INREAD: An interactive program for generating the INTERTRAN-I input data file.
UPEML: A machine-portable CDC UPDATE emulator.
IAEA, Vienna, Austria.
OECD Nuclear Energy Agency Data Bank, Gif-sur-Yvette, Cedex, France.
3. CODING LANGUAGE AND COMPUTER
Fortran V; NAS 9080 (IBM-like), CYBER-740, VAX 11/780.
4. NATURE OF PROBLEM SOLVED
INTERTRAN-I calculates the radiological impact from incident-free transports and vehicular
accidents involving radioactive materials. The code also handles accidents which may occur during
5. METHOD OF SOLUTION
The INTERTRAN-I code deals with several submodels. In the standard shipment model, the
shipments have to be divided into standard shipments. The transportation model can handle ten
different transport situations. The population density model can handle three population density zones.
The incident-free dose calculation calculates doses to crew, passengers, flight attendants, handlers,
population surrounding transport link, population traveling on transport link, population near the
transport vehicle while stopped, and warehouse personnel. The accident categorization model contains
frequencies of occurrence for different accident severities in different environments. The material
dispersibility model takes into consideration the dispersibility difference due to the chemical and
physical properties of the materials shipped. The atmospheric dispersion model calculates the time-integrated concentration at a specific distance from the release. The health effects model analyzes early
fatalities and morbidities, latent cancer fatalities, and genetic effects.
6. RESTRICTIONS OR LIMITATIONS
Three population density zones, 200 different shipments per run, 10 different package types, 80
material types, 10 transport modes, 11 accident severity categories, 30 iso-dose areas, 30 rem levels,
8 organs for dose calculation, 5 early fatality organs, 11 material dispersivity categories, 10 material
7. TYPICAL RUNNING TIME
The sample problems for INTERTRAN-I required CPU times of 0.85s (NAS 9080), 13.79s (CDC
CYBER-740), and 12.84s (VAX 11/780).
8. COMPUTER HARDWARE REQUIREMENTS
INTERTRAN-I requires 284 K bytes on NAS 9080, 140 K octal words on CDC CYBER-740, and
300 K bytes on VAX 11/780.
9. COMPUTER SOFTWARE REQUIREMENTS
A Fortran V compiler is required. Operating systems are NOS (CDC CYBER-740), MVS-XA
(NAS 9080), and VMS (VAX-11/780).
