Leningrad II unit reaches first criticality

Concrete pouring for the foundation slabs for the Akkuyu-2 reactor and turbine buildings has been completed, Akkuyu Nuclear has announced. Unit 2 is one of four reactors under construction at the Akkuyu site, located on the Mediterranean coast in southern Turkey.

More than 17,000 cubic meters (about 600,350 cubic feet) of concrete have been poured into the Akkuyu-2 reactor building’s foundation, The company reported on September 23. The area of the concrete slab is 6,864 square meters (about 73,883 square feet), while its height and depth are 2.6 meters (about 8.5 feet) and over 8 meters (over 26 feet), respectively, according to the company.

The U.S. Department of Commerce and Rosatom on September 12 initialed a draft amendment extend the Agreement Suspending the Antidumping Investigation on Uranium from the Russian Federation, signed in 1992. Rosatom is Russia’s state atomic energy corporation.

Should the amendment receive final approval, it will extend the agreement to 2040.

Unit 5 at the Tianwan nuclear power plant completed its full-power continuous operation assessment on September 8, meeting the conditions for commercial operation, China National Nuclear Corporation reported. The domestically designed ACPR-1000 pressurized water reactor will become CNNC’s 22nd reactor to provide power to China’s electric grid, raising the CNNC fleet’s installed capacity from 19.112 million kilowatts to 20.230 million, according to the company.

Tianwan-5 construction officially commenced on December 27, 2015, with the pouring of safety-related concrete. China’s National Nuclear Safety Administration issued a 40-year operating license for the unit on July 7 of this year, and two days later CNNC announced that first fuel loading had been completed. The reactor achieved initial criticality on July 27 and connected to the grid on August 8. Once commercial operation of the unit has begun, Tianwan will boast five operating reactors.

Fuel loading has commenced at Unit 1 of the Belarusian nuclear power plant, according to Rosatom, Russia’s state-owned nuclear energy corporation. The first fuel assembly was loaded into the unit at 11:45 a.m. (local time) on August 7, the company said, adding that a total of 163 assemblies will have been loaded by month’s end.

The plant, Belarus’s only nuclear power facility, houses two 1,109-MWe VVER-1200 pressurized water reactors. Unit 1 is scheduled to begin commercial operation later this year, with a Unit 2 startup slated for 2021.

The first of 163 nuclear fuel assemblies has been loaded into Leningrad II-2, marking the beginning of the Generation III+ unit’s physical startup, Rosenergoatom announced on July 19.

The electric power division of Rosatom, Russia’s state-owned atomic energy corporation, Rosenergoatom is the operator of all of Russia’s nuclear power plants. The fuel for Leningrad II-2, a 1,085-MWe VVER-1200 pressurized water reactor, was manufactured at the Novosibirsk Chemical Concentrates Plant, part of Rosatom subsidiary TVEL.

Preparations have begun for the construction of four nuclear reactors in Russia—two VVER-1200 units at the Leningrad plant and two VVER-TOI units near the Smolensk plant, according to Rosenergoatom, a division of Russia’s state-owned atomic energy corporation Rosatom.

Rosenergoatom operates all of Russia’s nuclear power facilities. Authorization to move forward with the new-build projects was signed by Alexey Likhachev, Rosatom’s director general.

Rosatom, Russia’s state-owned atomic energy corporation, announced on June 18 that it has teamed up with France’s Framatome and General Electric’s GE Steam Power to participate in a tender to construct the Belene nuclear plant in northern Bulgaria. The Belene project would involve the construction of two AES-92 units, similar to the reactors that Rosatom supplied to India.
