1. Go to TSC and talk with RPC, then 1a. Ask key questions which might include:

HP II Dose Calculator. (1) What is OSCAR's status and that of any other Field Monitoring Team personnel?

(2) Is there a release or is one imminent?

(3) What is the emergency classification?

(4) What is-the affected sector?

TAB B EP-PS-1 05-B Revision 11 Page 1 of 4 MAJOR TASK:

Assist (as needed) the HP II Dose Calculator to ensure forward calculations are performed. When required, perform specialized calculations.

SPECIFIC TASKS: HOW:

1. Assist (as needed) the HP II Dose la. Use the following as needed:

Calculator to ensure forward calculations are performed. When HELP required, perform specialized TSC Dose Assessment Flowcharts calculations. See TAB 14 HELP Meteorological Data Acquisition See TAB 9 HELP Vent Monitor Data Acquisition See TAB 10 HELP MIDAS Operation See TAB 11 NOTE:

Instructions for obtaining vent data from PICSY are contained In TAB 9. This Is the preferred method for obtaining vent data. If PICSY Is unavailable, consult TAB 10 for vent monitor data acquisition. Chemistry assistance Is recommended If vent data Is acquired from the SPING control terminals.

TAB B EP-PS-1 05-B Revision 1 Page 2 of 4 SPECIFIC TASKS: HOW:

NOTE:

If difficulties are encountered or PICSY/SPING data Is suspect, Inform the RPC and request assistance from the Chemistry Coordinator. Initiating PAVSS and replacing "SPING" channels are tasks which must be performed by qualified chemistry personnel.

lb. Use the default Noble Gas to Iodine ratio of 1,000 and the default Noble Gas to Particulate Ratio-of 10,000 until Chemistry vent data is available.

HELP TSC Dose Assessment Flowcharts See TAB 14 1c. Periodically evaluate PICSY vent release data:

(1) Review measured/calculated dose ratios.

(2) Determine if low confidence (white) PICSY data exists.

NOTE:

"White" data Is an Indication of unreliable data. If may be normal and acceptable due to low or no flow In the SPING Monitor. It may also indicate a release exceeding the range of the Instrument or an Indication of Instrumentation or computer Interface problems.

TAB B EP-PS-105-B Revision 11 Page 3 of 4 SPECIFIC TASKS: HOW:

1d. If PICSY vent totals are questionable:

(1) Consult with Engineering to determine if condition is normal (i.e., per design) and if vent totals are valid from the Engineering or Dose Assessment perspective.

(2) Request Engineering promptly pursue corrective actions, obtain Chemistry vent sample data, and/or evaluate need to switch vent monitoring to PAVSS.

(3) Use appropriate alternate data such as grab sample (vent, PAVSS, HP air samples) results in Forward Calculation.

- HELP TSC Dose Assessment Flowcharts See TAB 14 Page 4 (4) Ensue OSCAR Is taking air samples as appropriate and is keeping their exposure ALARA.

(5) Report conditions as a potential unmonitored or an unmonitored release as appropriate depending on measured to projected dose rate ratios.

(6) Initiate Back Calculations if field data is available.

2. Notify the Operations Shift Manager if 2a. Discuss projection time with the RPC.

doses are projected to exceed 1 rem TEDE or 5 rem Thyroid CDE.

NOTE:

This may differ from the default projection time being used In the dose projection mode.

TABB EP-PS-105-B Revision 11 Page 4 of 4 SPECIFIC TASKS: HOW:

2b. Consider the following:

(1) Prognosis of event (2) Time to cooldown to<200 deg.

(3) Duration & type of release (4) Weather forecasts (5) Protective measures already implemented (6) Release pathway - possible filtration and/or monitoring

TAB C EP-PS-1 05-C Revision 6 Page 1 of 2 MAJOR TASK:

Manage OSCAR and other Field Monitoring Teams.

SPECIFIC TASKS: HOW:

1. Use the Health Physics Radioman to direct OSCAR and other Field Monitoring Team(s).

2. Ensure exposure of Field Monitoring 2a. Manage field teams such that the time Team personnel is maintained spent in a plume is productive and ALARA. minimized.

2b. Have field tearns perform calculations or sample analysis in low background area.

2c. When field teams are not being used, ensure the team is in a low dose rate area.

- HELP Onsite Emergency Monitoring Locations See TAB 13 2d. Obtain RPC approval for OSCAR to use respiratory protection when iodine cartridge from an air sample is >1200 cpm or RMS readings are greater than 1,000 mrem/hr Thy CDE. Protective clothing, and stay times based on plume activity should be evaluated.

NOTE:

Review RWP #8001 instructions regarding OSCAR activities.

TABC EP-PS-1 05-C Revision 6 Page 2 of 2 SPECIFIC TASKS: HOW:

NOTE:

Field monitoring teams other than OSCAR are not qualified to use respiratory protection. Their exposure to airborne radionuclides needs to be controlled via other means. RWP

1. 8002 provides Instructions regarding activities of field teams other than OSCAR.

2e. Consider the use of KI tablets if thyroid exposure approach or exceed 10 rem.

(1) Contact RPC if KI is needed for OSCAR or other field team personnel.

TAB D EP-PS-105-D Revision 6 Page 1 of 1 MAJOR TASK:

Validate existing dose calculations.

SPECIFIC TASKS: HOW:

1. Verify correct computer inputs. 1a. Review release rates, accident types, reactor mode switch, reactor shut down time, time of release, and weather conditions.

2. Compare OSCAR dose rate measurements to calculated dose rates. As time is available, compare dose rate measurements from other field teams to calculated dose rates at their monitoring locations.

3. If there is significant difference try to 3a. Consider these actions:

resolve. (1) Have OSCAR (or other team) survey area to determine centerline.

(2) Compare SPING release rates against back calculated release rates.

(3) Consider meteorological changes. -

4. Report conclusions to RPC.

TAB F EP-PS-1 05-F Revision 3 Page 1 of 1 MAJOR TASK:
