1. PURPOSE AND SCOPE 1.1 The purpose of this procedure is to estimate off-site  !

whole body exposure rates from Xenon-133, and thyroid i exposure rates to adults and children from I-131 for accidental, uncontrolled releases.

1.2 Radioactive particulate material is not addressed because protective actions are based on assuming the iodine 4

exposure pathway is critical, and should provide suf-ficient protection from radioactive particulate material.

(Based on information from Section 5.1.2 of EPA-520/1-75-001, Revised 6/79.)

3. RESPONSIBILITIES

( i l

I In the event of the accidental release of gaseous radioactivity, l

1 _ _ - -- --

2 AD 1827.10.11 the Shift Supervisor shall make an initial evaluation of the situa-tion and classify the emergency in accordance with EP 1202.37, High Airborne Activity.

3.1 For local releases, any calculation of release rates and 11 dose rates should be done under the direction of the Shift Supervisor by:

1. An Administrative Assistant, or

2. Other qualified, available personnel.*

• The STA may perform release and dose rate calcula-tions if the STA feels that performing such calcula-tions does not' interfere with his primary respon-sibilities of maintaining a broad perspective of the event and consulting with the Shift Supervisor.

Requirements for notification of other persons to deal with these types of releases are found in the EI 1300 series, Emergency Plan Implementing Procedures, and EP 1202.37, High Airborne Activity, and AD 1839.00, Station Operations.

3.2 For conditions that require Emergency Plan implementation, release rates and dose rates should be performed under the direction of the Emergency Duty Officer (EDO). The Shift Supervisor, acting as interim EDO, should designate:

1. An Administrative Assistant, or

2. Other qualified, available personnel,*

11 to perform these calculations. If the Emergency Control Center has been activated, the designated EDO should direct response personnel within the ECC to perform the dose calculations relieving the Shift Supervisor of this responsibility.

• The STA may perform release and dose rate calculations if the STA feels that performing such calculations does not interfere with his primary responsibilities of maintaining a broad perspective of the event and consulting with the Shift Supervisor.

4. PROCEDURE CAlTfION: This procedure only addresses releases from the 11 Station Vent. For release from the MSSV's, Auxiliary Fced Pump Turbine Exhaust, and Atmospheric Vent Valves, see EP 1202.57.

l 3 AD 1827.10.11

'~'N 4.1 Complete Data Sheets No. I and No. 2. Instructions for completing the required information are provided on the Data Sheets.

NOTE: If data cannot be obtained from the site meteoro-logical tower, backup data to perform Offsite Dore Calculations may be obtained by calling the agencies listed in Attachment 2,Section IX.6 of Admin. Memo No. 37.

NOTE: A programmable calculator and its printer (located 11 in the Shift Supervisor's Office and Emergency -

Control Center) may be used in place of Data Sheets No. I and 2. See Attachment 1 for instruc-tions.

11 4.2 Use AD 1827.12 Protective Action Guidelines to determine '

the protective actions to be initiated. The EDO should make plume exposure recommendations per this procedure.

4.3 If an evacuation is initiated, it should include an area 22 1/2' to 45' each side of the plume center line (Based on Appendix I from NUREG-0654/ FEMA-REP-1).

4.4 If evaluations or RMT sample results indicate ingestion exposure that exceeds the plume exposure evacuation area, recommendations for further evacuation should be made by

~~-11 the Emergency Operations Manager in accordance with ingestion exposure Protective Action Guidelines given in AD 1827.12.

4.5 Should the NRC request direct contact with the it.dividual performing offsite dose calculations, it is the respon-sibility of the Emergency Duty Officer to ensure that the requesting NRC official is contacted directly by an appropriate cognizant individual. Any available phone could be used for this purpose.

I 15 AD 1827.10.11 0FFSITE DOSE CALCULATIONS USING TI PROGRAMMABLE CALCULATOR A miniprogram for the TI programmable calculator and its printer has been developed to simplify the offsite dose calculations. The program is divided into six sections which are discussed below. Samples of runs of each section are attached; circled items are inputs. Each section performs a different type of calculation, and each can be performed independently with the exception that either the noble gas or iodine release rate calculation must be performed once before any other section is run.

The program is not permanently stored and must be loaded into the cal-culator prior to use.

11 NOTE: The program does not include Table 3 Xp/Q values for stability class G, thus for those instances where a stability class G exists, hand calculations should be performed, however, if time constraints require using the calculator, stability class F should be used.

(The values obtained using F stability class will be approximately 50% low.)

LOADING PROGRAM:

The program is encoded on both sides of two magnetic cards kept with the calculator. Ilandle__these_ cards only_by,the edges. The sides are marked 1-4. To load the program, perform the following steps in order:

C 11 1) Turn on the printer, and then the calculator (printer switch on right side), then press; 1, 2nd, OP, 17 on the calculator, the calculator should display 879.09.

2) Press "1" and "+/ "

3) Feed the end of the magnetic card labeled "1" into the program slot on calculator side - the calculator will automatically feed the

card through the calculator and out the other side pull the card out by the edges.

11 NOTE: If the calculator read the card properly, the (-1) will be shown in the display; if the (-1) is flashing, the card was read improperly. If this occurs, press clear and reenter the card.

4) Press "2" and "+/ "

5) Repeat the feeding process with side 2 of first card

6) Press "3" and "+/ "

7) Repeat the feeding process with side 3 of second card Attachment 1 Page 1 of 9

1 g AD 1827.10.11 g) Press "4" and "+/~"

9) Repeat the feeding process with side 4 of second card

10) Proceed by pressing A for noble gas or B' for iodine release rate calculations, either program will print a line of output on the printer which finalizes the program within the calculator.

11 11) Finally, run programs E (see page 5 of 9) and 2nd A'(see page 6 of

9) tp test that each of the main programs will run with fixed data.

These test routines ensure that the program was loaded in the cor-rect sequence into the calculator memory. Compare your printout with the output listed below each of the programs (E and 2nd A').

If an error (an incorrect output line or a flashing display) was encountered during either of the test runs, the user can reload the program (following the above procedure) or if the error continues contact the calculator programmer (Technical Section) for assistance.

11 PROCEDURE:

Once the program has been loaded as stated above, start any of the calculations by pressing the A, B, C, or D buttons (top row of calculator) corresponding to the functions described below:

11 NOTE: To enter data, simply input the values in standard or scientific format, then press "R/S". (If an error is made in the entry, press "CE" and reenter the value.) Also note that the calculator may be used in the normal manual mode without affecting the programming; when manual calculations are complete, to re-initiate a program simply l press the button (s) corresponding to the desired calcula-tion.

A - NOBLE GAS REIIASE RATE This program calculates the noble gas release rates in curies /sec from the stack. As input, it requires the countrate from the noble gas monitors (RE2024C, 2025C) and the stack flow rate in KCFM.
