Abstract
This manual describes the technical bases and use of the computer code FIRIN. This code was developed to estimate the source term release of smoke and radioactive particles from potential fires in nuclear fuel cycle facilities. FIRIN is a product of a broader study, Fuel Cycle Accident Analysis, which Pacific Northwest Laboratory conducted for the U.S. Nuclear Regulatory Commission.
The technical bases of FIRIN consist of a nonradioactive fire source term model, compartment effects modeling, and radioactive source term models. These three elements interact with each other in the code affecting the course of the fire.
This report also serves as a complete FIRIN user's manual. Included are
the FIRIN code description with methods/algorithms of calculation and subroutines,
code operating instructions with input requirements, and output descriptions.
