“…FRs have been mainly developed as breeder reactors but they act as a burner reactor in the phase-out scenario. The burner reactor has no blanket region for breeding, larger Pu content, and shorter operation-cycle length [1]. The ADS has been designed as an MA transmuter with a smaller amount of Pu but changes to a Pu transmuter in this scenario.…”

Nuclear Back-End and Transmutation Technology for Waste Disposal

With consideration of the phase-out option from nuclear power (NP) utilization in Japan, an accelerator-driven system (ADS) for Pu transmutation has been designed and scenario analysis performed. The ADS is designed based on the existing ADS design for MA transmutation, and the six-batch ADS was selected as a reference design for scenario analysis. In the scenario analysis, the oncethrough scenario of light water reactor (LWR) spent fuel is referred to as a conventional scenario with a LWR-MOX utilization scenario. As the transmutation scenario, three cases of transmuters that are only-FR, only-ADS, and both-FR +ADS are analyzed. The numbers of necessary transmuters are obtained as 15 to 32 units, and the necessary period for transmutation as 180-240 years. The benefit on repository by reduction of Pu and MA is reduction of repository area by a factor of five and of decay time of toxicity by one order of magnitude. The FR+ADS scenario would be a modest solution, although the ADS scenario is preferable if rapid transmutation is required.

“…Such energy resources should meet several requirements, including specifically low environmental burden, economical competitiveness, and efficient use of natural resources. In particular, since global warming mainly caused by carbon dioxide (CO 2 ) accumulation has become a main concern, energy resources that emit no CO 2 or only a small amount of it are strongly expected to be listed at the top among those that satisfy the abovementioned requirements.…”

“…The recycling of MAs also contributes to the effective use of natural resources, since MAs yield new high-performance fissile materials other than Pu nuclides, such as 242m Am and 245 Cm. The FR has intrinsic advantages in MA-loading into the core because of its flexibility for acceptance of neutron absorbers like MAs, together with higher fission to capture ratio than that in thermal reactors Wakabayashi et al [2]. These advantages should make an effective MA transmutation and utilization possible.…”

Research and development of innovative oxide fuels doped with minor actinides for use in fast reactors are underway. Management of minor actinides in a fast reactor fuel cycle is a key technology for successful realization of a sustainable energy supply with a low impact on the environment. Americium-doped oxide fuels are focused on as representative of minor actinides-containing fuel. Two types of fuels were designed and fabrication tests were carried out. Fundamental properties were also investigated. Results can effectively be reflected to establishment of the fast reactor cycle with minor actinides.

“…Recently, fast reactors for burning plutonium, instead of breeding, have been actively studied. [1][2][3][4] For the purpose of burning plutonium, fast reactors using highly enriched plutonium or uranium-free fuel are considered preferable to enhance the fission reaction of plutonium and to reduce the capture reaction of uranium. The feasibility of such strange fuel should be verified from many viewpoints such as burn-up reactivity, irradiation behavior, manufacturing, compatibility with cladding, and treatment of spent fuel.…”

A uranium-free fast reactor was simulated at FCA in order to examine the prediction accuracy for sodium void effect of plutonium burning fast reactors. Material sample worth for plutonium and B 4 C was also measured to compare its prediction accuracy with that for the sodium void reactivity worth. It was found that an axial distribution of plutonium sample worth and the central B 4 C sample worth for various kinds of 10 B enrichment were precisely calculated by the conventional calculation method for fast reactors with 70-group structure. The sodium void reactivity worth was, however, poorly predicted especially for the non-leakage term. This discrepancy seems to be caused by the peculiar energy breakdown of the non-leakage term in the uranium-free fast reactor.
