of 84 1.0 PURPOSE To describe the methods of estimating the whole body and thyroid doses to onsite and offsite persons in the event of potential or actual accidental release of radioactivity to the environment

2.0 REFERENCES

2.1 MIDAS user manual (ABS Consulting) 2.2 IP-EP-510, Meteorological, Radiological & Plant Data Acquisition System 2.3 IP-EP-410, Protective Action Recommendations 3.0 DEFINITIONS 3.1 MRPDAS - Meteorological, Radiological, and Plant Parameter Data Acquisition System - the system which provides meteorological, Reuter Stokes and certain plant parameter data (VC Temperature, VC Pressure, Plant Vent and VC High Radiation Monitors) 3.2 Total Effective Dose Equivalent (TEDE) - The sum of the Deep Dose Equivalent (DOE) and the Committed Effective Dose Equivalent (CEDE).

3.3 Committed Dose Equivalent Thyroid (COE Thyroid) - The dose equivalent to the thyroid that will be received from an intake of radioiodine by an individual during the 50-year period following the intake.

3.4 CEDE - Committed effective dose equivalent is the sum of the products of the weighting factors applicable to each of the body organs or tissues that are irradiated and the committed dose equivalent to these organs or tissues 3.5 Site Boundary - For Dose Assessment and Protective Action Recommendation purposes the Site Boundary is the closest distance at which members of the public would be exposed to a radioactive release. When the plume is traveling toward the water, the distance to the nearest point on the far shore is used.

3.6 MIDAS - Meteorological Information and Dose Assessment System - computer software for determining source term, atmospheric dispersion, and dose consequences 3.7 Source term - generic term for curies available for release or actually being released. 'Term' in mathematics is any single factor in an equation. Hence

'source term', 'dispersion term', etc are simply portions of the equation for the calculation 3.8 Ground level release - an effluent release point model that assumes that the release point is at ground level, with no accounting for the additional mixing from other release point factors such as height above the ground, plume temperature, and exit velocity

.1 of 84 3.9 Multiple Accident Run - Allows for dose calculations for accident releases occurring simultaneously from different release locations at one or both units.

4.0 RESPONSIBILITIES Dose Assessment staff in the Control Room (CR) and in the Emergency Operations Facility (EOF) are responsible for assessing actual and potential planned and unplanned radioactive releases to the environment. Attachments at the end of the procedure may be used as a reference when stepping through a MIDAS dose assessment calculation.

NOTE:

When a dose assessment is being performed you may proceed directly to the applicable attachment in the procedure for the type of dose assessment being performed.

5.0 DETAILS 5.1 MIDAS is a menu driven computer system - menus are described below throughout Section 5 5.2 Step by step option selection for each menu are shown in the attachments 5.3 MIDAS uses a segmented plume model with terrain and meteorology specific wind fields. Displayed plumes are EXPECTED to have unusual shapes. (See Section 5.12) 5.4 MIDAS also uses an automated plant data collection system 'NDCIP' which runs in the background on the MIDAS computer 5.5 MIDAS Startup 5.5.1 PC computer system should be running with the program "NDCIP" active NOTE:

NDCIP provides the automated interface between the plant data sources (e.g. Pl computer) and the MIDAS system for automated plant monitor and meteorological data collection and should not be closed by the user.

NOTE:

If NDCIP is not already active in the computer, it will start when MIDAS is started. In this case, there will not be recent history or current automated data available until a data collection cycle is completed.

5.5.2 Start MIDAS by 'double-clicking' on the 'MIDAS Accident Cales' icon

a.

'Recap Previous Run' near the bottom left is the alternate button selection for 'Start New Run'

b.

'Recap Previous Run' allows display of previously saved runs from the list at the bottom of the page

c.

'Recap Previous Run' will generally not be needed in the initial phase of dose evaluation but can be used if hard copy printouts of a previous run are needed 5.5.6 Select the appropriate Unit (2 or 3) on the upper right

a.

If more than one location is experiencing a release, a calculation must be completed for each location.

(ex. Unit 2, Unit 3, Spent Fuel Pool) 5.5.7 Select your location CCR or EOF 5.5.8 Select Automatic, Manual, or Simulation NOTE:

Automatic should be selected whenever possible unless it is KNOWN that the automated data is wrong, unavailable, or misleading.

NOTE:

Simulation uses automated DRILL data. Simulation should be selected whenever possible during DRILLS unless it is KNOWN that the automated drill data is wrong, unavailable, or misleading.

NOTE:

Choosing 'Automatic' will force MIDAS to use any of the effluent and radiation monitor data and meteorological data automatically collected from the plant computer system (Pl computers). Manual will cause MIDAS to IGNORE this available data and will REQUIRE the user to obtain and enter this data by hand.

5.5.9 Based on the choices of CCR/EOF and Automatic (Simulator)/ Manual the list of available choices in the 'Accident Run Menu Selection' will change

b.

Menu H - Auto Enhanced dose projection -this menu uses automatically loaded data but allows the user to select relevant release points and other parameters

c.

Menu I - Auto Met Event Tree - uses automatically loaded meteorological data but uses a pull down event tree selection process to determine source term and release rates instead of using plant monitor data

d.

Menu J - Auto Quick dose projection Steam Generator Tube Rupture - this menu uses automatically loaded data to project doses with minimal user intervention or input required.

e.

Menu K-W - Auto Met Back Calculation - uses manually entered offsite monitoring centerline plume dose rate readings to estimate the release source term based on automatically collected meteorological data. This menu option should generally not be used if plant monitors are available.

f.

Menu L - Auto Accum.

Multiple Accident Run - Allows for dose calculations for accidents occurring simultaneously at both units. (See Section 5.14).

NOTE:

If the automatic process identifies missing or bad data MIDAS will prompt the user for manual inputs, even in automatic menu modes.

5.5.13 With 'EOF' selected the following menus are available: Manual

a.

Menu A - Quick dose projection - this menu assumes the release is monitored and prompts the user for input of meteorological and radiological data.

b.

Menu B - Enhanced dose projection - this menu prompts the user for manual input of release point, meteorological data, isotopic mix, and effluent monitor readings.

c.

Menu C -Event Tree - this menu prompts the user for manual input of meteorological data but uses a pull down event tree selection process to determine source term and release rates instead of using plant monitor data.

d.

Menu D - Quick dose projection Steam Generator Tube Rupture -

this menu assumes the release is monitored and prompts the user for input of meteorological and radiological data.

e.

Menu E-W -Back Dose Calculation - uses manually entered offsite monitoring centerline plume dose rate readings and a pull down event tree selection process to determine the isotopic mix to estimate the release source term using manually entered meteorological data. This menu option should generally not be used if plant monitors are available.

5.6.2 Meteorological spreadsheet - includes date and time, wind direction, wind speed, delta T (or stability class), and precipitation

a.

Make certain that the proper met data is being applied when entering data manually because several sets of meteorological data are available from sensors at different levels on the primary tower and from a backup tower.

b.

Because all release points are treated as ground level, the speed and direction values should be from the primary tower 10 meter sensors and the stability should be derived from the 60 - 10 delta T.

5.6.9 Spreadsheet lines highlighted in the time column with RED are the start time of the release.

5.6.10 Spreadsheet lines highlighted in the time column in LIGHT BLUE are the start time of the dose assessment.

5.6.11 Because, for offsite protective action purposes, dose that has already been incurred is not used for protective action decisions, the start of release and start of dose assessment will not be the same except for initial calculations.

a.

application of ground level release point model to station vent will likely cause underestimate of ottsite mixing and overestimate of dose consequences of release

b.

application of ground level release point model tor the condenser oft-gas release is probably the best reasonable model

c.

application of a ground level release to the atmospheric steam relief release may significantly underestimate the ottsite mixing DURING THE FIRST SEVERAL MINUTES of a release and will overestimate ottsite dose consequences. After the steam system is substantially depressurized, the ground level release model is more appropriate

d.

application of the ground level release tor vapor containment building leakage is likely the most appropriate model given uncertainty in flow, height above the ground, and other relevant parameters.

5.8 Times and timing in MIDAS 5.8.1 There are several timing concepts important to successful MIDAS dose projections 5.8.2 Meteorological data

IPEC NON-QUALITY RELATED IP-EP-340 Revision 6 et.., Enler.ny, EMERGENCY PROCEDURE PLAN IMPLEMENTING PROCEDURES REFERENCE USE Page 18 of 84 5.9 Automated Data collection 5.10 5.9.1 Automated collection of data is obtained from the EOFPI, U2PI, and U3PI servers.

5.9.2 Short delays are expected between data collection at the source and the availability of the data in the Pl servers.

5.9.3 MIDAS delays acquisition of data for about 75 seconds to ensure data is updated. IF data collection is delayed longer than 75 seconds or there are errors in the time in the computers, automatic data collection will fail.

5.9.4 Because the data collection into the Pl computers is dependent on the time and timing of multiple Pl servers as well as other plant computers and data loggers (met towers) bad or old data may be collected due to delays in the data transfer path before MIDAS tries to acquire the data.

Event Trees 5.10.1 In some events source term may be developed or enhanced by selection of plant conditions from an 'event tree' 5.10.2 The event tree is based on the event trees in the N RC Response Technical Manual but applies only the default noble gas to iodine mixes of 10000:1 or 100:1 in use at IPEC.

5.10.3 As the name suggests, the event tree is a branching process that asks questions based on previous answers 5.10.4 The event tree may have one or two branches after the initial trunk question as shown in the example in Figure 9 below.

Figure 9 Example: MIDAS Event Tree Menu Selections 5.10.5 Each line is based on a pull-down selection list with the next branch typically dependent on the answer to the previous branch.

5.10.6 There are four accident types, three isotopic mixes, and for steam generator releases, two possible flow rates in event tree. The tree selections are shown in detail in Attachment 9.1

5.10.8 For unmonitored releases, the event tree will derive isotopic release rates (mix and magnitude) 5.10.9 For releases with monitor data, the event tree will determine the isotopic mix which is then applied to the total activity applicable for the monitor reading to determine the magnitude of the release 5.10.1 OThe selection of release point does NOT limit the event tree menu choices. Therefore the user must ensure that the release point and the accident type in the event tree are consistent. E.g. do not select release point 1 and a steam generator tube failure event tree (more appropriate for release point 3).

5.11 MIDAS Main input control page NOTE:

Each time the NEXT arrow is selected, MIDAS will inspect the input parameters to test if there is valid complete data for a successful dose projection and will provide warnings if data is incomplete or invalid. Some of these warnings are informational and some are critical. The warnings messages must be reviewed to determine if they are critical or not.
