Abstract
VTT Energy, in co-operation with Lappeenranta University
of Technology, has run experiments in the PACTEL
thermal-hydraulic test loop to study the performance of
Passive Safety Injection Systems (PSISs) during
loss-of-coolant accidents in Advanced Light Water
Reactors (ALWRs) being designed for commercial use within
the next 3-10 years. The experiments were a part of the
European Commission's Nuclear Fission Safety programme.
The main objectives of the project were to provide new
and independent experiment data on the PSISs used in
ALWRs, to create a data base for users and developers of
thermal-hydraulic computer codes on the behaviour of
PSISs, and to identify the accuracy, uncertainties and
limitations of existing thermal-hydraulic codes in the
modelling of PSISs. The PACTEL experiments served the
first two objectives. The computer code simulations of
selected experiments, still under way, will serve the
third objective.
