The purpose of this procedure is to determine the radiological release status, meteorology, and the offsite dose consequences in the vicinity of ANO by use
- of the Gaseous Effluent Radiation Monitoring System (GERMS) computers.
2.0 SCOPE 2.1 This procadure is applicable to airborne radioactive releases from ANO, Units One and Two as indicated by the ventilation system stack monitors (i.e. the SPING monitors of the GERM System).
' 2.2 If the monitors are off scale, determine the release rates from 1904.03,
" Auxiliary Building Ventilation Exhaust Emergency Radiation Monitor".
2 2.3 This procedure does not take into account effects caused by precipi-
! tation.
l
} 2.4 To use the LFE Trapelo or Westinghouse effluent monito's, r (normal range monitors) determine the release rates from procedure 1904,04,
" Estimating Airborne Release Rates".
2.5 If releases are occurring from steam vents or from an unmonitored
(')
~'
release point, determine the release rates by procedure 1904.04,
" Estimating Ai'rborne Release Rates".

4 5.0 RESPONSIBILITIES a
5.1 The Shift Operations Supervisor is responsible for determining if an unplanned gaseous release to the environment is indicated by symptoms such as high stack monitor readings, area radiation monitor alarms or other indications.
1 5.2 The Duty Emergency Coordinator, or his designee, is responsible for i
performing the offsite dose projections until relieved and for sup-plying backup meteorological data and "unmonitored release" data to the GERMS computer as necessary throughout the incident.
5.3 The Shift Operations Supervisor / Duty Emergency Coordinator is re-
. sponsible for notifying appropriate groups per 1903.10, " Emergency Action Level Response".
5.4 The Offsite Radiological Monitoring Section of the Emergency Radia-tion Team is responsible for measuring offsite radiological hazards
(~ per 1903.43, " Duties of the Emergency Radiation Team".
5.5 When the Technical Support Center is manned, responsibility for track-ing offsite doses, gathering forecasts, and making protective action recommendations will transfer to the Technical Analysis Superinten-dent. At this time, the Shift Operationc Supervisor / Duty Emergency Coordinator should turn over all paperwork generated under this pro-cedure to the Technical Analysis Superintendent.
i 5.6 When the Emergency Control Center is manned, responsibility for tracking offsite doses, gathering forecasts, and making protective action recommendations will transfer to the ERO Dose Assessment' Supervisor. At this time, the Technical Analysis Superintendent 1
may turn over all paperwork generated under this procedure to the Dose Assessment Supervisor. The plant staff will continue to monitor the operation of GERMS computers and provide technical assistance to the ERO staff as needed (i.e. in case of computer malfunction).
- 6.0 LIMITS AND PRECAUTIONS 6.1 The Chromatics terminals in the ANO-1 and ANO-2 Control Rooms are connected to separate redundant report-generating computers. Data l for the entire site is available from either computer. In addition,
, a malfunction on one computer will generally not affect operation of '
the other. This requires that to maintain redundancy, hand entries ;
, .. of "unmonitored" releases or missing met data must be made on both i systems if they are both operating. '

- 6.2 This procedure describes only limited routine and emergency use of
- the GERHS computers. A wide range of additional capabilities are
! available. However, the occasional user should not attempt to use
}
programs and commands which are not specifically described in this procedure.
4 l 6.3 This procedure provides a projection of ti? radiological conditions based upon measured release rates and meteorology; field monitoring is necessary to determine the actual conditions.
f 6.4 Actual terrain and weather conditions will generally limit the ac-
! curacy of the projected doses at a specific location.
t 6.5 The light pen attached to the Chromatics computer terminals may be damaged if dropped or subjected to rough use. Never press the end of the light pen hard against the face of the Chromatics screen.
!, In most cases, no direct contact is required to select options.
l Never attempt to unscrew the light pen barrel. Operability of the light pen is required to complete this procedure.
6.6 The Chromatics color graphic terminals located in the ANO-1 and ANO-2 control :.coms should normally be left with power on to both the termi-
. nal and its associated disk drive, an EDC processing diskette in the
(}.j disk drive, and User 44 assigned.
6.7 If errors occur, or if the computers or tenninals do not function properly, refer to section 17.0, " ERROR RECOVERY".
6.8 The occasional user should not attempt to sign-on user numbers which are not specifically authorized by this procedure. Disruption of automatic programs or the loss of important data may result.
a 6.9 Data shown on the GERMS offsite dose maps will typically be 30 min-
, utes old when they are first produced. If high releases occur very 3 suddenly, it would be advisable to calculate the first plume segment i using Procedure 1904.02.
1 a 6.10 When releases have been in progress for more than 5\ hours, historical
! plume segments will be periodically " compressed". This may result in i noticeable changes in the plume display and the tabulated data.
j 6.11 The Emergency Dose Calculation (EDC) jcbstreams are assigned to GERHS j computer user 44. This user must be signed on the Control Room Chro-
'; matics terminals to allow operator prompts, inputs, and automatic re-j port generation.
I NOTE: Each Control Room terminal. will be addressing a different GERMS computer.

! 13.0 NOTIFICATIONS AND PRCTECTIVE ACTION RECOMMENDATIONS
~
6 13.1 If an Unusual Event, Alert, or Site Emergency has been declared, pro-
) ceed directly to Section 13.2. If a General Emergency has been de-clared, make the following recommendation to the Arkansas Department of Health:
13.1.1 As a minimum, recommend sheltering within a 2-mile radius of the plant and 5 miles in the downwind direction.
13.1.2 In order to select the appropriate protective action', State g officials should be given an estimate of the expected release J duration. This is especially important if the release dura-
- tien is expected to be less than 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> (puff releases).
I 13.1.3 Upon activation of the TSC/ECC, additional protective action recommendations should be evaluated using procedure 1904.07,
.i " Protective Action Recommendations". These evaluations,
, should be made under the supervision of the Technical Analy-sis Superintendent and/or the Dose Assessment Supervisor.
13.2 Provide radiological release information to appropriate groups per 1903.10, Emergency Action Level Response".
13.3 If a photograph of current offsite conditions has been requested, the TSC/ECC staff should refer to Section 19.0 of this procedure.
13.1 The Emergency Radiation Team shall be dispatched to obtain field ra-diclogical data whencver any Emeegency Action Level has been declared I bared on offsite radiological releases. When the field monitoring teams report maximum (centar1Lnci dose rates at various downwind ,
distances, the TSC/ECC staff should refer to Secticn 18.0. j
. 13.5 Use the light pen to select the " Return to Midas" circle on the Chrunatics screen, then type " QUIT [F.E"NRH]" at the terminal key-board.
NOTE: Returning to Midas, then restarting the display program (Steps !
10.1 through 10.5) is the fastest way to advance through several updates in order to observe current conditions.
13.6 Request that the plant Radiochemistry staff sample the air effluent from the plant ven,ts and analyze the spectrum of radioactive isotopes being released. When this data becomes available, the TSC/ECC staff should complete Section 16.0 of this procedure. i e
1 13.7 A qualitative change in the data received from any of the meteorologi- l cal, flow rate, or radiation monitoring sensors will result in the _l listing of a status change report on the control room Chromatics or a printing terminal. If this has occurred, refer to Section 23.0 of this procedure.

i 1 NOTE: The mid-range and high-range noble gas channels of the SPING monitors
- indicate dose - equivalent Ke-133 concentrations. When the indicated neble gas activity in any duct monitored by a SPING exceeds approxi-mately SE-2 pei/cc as Xe-133, then more accurate dose calculations lj will result if the noble gas distribution for this duct contains only l
- Xe-133. For lower concentrations or for unmonitored pathways, use of l
i the actual isotopic analysis is preferable.
16.1 The release rate distributions for a release pathway should be changed ll; l
whenever new laboratory data is obtained detailing the relative con-j centrations of isotopes being discharged via that pathway.

- tems below. More complex problems should be refered to the Assistant Radiochemistry Supervisor in the OSC when he arrives onsite. If in-surmountable problems occur, use procedure 1904.02 to perform manual offsite dose calculations.
17.1 Mis-Typed Keyboard Entry 9
l 17.1.1 If the Chromatics terminal is in color graphics mode (i.e.
1 color display), the back-arrow key will back the cursor
- destructively over previously entered characters. All
,; characters at or to the right of the cursor location are erased in memory, although they remain on the screen.
17.1.2 If the program is running on the GERMS computers, individual characters may be deleted by simultaneously pressing "[ CTRL]
[ SHIFT]O" or the entire line may be deleted by simultaneously pressing "[ CTRL][ SHIFT]/".
17.2 Light-Pen Does Not Work
(,r.s s-17.2.1 It is possible for the light pen to become overloaded by the strong electromagnetic fields near the Chromatics termi-
, nal screen. Waiting 30-60 seconds will usually restore operability.
- 17.2.2 Gently wiggling the olack tip of the light pen from side to side will often restore operability (a flash of blue j light should be seen on the screen).
17.2.3 If the program running in the Chromatics ttrminal halts, the light pen will step respending Hit the [ BREAK] key.
i If a " Break in Line..." message appears where "..." repre-sents one of the program line numbers, then the light pen is probably defective and should be replaced. Otherwise, the terminal program has halted (see Section 17.3.1 to restart the terminal).
17.3 No Response to Keyboard Entries a
NOTE: The automatic' processing programs are designed to restart them-selves, even if they are halted to clear other program / hardware errors.

- NOTE: The computer model can be adjusted to make the projected offsite
- dose rates agree with measured dose rates by changing the "re-circulation factors" to values other than 1.0. These factors are used within the model to multiply the projected concentra-
', tions, doses, and dose rates before they are recorded and dis-played. If the Assistant Radiochemistry Supervisor is onsite, he should be asked to perform these adjustments.

It is designed to repetitively display the most re-cent meterological and RMS data in the Control Rooms during routine operations so that data collection failures may be quickly identified and reported. The " AUTO.0PCHEK" jobstream is automatically aborted if any of the SPING detectors registers a high radiation alarm. 3 21.1 From the Chromatics terminal in either Control Room, type "WHO
, [ RETURN]". If any user other than User 44 is currently assigned, type " BYE N_N{ RETURN]", where NN is the current user. Then type "HEL 44[ RETURN]", and "U44[ RETURN] _". The message " CAUTION - USER PROGRAM OR JOBSTREAM ACTIVE" should appear.
_ 21.2 Type " JOB AUTO.0PCHEK,,, TTY [ RETURN]" to start the status-reporting (# 4 jobstream. If the error, "US.:R ALREADY SIGNED ON" occurs, type
" DIS [ RETURN]" and copy down the name of the jobstreams and programs currently assigned. Request help from the Assistant Radiochemistry Supervisor as needed.
21.3 GERMS status information will begin scrolling up the screen. To stop the scrolling, hold down the [ CTRL] key and type the letter "T". Re-peat this to restore terminal operability and restart the scrolling. 21.4 When the " DIS" command is executed, a listing of the fundamental com-puter parameters, including the percentage of computer free time, the R amount of free memory, and the status of the task processor will be 1 displayed. The amount of free memory should be at least 100,000 words, and the number of disk errors should be zero. 21.5 When the "WHO ALL" command is executed, a listing of all users cur-rently active on the computer will appear. User numbers 42 through t 47 plus 49 should be present.
' 21.6 Two programs, APS.EDCTIM and APS.EDCDAT, will run primarily to select and format data for the remaining two, APS.EDCEMD and APS. VENT.
APS.EDCTIM selects and displays the time (" DATA DATE") of the most l
, recent entry in the continuous monitor, or raw data, file (CMF).
APS.EDCDAT periodically checks this CMF entry and waits until all available data have been transferred to it, or a maximum of three - , minutes. l

{ 21.7 When APS. VENT is run, a listing of the concentrations, flow rates, l and total particulate, iodine, and noblehgas release rates for each of the ten monitored gaseous discharge paths will appear. Release paths which are known to be "in service" should have reasonable flow rate and concentration data (i.e. not " BAD" or " MISSING") . The l SPINGS which correspond to "out of service" release paths should be I in the " STANDBY" mode, so their flow rates and concentrations should l all be listed as " MISSING". " BAD" data indicates failed or misad-
, justed sensors, or channels which are undergoing maintenance or cali- , bration. . / 21.8 The release rates for the "unmonitored pathway" will also be listed.
[ These release rates should be zero and the "unmonitored" flow rate
, should be 2119 CFM. The flow rate functions as a units conversion factor in this case, and should not be changed.
!. 21.9 When APS.EDCEMD is run, the current meterological data should appear 3 on the screen. If wind speed, wind direction, sigma theta, or tem-
, perature gradient information is not available, the operator will be warned and the program will request that correct data be entered. A single carriage return is sufficient at this time. I" none of the meteorological data was received from the meteorolog. cal tower, the

l 23.0 ADJUSTHENTS TO THE UNHONITORED PATHWAY RELEASE RATES
- l NOTE: When any of the SPING radiation or flow channels changes status 3' from " good" to " bad / missing", a release path which was previously monitored has potentially become unmonitored. By printing a status change report, the GERMS computer requests the operator
; to acknowledge the loss of data. If the loss of monitor data was not accompanied by the physical shutdown of the release
~
point, the operator should add the release point data to the site total unmonitored release rates. Activity must be sub-tracted from the site total unmonitored release rates when a { channel changes status from " bad / missing" to " good". i 23.1 Record the " current" and " previous" data from the status change re-port for each channel which has changed state on Form 1904.01A. In
, case the screen has been cleared, typing "3[ RETURN]" will relist the )
q report. I i 23.2 Copy the summary information from the lower portion of the status change report to Form 1904.01A. 23.3 If the indicated status changes all correspond to the physical shut-
^
down/startup of the associated release path, selection of option 1
'*. (PROCEED) is the only response that is required. If any of the listed status changes are independent of the status of the associated
, release paths, proceed with Section 23.4.
NOTE: SPINGS monitoring non-operating release paths should be placed in the " standby" mode at this time. Refer to Step 8.4.2 for the procedure to do this. l 23.4 If the absolute value of any of the "% CHANGE" values on Fcrm 1004.01A J exceeds 25%, select option 2 (SKIP) to postpone the calculation of offsite doses. Otherwise, enter option 1 (PROCEED). S 23.5 Adjust the site total unmonitored release rates as follows: 7.- 1 A. If a channel has gone from " Good" status (i.e., some numerical value) to " Bad" or " Missing", use the " previous" flow or concen-tration to calculate a correspcnding increase in the unmonitored release rates for this pathway un Form 1904.01B. Note the sum-
; mary time as the " Time Last Measured" on the form.
, B. For data which has gone from " Bad" or " Missing" status to " Good",
record a zero in the appropriate line and column of Form 1904.01B. Note the summary time as the " Time Last Measured". C. Transfer the remaining unmonitored release rates from the pre- -

ARKANSAS NUCLEAR ONE ><visma e CHANGE sare ve< u '/ ** DATE 1.0 PURPOSE j i The purpose of this procedure is to provide an initial estimate of the radiological conditions at the ANO Exclusion Area Boundary, provide in-formation to determine the Emergency Action Level, define the offsite area (s) potentially affected by an airborne radiological release, provide an estimate of the whole body and child thyroid dose rates and refine pro-jections based on available field monitoring data, using a hand-held com-puter to perform the necessary calculations. 2.0 SCOPE a 2.1 This procedure is applicable to airborne radioactive releases from
' ANO, Units One and Two as indicated by the ventilation system stack monitors (i.e. the SPING monitors of the GERM System).
j 2.2 If the monitors are off scale, refer to 1904.03, " Auxiliary Building ventilation Exhaust Emergency Radiation Monitor". 1 2.3 This procedure does not take into account effects caused by precipi-tation. l 2.4 To use the LFE Trapelo or Westinghouse effluent monitors, (normal
' k- r) range monitors) refer to procedure 1904.04 " Estimating Airborne Release Rates".
2.5 If releases are occurring from steam vents or from an unmonitored re-lease point, determine the release rates by procedure 1904.04, "Esti-
, mating Airborne Release Rates".

The correctly scaled overlays and maps are located in the emergency kits. 10.1 Select the overlay (Attachments 1-7) which corresponds to the existing atmospheric stability category (Form 1904.02A). 10.2 Place the selected overlay on the ANO area map (Attachment 8) with .,' the origin directly over the ANO site center and align the plume cen-terline with the downwind direction (from Form 1904.02A). 10.3 To locate the plume boundry line on the overlay, obtain the plume bounding X/Q from Form 1904.02A Section 4.0 and determine its location on the appropriate overlay. If the bounding X/Q falls between two existing X/Q lines on the overlay, select the outward of the two lines as the a plume boundry. Any sub-sectors which are contained (or partially contained) with the plume boundary line should be designated as af-fected. Record this information on Section 6.0 of Form 1904.02A. 10.3.1 Account for the uncertainty in the local wind near Mt. Nebo/
, Spring Mountains
_s A. If the plume centerline lies in sector 10 and the plume boundary extends beyond 6 miles, the affected area
. should also include sectors 9, 10 and 11 (from sub-sector G to the projected extent of the plume).
B. If the plume centerline lies in sector 11 and the plume boundary extends beyond 6 miles, the affected area should also include sectors 10, 11 and 12 (from sub-sector G to the projected extent of the plume). 11.0 NOTIFICATIONS AND PROTECTIVE ACTION RECOMMENDATIONS 11.1 If an Unusual Event, Alert, or Site Emergency has been declared, pro-l ceed directly to Section 11.2. If a General Emergency has been'de-clared, make the following recommendation to the Arkansas Department of
, Health:
11.1.1 As a minimum, recommend sheltering within a 2-mile radius of the plant and 5 miles in the downwind direction. 11.1.2 In order to select the appropriate protective action, State ) officials should be given an estimate of the expected re-lease duration. This is especially important if the re- ) lease duration is expected to be less than 2 hours (puff _
~
releases). l

8.1 The Auxiliary Building Ventilation Exhaust Stack Radiation Monitor System consists of an isokinetic probe installed in the exhaust j stack (1 per unit), necessary piping (3/4") to the sampling station, valving, a silver zeolite cartridge (for iodine absorption) and a i particulate filter, a sample bomb (for noble gas analysis), pump, flow indicator and a radiation monitor (Model RMS II, range of 0.1 to 10,000 mR/hr). 3 8.2 The radiation monitor (Model RMS II) consists of a detector.which is P located external to the sample piping on Elev. 404 between Unit I and Unit 2 in the Spent Fuel Pool (SFP) Area and a remote readout located j) in the Unit I control Room. Normal power,110 VAC, is supplied to
- { the monitor and the pump from a wall outlet located in the Unit I
'5 Control Room next to the monitor. Backup power may be supplied by j a vital buss in the Unit 2 Control Room. The use of an extension cord is necessary if power is to be provided from Unit 2. The extension cord consists of 100 feet of cable with 1 male plug on the end con-necting to the vital buss connector in the Unit 2 Control Room and 2 fe-
; male plugs to connect the monitor and the pump in the Unit 1 Control Room.
.; This cord is located in the emergency kit located in front of the monitor located in the back of the Unit I Control Room. - NOTE: See Attachment 3 for locations of the above items. v-- , , _ , e a e 9

NOTE: Normal monitoring is accomplished by sending vent flow
; through an empty sample cartridge. Periodically vent flow is passed through a cartridge containing a particu-late filter and a silver zeolite cartridge loaded in series in the cartridge.
1 9.1.2 Load particulate filter and silver zeolite cartridge into FAl (filter assembly located between V3.and V5). 4 9.1.3 Select unit exhaust to be sampled and/or monitored. A. If Unit 1, open VIA and V7A.
. B. If Unit 2, open VlB and V7B.
L:s 9.1.4 Open inlet valve to empty filter assembly (V2). Open out-let' valve to empty filter assembly (V4). Open V8, V6 and' V9. 9.1.5 Start pump. Throttle V6 and, if necessary, V8 to maintain flow at ~2 CFM. 9.1.6 Log start time on Form 1904.03B. 9.1.7 Continue taking readings per Section 9.5.
.e 9.2 Sample Collection of Particulate Filter and Silver Zeolite Cartridge 9.2.1 Verify that the system is lined-up and operating per Sec-
- > tion 9.1.
9.2.2 Verify that a particulate filter and silver zeolite cart-
; ridge are in the loaded filter assembly and open the out-let valve. If the assembly is not loaded, load the assem- ,; bly and then open the outlet valve.
9.2.3 Simultaneously open the inlet valve on the loaded assembly while closing the inlet valve on the empty assembly (ex. V3 on FA1 should be open while V2 on FA2 should be closed). m I li t _

I 9' ARKANSAS NUCLEAR ONE CHANGE DATE 1.0 PURPOSE
- This procedure provides a manual method for estimating the location of airborne radioactive materials offsite under changing release and meteo-rological conditions, and for estimating the maximum integrated dose com-mitments at 0.65, 2.0, 5.0, and 10.0 mile radii.
. 2.0 SCOPE
; 2 .1" This procedure is applicable to airborne radioactive releases from either ANO-1 or ANO-2.
d
; 2.2 This procedure does not calculate the fine structure (actual distri-bution) of integrated doses offsite.
2.3 This procedure does not take into account effects caused by precipi-tation and terrain channelling. 2.4 The data generated from this procedure is used as input for procedure 1904.07, " Protective Action Recommendations" and no notifications are - required.

,i j 4.2 The Duty Emergency Coordinator, or his designee, should initiate i radiological plume tracking and dose integration as soon as possi- ? ble after the TSC is activated and continue until relieved by the .. Dose Assessment Supervisor.
5.0 LIMITS AND PRECAUTIONS
- 5.1 Actual integrated doses will generally be lower than predicted by this procedure due to typical wind direction meander.
5.2 In order to be meaningful, the dose integration must cover the entire
]a release period (i.e. all plume segnents).
, 5.3 If dose calculations were made during the initial portion of a radio-active release incident using the GERMS computers, and these compu-
; ters are no longer available, perform procedure Section 12.0 one time to convert the GERMS output into hand-calculation format.
' 6.0 DEFINITIONS 6.1 Plume Segment - An air parcel containing radioactive material emitted
, at a relatively uniform release rate and under relatively uniform meteorological conditions.
7.0 DOSE RATE PROJECTION
SUMMARY
7.1 Transfer the dose projection input and output data from Form 1904.02A to Form 1904.06A for each dose projection as it is performed, i.e.
. therefore the oldest data will appear closer to the top of the form.
Include all dose projections previously calculated by Control Room personnel since the beginning of the release. The time on Form j 1904.06A refers to the time recorded on 1904.02A. 1 7.2 For each projection, compute the " segment length (miles)" by multi-j' plying the then-current windspeed (mph) by the total elasped time between the current and previous data collection times (hours). Re-d cord the " segment length" on Form 1904.06A for each dose projection (plume segment). NOTE: The elasped time for the first plume segment is the time period
! from the stat t of the release to the first data collection time.
7.3 Combine sequential doce projections which have similar meteorological
; and release rate characteristics into a single plume segment. This
' reduces subsequent plotting and integration tasks.

- 8.0 PLUME CENTERLINE PLOTTING
.J 8.1 Obtain a 360' protractor, ruler, stability class overlays, map, cal-culator, and pad of tracing paper (11" x 17", ruled 10 x 10 to the inch) from the appropriate emergency kit:
8.1.1 Technical Support Center 8.1.2 Emergency Control Center 8.2 Select an origin and north-south axis on the tracing paper, taking
?
into consideration the general direction of plume development.
}
1 8.3 Refer to Form 1904.06A to determine the downwind direction and seg-ment length of the most recently emitted plume segment. J i 8.4 Center the protractor on the origin of the tracing paper. 8.5 Turn the protractor imril the downwind direction angle (indicated on the outer ring) is aligned with either 'the north or the south direc-O tion on the tracing paper. t 8.6 Draw the segment centerline along the indicated side of the protrac-
.j tor's central straightedge, depending on whether the downwind angle J was aligned with north or south on the paper.
I 8.7 Use a ruler to draw the plume segment length to scale (l" = 1 mile). I 2 8.8 Mark the segment endpoint. This is the starting point for the next (older) plume segment. !

; segment starting point on the centerline of the stability i overlay.
.. 9.1.3 Place the overlay under the tracing paper bearing the cen-
; terline plot, aligning the segment starting points and centerlines.
9.1.4 Trace the bounding X/Q lines for the segment, connecting smoothly with the adjacent segment. (It is usually helpful
. to extend the boundary lines an inch or so beyond the seg-ment endpoint).
9.2 Darken the plume outline. 9.3 Affix the tracing sheet to a 10-mile radius emergency planning map, aligning the north-south directions, and centering the starting point of the youngest plume segment over the plant site. Carbon paper may be used to transfer the plume centerline and outline to multiple emergency planning maps, if necessary.
,, 10.0 DOSE COMMITMENT INTEGRATION c'~I 10.1 At the top, leftmost open column on each page of Form 1904.06B, list the starting and ending times for the earliest segment not previously' listed.
10.2 Subtract the starting time from the ending time to determine the
' duration of this integration period in hours.
,' NOTE: A separate set of forms must be maintained for whole body and
, for child thyroid doses.
I 10.3 Compare the plume centerline plotted in Section 8.0 with the dose j projection summary on Form 1904.06A. Determine which set of dose projection data on 1904.06A applies to the portion of the plume currently crossing the 0.65 mile map radius. Copy the mR/hr dose
, rates (child thyroid and whole body) to page 1 of Form 1904.06B.
- , Each dose rate should be recorded on the line on 1904.06B which corresponds to the map sector where the intersection occurs.
l NOTE: If portions of the plume were previously drawn by the GERMS com-puters. there will be no centerline data for them on Form t 1904.06A. Interpolate among the field dose rates reported by
, the Offsite Monitoring Supervisor.
, 10.4 Multiply the dose rates obtained in Step 10.3 times the duration of i , , the integration period to determine the incremental whole body and
~
child thyroid integrated doses. Record these in the ' A' Dose column on the whole body and child thyroid worksheets (Form 1904.06B), on the appropriate sector / radius line. i S e

NOTE: When the plume centerline falls between two sectors, add the j incremental doses to both sectors. 10.5 For each sector / radius line on Form 1904.06B, add the entry in the
, current 'A' Dose column to the entry in the previous 'I' Dose column and record the new total integrated dose in the current 'I' Dose column. This will result in a running total being generated from left to right across the page.
3 NOTE: The integrated doses at all offsite locations are assumed to be zero prior to an incident; therefore, the first 'I' Dose column fi of an incident will equal the first 'A' Dose column.

indicate that: 11.1.1 Whole body integrated dose may approach 1 R (1000 mR), or
. 11.1.2 Child thyroid integrated dose may approach 5 R (5000 mR) in accordance with procedure 1903.32.
11.2 Recommend protective action in affected onsite (exclusion area) sub-sectors when whole body dose rate exceeds 2.5 mR/hr in accordance a with procedure 1903.31.

For this reason, users should know clearly what information is required before signing-on and should also sign-off promptly when the required information has been listed. 6.2 Weather Services International (WSI) collects weather information on a continuous, round-the-clock basis from weather stations located throughout the world. High-speed data links allow WSI to receive most of the U.S. hourly data within 10 minutes of the observation time. 6.3 A wide variety of additional data is available from the WSI service. However, the casual user is discouraged from experimenting with com-mands which are not explicitly described in this procedure. 6.4 Always wait until the "+" prompt appears before entering additional commands when you are logged in to the WSI service. 7.0 SPECIAL KEYBOARD COMMANDS 7.1 (CTRL] CC [ CTRL) and C, then C again to " clear" the terminal. [ CTRL) CC is the WSI panic button and will stop any program at any time. The + prompt will appear to indicate that you may enter a new command. 7.2 [ DELETE] Press [ DELETE] (on some terminals, this key is labeled (DEL) or [RUBOUT). The (BACKSPACE] key will also perform the same function) to delete characters one at a time starting with the most recently typed character. For TELENET users, a backslash (\) will appear and the characters extinguished will show after the slash. For TYMNET, the characters de-leted will be repeated, and the slash will not appear. O N 9

l CHANGE DATE 11.4 The second " wind" column contains four-digit numbers. The first two digits represent the wind direction rounded to the nearest ten degrees and divided by ten. The second two digits are the windspeed in knots. The wind direction for the adjacent reporting stations may usually be averaged for dose assessment work, unless they are radically different, in which case selection should be based on estimated current condi-tions. (Remember that O' and 360' both refer to north.) 11.5 The "GST" column is the maximum wind gusts reported, in NPH. 11.6 The "PS" column contains the Pasquill Stability Class at the reporting station. The stability class which exists at the largest number of the adjacent reporting stations may be used for dose assessment work. 11.7 The " sky" column contains a literal description of each cloud layer l preceded by its height in hundreds of feet. When necessary for use in dose assessment procedures, onsite cloud conditions may be taken to be the most frequently occurring condition from the adjacent re-porting stations. The letter "C" denotes the aviation ceiling, if l any. NOTE: The first column indicates the lowest cloud layer in hundreds of feet. Under stable dispersion conditions, this may be inter-preted as the limit of vertical dispersion (mixing height). 11.8 The remaining columns are the surface temperature (*F), dew point ('F), relative humidity (%), barometric pressure (millibars times 10 minus 900 or 1000) and the three hour pressure change (millibars times 10). NOTE: To convert the tabulated barometric pressure to millibars, divide by 10. If the resulting value is greater than 50.0, add 900. If it is less than 50.0, add 1000. (The normal surface pressure ranges between 960 and 1050 millibars.) 12.0 FORECAST DATA 12.1 Type " Zones AR [ Return]". A listing of statewide weather forecasts will appear, by forecasting zone. (See Attachment 2 for an example - a map of Arkansas forecast zones is included as Figure 1). 12.2 The forecast for the counties west and east of Russellville are listed under " ZONE 4" and " Zone 5" respectively. If these :enes are not specifically listed, type " Zones AR #2 [ Return]" to list the previous forecast. 12.3 Type " STATE AR (RETURN]". A single sta~tewide forecast will appear, followed by an extended (5-day) forecast. This extended forecast may contain information useful for longer-range emergency planning.
