Benchmarking of economic evaluation models for an advanced loop-type sodium cooled fast reactor

Mukaida, Kyoko; Kato, Atsushi; Shiotani, Hiroki; Hayafune, Hiroki; Ono, Kiyoshi

Nuclear Engineering and Design, 324, p.35 - 44, 2017/12

 Times Cited Count:2 Percentile:28.88(Nuclear Science & Technology)

An economic calculation model based on detailed mass-flow (the JAEA model) was developed for the comprehensive evaluation of an advanced loop-type sodium-cooled fast reactor cycle system (SFR) designed in the FaCT project. The JAEA model enables calculation of the processing amount and its composition in each facility by simulating mass-flow, and has function to evaluate economics based on the processing amount. In this report, to identify the difference in evaluation methods between the JAEA model and an internationally-authorized code, and verify its calculation functions, the generation cost of SFR system was evaluated using the JAEA model and the G4-ECONS. Consequently, it was clarified that the JAEA model is influenced to higher degree by the discount rate. When the present value was not taken into account, the results of both methods were quite similar, but it was found that the sensitivity of the load factor is relatively larger the G4-ECONS than in the JAEA model.

Ono, Kiyoshi; Shiotani, Hiroki; Ohtaki, Akira; Mukaida, Kyoko; Abe, Tomoyuki

Proceedings of International Conference on Fast Reactors and Related Fuel Cycles; Safe Technologies and Sustainable Scenarios (FR-13) (USB Flash Drive), 10 Pages, 2013/03

In parallel to the mid-term analyses by the AEC after the Fukushima-accident, JAEA implemented the long-term scenario analyses for the nuclear fuel cycle options including FR cycle deployment. As a result, it was revealed that FR cycle deployment brings great benefits to reduction of uranium demand, spent fuel storage, radioactive waste generation, and Pu stockpiles in addition to potential hazard of HLW in "20 GWe constant after 2030" case. Meanwhile, it was also revealed the benefits of reduction of radioactive waste generation and Pu stockpiles in "Gradual decrease from 20 GWe after 2030" case.

Storage and disposal of high-level radioactive waste from advanced FBR fuel cycle

Nishihara, Kenji; Oigawa, Hiroyuki; Nakayama, Shinichi; Ono, Kiyoshi; Shiotani, Hiroki

Proceedings of International Conference on Toward and Over the Fukushima Daiichi Accident (GLOBAL 2011) (CD-ROM), 7 Pages, 2011/12

Waste management of the fast breeder reactor (FBR) fuel cycle with and without partitioning and transmutation (P&T) was investigated by focusing thermal constraints in storage and disposal facilities. The result showed that transmutation of minor actinides (MAs) is essentially effective to reduce the waste emplacement area in repository, and a combination of P&T can provide a compact disposal with a smaller emplacement area than the conventional repository design by two orders of magnitude. Cost analysis revealed that the cost for storage and disposal is comparable among the conventional light water reactor, FBR without P&T, and FBR only with MA-transmutation. The cost of disposal for FBR fuel cycle with P&T is significantly reduced by an order of magnitude from the others, while that of storage does not increase.

Introduction to nuclear supply chain management; In the context of fuel cycle strategy from LWR cycle system to FR cycle system

Shiotani, Hiroki; Ono, Kiyoshi; Yasumatsu, Naoto*; Heta, Masanori*; Namba, Takashi

Proceedings of International Conference on Toward and Over the Fukushima Daiichi Accident (GLOBAL 2011) (CD-ROM), 9 Pages, 2011/12

In this paper, the terminologies and ideas of SCM was introduced into the scenario study to give a fresh perspective for considering LWR cycle to FR cycle transition strategies in Japan. Then, an analytical tool (SCM tool) which has been developed by the authors is used to survey Japanese nuclear energy system in transition with the SCM terminologies and viewpoints. As the result of the investigation on the boundary location of "Push type" and "Pull type", the consideration of "Pull-type" operation as well as "Push-type" by SCM tool can expand the scope of future transition strategy construction from LWR cycle to FR cycle.

Proceedings of 2011 International Congress on Advances in Nuclear Power Plants (ICAPP '11) (CD-ROM), 8 Pages, 2011/05

Comprehensive dynamic analyses of the typical Fast Reactor (FR) deployment scenarios with JSFR and related fuel cycle facilities developed in "FaCT: Fast Reactor Cycle Technology Development" project were conducted. In this study, combinations of analysis codes, which consist of two energy economic models (computable general equilibrium (CGE) model and energy system model) and dynamic analysis model for nuclear energy supply chain, were used for the dynamic analyses. As a result of the analysis, FR cycle should be deployed from 2040 to 2050 to curb the cumulative uranium resources consumption within the conventional uranium resources reported in Uranium 2009 by the OECD/NEA and the IAEA.

Impact of partitioning and transmutation on high-level waste disposal for the fast breeder reactor fuel cycle

Nishihara, Kenji; Oigawa, Hiroyuki; Nakayama, Shinichi; Ono, Kiyoshi; Shiotani, Hiroki

Journal of Nuclear Science and Technology, 47(12), p.1101 - 1117, 2010/12

 Times Cited Count:14 Percentile:72.34(Nuclear Science & Technology)

The impact of partitioning and/or transmutation (PT) technology on the high level waste management was investigated for the fast breeder reactor (FBR) fuel cycle. Three different fuel cycle scenarios involving PT technology were analyzed: (1) partitioning process only (separation of some fission products), (2) transmutation process only (separation and transmutation of minor actinides), and (3) both partitioning and transmutation. It was found that the introduction of FBR cycle without PT yields a smaller repository after 65 years of predisposal storage than the LWR after 50 years by a factor of up to 0.65. The impact of the partitioning-only process on the repository is not significant, but that of the transmutation-only process produces a reduction of area by a factor of 0.25 after 80 years of storage, and that of a coupled partitioning and transmutation by two orders of magnitude after 60 and 295 years of storage for the glass waste and the calcined waste with Sr-Cs, respectively.

Proceedings of International Conference on Advanced Nuclear Fuel Cycle; Sustainable Options & Industrial Perspectives (Global 2009) (CD-ROM), p.2559 - 2566, 2009/09

This paper treated the conceptual sides of the methodology for evaluating total nuclear energy systems in FaCT (Fast Reactor Cycle Technology Development) project of Japan Atomic Energy Agency and the efforts to develop the database system in the field. After the introduction of FaCT project and the performance targets as the basis of the total system evaluation, the way of designing the data formats and contents suitable for the nuclear energy system strategy evaluation and the evaluation methodologies were discussed. The framework of object-oriented analysis and enterprise architecture was tentatively used to streamline the nuclear materials, facilities, and socio-environmental data. Moreover, the methodologies were classified and work-flows of the evaluation were visualized. Based on those activities, the database concept was established to manage the data and methodologies for quality management and/or knowledge management.

Development of effect assessment methodology for the deployment of fast reactor cycle system with dynamic computable general equilibrium model

Shiotani, Hiroki; Ono, Kiyoshi

Nihon Genshiryoku Gakkai Wabun Rombunshi, 8(2), p.165 - 183, 2009/06

We have developed a dynamic cumputable general equivalent model which can treat the power generation technology including fast reactor cycle explicitly by decomposing the power generation sector based on a static computable general equivalent model to assess the long-term socio-economical effect of the deployment of fast reactor cycle system. We modeled the accumulation of capital by the international investments and adopted "inequivalent approach" to transit the equivalent state only in the long run. We also adopted "technology bundle" in decomposing the power generation sector. Those improvements enabled us to evaluate the electricity shares, electric power prices, supplies, production scales of various industries, and GDPs in countries and regions. In case of the deployment of FR cycle in 2050, the effect on Japanese GDP was calculated about 45 trillion JPY (Japanese Yen), and on world's GDP was about 460 trillion JPY.

Chaltikyan, V.*; Papoyan, A.*; Oshita, Hironori; Shiotani, Hiroki; Ono, Kiyoshi; Ishikawa, Makoto; Ozawa, Masaki

Journal of Radioanalytical and Nuclear Chemistry, 280(2), p.347 - 356, 2009/05

According to the review on the ecological impact by Cs-135, its nuclear transmutability and preceded isotope separation experiments on alkali metal Rb-85/87, isotope separation of Cs-133/135 by laser-chemical isotope separation method was discussed. Although high separation efficiency of 23.9 was obtained by a two cycle experiments on Rb-85/87, rather wide isotope shift between Cs-133 and Cs-135 will necessitate the application of doppler-free two-photon absorption method with further investigation of the Rydberg state and ionization.

A Preliminary comprehensive dynamic analysis of the typical FaCT scenarios with JSFR and related fuel cycle facilities

Shiotani, Hiroki; Ono, Kiyoshi; Ogawa, Takashi; Koma, Yoshikazu; Kawaguchi, Koichi

Proceedings of 2009 International Congress on Advances in Nuclear Power Plants (ICAPP '09) (CD-ROM), p.9419_1 - 9419_10, 2009/05

Dynamic analyses of the typical FR deployment scenarios with JSFR and related fuel cycle facilities developed in FaCT project was conducted. The total cash out-flows and the average electricity generation costs to 22nd century were calculated to seize the long-term economics as well as the material compositions in the nuclear facilities, the quantities of radioactive wastes generations. Several cash out-flow peaks and radioactive waste generation peaks were found because of the decommissioning and construction of the nuclear power plants and reprocessing plants for LWR spent fuel. Then, different breeding ratio, single/dual-purpose reprocessing plant, and with/without Am-Cm recycling were compared. For example, the exploration of the optimal breeding ratio between B.R. =1.1 and 1.2 for the start up stage FR was considered to be reasonable from the analysis.
