Rosatom, Russia’s state nuclear corporation, will this month begin work at the future site of a small-scale nuclear power plant in the far eastern Siberian territory of Yakutia, Alexei Likhachev, the company’s head, said in a video message in late December.

Rosatom reports it has reached an agreement with Yakutia’s regional government laying out parameters for pricing energy that will be produced by the nuclear plant, which is expected to be completed by 2028 in Yakutia’s Ust-Yansky district.
The backbone of the Yakutia plant, according to materials released by Rosatom, will be the RITM-200 reactor, a 50-megawatt unit that Russia is debuting on its most recent line of new-generation nuclear icebreakers. One has already gone into service aboard the Arktika nuclear icebreaker, the lead vessel in the 22220 Project icebreakers, four more of which are under construction at the Baltic Shipyard in St Petersburg.

Rosatom claims these reactors are an improvement on the KLT-40 reactor type, which powers the Akademik Lomonosov, and has also long been used for nautical purposes. The RITM-200s, the company says, feature compact design, modularity, a short construction period, and high safety standards, with a service life or more than 60 years. The group said the SMR nuclear plant also can produce low-carbon hydrogen, which could be used in various industries.

Russia retires Leningrad 2 RBMK

10 November 2020

The Leningrad 2 nuclear power unit in in Sosnovy Bor in Western Russia was shut down permanently today. The RBMK, which has been in operation for 45 years, is to be replaced by Leningrad II-2, a VVER-1200, which on 6 November received regulatory approval to start pilot operation.

Russian state nuclear corporation Rosatom said Leningrad 2 was shut down for subsequent decommissioning at 12:31am Moscow time. The reactor was shut down in accordance with the technological regulations and disconnected from the unified power system of Russia without incident, Rosatom said.

In accordance with federal regulations, a shutdown power unit is considered to be in operation without generation until the moment of complete removal of nuclear fuel, which is completed within four years, Rosatom said.

"As in the case of power unit 1, which was shut down in December 2018, regular operations will be carried out with the second unit. In fact, the procedures performed practically do not differ from ordinary maintenance," Vladimir Pereguda, director of Leningrad NPP said. "Now our task is also to service reliably and safely the shutdown units, unload nuclear fuel from the reactors and prepare them for transfer to the specially created enterprise Experimental Demonstration Engineering Centre."

Noting the start-up of Leningrad II-2, Andrey Petrov, the general director of Rosatom's operator subsidiary Rosenergoatom, said: "The replacement of the retired capacities will be imperceptible to electricity consumers."

Compared to RBMK power units, the new VVER-1200 power units that are being commissioned have a number of advantages, Rosatom said. They are 20% more powerful, and the service life of their irreplaceable equipment is doubled, to up to 60 years. ... rad-2-RBMK

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. ... -fuel-cycl

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.

The Beloyarsk 3 BN-600 (Image: Rosenergoatom)

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. ... until-2025

La centrale nucléaire Leningrad II commence à fournir de la chaleur au réseau de chaleur de Sosnovy Bor.
Ça prend le relais de ce qui était fournit par le réacteur RBMK-1000 mis à l'arrêt l'an dernier.
Leningrad II plant begins providing district heating

02 December 2019

Unit 1 of Russia's Leningrad II nuclear power plant has been integrated into the heat supply system of the city of Sosnovy Bor, operator Rosenergoatom has announced. The VVER-1200 reactor will replace electricity and heating capacity lost with the closure last December of the first of four RBMK-1000 units at the nearby Leningrad plant.

All major manufacturing and production companies located on the industrial park in Sosnovy Bor were the first to receive the heat produced by Leningrad II-1, Rosenergoatom said. The next stage will be to integrate the reactor's heat supply into the city's residential heating system.

The net cost of heat generated at the Leningrad nuclear plant is far lower than that produced by boiler rooms run on organic fuel, the company said. In addition, the use of nuclear-generated heat avoids the emission of carbon dioxide and has a lesser impact on the environment.

"The VVER-1200 power block is a replacement for both electricity and heat capacities, and it will start delivering those as a replacement for the shutdown RBMK-1000 power block," said Dmitry Tsygankov, head of the turbine hall of Leningrad II unit 1. "The Leningrad NPP turbine hall and district heat supply boiler room teams have fully ensured reliable and trouble-free heat supply to the city and the industrial park using a high-capacity power block that can output twice as much as an RBMK block."

Andrey Graf, deputy head of Leningrad II-1's turbine hall, added: "The thermal output of the new power block is 3200 MW or 250 Gcal/h, which is pretty much enough to supply heat to the industrial park and all Sosnovy Bor. As of now, we are only using one-third of the equipment's capacity, and it caters for 60% of the boiler room's heat demand. In the future, we are ready to fully load our cogeneration plant and start selling heat power for central heating and hot water supply in the nuclear power city and satisfy any demand."

The existing Leningrad plant site comprises four RBMK-1000 units, while Leningrad II will have four VVER-1200 units. Leningrad unit 1 was shut down for decommissioning on 21 December last year, with the other three units scheduled to shut by 2025. Leningrad II unit 1 was connected to the grid on 9 March 2018, becoming the second VVER-1200 reactor to start up, following the launch in 2016 of Novovoronezh unit 6. The loading of fuel into the Leningrad II-2 VVER-1200 is scheduled to begin in March next year. ... rict-heati

Russia plans next two nuclear icebreakers

30 October 2019

Atomenergomash, the engineering division of Russia’s Rosatom, has signed a contract for the supply of RITM-200 reactor units for two more nuclear icebreakers in Project 22220. The contract was signed between Atomenergomash subsidiary OKBM Afrikantov and the Baltic Shipyard.

The new vessels will join the LK-60 icebreakers Arktika, Sibir and Ural, which are dual-draught (8.55 or 10.5m) wide-beam (34m) ships of 25,450 dwt or 33,540 dwt with ballast, able to handle 3m of ice. They each have two RITM-200 reactors of 175 MWt each, delivering 60 MW at the propellers via twin turbine-generators and three motors. Arktika is expected to enter operation in 2020, Sibir in 2021 and Ural in 2022.
One fuel load for a RITM-200 unit is equivalent to 540,000 tonnes of Arctic diesel fuel, it said, with fuel reloads required once every seven years. ... cebreakers

Rosatom postpones fast reactor project, report says

13 August 2019

Rosenergoatom is expected to receive about RUB280 billion (USD4 billion) less in state funding for the construction of new nuclear reactors in Russia owing to the postponement of its fast neutron reactor programme, Russian newspaper Kommersant reported last week, citing anonymous sources. Rosenergoatom is the nuclear power plant operator subsidiary of Russian state nuclear corporation Rosatom.

Rosatom's investment plan received preliminary approval during a meeting in the Russian Energy Ministry on 2 August, according to the article, with funding out to 2035 to total RUB880 billion and not the RUB1.16 trillion Rosatom had allocated for the two new VVER-1200 units under construction for the Kursk II project, units 3 and 4 for the Leningrad II project and a BN-1200 fast reactor at Beloyarsk. Commissioning of the BN-1200 has been postponed to 2036, the article said, from the previous target of 2027.
A Russian government decree published in August 2016 indicated the country planned to construct 11 new nuclear power reactors by 2030 - including two BN-1200 sodium-cooled fast neutron reactors. The BN-1200 units are to be built at the Beloyarsk and South Urals nuclear power plants. The BN-800 fast neutron reactor - constructed as unit 4 of the Beloyarsk plant in the Sverdlovsk district - entered commercial operation in October 2016. The 789 MWe unit's capacity exceeds that of the world's second most powerful fast reactor - the 560 MWe BN-600 Beloyarsk 3. The planned Beloyarsk 5 BN-1200 will use larger fuel elements than the BN-600 and BN-800 and have a simplified refuelling procedure. Russian nuclear engineering company OKBM Afrikantov is developing the BN-1200 as a next step towards future reactor designs, commonly known as Generation IV.

According to the Kommersant article, the capex of the BN-800 amounted to RUB140.6 billion. ... report-say

Sur les traces d'un mystérieux nuage radioactif russe
Nathan Mann, publié le 30/07/2019 l'express

La présence de ruthénium radioactif dans l'air européen en 2017 proviendrait de l'usine de retraitement du combustible nucléaire russe de Maïak. Récit.

Les chercheurs du "ring of five", un réseau informel reliant les stations européennes de surveillance des matériaux radioactifs dans l'atmosphère se sont livrés à un véritable jeu de piste presque deux ans après les faits. En octobre 2017, un panache de ruthénium 106 - un élément radioactif qui n'avait pas été repéré dans l'atmosphère depuis la catastrophe de Tchernobyl - est détecté au-dessus du Vieux Continent. A l'époque, si les taux étaient trop faibles pour mettre en danger la santé des habitants survolés par ce nuage radioactif, l'origine du ruthénium n'en demeurait pas moins mystérieuse puisque aucune installation nucléaire avait déclaré d'incident.

L'enquête, signée par 69 scientifiques de différents instituts européens et dont les résultats ont été publiés dans les comptes rendus de l'Académie des sciences américaine (PNAS) le 29 juillet 2019, corrobore les premières suppositions des experts. La fuite proviendrait de l'usine de retraitement de combustibles nucléaires de Maïak, dans le sud de l'Oural russe. Au conditionnel toujours, car les chercheurs ne relèvent qu'un faisceau d'indices, et que les autorités russes ont nié dès 2017 tout accident sur ce site. (abonnés) ... 92279.html

Russie lance le brise-glace nucléaire Ural ROSATOM

Publié le 27/05/2019 par Vincent Groizeleau

L’Ural, troisième des nouveaux brise-glaces russes à propulsion nucléaire du projet 22220 (classe LK-60Ya), dont deux autres unités seront commandées cet été, a été lancé le 25 mai à Saint-Pétersbourg, où ses deux aînés sont en achèvement à flot. Ces navires de 173 mètres de long pour 34 mètres de large et 10.5 mètres de tirant d’eau afficheront un déplacement de plus de 33.000 tonnes en charge. Ils pourront briser une épaisseur de glace allant jusqu’à 3 mètres. Dotés de trois lignes d'arbres, avec une puissance propulsive de 60 MW, les LK-60Ya sont équipés de deux nouveaux réacteurs nucléaires RITM-200, qui seront également employés sur les centrales flottantes développées par Rosatom. Ces réacteurs peuvent générer une puissance unitaire de 175 MW. « Une autre caractéristique unique des navires du projet 22220 est sa conception à double tirant d'eau. Les citernes de ballast à l'intérieur de la coque peuvent être facilement ajustées pour modifier le tirant d'eau du navire selon qu’il doit naviguer dans la mer Arctique ou dans les estuaires peu profonds des rivières. Avec cette solution intelligente, Rosatom obtient deux types de brise-glace pour le prix d'un, ce qui représente une économie potentielle de centaines de millions de dollars », explique le groupe russe.
