To measure the integrated response of UO2 and its cladding to conditions associated with PCI, the Japan Atomic Energy Research Institute carried out a series of experiments in the Halden BWR. The experiment involved two major objectives. The first was to study the influence of rod design parameters on PCI. Diametral gap, wall cladding thickness, SiO2 additive, and pellet grain size were used as design parameters. The second objective was to study the influence of preirradiation (i.e. burnup) on PCI. The maximum burnup attained in the experiment was 23 MWd/kgU. These research results can be applied to current BWR-type fuel rods.
The tests were performed between April 1977 and March 1981.
Keywords: boiling water reactor, pellet clad interaction (pci).
