Rosenergoatom: at the floating power unit of Akademik Lomonosov FNPP one of the two turbines was put on the turning gear

In the turbine island of Akademik Lomonosov floating nuclear power plant (FNPP) one of the two turbines of power unit (FPU) was put on the turning gear.

Recently the specialists of Baltiyskiy Zavod – Sudostroyeniye LLC (St. Petersburg) - where the scheduled mooring tests of the facility are carried out - have successfully performed the operation on rotor spinning of steam-turbine plant (STP) of starboard with the speed of 7 rpm. This was necessary in order to prove that turbine is assembled in accordance with the up-to-date rules and norms.

The putting of the turbine on turning gear is one of the most important stages of the FPU preparation for operation. The main purpose of this technological operation is to check the assembly accuracy and alignment all elements of wheel space, as well as compliance of its axes with the turbine generator gear.

At the stage of turbine generator preparation for putting on the turning gear the specialists carried out a number of technical works that provide the readiness of the mechanical and electrical equipment of the turbine auxiliary systems, in particular of the oil supply systems.

The putting of the first turbine on the turning gear shows the high technical readiness of the turbine generator and its auxiliary systems for the further mooring tests execution.

By the end of this year it is planned to carry out the same operation with the second steam-turbine plant of the FPU of the floating nuclear power plant. Then, the FPU system and equipment tests at the design parameters will be continued.

After the completion of all mooring tests and execution of works on the FPU preparation for transportation it will be hauled to Murmansk at the site of Atomflot FGUP in spring 2018. And in autumn 2018 the nuclear fuel will be loaded into the reactor and the FPU will be physically launched.

The Rosenergoaton Concern (the power division of the Rosatom State Corporation) includes 10 Russian nuclear power stations bearing the status of the Concern’s affiliate companies, along with the vendors catering for the needs of the generation company. All in all, the 10 nuclear power stations operate 35 power blocks* (*excluding the Novovoronezh NPP’s 6th power block being at the pilot production stage): 18 of them operate VVER reactors (12 VVER-1000 power blocks and 5 VVER-440 power blocks of different modifications); 15 of them with channel reactors (11 power blocks with RMBK-1000 reactors, four power blocks with EGP-6 reactors); and 2 power blocks with fast neutron sodium cooling reactors (BN-600 and BN-800).

At the moment, the Rosenergoatom NPPs account for 18.3% of the whole electricity output in the

country.

The floating power unit (FPU) Akademik Lomonosov of 20870 project is designed for the operation as a part of the Floating Nuclear Power Plant (FNPP). The time-proved technologies of marine (icebreaker) reactor plants are the basis of the project. The FPU has 2 steam-generation units with KLT-40S reactors with the capacity of 35 MW. This main project of the serial mobile movable low-powered power units for supply of the energy to the large industrial enterprises, port cities, complexes for the oil and gas extraction and processing at the sea shelf is created on the basis of the serial power plant system of nuclear icebreakers proved during the long period operation in Arctic.

The FNPP is designed with the greater safety margin that makes nuclear reactors invincible for tsunami and other natural disasters. In addition the nuclear processes at the ships correspond to all the requirements of the International Atomic Energy Agency (IAEA) and do not harm the environment.
