In 1996, a new project for the investigation of passive safety injection systems of ALWR’s begun. The new project, entitled "Investigation of Passive Safety Injection Systems of Advanced Light Water Reactors", is a part of the INNO cluster of the European Commission Nuclear Fission Safety (NFS-2) Programme. The project received funding from the European Commission. The general objectives of the new project are:

• to provide new and independent information about passive safety injection system performance,

• to contribute to a public data base for the users and developers of thermal-hydraulic computer codes on the phenomenological behaviour of PSIS’s in LOCA conditions, and

• to identify the accuracy, uncertainties and limitations of thermal-hydraulic computer codes in the modelling of passive safety injection system behaviour.
