PLANT MANAGER /
DATE SCOPE This procedure discusses actions to be taken in the event of a rajor chlorine release, such as gross failure of a storage container. Minor chlorine leaks are not considered to be an emergency, and would be corrected as part of normal operator and maintenance personnel duties.
GENERAL Chlorine is used for treating the circulating water system to reduce biological fouling; Chlorine gas is extremely irritating to the mucous membranes of the eyes and respiratory tract and may be fatal if inhaled in l
very high concentrations.
I A detectable ador is produced at concentrations of 3.5 ppm in air; 15 ppm causes immediate irritation of the throat and concentrations above 50 ppm are dangerous for even short exposures.
A total of eight chlorine detectors are installed at the plant. Two chlorine detectors, CEL-19 and 20, are installed in the intake ducts to each Unit's control room ventilation system. The air intake ducts of the Control Room Pressurization System also have two chlorine detectors on the North and South ends of the Turbine Building (North end: CEL-101 and 102; South End: Cel-103 and 104). In the event of high chlorine level (2 ppm) on any of the detectors, the ventilation system automatically transfers to Mode 3 (internal recirculation).
SYMPTOMS 1.
A major chlorine leak is observed at the chlorinator equipment.
2.
The odor of chlorine is detected by plant personnel.
3.
The following main annunciators may sound:
a.
" Intake Auxiliary System" (PK13-02).
b.
" Control Room Ventilation" (PK15-06).
j AUTOMATIC ACTIONS The control rocm ventilation system may transfer to Mode 3.

Notify the Shift Foreman (Interim Site Emergency Coordinator) of the situation.
2.
Alert personnel downwind of the chlorine leak to stay clear of the area.
3.
Transfer the control room ventilation sys =m to Mode 3 if the ador of chlorine is detected within plant structures.
4.
Inflate dcor seals on access dcors to the centrol recm if tr:tnsfer of the ventillatien system to Mode 3 is required.
SUBSE00ENT ACTIONS l
1.
Render all necessary first aid (Refer to EP M-1 or EP 'M-2).
If the leak is at the intake structure, and at least two personnel are 2.
present, they should don the self-contained breathing apparatus (SCBA)
~~
~-
stored at the intake structure, protect skin surfaces, and attempt to isolate the leak if the following ccnditions are met:
a.
Both are qualified and able to use the respirators.
b.
At least one is sufficiently familiar with the chlorine system to be competent to isolate the leak.
c.
All necessary first aid or rescue actions have been ecmpleted.
l 3.
Use Appendix I for guidance to classify the emergency, and perfonn the actions required by the classification.
4.
As soon as possible, send at least two men equipped with l
self-contained respiratory equipment, protective clothing and a portable radio to the area of the release to attempt to isolate the leak.

If the main annunciator PK15-06, " Control Rocm Ventilation," has sounded, the chlorine bottles may have already been emptied. As a precaution, the men to be dispatched to the intake must wear their SCSA before leaving the control room. Attempt to approach I
the leak upwinc frcm the source. Have extra air supply bottles available' prior to entering the area of the leak.
3.
After the plume has dissipated, the fclicwing actions should be taken:
a.
Restore normal ventilation to the centrol recm, if required.
b.
Release inflatable door seals on access doors to control room, if required.
c.
Investigate the area of the release for residual chlorine.
Investigating teams should take a portable radio with them.
Chlorine cas is heavier than air and will accumulate in low areas.
If cnlorine gas is found, a portaole olower snouic be I
rigged to take suction at the low point of the affected area and exhaust to atmosphere.
NOTE: Airborne chlorine concentrations can be as'certained with a chlorine detector tube used with an air sampler. The presence of chlorine can also be detected by exposing ammonium hydroxide to the atmosphere. Chlorine reacts with ammonium hydroxide to form the white precipitate ammonium chloride.- Ammonium hydroxide can be obtained from the chemistry lab. Air samplers are also in the l
chemistry lab.
CAUTION: The investigation must be conducted by at least two persons who are equipped with appropriate respiratory equipment l
and protective clothing.

UAft PLANT MANArsER g
SC0pE This procedure discusses actions to be taken in the event that a tsunami waraing is received at the site and/or a tsunami is experienced at the site.
DISCUSSION A tsunami is a large sea wave caused by an ur.dersea earthquake. A tsunami at Diablo Canyon could result from a local earthquake, or frcm an earthquake hundreds of miles away. Tsunamis may affect the plant by interfering with the normal seawater supply to the circulating water.and auxiliary saltwater systems.
A tsunami consists of a low water period (drawdown) and a high. water period (runup). Nomally, drawdown preceeds runup, although the reverse may also be true depending upon factors such as the location of the earthquake. Generally there are two or more runup and drawdown periods although the first two are nomally the largest. The periods of runup and drawdown may last as long as 10 minutes each and may be spaced 30 to 40 minutes apart.
During drawdown, the concern is that the circulators and ASW pumps could lose suction. However, analysis of the maximum tsunami considered credible for this site indicates that both sets of pumps will continue to pump water throughout the occurrence.
If they lose suction, it should be of short duration (less than 5 minutes). During runup, the concern of flooding is not expected to occur with any likely tsunami, although the maximum credible tsunami does crest the main deck of the intake structure, and could flood the circulators.
Hcwever, the ASW pumps are protected by the watertight doors (assuming they are closed) and by the elevated opering on the ventilation shaft.
Since the opening of the ventilation shaft is higher than the water l
level which results from a maximum credible tsunami, no flooding of the ASW pumps is ever expected to occur.
The California Office of Emergency Services in Sacramento transmits tsunami warnings to the Company. The System Dispatcher in San Francisco will notify tne Centrol Operator at Diablo Canyon and inform him of the estimated time of arrival of the tsunami at Diablo Canyon.

PAGE 2 CF Tm.E:. TSUNAMI WARNING I
In addition, other agencies such as the Coast Guard, National Weather Service, or the National Oceanic and Atmospheric Administration may notify the plant before the Dispatcher. Therefore, the probability of a tsunami striking Diablo Canyon without warning is very small. If the source of the tsunami is local, ground motion will alert the operator of the possibility of a tsunami.
SYMPTOM The Control Rocm is notified by the System Dispatcher, or a cognizant governmental agency, of the time of arrival of a predicted tsunami in the plant area, or strong ground motion indicative of a local earthquake is detected (Refer to Emergency Procedure M-4
" Earthquake").
AUTCMATIC ACTIONS The following main annunciators may activate when the tsunami arrives:
1.
" Auxiliary Saltwater Syst,em" (PK0k-01).
2.
" Auxiliary Saltwater Pumps Room" (PK01-02).
mN 3.
" Auxiliary Saltwater Pumps" (PK01-03).
IMMEDIATE ACTIONS 1.
Notify the Shift Foreman (Interim Site Emergency Coordinator).
2.
Verify the Tsunami warning with the system dispatcher, if time permits.
3.
Request the Security Shift Supervisor to evacuate the intake stnJcture and instruct all personnel to remain on high ground
(+85' or above) until the threat has passed. Any entry below the
+85' level requires Site Emergency Coordinator approval while the warning is in effect.
4.
If PK01-02 (AUX sal.T WTR PPS. ROCM) is in alarm and indicates an Aux. Sal.t Water Pump Room door is open and time pemits, go to the Intake Structure to close the ASW Pump Rocm watertight door.

TFLE: TSUNAMI WARNING SUBSE00ENT ACTIONS 1.
Perform the notifications required by Appendix Z.
2.
Send an operator with a radio to the top of the road overlooking the intake structure to act as Observer. Establish comunications between the observer and the control room.
3.
Monitor ASW pump motor amps as an indicator of ASW flow, use CCW heat exchanger delta P as a back-up source of ASW flow indication.
a.
If motor amps read erratically low, indicating that the pump is losing suction, turn the standby ASW pump to MANUAL to prevent it frcm starting on low discharge header pressure.
This will prevent any darrage to the standby pump due te dry operation.
b.
If motor amps remain low on the operating pump, it should be stopped and restarted in abcut 1 minute. Repeat this, if necessary until flow is regained.
NOTE: Limit pump restans to 3 in any 30 minute period (15 i
minute period if the pump runs for 10 minutes during the 15 minutes). If the pump does not have suction (i.e. no load) each start may be counted as one-half start. Switch pumps, if required, to remain within the pump start limitations.
If the ASW pump trips on overcurrent following restart, count this as 2 starts.
Begin a controlled load reduction, to reduce heat load, if c.
ASW flow is not imediately restored.
4.
Trip the affected reactor if any of the following occur:
a.
One or both ASW pumps trip on overcurrent, and flow cannot be imediately restored.
b.
The C-9 interlock activates, which indicates:
1)
Both circulator breakers are open, or 2)
Low vacuum in the condenser.
c.
Flooding of the intake structure is reported from the observer.

PLANT MANAGER DATE l
SCOPE This procedure describes the purpose and basic description of the emergency personnel hatch, operational instructions, how to enter and leave the hatch frcm containment, and atmosphere in the event of an accident. A description of the interlocking system how to defeat and reset when required.
DISC'JSSION Purpcse and Basic
Description:
The personnel hatch is designe'd to pennit a speedy escape from the containment vessel during an accident.
(
Pulling the door operating handle through its arc will equalize the l
pressure across the bulkhead, unlock the door and swing the door open.
l Once inside the hatch, moving a second lever reverses the operation, closing the door, locking it and closing the valve.
The exact same procedure will cycle the atmosphere door and close it again.
A mechanical interlocking system prevents both doors from being opened at 1
the same time and in fact will prevent the closed door from being cycled if one door is left open accidently.
f If the door operating handle is found to be locked and sufficient time for other personnel to clear the hatch is allowed, the open door can be closed by means of the remote door operation handwheel. Rotation of the handwheel j
will close the remote door, latch it and close the vent valve, leaving the interlock system clear.
I To operate any of the four door operation handles, a force of approximately thirty-five pounds must be applied to it.
CAIJTION: This force should never be exceeded.
Remember, if the handle does not move easily, the interlock is in force and excessive force may damage the mechanism.

Movement of the pointers will show whether or not anyone is in the process of going through the hatch.
In acditicn to the pointars, there are annunciating lignts en tne exterior surfaces of the bulkheads which, when lit, indicate that the hatch is in use.
It can be assumed that the interlock is in force.if the handle remains locked for more than one minute and that remote operation will be required.
Always cycle the operating handle until the annunciating lights go out when leaving the. hatch.
PROCEDURE 1.
To enter hatch, containment or at:nosphere.

An incomplete cycle will leave the interlock in force. Cycle until annunciating lights are out.
If not completed the next user will be required to use the remote operating mechanism to fully close door for entry.
POTE 1: (Differential pressure across the bulkheads)
If a ditterential pressure across the bulkheads exists, it is possible to complete the door opening cycle with the high side of the pressure differential in the hatch barrel, but only two or three PSI will tend to force the door open.
POTE 2: If the high side of the pressure differential is in the containment vessel, a resistance will be felt at the operating handle. If a high enough differential exists, it will not be possible to open the door.

GENERAL INFORMATION The Diablo Canyon Nuclear Power Plant occupies 735 acres of coastal property about 12 miles southwest of San Luis Obispo on California's central coast.
The Diablo Canyon Nuclear Pcwer Plant is situated en the California coast about midway between San Francisco and Los Angeles.
The Atomic Energy Commission licensed construction of Diablo Canyon Unit 1 in April 1968 and Unit 2 in December,1970. The two power plants have been in operation since (date and date) respectively.
The Diablo Canyon plant uses a Westinghouse pressurized water reactor.
During normal operation, the water in the reactor is under about 2,200 pounds per sqtare inch pressure, which prevents the water from boiling event though it is heated to above 600 degrees Farenheit.

' Recovery Frcm Accidental Halts in EARS Programs 39 APPENDIX A: (Hardware) 40 OISCUSSION The purpose of the EARS is to assist the PG&E Emergency Response Organization in quantifying the offsite radiological consequences of an atomospheric radiological release resulting from an accident at the OCPP.
The system gathers data (Including meteorological, essential plant parameters, onstite and offsite real time radiation monitor readings), perfoms dispersion computations, disseminates information and displays data at various onsite and offsite stations.. These include the Control Room, the Technical Support Center, the Emergency Offsite Facility, the Corporate Incident Response Center (CIRC), and the State Office of Emergency Services (CES). stations.
33
_)..
The CR, TSC, and EOF are all capable of being the controlling station; although only one may t the controller at any one time. Any station that is not functioning s the controller can receive real time calculational infomation from the EARAUT (EARS automatic) program via connunication links.
If the links become interupted during the course of an emer still function by means of the manual EARS program (EARMAN)gency, EARS can
, using data obtained via voice connunication with the controlling station operator.
This procedure together with the Operator's Manual provides tne necessary infomation for CR, TSC, and EOF operators to power up the EARS computer hardware and run the three primary EARS programs (STATUS, EARAUT, EARMAN) on the HP-9845C desktop computer at the respective station.
The structures and contents of all EARS data files at the CR. TSC, and EOF EARS stations is given in Procedure OPP HP-3.
PROCEDURE 1.
EARS Hardware at Controlling Stations All HP hardware at the CR, TSC and EOF is covered by a service maintenance agreement with Hewlett-Packard, Inc. (see Appendix A for a complete list of hardware).
In case of any hardware failure, contact the Systems Manager of the EARS and explain your problems to him.

2.
Start-Uo Procedures The following start-up procedures assume that all power to the computer hardware is off when the EARS operator arrives at an EARS station.
a.
Set the power strip switch on. All of the equipment at each station is connected to one power strip which is located on the back of the desk console, except at the TSC-CC where it is attached to the console underneath the HP-9845C. This should turn everything on if the station was left in proper, order, with all of the individual component switches set to the "0N" or "1" position. Check to see that all of the
(
switches on all of_the components are. set to "0N" or "1" at this point.
b.
If you are at the Technical Support Center turn the Colorplot printer.
~
power switch (on the left side of the printer) to "1" or "0N".
The
" POWER INDICATOR" key should be lit and the printer self-test starts (winding and rewinding of the ribbon). When the self-test is completed (ribbon motion stops), press the "0N-LINE" button.
c.
Check to see that the 7906 disc drive RUN/STOP switch is set to "RUN".
After about one minute the front panel of the 7906 should display '0 RIVE READY'.
d.
Check to see that the HP-9845C computer power switch (on the right side of the computer) is set to "1".
The CRT should beep and begin a self-test (" MEMORY TEST IN PROGRESS" message should appear on the CRT).
When the self-test is completed, the "9845 READY FOR USE" message and a flashing cursor will appear on the CRT indicating the computer is ready for use.
e.
After the entire system at this station is turned on, check the paper reserve in both the HP-9845C internal printer and the Colarplot paper basket (if present).
Instructions on how to load a new roll of thennal paper into the HP-9845C internal printer is given in Appendix A.
Instructions to load paper into the Colorplot printer are printed on the inside of the printer cover.

Any data in the computer memory M1i be erased at power failure.
a.
b.
Any printed page inside' the Colorplot prihter has to be manually wound out.
5.
EARS Software and Flow Diaorams There are three primary EARS programs stored on the HP-7906 disc drive (select code: C:12): 1) " STATUS: for non-emergency (or idle) mode operations; 2) "EARAUT" automatic EARS program; and 3) "EARMAN" -
manual EARS program for emergency made operations.
There are two basic modes in which the EARAUT program can be operated:
CONTROL and NON-CONTROL. Only the CR and the TSC EARS stations at CCPp, and the EOF EARS station at the Sheriff's Office in San Luis Obispo can be op.erated in the CONTROLLING mode. Only one station may serve as the controller at any one time. Data-is transmitted to all or selected NON-CONTROL stations in a fixed data string containing infomation about the accident, instrument readings, calculated dose results, and messages.
In the event of a real emergency you should start the EARS station by running the STATUS program.
If the emergency made of the EARS has already been established at another controlling station, but EARAUT program will automatically be loaded from the disc and be run on the r
HP-984SC.
The flow diagrams following each program description are intended to give an EARS operator a general overview of the operator logic flow for each of the three main EARS programs. When used in conjunction with the Operator's Manual, they provide a comprehensive instruction set i s

for the programs described. The nux.cers in the flow diagrams reference other " KEY SETS" within the same program, whereas the letters reference specific entry points within the same or other
- programs, a.
STATUS When the EARS is not operated in ene emergency mode, this program allows all HP-9845C stations to log onto the system for data polling purposes. As long as this station stays ' logged on' to the system, it can be ' scheduled' automatically to go into emergency made by a CONTROL station when an emergency is declared.
When ' logged on', this program allows the operator to poll the HP-1000 at the TSC for current 15-minute averaged meteorology (MET), plant radiation monitors (RMS), or pressurized ion chambers (PIC) data. It also allows the operator to detennine the system network status, such as which stations.are currently logged on the system, and when they logged on or off. In addition, the site and area maps can be displayed,and ' dumped' to the thermal printer on the HP-9845C.
(
Jnce logged on the operator can initiate the emergency made of EARS by pressing the key under the CRT labeled ** EMERGENCY **. This will load EARAUT and thereby begin the actual assessment of the emergency.,
- 1) After the computer system at this station is up and running STATUS can be loaded and run by entering the following comands from the HP-9845C keyboard, a) Type in ' SCRATCH A', press [ EXECUTE].
b) Type in ' SCRATCH C', press [ EXECUTE].
c) Type ' LOAD " STATUS: C"' and press [ EXECUTE] key.

DRAUT PROGRAM (Non-Controller)
The EARS automatic (EARAUT) non-controller program constses of four ste, ions), EARgde (Graphics subprogram)g program for Non-Controlling subprograms: EARNCC (Central processin, EARede (Release rate calculation suborogram). and EAR edc (EAL & PAG calculation suborogram), in addition to the EARAUT main entry program. These subprograms are loaded in and out of the HP-9845C as they are needed, and are for the most part transparent to the user.
The function of EARAUT as a non-controller is to receive projections and periodic updates of plant release parameters, and observe the resulting plume displays, as based on inputs from the EARS controlling station.
EARAUT (Non-controller) can be run in either one of two ways. The us can load the STATUS program (see Section 3 of the Operator's Manual) er and wait for one of the EARS ' CONTROLLING' stations to log on as the
' CONTROLLER', or the user can load the EARAUT program and specify a non-c'ontrolling mode (see Section 4.2.of the Operator's Manual).
/ '
1.
After the computer system at this station has been started up EARAUT can be loaded and run independently of the ' STATUS' program by 3
entering the following consands from the HP-9845C keyboard, f
a.
Type in ' SCRATCH A', press (EXECUTE].
b.
Type in ' SCRATCH C', press [ EXECUTE].
c.
Typein'LCAO"EARAUT:C"'andpressthe[ EXECUTE] key.
d.
Wait for the run light in the lower right corner of' the CRT to go off.
e.
Press the [RUN] key.

EARMAN PROGRAMS The EARS Manual (EARNAN) program is the manual version of the EARS programs.
j All of its functions are perfonned at the individual HP-9845C stations independent of the operation of the other stations and the HP-1000 at the TSC. Any data inout such as MET data or source term data is manually entered from tne xeyocard. In acdition no data is transmitted to or from a station that is operating EARMAN. The operation of this orocram is similar to that of. EARAUT (see Section 4 of the Operator's Manual). EARMAN consists of four separate subprograms: EARMDE (Core subprogram), EARGDC (Graphics subprogram), EARRDC (Release rate definition subprogram), and EAREDC (EAL & PAC subprogram),in addition to the initial entry program EARMAN.
In the event of a 'fata.' hardware failure on tne HP-1000 at the TSC and/or the loss of comunications between various HP-9845C EARS stations and the HP-1000, the EARMAN program can be initiated. Essential data can be obtained by telephone consnunication via PG&E or PT&T lines with EARS operators at the othar 'CONTRCLLING STATIONS' (CR, TSC, and EOF).
1.
To lead and run the EARMAN. program type in the following somands from the keybcard.
Typein'SCRATCHA', press [ EXECUTE].
a.
b.
Type in ' SCRATCH C', press [ EXECUTE].
Type in ' LOAD "EARMAN:C"', and press [ EXECUTE].

Terms Co=non to EARAUT and EAR *VN Meteorolocical Data Inout Meteorological data from the primary and secondary MET towers are obtaineo on a continous basis through a polling program on the HP-1000 computer in the TSC. The EARAU' pr: gram can ' poll' the HP-lCCO for several foms of MET data (averaged, previous or current), all of them consisting of a data
. string containing wind direction, wind speed, lapse rate, Chi /Q, and mixing height. The Chi /Q dispersion value at 800 meters is used by the EARS programs to calculate site boundary doses used in the initial Emergency Action Level (EAL) classification, and initial dose projections.
If the EARMAN program is run, the operator is required to enter all MET data manually frcm the keyboard. For detailed instructions on inputting HET data (see Section 4.1.1 of the Operator's Manual).
Release Estimate The DCPP Emergency Procedure RB-9 (Ref. 3) is the technical basis for the EARS. release rate calculations. The radionuclide distribution, release rate and accident classification are determined by the appropriate software m

CONTROL STATIONS 3.
If no FSAR accident type is approprite, the ' Manually Specified i
Release Rate' or ' Tank or Building Inventory' pemits manual entry of radionuclide release data, either by isotope or in total noble gases and iodines, via the HP-9845C keyboard.
EAL Table The EAL classification for radiological purposes is based on site boundary (800 m) exposure rates calculated using actual MET data. The printed EAL table lists the OCPP specific Emergency Action Level based on radiological criteria only. An Emergency Action Level is classified in one of the following categories: Unusual Event, Alert, Site Emergency, General Emergency..The current calculated estimate of exposure rate and projected integrated exposure ut the site boundary is also given.
In addition the estimated plume travel time to the site boundary 10-mile radius (Plume Emergency Planning Zone (EPZ)), and 50-mile radius (Ingestion EPZ), and i
the EARS suggested current radiological action level is given. This table is printed at the start of every update period.
The ' Tech Spec Whole Body' dose type listed in the table includes the cose j
from airborne noble gas isotopes only, in accordanc'e with the Technical Specification limits. The 'NUREG-0654 (Ref. 6) Whole Body' dose, on the other hand, includes the dose from airborne noble gas isotopes plus those from all other non-noble gas activities, together with the dose from any ground plane deposition which has occurred up to that point.
The EAL table only offers guidance to the operator as to the EAL detemination. The results listed are only part of the many example initiating conditions listed in the NUREG-0654 and the OCPP Emergency Procedure G-1 (Ref. 7). Accordingly, the operators judgemer; is still necessary as to the overall plant status to correctly identi)fy the EAL.
P.A.G. Table The Protective Action Guide (PAG) criteria used in the EARS programs are from table 5.1 of Reference 8.
They apply to the total dose (or dose commitment) projected for 'N' hours of persistent conditions from the update time. The criteria are:
1.
No action needed if Whole Body <1 ~ rem and Thyroid <5 rem.
2.
Sheltering recomended if Whole Body >= 1 rem and Whole Body <= 5 rem, or Thyroid >=5 rem and Thyroid <25 rem.
3.
Evacuation recomended if Whole Body >= 5 rem or Thyroid >= 25 rem.
The dose values which are cor:Dared to these criteria have two components:

Dose, either wnole body or thyroid, at each sector element centroid accumulated in all previous updates.
2.
Centerline plume exposure (including inhalation, but not ground plane) from a straight line plume from 'N' hours of persistence of current conditions, but not inclucing tne accitional cose from previously emitted plume segments.
The P.A.G. table showing the results of the comparision between calculated dose values and the criteria, is printed at the beginning of each projection and update. The protective actions for each sector are given for both Whole Body and Thyroid doses.
Projections and Vodates After the initial Basis for Release Rate, Source Term Values, Site Boundary Dase Calculations and Initial Accident Classification determination are given, more detailed calculations including a graphics display of plume dispersion and offsite class A dose estimates are presented.
(
It is possible to run up to five class A ' dose projections' and forty
.. },
t segmented Gaussian modeled, 'real-time' dose up-dates. A ' projection is made over a specified time period from release start time assuming no change in the initial release rate or dispersion condition.. A maximum of five projections are allowed, although none are required to proceed in the programs. It is generally best to limit the number of projections to one or two, of one to two hours each, due to the unrelia-bility of longer projections and the amount of time needed to run them.
An ' update' is a complete set of dose calculations initiated either from a CONTROL station by polling the HP-1000 for most recent real time MET data as in the EARAUT operation, or entering the most recent MET data via your HP-9845C keyboard as in the EARMAN operation.
Edge Dose Rate The edge dose rate is the plume exposure rate at the edge of the plume as displayed for the dose type (thyroid, whole body or lung) selected. This is displayed on the right-side of the CRT graphics area.
If The edge dose rate value chosen is greater than the plume center dose rate, message
" Edge dose rate > Centerline dose rate" is displayed. When a new edge dose rate is chosen, a plume with this new dose rate will be drawn. This is to prevent confusion regarding the parameters selected and the particular plume displayed.
The edge dose rate is always in mrem /hr. The default value in the EARS is.06 mrem /hr which corresponds to approximately 500 mrem /yr. It can be changed by pressing the EDGE DOSE TYPE / RATE soft key and entering a
(
new edge dose rate.

Whenever a new dose type is selected and a previous plume is already displayed, the new plume will be redrawn for the new dose type.
Radius and Plume Canter The talue displayed as '+ Radius' on the right-side of the CRT grapnics area is the minimum distance in meters frem the plume segment center (denoted by a small white cross on the graphics) to the edge of the plume for a given edge dose rate. This marker is used to indicate the ' centers' of the plume segments, starting fecm the earliest segment (generally the outermost. segment) to the latest segment (generally the innermost or closest to the site). The plume center-line dose rate is indicated in mrem /hr under the '+ Center Dose Rate' label on the right-side of the CRT graphics area.
Each time the STEP CENTER soft key is pressed, the white cross will move to the next plume segment center and the corresponding center-line dose rate and radius will change accordingly, cycling from the earliest segment to the latest.
(
Sector Element The dose rate, cumulative dose and cumulative deposition data are listed for each of 16 sectors in each of 5 ' sector elements'.
A sector element is an area bounded by a division of the compass into 16 sectors (from number 1 centered on North to number 16 on NNW) with radial distances as site boundary to 2 miles, 2 to 5 miles, 5 to 10 miles,10 to 15 miles, and 15 to 20 miles.
Data tabulated at the site boundary is calculated 800 meters from the site center in a given sector. Values for all other radial distances outside the site boundary are calculated at the mid-point of the range specified (the geometric center of a particular sector). Results will be printed as an asterisk if less than 10**(-10) mrem /hr.
Cumulative Deposition The cumulative deposition listed as Ci/m**2 of 'Cs-137 equivalents' is the quantity of Cs-137 which would yield a direct radiation exposure rate from ground plane deposition equal to the decay-corrected sum of all deposition which has occurred for that period. Due to large uncertainties involved in c.alculating both wet and dry deposition, this information is meant just to provide guidance to field survey teams as to where deposition is likely to have occurred. The values listed have relatively large uncertainties determining appropriate protective actions.

Succort EARS Software The function of the EARS support programs is to initialize, edit or review the EARS data files. These programs include EAREDT, EARSED, EARSDP, EAREVU, EARKSP, EARKDC and EARDOC, and are all stored on the HP-79C6 disc drive at tne stations. These programs are not nomally used during Emergency conditions.
EAREDT - Data File Edit Program The EAREDT program is used to setup, edit, or print the data files used by the EARS for system parametari, isotcpe specific parameters, FSAR release rate data, site boundary locations, fixed PIC locations, RMS parameters, This program can also duplicate from one nisus to another all of the etc.
data files used by the EARS.
The data files accessed by this program are ERDSYS, ERNCLS, ERNRMS, ERNMGR, ERDISO, ERNRPT, ERSNDY, ERPLCC, ERNMAP, ERDMET, ERNSTN, ER 7AP, ERDGRD and ERSTDC.
EARSED - Data String File Edit Program The EARSED program allows the operator "to access the data base to print, edit or initialite the projection and update string data stored on ERDSTA and ERDSTR, respectively. Rather than decoding the strings, this program edits or prints the ASCIIcharacters of the string for each of the parameters.
EARSDP - Calculational Parameters Plot Procram The EARSDP program allows the operator to print or plot coefficients used in calculating certain values for the EARS calculations. Data files accessed by this program are ERDSIG, ERDDEP and ERDIMR.
EAREVU - Updates Review Pecoram, The EAREVU program allows the operator to review the results of previous EARNAN or EARAUT runs. The operator can select any updates or projections previously run and stored on mass storage media for data printouts er plume plots.
EARKSP - Soft Key Functions Defining Progrim The EARXSP program is used to create and edit the soft key labels used in EARAUT, EARMAN, STATUS and ERAEVU programs. Labels for the soft keys are stored in a string array that is read from a data file on the program mass storage media (7906 disc cartridge).

TITLE EARS OPERATING PROCEDURES FOR TSC-CC HP-1000 STATION 3.
System Configuration The EAR system consists of a single HP-1000F mini-computer and 5 HP-9845C's placed at various strategic locations throughout the DCPP, San Luis Obispo County, and State. (See Figure 1).
Each HP-98t5C has an associated Logical Unit (LU) number and device number.
These numbers are used by the HP-1000 as addresses to aid in communicating with the peripheral HP-9845C stations.
The EARS /1000 programs are entitled EAR <N>K, where N is a number between 1 and 9 inclusive, which corresconds to the device number for each peripheral station connected to the HP-1000.
A transfer file AUT01 automatically starts up these programs at the time of " BOOT-UP". Should it become necessary to halt any or all of the EAR <N>K programs, they can be restarted by a "TR,AUT01" from the original copy of File Manage outside the Session Monitor frem the system console.

After a selection is made, the old value is displayed and EARED prompts the operator for a new value. Upon input of the replacement value, a verification is requested. A 'N0' response to any verification message during this phase will cause EARED to restart.
b.3 INITIALIZE OTABLE. This section leads the operator through a series of questions designed to set up DTABLE to the system manager's specifications.
The questions fall into two categories:
- 1) System parameters.
- 2) Station parameters.
After all questions are asked, the AUT01 transfer file is created and setup to clone and run all EAR <N>K programs from boot-up. DTABLE is also created and the header and all station records are configured according to the responses to the following prompts.
