Two units at Czech Dukovany plant offline for maintenance, joint outage to last three weeks

As of today, two of the four units at the Dukovany Nuclear Power Plant are operating. Two units are offline for planned maintenance of equipment they share. The first Dukovany unit has not supplied electricity since June 2. The plant’s second unit stopped supplying the transmission grid today at 5:00. Plant spokesperson Jiří Bezděk told the Czech News Agency (ČTK). Energy industry estimates suggest the joint outage should last around three weeks.

Plant management will update the schedule depending on the progress of work and the results of inspections. „The amount of work ahead of us during the three-week overlap of the unit outages is considerable. There are approximately 2,000 work-order tasks in this joint outage,“ said Roman Havlín, director of the Dukovany Nuclear Power Plant.

Energy workers began reducing the output of Dukovany’s second unit on Friday at 19:00. They disconnected the first turbine-generator set at 02:00 and the second three hours later. This unit is expected to be offline for three weeks. The longer outage of the first unit, which also involves replacing part of its fuel, is likely to last until mid-August.
