I I l 1.0 PURPOSE l l l l The projected offsite dose rates at various distances from the plant l l SHALL be calculated during an emergency involving a release or a l l potential release to the environment. l l l l The offsite dose projections should be used by plant management and l l offsite officials as a basis for determining protective actions such l l as sheltering or evacuation when the Protective Action Guides (PAG's) l l are exceeded. l l . I f

l This Instruction SHALL describe the method to obtain the required l l information and to calculate the offsite dose projections at various l l distances from the plant, by two methods: l l l l a. computer method, and l l l l b. hand calculation method when the computers l l are unavailable. l l l l 2.0 APPLICABILITY l l l l This Instruction SHALL apply to the Radiation Protection Group and all l l Radiological Emergency Coordinators. l I I l 3.0 REQUIRED EQUIPMENT l l l

5.0 PROCEDURE -

5.1 When it has been determined that a release to the atmosphere has occurred or there is a potential for a release to the atmosphere, ,

the Emergency Director SHALL designate the Radiation Protection Group responsible for projecting offsite dose rates.

5.2 Determine the exact flow path and the release rate from the plant. .

5.3 Determine the concentration of activity being released from the plant by either of the following methods:

(1) Radiation Monitors: The release concentration may be determined by obtaining the count rate or dose rate from the affected radiation monitor on the release path (e.g. R-22, R-50, etc.).

(2) Manual Determination: The activity being released via the '

steam headers or the shield building vent may be determined .

manually, in accordance with procedure, F3-20, " Manual l Determination of Radioactive Release Concentrations".  ;

(3) Sample Analysis: Sample analysis on the release path may be used to determine the isotopes for noble gas, fodines, and ,

particulates being released.

5.4 -Obtain the meteorological data from the following locations (See Attachment D):

(a) Met Tower - (MIDAS System)

(b) Alternate meteorological sources.

5.5 Perform all offsite dose rate calculations in accordance with Attachment A, B or C.

5.6 Report all results to the Emergency Director on a periodic basis.

Inform the Emersency Director immediately of any significant projected offsite dose rates.

5.7 Continue to calculate the projected offsite dose rates at approx-Laately 15 minute intervals, as per this instruction, until the emergency situation is terminated or until such time as determined  ;

by the Emergency Director or his designee.

5.8 The Radiological Emergency Coordinator SHALL notify the offsite officials of all projected offsite dose rates on a periodic basis or when requested.

The computer will also compute and display plume centerline doses (mR) to the thyroid when iodine is released, and a lung dose (mR) and whole body dose (mR) due ..)

, to inhalation of particulates when particulates are being released.

D - is the acceptgble value of relative deposition rate (meters )'as a function of distance from the source. The relative deposition rate is the deposition rate per unit downwind distance (Ci/sec per meter) divided by the source strength (Ci/sec), and represents a plume depletion factor due to dry deposition of elemental radiciodines and other particulates. This factor is obtained from Figure 5.

l F - is the acceptable value of the fraction of the release transported into the sector in question as located by the value for R and determined according to the distribution of wind direction.

This factor is obtained from Figure 6. -

l-Q - is the total radioiodine (elemental and non- -

elemental) or particulates released per event in units of microcuries.

R - is the distance in kilometers downwind from the release point where the deposition value is to be determined. .

28.26 - is a factor which (1) accounts for only elemental -)

radioiodine, (2) converts 22.5 degrees to radians, (3) allows R to be entgred in equatiog (a).as km, and (4) converts pCi/m to dps/100 cm .
