Machines used:
Package-ID Orig. Computer Test Computer
NEA-0845/01 UNIVAC 1110 UNIVAC 1110
3. DESCRIPTION OF PROBLEM OR FUNCTION -
EDO evaluates individual and collective doses to man from atmospheric releases of noble gases and other gaseous effluents.
4. METHOD OF SOLUTION -
The dose calculations are carried out by following the guide- lines of USNRC Regulatory Guide 1.109.
Radiation exposure for maximum individuals and population are estimated within 30 km from the nuclear plant. This area is divided into 160 circular trapezoids, to which computations are referred.
Four age groups, seven organs for internal dose and two for external dose have been considered.
Dose calculations are done through 14 pathways, 7 for liquid effluents, one for noble gases, and 6 for the rest of gaseous effluents.
5. RESTRICTIONS ON THE COMPLEXITY OF THE PROBLEM -
The following are the maximum dimension sizes preset in the code:
73 radionuclides (other than noble gases)
15 noble gases
160 circular trapezoids
31 chemical elements
4 types of aquatic foods
15 points of exposure for shorelines
15 trapezoids influenced by each point
4 terrestrial food pathways
100 centres of population.
Some of these limits can be varied.
6. TYPICAL RUNNING TIME -
EDO consists of a main program and 8 sub- routines for calculations. Running time for a case which considers all the subroutines, 46 nuclides (liquid effluents), 12 nuclides (gaseous effluents) and 11 noble gases, is about 26 minutes, of which 1 minute 20 seconds are CPU time.
NEA-DB executed the test case included in the package (NEA 0845/01)
on UNIVAC 1110 in 145 seconds of CPU time.
7. UNUSUAL FEATURES OF THE PROGRAM -
8. RELATED AND AUXILIARY PROGRAMS -
META/TRAP can be used to obtain meteorological parameters.
9. STATUS -
NEA-0845/01: 18-OCT-1983 Tested at NEADB

11. MACHINE REQUIREMENTS -
Main storage: 46 kwords on UNIVAC 1100 series computer, when segmentation MAP program is used.
8 blocks on tape or 8 tracks of mass storage for 6 files containing constant data input. Two of these files must be direct access files.
FORTRAN V standard system library functions.
I/O devices: card reader and printer.
12. PROGRAMMING LANGUAGE(S) USED -
NEA-0845/01: FORTRAN-V (UNIVAC)
13. OPERATING SYSTEM UNDER WHICH PROGRAM IS EXECUTED -
EXEC 8 multiprocessor system, level 36R2D (UNIVAC 1100/60)
Ver. 33R3-33.3C93 (UNIVAC 1108).
14. OTHER PROGRAMMING OR OPERATING INFORMATION OR RESTRICTIONS -
Due to memory requirements, the programs are linked using a segmented MAP. Users on other computers than UNIVAC are advised to adhere to the overlay structure, listed in the MAP program.
Also, in order to reduce main storage, dose factor data for ingestion and inhalation are recorded as direct access files.
