RADIOLOGICALS RY 9.1 Radiolo ical Summar A Source Term The radiological source term assumed for this scenario was selected to include appropriate quantities of noble gas and radioiodine resulting from the postulated accident scenario.

Protective action recommendations i.e., sheltering or evacuation for certain Emergency Response Planning Areas (ERPAs) will not be required based upon the anticipated declaration of a Site Area Emergency and plant conditions. As a result of accident release rates, the projected whole body and thyroid doses will not exceed EPA Protective Action Guides beyond the Site Boundary.

The assumed noble gas and radioiodine release quantities are shown in Figure 9.1 as a function of time. The scenario involves two release points which is from the Air Ejector and the "A" Atmospheric Relief Valve (ARV). This occurs as follows:

Pre-Steam Generator Tube Rupture Time Release Point Release Rate C'ec 0700- Air Ejector 1.77 E-3 (Noble Gas) 0915 2.24 E-8 (Radioiodine)

The noble gas-to-radioiodine ratio assumed is 7.89 E4:1 during this period of release.

Time Release Point Release Rate Ci sec 0755- 8.32 E-3 (Noble Gas) 0810 1.76 E-9 (Radioiodine)

The noble gas-to-radioiodine ratio assumed is 7.89 E4:1 during this period of release.

Steam Generator Tube Rupture Time 8 Release Rate Ci sec 0915- Air Ejector 5.24 E-1 (Noble Gas) 0935 2.55 E-4 (Radioiodine)

The noble gas-to-radioiodine ratio assumed is 2000:1 during this period of release. Isotopic breakdowns of assumed noble gas, radioiodine and particulate release quantities are provided in Table 9.1.

Time Release Point Release Rate Ci sec 0935- Air Ejector 6.23 E-2 (Noble Gas) 0955 3.12 E-5 (Radioiodine)

The noble gas-to-radioiodine ratio assumed is 2000:1 during this period of release. Isotopic breakdowns of assumed noble gas, radioiodine and particulate release quantities are provided in Table 9.1.

B. Inte rated Offsite Doses Due to Plume E osure The downwind integrated doses from the scenario release are as follows:

Time Release Point Inte rated Dose Rem 0700- Air Ejector 1.25 E-4 (Whole Body) 0915 8.75 E-7 (Child Thyroid) 0755- 6.S2 E-5 (Whole Body) 0810 7.63 E-9 (Child Thyroid)

METEOROLOGICAL ASSUMPTIONS

Meteorolo ica Conditions Basis The meteorological conditions for this scenario were based upon historical meteorological data recorded by the Ginna primary weather tower and the National Weather Service on Au ust 22 1988. Minor editting was performed on the data to provide the wind direction and atmospheric stability conditions required by the scenario during the period of release.

National Weather Service and other Exercise controllers will provide Exercise participants weather forecast summaries based on the meteorological data and other supporting information available from the historical record.

The goal of this approach is to provide participants with more realistic forecast information.

Scenario Assum tions The scenario begins with light, southerly winds which shift and become northeasterly by mid-morning.

During the period of release due to the Steam Generator Tube Rupture (0915-0955 hr), the average meteorological conditions are as follows:

Wind Speed 5 mph (at 33 ft)

Wind Direction 50 degrees (at 33 ft; wind from)

Pasquill Stability = E
