Contamination management in these habitats is crucial, says Fukushima study The scientists examined data gathered since the 2011 accident at Fukushima-Daiichi. Courtesy IAEA. Further studies are needed to accelerate a full understanding of the way radioactive contaminants behave in forest-stream ecosystems so that measures can be developed to reduce future contamination in the event of an incident at a nuclear power plant, Japanese scientists have concluded.

Finding ways to avoid the spread of radioactive contaminants like radiocaesium to areas of human activity that lie downstream from forest streams is crucial, said the scientists, who sifted through the data gathered since the Fukushima-Daiichi nuclear accident in Japan in March 2011.

In the aftermath of Fukushima, the Japanese government performed intensive decontamination in the human-occupied parts of the affected area by removing soil surface layers.

But a major affected region consists of dense, uninhabited forests, where such decontamination strategies are not feasible. Finding ways to avoid the spread of radioactive contaminants like radiocesium to areas of human activity that lie downstream of these contaminated forests is crucial, said the scientists, from Japan’s National Institute of Environmental Studies.

First Akkuyu plant due online in 2023 with possibility of more units at Sinop and Igneada The first Akkuyu unit is expected to come online in 2023 with a further unit starting every year afterwards.

New nuclear reactors under construction and being planned in Turkey will help meet the fast-growing economy’s “massive” demand for energy and reduce the country’s dependence on polluting fossil fuels, the Italian representative of the NIATR (Nuclear Industry Association of Turkish Republic) said.

According to Turkey’s ministry of energy and natural resources, energy consumption in 2012 was 239 TWh a year, while in 2023 forecasts say it could reach as much as 478 TWh.

However, Massimo Giorgi of NIATR told NucNet that the current energy mix will not meet demand and the lack of reliable, diversified, low-cost energy is an obstacle to Ankara’s economic plans.

Once fully operational, the $20bn Akkuyu nuclear power station, where Turkey is building four 1,114-MW pressurised water reactor units supplied by Russia, will provide about 10% of the country’s total electricity generation.

Kyushu Electric also considering lifetime extension for plant Sendai-2 had been offline since mid-October for scheduled maintenance and refuelling. Japan’s Kyushu Electric Power has restarted the Sendai-1 nuclear power plant in southwestern Japan after scheduled maintenance and refuelling.

The utility restarted the 846-MW pressurised water reactor unit on Saturday, a spokesperson said.

The reactor had been offline since 17 October when the company also started a special inspection that is required to have its operating life extended beyond 40 years.

The special inspection is continuing and the company has not decided whether or not it would apply for approval to extend operation beyond 40 years, Reuters reported.

Sellafield announced that it had packaged all foreign-owned wasted ready for return. The work is part of the closing out of commercial reprocessing contracts. Sellafield received used nuclear fuel from around the world to be reprocessed at its Thorp plant, generating £9 billion ($11.9bn) in revenue for the UK. Waste created during the process remains the property of overseas customers who are contractually obliged to take it back.

New venture is focused on GEH’s BWRX-300 reactor technology PKN Orlen and Synthos Green Energy have signed an agreement establishing a joint venture that aims to commercialise microreactor and small modular reactor technologies in Poland, in particular GE Hitachi Nuclear Energy’s (GEH) BWRX-300.

PKN Orlen, a state-controlled fuels and energy company, said in a statement that the new venture will be called Orlen Synthos Green Energy. Synthos is a chemicals company and part of the largest private industrial group in Poland.

GEH and Synthos announced in October 2019 an agreement to collaborate on potential deployment applications for the BWRX-300 SMR in Poland. 

Synthos has said it is interested in nuclear power for obtaining affordable, on-demand, carbon-free electricity.

The agreement covers a number of areas of reactor development and deployment, including financing, site selection and the production of energy and heat for the companies’ own needs and for municipal and commercial customers.
