Abstract
One outcome of the OECD/NEA ISP-47 activity was the
recommendation to elaborate a 'Generic Containment' in
order to allow comparing and rating the results obtained
by different lumped-parameter models on plant scale.
Within the European SARNET2 project
(http://www.sar-net.eu), such a Generic Containment
nodalisation, based on a German PWR (1300MWel), was
defined. This agreement on the nodalisation allows
investigating the remaining differences among the
results, especially the 'user-effect', related to the
modelling choices, as well as fundamental differences in
the underlying model basis in detail. The methodology
applied in order to compare the different code
predictions consisted of a series of three benchmark
steps with increasing complexity as well as a systematic
comparison of characteristic variables and
observations.This paper summarises the benchmark series,
the lessons learned during specifying the steps,
comparing and discussing the results and finally gives an
outlook on future steps
