EdERGENCY PLAN 8MPLEMENTING PROCEDURE EP8P 303a Page 1 of 29 Revision 4 MANUAL DOSE PROJECTIONS Date 6/6/83 1.0 PURPOSE This procedure describes the use of the manual dose assessment method for estimating the downwind dose rates resulting from radioactive releases following an emergency at DAEC.

This procedure may also be used in conjunction with P. A.S. A.P. 7.4, " Estimation of Potential Release Rate," to evaluate the impact of potential releases to the general public.

NOTE USE OF THE IDP COMPUTER PROGRAM IS DESCRIBED IN EPIP 3.3b, " COMPUTERIZED DOSE PROJECTIONS".

2.0 APPLICABILITY The method described in the procedure is basically a manual backup to the IDP computer program, which is the primary means of dose projection during an energency at DAEC.

This procedure will be used by members of the Operations staff in the early phases of an emergency or by otner emergency response personnel whenever the IDP Computer program is not available.

3.0 RESPONSIBILITIES 3.1 Operations Shift Supervisor 3.1.1 Perform dose projection calculations until the Site Radiation Protection coordinator arrives, or the EOF is manned.

Initially advise local and State authorities of the results of 3.1.2 dose projection calculations and provide protective action recommendations as required, until the EOF is manned.

3.2 Site Radiation Protection Coordinator Perform dose projection calculations until the EOF is manned.

3.2.1 3.2.2 Initially evaluate the results of dose projection cale,ulations.

. 2.3 Initially identify the need for field survey data to backup projected dose calculations.

3.3 Emeroency Coordinator Initially advise local and State authorities of the results of 3.3.1 dose projection calculations and provide protective action recommendations as required.

3.4 Radiological Assessment Coordinator 3.4.1 Perform dose projection calculations Provide protective action recommendations as required.

3.4.2

EMERGENCY PLAN IMPLEMENTING PROCEDURE EPIP 3.3a Page 2 of 29 Revision 4 MANUAL DOSE PROJECTIONS Date 6/6/83 4.0 INSTRUCTIONS 4.1 General Instructions 4.1.1 The manual method involves the use of four dose projection l

charts (see Attachments 2-5).

The user must determine which of these four charts to use by determining the temperature l

differential (Delta T)'from the meteorological tower readout.

l At the same time, he will find the wind speed and direction.

To use the charts, he must calculate release rate by multiplying the appropriate monitor reading, by the system flow rate, a monitor correction f actor, and.000472.

In cross-referencing the release rate with the wind speed on the chart, the user will i

find a box that describes dose rates at five locations downwind for an elevated release and a ground level releare.

He will use the appropriate set of numbers and calculate the integrated dose at the desired location (s) by multiplying the dose rate from the l

chart, by the estimated duration of release. He will calculate elevated and ground level re' s separately, but will add the i

results to obtain a single c;a. rate for that location. This I

value should be compared with the EPA's Protective Action Guidelines, and will be the basis for protective action l

recommendations until the IDP computer program is available.

)

i 4.2 Soecific Instructions 4.2.1 Initial Dose Projection l

l l

a)

Using plant meteorological and effluent monitor readouts, fill in the boxes of Attachment 1.

Meteorological information can be obtained in the Control Room and release rate information can be obtained from the KAMAN System in the Control Room. Attachment 8 may be used by Control Room personnel to record this information for transfer to the Radiation Protection Coordinator, once the TSC is i

activ ated.

If intermediate or high range monitors are used, these numbers must be corrected according to the graph in Attachment 6.

Elevated and ground level releases must be calculated separately.

greater than 1.11 FG 5

NOTE IF METEOROLOGICAL DATA IS NOT AVAILABLE FROM THE PLANT, IT MAY BE OBTAINED FROM THE FLIGHT SERVICE STATION IN CEDAR RAPIDS AND/0R THE NATIONAL WEATHER SERVICE IN DES MOINES (PHONE NUMBERS ARE LOCATED IN THE EMERGENCY TELEPHONE BOOK). THE FOLLOWING CHART MAY BE USED AS AN ALTERNATE METHOD IN DETERMINING WHICH ATTACHMENT TO USE:

You will match the value of Rg (ground level release rate) and Re (elevated release rate) on Attachment 1 with the vertical axis of the chart (see Attachments 2-5).

You will match the value in box W with the horizontal axis of the ch art.

If you cannot find a release rate that is close to the values listed in the vert cal axis, then take the next most conservative value or multiples of existing chart values. For example, 80 Ci/Sec can be assumed to be an 100 Ci/sec release or you may use 4 times the value for 20 Ci/sec.

d)

The resultant intersecting rectangle from Step c) contains downwind doses at five specified downwind distances. The key on the chart describes the appropriate distances.

Each rectangle is divided into two sets of values. The values on the left are for an elevated release and the values on the right are for a ground level release.

Thyroid doses are 4 times the whole body dose rates given for elevated releases with the Standby Gas Treatment System (SGTS) in operation.

It is 400 times the whole body dose rate given for elevated releases without SGTS and for ground level releases. Thyroid dose rates described here are for children, and will provide the basis for protective action recanmendations.

NOTE THIS THYROID FACTOR HAS BEEN INTERPRETED FROM FIGURE 4.3 ON PAGE D.54 0F THE EPA PROTECTIVE ACTION GUIDELINES MANUAL.

f)

The user should next calculate the integrated dose for all three of'the following distances: 0 to 2 miles, 2 to 5 miles, and 5 to 10 miles downwind.

The values given by the charts are dose rates (mr/hr). To determine integrated dose, the user must estimate the duration of release in hours. Multiply this value by the dose rate for the location desired. For example, a 15 mr/hr dose rate will result in a total dose of 30 mr if the release was assumed to last 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br />.

NOTE IF NO ESTIMATE OF THE DURATION OF THE RELEASE IS READILY AVAILABLE, USE 12 HOURS.

g)

Refer to Attachment 1 to determine the significance of the integrated doses in regards to recommending protective actions for the downwind population.

h) d'escribes a detailed example of the manual method described in Steps a) through g) above.

4.2.2 Manual Backup Dose Projection If greater detail is desired in the dose calculation, the user may ignore the Dose Projection charts and use the following calculation method:

a)

To obtain dose rate (mr/hr), divide the release rate R (Ci/sec) by the wind speed W (mph) and then multiply the result by the dose f actor DF for the appropriate Delta T, release elevation, and desired distance downwind.

R will be obtained from Attachment 1.

Make sure your release rate was calculated based on corrected concentration monitor readings if intermediate or high range monitors were used.

Example A 27 Ci/sec elevated release in 5 mph wind, with Delta T of -1.2 l

(DF=10.76), will cause a dose rate of 58 mr/hr at 2 miles downwind.

R mr

- x DF = Dose Rate -

W hr 27 Ci/sec x 10.76 = 58 mr/hr 5 mph b)

A back calculation can be performed to determine release rate, if a dose rate is known at one of the five given downwind locations:

(dose rate x W)/DF = R You may now use this release rate to determine the dose rates at the other 4 downwind locations.

Example A dose rate of 17 mr/hr at 5 miles downwind, that was caused by a ground level release in a 9 mph wind, with Delta T of -1.05 (DF=11.32), resulted from a release of 14 Ci/sec.

(dose rate x W)/DF = R (17 mr/hr x 5 moh) 11.32

= 14 Ci/sec

I 1.0 PURPOSE This procedure describes the use of the IDP and EOF dose projection programs

[

for calculating the downwind dose rates resulting form radioactive releases following an emergency at DAEC.

j-i NOTE U5E OF THE MANUAL DOSE PROJECTION METHOD IS DESCRIBED IN EPIP 3.3a, " MANUAL DOSE PROJECTIONS".

2.0 APPLICABILITY This procedure will be used by the Site Radiation Protection Coordinator, the Radiological Assessment Coordinator and by other emergency response personnel assigned to operate the IDP/ EOF programs.

3.0 RESPONSIBILITIES 3.1 Site Radiation Protection Coordinator 3.1.1 Perform dose projection calculations until the EOF is mannad.

3.1.2 Initially evaluate the results of dose projection calculations.

3.1.3 Initially identify the need for field survey data to backup projected dose calculations.

3.2 Emergency Coordinator 3.2.1 Initially advise local and State authorities of the results of dose projection calculations and provide protective action recommendations as required.

3.3 IELP Radiological Assessment Coordinator 3.3.1 Perform dose projection calculations.

3.3.2 Provide protective action recommendations as required.

Computerized Dose Projections Revision 3 Date 5/23/83 4.0 INSTRUCTIONS NOTE THE IDP AND EOF PROGRAMS ARE ESSENTIALLY THE SAME COMPUTER PROGRAM BUT THEY USE DIFFERENT EMORY STORAGE AREAS OF THE VAX COMPUTER. IDP AND EOF ARE THE COMPUTER USER AREA NAMES AND PASSWORDS FOR ACTIVATING THE SYSTEM. THE IDP (INITIAL DOSE PROJECTION) PROGRAM IS OPERATED BY SITE PERSONNEL AT DAEC AND THE EOF (EMERGENCY OPERATIONS FACILITY) PROGRAM IS OPERATED BY CORPORATE PERSONNEL AT THE EOF IN THE IOWA ELECTRIC TOWER.

THEIR SEPARATION PERMITS INDEPENDENT OPERATION TO MAINTAIN DATA ENTRY CONTROL.

4.1 Starting the Program 4.1.1 Turn on the VAX computer terminal by flipping the black toggle switch, on the back of the video display, to the up position.

The printer-terminal in the TSC or E0F may be turned on by flipping the white power switch, on the frame stand, to the on position.

4.1.2 Wait a few seconds and hit the RETURN key.

IDP users will skip the next step (4.1.3), as it is for EOF users only.

4.1.3 Pick up the telephone receiver of the telephone next to the terminal, pull the left-most cradel button up as far as it will go (it is white, where the other one is clear). Listen for a normal dial tone and then dial the VAX data line phone number, as listed in the Emergency Telephone Book. After one ring, a shrill sound can be heard. Upon hearing this sound, carefully press the white cradel button down to its normal position, BUT NOT ALL THE WAY DOWN! Place the receiver on the table.

If the EOF printer-terminal is used, there is no special cradel button but there is a voice / data switch. Dial the Vax data line phone number with the switch in the voice position. As soon as you hear the shrill sound, flip the voice / data switch to data position and place the phone back on the crade'.

4.4.3 Shut off the terminal by flipping the black toggle switch, on the back of the video display, to the down position. Printsr-f terminals will be shut off by flipping the white power button, on the frame leg, to the off position.

4.5 Accessing and Eliminating Sum Tables Each distinct set of input data causes a sum table list file to be produce.d and saved in computer sto' rage.

In the EOF Program, these files can be seen by selecting choice 4 from the master menu prompt.

The IDP Program, however, will not directly give you a listing of the sum table list file. You must get a directory from the operating system cursor.

EMERGENCY PLAN IMPLEMENTENG PROCEDURE EPTP 3.3b Page 7 of 16 l

Computerized Dose Projections Revision 3 Date 5/23/83 As an example, the seventh version looks like this:

SUMTABLE.LIS;7 The comouter will always use the latest version of the sum table (your last run of the program).

If you want to use a sum table other than the latest one, see Attachment 3.

Occasionally, too many sum tables will be created for the limited space available in your computer user area. This will result in an OPEN FATLURE error. When this occurs, obtain the assistance of a system expect to eliminate unwanted sum tables, and make room for new ones.

4.6 Program Verification I

In order to assure the user that the program is functioning properly,

' lists a sample input set of values and the corresponding output release rate.

If the user is uncertain that the program is functioning properly, he may input those values and see if the computer produces the same output.

NOTE IF VERIFICATION FAILS, USE EPIP 3.3A, " MANUAL DOSE PROJECTIONS", INSTEAD OF THE COMPUTER.

Accessing Sum Tables The purpose of the attachment is to briefly describe the manner j

in which the user may load and run a sum table other than the l

most current one.

1.

Hit CONTROL and C keys simultaneously.

2.

When the operating system cursor (S) appears, type DIR and hit RETURN.

3.

Find the SUMTABLE.LIS:# file on the directory which has the largest version number (#).

4 Find the SUMTABLE.LIS version that you desire to view.

5.

Rename the desired SUMTABLE.LIS file to a version number one larger than the largest one on your directory.

f For example, SUMTABLE.LIS;34 is the latest file and you wish to view SUMTABLE.LIS;22.

type:

RENAME SUMTABLE.LIS;22 TO SbHTABLE.LIS;35 i

hit RETURN.

6.

Hit RETURN again to obtain USERNAME prompt and reenter the IDP/ EOF program.

7.

When you see the Previous Case prompt, answer Y.

The program t

will use the file with the largest version number.

8.

After viewing the data, it is reconsnended that you return to the operating system cursor and rename the version back to its original version number.
