~... ~ DRAFT o L Radiation Dose Assessment The data tables, worksheets, and curves on the following pages unay be used to classify the magnitude of accidental airborne s releases and assess the offsite consequences. The red, yellow, and white emergency designations are based on dose ranges in Table 5.2 of the " Manual of Protective Action Guides and Pro-tactive Actions for Nuclear Incidents", Environmental Protection Agency, Office of Radiation Programs, Environmental Analysis i Division, EPA-520/1-75-001, September, 1975. Their definition is Red Emergency Whole Body 5 rem and above Thyroid 25 rem and above Yellow Emergency Whole B3dy 1 to <5 rem Thyroid 5 to <25 rem White Emergency Whole Body .05 to <1 rem Thyroid .3 to <5 rem

()

The following steps may be used to assess the offsite consequences: 1. For each monitor reading (drywell or SGTS), the projected activity released (Xe-133 or I-131 effective activity) for any 8 hour period to 192 hours may be found using the Tables and Worksheets on pages 4 through 15. 2. The worst radiological emergency condition is determined using the worksheet on page 16 and the curves on pages 17 and 18 along with the releases determined in item 1 (or by other means) and with the current wind speed. 3. The emergency condition may then be defined at the exclu-sion area boundary or any integral number of miles from the release point to 10 miles using the releases de; ermined in item 1 (or by other means), the current meteorological data, and the worksheet, tables, and curves on pages 19 through 23. (:) Page 1

f O j 4. The projected dose at any point in item 3 may be determined j using the releases determined in item 1 (or by other means), the current meteorological data, and the worksheet and tables on pages 24 through 26. The curves on pages 27 and 28 provide the dose ti:nes wind speed per curie released at any point between the EAB and 10 miles. 5. The downwind boundaries of the affected area may be defined according to radiological emergency condition (Red, Yellow, and White) uaing the releases deterrained in item 1 (or by other means), the current meteorological data, and the worksheets and curves on pages 29 through 32. 6. The projected downwind dose at various distances within the affected area may be determined using the releases deter-I mined in item 1 (or by other means), the current meteorolo-gical data, the worksheets on pages 33 and 34, and the curves on pages 31 and 32. l I 1 s e a e O Page 2 0

O 2 Evaluation of WUREG-0654 General and Site Bnergencies Ths' data tables on the following pages may be used to determine if IECREG-0654 General and Site Emergencies exist. i, The data in the table on page 35 present the drywell and SGTS I monitor readings'as calculated for a release of 100% noble gases to the drywell at^0. hours after shutdown. A similar 2 table on page 36 is for a release of 1004 noble gases and 25% iodines at O. hours after shutdown. The ratio of the actual monitor reading to the value in the table is a measure of the actual fraction of the' stipulated release. The data in the tables on page 37 present the minimum fraction / wind 'r speed that would result in the indicated emergency. Also, the allowea, wind speed range is given. T The data in the tables on pages 38 through 43 give the monitor reading that would result in a projected emergency condition. 2 s For monitor reading's greater than or equal to those in these s tables, an emergency condition exists.
