Title:

Emergency Dose Projection System Operations Page: 4 of 32 1.0 PURPOSE This procedure provides instructions for the use of the computerized dose projection system Unified RASCAL Interface (URI) to predict offsite dose rates, integrated doses and radioactive material deposition for .locations within the 10-mile Plume Emergency Planning Zone (EPZ) and the 50-mile Ingestion EPZ. Actual manipulation of system display terminals is described in document MAN-URl-01 referred to as the URI User's Manual. {R-1594}

The dose projection system is used for estimating the whole body (TEDE) and thyroid (COE) doses of onsite and offsite persons in the event of potential or actual accidental release of radioactivity to the environment. The dose projection system used at Columbia consists of a computer software program that relies on pre-calculated, real time; site-specific relationships between effluent monitor readings (or sample results) and on-site and offsite dose rates.

The dose projection system is available in the Control Room, TSC, EOF, and Alternate EOF.

Having the dose projection system software loaded on multiple, stand-alone computers located in the various emergency centers maximizes dose projection capability. Field Team data may be used to calculate dose projections or validate previous projections.

The software program supports a rapid version of dose projection using limited pathways for a rapid evaluation of the release out to 1O miles. The software also supports a detailed dose projection based on more detailed pathways with dose projections from the site boundary out to 1O or 50 miles.

State and county organizations will have access to this system in the EOF or by transmission of output information to their emergency centers.

2.0 DEFINITIONS 2.1 COE Thyroid - Committed Dose Equivalent to the thyroid.

2.2 Delta T - The temperature difference between two sensors located at different elevations on a meteorological tower.

2.3 EDE to TEDE Ratio (EDE/TEDE) - Ratios computed by URI that are used for determining the Emergency Worker Dose Adjustment Factor. The EDE is the external gamma dose that is normally monitored by emergency workers through their self-reading dosimeters (electronic dosimeters or pocket-ion chambers); and TEDE is the total dose from both EDE and the internal dose from inhaled iodines and particulates.

2.4 Elevated Release - An effluent release point model that assumes that the release point is from a discreet true elevated (tall) stack.

2.5 Emergency Worker Dose Adjustment Factor (EWDAF) - An adjustment factor determined from the EDE/TEDE Ratio that is used by offsite emergency workers to monitor their TEDE whole body dose based on their EDE doses as measured on their self-reading dosimeters. The adjustment factor is the inverse of the EDE/TEDE Ratio reported by URI (for example, an EDE/TEDE Ratio of 0.15 would mean that the EWDAF is 1 / 0.15 = 6.7) .

Title:

Emergency Dose Projection System Operations Page: 5 of 32 2.6 Radioactive Release - A radioactive release is in progress when:

Effluent monitors indicate an increase in radiation levels from normal readings for plant operating conditions, or Field teams detect environmental radiation 1O times greater than normal background.

AND.

The increased levels are attributable to the emergency event.

2.7 Radioactive Release Termination -A radioactive release is terminated when the following criteria have been met:

1. The source of the release has been isolated;

2. The effluent monitors are trending downward (if available);

3. Environmental Field Team surveys indicate a decrease in radiation levels or airborne radioactivity.

2.8 RASCAL - NRC supported and distributed computer software for determining source term, atmospheric dispersion, and dose consequences.

2.9 Site Boundarv (SB) - Closest distance between owner controlled area boundary and core, set

• 2.1 O 2.11 at 1.2 miles .

Source Term - The quantity and radionuclide makeup of the material in the release. The source term used in URI is based on NUREG-1228.

Stability Class - Values from A to G representing ranges of Delta T which in turn represent atmospheric mixing estimations. The NRC definitions of these ranges are used to define the stability classes used in URI.

2.12 Stack Door Monitor (SOM) -A portable radiation survey meter (e.g., Teletector) or radiation monitoring instrument (e.g., AMP-100) used for monitoring radiation levels at the exterior and center of the Elevated Release Stack Access Door (R-DOOR-R515). This provides an alternate means for monitoring Reactor Building post-accident effluent releases when the installed Stack Monitors (PRM-RE-1B and/or PRM-RE-1C) are inoperable or unavailable.

SOM readings (in mR/hr) are available from HP; or, when set up for remote monitoring, through eDNA Real-Time Client or eDNA Trend from eDNA Point IDs EP99M (mid-range SOM) and EP99H (high-range SOM) in the ENW.WRM Service.

2.13 TEDE - Total Effective Dose Equivalent (TEDE) - The sum of the Deep Dose Equivalent (ODE) and the Committed Effective Dose Equivalent (CEDE).

2.14 Unified RASCAL Interface (URI) - Computer software which replaces the NRC issued RASCAL user interface for user input of dose assessment parameters and interpretation of results that interfaces to the RASCAL meteorological and dose processor modules.

3.3 Chemistry Effluent Manager Once the TSC is manned, the Chemistry Effluent Manager is responsible for performing dose assessments if required for the TSC.

4.0 PROCEDURE

4. 1 General Instructions 4.1.1 If in a declared emergency and an offsite dose or dose rate projection is needed, or if so directed, use URI to perform offsite dose calculations.

4.1.2 Access the Plant Data Information System (POIS) through the electronic Distributed Network Architecture (eDNA) software to obtain and monitor key radiation monitor, meteorological, and Plant effluent data.

a. At a LAN supported computer:

1) Double click on the "eDNA View" icon on the Desktop, if available. If no "eDNA View" icon is available, open eDNA through the network folder and select eDNA View.

2) Select CGS, then "POIS", and "Rad Status" to obtain the "Radiological Status" screen.

• A screen print of the "Radiological Status" screen may be used to capture the current values of radiation monitor, meteorological, and effluent data for tracking changes (setup printer to Landscape mode, and use the "Print Direct" function rather than "Print" from the "File" drop-down menu on the eDNA View "Radiological Status" screen or if the file menu is not available, right click the eDNA screen and select "Print Direct").

• Access other eDNA View screens of POIS data by selecting the appropriate "eDNA View (*.rtv)" in the Application Service Utility window, as desired.

• Graphical trends of the plant parameters displayed on the eDNA View screens can be displayed by clicking in the appropriate plant parameter display box. The time span of the graphical trend may be modified by selecting "Modify Graph Parameters" in the "Graph" pull-down menu, selecting the "Graph" tab, and entering the desired date and time range (click to check the "Y-Axis Auto Scale" box for a clearer graph).

3) Radiation monitor, effluent monitor, SOM, and meteorological data are also available through other eDNA applications (e.g., eDNA Real-Time Client or eDNA Trend) from the Start menu/All Programs/eDNA folder and selecting

• the appropriate ENW Service (e.g., ENW.CGS, ENW.WRM, etc.) .

Title:

Emergency Dose Projection System Operations Page: 7 of 32 4.1.3 Use URI to estimate doses within 15 minutes of a start of a release or as information becomes available. Also use URI to estimate offsite dose during rapidly changing meteorological conditions or release conditions as appropriate.

4.1.4 Start URI by double-clicking on the appropriate icon on the Desktop or start from the "C" drive.

4.1.5 If necessary, refer to Attachment 7 .1, URI User Guidance, which provides detailed guidance on using URI.

4.1.6 Review dose projection printouts, note any qualifying factors as appropriate and brief the RPM or REM on the dose projection.

4.1.7 In the EOF/TSC, if any data is suspect, request the Radiation Detection System Engineer or the EOF/TSC Information Coordinator to verify the data.

4.1.8 In the event of unmonitored release paths or if instrumentation (including alternate instrumentation) is out of service or off-scale, Field Team results are used to calculate dose projections. Use one of the following processes to assess Field Team results: *

a. Air sample Excel spreadsheet calculator found on the Window Desktop

1) Enter the cartridge and background readings, and press the tab key to perform the calculation.

b. Attachment 7.2, Air Sampling Worksheet Calculation

1) Enter sample and background count rate and sample volume into calculations to determine micro curies/cc.

c. Air Sample Calculator in URI Detailed assessment (preferred)

Title:

Emergency Dose Projection System Operations Page: 8 of 32 4.1.9 Provide the Emergency Worker Dose Adjustment Factor to the REM and Field Team Coordinator for their use in establishing field team exposure limits.

a. If the Dose Adjustment Factor is 5 or greater, use Dose Adjustment Factor of 5.

b. On page three of the detailed Dose Assessment Report invert the EDE/TEDE ratios to acquire the Dose Adjustment Factor. Use the EDE/TEDE Ratio with Iodine. If respiratory protection or a thyroid blocking agent (i.e., potassium

• iodide) is being used, then it may be appropriate to use the EDE/TEDE Ratio without Iodine.

Example:

EDE/TEDE ratio with iodine at 2 miles is 0.90 the Emergency Worker Dose Adjustment Factor would be 1.1. (1 divided by 0.9)

c. If the EDE/TEDE ratio is less than or equal to 0.2, use a Dose Adjustment Factor of 5.

4.1.10 If any of the TEDE or COE values are greater than or equal to the levels in the below table on a release, the ED should refer to PPM 13.1.1 for the appropriate classification.

1.8 Notes

Stack Door Monitor (SOM) is a direct monitored input option. FFTF delta-Tis a direct input for stability class. CGS has committed to performing ground release assessments; so only ten meter Met conditions should be selected.

During the ingestion phase, determine manual contour lines on the 10-50 mile map by selecting grid and balloon options to determine the projected 500 µR (relocation boundary),

20 µR and 0.4 µR (food control boundary).

2.0 Rapid URI Activate Rapid URI by selecting the Rapid option (upper right hand corner) on the URI main screen. The Rapid Assessment page is now available for data input.

2.1.1 Source Term Grouping (this grouping provides input on what type of damage to the fuel has occurred)

a. In the Source Term box, answer the initial question concerning Fuel Clad Damage. If damage to the core is suspected (PPM 13.1.1 Table 3 Effluent Monitor reading is GT UE value), select "yes". This causes the assessment to include isotopic mix and inventory for fuel clad damage.

b. Selecting Fuel Clad Damage "No" causes selection of normal coolant concentrations as the basis of the source term. This also activates the Conditions for Coolant Spiking question. Select "Yes" if Reactor Bldg process radiation monitors spike following a plant transient; otherwise select "No".

c. Check the "Reactor Shutdown" box if appropriate and enter date of shutdown

• using the pull down calendar. Overwrite the indicated time as necessary .

The radiation level readings (in mR/hr) from this Stack Door Monitor (SOM) can be converted to an equivalent PRM-RE-1B (RB Stack Intermediate Range) or PRM-RE-1C (RB Stack High Range) reading (in cps) that can be input into the Monitor Reading field in URI to perform a dose projection.

The technical basis for this SOM to PRM equivalency can be found in Engineering Calculation NE 12-05. The use of the table may be used for Table 3 equivalency if needed.

Data from eDNA Points EP99M (mid-range SOM, 5 mR/hr to 1E6 mR/hr) and EP99H (high-range SOM, 1000 mR/hr to 1E7 mR/hr) is updated approximately every minute and is displayed in mR/hr.

Emergency Dose Projection System Operations Page: 30 of 32 Alternate Method for TEA-RIS-13 or WEA-RIS-14 Compensatory Noble Gas Monitor (CNGM) sample cart(s) will be available to measure radiation levels as a compensatory measure when the normal sample racks for TEA-RIS-13 and/or WEA-RIS-14 are unavailable. There is one cart for TEA, and a different cart for WEA readings. While the equations below apply directly to the readings from either cart, it is critical to ensure that the WEA cart readings are only used for WEA dose assessments and TEA readings be used for TEA dose assessments. IF both WEA and TEA are non-functional, then both carts will be in operation and the dose assessments must be derived from the respective cart.

The technical basis for this compensatory measure equivalency can be found in RSCS TSD-13-035 (CVI 1057-00, 131). The conversion equations below are used for calculating equivalent inputs for URI. Data from the CNGM will be available to the Main Control Room for monitoring a release during this compensatory measure. There is a slide at the frisker which is inserted for normal readings LTE 400,000 cpm and withdrawn for readings GT 400,000 cpm.

1) !E URI is unavailable, THEN use Table 3 of PPM 13.1.1 to classify.

2) IF frisker reading is GT 400,000 cpm, THEN direct Chemistry to withdraw the CNGM slide.

3) If calculating TEA values to input into URI, then use the following conversion factors, otherwise NIA this step:

• !E TEA frisker reading is LTE 400,000 cpm, slide inserted (Low Range Input) THEN TEA URI INPUT (µCi/cc)= [Frisker output (cpm)] / 1.01E7 cpm/µCi/cc Example: the frisker reading obtained from the sample cart is 80,000 cpm. The equivalent URI input for either TEA or WEA would be:

TEA 80000 cpm divided by 1.01 E7 cpm/µCi/cc =7.92e-3 µCi/cc Enter this value into URI for the TEA monitor.

• !E frisker slide is withdrawn, THEN TEA URI INPUT (µCi/cc)= [Frisker output (cpm)] I 3.87E6 cpm/µCi/cc

4) If calculating WEA values to input into URI, then use the following conversion factors, otherwise N/A this step:

• !E WEA frisker reading is LTE 400,000 cpm, slide inserted (Low Range Input) THEN WEA URI INPUT (µCi/cc)= [Frisker output (cpm)] / 1.01E7 cpm/µCi/cc

NOTE: Wireless Radiation monitors cannot be used in the Main Control Room. In the event ARM-RIS-19 is disabled, notify HP to install a non-transmitting portable area radiation monitor with an alarm set-point of 15 mr/hr.

NOTE: In the event of unplanned ARM failures, an hourly H.P. tour of the affected.

areas should be established until the measures of this attachment are established .

2.0 CONTROL ROOM PERSONNEL:

2.1 Direct HP to establish the applicable compensatory measures as per this attachment.

2.2 During this evolution, area radiation levels will be provided as follows:

• HP will have established wireless remote monitors into each of the areas affected, in accordance with the requirements of PPM 11.2.9.32. These monitors will provide indication to a remote monitor in the HP access area.

• In the event an area radiation level meet or exceed an ARM set-point identified by PPM 4.602.AS, the Control Room will be notified immediately. These indications should be treated as actual ARM indications. Consider directing continuous monitoring. The Control Room will be notified. immediately of instrument failure.

• In the event of an emergency classification of ALERT or higher, this information will be available by request of the TSC. Continuous monitoring is not required.

• In the event that OG-RIS-612 has been replaced with an area radiation monitor, EAL classification can be made based on area radiation monitor indication that is equivalent to OG Pretreatment Hi-Hi alarm. Refer to ODCM 6.1.2.1 .

3.2 For OG-RIS-612, establish the compensatory measures, in accordance with ODCM 6.1.2.1.

3.3 Ensure a knowledgeable individual is stationed at a monitor to observe the read-outs from each of the wireless remote monitors. Also ensure telephone communication is established with the Control Room.

3.4 Provide direction to the knowledgeable individual to ensure the following is clearly understood:

• The radiation indications to be monitored.

• Until released by the Control Room, remain available. Check the remote monitor radiation levels at least every 15 minutes. This may be more frequent or continuous, as directed by the Control Room.

o Notify the Control Room if radiation levels on any monitor increase above an ARM set-point or 1O R/hr.

o Provide the detector locations and the radiation levels observed.

o Make an HP log entry of the notification and information transmitted .

o If a monitor indication fails (excluding "LOST CONTACT" for less than 10 minutes),

IMMEDIATELY notify the Control Room.
