ABSTRACT O
METPAC is designed to provide current site-specific estimates and predictions of dose rates for a nuclear power station immediately following an accidental airborne radioactive release.
The guidelines of NUREG-0654, Criteria for Preparation and Evaluation of Radiological Emergency Response Plans and Preparedness in Support of Nuclear Power Plants, were followed in the program design.
METPAC is a series of computer codes designed to calculate dose rates and grapht'cally displ&y the location and dimensions of the resulting plume.
METPAC handles releases from combinations of any of tne following four pathways:
the primary vent stack, the containment leakage, an unmonitored release, and the steam line valve.
The program calculates off-site whole body, and infant thyroid dose rates and can display whole body and thyroid plume locations.
Protective action recommendations are also determined.
,Tb! hearts of the METPAC program are the dispersion and dose models.
The dispersion model is a Gaussian, cariable trajectory, plume segment
, atmospheric transport and diffusion code designed to handle the site-specific atmospheric dispersion characteristics associated with a nuclear power station site. Plume trajectories are calculated using data from the plant's on-site meteorological tower.
The model can track plume location and magnitude as a function of time, given time-varying meteorological data.
It can also project plume location, magnitude and travel time as a function of distance from the plant assuming steady-state meteorological conditions.
Plume centerline diffusion factors (depleted and finite-cloud gamma) and deposition factors are provided for both continuous and intermittent releases from various release pathways.
The dose model calculates a source term for stack, containment unmonitored and steamline pathways based on a radiological measurement, a flow rate and a function J(t).
The J(t) function correlates the radiological measurement with the concentration in the release pathway for an assumed mixture of radionuclides that form the source term.
This source term is 0

1.0 INTRODUCTION
O V
1.1 Purpose HETPAC is a software package developed to produce dispersion and dose estimates during a radiological emergency.
The purpose of this document is to aid the user in the execution of METPAC.
The METPAC system will operate at any user-specifiea location and has been designed to run on an IBM PC-XT or PC-AT computer, 1.2 Hardware The hardware required to operate METPAC is:
o an IBM PC-XT or PC-AT computer with at least 512 KB of on-line memory and a greater than or equal to 10 MB hard disk.
The METPAC code and files require 7.5 MB of the hard disk.
o monochrome monitor and driver o
color monitor and AMDEK driver card o
Epson FX-100 printer o
8087 floating point processor o
FTG light pen The monochrome and color monitors are both used to display dispersion and dose information - the color monitor displays graphic information while the monochrome monitor displays text information about the incident.
The printer can provide hard copy of both screens.
1.3 Software The software has been designed to run under the PC DOS 3.1 operating system using the IBM Professional FORTRAN Compiler, IBM MACR 0 Assembler, and the HALO Graphics Library.
O 5912R/18.173 d
p The user can execute METPAC by running a batch procedure file.
The U
batch procedure file schedules all of the METPAC programs
'.n their proper order.
The end result is a graphic display of plume position and dose estimates.
1.4 Description HETPAC is a versatile tool for analyzing the consequences of an accidental release of radiation to the atmosphere. The program allows for the analysis of a plume release or a multiple puff release from either a ground (steam line, unmonitored or containment) or elevated (stack) release path for a period of time no greater than 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />.
Multi-level release paths can be analyzed.
The program can be executed in near real-time or in a predictive mode.
Default input in a predictive mode is persistence, but all parameters may be modified given knowledge of expected changes.
The result of the program execution is the calculation of the ga.nma n
(whole body) dose rate, and the infant thyroid dose rate.
These dose rates U
are calculated for specific plume centerline points which are determined by wind speed and direction.
They are also calculated on the straightline direction at site boundary and at every mile out to ten miles. Dose rate information is displayed both on the screen and on the printer.
The printer will also display integrated doses for the straightline direction, and determine protecti'.1 acticn recommendations based on those numbers.
Plume configuration is displayed on the graphics screen.
The plume is plotted over a ten-mile radius site map which can be modified to display additional site features.
A hard copy of the graphics screen can be obtained.
1.5 Limitations Information necessary to execute METPAC must be entered manually.
The system aeeds a minimum 3. mount of information to execute.
These are the date and time of shutdown and start of release, the radiological data for the given pathway, and the meteorological data. Once the detes and times have been entered, they cannot be changed without rerunning the program.
The input of V
meteorological data produces the dispersion estimates (depleted and gamma CHI /Q) and plume location, s 5912R/18.173
. - -. - - - = _.
4 l
To produce a gama dose rate, radiation monitor information and flow i
rate information must be provided.
Thyroid dose rates will be calculated I
using a site-specific noble gas i.o todine conversion factor.
For a more i
refined thyroid estimate, Iodine-131 through Iodine-135 isotopics must be entered. When noble gas information is provided, the program will use those readings to override the radiation monitor readings in the. production of the 1
gamma dose rate.
The newly calculated release rate will change proportionally l
according to further input of radiation monitor readings.
The user is able to manually specify the use of monitor readings for both gamma and thyroid doses, or the use of monitor readings for gamma doses with isotopic input being used forthyrdiddoses,ortheuseofisotopicinputforbothgammaandthyroid i
doses.
The program produces plume segments or puffs in fixed 15-minute advection steps. Up to 29 plume points are tracked and any plume segments that travel beyond 20 miles will not be tracked.
Releases can only terminate j
en the past 1/4-hour boundary.
~
i On continued operation of the program, persistence of most conditions i
are assumed unless the user modifies the input data.
In this way, projections may be made, either by stepping through the time periods one 1/4-hour at a i
time or by use of the batch option for up to 32 1/4-hour periods.

readings do not persist.
i Only one plume type may be displayed at any time.
There is no i

significance to the shading of the plume.
Portions of a plume may not be j
shaded.
Plumes can only be displayed in the ten mile radius around the plant because the background map has not been digitized beyond this distance.

3.1 Theory of Operation i
i
]
METPAC is designed as a tool for assessing the radiological l
consequences of an accident at a nuclear power plant in real time.
Therefore, j
i METPAC assumes the user is running the program as the accident is occurring, 3
The. implication of this assumption is that the program expects input continuously throughout the accident with input incremented over discrete time
]
periods.
The time period chosen for updating input to METPAC is fifteen minutes. This coincides with the averaging period of the meteorological data.
It is suggested that radiological inputs to METPAC be given 'as elther a l
15-minute average value or a 15-minute maximum value.
Because of the continuous operation assumption, if the user starts execution of the program after the start of the release, the user will have to j
start the execution of METPAC at release time and then cycle through 15-minute j
runs until tne user brings the analysis up to real time.
This will require i
that the user have all of the inputs over the elapsed time between the start I
I of release and real time.
A batch option is provided to facilitate this.
[
l What-if scenarios can niso be run in batch while retaining the status f
I of the real-time accident.
The batch option can provide projections for a
)
I future time period, including a predictive containment venting analysis and a predictive containment failure analysis, neither of which is available in real-time mode.

i 3.2 General Flow I
In order to execute METPAC, the user need only type in METPAC, followed I
by (Return).
This starts the execution of a batch procr u e, The batch I
procedure turres off the echo print of all batch commands and de'etes all control files.
It starts the program responsible for accepting user input.
l If the user chooses to quit, the batch procedure will go to exit processing.
If the user chooses to display the last plot, the proccdure will go to plot processing.
If the user chooses to display a printout, the procedure will go to print processing.
If the user chooses to calculate Total Integrated Dose (TID), the procedure will go to TID processing.
If the user chooses to print I
f total integrated dose, the procedure will go to TID print processing.
All other options lead to dose processing.
I i
Under dose processing. the procedure will execute either the ground level dispersion analysis or the elevated level dispersion analysis or both
(~pending on the lesels the user chose to analyze.
The Dispersion Prog am is
[
run twice per level of analysis: once to analyze the current position of the plume, and once to calculate a straightline plume projection.
After the Dispersien Program finishes, the Dose Program starts executing.
This program calculates doses based on the results of the i
Dispersion Program.
After the doses are calculated, the procedure will start print processing, followed by plot processing.
After plot processing, the
{
procedure will loop back to the input processing program.
i Print processing is responsible for producing text printouts of the dispersion and dose results.
It also produces recommendations for protective actions if requested.
If the user chooses to perform only print processing, f
the procedure will loop back to the input processing program.
{
Plot processing first displays text information to the text screen.
~
Then, the program displays the graphics screen.
The program allows the user to print what is displayed on the graphics screen. When the user exits normally from the graphics screen, then the procedure will loop back to the input processing program, u
8-5912R/18.173
Total integrated dose processing is responsible for calculating the J
total integrated dose over the plume path.
After the calculition is performed and the results saved, the procedure returns to the input processing program.
Total integrated dose print processing is responsible for producing text printouts of the results of the total integrated dose calculation.
After the printout is obtained, the procedure returns to the input processing program.
Under exit processing, the procedure will delete some files on disk and print "Program Terminated".
The batch proce. -- %en terminates and the normai operating system prompt appears.
Ex ria; a s not destroy any of the input or output data.

4 The first steo is to turn on the computer, TURN ON:
line printer, and color monitor.
The IBM system will COMPUTER responc by executing a RAM memory test.
The monochrome LINE PRINTER screen will display the number of kilobytes of memory COLOR MONITOR that have checked out.
.g 5912R/18.173
,,d
M.ien the test has checked out 512 KB, the floppy disk drive light will turn on for 1 second, followed by a beep.
Then the floppy disk drive light will turn ou for 4 seconds, followed by the hard disk drive light for 2 secol.Js.
The monochrome screen will then display current ENTER CURRENT DATE system date and will request a new date to be entered.
MH-DD-YY (Return)
Enter the date in format MM-DD-YY (Return) where MM = current month, DD - current day, and YY - the last 2 digits of the current year followed by a return.
The system will specify time and request current time.
The user will respond by typiig the following HH:MM (Return) where HH - current hour on a 24-hour ENTER CURRENT TIME clock (0-23), MM current minutes (0-59).
HH:MM (Return)
The system will respond with C).
The user will now type in METPAC (Return) and the ENTER system will begin executing the METPAC procedure.
METPAC (Return) 4 The first program to execute under METPAC is the input preprocessor to the dispersion and dose calculation programs.
The input preprocessor is a full screen input program.
This means that the user may enter any item in the input list in any order.
The user will do this by moving the cursor to tre desired input location by means of the Cursor Control keys described in Section 2.2.
The user will be presented with the screen shown in Figure 3.1.
This screen describes the current analysis TYPE 1 (Return) situation that HETPAC is executing.
If the user is TYPE Y starting an analysis, a 1 (Return) should be entered.
The program.will verify that the user wishes to choose this option. A "Y" should be typed.

Also note that the "Y" will not appear.
If the user decides to not start a new accident, he should type "N".
i Note th:t the "N" will not appear and that a cursor control key must be user to reposition the cursor on the list of choices.
The next screen that will be presented is shown in Figure:3.2.
The user will move the cursor to the
~
desired location and type the appropriate value for the specific input.
When the user has finishe' with ENTER DATES AND d
the input screen, the user should move the cursor to TIMES the "NEXT SCREEN" position and depress the Return key.

No error checkir,g is done until after the user indicates he is done with the input screen.
If there are scrors with the input, the terminal will beep, a message will appear above the input screen and the cursor will automatically move to the input location that is in error.
The correct values must be input, p

be the same as before.
When all data values have been entered, position the cursor to "RUN" and depress (Return).
Before the "RUN" option is chosen in input LINE PRINTER HUST Screen 4, the user must make sure the line p'rinter is BE ON-LINE NOW on-line and set up for printing. At this time, the color monitor must be on.
After the "RUN" option is chosen, METPAC will error check Screens 3 and 4, then execute.the dispersion and dose programs.
When these programs are complete, a hard copy DISPERSION AND of the dispersion and dose estimates will be printed DOSE ESTIMATES on the line printer (Figures 3.9 and 3.10).
Then the PRINTED pertinent information concerning the accident will be printed on the monochrome screen (Figure 3.11) and
~
the color monitor will activate and clear whatever was previously on the screen.
Next, the background map and Function key menu will appear on the screen
.(Figure 3.12).
The user will specify by use of the Function key menu the design of the display to his choosing.
The Function keys allow the user to do the following:
F1 - draw or take off 5 and 10 mile radius circles SELECT FUNCTION and 16 cardinal direction sectors.
KEY FOR SPECIFIC DESIGN F2 - Draw or take off evacuation roads.
F3 - Draw or take off points of interest.
F4 - Draw or take off town names.
O 5912R/18.173 a;
l F5 - Zooms in on specified area of the map.
g
()
The program will request the user to depress the upper left corner of the zoom box with the light pen.
The user should dete.rmine the desired viewing area and depress the light pen on the upper left corner of this viewing area.
If the user doe 6 not wish to execute this option, depress the light pen
-on the word "EXIT" to the right of the screen. Once the left corner has been chosen, the program will request that the user choose the lower right corner of the viewing area. Upon choosing the lower right corner of the viewing area, the program will draw a box outlining the viewing area to be enlarged.
The user may then continue to modify the lower right corner of the viewing area until the box reflects the desired area to be enlarged. Once the box is suitable, the user must depress the light pen to the word "ACCEPT" and the program will start to draw the new map.
If the box is unsuitable, the user must depress the light pen to the word "REJECT".
The program will then ask for the new upper left corner of the box.
The user can now start a new box or exit.
F6 - Redraws the map.
This option allows the user y
to go back to the original map dimensions after a zoom.
This also allows the user to view plumes of different types and elevations.
F8 - lJses the light pen to retrieve doses.
The program will request that the user depress the light pen to the desired location.
When the U!sr is finished, depress the light pen on the word "EXIT" to the right of the screen.

FIGURE 4.1.7 OV Lesson 1 - Plume Projection Output
- 5912R/18.173
3 4
4.2 Lesson 2 Learning Objectives 1.
Use the edit capabilities of METPAC to correct the 0915 projected plume location using actual meteorological data.
2.
Describe how "instantaneous" radiological data is used with averaged meteorological data.
Scenario j
It is now 0916.
The met data from the period 0900 to 0915 is now 0
available.
The wind direction (upper and lower) was from 0.
This is the only parameter that changed from the previous 15-minute interval.
Show the EOF coordinator where the plume actually went during the 4
period 0905 to 0915.
The stack read',ng is as shown in Figure 4.2.1.
gV l
j Lesson 1.
Note that on Screen 2, the analysis has proceeded to the next time interval--0930.
Using the cursor, the end time of analysis should be changed to 0915.
i 2.
Proceeding to screen four, only the wind direction is changed in I
accordance with the 0915 met data.
~
I 3.
Hove to RUN and press (Return).
This produces the off-site doses and a new map which shows where the plume actually went from 0905 to 0915.
Note that the plume is moving in a different direction.
This is the opposite direction from our initial projection using 0900 meteorology and the assumption of persistence.
It may be good pcactice to consider holding an off-site team in reserve to chase the plume in an opposite direction.
, 5912R/18.173
4.
It is now 0920 and the reported stack monitor reading is as shown in figure 4.2.1.
The EOF coordinator is requesting a new projection before the 0930 met data is available.
(It is good practice to make these projections whether asked or not.)
5.
Assume persistence of met conditions as shown in Figure 4.2.1 at the stack to make the projection.
The average of the stack monitor readings or the highest reading can be used.
Just be consistent in whatever method is chosen.
The result in where the plume is projected to be at 0930.
6.
Note that the meteorological data is sc.eraged over a 15-minute interval.
Radiological data (e.g., the stack monitor) is usually available instantaneously.
It is net logical to use instantaneous l
radiologicel data with a program that averages met data!
Be consistent in your decisions as to how multiple radiological data points are utilized.
The radiological data can not be changed during the 15-minute interval.
Summary t
In this lesson the edit capabilities of METPAC were used to eliminate the projection generated in Lesson 1.
The actual meteorological data were l
used when they became available to show where the plume actually went--not where it was projected to 90.
It should be kept in mind that radiological data is available almost f
instantaneously from the various monitors.
However, meteorological data is avera'ged over 15-minute intervals.
Therefore, judgement must be used when selecting radiological data for use by HETPAC.
The use of the highest rad monitor reading during a 15-minute interval is probably too conservative. An average of the rad monitor readings or the reading that persisted the longest
~
over the 15-minute interval is more appropriate.

1.
Update projections using Option 4 and the program's editing capabilities to produce a "real-time picture" of the plume.

)
Scenario
{
It is 0931.
State officials have already been provided with dose l
l projections for 0930 and 0945.
The stack continues to read as shown in Figure 4.4.1.
The 0930 met data indicates a change in wind speed and wind direction as noted below:
Upper 6 mph 40 deg Lower 3 mph 40 deg t-l Show the officials where the plume was at 0930.
Lesson 1
1 1.
The displayed current analysis time shown on Screen 1 is 0945.
The j
0945 and 0930 projections must be eliminated before continuing the i
real-time analysis, t
2.
Use Option 4 (Eliminate Last 1/4 Hour of Accident) to eliminate the 0945 projection.
Enter "4" followed by a (Return) and note that the end time of analysis changes from 0945 to 0930.
I j
3.
The 0945 projection has been eliminated.
Do not use Option 4 again l
to eliminate the 0930 projection.
Use Option 2 and change the time l
on Screen 2 from 0945'to 0930 (as was done in Lesson 2).
l 1
l 1
4.
Enter the new met data and execute "RUN."

5912R/18.173 t
i - -
5.
Note that if Option 4 (Eliminate Last 1/4 Hour of Accident) had i
been used instead of Option 2 (Continue Accident) the stack monitor reading and the wind direction would have required editing as well as the wind speeds.
Use of Option 2 saved three additional input steps.
6.
Your map should resemble the one attached to the lesson.
Summary The use of Option 4 (Eliminate Last 1/4 Hour of Accident) was illustrated in this lesson. Use Option 4 when more than one projection has been made and current met data becomes available. Option 2 and the edit mode should be used to change the first projection time of analysis to that of the latest met data.
This procedure minimizes the amount of new data that must be input (since the met data is not likely to change by much, if at all).

4.5 Lesson 5 V
Learning Objectives 1.
Use average or maximum radiation levels for input to the program.
2.
Produce projections with new met and rad data by using Batch Option 2, "Project Using Current Analysis With User Input Het and Rad Data."
3.
Use field team readings to produce a corrected doce.
Scenario It is 0935 and the stack monitor is as shown in Figure 4.5.1.
The 0931 stack reading and field team reading is also shown in Fi~gure 4.5.1.
A new projection for 0945 is required.
Lesson 1.
This lesson re-emphasizes the fact that meteorologit31 data is averaged over 15-minute intervals.
Radiological data is available continuously.
2.
Select Batch Execution by typing 7 (Return), then select user input met and rad data by pressing 2 (Return).
3.
Since the new projection is needed for 0945 only, specify 1 quarter-hour by pressing 1 (Return).
Screens 3 and 4 will now appear as before.
4 Use the stack and field team readings as shown in Figure 4.5.1 (or use an average) and make a projection for 0945.
9
'd 5913R/18.174
5.
Use the 0930 met data (it's all you have!) and assume persistence.
6.
Save the data base so that the projection is available in real-time j
mode.
Summary This lesson crphasizes again the fact that met data is averaged over 15-minute intervals.
Radiological data is available instantaneously and therefore must be averaged by the METPAC operator.
Projections with different mot and rad ata can be made by using Batch Option 2.
Note that projections of up to 3;,uarter-hours can be made at a time.
Field team readings can be entered at any time to produce corrected dose readings.

4.1 Lesson 1
% /
Learning Objectives 1.
Input required date to METPAC.
2.
Use best available (current) meteorological date to make initial projections of off-site dose rates.
Scenarlo There has been an incident at the plant.
The reactor was shutdown at 0900. At 0905 the stack was reported to be reading as shown in Figure 4.1.1.
You have arrived at the HETPAC terminal at 0907 and have been requested to determine the off-site dose rates.
Figure 4.1.1 contains all available meteorological and radiological data as of the indicated times.
{J}
Time is now 0907.
Tell the EOF coordinator the off-site doses!
L Lesson 1.
The following lesson should generate the same screens and output as those attached to this lesson plan.
2.
Type in:
METPAC (return) 3.
Select "START NEH ACCIDENT" by typing:
1 (return) then: Y 4.
Enter the relevant dates by typing:
Month,+, Day,+, Year,+,9,+,0,+,+,+,+, Month,+, Day,+, Year,+,9,+,5,+,+,
(Return) 5, Note: On the second screen, only the date and time of the stack
(~)
release are entered since we are assuming this is the only V
pathway.
Select next screen by moving the cursor via the cursor pad to the words "NEXT SCREEN" and pressing (Return). 5912R/lS.173
~.
6.
Enter the radiological data.
When finished, move the cursor using d
the cursor pad, to the words "HET SCREEN" and press (Return).
7.
Note:
The third screen requires information on stack dose rate,
~
etc.
8.
Enter the meteorological data.
When finished, move the cursor, using the cursor pad, to the word "RUN" and press (Return).
-9.
Note:
The fourth screen requires information or, wind soeed, direction, etc.
- 10. The pertinent off-site dose rate information is produced along with a map of the plume. Note that these are projected results of where the plume will be at 0915 based on the best meteorological data aval'lablel 1.e., the data from 0900.
The real time anal'ysis must be performed with the 0915 net data which is not a/ailable yet.
f)
- 11. Note that the length of the plume segment corresponds to the length of a ten-minute release.
- 12. Exercise map options (F1) through (F6) at this time.
- 13. Type:
(F10)
- 14. The procedure to follow when new met data becomes available is demonstrated in the next lesson.
Summary This lesson demonstrated what data is needed to run METPAC.
Since meteorological data is averaged over a 15-minute period, you must wait until the end of each quarter-hour for current meteorological parameters.
- However, one can assume persistence of met conditions and make a projection at any time using the appropriate radiological data and the last quarter-hour met conditions.

4.6 Lesson 6 C
Learning Objectives Use stack air sample isotopic results (when available) to project doses.
Scenario It is 0940 (real time) and you have just been informed that stack range effluent sampler has been changed and analyzed.
The concentration as shown in Figure 6.4.1 for the period 0905 through 0914.
Lesson i
1.
On the first input screen, enter "2" and (Return).
Note that on Screen 2, the time of analysis has advanced to 1000.
Change it to 0915 and type (Return).
O 2.
Move cursor to "Isotopics":
Type Y and enter (Return).
3.
Enter the I-131 concentration at the proper location on the screen; then position cursor to "EXIT" and type (Return).
4.
The program returns to the rad data input screen.
Position cursor to "MET SCREEN" and press (Return) two times. Change the monitor versus isotopic flag to 1.
Position the cursor to "HET SCREEN" and press (Return) two times. Change the monitor versus isotopic flag to 1.
Position the cursor to "MET SCREEN" and press (Return) two times.
5.
The use of the isotopic inp0t results in assigning a release rate for all time periods after 0905.
The program will use this isotopic input in all subsequent projections and analyses.
6.
A 0945 analysis has been produced which includes updated doses O'
based on the isotopic analysis for time periods after 0905.
i1
- 5913R/18.174 l
7.
Note that all periods between 0915 and 0945 have been reanalyzed to O
show the new thyroid dose information.
Summary This exercise demonstrated the option to input isotopic air sample results, when available, to project thyroid doses. When the isotopic input option is used, the program assigns the release rate for all time periods afte( the sample is taken.
If only iodine information is provided, then the thyroid release rate is based on those isotopics and the gamma release rate remains unchanged (based on monitor readings).
If noble gas isotopics are entered, then the gamma release rate will be derived from those isotopics and the monitor readings will be used only to proportion the release rate in the folicwing time periods. At any time, the user may select which calculational method is used.
Note that when subsequent quarter-hours are displayed for editing immediately after isotopes have been entered, the monitor versus isotopic flag O
is set to 0.
The user must change this flag to 1 or 2 for the analysis to use the measured isotopic mixture.
Failure to do so means the calculation will revert to the default isotopic mixtures for those quarter-hours whose monitor versus isotopic flags have not changed.

1.
Continue the analysis by replacing the latest projection with a real time result.
2.
Correct earlier data which was,four3d to be in error.
Scenario l
At 0945 the stack monitor is reported to be as shown in Figure 4.7.1.
The wind speed and direction are as follows:
4 Lower 4 mph Upper 7 mph It is 0946 and the EOF coordinator wants the necessary projJctions and analyses.

At 0950 you are advised that the 0915 met data was incorrect.
Wind 0
direction at that time was from 20 (upper and lower), not 0.
The state i
t representatives want corrected doses, a
Lesson i
i 1.
Provide a real-time aaalysis for 0945.
Enter 2, (Return).
2.
Change time of analysis to 0945 on second screen to eliminate the 4
0945 projection.
3.
Change the wind speed and direction and run the program.
4.
The 0945 analysis has been eliminated and replaced with a real-time 0945 analysis.

5.' Assume persistence of met conditions and create a new 1000 projection with the latest radiological data.
6.
Correct the met ~ data for 0915 (exit by pushing (FIO), and then select "Continue Accident" on the first screen).
7.
On Screen 2, change the time of analysis from 1015 to 0915 and make the corrections to the met data and enter "RUN".
8.
Note that each data entry screen (0930, 0945, 1000) is displayed in sequence to allow you ta make any other necessary corrections.
9.
The computer prints out a corrected set of off-site doses for the i
last quarter-hour interval as well as an updated map.
- 10. Exit by pushing the (F10) key.

Summary O
i In this lesson the 9: 45 analysis was deleted by continuing the accident and changing the time of analysis back to 0945.
The new met data was entered 1
on Screen 4.
The 0945 projection was deleted and replacid with a real-time result. A new 1000 projection was made assuming persistence of the 0945 met conditions.
The scenario then proposed that after the new 1000 projection was made, you were informed that the met data for 0915 was incorrect.
The 0915 met data i
was corrected by continuing tha accident (time of analysis 1015) and edit.ing the second screen back to 0915.
The corrected met data was then entered on the fourth screen.
After exiting, each subsequent data entry screen was displayed in sequence to allow other corrections to be made.
The computer printed a i
corrected set of off-site doses and a corrected plume plot.

4.8 Lesson 8 Learning Objectives 1.
Use the light pen to retrieve doses from each plume segment at a given plume point when the plume blows back on itself.
2.
Review the procedure for summing dose when there are ground level releases (e.g. steam line, unmonitored, or containment leak) as well as a stack release.
Scenario At 1002 you are informed that the stack is as shown in Figure 4.8.1.
The 1000 met data shows the upper and lower winds are now coming from 240.
Lesson ba 1.
Select the Eliminate Last 1/4 Hour option to eliminate the 1000 projection.
2.
Change the stack monitor reading as shown in Figure 4.8.1 (the 0945 reading).
0 3.
Charige the wind directions to 240.
4.
Note that the map shows the plume has blown back on itself.
Doses must be retrieved at the given plume point via the light pen.
5.
See location "X" on plume plot.
Press F8, Light Pen.
Press the light pen to the corresponding portion of the screen and note the dose reported.

s Learning Objectives Terminate the release and track the detached plume.
Scenario 1
The TSC reports to the EOF that the release from the plant terminated at 1010.
The 1015 met data shows the winds have shifted around again to 0
60. At 1030 there has been no change in the met data (i.e., 1015 still applies).
Track the plume.
Lesson 1.
Produce a 1015 plot of the plume.
Since there is a segment being emitted from 1000 to 1010, the release should not be terminated at this time.
O.
2.
The release is assumed to terminate just after 1015.
l 3.
Use the continue accident option to produce a 1030 analysis.
Go to the met screen, i
t 4.
Set the cursor on stack release status and change the "1" to a "0" to indicate the termination of the release.
5.
Note:
The stack monitor reading does not have to be set to zero.
l 6.
The map now shows a detached plume.
The program will display the
]
plume location out to the 10-mile radius from the plant. However, calculations will continue to be performed out to 20 miles.

Summary Termination of the release was demonstrated in this lesson.
In the scenario the release did not stop until 1010.
Therefore, radioactive' material was emitted for 10 minutes in the 1000-1015 met data interval. 3_ir.ce the plume was still dispersing, the release was not' terminated in METP4C'until. t'he.
10i5-1030 interval, when the detached plume was followed.
However, if the release had been terminated at 1001 for example, it
~
~
might have been appropriate to terminate the release in the 1000-1015 interval. Ageneralrulecannotbegivenasthereare-manyj'ariabies5For example, a stack monitor reading of a few R/hr for higher!) may'be'too significant to terminate in the 1000-1015 interval eyen if the release terminated at 1001.
ThejudgementoftheMETPACoper2tormustbereliedupon in these situations.
The plume plots in this lessco show tha detached plume as it is tracked
()
over the countryside'.
The METPAC program will dispiay the plume out to the 10-mile radius.
The program will continue to calculite dose rates out to 20 miles.

4.10 Lesson 10 Learning Objectives c
1.
Begin analysis when the release has been proceeding for an hour prior to your arrival at the EOF.
2.
Use METPAC to analyze a ground level and elevated (stack) release.
3.
Use the Batch Option 3, "Project Using New Data," to quickly bring HETPAC up to date.
4.
Produce the total integrated dose report.
Scenario This is a new accident condition.
The reactor shutdown at 0800.
At 0905 a stack release began as indicated by data in Figure 4.10.1.
At 0920, a radioactive release of undatermined origin was detected at the site boundary.
The site boundary dose rate and the stack monitor readings are as shown in Figure 4.10.1.
A total integrated dose report for 0945 has been requested.
You activate the HETPAC computer at 1000.
Begin your analysis.
There has been no change in plant status since 0920.
t lesson 1.
Gather all met and rad data from 0905 and later.
2.
Select Batch Execution and then specify 3 - project using new data.
3.
Give the computer 0905 as the start of the stack release and 0920 as the start of the unmonitored release.

4.
Specify 3 quarter-hours to project (9:15, 9:30, and 9:45).
5.
Enter met and rad data for each 15-minute period as each screen is presented.
6.
Note that a map of the ground level release has been produced, separate from the stack (elevated) release.
7.
To see the map of the elevated release at 0945, type F6 (redraw).
8.
Press "2" (elevated gamma) then (Return) i n response to the prompt "enter type of plume."
9.
Note that this plume map shows three segments--one for 0905-0915, another for 0916-0930, and a final one for 0931-0945.
- 10. Dose rates from the elevated and ground level releases must be added (at the same plume location) to arrive at the total dose rate (gamma).
- 11. Remember to save the batch execution.
- 12. The first step in producing a total integrated dose report is to calculate the total integrated dose by depressing 8 (Return).
- 13. The selection of 9 (Return), then entry of 0945 (Return) will result in the total integrated dose report for 0945 being printed.
The first section is a total for the entire accident, and the second section contains the current quarter-hour's doses.
- 14. Time of analysis is now 1000 and you are ready to enter current data as it is received at the EOF.

~ Summary This lesson demonstrated the METPAC program's capability to track both elevated and ground level releases.
It also demonstrates how to operate METPAC in batch mode well after a release has occurred.
Each of the plume maps is viewed separately by using the redraw function (F6) on the color monitor. Total dose rate at a given location is determined by summing the dose rates due to the elevated and ground level releases.
The total integrated dose report was also produced.
This report shows the summed doses for both ground and elevated at predetermined distances from the plant.

4.11 Lesson 11 Learning Objectives 1.
To perform a containment venting what if analysis.
This will determine the length and strength of such a release.
Scenario Oue to existing conditions, the pressure in the containment has been rising and is now above the design basis leakage, as shown in Figure 4.11.1.
Without destroying your current METPAC accident, you have been asked to predict the duration of a venting release and the accomoanying dosages.
The time of shutdown and the current met conditions are also shown in Figure 4.11.1.
Lesson 1.
Since a containment venting analysis can only be performed in batch mode, press 7 (Return).
Run Batch Option 3.
2.
Enter time of shutdown and the time of proposed containment venting release.
3.
Enter 1 quarter-hour.
When performing a containment venting analysis, the duration is determined by the computer. One quarter-hour is the entry for this analysis.
4.
Enter the rad and met data.
Be sure to enter "Y" for "STACK VENTING."
5.
Note that the plume is as seen before, but the printout is slightly different.
The printout has been tailored to the duration of the venting.

6.
Do not save the batch execution.
The previously existing HETPAC N/
accident will be needed.
Summary This lesson demonstrated METPAC's ability to produce the resultant doses from an anticipated containment venting release without destroying the I
current METPAC state.
This aspect of METPAC can be useful in other situations, such as "what-if the monitor reading was..." and "what-if the met conditions changed to...".

5.0 PROBLEMS 5.1 File Protection FORTRAN programs are protected from editing.
The only problem that can occur is if one of the METPAC files is purged from the system.
To help reduce this possibility, all METPAC files will be placed in a DOS subdirectory.
There is no absolute protection from having these files deleted; therefore, the only resolution to the problem is to maintain plenty of backup. With the backup diskettes and the following procedure, one would be able to restore METPAC to its original state.
The procedure to reload METPAC is as follows:
Turn on system.
After entry of date and time, load the METPAC Reload Disk i into Drive A.
Type A: RELOAD.
Follow any further instructions as specified on the screen (usually for loading other disks).
This procedure should return METPAC to its original st,6te.
Any 11alysis previously performed will be lost.
5.2 Operation If (CTRL) (yc
- 1) key depressed by accident and the screen r
displays "abort batch procedure", type N.
If the computer is turned off during HETPAC execution, attempt to restart the computer.
If the eighth input screen appears, do not save the batch execution. Depending on the state of HETPAC when the machine was turned off, the' previous accident datt may be lost.
It is safest to eliminate the last quarter-hour and perform that analysis again.
N 5913R/tt.174
~
9,-
y,<
If a p/ inter off-line error or out of paper error occurs during METPAC erecution. rh the printer and type R (for retry).
If the printer is not working, type A.
If the user is in the input program and the cursor control keys fall to work, depress the (Numlock) key once and try again.
If the usu shuts off the computer or loses power during the execution of the dispersion or dose model, data loss will result. Use Option 4 of Screen 1 to eliminate all the quarter hours that were being analyzed.
When in prompt mode, certain prompt messages read "T0" when what is meant is "CR",
For example, the release condition is either 0 or 1.
- Also, prompt m1e will always go through both Screens 3 and 4, regardless of data being previously entered.
If a wind speed of 100 mph or mere is entered, the printout and the graphics screen will read """ HPH".
Review the PAG printout carefully as there is no blank line to aid in the separation of "Evacuate" towns from "Shelter" towns.
Round off of values in prompt and error messages can occur.
For instance, a maximum value of 99.9 will appear in the message as IE2, and the value IE2 will be rejected.
These round-off errors occur because of space limitations.
Once isotopic valuts have been entered for the unmonitored pathway, the only way to not persist those values, without entering new values, is to enter a dose rate of 0.
When viewing multiple quarter-hours of data, the best practice is to return all the way back to Screen 1.
In some cases, a quarter-hour cannot be viewed unless this is done.
