7.5 Dose Projections and Field Monitoring Team Survey Maps and Data

Edwin I. Hatch Nuclear Plant Emergency Preparedness 2003 Exercise 04 7.5 Dose Projections and Field Monitoring Team Survey Maps and Data The attached dose projection information provides the MIDAS dose assessment program outputs from each 15-minute projection period. It consists of a plume map which is a screen print of the Total Effective Dose Equivalent (TEDE) rate projection used for procedural radiological release determination and some Emergency Action Level (EAL) parameters. The second page is the MIDAS printout which is a 'copy' of the Emergency Notification Network (ENN) form containing the 4-hour dose projections used for EAL determination and Protective Action Recommendations (PARs).

The attached plume maps provide radiological data in the simulated effluent plume.

Maps are provided covering the time of the release in 15-minute intervals. The data provided approximates values that would be obtained by an elevated release model.

For realism, controllers will randomly vary the data among the range indicated by the contour legend.

Data provided by the controllers should average out to the value of the contour in question.

All field monitor readings for times prior to the start of the release will be "AS READ".

Data are provided in the following categories:

Field Monitor Gamma Dose rates (closed window)

Field Monitor Gamma plus Beta dose rates (open window)

Field Monitor Thyroid dose rates Ground contamination (I -131)

The following information is provided for use by controllers:
