Benchmark Description
The present benchmark is designed to provide
the framework to assess the ability of modern reactor kinetic codes to
predict
the transient response of a core partially loaded with MOX fuel. This benchmark employs many of the
characteristics of the NEACRP L-335 PWR benchmark proposed by Finnemann
in 1991
[Finnemann, 1991] which was designed to assess the ability of spatial
kinetics
codes to model rod ejection transients. The
current problem adds the complexity of modelling a rod
eject in a
core fuelled partially with weapons grade MOX. The
core chosen for the simulation is based on four-loop
Westinghouse
PWR power plant similar to the reactor chosen for Plutonium disposition
in the U.S.
The problem is designed
primarily to assess
core simulators, and therefore few group constants are specified at the
level
of homogenized pin cells. However, some
participants may wish to utilize their own cross section generation
methodology
or to model explicitly the heterogeneous pins in their core
simulators. Therefore, the benchmark will also specify
material compositions and pin geometries in order to reach the widest
range of
participants and in order to be applicable to continuing code
developments in
which heterogeneous full core transport transients are becoming
possible.
