Saying this while nuclear power depends greatly on Russia and no country could sanction Rosatom shows how grounded in reality these discussions are.
- Russia mines 5% of the world's Uranium.
https://en.wikipedia.org/wiki/Uranium_mining
- The reason we only use less than 5% of the Uranium fuel, so throwing away 95%, is that the fuel is so cheap (= abundant) that it is cheaper to just throw it away
- Fuel costs are basically a negligible component of the lifecycle costs of a nuclear reactor

"at worst, some long-term Russian supply contracts could not be executed, and that would perhaps raise the price of electricity 1 or 2 percent."
World-ending.
Also, it's an US-centric article and as it's states, the US only has a 15% dependency on Russia. So you are already looking at a very favorable outlier that makes the situation look better than it actually is. Most other countries have a much greater dependency.
But it certainly in no way supports your claims.
¯\_(ツ)_/¯
