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.

Construction of Proton Therapy Center in Ulsan, South Korea Faces Hurdles: Government Funding Allocation Adjustments Impact Project Progress

The proton therapy center construction project in Ulsan, South Korea, has recently encountered obstacles to progress. The project was once regarded as a key component in improving the regional cancer treatment system in southeastern South Korea, but due to shifts in government medical financial support priorities, the difficulty of securing large-scale national funding independently has increased significantly. According to information from Ulsan City on August 6, Ulsan City completed the feasibility study and basic planning services for the proton therapy center construction in March of last year and began seeking national funding. However, the Ministry of Health and Welfare responded that it would be difficult to provide large-scale project funding to Ulsan City alone. Previously, Ulsan City had planned to establish a proton therapy center to build a system enabling cancer patients to undergo surgery...

Newcleo Initiates U.S. Regulatory Pre-Application Engagement for MOX Fuel Facility, Accelerating Advanced Reactor Fuel Supply Chain Development

Advanced reactor and nuclear fuel company Newcleo has initiated regulatory pre-application engagement with the U.S. Nuclear Regulatory Commission (NRC) for a mixed oxide (MOX) fuel fabrication facility, with plans to advance construction at the Savannah River Site in South Carolina. This move indicates that the company is not only advancing the licensing of its advanced reactor itself but also seeking to establish supporting fuel supply capabilities in parallel, aiming to mitigate fuel bottlenecks in future commercial deployment. The submitted regulatory engagement plan represents a key step prior to formal license application, with the core objective of communicating with regulators in advance on facility design, safety standards, review scope, and key technical issues. Newcleo previously submitted its regulatory engagement plan for the LFR-AS-200 lead-cooled fast reactor to the NRC in July...

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...

Radiation detector malfunction at Unit 2 of Japan's Onagawa Nuclear Power Plant causes hundreds of abnormal reading fluctuations

Tohoku Electric Power Company of Japan announced on August 6 that a detection equipment malfunction occurred at Unit 2 of the Onagawa Nuclear Power Plant, located in Onagawa Town and Ishinomaki City, Miyagi Prefecture. The issue involved detectors used to measure radiation levels in the main steam lines, which transport steam generated by the reactor to the turbine. Among the four detectors, one displayed readings in the central control room that surged and dropped sharply, repeating hundreds of times. Based on publicly available information, Tohoku Electric has classified this incident as a detector malfunction rather than an abnormal release of radioactive materials or a sudden change in reactor operating conditions. The company stated that the situation does not constitute a problem under security regulations, meaning that from...

U.S. Environmental Groups Sue, Claiming Turkey Point Nuclear Plant License Renewal Requires Additional Environmental Review

The U.S. Nuclear Regulatory Commission (NRC) faces a legal challenge over its renewal of operating licenses for Units 3 and 4 at the Turkey Point nuclear power plant near Miami, Florida. Florida environmental group Miami Waterkeeper Inc. has petitioned the U.S. Court of Appeals for the District of Columbia Circuit, arguing that the agency failed to follow proper procedures during the license renewal process and overlooked significant environmental concerns. At the heart of the lawsuit is Miami Waterkeeper's assertion that the NRC should not have proceeded with the license renewal after denying the group's hearing request. The organization had participated in the related administrative proceedings and raised objections concerning the plant's environmental impact review, but the NRC concluded those proceedings in March of this year...
