; iia /R2 1.0 PURPOSE NOTE: This procedure provides a computer approach to the calculations described in 1904.02, " Magnitude of Release - Unit 1."
The purpose of this procedure is to provide an initial estimate of the radio-logical conditions at the ANO Exclusion Area Boundary, provide information to determine the Emergency Action Level, define the offsite area (s) poten-tially affected by an airborne radiological release, provide an estimate of the whole body and child thyroid dose rates and refine projections based on available field monitoring data using a computer to perform the necessary calculations. 2.0 SCOPE 2.1 This procedure is applicable to airborne radioactive releases from ANO, Unit One as indicated by normal ventilation system stack monitors; if the monitors are off scale, refer to 1904.03, " Auxiliary Building Ventilation Exhaust Emergency Radiation Monitor". 2.2 This procedure does not take into account effects caused by precipi-
,._ tation.

5.2 The Duty Emergency Coordinator, or his designee, is responsible for performing the magnitude of release calculations. 5.3 The Duty Emergency Coordinator is responsible for notifying appro-priate groups per 1903.10, " Emergency Action Level Response". 5.4 The Offsite Radiological Monitoring Section of the Emergency Radia-tion Team is responsible for determining of fsite radiological hazards per 1903.43, " Duties of the Emergency Radiation Team". 6.0 LIMITS AND PRECAUTIONS 6.1 This procedure provides an initial projection of the radiological conditions; field monitoring is necessary to determine the actual conditions. 6.2 Conversion factors which are provided to establish the child thyroid iodine dose rate are based on design basis accidents and should be considered less reliable than the calculated whole body dose rate. 6.3 Actual terrain and weather conditions will generally limit the ac-curacy of the projected doses at a specific location. (_
\' l 6.4 The diffusion overlays used in this procedure represent long-term average conditions for a ground level release.
6.5 The computer display is made of glass. Special care should be ex-ercised to prevent dropping, bending, etc., this device. 6.6 When performing manual or programmed calculations, the computer should be in the RUN Mode. 6.7 When you enter numbers, characters, and instructions into the Computer (via the keyboard) this data is stored but it is not executed until you press the [ ENTER] key. 6.8 The REM plug must be removed in order to operate the Fast-Forward and Rewind functions on the cassette tape recorder. 6.9 The tape heads and tape handling parts snould be kept clean - use a cassette cleaner /demagnetizer tape, if possible. 6.10 Volume level can be very important when reading in data from the reco.irr; make slight adjustments when required to obtain the proper data t ansfer. 6.11 Be sure the connections between the Pocket Computer, Cassette Interface, r"~N and Recorder are secure and dirt-free. U 6.12 If problems occur when using AC power for the recorder, use battery power instead (sometimes the AC power connection also adds some " hum" to the signal which upsets proper digital recordings). _; ,4

The scaled overlays and maps necessary to do the actual calculations with are located in the emergency kits. 10.1 Select the overlay (Attachments 1-7) which corresponds to the exist-ing atmospheric stability category (Form 1904.01B, Line 1.2).
,._ 10.2 Place the selected overlay on the ANO area map (Attachment 8) with
(
\~ /
i the origin directly over the ANO site center and align plume center-line with the downwind direction. NOTE: The maximum downwind extent of the affected area may also be de-termined by the projected extent of the plume boundary. 10.3 Locate the general vicinity of the plume Soundary (from Form 1904.01D Line 5.1.3) on the overlay corresponding to the Atmospheric Stability Category. 10.3.1 Any sectors which are contained (or partially contained) within the plume boundary line should be designated as an affected area. Record this information on line 7.0 of Form 1904.01D. NOTE: The following steps account for the uacertainty in the local wind direction caused by the Mt. Nebo/ Spring Moun-tain terrain features. 10.3.2 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 subsector G to the projected extent of the plume). 10.3.3 If the plume centerline lies in sector 11 and the plume boundary extends beyond 6 miles, the affected area should 7~) \# also include sectors 107 11 and 12 (from subsector G to the projected extent of the plume). 10.4 If it is necessary to calculate plume arrival time (in hours) for a, specific location, divide the distance (in miles) from the plant to .jj .& the location by the windspeed (in mph). ,.

They shall be dispatched upon declaration of a Site Emergency. If the Emergency Radiation Team is dispatched, re-fer to Section 12.0. 11.3 Return to Section 7.0 ot this procedure (or section 7.0 of 1904.04,
" Magnitude of Release - GERMS," if SPING data is being used). New data should be taken as specified by the Duty Emergency Coordinator / Dose Assessment Supervisor.
NOTE: This section may be used during periods that monitoring teams have been dispatched, to improve dose projections based upon the comparison of projected and measured whole body dose rates (S at field locations on the plume centerline. This section is ( ,j designed to complement rather than replace the ongoing dose projections of Sections 7.0 through 10.0. 12.0 VERIFICATION OF PROJECTED DOSE RATES BY FIELD MEASUREMENT 12.1 Based on wind direction, the Duty Emergency Coordinator /Offsite Monitor-ing Supervisor should dispatch offsite radiological monitoring teams to sample the plume at the appropriate locations to be specified at the time of the incident. Preselected survey points in each sector and zone are shown on the area map (Attachment 8). 12.2 The radiation survey at each location should include a direct exposure rate measurement (mR/hr) and an air sample to determine iodine concen-tration (pCi/cc). As the survey teams approach the assigned survey location, continuous radiation measurements should be taken to identi-fy the location of the highest radiation level. As survey results are obtained, the radiological monitoring team should report the results to the Duty Emergency Coordinator /Offsitt Monitoring Supervisor and proceed as directed. NOTE: Real-time determinations should be compared to projected levels for corresponding time pericds. 12.3 Determination of Iodine Dose Factor by Field Measurement. 12.3.1 Record on Form 1904.01E, the appropriate Field Location in Column 1, the Iodine Concentration in Column 2, and Whole Body (N Dose Rate in Column 3.
'"J 12.3.2 Calculate the Iodine Dose Factor for each field location in Column 4. (The most recent calculated Iodine Dose Fac-tor may be used for future Child Thyroid Dose Projections.)

12.4 Determination of Whole Body Overlay Scale Factor ' 12.4.1 Scale factors may be determined to refine future whole , body dose estimates based upon field measurements. Because ' the dose rate may change rapidly with distance from the plume centerline, scale factors should be based only upon a comparison of a projected plume centerline dose rate with the highest measured field dose rate determined by traversing the plume at the projected downwind distance. This ensures that the projected plume centerline dose rate is compared with the actual plume centerline dose rate. 12.4.2 If a projected Whole Body Dose Rate has been determined (Form 1904.01D) for a plume centerline location, record the Whole Body Dose Rate in Column 5. 12.4.3 Calculate the ratio of the Measured Dose Rate to the Pro-jected Dose Rate and record in Column 6 of Form 1904.01E. 12.4.4 The most recent calculated ratios may be used for future Whole Body Dose Rate Projections.
