OREANDA-NEWS. December 15, 2011. On December 12 Russian Prime Minister Vladimir Putin came to the Kalinin nuclear power plant (KNPP) on a working visit and took part in the events, pertaining to the pilot commissioning of the fourth energy block of the plant.

 In 2007, Stroytransgaz started the construction of the fourth energy block of KNPP while being the main contractor for the construction of the main building of the energy block and hydro-engineering facilities. The scope of work included the construction of over 20 energy block facilities, among them the reactor compartment, the cooling tower, the power house and the water culverts. To carry out the project, Stroytransgaz mobilized over 1,000 specialists of 19 different areas of expertise. The implemented construction works had the first category of difficulty. 

 Stroytransgaz established the production branch in Udomlya and invested 300 million RUR in the property, plant and equipment, including the purchase of unique tower crane KROLL-К10000 with two crane arms, 146 meters high and lifting capacity up to 240 tons, which considerably reduced the time of the energy block construction.

 Background:
 Stroytransgaz is a major Russian construction and engineering company. It implements and manages investment and construction projects in oil and gas, power energy and other fields of industrial and civil construction. The company carries out power energy projects constructing cogeneration plants and nuclear power stations as well as electric grid facilities that make over 50% share of the company's revenue structure.

 The Kalinin nuclear power plant is located in Udomlya Rayon of Tver Oblast and provides all the central territories of Russia with power energy. In 1991, the construction of the fourth energy block was suspended and was not renewed until 2007 after the federal target program Development of the Nuclear Energy Industry of Russia for 2007–2010 and the Future to 2015 was approved. The Federal Agency for Atomic Energy is customer for the project. Its general contractor is the federal governmental enterprise NIAEP. The reactor model is В-320 (modification ВВЭР-1000). Energy generating capacity of the facility is 1,000 MW and heating power – 3,000 МW.
