INITIAL DOSE ASSESSMENT I

1.0 PURPOSE AND SCOPE l

The purpose of this procedure is to provide a means of rapidly determining the initial off-site dose rates for a potential or ac-tual major release of radioactive material" to the environment, when the Radioactive Release Information System (RRIS) is not available.

This procedure shall be used until effluent samples have been taken and analyzed; at which time subsequent dose assessments will be in accordance with Intermediate Phase and Subsequent Dose Assessment, EIP-ZZ-02211.

2.0 RESPONSIBILITY The Health Physics Coordinator is responsi-ble for performing the initial dose assess-ment in accordance with this procedure.

f

(

3.0 INITIATING CONDITION N.J This procedure shall be initiated when the RRIS is not available and, either of the following conditions exist:

3.1 An Emergency has been declared with the classification of ALERT or higher and a release of radioactive material has occurred or has the potential to occur.

r 3.2-As determined by the Health Physics Coordi-nator, or Emergency Co.ordinator.

4.0 PROCEDURE The Health Physics Coordinator shall perform the following steps utilizing Attachment 2, Dose Assessment Worksheet when any of the initiating conditions (3.0) occur:

Determine the Meteorological Dispersion Fac-tor

[

4.1.1 Fill in the information needed to complete Box 1A in Attachment 2 by obtaining the in-formation from the Control Room instrument'ation.

4.1.2 If the primary tower information is not available in the Control Room, utilize the secondary tower indications and complete Box 13.

4.1.3 If no meteorological data can be obtained from the Control Room, dispatch an individ-ual to the meteorological tower to relay the needed information.

First to the primary meteorological tower and then to the secon-dsry tower as an alternate, if needed.

~

NOTE If an individual is dispat-ched to either meteorologi-cal tower, ensure he has the te:lephone number to contact the Health Physics h'S Coordinator.

l

4.1.4 Using the DELTA-T (90m-10m) determine the PASQUILL STABILITY CLASS from Table 1.1.

If DELTA-T (90m-10m) is unavailable use DELTA-T (60m-10m).

4.1.5 If aither DELTA-T values are not available, determine the PASQUILL STABILITY CLASS with the WIND DEVIATION (Sigma Theta) from the Secondary Tower using Table 1.2.

The o

Average Wind Speed must be greater than 2.24 mph to use this method.

.4.1.6 Record the STABILITY CLASS in Block 1C.

DETERMINE THE RELEASE RATES Release rates can be determined for the Unit Vent, Radwaste Building Vent and Atmospheric Relief Valves following the appropriate steps below.

Dose Assessment for other release pathways should be in accordance with EIP-ZZ-02211.

4.2.1 From the P.adiation Monitoring Panel in the control Room obtain the monitor readings for the release pathway:

Unit Vent, Radwaste Building Vent, or Atmospheric Release Valves.

Record the readings in Block 2A.

NOTE If more than one release path exists, a separate at-tachment 2 has to be com-pleted for each path.

4.2.1.1 If the Radiation Monitoring Panel is inoper-ative or values cannot be obtained, go to (n1?

Step 4.5 for contingency calculations.

d

'4.2.2 Transfer the monitor reading for the release path from Block'2A'to column 4C.

4.2.3 Determine the effluent flow rate utilizing one of the steps below.

4.2.3.1 Determine the unit vent exhaust flow rate utilizing information from the Control Room instrumentation.

Check on or off for each f

exhaust fan tag ID listed on Table 2.1, Determination of Unit Vent Flow Rate.

Add all design rated flows for fans which are operating.

Record flow rate on 2B and 4D.

I 4.2.3.2 The Radwaste Building vent exhaust rate is i

prerecorded in 23.

If the release is frcm the Radwaste Building vent, transfer the value to 4D.

DETERMINE THE CORRECTION FACTORS AND RATIOS 4.3.1 Utilizing Table 3.1, determine the sensitiv-ity correction factor for the correct moni-tor and accident type.

Note the accident type in 3A and record the correct sensitiv-ity correction factor in 3B.

NOTE The sensitivity correction factor corrects the monitor t-readings, which is based on XE-133 calibration, for the various isotopic mixes caused by the different type accidents.

Select the acci-

CONTINGENCY CALCULATION

- This step provides a method for estimating release rates, utilising conservative acci.

dont assucptions, in the event that no data is available from the Radiation Monitoring System.

This step should only be used until other data is available, as it is unlikely that an actual accident condition would be similar to those postulated.

4.5.1 Utilizing Table 5.1, Contingency Release Rate Table, determine the Noble Gas Release Rate for the accident type.

4.5.2 Substitute this value' for the monitor read-ing on 2A and 4C, and note "Yes" in 2C.

4.5.3 In the event that the indicators for the ex-haust fan ID are inoperable, utilize the total for the correct " Normal Fan Lin,e Ups" from Table 2.1, for the Effluent Flow Rate in 2B.

c 4.6 PROTECTIVE ACTION RECOMMENDATIONS (f

Upon completing the calculations in Attach-ment 2, assist the Emergency Coordinator in making any necessary protective action recommendations, in accordance with EIP-ZZ-

.00212, Protective Action Recommendations.

4.6.1 To make a Protective Action Recommendation, the Emergency Coordinator will need the fol-lowing information:

4.6.1.1 Projected Whole Body Dose Rate from Attach-ment 2, 4G.

4.6.1.2 Projecte[1. Child Thyroid Dose Rate from At-tachment 2, 4I.

J-DETERMINATION OF METEOROLOGICAL DISPERSION FACTORS (X/O)

AND PLUME DIMENSIONS This attachment provides a method for determination of meteorological dispersion factors and plume dimensions using onsite meteorological data from the Primary or Secondary Meterological Towers.

1.0 DETERMINE PASQUILL STABILITY CLASS 1.1*

Obtain the meterological data (previous 15-minute average) from the Control Room Analog Strip Recorders.

Record the primary tower'in-formation in the appropriate location on Form 1A and secondary tower-information if available.

^

1.2 If meteorological data is not$ available in the Control Room, obtain the information as follows:

1.2.1 Dispatch an individual to the shed at the pri-mary meteorological tower to relay this data from the analog strip recorder charts.

1.2.2 If information is' not availabic at the primary meteorological tower, dispatch an individual to Q'p j, the back-up shelter in the communications Equip-ment Room in the EOF to relay this data from the V.'

analog strip recorder (WIND SPEED, WIND DIREC-t TION and WIND DEVIATION (Sigma Theta) are r

available from the Secondary Meteorological Tower).

1.3 Using the DELTA-T (90m-10m) determine.the PASQUILL STABILITY CLASS from TABLE 1.2.

If DELTA-T (90m-10m) is unavailable use DELTA-T (60m-10m.)

1.4*

If either DELTA-T values are not available, 1

determine the PASQUILL' STABILITY CLASS with the

?

WIND DEVIATION (Sigma Theta) from the Secondary Tower using TABLE.1.3 The Average Wind Speed j'

must be greater than 2.24 mph to use this b

method.

i -

NOTE WIND DEVIATION (Sigma Theta) is the standard L

deviation of horizontal wind direction q

fluctuation.

bj 1.5 Record the STABILITY CLASS on FORM 1A.

~l NOTE If a distance falls between two values, use the higher Xu/Q value.

2.2 Using the XE/Q values,' determine the METEOROLOGICAL DISPERSION FACTOR (S)-(X/Q) for each SELECTED DISTANCE by dividing.X_g by the WINDSPEED(E).

Q 2.3 Record X/Q on FORM 1A.

!~

3.0 DETERMINATION OF PLUME TRAVEL TIME AND PLUME WIDTH 3.1 Using the WIND SPEED (u), determine the PLUME TRAVEL TIME for each selected distance of interest from TABLE 1.5, and record on FORM 1A.

, NOTE If the wind speed or selected distance falls between two values,.use the lower plume travel time.

3.2 Using the STABILITY CLASS, determine the PLUME WIDTH for each selected distance of interest from TABLE 1.6 and record on FORM 1A.

NOTE The PLUME WIDTH is the perpendicular distance from the plume centerline to where the concentration is less than 10% of plume cen-pe%

terline ccacentration.

+,.}

V 3.3*

If the STABILITY CLASS is D, E, F or G and the wind speed is less than 13 mph, using the STABILITY CLASS and WIND SPEED, determine the PLUME WIDTH CORRECTION DISTANCE from TABLE 1.7 and add the PLUME WIDTH CORRECTION DISTANCE to the PLUME WIDTH.

Record on FORM 1A.

NOTE The PLUME WIDTH CORRECTION DISTANCE is added to the PLUME WIDTH to conservatively account for the combined effects of increased plume meander and building wake on diffusion in the horizontal crosswind direction under light d

wind end stable or neut.ral atmospheric j

conditions.

4.0 DETERMINATION OF AFFECTED SECTORS 4.1 Plot the Plume Centerline and PLUME WIDTH on the Status Board 10 mile EPZ map to determine affected sectors.

4.1.1 Draw the Plume Centerline by plotting the point '180 from where the wind direction is from on the 10 mile radius cir-cle, and draw a line from that point to the plant or center of radius.

' [;1 ESTIMATION OF DOSE RATES' BASED ON ISOTOPIC ANALYSIS OF ENVIRONMENTAL SAMPLES This attachment provides the methods for calculating Whole Body and Child Thyroid Dose Rates, utilizing the results of ISOTOPIC ANALYSIS of ENVIRONMENTAL SAMPLES taken by the field monitoring team (s).

It is probable that the Whole Body dose rate or the child Thyroid dose rate would be the limiting dose rate in the early stages of an accident.

As an accident progresses, dose

-rates to other body organs (skin, lung, bone, etc.) and age groups (infant, teen, adult) should.be calculated.

NOTE Samples collected by field moni-toring teams for use in accordance with this attachment have to be returned to the EOF Laboratory (or other designated facility with gamma spectrosco gamma analysis. py capability) for The time expended by Field Monitoring Teams in returning samples to the EOF should be taken intc consideration before instructing teams to col-g.

  • DOSE PROJECTION / ASSESSMENT FOR PARTICULATE ACTIVITY This section provides the methods for projecting offsite'sur-

. face contamination levels utilizing data from the appropriate particulate effluent monitor or from isotopic analysis of an effluent particulate sample.

The method for dose assessment for the inhalation and ingestion pathways is also included.

-t This-attachment is generally to be used to deter-

?

i mine the long term affect of; the accident on the environment.

It may not be necessary to utilize this attachment for initial dose assessments.

Fnvironmental samples should be collected in ac-cordance with the Radiological Envir6nmental Moni ~

a i

toring Program (identified in QS-22).

Collection locations for sampling may be modified as deter-i mined by field surveys and/or dose projections and calculations performed in accordance with this procedure.

(This also includes section 1 of this attachment.)

1.0 DETERMINATION OF PROJECTED OFFSITE CONTAMINATION LEVELS

r.

I NOTE CONTAMINATION DOSE RATE CONVERSION FACTORS for isotopes that are not listed may be found in USNRC Regu-latory Guide 1.109.

These values must be multiplied by 1.0E12 PCi/Ci to correct for units.

2.3 Sum the DOSE RATE FROM. CONTAMINATED SUFJACES for each isotope and record the values obtained on At-tachment 12.

3.0 DETERMINATION OF INHALATION DOSE ASSESSMENT 3.1 Perform INHALATION DOSE ASSESSMENT for adults and children, utilizing the results of isotopic analysis of particulate air samples collected by Field Monitoring Teams.

These assessments are performed and recorded on FORM 9C and 9D.

NOTI This assessment should be performed after ini-O tial WHOLE BODY AND CHILD THYROID DOSE PROJEC-h]

TIONS are complete as inhalation dose equiva-J 1ents are comparatively small.

However, the m

significance of inhalation dose assessment may be increased if there is a significant holdup ~

of activity prior to release.

Inhalation dose assessment should be completed for the whole 4

body, the lung and for any organ whose inhala-tion dose factor is more restrictive (greater) than that of the lung.

3.2 Determine and record the CONCENTRATION of each iso-tope in the sample on FORM 9C and 9D.

3.3 Multiply the concentration of each isotope by the IN-HALATION DOSE FACTOR to obtain the INHALATION DOSE RATE for the whole body, lung, and restrictive organ (if any).

NOTE INHALATION DOSE FACTORS for isotopes that are not listed may be found in USNRC Regulatory Guide 1.109, Table E-7 (adult) and Table E-9 (child).

These values must be mul-tiplied by 6.55 Ell (child) or 1.42 E12 (adult) to incor-porate breathing rates and activity conversion factors i

CONTINGENCY CALCULATIONS F

This attachment provides a method to project offsite whole body and child thyroid doses, utilizing conservative accident assumptions, in the event that no data is available from the Radiation Monitoring System.

As it is unlikely that actual accident conditions would be similar to those postulated, this attachment should only be used until other data is available.
