First Validation of Novel PRI Technology: Existing PET Tracers Can Image Tissue Microenvironment
August 6, 2026 - A joint research team from the Graduate School of Engineering at the University of Tokyo and the University of York in the UK announced that they have established a novel geometric imaging principle utilizing positron three-photon decay and successfully validated Positronium Ratio Imaging (PRI) technology for the first time. This method can be used in conjunction with existing clinical PET tracers and is expected to provide a new means of observing tissue microenvironments in nuclear medicine imaging. Conceptual diagram of next-generation nuclear medicine imaging utilizing positron-3-photon decay. Current clinical PET scans primarily rely on the positron two-photon annihilation process to visualize the distribution and accumulation of tracers in the body, but they provide limited information on microenvironmental factors such as tissue hypoxia that are associated with disease malignancy...

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.

New Decommissioning Plan for Fukushima Daiichi: Priority on Internal Investigation of Unit 3 Before Fuel Debris Retrieval
The Nuclear Damage Compensation and Decommissioning Facilitation Corporation of Japan released on August 6 an outline of the 2026 edition of the "Decommissioning Strategic Plan," proposing technical approaches for the decommissioning of Tokyo Electric Power Company's Fukushima Daiichi Nuclear Power Station. The plan highlights that, for the large-scale retrieval of melted fuel debris at Unit 3, expected to commence in or after fiscal year 2037, priority should currently be given to internal investigations of the reactor building to provide a more reliable basis for subsequent engineering plans. The plan states that the fuel debris retrieval method being studied by TEPCO still requires further improvement in certainty, with the key prerequisite being an understanding of the actual internal conditions of the reactor. Due to the high radiation levels of the water inside the unit following the accident...

South Korea Advances First Domestic Commercial Production of Lu-177 Using Wolsong Heavy Water Reactors
Korea Hydro & Nuclear Power (KHNP) plans to use the heavy water reactors at the Wolsong Nuclear Power Plant to produce, for the first time domestically, the radioisotope lutetium-177 (Lu-177) for cancer treatment. Currently, South Korea relies entirely on imports for this material, which imposes cost pressures and supply instability on local radiopharmaceutical companies such as Cellbion and FutureChem. Industry experts generally believe that domestic production will help build a diversified supply chain and shorten transportation times. The primary goal of this plan is to achieve commercial production of Lu-177, with pilot production expected in 2028 and full-scale production commencing in 2031. Subsequently, KHNP will expand production to include cobalt...

Site Handover for Poland's First Commercial Nuclear Power Plant to Bechtel
New progress has been made in the construction of Poland's first commercial nuclear power plant. The Lubiatowo-Kopalino site in the Pomerania region of northern Poland has been handed over to Bechtel of the United States, and earthworks at the project site are underway. Polskie Elektrownie Jądrowe (PEJ), Poland's state-owned project company, stated that Bechtel has replaced PEJ as the site coordinator for the project. Under the Polish government's earlier arrangement, the nuclear power plant will feature three Westinghouse Electric Company AP1000 pressurized water reactor units. In 2023, Westinghouse Electric Company and Bechtel formed a consortium to jointly advance project implementation. The nuclear power plant is sited in the Lubiatowo-Kopalino area along the Baltic Sea coast in Poland.

A batch of radioactive waste from the Korea Atomic Energy Research Institute deemed unsuitable for disposal due to documentation discrepancies
According to disclosures by relevant parties on August 5, a batch of radioactive waste shipped last year by the Korea Atomic Energy Research Institute (KAERI) to the low- and intermediate-level radioactive waste disposal facility (RWDF) in Gyeongju, North Gyeongsang Province, was deemed unsuitable for batch disposal due to inconsistencies between the declared documentation and actual contents. The Korea Radioactive Waste Agency (KORAD) conducted inspections after receiving the waste. KAERI shipped a total of 694 drums of radioactive waste to the disposal facility last year, of which 69 drums were inspected, and 32 were found to be non-compliant. The primary reason for non-compliance was discrepancies between the contents of the documents submitted by the institute and the actual inspection results after receipt. As a result, this batch of waste from the Korea Atomic Energy Research Institute...

Czech nuclear safety officials say domestic nuclear power plants have sufficient cooling water for both existing and new units
Droughts across parts of Europe are affecting the operation of some nuclear power plants. Due to low water levels and flow rates in the Danube River, two reactors at Romania's Cernavodă Nuclear Power Plant have been shut down, and Hungary's Paks Nuclear Power Plant also faces the risk of a complete shutdown. Štěpán Kochánek, Chairman of the Czech State Office for Nuclear Safety (SÚJB), stated that plant operators should not be allowed to continue operating units at full power when cooling water is insufficient, and that related shutdown measures are conservative actions predefined in operating procedures. Kochánek explained that reactor shutdowns are not an unusually rare operation. Unit shutdown typically involves gradually reducing reactor power, inserting control rods, and bringing fission reactions to a minimal level or complete cessation. After shutdown, the reactor still requires cooling, but the demand for cooling water volume and capacity is significantly lower than during full-power operation. He noted that this process shares similarities with planned outages such as refueling overhauls and is a standardized procedure that operators should master.
