This checklist need not be completed by the On-Shift RAC prior to turnover per Step 1.11. NOTE The bold underlined steps below are particularly important in the early stages of an emergency.

They should be performed promptly and in an orderly manner. 1.1 Energize the RAC Computer.

1.2 Start a loc of activities performed.

1.3 Call out additional resources if they are needed. If no additional resources are needed at this time, skip the step but reconsider it later as needs change. 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 (or have someone obtain) phone numbers from the Rad Con Field Ops phone list and call (or have someone 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.

5 TMI -Unit 1 Number Emergency Procedure EPIP-TMI-.07 Title Revision No. Activation of the RAC 9 EXHIBIT I Page 2 of 5 1.5 Obtain and validate the initial dose projection 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. 1.5.2.1 Select the Update Plant Data option to import PPM and Met Data. 1.5.2.2 If the pathway is being monitored by an RMS monitor, use the RMS option for that pathway.

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

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

1.5.2.5 Enter data not available from the PPM as specified by the input sheet. 1.5.2.6 Edit any PPM or Met Data that is not believed to be accurate.

1.5.2.7 Print dose projection.

1.5.3 Validate the dose projection by performing the following checks:

• Verify that the correct release pathway is being used.

• Verify that the monitor input data is accurate and appropriate (e.g. no calibrations in progress).

• Verify the release duration with the ED.

• Verify that the dose projection results are consistent with other indications.

1.5.4 Use the Total Dose Option to verify no other pathways are contributing to the offsite dose. 1.5.5 If power is lost to the RAC computer, request assistance from Operations in obtaining power. An extension cord is available in the RAC locker. 1.6 Review the dose projection with the ED. Ensure the ED understands the nature of the dose projection (e.g. bounding calculation, contingency projection, "what-if", etc.) and the precision or uncertainty associated with the dose projection..

1.7 Review the Emergency Classification with the ED as it relates to current radiological parameters and evaluate the need to escalate to a higher classification.

6 Number TMI -Unit 1 Ememencv Procedure EPIP-TMI-.07 Title Revision No. Activation of the RAC 19 EXHIBIT 1 Page 3 of 5 1.8 Advise the ED on any of the following issues if they apply. Skip any that do not apply but reconsider them as the emergency conditions change.

• Protective Action Recommendations (PAR) (see the PAR logic diagram in procedure EPIP-TMI-.02, Emergency Direction, available from the ED).

• On-site assembly and site evacuation of non-essential personnel (see the table at the end of this exhibit for guidance).

NOTE The automated Emergency Report Form that is produced by ED automatically suggests assembly location and evacuation routes contained on the table in this exhibit.

• Contaminated and/or injured employees and any decontamination efforts.

1.9 Consider dispatchingq a field monitorinq team if the dose projection indicates the potential for abnormal radiological conditions off-site.

1.9.1 To activate field teams: a Perform radio checks with the field team(s).

0 Assign and record field team designations (e.g. Alpha, Bravo, etc.) 0 Obtain and record names and SSN's for all field team members.

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

& 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).

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

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

• Place the second team (if dispatched) off-site, downwind and as near to the site as possible.7 TMI -Unit 1 Number Emergency Procedure EPIP-TMI-.07 Title Revision No. Activation of the RAC 9 EXHIBIT 1 Page 4 of 5 B. For elevated releases (highest doses projected at some distance from the site)

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

• 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).

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

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").

1.10 BRP call back: Within 45 minutes of event declaration notify the ECC Communications Coordinator whether the BRP has called back to the RAC. 1.11 Provide a turnover to the IREO RAC upon arrival.8 EXHIBIT I On-Shift RAC Checklist EPIP-TMI-.07 Revision 9 Page 5 of 5 Guidelines for Selection of On-Site Emergency Assembly Area and Evacuation Route for Non-Essential Personnel Off-Site Remote On-Site Emergency Gate To Be Assembly Area To Wind Direction Assembly Area To Route to Emergency Used For Site Be Used For Site (from) Use Assembly Area Evacuation Evacuation 10 to 800 Warehouse I Personnel in the NOB, OSF, North Gate Training Center Protected Area and other locations near Unit 1 use most direct route to Warehouse

Radiological conditions:

In-plant (including habitability concerns in emergency facilities), On-site and Off-site 10 NOTE The following steps should be considered and, if needed, implemented.

These steps need not be performed in the sequence listed and may be performed multiple times. The RAC should periodically review this checklist to ensure that necessary steps are being performed.

I TMI -Unit 1 Emergencv Procedure Number EPIP-TMI-.07 Title Revision No. Activation of the RAC 9 EXHIBIT 2 Page 2 of 5* Employee doses and emergency dose extensions.

• Contaminated employees, decontamination efforts and any use of Thyroid Blocking agent. F. Emergency classifications:

Recommend emergency classifications to the ED based on radiological conditions and Emergency Action Levels (EAL). G. Fuel damage assessment:

Provide any necessary assistance to the TSC for the assessment of fuel damage and report results to the ED.NOTE While the RAC should provide assistance to the TSC in assessing the degree of core damage, the 'official' damage assessment values will be determined by the TSC.H. Primary to secondary leak rate determination:

If a primary to secondary leak exists, use the Emer. Dose Assessment User's Manual contained in the EDCM (Ref. 6.3) to assist in determining primary to secondary leak rate. Coordinate with the TSC in making this determination.

NOTE While the RAC should provide assistance to the TSC in estimating the primary to secondary leak rate, the 'official' leak rate values will be determined by the TSC. When the EACC is staffed turn over field monitoring teams to the EACC.J. Dose projection/field readings comparison:

use the following guidance for comparing field readings (field team or Reuter Stokes readings) and dose projections.

• 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.

• Field iodine sample results, after being converted to thyroid dose rate (CDE per hour), can be directly compared to projected thyroid dose rate.11 NOTE Consideration should be given to locations on-site where personnel may remain. Examples are: -Security Posts -Warehouses

-Communications

-Medical I.I I Number TMI -Unit 1 Emerency Procedure EPIP-TMI-.07 Title Revision No. Activation of the RAC 9 EXHIBIT 2 Page 3 of 5

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

• 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.

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

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

• 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.

• 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 Users Manual contained in the EDCM (Ref. 6.3) provides guidance on which sample(s) to obtain under various conditions.

L. Communication with BRP: Establish communication with the Bureau of Radiological Protection (BRP) and provide TMI dose projections to them. M. Communication with NRC: If the NRC requests continuous communication on the Health Physics Network (HPN), establish and maintain communication on the HPN with them and:

• Assign an extra RAC staff member as soon as one is available or,

• Request an additional communicator from the ED Assistant.

N. Coordinate all Radiological Controls activities on-site, including:

• Access control to areas affected by the emergency.

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

• In-plant surveys and samples.12 Number TMI -Unit I Emergencv Procedure EPIP-TMI-.07 Title Revision No. Activation of the RAC 9 EXHIBIT 2 Page 4 of 5 0. 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.

P. Interface with the Group Leader- Radiological and Environmental Controls (GL-R&EC) regarding:

• Dose projections

• In-plant and on-site conditions

• Protective actions Q. Recommend source term reduction techniques appropriate to the release pathway (e.g. RB spray, raising OTSG levels, etc). See the Emergency Dose Assessment User's Manual in Ref 6.3 for specific information.

R. Evaluate the need for eating and drinking restrictions in-plant.

• If results of habitability monitoring allow, recommend that the E.D. lift restrictions, as needed.

• Ensure habitability monitoring continues.

S. Review radiological information in press releases.

Specific examples of radiological information that should not be included in press releases are: 0 Dose projections

• Protective action recommendations

• Technical terms

• Acronyms and abbreviations T. Trend effluent release data, RMS, sample results, field team readings and dose projections.

These sections can be repeated as needed. A. Plume centerline scans: 1. General Guidance:

• Scanning is most effective when the team slowly travels across the plume at approximately a 900 angle to the wind direction.

• Scanning should be performed with a frisker or a survey instrument.

If a survey instrument is used, the probe window should be open.

• In inclement weather, the instrument probe should be covered with a surgeon's glove or plastic bag to keep it dry. 2. Ask the RAC/EACC to specify a start and stop point for scanning.

If the RAC/EACC provides no direction, consult the map and choose a route which runs as nearly perpendicular as possible to the expected plume direction.

3. Proceed to the start point with the survey instrument/frisker turned on. 4. Scan by driving slowly (- 15 m.p.h.) while holding the instrument probe outside the vehicle.

5. Locate the point where the instrument reading is highest.

5.1 Scan until the reading rises and then begins to decrease.

5.2 Reverse direction and return to the location where the maximum reading was obtained.

5.3 If the maximum reading persists for a definite distance (i.e., a tenth mile or greater), find the approximate midpoint of that distance.

6. Report the plume centerline location and maximum reading to the RACIEACC.

When reporting the location, give any landmarks which may help fix your location on a map (e.g., intersections, public buildings, streams, etc.). 7. Perform a stationary survey as described below unless directed otherwise by the RACIEACC.9 Number TMI -Unit 1 Emergency Plan Implementing Document EPIP-TMI-.10 Title Revision No. Onsite/Offsite Radiological/Environmental Monitoring 10 EXHIBIT I Page 2 of 2 B. Stationary Surveys: 1. Ensure the probe window is closed and hold the instrument probe at waist level while standing outside the vehicle.

• In inclement weather, the instrument probe should be covered with a surgeon's glove or plastic bag to keep it dry. 2. Obtain a reading by observing the instrument's needle for several seconds.

• Mentally average the needle fluctuations to arrive at an average reading.

3. Obtain 3 readings per Step 2 above over a five minute period unless directed otherwise by the RAC/EACC.

4. Record the following in Exhibit 5. 4.1 Record the 3 readings obtained per Step 3. If only 1 reading was taken, record it as "Reading 1". 4.2 If 3 readings were taken, average them and record the average.

4.3 Record the date, time and location of the reading(s).

5. Obtain one reading with the probe window open. 5.1 Record the reading (in mR/hr) in Exhibit 5. 6. Report the location, time, average closed window reading and open window reading to the RAC/EACC.10 Number TMI -Unit 1 Emergency Plan Implementing Document EPIP-TMI-.10 Title Revision No. Onsite/Offsite Radiological/Environmental Monitoring 10 EXHIBIT 2 Page 1 of 4 Radioiodine And Particulate Air Samples To perform air samples for Iodine and/or Particulate:

NOTE If possible, load the air sampler with the Silver Zeolite cartridge and particulate filter prior to entering the plume. 1. Unscrew the filter and cartridge holder rings from the air sampler head and install a new Silver Zeolite cartridge and particulate filter. 1.1 Ensure that the arrow on the side of the Silver Zeolite cartridge points toward the air sampler.

1.2 Ensure that the particulate filter is installed such that the side of the filter which has a fibrous appearance is closest to the Silver Zeolite cartridge.

1.3 Reassemble the air sampler head. NOTE The sampler flow rate, measure with both a particulate filter and a Silver Zeolite cartridge in place, is written on the air sampler's calibration sticker. The Silver Zeolite cartridge must be in place to ensure obtaining calibrated air flow rate even if an iodine sample has not been requested and the cartridge will not be analyzed in the field. 2. Ensure the following prerequisites and precautions are met: 0 The air sampler shall be placed outside the vehicle or in an open vehicle door or window. 0 Do not place the sampler on the ground or on known contaminated surfaces.

• Keep the sampler away from vehicle exhaust gases.

• Protect the sampler from rain and snow.

• All samples shall be labeled and saved for further analysis.

• Do not point the air sampler inlet toward any object which may restrict sampler air flow.

• Do not stand directly in front of the sampler inlet when the sampler is running or allow loose clothing to restrict airflow.11 Number TMI -Unit 1 Emergency Plan Implementing Document EPIP-TMI-.10 Title Revision No. OnsitelOffsite Radiological/Environmental Monitoring 10 EXHIBIT 2 Page 2 of 4 3. Using the sampler's self timer (or a stopwatch or wristwatch if the sampler is not so equipped) draw a 300 liter (approximately) air sample. 3.1 Use the table below and the sampler's posted flow rate to determine sampler run time. Sampler's with adjustable flow rate should be set to the highest flowrate possible not to exceed 50 Ipm (1.8 cfm) and run for approximate time according to the table below.

Fill out an air sample label with date, time, your name, location, air sampler run time, and air sampler flow rate. 4.1 Also record this data on Exhibit 5. 5. To evaluate the Silver Zeolite cartridge in the field, perform the following steps: 5.1 Obtain a general area background count rate with the E140N/HP260 pancake probe at approximately waist level. 5.1.1 If the background is more than 200 cpm move to a location where background is acceptable (i.e. < 200) and proceed with Step 5.2. 5.1.2 If background is 200 cpm or less, go to Step 5.3. NOTE If you cannot find an area where background is < 200 cpm, ask the RAC/EACC for advice. 5.2 At the low background area run the air sampler for approximately 3 seconds to flush the cartridge.

12 Number TMI -Unit 1 Emergency Plan Implementing Document EPIP-TMI-.10 Title Revision No. Onsite/Offsite Radiological/Environmental Monitoring 10 EXHIBIT 2 Page 3 of 4 5.3 Record the background count rate at the sample counting location on the sample label and on Exhibit 5. 5.4 Remove the cartridge from the sampler head and place it in a ziplock bag. NOTE Surgeons gloves should be used if the cartridge must be handled and contamination is expected.

5.5 Count both sides of the Silver Zeolite cartridge through the ziplock bag. 5.5.1 Record the higher count rate as "gross cpm" on the sample label and on Exhibit 5. 5.6 Subtract the background cpm from the gross cpm and record the result as "Net Cpm" on the sample label and on Exhibit 5. 5.7 Place the sample label in the ziplock bag and retain the sample for later analysis.

6. To evaluate a particulate filter in the field, perform the following steps: 6.1 Obtain a general area background count rate with the E140N/HP-260 pancake probe at approximately waist level. 6.2 If the background count rate is more than 200 cpm move to a location where background is acceptable (i.e. _< 200 cpm). NOTE If you cannot find an area where the background is < 200 cpm, ask the RAC/EACC for advice. 6.3 Unscrew the filter holder section of the sampler head from the silver zeolite cartridge holder section such that the particulate filter is held in place in the removed section.

6.4 Obtain a gross count rate on the particulate filter by holding the collection side of the filter holder against the HP-260 pancake probe. 6.5 Record the count rate as gross CPM on the sample label and on Exhibit 5. 6.6 Unscrew the retainer ring from the filter holder and, using tweezers, remove the filter from the holder. 6.7 Place the filter in the coin envelope.

6.8 Place the coin envelope in a ziplock bag (if an iodine sample was taken, use the same ziplock bag).13 Number TMI -Unit 1 Emergency Plan Implementing Document EPIP-TMI-.10 Title Revision No. Onsite/Offsite Radiological/Environmental Monitoring 10 EXHIBIT 2 Page 4 of 4 6.9 Reinstall the retainer ring onto the filter holder and re-count the filter holder without the particulate filter in place. 6.9.1 Enter this count rate as Background CPM on the sample label and on Exhibit 5. 6.10 Subtract Background CPM from Gross CPM and record the results as NET CPM on the sample label and on Exhibit 5. 6.11 Place the sample label in the ziplock bag and retain the sample for later analysis.

• See for estimation method next page 18 TMI -Unit 1 Emergency Plan Imnlementina Document WTitle Onsite/Offsite Radiological/Environmental Monitorng EXHIBIT 6 Number EPIP-TMI-.10 10 Page 2 of 2 A rough approximation of the iodine derived air concentration (DAC), thyroid dose (CDE) and internal whole body dose (CEDE) can be obtained using the following relationship:

Every 1000 net cpm on the silver zeolite cartridge equals roughly: 20 DAC Iodine, 500 mREM/hr Thyroid Dose (CDE) and 15 mREM/hr Internal Whole Body Dose (CEDE) For example: 5000 net cpm on the cartridge would roughly equal: 100 DAC Iodine, 2500 mREM/hr CDE and 75 mRERM/hr CEDE. NOTE 1. This information is intended for field team use only and not for making dose projections for the public. 2. The relationships shown above are valid only if the sampler run times specified in the sampling instructions are followed.

3. The relationships are based on conservative assumptions (e.g. all iodine is 1131) and will in most cases overestimate the field team's dose. More refined estimates can be obtained from the RAC or EACC.19 NOTE Notify the RAC/EACC when any team member approaches either of the following:

Most people get the iodine they need from foods, like iodized salt or fish. The thyroid can "store" or hold only a certain amount of iodine. In a radiation emergency, radioactive iodine may be released in the air. This material may be breathed or swallowed.

It may enter the thyroid gland and damage it. The damage would probably not show itself for years. Children are most likely to have thyroid damage. If you take potassium iodide, it will fill-up your thyroid gland with non-radioactive iodine. This reduces the chance that radioactive iodine will enter the thyroid gland. WHO SHOULD NOT TAKE POTASSIUM IODIDE The only people who should not take potassium iodide are people who know they are allergic to iodide. You may take potassium iodide even if you are taking medicines for a thyroid problem (for example, a thyroid hormone or anti-thyroid drug). Pregnant and nursing women and babies and children may also take this drug. HOW AND WHEN TO TAKE POTASSIUM IODIDE Potassium Iodide should be taken as soon as possible after proper authorization is received.

You should take one dose every 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />. More will not help you because the thyroid can "hold" only limited amounts of iodine. Larger doses will increase the risk of side effects. You will probably be told not to take the drug for more than 10 days. Contact company medical personnel to determine how long you should take potassium iodine. SIDE EFFECTS Usually, side effects of potassium iodide happen when people take higher doses for a long time. You should be careful not to take more than the recommended dose or take it for longer than you are told. Side effects are unlikely because of the low drug dose and the short time you will be taking the drug. Possible side effects include skin rashes, swelling of the salivary glands, and "iodism" (metallic taste, burning mouth and throat, sore teeth and gums, symptoms of a head cold, and sometimes stomach upset and diarrhea).

A few people could have an allergic reaction with more serious symptoms.

These could be fever and joint pains, or swelling of parts of the face and body at times severe shortness of breath requiring immediate medical attention.

Taking iodide may rarely cause overactivity of the thyroid gland, underactivity of the thyroid gland, or enlargement of the thyroid gland (goiter).

WHAT TO DO IF SIDE EFFECTS OCCUR If the side effects are severe or if you have an allergic reaction, stop taking potassium iodide and contact the medical department.

The radio will perform a "power up self test" and then display: Its unit number (e.g., "TMI P 1" is portable radio #1) and Either "EARS" or "CC SCAN" depending on whether the radio is receiving the system Control Channel signal (i.e., if "CC SCAN" appears, the radio is out of range or in a bad location).

B. To transmit:

Make sure that "EARS" is displayed on the front of the radio and then press the Push-To Talk (PTT) button (elongated button on the left side of the radio). When the short medium pitch beep is heard, begin speaking.

If a high pitch beep is heard when the PTT is pressed, the system is temporarily busy. Don't release the PTT button -continue pressing it and wait for the short medium pitch peep before starting to speak. The delay should typically be not more than a few seconds.

When speaking, hold the radio approximately 3 inches from the mouth and speak in a normal voice. C. Receiving:

When a call is being received the calling station's identity is displayed in the upper line of the radio's display.24 TMI -Unit 1 Emergency Plan Number Implementing Document EPIP-TMI-.10 Title Revision No. Onsite/Offsite Radiological/Environmental Monitoring 10 EXHIBIT 10 Page 2 of 2 D. System status beeps: The radio will indicate system status by emitting any of several beeps: A short medium pitch beep indicates that the radio has begun to transmit and the user may begin speaking.

A high pitch beep indicates that all system channels are busy and the radio is waiting for the next available channel. The user should continue pressing the PTT button until a short medium pitch beep is heard and then becqin speaking.

If five short high pitch beeps are heard while transmitting, this indicates that the radio is approaching its 60 second transmission length limit. Unless the radio is un-keyed before the long low pitch beep is heard, the radio will stop transmitting and information will be missed. Long transmissions should be broken into several shorter transmissions to avoid this. A low pitch beep simultaneous with the appearance of a battery icon in the lower right comer of the display indicates that the battery voltage is low and the battery should be changed.

E. To replace the battery pack: Turn the radio off. Depress the recessed button beside the belt clip on the rear of the radio and slide the battery toward the bottom of the radio. Lift the battery up and away from the radio. To install a fresh battery pack: Align the tabs on the battery with the slots on the radio and slide the battery pack toward the top of the radio until it clicks. F. The channel selector knob and the buttons on the front panel of the radio serve no function and should not be manipulated.
