State-owned enterprise National Nuclear Generating Company Energoatom and JSC Turboatom (Kharkiv) signed the five year (2020-2024) program on modernizing equipment of Ukrainian nuclear power plants (NPPs) on Tuesday.
According to a press release of Energoatom, the program involves the replacement of eight turbine condensers of nuclear power reactors, including four Russian-made condensers. After replacing the condensers, the total increase in power of reactors will be about 400 MW.
The document also provides for the modernization of flowing parts of turbine cylinders with a capacity of 200 MW and 1000 MW, including five turbines with a capacity of 1000 MW as part of import substitution. Modernization includes the replacement of rotor blades on existing rotors and diaphragms, which will increase the turbine’s power and its efficiency.
It is also planned to upgrade the high-pressure cylinders of the turbines of the Zaporizhia NPP, starting in 2020. Modernization of turbines will increase the capacity and efficiency of existing reactors of Ukrainian NPPs by 10%, which will provide a power increase of 70-100 MW at each reactor.
In addition, on Tuesday in Enerhodar (Zaporizhia region), an agreement was signed between Atomkomplekt (a separate division of Energoatom) and Turboatom for the manufacture and supply of a block-modular condenser for replacing the condenser of the K K-1000-60/1500 turbine at reactor five of Zaporizhia NPP in April 2020.
The parties also discussed a long-term repair program for the replacement of used spare parts.
“Four years ago, we gave a new powerful start to our cooperation, which is not only servicing the turbine park, but also the replacement and modernization of equipment. This will allow us to increase and improve the efficiency of nuclear power plants, to increase the generation of electric energy, which is important in conditions a new market, when every additional kilowatt-hour produced gives additional income,” Energoatom President Yuriy Nedashkovsky said.
According to the CEO of Turboatom Victor Subbotin, the volume of modernization at Energoatom for five years will exceed UAH 6 billion, which is a significant contribution to the utilization of production capacities and personnel of the enterprise.
State-owned enterprise Energoatom in January-June 2018 saw net profit rise by almost 2 times compared to the same period last year, to UAH 3.186 billion. According to reporting on the website of the generating company, its net income in the first half of the year increased by 1.1%, to UAH 20.747 billion, while gross profit decreased by 1.8%, to UAH 5.166 billion.
As reported, Energoatom in 2017 received a net loss of UAH 1.322 billion against UAH 232.791 million of net profit for 2016. Net income in 2017 increased by 6.7%, to UAH 38.488 billion, while gross profit decreased by 16.7%, to UAH 4.773 billion.
Energoatom is the operator of all four operating NPPs in Ukraine. It operates 15 power units equipped with VVER reactors with a total installed capacity of 13.835 GW.
National Nuclear Generating Company Energoatom has signed a contract with Orano (earlier Areva, France) to assess the possibility of the practical implementation of services to reprocess spent nuclear fuel assemblies from Ukrainian reactors of VVER-1000 type at the French La Hague Reprocessing Plant. “This contract marks an important step for Orano. It is a real success for us. It will pave a way for treating Ukrainian spent nuclear fuel by the French reprocessing sector,” the press service of Energoatom reported, citing Senior Executive Vice President of Orano’s Recycling Business Unit Pascal Aubret.
Energoatom said that after producing electricity in a power reactor, the spent fuel contains 96% of recyclable materials and 4% of final waste. The process implemented at Orano’s La Hague plant separates the reusable materials, which will once again be used to produce energy, from the final waste which undergoes safe and stable conditioning and packaging.
According to an announcement of Energoatom in the ProZorro e-procurement system, the cost of the contract signed with Orano Cycle is EUR 1.395 million. The company is to finish the study before December 31, 2020.
At present, Energoatom sends spent nuclear fuel for reprocessing to the Russian Federation. At the same time, there is the problem of handling VVER-1000 spent fuel from Westinghouse. So, while carrying out research on the possibility of processing Westinghouse spent nuclear fuel, information about the design of fuel assemblies is used. Westinghouse agreed to provide relevant information only to Areva.
