Beznau nuclear power plant: Unit 1 back on grid after scheduled outage

22.05.2020 – The Beznau nuclear power plant (KKB) has completed refurbishment work on Unit 1 and reconnected the reactor to the grid today following the approval of the Swiss Federal Nuclear Safety Inspectorate (ENSI). It was possible to complete the work on schedule despite all the corona-related restrictions and additional efforts. 

The focus of refurbishment comprised maintenance work, recurring tests and inspections. In addition, integral system tests were carried out as usual. Of the 121 fuel assemblies, 20 were replaced with new elements and installed in the reactor core.

As usual during a restart, KKB will also conduct various, additional safety tests on Unit 1 and gradually take up full-load operation. The plant will be back to full load in three days.

During refurbishment the approx. 460 employees at KKB were supported by some 400 external specialists from the region, as well as from Switzerland and abroad. KKB implemented strict measures to prevent the spread of the corona-virus and to protect its own and external staff. Entrance checkpoints, strict adherence to hygiene and distancing rules, health check-ups, quarantine in suspected cases, split operation and home office proved to be effective. No corona-virus infections occurred.

At times, visible steam will be emitted from the non-nuclear section of the plant during the restart. This does not pose any danger to human beings or the environment.

All work was supervised by the Federal Nuclear Safety Inspectorate ENSI.

Strong operating performance – but earnings blunted by financial markets

The Axpo Group’s half-year financial results for 2019/20 (1 October 2019 to 31 March 2020) were influenced by two factors: a strong operating performance, which was up once again on the prior-year period, and the negative impact of volatility on the financial markets. The funds for the decommissioning and disposal of nuclear power plants (STENFO) had a particularly significant negative impact on results of CHF 389 million. Whereas earnings before interest and tax (EBIT) were still only slightly lower at CHF 329 million despite the Covid-19 crisis, the result for the period fell to CHF – 24 million.
