Description

[Technical Field]

[0001] This invention relates to a nuclear battery for a safety metal container device that contains rare earth waste, which is collected from (rare earth) rare earth ore or seabed rare earth mud, separated and refined, and the rare earth waste resulting from this process is sealed in a safety metal container. The ionizing radiation emitted from the radioactive materials contained in the rare earth is then converted into electricity for use. [Background technology]

[0002] The Japanese government has adopted a policy of stockpiling rare earth elements to prepare for potential disruptions in imports. Given Japan's limited mineral resources, rare earth imports are currently concentrated in China (63%), Vietnam (32%), and Thailand (5%) (according to Ministry of Finance data), suggesting a need to increase imports from sources other than China. Efforts have begun to aim for domestic production of rare earth elements in Japan. A research vessel, led by the Cabinet Office, departed from Shimizu Port in Shizuoka City on January 12, 2026, to mine rare earth-containing mud off Minamitorishima Island in the Ogasawara Islands.

[0005] As part of the Cabinet Office's Strategic Innovation Promotion Program (SIP), rare earth element mud will be recovered from the seabed at a depth of approximately 6,000 meters within Japan's exclusive economic zone (EEZ) off Minamitorishima Island. If rare earth elements can be procured domestically in Japan, a country with limited mineral resources, it would be a significant advantage for industry. The elements contained in the rare earth element mud off Minamitorishima Island include dysprosium (Dy), neodymium (Nd), samarium (Sm), yttrium (Y), gadolinium (Gd), and cerium (Ce). However, charged particle radiation (alpha and beta rays) and electromagnetic waves (gamma rays) contained in the rare earth waste generated after the separation and refining of rare earth elements are considered a problem. Unlike terrestrial ores, the rare earth element mud on the seabed contains almost no radioactive materials such as thorium (Th) and uranium (U), which may simplify the processing of the rare earth waste generated after refining, but the alpha and beta rays and electromagnetic waves (gamma rays) remain a concern. There are concerns that China may strengthen export restrictions on rare earth elements to Japan. Japan imports rare earth elements from China, Vietnam, and Thailand. These rare earth elements are imported after the ore has been crushed, separated, and refined. However, the rare earth waste generated after refining includes radioactive waste containing elements such as uranium (U) and thorium (Th), which are used in nuclear fuel, and the methods for processing, disposing of, or utilizing the refined rare earth elements are unclear. While the rare earth sediment off the coast of Minamitorishima, Japan, is said to contain very little uranium (U) or thorium (Th), there are issues with the rare earth waste contained after refining, depending on the depth of the deposited rare earth sediment. This invention relates to a nuclear battery for a safety metal container device containing rare earth waste, which involves sealing rare earth waste in a cubic or rectangular safety metal container and utilizing power generated by connecting in series the DC electromotive force of a tandem CVD diamond cell module structure that converts the charged particle beams (alpha and beta rays) and electromagnetic waves (gamma rays and X-rays) of ionizing radiation emitted from radioactive materials contained in the rare earth. [Means for solving the problem]

[0006] In a nuclear battery using a safety metal container device containing rare earth waste, rare earth ore or seabed rare earth mud is recovered, separated, and the resulting rare earth waste is sealed in a cubic or rectangular safety metal container, and the ionizing radiation emitted from the radioactive material contained in the rare earth is converted into electricity for use. This nuclear battery for a safety metal container containing rare earth waste is characterized by its ability to store, preserve, bury, or geologically dispose of the safety metal container, utilize power generated by a series connection of DC electromotive forces from tandem CVD diamond cell module structures that convert the charged particle beams (alpha and beta rays) and electromagnetic waves (gamma rays and X-rays) of ionizing radiation emitted from radioactive materials contained in the rare earths, and utilize power for long-term conversion power generation after the container is buried or disposed of in a geological site.

[0007] This is a nuclear battery for a safety metal container device containing rare earth waste. It involves recovering rare earth sediment from the seabed, separating and refining it, and then sealing the resulting rare earth waste in a cubic or rectangular safety metal container. The device utilizes power generated by the DC electromotive force of a tandem CVD diamond cell module structure connected in series, which converts the charged particle beams (alpha and beta rays) and electromagnetic waves (gamma rays) contained in the rare earths. This power is used for long-term conversion power generation after the storage, preservation, burial, or geological disposal of the safety metal container. [Effects of the Invention]

[0010] Rare earth elements (scandium (Sc), yttrium (Y), and lanthanides) are counted as one type, but waste from rare earth mud requires treatment of charged particle beams (alpha and beta rays) and electromagnetic waves (gamma rays). Rare earth waste from ore contains actinides such as uranium (U) and thorium (Th), which are used in nuclear fuel, but transition metals such as rhodium (Rh), iridium (Ir), and ruthenium (Ru) are not included in rare earth elements. Rare earth waste generated after crushing, separating, and refining (rare earth) ore contains radioactive materials, and requires treatment of ionizing radiation emitted from radioactive materials, including charged particle beams (alpha and beta rays), electromagnetic waves (gamma rays and X-rays), and uncharged particle beams (neutrons). The rare earth waste generated after recovering, separating, and refining the seabed rare earth sediment requires treatment with charged particle beams (alpha and beta rays) and electromagnetic waves (gamma rays). The elements contained in the seabed rare earth sediment off Minamitorishima include dysprosium (Dy), neodymium (Nd), samarium (Sm), yttrium (Y), gadolinium (Gd), and cerium (Ce), and therefore require waste treatment. This invention is a nuclear battery for a safety metal container device that encloses rare earth waste. Rare earth waste, which is produced after crushing, separating, and refining rare earth ore, is sealed in a cubic or rectangular safety metal container. The device utilizes power generated by a perpetual conversion power system, which is created by converting the charged particle beams (alpha and beta rays) and electromagnetic waves (gamma rays and X-rays) of ionizing radiation emitted from the radioactive material contained in the rare earth into DC electromotive force, which is then connected in series using a tandem CVD diamond cell module structure.

[0011] This is shown in the reference side view and cross-sectional view in Figure 1. A thallium layer (TI) 2 and a lead layer (Pb) are arranged in parallel on a cubic or rectangular metal container 1, and a 45-degree angle folded perforated metal plate 20 is provided in the circulating water cooling layer 8 or forced air circulation cooling layer 8 of the cooling metal container 5. This is a structural reinforcement of the cooling metal container 5 plane, and the heat generated by the tandem type CVD diamond cell module structure 10 covered with a radiation-resistant and insulating CVD diamond thin film layer 9 is dissipated using the circulation flow of a fluid (gas or liquid). The flow velocity of the fluid whose temperature rises due to heat dissipation increases, resulting in turbulence or vortex. The 45-degree angle folded perforated metal plate 20 provided in the circulating water cooling layer 8 or forced air circulation cooling layer 8 causes the fluid flow to change from laminar to turbulent or vortex, but the perforations 21 disperse or mitigate this, and the flow velocity due to the overall temperature rise of the fluid due to heat dissipation becomes almost uniform, and it is discharged or released from the circulating water discharge hole 7 or forced air circulation discharge hole 7. Furthermore, the ∠45-degree folded perforated metal plate 20 is provided in the circulating water cooling layer 8 or forced air circulation air cooling layer 8 of the cooling metal container 5 to withstand the load of rare earth waste, in a nuclear battery in a safety metal container device that encloses rare earth waste.

The "neptunium series" starts with neptunium-237 ( 237 Np) and is considered to stabilize at thallium-205 ( 205 Th), but currently, there are four known classifications as decay series of artificial radioactive elements starting from plutonium-241 ( 241 Pu).
