker attached outside l the mask. 3.8-2 i

3.8.1.19 Provisions should be made to ensure complete internal and external backup communications during an emergency. 3.8.1.20 Communications equipment should be usable by personnel wearing protective gear without impeding their tasks. I J i s } I I I i i i O 3.8-3
l 1 3.8.2 Conventionally Powered Telephone System 3.8.2.1 Communication devices should be easily accessible and un- i obstructed. They should be labeled and color-coded. ! 3.8.2.2 A conventionally powered telephone system must provide good frequency response in that portion of the auditory spectrum most essen-tial for intelligibility. Standard telephone bandpass (200-3300 Hz) is acceptable. 3.8.2.3 Handsets for a conventionally powered telephone system should incorporate the following features: o Size and shape should be compatible with operator's hand size and mouth-ear distance (standard telephone dimensions are acceptable). o Should maintain firm ear contact by receiver while transmitter p\ is positioned to receive voice waves directly from mouth. i o Cords should be of non-kink or self-retracting type. o Cords should be of sufficient length to permit reasonable operator mobility. l
- o Cords should be positioned so as to avoid entangling critical controls or endangering passing traffic.
l o Vertically mounted handset cradles should be designed and l located to prevent the handset from being knocked out of the cradle by passing traffic. t o Where multiple telephones are located close together, they should be coded to indicate circuit or function. j 3.8-4 l
l 1 o If a press-to-talk button is used, the button should be con- j venient for both left- and right-hand operation. 3.8.2.4 For a conventionally powered telephone system, switching should be designed and/or programmed to minimize delay in making dcaired connections under both normal and emergency conditions and to give the control room automatic priority of access to the switching system. 3.8.2.5 For a convendonally powered telephone system, loudness of ringing should be adjustable at the individual telephone equipment. 3.8.2.6 When transmitters within the conventionally powered telephone system are used as a microphone input to the announcing system, the transmitter should be compatible with the rest of the announcing system. O O 3.8-5
3.8.3 Sound-Powered Telephone System O O l 3.8.3.1 Sound quality of a sound-powered telephone system should i provide good frequency response from 200 to 3300 Hz and in-phase feedback to the user. 3.8.3.2 Headsets for a sound-powered telephone system should incor-porate the following features: o Earphone cushioning should provide comfort for extended periods of wear. Earphones should cover the outer ear, without causing uncomfortable pressure. o Supporting structure of earpieces should not impose discom-forts of weight, concentrated pressures, or metal contact with the skin. o The earpiece should be held firmly in place, yet be easy to . d remove. o Headsets should provide hands-free operation. This may have to be compromised to accommodate a push-to-talk switch in anticipation of possible use in areas of high ambient noise. l 0 Binaural headsets should be available for use by control room personnel when they must leave the control room for plant areas with high ambient noise levels in order to communicate with the control room from these areas. Headsets should l attenuate the ambient noise level to less than 85 dB(A). l o A well-marked and accessible place should be provided for headset storage. l 3.8.3.3 The need for ringing must be determined depending on the l sound-powered telephone system procedures. If ringing is not installed, the user should be provided with the capability for directly switching 3.8-6
the sound-powered transmitter to the page system so that a desired
' O party can be called to the line.
y/ ; 3.8.3.4 Plug-in jacks for the sound-powered telephone system should be provided within the control room. Jacks should be located close to the work stations to prevent the need for long cords and should not accom-modate plugs of conventionally powered phones. t 3.8.3.5 Patch panels, when used for sound-powered phones, should be conspicuously marked and located in reasonably accessible areas.

3.8.4 Walkie-Talkie Radio Transceivers
.O 3.8.4.1 Walkie-talkie radios should provide good frequency response from 200 to 3300 Hz, and sufficient dynamic range and gain to handle instantaneous speech pressures and to develop the necessary signal 1(vel at the headphone or loudspeaker of the walkie-talkie.
3.8.4.2 Radio frequency should be chosen to provide broad area walkie-talkie communication to the control room. One consideration of frequency selection should be radio-wave penetration of metal or reinforced con-crete barriers which at certain frequencies would tend to attenuate or bounce the signal. 3.8.4.3 Walkie-talkies should be small, light, and easy to carry. Their use should leave one hand (preferably both) available most of the time for other tasks and the microphone should be integrated into the trans-ceiver package. l l t I 3.8-8 l___ _ _ _ _ _ , - _ _ . _ . _ _ . _ _ _ _ _ _ . , . _ , _ _ _ _ _ _ _ _ _ _ _ . . - _ _ _ - _ _ _ . _ _ _ _ _ _ _ - _
3.8.5 Fixed-Base UHF Transceivers l O 3.8.5.1 Fixed-base UHF transceivers should provide good frequency t response from 200 to 3300 Hz, and sufficient dynamic range and gain to handle instantaneous speech pressures and to develop the necessary signal level at the loudspeaker of the transceiver. 3.8.5.2 For a fixed-base UHF system, gain should be adjustable, but the gain control should be limited so that even at its lowest setting an audible signal is still present.

3.8.6 Announcing System
.O 3.8.6.1 The announcing (page) system should provide a good frequency response. At a minimum, telephone quality is required (200 to 3300 Hz);
higher intelligibility is achieved by a band of 200 to 6100 Hz. 3.8.6.2 The need to page only certain selected areas should be deter-mined depending on the announcing system procedures. 3.8.6.3 Microphones for an announcing system should be protected <
! against breath blast and moisture condensation.
3.8.6.4 Frequency response of the microphone should be compatible with that of the rest of the announcing system. Microphones should have high sensitivity to speech signals. 3.8.6.5 If the powered telephone system is used to provide microphone
- q input to the announcing system, the telephone system should contain V transmitters of quality compatible with that of the announcing system.
3.8.6.6 Microphone input should be provided in the control room and
- dynamic range should permit 50 dB variations in signal input.
l 3.8.6.7 Loudspeakers should be provided in the control room and other ! areas where control room personnel might be (e.g., restrooms, eating areas, locker rooms, etc.). Speakers should be placed to yield an intelligible level of signal throughout the area. L 3.8.6.8 Loudspeakers should be placed to adequately cover all neces-
~
sary areas without " dead spots." l l 3.8.6.9 Where speaker reverberation is a . problem, many low power i 1 speakers should be considered rather than a few powerful speakers. O 3.8-10
3.8.6.10 Speaker volume should be adjusted to ensure that speaker communications will not prevent detection of auditory alarms. Loud-speakers located within the control room should have individual volume controls. 3.8.6.11 Audio gain control should be limited to preclude reducing volume below an audible level. 3.8.6.12 Control room inputs to the announcing system should have priority over any other input. The control room input should be capable of interrupting or bypassing announcements. f O

Associated with satisfactory conditions. Slack-Normally used as the background color, i.e., the color of blank character spacee. Also used as the action character when reverse field coding is employed. White- A non attention getting color. It should be used for standard siphanumeric text or tables where the information is contained in the characters and not the color. Might also be used.for labels, coor-dinate axes, dividing lines, demarcation brackets, etc. A Cyan (light blual-(Same as white)-Might be used in conjunction U with white to provide some amount of noncritical discrimination (e.g., use cyan for tabular column headings a xf demarcation lines; use white for alphanumeric deta). 8/ue (dark)-Poor contrast with dark background. Not recom-mereded for attention getting purposes or for informationteering data. Use for labels and other advisory type messages. Magenta-A harsh color to the eye.

APPENDIX C ANNUNCIATOR WINDOW TILE SPECIFICATION C1.0 MATERIAL SPECIFICATION C1.1 Annunciator tiles can be either purchased from Beta Products, Inc. or fabricated by FPL's Equipment Repair Center. Tiles are priori-tized by color according to their level of importal.ce as follows: Level Operator Action Tile Color Front Back 1 Immediate White Red 2 Urgent White Blue 3 Normal White White i 1 (first out) Immediate White White C1.2 Beta Tiles (N Purchase the following from Beta Products, Inc., P.O. Box 5004, 1416 h Upfield Drive, Carrollton, Texas 75006, Telex 74-0701/(214) 242-0644: P/N 301479-003 2x3 window, blank, white P/N 116082-001 Thumbscrew Apply a self-adhesive colored foil, Chartpak or Pantone acetate gloss, Cat. Nos. PF01 (red) and PF02 (blue) to the back of level 1 and level 2 tiles, respectively. Level 3 tiles need no colored foil on the back.

f.f - t [ EXHIBIT C-1: Tile Specifications C-2
Level 1 tiles are fabricated from 1/8-inch white plastic sheets (color (]) ( 2283) on the front and a 1/8-inch red plastic sheet on the back glued together to form a single composite tile. Level 2 tiles are fabricated in a similar manner, except a 1/8-inch blue plastic sheet (color 2051) is glued on the back. Level 3 tiles are fabricated from a single 1/4-inch white plastic sheet. C1.4 Tiles are engraved by FPL's equipment repair center in accordance with the guidelines set forth in Sections C2.0 and C3.0 of this specifica-tion. Thumbscrews are flared in place after engraving. C2.0 LEGEND SPECIFICATION C2.1 The criteria delineated below shall be used for tile engraving. Engraved characters shall be filled with non-gloss black paint. Tile dimensions are 1-7/8 inches by 2-7/8 inches. The engraved portion of the tile is 1-1/4 inches by 2-1/4 inches, o Character height .21875 inch (7/32 inch) measured from the top of the character to the bottom of the character. o Character width .15 inch (5/32 inch). o Stroke , width .042 inch (3/64 inch). o Space between lines .125 inch (1/8 inch) measured from the bottom of 'the characters of one line to the top of the characters of the next line. o Space between words .15 inch (5/32 inch) o Space between characters .042 inch (3/64 inch) o Wide character width (M,W) .020 inch (13/64 inch). The dimensions listed above will accommodate four lines of text, no more than 13 characters per line, and at least 1/8-inch borders. An example of a Turkey Point annunciator tile is shown in Exhibit C-2. C3.0 USE OF ABBREVIATIONS AND ACRONYMS C3.1 To prevent ambiguity in messages, the use of whole words is desired. However, labeling space is constrained by annunciator size, and as such, whole word messages often cannot be used. Abbreviations and acronyms are used to increase the amount of information presented within the compact space of an annunciator. In order to relay information most effectively, this nomenclature must be consistent and clear. Several rules and guidelines should be considered when using abbreviations and acronyms. l C-3

C3.2 General Use Requirements o ONLY the abbreviations and acronyms in the Turkey Point constrained dictionary shall be used and ONLY when space constraints require shortened forms of words. o If available character space exists on a label, spell out the message. Exceptions: HI, LO, TEMP, PRESS, RHR, RWST, RPS, RCP, RCS, VCT, SG, CCW. o The same abbreviation shall be used for all tenses and for both singular and plural forms of the word. If a plural form is necessary, use an apostrophe with the abbreviation to ensure the term cannot be confused with another. (Often the addition of a single letter can change the meaning a word conveys.) Examples: RM - RM's ; RCP - RCP's Verb tense should 'only be used when serious misinterpretation of the message is possible. o Punctuation marks should be avoided since they use space and do not contribute to the message. p o An abbreviation has only one associated meaning; one abbre-Q
~
viation exists for each term. o Single-word labels of four or fewer letters should not be abbreviated. o Words of four or fewer letters should seldom, if ever, be abbreviated. Exception: Word is within a phrase repre.nented by an acronym. Specific exceptions: LOW-LO o Two-character abbreviations are avoided. The number of two-character combinations is limited and word meaning is generally not conveyed with only two letters. o Words depicting extreme emergency conditions (e.g. , DANGER, CAUTION, RADIOACTIVE MATERIALS, RADIATION AREA) should never be abbreviated. o Words for which no abbreviation is listed should appear fully spelled out. Examples where abbreviations are not recom-mended: The word is used infrequently. 1 1 C-5 i
1 The abbreviation does not significantly decrease the num-l ber of characters required.
- The only acceptable abbreviation has other meanings associated with it.

'd ABBREVIATIONS AND ACRONYMS There are many methods and techniques for making abbreviations. The fol-lowing table demonstrates the various abbreviations for " append" and
" execute. " Because of this variety, it is necessary to develop an approved plant-specific abbreviation list to ensure consistent usage.
The following pages list abbreviations and acronyms in use at Turkey Point Plant Units 3 and 4. Abbreviation Technique Description Append Execute References ABBREV Retain the first syllable APPN EXEC McBride et al intact and progressively (1981) delete vowels and then consonants from the remainder of the word. Contraction Retain the first letter APND EXTE Hodge and and the last letter of Pennington the word but eliminate (1973) some of the internal O letters. b Frequent Delete letters from a APPD EXCU Moses and Letters word according to their Potash (1979) Drop frequency of occurrence in the English language. The highest-frequency letters are successively eliminated until the desired abbreviation length is achieved. l However, the first letter of the word is , never eliminated. 1 i Phonetic Form abbreviations APND XQT Hirsch-Pasek (Phonics) that when pronounced et al (1982) I sound like the original word. l Truncation Retain the first few APPE EXEC Hirsch-Pasek I contiguous letters of et al (1982) a word and delete the Hodge and rest.
