Abstract
Criticality safety assessments require sensitivity analyses which can be
quite tedious if preformed manually. In order to reduce manual work and
facilitate sensitivity studies, a calculation package has been set up. The
package is built around MCNP which is used for the criticality calculations.
The package consists of a data transfer and analysis program written in perl,
and a set of skeletal inputs, called here models, for the fuel transport and
storage systems including the fuel assembly. The models contain all the
details for the assembly and the storage system. Some values in the models are
replaced by keywords for the parameter. Values for the keywords are given in
the input of the package and the keywords in the models are replaced by the
appropriate value in the actual inputs for the MCNP runs. The package gives an
easy and time-saving way to make a lot of criticality calculations with only
small modifications to the inputs. Currently the models cover the transport
and storage systems of Loviisa NPP. In principal, the package could be used to
analyze any transport or storage system as long as a model for the specific
system is constructed. In this paper, the usability is demonstrated with two
different storage systems.
