In 2024, the cost for storing nuclear waste just up until 2100 was estimated to be 170 Bln. [1]
This cost is always, without exception, excluded in the calculation of the cost of generating a MWh. It's externalized, paid for by the next generations of taxpayers.
Gösgen's open data, just like all the other data, does not include waste management cost.
Gösgen is a perfect example for how brittle and outdated the technology is. The nuclear plant is off the grid since May 2025 and will remain down until at least February 2026 [2]
Just like the newly-built Flamanville 3 (12 years late, 10+Bln over budget), it's off the grid until further notice. [3]
The world is phasing out nuclear.
