An International Atomic Energy Agency (IAEA) Integrated Safety Assessment for Research Reactors (INSARR) team of experts said the Philippines is committed to the safe operation of the Philippine Research Reactor-1 (PRR-1) Subcritical Assembly for Training, Education & Research (SATER) facility. This followed completion of recent commissioning tests and the start of its utilisation for training and education. The team also found the need for further improvement in the reactor’s operational organisation structure, its maintenance and operating procedures.

South Korea has begun preparations to begin building a nuclear fusion reactor after 2035. It aims to produce electric power around 2050 in a bid to keep up with the intensifying international competition for the future clean and limitless energy, the Ministry of Science, Information & Communication Technology said.

Construction will slip and zero carbon goal become harder TerraPower said its Natrium reactor could be delayed at least two years because of a lack of advanced fuel sources outside Russia. Courtesyy TerraPower. If the US does not work out how to prepare uranium fuel for advanced reactors, the startup of first-of-a-kind plants on which spent billions of dollars have been spent will be delayed, the Breakthrough Institute research centre said.

Construction of subsequent plants will slip into the future, and the goal of a zero-carbon energy system by mid-century, already hard, will become harder.

Breakthrough said fuel was needed for reactors designed to work well with wind and solar on the grid, to replace coal plants, and to do other kinds of work besides making electricity – all in the quest for a zero-carbon economy.

“Construction of subsequent plants will slip into the future, and the goal of a zero-carbon energy system by mid-century, already hard, will become harder,” Breakthrough said.

Some advanced reactors need high assay low-enriched uranium, or Haleu, fuel. Without it “we are likely to have the first few advanced reactors waiting to start up, with no fuel for them in sight,” Breakthrough said.

International Atomic Energy Agency (IAEA) Director General Rafael Mariano Grossi arrived in Ukraine on 29 March for talks with senior government officials on the IAEA’s planned delivery of urgent technical assistance to ensure the safety and security of the country’s nuclear facilities and help avert the risk of an accident that could endanger people and the environment.

Scientists at the US Pacific Northwest National Laboratory (PNNL) have obtained some initial results from their investigations into cubes of uranium which were part of Nazi Germany’s nuclear weapons programme, the American Chemical Society (ACS) reported on 24 August. Brittany Robertson, a doctoral student who works at PNNL will present the work at ACS Fall 2021 meeting.

A team of government researchers in China have unveiled the design for a commercial nuclear reactor that is expected to be the first in the world that does not need water for cooling, the South China Morning Post (SCMP) reported on 19 July. This will allow the facilities to be built in remote desert regions to provide power for more densely populated areas. The design includes a molten salt reactor, which is powered by liquid thorium rather than uranium, making it safer in the event of a leak. The molten thorium would cool and solidify quickly, dispersing less radiation into the environment. Construction of the first commercial reactor should be completed by 2030 and the government plans to build several in the deserts and plains of central and western China, SCNP noted.

Gas-cooled reactor unit has been offline because of cracking in graphite bricks The Hunterston B nuclear power station in Scotland. Courtesy EDF energy. The UK’s Office for Nuclear Regulation has given permission for the Hunterston B-2 nuclear power plant in Scotland to return to service for a limited period of operation.

The ONR said the permission is for operation up to a total of 16.25 terawatt days, or about six months operation.

The ONR’s assessment focussed on whether cracking observed in the graphite bricks that form the reactor core of Hunterston B-2 could compromise its fundamental nuclear safety requirements.

Those requirements are:

The UK’s Office for Nuclear Regulation (ONR) has given permission for EDF Energy to restart Reactor 4 at its Hunterston B nuclear power plant in Scotland. Permission is for up to 16.025 terawatt days, which is about four months of operation, ONR said yesterday.
