Refabrication and reinstrumentation of irradiated LWR fuel rods for irradiation testing at HFR Petten
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.
