The Energy Company Uniper is the owner of Sydkraft Nuclear Power, Sweden. Uniper is
responsible for decommissioning of the two Barsebäck nuclear power units B1
& B2 located across from Copenhagen on the west coast of Sweden, as well as
for the Oskarshamn units O1 & O2 situated on the Swedish east coast.  

Barsebäck unit B1 closed in 1999 and unit B2 in 2005, while Oskarshamn O2 closed in 2015 (after 2,5 years of outage), and unit O1 in 2017. O1 was the first commercial
NPP in Sweden and the smallest of the four. B1, B2, and O2 are triplets,
meaning that their design is almost identical. 

Oskarshamn unit O3 is still in operation with a planned end of life in 2045. 

A strategy work performed in 2017-2018 was a unique endeavor as it evaluated various
scenarios for the decommissioning of the four units. The chosen one was to
combine all four units in an integrated fleet approach, a strategy that was
both innovative and proved very efficient. 

This selected scenario, known as the Sequence Scenario, was designed to
tackle the critical and more complex work packages in a full combined sequence
for all 4 units, ensuring a smooth and systematic process. This IDA event will
go into detail as to how, why, and what lessons were learned, as well as how
recycling and resource management were implemented and executed from the start. 

The scheduled total duration for the radiological dismantling work and the planned free
release of the sites is a testament to the strategy's effectiveness, namely totaling
10 years – making this unique for nuclear power plant dismantling globally.

In combination with the pragmatic Nordic regulatory framework, this fleet approach
has enabled the D&D program to aim to be THE international benchmark for
cost- and exposure-efficient dismantling.

At this event, we will present and discuss the actual results of our fleet approach, the lead and learn approach, our main learnings, the achieved results, and successes so far as well as show and discuss key factors and our leading KPIs demonstrating the positive impact this lead & learn approach led to.


After the presentation, there will be sandwiches, soda, beer, and coffee.
