TRAB is a :Ransient Analysis code for BWRs developed at
the Technical Research Centre of Finland. It models the
phenomena in the interior of the BWR pressure vessel and
in related subsystems. The core model of TRAB can be used
separately for LWR modelling. For PWR modelling the core
model of TRAB is connected to circuit model SMABRE to
form the SMATRA code.
This report is a user's manual and documents the
structure, contents and preparation of input for TRAB.
The structure of TRAB input is very flexible, featuring
input groups and subgroups identified with keywords and
given in any order as well as data items in free format,
freely mixed with explanatory texts. Users interface of
the code can be used for modelling within input: through
normal input it is possible to create new submodels.
These may be functional or tabulated dependencies of the
code variables, different types of delays, or ordinary
linear differential equations (e.g., control systems).
