Fukushima Daiichi Nuclear Power Station begins 23rd discharge of treated nuclear-contaminated water

Fukushima Daiichi Nuclear Power Station begins 23rd discharge of treated nuclear-contaminated water

At 11:29 on August 31, Fukushima Daiichi Nuclear Power Station began its fifth discharge of treated nuclear-contaminated water in fiscal year 2026 and the 23rd overall. The operation is scheduled to last 19 days, concluding on September 18, with an estimated discharge of approximately 7,800 tonnes of nuclear-contaminated water diluted with seawater, equivalent to the capacity of about 8 storage tanks. The total tritium content is estimated at approximately 1.2 trillion becquerels. The reactors of Units 1 to 3 at Fukushima Daiichi still contain nuclear fuel that melted and solidified during the accident, known as fuel debris. Groundwater and rainwater that come into contact with this fuel debris form contaminated water. Since the discharge of treated nuclear-contaminated water began in August 2023, Fukushima Daiichi has cumulatively released approximately 173,000 tonnes, equivalent to about 173 storage tanks' capacity.

Japan to Build Fusion Tritium Fuel Research Base in Aomori Prefecture

Japan to Build Fusion Tritium Fuel Research Base in Aomori Prefecture

Japan's Ministry of Education, Culture, Sports, Science and Technology (MEXT) has decided to establish a new fusion power generation research base in Aomori Prefecture, focusing on tritium fuel handling technology. The base will target the development needs of fusion demonstration projects in the 2030s, promoting joint research and development among industry, government, and academia. MEXT plans to include approximately 100 billion yen in fusion development-related funding in its budget request for the next fiscal year. Fusion power generation releases energy through the fusion reaction of deuterium and tritium nuclei, a principle similar to the energy generation process inside the sun. Unlike traditional nuclear power that relies on nuclear fission chain reactions, fusion reactions carry a lower risk of runaway, leading many countries to view it as an important direction for future energy technology...

US Inertia Fusion Fuel Preparation Time Significantly Reduced

US Inertia Fusion Fuel Preparation Time Significantly Reduced

US fusion startup Inertia Enterprises said it has made progress in inertial fusion energy fuel preparation in collaboration with Lawrence Livermore National Laboratory (LLNL), reducing the time required for the critical step of forming a cryogenic deuterium-tritium fuel layer from potentially several days in the past to tens of minutes. The company said this achievement completes a key task in the first phase of its commercial fusion power plant development goals. The fundamental approach of inertial fusion energy involves using high-energy lasers to compress and heat small targets containing deuterium-tritium fuel, bringing the fuel to ignition conditions and releasing energy. The National Ignition Facility (NIF) has already...

UK's Materials Detritiation Facility at Culham Resumes Operations to Support JET Fusion Decommissioning Materials Research

UK's Materials Detritiation Facility at Culham Resumes Operations to Support JET Fusion Decommissioning Materials Research

The UK Atomic Energy Authority recently announced that the Materials Detritiation Facility (MDF) at Culham has resumed operations following a 12-month engineering shutdown and upgrade. Experimental data produced by the facility has already been used to support research related to the removal of materials from the Joint European Torus (JET) device, providing a basis for waste management strategies under the JET Decommissioning and Repurposing (JDR) project. Over three years of plasma operations, deuterium-tritium (DT) experiments conducted at JET have left residual amounts of tritium in the tokamak's walls and internal components. This phenomenon is associated with tritium's tendency to enter materials under high-power fusion operating conditions. For JET decommissioning work, accurately determining the tritium...

German team achieves first separation of tritium-containing hydrogen isotope mixtures using silver-exchanged zeolites

German team achieves first separation of tritium-containing hydrogen isotope mixtures using silver-exchanged zeolites

A team at the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) and partners recently demonstrated a new method for separating hydrogen isotopes using silver-containing zeolites, successfully separating hydrogen isotope mixtures containing radioactive tritium through a porous solid material for the first time. The research findings were published in Nature Communications. Future fusion power plants will require not only high-temperature plasma and strong magnetic fields during operation, but also a stable fuel cycle system for recovering, separating, and reusing deuterium and tritium. Inside a fusion reactor, deuterium and tritium participate in reactions and release energy, but the fuel is not completely consumed, and the residual gas may also contain ordinary hydrogen (protium), forming a mixture of protium, deuterium, and tritium...

Radioactivity test results for agricultural and fishery products in North Chungcheong Province, South Korea, pass standards in first half of the year

The Chungcheongbuk-do Institute of Health and Environment announced on August 7 that it conducted radioactivity safety testing on agricultural and fishery products sold and used within the province in the first half of this year, and the results showed that all relevant samples met food radioactivity safety standards. The testing covered 119 types of agricultural products and 274 types of fishery products sold at large supermarkets, local food direct-sale stores, or used as ingredients for school meals. Testing items included indicators such as radioactive iodine, radioactive cesium, and tritium. The test results showed that the levels of radioactive iodine and radioactive cesium in the samples did not exceed the permissible limit of 100 Bq/kg for food radioactivity; tritium was not detected in any of the 80 seafood samples. The relevant test results can be found on the Chungcheongbuk-do Institute of Health and Environment website.
