LWR fuel testing at the High Flux Reactor (HFR) and the Hot Cells at Petten has been performed successfully with pre-irradiated fuel rod segments. The testing methods have been extended with hot cell techniques for: (i) re-fabrication of test fuel rods from full length fuel rods from power reactors; (ii) re-instrumentation of pre-irradiated fuel rod segments with pressure sensors; (iii) instrumentation of re-fabricated fuel rods or fuel rod segments with central thermocouple and/or pressure sensors. After re-fabrication and/or instrumentation the fuel rods are transported to the HFR, where they are remotely loaded into the standard LWR fuel rod testing facilities. These facilities provide a wide range of testing capabilities under typical LWR system conditions (both PWR and BWR) including various types of transient scenarios. Several fuel rods have been re-fabricated and two fuel rod segments have been re-instrumented, and successfully tested at the HFR. Studies and preparations for re-instrumentation of fuel rods with a central thermocouple and/or pressure sensors are in progress.
