Background

The main areas of SCIP III will be treated in three tasks.

In Task 1, LOCA issues, in particular fuel fragmentation, relocation and release. The consequences of cladding overheating and its impact on mechanical cladding properties, due to off normal transients at lower than LOCA typical temperatures and the axial constraint on fuel rod performance during a LOCA transient, are investigated as well.

In task 2, some PCMI and PCI issues are further studied, as the beneficial effect on PCI of slow and staircase ramps compared with fast ramps and oxygen impact on PCI resistance.

In task 3, modelling support to the experiments planning and to the data analysis is given by the participants and will stimulate understanding of the mechanisms important for transient fuel performances.

There will be progress reports issued for all three tasks once a year.
