A delegation of representatives of the Utility Management Board headed by Acting President of NNEGC “Energoatom” Petro Kotin arrived at Zaporizhzhya NPP on a working visit.
The program of the visit is varied and includes all important activities of Zaporizhzhia NPP, and all the facilities of the plant to be visited are closely combined into one ultimate goal – improvement of safety and reliability of both Zaporizhzhia NPP and the united power grid of Ukraine.
The visit began with attendance at the Zaporizhzhia NPP dry spent fuel storage.
Until recently, only Zaporizhzhia NPP was able to store spent nuclear fuel in Ukraine and not pay hundreds of millions of dollars for temporary storage to other countries. Thanks to the Zaporizhzhya NPP Dry Spent Fuel Storage, which has been safely operated for two decades, experience has been gained and the technology of spent fuel dry storage of has been tested.
And now, with the completion of the construction of the first start-up facility of the Centralized Spent Fuel Storage Complex, after testing the equipment and systems and obtaining the necessary permits and licenses, NNEGC “Energoatom” will be able to store spent fuel from three other Ukrainian NPPs (South Ukraine, Khmelnytsky and Rivne) in the Centralized Storage Facility.
“Completion of construction of the Centralized Spent Fuel Storage Complex is a step towards true energy independence, as the domestic nuclear power industry will finally lose its dependence on Russian spent fuel reprocessing and storage facilities, and the Utility will be able to save significant funds, which will reduce its own electricity costs,” the Utility Head said.
After the Dry Spent Fuel Storage, the delegation visited the ZNPP Unit 5 and the central control room of the plant shift supervisors.
At Unit 5 the scheduled interim overhaul is coming to an end. During it scheduled and over-scheduled activities target at improving the safety of the power unit have been performed. At the final stage the extension of service life is planned. An inspection of the SNRCU is currently underway to verify the status of implementation of the necessary measures, which will allow a decision to be made on the possibility of continuing the operation of the power unit. All activities are performed according to schedule. So, as early as in January all six power units of Zaporizhzhia NPP will be in operation.
The central control room of the plant shift supervisors is a modern complex of industrial and domestic compartments, with all life support systems, equipped with new equipment and communications that allow you to quickly perform all production tasks, was commissioned in 2014.
Over the years of operation, all means of control and monitoring of the central control room have proved to be the best. And the area of the central control room allowed placing also the experts of the commercial dispatching department after its creation.
The Utility specialists also paid attention to personnel training, by monitoring and evaluating the process of conducting emergency training for operating personnel on the control room full-scope simulator.
The next and most important facility of the current visit was 750 kV switchyard, on which the delegation led by Acting President of the Utility Petro Kotin took part in the ceremonial events on the occasion of the completion of the construction of the overhead power line Zaporizhzhia NPP – “Kakhovka” substation.
“A very important event took place - the 750 kV Zaporizhzhia NPP power line - “Kakhovka” substation - was put into operation. For the first time, Zaporizhzhia NPP has no grid restrictions - for the first time in the history of Zaporizhzhia NPP, the plant can operate six units and supply all 6000 MW to the power grid. Having received this fourth main line, we have significantly increased the reliability of electricity supply by Zaporizhzhia NPP, significantly increased the reliability of the entire load center,” - said Acting President of NNEGC “Energoatom” Petro Kotin during the solemn events.
This large-scale investment project, the implementation of which was the result of joint efforts of NNEGC “Energoatom” and NEC “Ukrenergo”, will significantly increase the reliability of Zaporizhzhia NPP in terms of power output. The six power units of the plant will now operate without any reduction in generation, which was approximately 700 MW per hour and 17 million kWh of electric power per day. These are significant figures for the economy of Ukraine and for the energy industry of the country.
The project was implemented with credit funds from the European Bank for Reconstruction and Development (EBRD) and the European Investment Bank (EIB).
The “Kakhovka” overhead power line will help to redistribute the electric power produced by ZNPP, create opportunities for maneuver without power reduction, and improve the supply for Kherson and Odessa regions.
In the future, the overhead power line Zaporizhzhia NPP – “Kakhovka” substation will be important in synchronizing the Ukrainian grid with the European one.
