    Construction sites. In early May, a containment airlock was installed at Unit 1 of Turkey’s Akkuyu Nuclear Power Plant. It is a 14-meter cylinder-shaped chamber with gates on both sides. Since the gates open in sequence, they make the reactor containment airtight. The airlock is intended to bring operation and maintenance equipment inside the reactor building. When the nuclear power plant is in operation, it will be also used to deliver fresh nuclear fuel containers into the reactor containment and remove spent fuel casks. The airlock weighs 260 tonnes and is 7 meters in diameter. The Akkuyu Nuclear Power Plant will have four units with Russian-designed VVER-1200 reactors with a capacity of 1,200 MW each.
    Space. Russia has put another Arktika-M satellite with an on-board control system into operation. Developed at Rosatom’s Mars Experimental Design Bureau, Arktika-M No. 2 is the second spacecraft of the world’s only highly elliptical orbit (HEO) constellation of meteorology and hydrology satellites. The Arktika-M constellation provides round-the-clock monitoring of the Earth’s surface, cloud cover, and seas in the Arctic and adjacent regions. It supplies the Northern Sea Route operator with up-to-date information on the ice conditions and helps choose the safest route. Arktika-M also transmits positioning signals from aircraft and vessels in distress to emergency teams as part of the Cospas-Sarsat international search and rescue system.
    Manufacturing. AEM SpetsStal (part of Rosatom’s power engineering division) commenced with the manufacturing of reactor equipment for Unit 1 of Hungary’s Paks II nuclear power plant. “We are working to ensure that the new power units at Paks will be connected to the grid by the early 2030s. The work is simultaneously underway at the construction site in Hungary and thousands of kilometers away from it, in Saint Petersburg. It is important for us, after the start of casting, to have closely watched the initial stages of production of RPV shells,” Paks II Chairman and CEO Gergely Jákli said during the production commencement ceremony. The shells are essential structural elements of the reactor pressure vessel. They are empty cylinders that are welded together. Rosatom is building two power units with VVER-1200 reactors at the Hungarian Paks II NPP. First concrete for Unit 1 is scheduled to be poured before the year-end.
