The Kozloduy Nuclear Power Plant in Bulgaria has announced the temporary shutdown of Unit 6 to facilitate the replacement of a damaged safety component in its turbine system. The specific part being replaced is a rupture membrane assembly located within the moisture separator reheater, which is part of the plant’s conventional non-nuclear infrastructure.
According to plant operators, this issue is confined solely to the turbine island, and they have confirmed that it has not resulted in any environmental impact or pollutant release. The new rupture membrane and pin have been fabricated from recently sourced materials that adhere to the original technical specifications. Once maintenance activities are completed, Unit 6 is anticipated to be reconnected to the national power grid.
Meanwhile, operations at Unit 5 remain unaffected as it continues to function efficiently and achieve its production goals. This maintenance intervention on Unit 6 is not unprecedented; a similar issue with the turbine’s rupture disk assembly had previously necessitated an offline period late last year before it was successfully restarted.
