JSC Turboatom (Kharkiv) in April plans to deliver a first modernized rotor under a contract to modernize high- and medium-press cylinders of reactor two of Yuzhnoukrainsk nuclear power plant for the total amount of UAH 300 million.
According to a report on Turboatom’s website, the contract was signed on February 25 by Turboatom Director General Viktor Subotin and Director of the Atomkomplekt division of National Nuclear Generating Company Energoatom Ruslan Zhmudsky.
According to Subotin, the signed agreement is the first contract to modernize the flow section of this type of turbine in Ukraine. The company has already performed similar work for customers outside the country, including at reactor five of Kozloduy NPP (Bulgaria).
“An entire program to modernize the flow sections of the reactors of Ukraine, both of our turbines and of Russian ones, is ahead,” the press service said, citing Subotin.
In turn, Zhmudsky said that the signed contract is part of the approved five-year modernization program.
“The program is designed until 2024, and in the situation that has developed now (namely, lack of funding for the construction of new reactors), the modernization of existing equipment will give us up to 10% of additional capacity,” he said.
According to Deputy Director General of Yuzhnoukrainsk NPP Andriy Petruk, the plant has been using Turboatom’s equipment for many years.
“The most important thing for us is the import substitution program, with which Turboatom helps us. The modernization, the contract for which has been signed, will increase the electric power by approximately 100 MW,” he said.
According to Turboatom General Designer Yevhen Levchenko, the five-year program provides for the modernization of seven more of the same reactors: one at Yuzhnoukrainsk NPP and six at Zaporizhia NPP.
“The next step is the modernization not of our turbines, but of the turbines manufactured by Russia’s Power Machines,” he added.
The Rivne nuclear power plant on July 18 reduced the output of its power unit No.1 (VVER-440) to 50%, having disconnected the TG-2 turbo generator at 05:26 a.m. Kyiv time on Thursday, July 18, after the leakiness of the condensate electric pump line of a turbine unit had been revealed, National Nuclear Energy Generating Company Energoatom’s press service said.
The causes of the incident are being checked. The TG-2 turbo generator is to be put into operation before 02:00 p.m. on the same day.
Energoatom said the incident is rated as “zero,” according to the INES nuclear event assessment scale, or “out-of-scale.”
Thus, as of Thursday morning, 10 of the 15 power units of four operating Ukrainian nuclear power plants were in operation.
