Electricity generation of Russia's nuclear power plants hit a record in 2019 to reach about 208.8 billion kilowatt-hours, up from some 204.3 billion in 2018, Russian nuclear energy company Rosenergoatom said Wednesday.

The top three generators were Rostov, Kalinin and Balakovo nuclear power plants, Rosenergoatom said in a press release.

At present, the share of nuclear generation is about 19 percent of the total electricity generation in Russia, and this ratio in the European part of the country has reached 40 percent, it said.

Russian agency RIA Novosti reported that 36 industrial power units with a total installed capacity of 30.25 gigawatts are in operation at 10 nuclear power plants in the country.

Le réacteur à neutrons rapides BN-600 voit sa licence d'exploitation prolongée jusqu'en 2025.
D'ailleurs une nouvelle prolongation sera demandée plus tard.
BN-600 licensed to operate until 2025

01 April 2020

Russian nuclear regulator Rostekhnadzor has extended the operating licence for unit 3 of the Beloyarsk nuclear power plant in the Sverdlovsk district by a further five years. The licence for the BN-600 fast reactor, which began operating in 1981, was due to expire this year.

A large-scale modernisation programme has been under way at the unit since 2009, which has affected all areas of safety, operator Rosenergoatom said. This has included the installation of a second reactor emergency protection system, an emergency dampening system using an air heat exchanger and a back-up reactor control panel. In addition, a large amount of work has been carried out on the inspection and replacement of equipment, including the replacement of the unit's steam generators.

In 2010, the BN-600 was confirmed to be in compliance with the latest safety requirements and on that basis extension of the operating life was justified until 2025. However, Rostekhnadzor only extended its license for a further 10 years of operation, requesting additional justification for the operability of irreplaceable reactor components.

Investigations conducted since then by Russian nuclear engineering company OKBM Afrikantov, part of Atomenergomash, together with the Kurchatov Institute and FSUE CRI KM "Prometey" concluded that it is technically possible to continue operation of the reactor. Based on this, Rostekhnadzor has now extended the operating licence of the 560 MWe Beloyarsk 3 until 2025.

"We have completed work to extend the life of unit 3 until 2025," said Ivan Sidorov, director of the Beloyarsk plant. "In the course of our research, we proved that the technical parameters of the BN-600 allow us to operate it until 2040." He noted that JSC Atomproject is currently developing an investment project for an additional extension of the unit's operating life. This work is expected to be completed by 2024, after which Rosenergoatom will apply to Rostekhnadzor for a licence extension until 2040.

The sodium-cooled BN-series fast reactor plans are part of Rosatom's Proryv, or 'Breakthrough', project to develop fast reactors with a closed fuel cycle whose mixed oxide (MOX) fuel will be reprocessed and recycled. In addition to the BN-600 reactor, the 789 MWe BN-800 fast neutron reactor - constructed as Beloyarsk unit 4 - entered commercial operation in October 2016. This is essentially a demonstration unit for fuel and design features for the larger BN-1200 being developed by OKBM Afrikantov.

Les Russes vont faire fonctionner le BN-800 au combustible MOX.
Rosatom to convert fast reactor to MOX fuel in 2022
10 June 2020

Unit 4 of the Beloyarsk nuclear power plant in Russia will be completely switched to uranium-plutonium MOX fuel in 2022, marking an important step towards closing the nuclear fuel cycle, Russia’s Rosatom has announced.

The 789 MWe BN-800 fast neutron reactor is currently fuelled by a 'hybrid core' - a mix of uranium and plutonium oxides arranged to produce new fuel material as it burns. The transition to MOX fuel assemblies will start in the first half of next year.

"The BN-800 reactor is to be switched from a hybrid core to a core with a full load of fuel assemblies with MOX fuel, which are being produced for us by the Mining and Chemical Combine in the Krasnoyarsk Territory and comprise uranium dioxide and plutonium dioxide in the form of pellets to be used as fuel," Vladimir Shaloumov, head of nuclear safety and reliability at Beloyarsk NPP, said.

"The BN-800 reactor, according to its design, is focused on the use of MOX fuel as one of the stages on domestic nuclear energy's path to the development of a closed nuclear fuel cycle," he added.

A closed nuclear fuel cycle will allow the creation of 'twin-component' nuclear energy, Rosatom said, "with simultaneous operation of fast and thermal neutron reactors". It added that this will "expand the fuel base of nuclear energy many times over, involving the uranium-238 isotope, ensuring the reuse of used nuclear fuel and minimising radioactive waste".

Beloyarsk 4's capacity exceeds that of the world's second most powerful fast reactor - the 560 MWe BN-600 Beloyarsk 3.

Démarrage prochain d'un réacteur sur le site de Leningrad.
Leningrad II-2 gets regulatory approval for physical start-up

17 June 2020

Russia's regulator Rostechnadzor has issued a permit for the physical start-up of Leningrad II unit 2, which completed hot tests last week. The regulator's inspection of the unit "confirmed its high degree of readiness for the start of physical launch, during which nuclear fuel will be loaded into the reactor core for the first time", state nuclear corporation Rosatom said today.
