On the 25th of May the turbine was set for barring in the turbine hall of Unit 4 at Rostov NPP. This is one of most important stages of pre-commissioning. “The turbine has been set for barring and this demonstrates high technical availability of the turbine set and its auxiliary systems for hot and cold runs of the reactor,” Vice President for Projects in Russia of Group of Companies ASE Alexei Deriy said. “This stage completion is one more step to ensure timely first power of the unit,” he said. The main purpose of the process operation was to check on correctness of assembling and alignment of all components of the turbine’s through section as well as alignment of its axes with the turbine generator’s shaft. First power of the unit is set for the end of 2017.
