Electricity producer ČEZ said Thursday that the unscheduled shutdown of
its Dukovany-4 nuclear reactor had ended early in the morning.
The 510 MW capacity reactor should be at full power during the evening of November 23. That would mean all four Dukovany reactor and two Temelín reactors would be operating normally.
The unscheduled outage began November 8 following a leakage of non-radioactive water outside the core reactor area.
The same day as the unscheduled outage started, CEZ had announced it expected output from its two nuclear plants, Dukovany and Temelín, to rise to 8.0 TWh in the last quarter.
Dominant Czech electricity producer and nuclear power plant operator ČEZ
said Thursday that a small leak had been found in a measuring pipe in the
non-radioactive part of the Dukovany-4 reactor.
The repairs will take several days, the company added. The rector was powered down late Tuesday with no electricity being supplied to the network several hours later.
CEZ has insisted that radioactive water is not involved. All ČEZ’s other reactors at Dukovany and Temelín are functioning normally.
The nuclear power plant in Dukovany is fully operational once again, after
undergoing maintenance on its third reactor, which was out of operation for
a period of four months. It was reconnected to the power grid on Friday.
The reactor underwent a change of fuel, a maintenance check and minor repair-work. The reactor should be producing at full capacity by Monday.
The Czech power utility ČEZ is selling its coal-fired power plant in Varna
to the Bulgarian company SIGDA OOD. ČEZ was forced to halt operations at
the plant in 2015 after it failed to bring it up to EU environmental rules.
ČEZ said it had been denied an exemption by the European Commission and
the plant could not continue to work without an environmental upgrade. With
a generating capacity of 1,260 megawatt, the plant serves as a back-up to
the national power grid and the Bulgarian authorities have stressed the
importance of keeping it in operation, pointing out it could become a much
needed source of energy if Bulgaria were to be hit by a gas crisis.
ČEZ wants to leave the Bulgarian market due to drawn-out problems with the local authorities. It is to decide about the sale of all its Bulgarian assets, which include two renewable energy plants and an electricity trader, by the end of this year.
The lower house has refused to lift a ban on deliveries to the Iranian
nuclear plant in Bushehr, in line with a proposal tabled by the Communist
The law enforcing such a ban was passed in 2,000 in reaction to a Czech firm’s plans to deliver ventilation equipment for the plant.
The deal was criticized by Britain and the US amid growing suspicion that Iran was using civilian nuclear program to cover up its nuclear projects in the military.
An agreement has since been reached with Iran which resulted in the lifting of sanctions against the country in the nuclear sphere, but the majority of Czech MPs still voted against lifting the ban, expressing concern with regard to Iran’s nuclear program and arguing that such a move could damage the country’s close ties with Israel.
The Czech Republic and Jordan on Tuesday agreed to cooperate in a peaceful development of nuclear energy. The agreement was signed on Monday during a visit of Jordan’s Prime Minister Hani Mulki to Prague. According to Czech Prime Minister Bohuslav Sobotka, it will enable better cooperation in science and research and allow Czech firms to participate on construction of nuclear reactors in Jordan. During their meeting, the Czech and Jordanian prime ministers have also discussed humanitarian aid, trade and problems in the Middle East.
