1.1 Energize the RAC Computer.

1.2 Start a lo of activities performed.

1.3 Call out additional resources 1.3.1 For the duty roster RAC, determine from the Emergency Director (ED) if the duty roster has been called out. If not, get the RAC's phone number from the ED and call him/her.

1.3.2 For call-out of additional R.C. Techs, obtain phone numbers from the Rad Con Field Ops phone list and call the needed techs.

1.4 Determine release Pathway. Consult with the ED or his/her designee to determine the pathway of any radioactive releases from the plant.

NOTE Refer to the Emergency Dose Assessment User's Manual section of the EDCM located in the RAC locker for guidance in performing dose projections.

1.5 Obtain and validate the initial dose proiection within 15 minutes.

1.5.1 Select the RAC Spreadsheet icon from the desktop of the RAC Computer.

1.5.2 Go to the release pathway specified by the ED.

O Select the Update Plant Data option to import PPM and Met Data.

O If the pathway is being monitored by an RMS monitor, use the RMS option for that pathway.

) If the pathway is not being monitored by an RMS monitor, use the leak rate option for that pathway.

O Verify that the PPM and Met Data is current (15 minutes old or less). If not, all data will need to be input manually.

o Enter data not available from the PPM as specified by the input sheet.

o Edit any PPM or Met Data that is not believed to be accurate.

0 Print dose projection.

1.9.1 To activate field teams:

1.9'.1.1 Perform radio checks with the field team(s).

1.9.1.2 Assign and record field team designations (e.g. Alpha, Bravo, etc.)

1.9.1.3 Obtain and record names and SSN's for all field team members.

1.9.1.4 Obtain and record year-to-date TEDE for all field team members.

1.9.1.5 Inform team members of the current wind direction and speed and display it on the EPZ map.

1.9.2 Field monitoring team placement and direction: consider the following guidelines for placing and directing field team(s).

1.9.2.1 For ground level releases (highest doses projected at site boundary)

O Place the first field team downwind at the site boundary.

0 Place the second team (if dispatched) off-site, downwind and as near to the site as possible.

1.9.2.2 For elevated releases (highest doses projected at some distance from the site)

O Place the first field team downwind at the location where the highest dose is projected.

O Place the second team (if dispatched) downwind nearer to the site than the first team (results from this team aid in determining if the plume touched down closer than projected).

1.9.2.3 Instruct the team(s) to scan across the plume and attempt to locate plume centerline.

O Provide a definite start point, direction of travel and an end point for scanning (e.g. "scan for plume centerline starting at NNE31, travel toward the Southeast passing through NE31 and continue to ENE31").

Activation of the RAC 7 EXHIBIT 2 Page 3 of 6 1.11.4 Monitor field monitoring team doses. If field monitoring team thyroid doses are projected to be 25 REM '(CDE) or greater:

O Request permission from the Group Leader- Rad. & Env. Controls to authorize field monitoring teams to self-administer thyroid blocking agent.

NOTE Instructions for field monitoring team use of thyroid blocking agent are contained in procedure, EPIP-TMI-.10, Onsite/Offsite Radiological/Environmental Monitoring.

o Advise field monitoring teams to utilize respiratory protection to the extent practical without compromising their safety.

1.11.5 Once the EACC is operational, coordinate the placement of field monitoring teams with the EAC.

1.11.6 Transfer responsibility for off-site field monitoring team(s) to the EACC when they are ready to assume that responsibility.

1.12 Dose projection/field readings comparison: use the following guidance for comparing field readings (field team or Reuter Stokes readings) and dose projections.

1.12.1 If field readings are within a factor of 10 less than (and not more than) the corresponding projected value, a very good correlation exist between the two.

1.12.2 Field iodine sample results, after being converted to thyroid dose rate (CDE per hour), can be directly compared to MIDAS projected thyroid dose rate.

1.12.3 Field team closed window dose rates and Reuter Stokes readings can be compared with DDE values in dose projections.

1.12.4 There is no dose projection value that corresponds directly to field team open window readings. Open window readings that are higher than closed window readings indicate that the plume is at ground level at that location.

1.13 Samples: Consider the need for special samples (e.g. MAP-5, CATPASS, RCS-PAS)to provide more precise source term data for dose projections.

1.13.1 Samples taken directly from the effluent pathway (e.g. condenser off-gas, MAP-5, etc) provide the most precise source term data.

1.13.2 A sample from the Reactor Building atmosphere (i.e. CATPASS) will improve the precision of source term data for releases from the Reactor Building but will likely be less precise than effluent samples.

Number TMI - Unit 1 Emergency Procedure EPIP-TMI-.07 Title Revision No.

Activation of the RAC 7 EXHIBIT 2 Page 4 of 6 1.13.3 RCS sample results are useful in determining the extent of fuel damage and can be used to improve the precision of the source term but to less an extent than effluent samples.

NOTE The Emer. Dose Assessment User's Manual contained in the EDCM (Ref. 6.3) provides guidance on which sample(s) to obtain under various conditions.

1.14 Communication with BRP: Establish communication with the Bureau of Radiological Protection (BRP) and provide TMI dose projections to them.

1.15 Communication with NRC: If the NRC requests continuous communication on the HPN, establish and maintain communication on the HPN with them and:

1.15.1 Assign an extra RAC staff member as soon as one is available or, 1.15.2 Request an additional communicator from the ED Assistant.

1.16 Coordinate all Radiological Controls activities on-site, including:

o Access control to areas affected by the emergency.

0 Personnel dose monitoring and control (including dose extensions).

0 In-plant surveys and samples.

1.17 Thyroid Blocking: Implement the Thyroid Blocking procedure (EPIP-COM-.44) if it is anticipated that person(s) will be exposed to quantities of radioiodine sufficient to cause a thyroid dose of 25 REM (CDE) or greater.

O Field Monitoring Teams: If field monitoring team thyroid doses are projected to be 25 REM (CDE) or greater, authorize team members to self-administer thyroid blocking agent.

Instructions for field monitoring team use of thyroid blocking agent are contained in procedure: EPIP-TMI-.10, Onsite/Offsite Radiological/ Environmental Monitoring.
