Adding to my previous comment in #543. Decomissioning and costs.
Sweden shut down Oskarshamn 1 last year. O1 is scheduled to be fully decomissioned in 2026. That project started in 1965, first commercial production in 1972.
https://www.iaea.org/PRIS/CountryStatistics/ReactorDetails.aspx?current=534Energy Availability Factor: 62%.
Only a couple of years back OKG stated that they would run O1 until 2032. Now they say they will run the remaining O3 until 2045?
Estimated costs for decomissioning one reactor is 2 billion SEK.
Estimated total costs for Swedish nuclear decomissioning is 141 billion SEK, and counting.
We still do not have an approved waste solution.
Swedish Nuclear Fuel Management AB (SKB) has applied for constructing:
the existing final repository for short-lived low-level waste (SFR)
an encapsulation plant and a final repository for the spent nuclear fuel.
SKB intends to submit an application to build a final repository for long lasting low and intermediate waste by 2030. Applications are reviewed by the Radiation Safety Authority, which will submit its opinion to the government.
If the applications are approved by the government, SKB estimates that the final repository for spent nuclear fuel will be completed around 2030 and the final repository for long-lived low and intermediate waste around 2045. Until a regular final repository is completed, the nuclear fuel from the discontinued reactors will be stored in the central interim storage for spent nuclear fuel (Clab) in Oskarshamn.
That history is almost as long as O1's:
