Construction sites. Horizontal moisture separator reheaters (MSRs) were installed at Unit 1 of Turkey’s Akkuyu Nuclear Power Plant. They are part of auxiliary systems of the plant’s steam turbine. The MSRs serve to maintain the temperature and humidity of steam that rotates the turbine blades. Horizontal MSRs, which used to be made vertical, were designed specially for the Akkuyu NPP. The improved modification made it possible to put two conventional MSRs into a single body, thus reducing their total number from four to two. In addition, the horizontal design requires almost half as much steel as conventional MSRs while being more efficient, reliable and cost-effective in general. Rosatom is building four power units with VVER-1200 reactors in Turkey.

Shipments. Rosatom manufactured high- and low-pressure wedge gate and swing check valves for the Rooppur NPP and shipped them to Bangladesh. The shipment includes 294 pieces with a total weight of 312 tonnes. The valves will be used in the reactor buildings and turbine halls of Rooppur Unit 1 and 2. The products are designed to withstand high loads, including pressure up to 12 MPa and temperature of about 300°C. The valves belong to safety classes 2, 3 and 4. Before shipment, they passed a series of factory trials, including pneumatic, hydraulic and vacuum pressure tests. The Rooppur NPP is being constructed 160 km away from Bangladesh’s capital Dhaka. The plant will have two Russian-designed VVER-1200 reactors with a total capacity of 2,400 MW.

Cooperation. Rosatom will present its advanced nuclear power solutions at the 8th Russia-China Expo to be held in Harbin in late May. The event is timed to coincide with the 75th anniversary of the establishment of diplomatic relations between Russia and China. Rosatom’s booth will feature solutions for large and small-scale nuclear generation, floating nuclear power plants, fast neutron reactors, wind generation, nuclear medicine, and other applications. The key areas of cooperation between Rosatom and China include the construction of power reactors, nuclear fuel supplies to China, development of fast neutron technology, and solutions for the closed nuclear fuel cycle. Rosatom is involved in the construction of four Russian-designed power units with VVER-1200 reactors in China, two at Xudabao and two at Tianwan.
