Temelín started to reduce its output in a planned manner and will initiate a two-month shutdown for refuelling on Friday night.

Tonight, Temelin Unit 1 began to reduce its power slowly. Operators will shut down the Unit for scheduled equipment checks and refuelling on Friday evening. During the outage, technicians will conduct 82 dozens of investment actions related to the plant's modernization. In total, ČEZ has nearly 16,000 activities planned for approximately two months during the outage.

Reducing power three days in advance is a signal of reliable operation.

"The so-called power effect operation we are moving to results from the previously safe and reliable operation. The lower power output will allow us to "draw" more energy from the fuel assemblies and thus use them as efficiently as possible,"

said Jan Kruml, Director of the Temelín Nuclear Power Plant.

The power plant's shutdown is planned for Friday night and will occur at approximately one-third of the reactor rated power. According to the power plant management, this will be a standard outage associated with essential checks and investment activities. "Important works will also include inspections of safety divisions, steam generators, main circulation pump or replacement of 42 of 163 fuel assemblies," said Jan Kruml.

"Outages of nuclear units are the most demanding period of the year; we must coordinate thousands of activities in a limited time space. The works run 24 hours a day, but the emphasis on safety and quality is absolutely crucial,"

says Bohdan Zronek, member of the ČEZ Board of Directors and Director of the Nuclear Energy Division.

Including the external suppliers, around a thousand people participate in the outage works. It is the first planned outage at Temelín this year, and the two-month outage of Unit 2 will begin in the second half of August.

Unit 1 has been in continuous operation since May 22 last year. Unit 1 produced over 8,5 million MWh of emission-free electricity in almost eleven months.



Since the beginning of the year, the Temelín power plant has produced 4.9 terawatt hours of electricity. Together with Dukovany, these sources make the most considerable amount of clean electricity and thus contribute significantly to ČEZ Group's emission-free production. Annually, approximately two ten million tons of CO2 have not been released into the atmosphere thanks to nuclear power plants.
