(N 3 ) 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. l 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. l l 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 should 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 recorder; make slight adjustments when required to obtain the proper data transfer. 6.11 Be sure the connections between the Pocket Computer, Cassette Interface, and Recorder are secure and dirt-free. O(_,/ 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).

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 (Attschment 8) with the origin directly over the ANO site center and align plume center-s ( ) line with the downwind direction. { x- / j NOTE: The maximum downwind cxtent of the affected area may also be de- { termined by the projected e,xtent of the plume. boundary. i 10.3 Locate the general vicinity of the plume boundary (from Form 1904.01D Line 5.1.3) on the overlay corresponding to the Atmospheric Stability l Category. l 10.3.1 Any sectors which are contained (or partially contained) l within the plume boundary line should be designated as an a f fected area. Record this information on xline 7.0 of Form 1904.01D. NOTE: The following steps account for the uncertainty in the local wind direction caused by the Mt. Nebo/ Spring Moun-tain terrain features. 10.3.2 If the plume centerline lies 12 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 also include sectors 10, 11 and 12 (from subsector G to the (O) 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 the location by the windspeed'(in mph). - _ _ _ _ _ - _ _ _. _ - - _ _ ~ -

T .11.2 The Emergency Radiation Team may be dispatched to obtain field radio- ] ' logical data at the discretion of the Duty Emergency Coordinator / Recovery Manager. They shall be dispatched upon declaration of a Site Emergency. If the Emergency Radiation Team is dispatched, re-fer to Section 12.0. 1 J-11.3 Return to Section 7.0. New data should be taken as specified by the Duty Errergency Coordinator / Dose Assessment Supervisor. NOTE: Tnis section may be used during periods that monitoring teams have been dispatched, to improve dose projections based upon 9_ the comparison of projected and measured whole body dose rates at field locations on the plume centerline. This section is designed to complement rather than replace the ongoing dose { e projections of Sections 7.0 through 10.0. J 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 a rate measurement. (mR/hr) and an air sample to determine iodine concen-tration (pCi/cc). As the survey teams approach the assigned survey g 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 /Of fsite Monitoring Supervisor and proceed as directed. NOTE: Real-time determinations should be compared to projected levels for corresponding time periods. 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 Dose Rate in Column 3. 12.3.2 Calculate the Iodine Dose Factor for each field location m 2 in Column 4. (The most recent calculated Iodine Dose Fac-tor may be used for future Child Thyroid Dose Projections.)

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-l 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 l Whole Body Dose Rate Projections. Multiply the scale fac-tor which was used in the Whole Body Dose Rate Projection fr3 (Form 1904.01B, Line 2.1) for the specific field location by j the ratio in Column 6 and enter the result in Column 7 of is Form 1904.01E. 13.0 ATTACliMENTS AND FORMS 13.1 Form 1904.01A - Existing Conditions Summary l 13.2 Form 1904.01B - Data Conversion Work Sheet 13.3 Form 1904.01C - Gaseous Release Rate Work Sheet 13.4 Form 1904.01D - EAL/Of fsite Dose Projection Work Sheet 13.5 Form 1904.01E - Dose Factor Determination by Field Measurement 13.6 Attachment 1 - Diffusion Overlay (Atomspheric Stability Category A) 13.7 Attachment 2 - Diffusion Overlay (Atmospheric Stability Category B) 13.8 Attachment 3 - Diffusion Overlay (Atmospheric Stability Category C) 13.9 Attachment 4 - Diffusion Overlay (Atmospheric Stability Category D) ) 13.10 Attachment 5 - Diffusion Overlay (Atmospheric Stability Category E) n()

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 subsector G to the projected extent of the plume). 10.3.2 If it is necessary to calculate plume arrival time (in hours) for a specific location, divide the distance (in miles) from the plant to the location by the windspeed (in mph). 10.3.3 If it is necessary to calculate the projected integrated dose (mR) for a specific location, multiply the local dose-rate (mR/hr) by the estimated duration of the release (br). 11.0 NOTIFICATIONS 11.1 Provide radiological release information to appropriate groups per 1903.10, " Emergency Action Level Response". G 11.2 The Emergency Radiation Team may be dispatched to obtain field radio-logical data at the discretion of the Duty Emergency Coordinator / Recovery Manager. 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. New data should be taken as specified by the Duty Emergency Coordinator / Dose Assessment Supervisor. NOTE: The following 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 at field locations on the plume centerline. This section is 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 Moni-toring Supervisor should dispatch offsite radiological monitoring teams to sample the plume at appropriate locations (to be determined at the time of the incident).

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 /Offsite Monitoring Supervisor and proceed as directed. NOTE: Real-time determinations should be compared to projected levels for corresponding time periods. 12.3 Determination of Iodine Dose Factor by Field Measurement. 12.3.1 Record on Form 1904.02F, the Field Location in Column 1, the Iodine Concentration in Column 2 and Whole Body Dose Rate in Column 3. 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 com-parison of a projceted 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 1904.02E) 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 1904.02F. 12.4.3 The most recent calculated ratios may be used for future Whole Body Dose Rate Projections. Multiply the scale fac-tor which was used in the Whole Body Dose Rate Projection (Form 1904.02D, Line 6) for the specific field location by the ratio in Column 6 and enter the result in Column 7 of Form 1904.02F.
