Rosenergoatom: Akademik Lomonosov FNPP has completed one of the key operations of the year - both turbines have been put on the turning gear

In St. Petersburg, one of the most important stages in the preparation for operating Akademik Lomonosov FNPP, the world's only floating nuclear power plant – putting the power unit (FPU) turbine on the turning gear – has been completed.

Successful completion of this operation confirms that the installation of both turbines was completed correctly and the equipment is fully operational.

On 19 December, 2017, the specialists of Baltiyskiy Zavod - Sudostroyeniye LLC (BZS LLC) that conducts scheduled mooring tests at the facility carried out the turning of the rotor gear of the second steam-turbine plant of the portside. A few days earlier the same technological operation was carried out on the starboard of the vessel.

It followed the standard scheme - started at the rotor turning gear, which is driven by the electric motor and rotates the rotor at a speed of 7 revolutions per minute. The main purpose of the turning gear is to prevent the thermal deflection of the turbine rotors during its start-up and shutdown periods.

As far back as at the stage of preparation for turning the turbine generator had undergone a whole range of technical works to ensure the readiness of the auxiliary turbine systems’ mechanical and electrical equipment.

According to the Deputy Head of the Directorate on Construction and Operation of the floating NPP Dmitriy Alekseenko, the putting on the turning gear was successful, without comments. “The specialists carefully checked the correctness of assembling and aligning all the elements of the turbines’ flowing part, as well as their axes compliance with the turbine generator gear. No interference was observed during the rotation of the STP rotors. Both turbines are assembled in accordance with the current rules and regulations”, he said.

In turn, the Head of the Directorate on Construction and Operation of the floating NPP Vitaliy Trutnev emphasized, “The putting of both turbines of the FPU on the turning gear demonstrates its high technical readiness for operation. This is an important event for us; it completed a large complex of works connected with the assembly of all elements of the two turbines and FPU generators. And the great merit in their successful completion belongs to highly qualified specialists of both BZS LLC and Kaluga Turbine Plant, who took a direct part in carrying out these tests.”

It is planned to continue testing the FPU systems and equipment at design parameters till the end of 2017. After they are completed and the work to prepare the FPU for transportation is done, it will be towed to Murmansk on the site of Atomflot FGUP in the spring of 2018. In autumn 2018 the nuclear fuel will be loaded into the reactor and the FPU will be physically start-up.

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.
