ABSTRACT
As a nuclear reactor relies entirely on fluid circuits
for energy transfer and transport, modelling
thermalhydraulic behaviour plays a pivotal role in
reactor design and development, and methods of
improving the accuracy and efficiency of
thermalhydraulic computations are sought continually.
The presentation describes a rational approach to
successful development and application of
thermalhydraulic computer codes. The basic two-fluid
conservation equations are introduced, and various
models of two-phase flow are also mentioned together
with the auxiliary constitutive relationships required
for closure of the equation set.
Codes are grouped broadly into two classifications,
system codes and component codes. The former attempt
to model all components in a reactor circuit including
associated thermalhydraulic communicating structures,
and, because of this diversity, are usually restricted
to one dimension. The latter attempt to model
particular components in a more detailed manner and are
usually multi-dimensional.
The talk will dwell primarily on specialized and
component codes and present sample applications and
conclude with a look at some of the current concerns
and uncertainties in development of such codes.
