Description

The computer code RIBD/IRT is a modified version of RIBD-II. It is a grid processor that calculates isotopic concentrations resulting from two fission sources with normal down-chain decay by beta emission and isomeric transfers and inter-chain coupling resulting from n-gamma reactions. Calculations can be made to follow an irradiation history through an unlimited number of step changes of unrestricted duration and variability including shutdown periods, restarts at different power levels and/or any other level changes. Output information includes time-dependent inventories, activities, decay powers, and energy releases for as many as 800 fission products. Modifications to RIBD-II were necessitated by Loss-of-Coolant Accident (LOCA) studies conducted by IRT Corporation regarding fission product source term definition. This manual describes the modifications to RIBD-II, input requirements and a sample problem. The appendices give a listing of RIBD/IRT, sample output, and a listing of a code called ZIP which prepares the library tape for input to RIBD/IRT
