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

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

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...

IAEA Publishes Report on Aging Management of Spent Fuel Dry Storage Systems

IAEA Publishes Report on Aging Management of Spent Fuel Dry Storage Systems

The International Atomic Energy Agency (IAEA) has published the findings of a decade-long study on aging management of spent fuel dry storage systems. According to IAEA estimates, by the end of 2024, spent fuel discharged from nuclear power plants worldwide had exceeded 400,000 tonnes of heavy metal (tHM). Of this, 106,000 tHM is in dry storage, a long-term storage method that is becoming increasingly common compared with wet storage. Most IAEA member states are still decades away from commissioning permanent spent fuel repositories, which means dry storage systems will likely need to continue operating safely beyond their design lifetimes. Wet storage has been in operation for decades, and the IAEA states that aging management of such facilities is generally well understood. Utilities choose dry storage for its passive safety features, and many dry storage facilities have already received license extensions. The IAEA expects demand for dry storage to continue growing, with service periods extending well beyond the original 20-to-40-year licensing terms, potentially exceeding 120 years. Aging management programs (AMPs) are therefore needed to verify continued safe operation.

Final Voyage Completed for Rebar Cage Sea Transport to Hinkley Point C Nuclear Power Station

Final Voyage Completed for Rebar Cage Sea Transport to Hinkley Point C Nuclear Power Station

This summer, the cargo vessel Anfield Peak departed from the Port of Bristol in the UK, heading to Hinkley Point C Nuclear Power Station in Somerset. This marked the vessel's final voyage for the related transport mission. Previously, it had made over 100 round trips between the two locations, delivering factory-prefabricated rebar cages to the nuclear construction site. These rebar cages are large in volume and high in density, serving as critical foundational components in civil engineering construction. Under traditional practices, such rebar cages are typically prefabricated on-site before concrete pouring. The Hinkley Point C project, however, has shifted part of the rebar cage prefabrication process to a factory in Bristol, with the cages then transported by sea to the site for installation...
