“…Menurut [2], Thorium-232 yang merupakan bahan bakar fertille dapat menjadi bahan bakar fisille K 24323-145 dengan memproduksi Uranium-233 melalui proses penangkapan neutron. Jika Thorium-232 menangkap neutron dengan energi rendah akan menghasilkan isotop 𝑈 233 .…”

ABSTRAK: Desain Neutronik Reaktor Cepat Berpendingin Helium 900 MWth bahan bakar Thorium Mix Oxide telah dilakukan. Dibutuhkan penambahan bahan bakar fisil Pu 239 karena thorium alam tidak memiliki isotop fisil. Perhitungan dilakukan menggunakan simulasi komputasi dengan program SRAC. Reaktor ini menggunakan Skema Burnup MCANDLE arah Radial dengan membagi teras reaktor menjadi 10 bagian. Setelah 10 tahun periode burn up, bahan bakar di shuffling secara radial dari bagian 1 ke bagian 2, bagian 2 ke bagian 3, begitu seterusnya sampai bahan bakar di bagian 9 di-shuffling ke bagian 10 sehingga bahan bakar bagian 10 dikeluarkan dari teras reaktor dan bahan bakar baru ditempatkan di bagian 1. Hasil perhitungan menunjukkan bahwa komposisi bahan bakar 86% Th dan 14% Pu 239 dalam keadaan kritis sampai pada tahun ke 4 ditunjukkan dengan nilai k eff 1,012 dengan reaktivitas 0,0119.

“…Given that countries with potentially high thorium reserves are facing increasing macroeconomic risk, it would be prudent to consider developing thorium-based fuels for nations with different needs. A market segment to consider for using thorium could be nations seeking to control excess supply of plutonium, for example, the United Kingdom and Japan [209][210][211][212].…”

To meet future global needs for energy and green technology, it is prudent to identify energy sources and technology that may potentially be economically beneficial. Thorium-based fuels with nuclear technology, such as the Canadian heavy-water reactor, have been proposed as a way to meet those global needs, though economic challenges persist in deploying thorium-based fuels. Therefore, economic strategies to overcome the economic challenges in deploying thorium-based fuels are needed. To identify potential strategies for advancing the deployment of thorium-based fuels, this paper conducts a historical examination of the economics of thorium fuel cycles to identify economic factors that can influence a country’s development of thorium-based fuel cycles. In particular, this paper reviews the economic issues associated with Canada’s experience in deploying thorium-based fuel cycles. The study finds that the existence of natural resources and the associated price, a nuclear fuel cycle’s costs, a country’s international trade balance position and economic growth policies, the profitability of the electrical power and nuclear industry, and the technical and economical characteristics of the nuclear reactor developed in a country may all influence the adoption of a thorium-based fuel cycle. Furthermore, recent advancements in developing thorium-based fuel cycles are suggested as a possible way of bridging the technical and economic gap between near-term and long-term implementation of thorium-based fuel cycles that may overcome current economic challenges.

Nuclear fuel is not a renewable resource, and reserves of uranium and other fuel materials must be carefully stewarded to ensure the long‐term operability of nuclear energy systems. This article discusses the geological and geographical distribution of uranium resources globally, including unconventional sources such as uranium dissolved in seawater and surplus military nuclear materials. The growth of production capacity, supply, and demand relationships are presented under different scenarios. Secondary sources of uranium fuel, as well as nuclear fuel cycle options that can increase the quantity of nuclear fuel producible from a given starting quantity of natural uranium, such as the use of mixed‐oxide fuels and underfeeding of enrichment plants, are introduced. The article also includes a discussion of breeder reactors, which can be fueled with a much broader range of nuclear fuel types than currently used reactor technologies, greatly increasing the proportion of natural uranium which can be used within nuclear power reactors. Finally, thorium is introduced as an alternative nuclear fuel to uranium, which is more abundant than uranium but brings unique technical challenges. At the start of 2017, globally there were estimated to be approximately 6,142,000 tonnes of identified uranium resources recoverable at a cost of less than $130 per kg of uranium. This should be sufficient to meet the needs of a projected nuclear reactor fleet for several decades, even under high growth scenarios for nuclear energy. As such, there is currently little commercial drive toward the use of alternative nuclear fuel types.
