A better solution is to adopt sane regulations which allow the plant to be built much more quickly which in turn dramatically reduces the total financing cost
Nuclear plants tie up a lot of resources to produce a very long-lived asset, which takes a long time to start producing a return and much longer to pay itself off. Projects of this type (whether for energy or anything else) must provide enough return to compensate for this long time period (as well as simply the material resources and labor)
(sane regulations as in something much closer to common law, in which the party is free to do as they please but held liable for any damage... in the case of nuclear perhaps insurance or some sort of surety bond can be required, but nothing more than this)
