There are some reasons i could think of that should make the tax-payers subsidise nuclear investments. Sweden's competitive advantage during the 1900s was cheap energy. And we have some important industries that rely on it. Steelworks and papermills. If they would have to close down because they can't (unfairly) compete with cheap energy, it may have a big effect on the Swedish economy. It may also be that businesses will not do the same risk/reward calculation as a country/taxpayers. They are simply not optimising for the same thing.
