EDA-3 0FF-SITE DOSE PROJECTIONS FOR MCGUIRE NUCLEAR STATION

1.0 PURPOSE

1.1 To describe a method for projecting dose commitment from a noble gas and/or iodine release, through the containment, the unit vent and/or the steam relief valven, during an emergency. Where appropriate, the Dose Assessment Coordinator, or designee, may deviate from this procedure due to varying plant conditions.

, 1 2.13 McGuire Nuclear Station Class A Computer Model Validation.

3.0 LIMITS AND PRECAUTIONS:

3.1 This procedure is an alternative method of dose at.sessment to the Class A Atmospheric Dispersion Model computer code.

3.2 This procedure applies to releases made from McGuire Nuclear Station only. Many of the values contained in this procedure are site specific.

3.3 It is assumed that the whole body dose from an fodine release is very small compared to the thyroid dose; therefore, lodine whole body dose is not considered here.

3.4 This procedure considers all releases to be ground level releases and that all meteorological data are 15 minute averages.

3.5 Once a zone has been added to the list of affected zones, it shall not be removed except under the direction of the Dose Assessment Coordinator.

3.6 Once the Crisis Management Center (CMC) has been activated, the doses calculated by the Technical Support Center (TSC) dose assessment group, shall be compared with those calculated by the CMC before an evacuation recommendation is made.

3.7 EMF's 38, 39, and 40 willisolate on a phase A containment isolation (1 psig in containment) . Therefore, EMF's 38L, 38H, 39L, 39H , 40 and 48 should not be considered valid when containment pressure is > 1 psig.

3.8 The sample pump to EMF's 35, 36, and 37 will trip when there is a Trin 1 on EMF 36 HH. Therefore, EMF's 35L, 35H, 36L, 36H, and 37 should not be considered valid when EMF 36 HH is > Trip 1 (usually set at 5-7 R/Hr).

4.0 PROCEDURE

NOTE: Much of the information for the meteorology assessment can be obtained on the OAC, (Tech. Spec. 04 program) . See Enclosure 5.14 for instructions.

4.1 Meteorology Assessment 4.1.1 Acquire the following information and record on the Dose Assessment Report and Meteorology Worksheet (Enclosures 5.1 and 5.2 respectively).

4.1.1.2.2 If the wind speed or wind direction can not be obtained from plant systems, obtain them from the National Weather Service (phone 359-8284). If the NWS information is unavailable, then obtain data from the CNS Control Room (8-831-2338).

4.1.1.3 Temperature gradient (AT) in degrees contigrade.

4.1.1.4 Using Enclosure 5.3, determine the stability class based on AT. If AT is unknown, then the following applies:

1000 hours0.0116 days <br />0.278 hours <br />0.00165 weeks <br />3.805e-4 months <br />, use stability class G.

4.1.1.5 If necessary, use forecasted meteorological data for calculating doses due to changing meteorological conditions.

4.1.2 Determine the atmospheric dispersion parameters , XTQ (sec/m3 ), for .5, 2, 5 and 10 miles (record on Enclosure 5.1).

4.1.2.1 Using AT, deterndne the two hour relative concentration value (C,i) from Enclosure 5.3.
