1. NAME AND TITLE
INVENT: A Radionuclide Inventory and Hazard Index Code.
Associated Nuclear Services, EPSOM, Surrey, UK through NEA Data Bank, France.
3. CODING LANGUAGE AND COMPUTER
Fortran 77, VAX.
4. NATURE OF PROBLEM SOLVED
INVENT is designed to facilitate the post-closure radiological assessment of land-based repositories
for low and intermediate-level waste.
5. METHOD OF SOLUTION
INVENT calculates hazard indices for individual nuclides for both ingestion and inhalation routes,
by multiplying the time-dependent activity by an appropriate value of the committed effective dose
equivalent per unit intake of activity, as given in ICRP Publication 30.
6. RESTRICTIONS OR LIMITATIONS
7. TYPICAL RUNNING TIME
On a VAX 8810, the module INVENT took 1.06 seconds; DFSTOR took 0.45 seconds; GAMMA1
took 0.61 seconds.
8. COMPUTER HARDWARE REQUIREMENTS
INVENT runs on the VAX family of computers.
9. COMPUTER SOFTWARE REQUIREMENTS
A Fortran 77 compiler is required. The operating system for the VAX is VMS.
