Ikata Nuclear Power Station Unit 3 in Japan briefly deviated from operational limits due to abnormal signals in protection system instrumentation

Shikoku Electric Power Co. reported on August 27 that abnormal signals from safety protection system instrumentation appeared in the central control room of Ikata Nuclear Power Station Unit 3, which was in normal operation, indicating that one channel of the overtemperature ΔT related instrumentation was unreliable. The operator determined at 22:10 on August 26 that the unit had deviated from the operational limits stipulated in the Reactor Facility Security Regulations. On-site confirmation showed that the unreliable signal originated from 1 of the 4 channels of the overtemperature ΔT protection function. Overtemperature ΔT is one of the reactor automatic trip elements, used to protect in-core fuel; its limit value is calculated based on parameters such as reactor power, pressurizer pressure, and...

Huzhou, Zhejiang Launches Phase I "Drug-Device Combination" Clinical Trial for the Province's First BNCT System

Recently, the Boron Neutron Tumor Treatment Center at Huzhou Hospital Affiliated to Zhejiang University School of Medicine has drawn attention with the introduction of the province's first Boron Neutron Capture Therapy (BNCT) system. Previously, the system had already initiated a Phase I BNCT drug-device combination clinical trial. According to the system developer, Huapeng Neutron Technology (Hangzhou) Co., Ltd., BNCT is a radiotherapy technique combining drugs and devices, with its core lying in the coordinated use of boron-containing drugs and neutron irradiation. After entering the human body, the boron-containing drug can be absorbed by tumor cells; subsequent neutron beam irradiation triggers a localized reaction to achieve targeted radiotherapy against tumor cells. Unlike conventional radiotherapy, which typically employs fractionated irradiation over a longer treatment course, BNCT emphasizes selective targeting of tumor cells, aiming to reduce damage to surrounding healthy tissues and lower radiotherapy-related side effects such as hair loss and immunosuppression.

Busan, South Korea Reports No Abnormal Radiation Detected in Seawater and Seafood Three Years After Fukushima Discharge

Busan Metropolitan City stated on August 24 that since the discharge of contaminated water from the Fukushima nuclear power plant began in 2023, the city has continuously conducted radiation monitoring and analysis of coastal seawater and seafood. The results show that the safety conditions of Busan's waters and seafood remain stable with no abnormal changes detected. According to Busan Metropolitan City, seawater radioactivity testing is currently conducted at 26 coastal points. Among them, samples from 14 coastal locations including Haeundae, Gwangalli, Dadaepo, Songdo, and Songjeong are analyzed by the Busan Metropolitan City Institute of Health and Environment and local university research institutions. Test results show that the concentrations of relevant radionuclides are far below the World Health Organization drinking water standards, with cesium-134,...

Unit 3 of Beloyarsk NPP begins scheduled maintenance and equipment modernization

Unit 3 of Russia's Beloyarsk NPP entered scheduled preventive maintenance on August 18. This outage maintenance will be used for fuel reloading, equipment maintenance, and preventive repairs, along with partial modernization efforts to maintain reliable unit operation and improve equipment performance. The unit features a BN-600 sodium-cooled fast neutron reactor. During the maintenance period, the plant will carry out major repairs on the BN-600 reactor facility and replace 9 guide tubes in the control and protection system. Such operations are uncommon and are typically performed approximately once every 10 years. According to the maintenance schedule, the plant will also repair the unloading lift device and conduct operational monitoring inspections of the reactor pressure vessel metal...
