DOETTINGEN, Switzerland - The Swiss atomic energy plant Beznau 1 will be shut down for 12 hours on Saturday so two valve seals in the plant's non-nuclear section can be replaced.
The plant's operating company Nordostschweizerische Kraftwerke AG says the interruption will cause a visible collection of steam to be released from the non-nuclear part of the center.
The company says the valve seals from the steam turbine section must be changed because they are no longer airtight.
The plant is located in northeast Switzerland.
