3. DESCRIPTION OF TEST FACILITY
REBEKA test facility operated at Kernforschungszentrum Karlsruhe Research Center
- 48 rod fuel simulator bundle with cosine shaped power distribution
- internal INCONEL heater rods
- standard Zircaloy-cladding
- pressurized and unpressurized fuel rod simulators
- controlled cooling conditions at the bundle inlet (blowdown, refill and reflood period)

4. DESCRIPTION OF TEST
The test was carried of in March 1983. It consisted in investigating into the non-steady material behaviour of a bundle of electrically heated fuel rod simulators with respect to
- local fuel temperatures,
- cladding strain,
- time to burst and
- local strain at location of burst
Inlet coolant flow conditions and local heat transfer coefficients along the simulator bundle have been provided to participants in "open" post-test exercise to decouple analytical tasks for simulating cooling conditions and local fuel rod material behaviour.
