“…Seventy GWe in 2010 is consistent with the value shown by the Electricity Industry Council's report for Japan given in July 1998. Above nuclear power capacity well coincides with that supposed in the paper (Hamamoto et al, 2001) which discussed the MOX cores for effective use of Pu in LWRs. The following installation projection of a large FBR is assumed.…”

“…The experiments of these programs were dedicated to an advanced LWR MOX core concept that is characterized by high-moderation full-MOX LWR cores. 2,10) The MISTRAL program includes one homogeneous UO 2 core, two full-MOX homogeneous cores, and one PWRmockup full-MOX core, which have moderation ratios of 5 to 6 in terms of hydrogen-to-heavy-metal atomic ratio (H/ HM). The BASALA program includes two BWR-mockup full-MOX cores, which have moderation ratios of 4 to 9 in H/HM.…”

A core physics experimental program FUBILA has been performed to study core physics characteristics of full-MOX BWR cores consisting of high Pu-enriched MOX assemblies for high burnups. The program includes the measurement of reactivity worth, which is essential in operating BWR cores. The reactivity worth is due to the reactivity caused by (1) changes in the in-channel void fraction of assemblies, (2) the insertion of a B 4 C control blade, (3) Gd 2 O 3 -UO 2 rods and UO 2 rods in assemblies, and (4) the mixing of boron in a moderator related to a stand-by liquid control system. The reactivity worth was measured by the modified neutron source multiplication method using the reactivity worth of a pilot rod as a reference worth. The measured reactivity worth was determined by processing count rates of neutron detectors taking into account the detector efficiency and effective neutron source intensity analyzed by three-dimensional transport calculations. Comparing the measured reactivity worth with the results obtained by deterministic calculation methods and a Monte Carlo calculation method, the accuracy of the calculations was evaluated. The calculated results generally well reproduce the measurements, except for the boron reactivity worth in the moderator, for which the calculations overestimate the reactivity worth.
