4.0 RESPONSIBILITIES 4.1 Shift Manager/Emergency Director (SM/ED)

The SM/ED is responsible for ensuring that Protective Action Recommendations (PARs) are developed in accordance with this procedure.

Rev. No. 34 Page 4 of 26

DOSE ASSESSMENT CALCULATIONS EAP-4 4.2 TSC Rad Support Coordinator (TSC RSC)

The TSC RSC is responsible to the Emergency Director for managing the radiological monitoring and assessment aspects on-site and in-plant during an emergency and of those functions specified in Step 4.3 until relieved of those functions by the EOF.

4.3 EOF Rad Support Coordinator (EOF/RSC)

The EOF/RSC is responsible to the Emergency Director for managing the radiological monitoring and assessment aspects offsite during an emergency.

4.4 Dose Assessment Coordinator (DAC)

The DAC is responsible for managing the offsite dose aspects of an emergency, in order to assess the radiological consequences to the public.

4.5 Chemistry Technician/Rad Protection Technician The on-shift chemistry technician is responsible to the Emergency Director for conducting dose assessment from the control room and assisting the SM/ED with information related to offsite notification and protective action recommendations. The on-shift radiation protection technician is responsible to the SM/ED for conducting surveys as directed.

5.0 PROCEDURE 5.1 Control Room Dose Assessment and Protective Action Recommendations Utilize Attachment 1, Initial Protective Actions, for control room dose assessment and protective action recommendations.

Rev. No. 34 Page 5 of 26

DOSE ASSESSMENT CALCULATIONS EAP-4 5.2 Augmented Dose Assessment Dose projection shall be completed using the EDAMS computer located in the Control Room, Technical Support Center or Emergency Operations Facility as follows:

5.2.1 General Information A. Locations EDAMS software and hardware is located as follows:

METE DATA LOCATION HARDWARE PRINTERS CONNECTION Control Room Personal HP LaserJet Direct Connect Computer and Monitor _

Technical Personal Seiko D-Scan, Direct Connect Support Center Computer and HP LaserJet Monitor Emergency Personal Seiko D-Scan, Direct Connect Operations Computer and HP LaserJet OR Dial-up Facility #1 Monitor Modem Emergency Personal HP LaserJet Direct Connect Operations Facility #2 Computer and Monitor B. Computer problems OR Dial-up Modem P1 IF at any time problems are experienced with the computer, MOVE to another location that has the EDAMS software and continue.

C. The dose assessment program is called RADDOSE V and is part of the EDAMS package.

D. Meteorological data is automatically sent (via direct connect or modem) to RADDOSE V and EDAMS by the Meteorological Monitoring System (MMS). The user can use this data or manually input meteorological data.

E. Source term and release rate determination is discussed in procedure EAP-4.1.

F. Software documentation is available for the EDAMS code and is maintained by the Emergency Planning Coordinator.

Rev. No. 34 Page 6 of 26

DOSE ASSESSMENT CALCULATIONS EAP-4 5.2.2 EDAMS Dose Model Limitations A. The EDAMS menu from the EDAMS icon only allows the operation of one DOS application at a time.

B. Dose rates and deposition rates reported by the model are the maximum for the sector; not necessarily the dose rate or deposition rate at the center of the sector. This avoids the situation of a narrow (stable) plume slipping between receptor points and being missed.

C. Deposition data reported is not intended for an environmental evaluation; its intent is to indicate areas of potentially high ground level concentrations.

D. Forecast mode results may at times exceed real-time results; this is due to the forecast mode having a greater internal time step.

E. A calculation limitation of the dose assessment model occurs when an extreme wind (direction) shift takes place. The model may not calculate doses in sectors that the plume skips over entirely within a single 15 minute interval advection step.

5.2.3 Dose Assessment Using EDAMS Computer NOTE: The dose assessment model has many capabilities beyond those used in this procedure. Utilize the "EDAMS Operators Manual" for further reference.

CAUTION:

Protective Action Recommendations (PARs) must be transmitted to the State and County within 15 minutes of declaring an Emergency, changing emergency classification, or changing Protective Action Recommendations.

A. IF during the course of dose assessment, the dose to the population is projected to exceed 1 Rem TEDE or 5 Rem CDE Thyroid, THEN immediately advise the ED

- that the General Emergency criteria have been met.

Rev. No. 34 Page 7 of 26

I DOSE ASSESSMENT CALCULATIONS EAP-4 5.2.3 cont'd NOTE: Attachment 1 may be used to develop protective action recommendations from the TSC/EOF prior to EDAMS becoming available.

10. Select "Print Complete Dose/Dose Rate Report".

Rev. No. 34 Page 11 of 26

DOSE ASSESSMENT CALCULATIONS EAP-4 5.2.3 cont'd NOTE: Performance of the following step is necessary to ensure that "forecasted" dose will account for dose from both the current release rate, AND dose from the plume established in the environment from previous time steps.

11. IF the release is ongoing, THEN add a new time step, AND repeat the "Calculation" and "Forecast" actions described in steps M-P.

NOTE: County and State Protective Action Recommendations (PARs) take many factors into account that NMP/JAF procedures do not (i.e., road conditions, special population needs, Evacuation Travel Time Estimates, evacuation scenarios, and shelter vs. evacuation doses). Therefore, differences in PARs may occur.

The Rad Support Coordinator must account for differences in Protective Action Recommendations when those exist. PARs should not be modified to match County or State PARs without justification.

CAUTION:

Protective Action Recommendations (PARs) must be transmitted to the State and County within 15 minutes of declaring an Emergency, changing emergency classification, or changing Protective Action Recommendations.

Q. Protective Action Recommendations (PARs)

1. Since the Nine Mile Point/J.A. FitzPatrick (NMP/JAF) Site is contained in ERPA 1, any recommendation made for ERPA 1 must also apply to all NMP/JAF personnel not required to be onsite for the emergency.
2. The RADDOSE model factors in meteorological conditions such as lake/land breeze that the Attachment 2 flowchart does not. Therefore, the model needs to be considered even during situations where no release is occurring.

Rev. No. 34 Page 12 of 26

DOSE ASSESSMENT CALCULATIONS EAP-4 5.2.3.Q. cont'd

3. The EDAMS RADDOSE V program will recommend PARs for each ERPA, based upon the dose assessment (in forecast mode).
a. Ensure that both the RADDOSE ERPAs recommended for Evacuation, and the Attachment 2 ERPAs recommended for evacuation are considered when developing PARs.
b. For ERPAs recommended by RADDOSE for evacuation, ensure that both Dose PARs and Plant PARs are included.
4. Initiate or revise PARs based upon this recommendation (and previous recommendations, if made).
5. Wind shifts and/or decreases in release rate could result in revised PARs being developed that "drop" one or more ERPAs from evacuation recommendations. HOWEVER, revised PARs must contain all previously identified ERPAs recommended for evacuation, as well as any newly identified ERPAs for evacuation, i.e.:
a. Do NOT delete ERPAs from a PAR that previously recommended the ERPA for evacuation.
b. There is no practical method to recall an evacuation recommendation and attempting this could cause undue confusion on the part of the public.
6. The only time it would be appropriate to attempt to recall a PAR for evacuation of an ERPA, would be if an error was made and recognized prior to the County taking action to implement the PAR.
a. In this case it would be appropriate for the Emergency Director to immediately contact the County and discuss the issue.

Rev. No. 34 Page 13 of 26

DOSE ASSESSMENT CALCULATIONS EAP-4 5.2.3 cont'd R. Notification

1. Record the revised PAR for each ERPA on the Part 1 Notification Form (EAP-1.1, Attachment 1) and give to the ED for approval.
2. Record PARs on Attachment 4 map or wall displays in the TSC or EOF, if appropriate.

S. Update the RADDOSE-V Model at 15-minute intervals or as directed by the Dose Assessment Coordinator.

5.3 Downwind Survey Dose Estimates 5.3.1 Use Attachment 5, Downwind Survey Worksheet, to record field data transmitted to the dispatch center.

5.3.2 Projected Deep Dose Equivalent (DDE) is approximately equal to TEDE Projected Dose A. Use field information recorded on the Downwind Survey Worksheet, Attachment 5, to perform projected dose calculations.

B. Obtain the estimated duration of release from the Emergency Director and record it on Attachment 5.

If it is unknown, use 4 hours4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br /> as a first estimate.

C. Complete the calculations, as shown, on Attachment 5 to determine DDE projected doses for each sampling location.

5.3.3 CDE Thyroid Projected Dose A. Use field information recorded on the Downwind Survey Worksheet, Attachment 5, to perform CDE Thyroid Projected Dose.

B. Obtain the estimated duration of release from the Emergency Director and record it on Attachment 5.

Rev. No. 34 Page 14 of 26

DOSE ASSESSMENT CALCULATIONS EAP-4 5.3.3 cont'd C. Calculate the I-131 concentration in accordance with Attachment 5.

D. Complete the calculations, as shown, on Attachment 5 to determine thyroid rate and CDE thyroid projected doses for each location for which data has been recorded.

5.3.4 Results A. Provide the results of the DDE and CDE thyroid projected dose calculations from steps 5.3.2 and 5.3.3 to the individual tasked with calculating protective action recommendations.

5.4 Using monitor readings to estimate when a PAR will be reached based on projected dose NOTE: Attachment 7 may be utilized to perform the following calculations:

5.4.1 To determine the estimated monitor reading needed to reach a Child Thyroid dose of 5rem CDE, perform the following:

A. Perform a forecast using EDAMS; B. Divide the Child Thyroid CDE dose (forecasted), by

-the release point monitor reading (mr/hr,cpm,cps);

C. Divide the result from 5.4.1.B into 5 rem. This result becomes the estimated monitor reading corresponding to 5rem CDE for the forecast duration, based on the inputted flow rate, monitor reading and meteorology at the time the data was taken.

D. To determine the estimated monitor reading needed to reach a TEDE dose of 1 rem, perform the following:

1. Perform a forecast using EDAMS;
2. Divide the TEDE dose (forecasted), by the release point monitor reading (mr/hr,cpm,cps);
3. Divide the result from 5.4.2.B into 1 rem. This result becomes the estimated monitor reading corresponding to lrem CDE for the forecast duration, based on the inputted flow rate, monitor reading and meteorology at the time the data was taken.

Rev. No. 34 Page 15 of 26

DOSE ASSESSMENT CALCULATIONS EAP- 4 5.5 Proactive Action Recommendations (PARs) beyond 10 miles 5.5.1 If projected doses exceed the following values at 10 miles; EPA Protective Action Guidelines TEDE (Rem) CDEt (Rem)

>1 >5 Then PARs need to be developed beyond the 10 mile EPZ.

PARs can be developed using the EDAMs routine that calculates Dose Rates at a point of interest.

5.5.2 Chose several points of interest that will encompass the postulated plume beyond the 10 miles (bound the plume). Determine the dose rate. Multiply the dose rate by the expected duration of the release to determine the TEDE or CDEt. Make additional PARs based on this data and by using existing geo-political boundaries (i.e. towns, cities, etc.). List those

.-recommendations on the Part 1 form or provide additional detail on supplemental forms. If PARs extend beyond the border of Oswego County request assistance from NY State staff to make proper notifications.

SOURCE TERM ENTRY FOR FIRST 15 MINUTE TIME STEP OF A REFUEL ACCIDENT WHEN BUILDING ISOLATON HAS OCCURRED AND THE RELEASE IS THROUGH THE STACK Page lfi 2 The following information is extracted from JEP-00-034 for entry of Refuel Accident source term for the first 15 minute time step when building ventilation occurs as expected.

BACKGROUND:

During the Design Basis Refuel Accident, there will be two release pathways. The first release pathway is through the Reactor Building Vent for eight (8) seconds.

This is a ground level, unfiltered release. The reason for this release is that isolation of the reactor building takes place in 18 seconds following the accident, and the reactor building ducting was sized to provide a ten (10) second delay. In addition, during the transition from the Normal Reactor Building Ventilation mode to the Isolated mode, a potential exfiltration activity release occurs. Exfiltration is the pressurization of the building. Radioactive gases, which escape the fuel pool, are released to the atmosphere 10 seconds after the accident for 8 seconds with a small additional release via exfiltration. The remainder of the activity which escapes the pool is released to the atmosphere via the Standby Gas Treatment System (SBGT) and the stack (elevated release) beginning 18 seconds after the accident.

ENTRY STEPS FOR FIRST 15 MINUTE TIME STEP:

The following steps should be performed to estimate the offsite dose following a refuel accident using EDAMS. In Raddose "Enter/Edit Source Term Data" Option, perform the following:

The first "time step" in the Source Term Data Entry Screen should contain two release pathways as follows:

2. On the first release path line, in the Accident type column, select "RFA -

Refuel Accident". This will insert the filtered portion of the release into the model.

a. Select "Y" for Elevated Release.
b. In the METHOD column, select "FSAR - Default Release Rate".
c. Select the appropriate Iodine method.
3. On the second release path line of time step 1, in the Accident type column, select "USER- User Defined Accident".
a. Select "N" for Elevated Release.
b. Next, enter the following isotopic data into the isotopic entry screen:

SOURCE TERM FOR A REFUEL ACCIDENT THAT RESULTS IN AN UNFILTERED RELEASE PATHWAY Page 1 cf. 1 BACKGROUND NOTE: Attachment 8 should be utilized if building ventilation isolation has occurred, and the release is being filtered through Stand-by Gas Treatment.

The following accident source term will be utilized prior to the availability of chemistry data for a refuel accident that results in an unfiltered release through either the stack, a building vent or unmonitored pathway. The information is taken from the EAP-4 Attachment 3 tab for decay time 0.0.

1. Select USER as the accident type.
2. You will be queried as to whether the release is elevated.

OBTAINING METEOROLOGICAL DATA EAP-42 4.1 cont'd.

The general methodology involved would concern providing meteorological data dependent on type of release. An elevated release (stack) would utilize 200' level data; and if unavailable, would progress in decreasing order to 100',

30' and backup tower data (90'). Likewise, a ground release (any other than stack) would utilize 30' level data, and if unavailable, would progress in increasing order to 100',

200' and backup tower data (90').

This list does not delineate a required order of priority but provides a listing of resources based on accessibility timeliness and accuracy of 15 minute averaged data.

NOTE: Flowchart (Attachment 1) is provided as a quick reference and may be utilized by the operator familiar with the body of this procedure.

It is optional to record met data on Attachment 2, Obtaining Meteorological Data for Manual Computer Input; this may provide some convenience.

4.2 Obtaining Meteorological Data from EDAMS NOTE: From the TSC, EOF, or SAS the user should Logoff disconnect) from the Met Data system when the automatic access to the data is no longer needed. This will normally be at the termination of an emergency, drill, or exercise.

4.2.1 If the EDAMS computer is on-line:

A. The computer will automatically requery the met system and update the data every 15 minutes on the quarter hour (eg. 1300, 1315, 1330, etc.). A beep may be heard when the update occurs.

B. When recording data, the operator should confirm the time and date displayed are the most current (ie.

within the last 15 minutes of the current time).

C. The operator may select "Requery" to ensure the most current data is displayed.

OBTAINING METEOROLOGICAL DATA EAP-42 4.3 Obtaining Meteorological Data from Nine Mile 4.3.1 From the Control Room, use the direct line phone to Unit 1 or 2 Control Room and request latest 15 minute averaged data.

4.3.2 If for some reason direct line unavailable, from TSC EOF or SAS, use a commercial phone with one of the following numbers:

A. NMP1: 349-2841, 349-2842 or 349-2843 B. NMP2: 349-2168, 349-2169 or 349-2170 4.4 Obtaining Meteorological Data from Analog Strip Charts 4.4.1 Description of analog strip charts and information

-available.

There are four (4) analog strip chart recorders available in the Control room and TSC to provide meteorological data.

Each of the three recorders (D, G, J) have two channels (1 and 2) to provide wind speed and direction.

Channel 1= wind speed in mph (0-100 mph) traced on left Channel 2 = wind direction in degrees(arc) (5400 range) traced on right Recorders used for wind speed and direction D Main Tower 200' level G JAF Backup Tower 90' level J Main Tower 30' or 100' level (selector switch provided)

Recorder K is provided for stability class determination.

Recorder K has the following four traces:

1 Provides temperature in OF at 30' level 2 Provides AT in 0F from 30' to 100' level 3 Provides AT in 0F from 30' to 200' level 4 Selectable sigma theta (wind direction variation)

Rev. No. 21 Page 7 of 20

OBTAINING METEOROLOGICAL DATA EAP-42 Ft Trace 4 has four selectable channels to trace for:

A High main tower (200')

B Mid main tower (100')

C Low main tower (30')

D Backup tower (90')

4.4.2 Before attempting to obtain data from any of the strip chart recorders, ensure they are functioning by verifying the date and time on the display is correct.

The strip chart runs at l"/hr. Time indicated is Eastern Standard Time.

4.4.3 When manually retrieving meteorological data, primary concern is given to wind speed and direction, and to the stability class at particular elevations, dependent on the type of release.

4.4.4 In order to properly estimate the last 15 minutes on the strip chart, measure the last 1/4" of data for each parameter, if not readily visible, and/or the chart has not already been advanced, do so in order to average the last 15 minutes of data properly. Obtain a minimum of 4 data points within that 1/4" of chart and average.

4.4.5 Meteorological data for a Ground or both a Ground and Elevated release are to be determined as follows:

A. There are 3 recorders, which record wind speed and direction (Recorders D, G, and J). For each chart, wind speed (the left trace) is labeled Channel 1 and is in MPH (the range is 0 to 100 MPH and spans the left side of the chart) and wind direction (the right trace) is labeled Channel 2 and is in degrees arc (the range is 0 to 540 degrees and spans the right side of the chart). Consult Attachment 4.

To obtain wind direction and speed for a ground or ground and elevated release, you must first determine whether the Recorder "J" toggle switch is set for 30 or 100 foot (Main Tower). If it is set for 30 foot (Main), average the wind speed and direction as per step 4.4.5.

If the Recorder "J" toggle switch is set for 100 foot (Main Tower) and/or there is no 30 foot data, adhere to the following hierarchy of substeps:

Rev. No. 21 Page 8 of 20

OBTAINING METEOROLOGICAL DATA EAP-42 4.4.5 cont'd

1. Average the wind speed and direction as per step 4.4.5 for Recorder "G", which is meteorological data for the JAF Back-up Tower 90 foot level.
2. If Recorder "G" is inoperable average the wind speed and direction as per step 4.4.5 for Recorder "D", which is meteorological data for the Main Tower 200 foot level.
3. If both Recorder "G & D" are inoperable average the wind speed and direction as per step 4.4.5 for Recorder "J" which is meteorological data for either the 30 or 100 foot Main Tower levels, as determined by the toggle switch position.
4. If NO strip chart wind speed and direction data is available, proceed to section 4.5 after completing 4.4.8.

4.4.6 Meteorological data for an elevated release is to be determined as follows:

A. There are 3 recorders, which record wind speed and direction (Recorders D, G and J). For each chart, wind speed (the left trace) is in MPH (the range is 0 to 100 MPH, and spans the left side of the chart) and wind direction (the right trace) is in degrees arc (the range is 0 to 540 degrees and spans the right side of the chart). Consult Attachment 4.

To obtain wind speed and direction for an elevated release, adhere to the following substeps:

1. Average the wind speed and direction as per step 4.4.5 for Recorder "D", which is meteorological data for the Main Tower 200 foot level.
2. If Recorder "D" is inoperable average the wind speed and direction as per step 4.4.5 for Recorder "G", which is meteorological data for the JAF Back-up Tower 90 foot level.

4. If NO strip chart wind speed and direction data is available, proceed to section 4.5 after completing 4.4.8.

4.4.7 To determine stability class for either a ground or elevated release, you must utilize Recorder "K" information, which contains 4 channels that span the full chart:

NOTE: Prior to declaring the TSC Operational, POSTED ATTACHMENT A, EXAMPLES OF ATMOSPHERIC STABILITY may be used in the Control Room and/or TSC to provide quick stability class estimation to meet offsite agency notification requirements.

A. Trace labeled "1" provides ambient temperature, on a

-40 to +110 scale and indicates the current temperature in degrees F at the Main Tower 30 foot level.

B. Trace "2" provides temperature difference (delta T) between the 30 and 100 foot level on the Main Tower, and is on the -8 to +20 scale in degrees F.

C. Trace "3" provides temperature difference between the 30 and 200 foot level on the Main Tower, and is on the same -8 to +20 scale in degrees F.

D. Trace "4" provides sigma theta (wind direction variation), on a scale of 0 to 30 degrees, at a level dependant on the switch position on the front of the TIGRAPH recording panel:

Switch Position Level Tower A 200 ft. Main (Primary)

B 100 ft. Main (Primary)

C 30 ft. Main (Primary)

OBTAINING METEOROLOGICAL DATA EAP-42 4.4.8 To derive stability class for either a ground or elevated release, or both, utilize Attachment 4 and adhere to the following hierarchy of substeps:

A. Average the trace "4" (sigma theta) on Recorder "K",

utilizing the 0 to 30 scale, as per step 4.4.5, noting the switch position, and consulting Attachment 6 to determine letter stability class.

NOTE: If data is invalid, you may want to switch another switch position to get the most representative data (for the next 15 minute average). For example, for an elevated release you should utilize switch position A, then B, D and finally C, and for a ground release, the progression is C, B, D and then A.

B. If Trace "4" is unavailable, average the Trace "3' (temperature difference 30 - 200 foot) on Recorder "K", utilizing the -8 to +20 degree F scale as per step 4.4.5 and consulting Attachment 6 to determine letter stability class.

C. If Traces "4" and "3" are unavailable, average the Trace "2" (temperature difference 30 - 100 foot) on Recorder "K", utilizing the -8 to +20 degree F scale as per step 4.4.5 and consulting Attachment 6 to determine letter stability class.

D. If Traces "4","3", and "2"" are unavailable, estimate stability by comparing wind direction and speed traces to the samples posted on the side of the TIGRAPH 200 housing and/or utilizing the "Atmospheric Stability Characterization" table on Attachment 6.

E. If All Recorders are unavailable for meteorological data, proceed to section 4.5.

4.5 Obtaining Meteorological Information From Other Sources 4.5.1 If meteorological data is not obtained via the primary method (digital) or secondary method (analog strip charts) information on local wind speed and direction, and stability class can be obtained through other sources.
