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 performed.

The objective was to identify and correct design discrepancies aad improve the ability of control room operators to prevent or co'pe with accidents. The basic guidance document for this effort was NUREG-0700; Guidelines For Control Room Design Review.

Human engineering discrepancies were identified by the ESSEX Corpora-tion. Resolution of discrepancies was accomplished by FP&L and Bechtel:

Engineering staff. The implementation of enhancements was performed by FP&L's construction department.

1. 2 OB /ECTIVE 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 reQect 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, guidelines 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 1

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 section to which it is closely related. Then from Section 2.2, control board layout arrangement drawing, it is possible to determine if suf-ficient panel space is available for the addition or if it is necessary to 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 locati'on has not been previously used for other changes. Back of panel interference possibilities also must be investigated.

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 systems 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.

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.

Plant specific practices, guidelines exclusively adopted for PTN 3 & 4, are listed under the appendices. Exhibits and references are listed in the Table of Contents for the user's convenience.

2.0 GENERAL 2.1 MAIN CONTROL ROOM (MCR) ORGANIZATION 1.1.1 ~D 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:

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 2.1-1

UNIT' UNIT +

EXHIBIT 2.1-1: Main Control Room Layout-

Cl 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 Common for both units and centrally located between the vertical panels A of the two units is a clock panel.

The instrumentation area for each unit extends behind the ver tical 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 its 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 panel, are in a row extending north-south. The corresponding vertical panels B are facing each other.

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.

Only a portion of the MCB (vertical panels A, B, and C, the consoles, and the clock panel) should be considered for future expansions or 2e1 3

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 Desi n Conce ts 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.

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 Pire 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

minimizes operator errors and the response time to events requiring timely action.

o Instrumentation and controls'ost frequently utilized during the normal operation are. installed in the consoles.

o Instrumentation and controls 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 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 console sections, containing functionally related control stations and position indicators.

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.

2.2.2 S ecific PTN Desi n The adopted design for the MCB, as indicated in Section 2.1, consists of o o Two vertical panels A and B (VPA and VPB) 2.2-1

0 o One vertical panel C (VPC) o . One "see-over" benchboard console (BC)

The BC, VPA, and VPB are each divided in adjacent sections (U = unit number): UC01 and UC02 for the console; UC03 and UC04 for VPA; and UC05 and UC06 for VPB. UCOl and UC03 contain instrumentation for NSSS; UC02 and UC04 for BOP systems.

The process systems assigned to BC and VPA are essentially 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 portion, slightly sloped (="12 degrees) towards the MCR, on which the unit annunciator windows, functionally grouped in ten modules, are installed.

The VPA contains most of the displays consisting of meters (which can be seen by an operator standing in front of the BC), recorders, infre-quently used controls, and annunciators. The VPB and VPC contain the engineered safety features, systems required for post-accident 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 upper annunciator panel portions.

2.2-2

The MCR instrumentation is distributed on the MCB panels according to the following spatial allocation of the main process systems:

Bench Console BC UC01 RCS; NIS; RCCS; CVCS; SPDS UC02 SG; FWS; TURB; GEN; DG; AFW; COND SYS; EL SYS Vertical Panel A VPA UC03 CVSC; RCS; SPDS; SG; RCCS UC04 TURB; CWS; GEN; EL SYS Vertical Panel C CTMT Vertical Panel B Unit 3 3C05 ECCS; CTMT VENT; ACC; RHR; CCW; AUX BLDG VENT 3C06 MISC; DG; QSPDS; CI; SI; CS Vertical Panel B Unit 4 4C05 CCW; RHR; ACC; CTMT VENT; ECCS; AUX BLDG VENT 4C06 CS; SI; CI; QSPDS; DG; MISC The VPAs and BCs of both units are identical. The VPBs are mirror-images as follows:

Section 3C05 is mirror image of Section 4C05.

Section 3C06 is mirror image of Section 4C06.

3. 0 COMPONENTS 3.1 ANNUNCIATOR SYSTEM 3.1.1 Each PTN unit is equipped, with ten annunciator alarm panels (A through 3). Panel X is shared by both units. Each panel consists of 54 windows arranged in a 6 x 9 matrix. See Exhibit 3.1-1 for details.

3.1.2 The Constalert Series 5000 annunciator system manufactured by the BETA Corporation is standard for the PTN plant.

3.1.3 The system is comprised of the following equipment:

Lamp Logic Cards CSF-7 0301831-8C8K Lamp Logic Card DSF-9 4301617-1C1K Flasher Control Card 4300830-1 ReQasher Relay Card f301975-1 Power Supply Card 0300841 Multiple Input Card 4301937-1 Dim Light Control Card f301133-1A21 Power Supply AC-151 DC to DC Converter 4301509 3.1.4 The system has three operating sequences: the CSF-7, standard dim-fiashing-momentary-self-reset sequence; the reQash sequence; and the DSF-9, first-out sequence as shown in Exhibits 3.1-2 and 3.1-3.

The refiash sequence is the repeat of the standard sequence.

3.1.5 Control function consists'of one set of three pushbutton switches for each unit: Acknowledge, Silence, and Reset (for first-out only).

3.1.6 A single horn with a different sound pattern for each unit is provided for audible annunciation.

P 3.1.7 The system is powered by 125 VDC. Lamps are on 24 VDC and 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).

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 reQash 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, for 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 accommodate a maximum of four independent alarm inputs.

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

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 'he 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 time 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 subsequent 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.

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.

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 II designators. (Examples: A7 is on Panel A, Row 1, Column 7; B23 is on Panel B, Row 3, Column 5.)

3.1.24 If an alarm window is deleted, its tile should be replaced by a blank tile.

3.1-5

3.1.25 This document does not provide guidance to modify or change the auditory alert system. Any changes to the auditory system require a human factors review.

3. 2 METERS 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 reQects 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 should carry the meter's tag number and its function. For label details, see Appendix E.

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.

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.

3.2.12 Scale ranges may be expanded or contracted by multiplying or 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 function 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 3.2-4, or those values multiplied by some power of 10.

3.2.17 Logarithmic scales should be avoided unless needed to display a large range of values.

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.

3.2.19 Where positive and negative values are displayed around a zero or null position, the zero or null position should be located at the 12 o'lock 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.

3.2. 21 Type style should be simple and consistent and characters 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.

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 material should be included on the face of the meter, such as identifi-cation of the displayed parameter, indication of the units shown, and I

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

0 3.2.27 The message should be written as briefly as clarity permits.

3.2. 28 Only standard manufacturer's abbreviations and commonly accepted abbreviations should 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.

t 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 3~2 1 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'one 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 markings.

3.2.36 Careful consideration should be given in marking the zones. In many cases, the normal range increases as power increases. Following a plant trip most parameters will read differently, probably'ower, and may reach out-of-tolerance coded band ranges. The relationship between annunciator alarm set points and meter band range should also be 3.2-6

evaluated. The best approach is to initially apply the green/normal band. Other zone bands will be applied at a later date as use definitions are established. The bands are to be adjusted with operating experi-ence.

3.2.37 Zone markings should be conspicuous and distinctively different for different zones.

3.2.38 Zone markings should not interfere with readings on the face of the scale.

3.2.39 Zone markings should be designed for clear visibility for the planned viewing distance.

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 importance as follows:

Level 0 erator Action Tile Color Front Back Immediate White Red Urgent White Blue Normal White White 1 (first out) Immediate White White C1.2 Beta Tiles Purchase the following from Beta Products, Inc., P.O. Box 5004, 1416 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.

C1.3 Fabricated Tiles Some tile can be fabricated by FPL's Equipment Repair Center, 6001 N.W. 70 Avenue, Miami, Florida 33166, (305) 885-9731. Thumbscrews, PN 116082-001, are to be purchased from Beta.

Tiles are cut and machined from plastic sheets, Plexiglas G, to the dimensions shown in Exhibit C-1. All edges and corners are chamfered to form a smooth contour.

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'051) 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.

C-3

O TURBINE PLANT Character Height -7/32 inch Space Between Lines -1/8 inch COOLING WATER LOW PRESSURE HIGH TEMP I/8 inch Border EXHIBIT C-2: Annunciator Tile Example C-4

C3.2 General Use Re uirements 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.

o An abbreviation has only one associated meaning; one abbre-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 represented 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.

C-5

The abbreviation does not significantly decrease the num-ber of characters required.

The only acceptable abbreviation has other meanings associated with it.

C-6

APPENDIX F 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 Techni e Descri tion ~Aend 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

, letters.

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.

However, the first letter of the word is never eliminated.

Phonetic Form abbreviations APND XQT Hirsch-Pasek (Phonics) that when pronounced et al (1982) sound like the original word.

Truncation Retain the first few APPE EXEC Hirsch-Pasek contiguous letters of et al (1982) a word and delete the Hodge and rest. Pennington (1973)
