Investigation into Automatic Shutdown of Unit 3 at Japan's Ohi Nuclear Power Plant: Damage Found in Exciter Rotating Rectifier

Kansai Electric Power reported on August 19 that Unit 3 of the Ohi Nuclear Power Plant experienced an automatic generator trip triggered by a generator loss-of-field alarm at 23:56 on August 8, followed by an automatic reactor shutdown. At the time of the event, the unit was operating stably at rated thermal power. The company stated that the event caused no radiological impact on the environment. The loss-of-field alarm is used to indicate an abnormal state in the magnetic field generated inside the generator. Following the incident, Kansai Electric conducted on-site inspections of equipment related to generator magnetic field establishment, including the generator, exciter, and automatic voltage regulator (AVR). Among these, the exciter is used to establish the magnetic field for the generator...

Indonesia Develops Cobalt-60 Gamma Irradiation Technology to Boost Biodiesel Production from Waste Cooking Oil

The Indonesian Nuclear Technology Polytechnic, under the National Research and Innovation Agency (BRIN), has recently successfully developed cobalt-60 (Co-60) gamma irradiation technology and applied it to increase biodiesel production from waste cooking oil. The study aims to explore more efficient pathways for renewable energy production while providing a new solution for the resource utilization of waste cooking oil. Dita Ariyanti, a lecturer at the Indonesian Nuclear Technology Polytechnic, stated that with continued growth in energy consumption and declining fossil fuel reserves, the need to develop alternative energy sources is becoming increasingly urgent. For Indonesia, rising energy demand and dependence on fossil fuels also pose challenges to greenhouse gas emission reduction. Waste cooking oil was previously mostly treated as household waste, and improper disposal could pollute the environment; converting it into biodiesel can reduce waste while obtaining renewable energy.

RHIC Collision Data Provides New Evidence for the Existence of the "Baryon Bridge"

August 18 news, an international team of physicists, by analyzing nuclear collision data from the STAR detector at the Relativistic Heavy Ion Collider (RHIC), has presented strong evidence that baryon number may not be carried directly by quarks, but rather transmitted by a baryon bridge formed by gluons inside protons. The related paper has been published in the journal Science. Valerie A. Lentz, Brookhaven National Laboratory Baryons, including protons and neutrons, are generally considered to be composed of three quarks. In the existing understanding, the baryon number is viewed as being uniformly distributed among the three quarks. Meanwhile, gluons also exist inside protons; they are the carriers of the strong interaction. According to the description of quantum chromodynamics, gluons may form a Y-shaped structure known as a "baryon junction" or "gluon bridge" within the proton, but this structure has long lacked direct experimental evidence.

SHINE to Advance Spent Fuel Recycling Separation Technology with Argonne National Laboratory and Others

On August 18, fusion energy company SHINE announced that it will collaborate with the U.S. Department of Energy's Argonne National Laboratory and Case Western Reserve University to apply high-throughput chemical separation technology to the nuclear fuel recycling process it is currently developing. The collaboration is carried out under the CURIE program of the U.S. Department of Energy's Advanced Research Projects Agency-Energy (ARPA-E), with additional funding led by Case Western Reserve University, and SHINE participates as a subcontractor. Spent fuel is often referred to as nuclear waste, but it retains approximately 90% of its energy potential while containing multiple reusable byproducts. In recent years, federal programs and private investment in the United States have driven renewed interest in spent fuel recycling. Argonne National Laboratory is developing a new chemical processing device called "Packed Centrifugal Equipment for Radiochemical Separation," abbreviated as PaCERS. The device generates centrifugal force exceeding normal gravity conditions through high-speed rotation to improve chemical separation efficiency, and reduces costs across multiple stages of nuclear fuel recycling through higher throughput and lower solvent usage.

Cernavoda Nuclear Power Plant Fully Shut Down Due to Falling Danube River Water Levels

Due to the continuous decline of the Danube River water level, the two units of Romania's only nuclear power plant, the Cernavoda Nuclear Power Plant, have been successively shut down. To alleviate the pressure on electricity supply, Unit 4 of the Rovinari coal-fired cogeneration plant has been put into operation, adding approximately 330 megawatts of generating capacity to Romania's power system. Romania's nuclear power company (Nuclearelectrica) previously reported that due to the sharp decline in the Danube River water level, which affected the assurance of cooling water for the reactor, Unit 2 of the Cernavoda Nuclear Power Plant was shut down in a controlled manner on the morning of August 13. The company stated that the shutdown process was carried out in accordance with procedures. At the end of July this year, Unit 1 of the Cernavoda Nuclear Power Plant had already been shut down for the same reason...

South Korea Has Not Yet Decided Whether to Include New Nuclear Power in the 12th Basic Plan for Electricity Supply and Demand

South Korea's Minister of Climate, Energy and Environment, Kim Sung-hwan, said during a meeting with reporters at the Sejong Government Complex on August 18 that the government has not yet reached a conclusion on whether to include new nuclear power plants in the 12th Basic Plan for Electricity Supply and Demand. Kim said that government policy cannot be determined solely by the personal will of the minister in charge, and it is not appropriate to make premature statements at this stage. He emphasized that related matters will be decided after going through the necessary deliberation process. Regarding whether nuclear power will be included in the 12th Basic Plan for Electricity Supply and Demand, the government plans to clarify the direction of discussion as soon as possible, including how public opinions will be reflected, how the review procedures involving experts and public participation will be structured, and what methods will be used to conduct debates or public discussions before the plan is released...
