They don't want to what? Don't want to give up poorly designed regulations? Or do not want nuclear power?
The latter is largely due to the anti nuclear movement, as sponsored by the petroleum industry. This will go down in history as one of the biggest self-owns in trying to protect the environment.
And we're back to the beginning. One of the major costs of current reactors is regulatory burden. One of the reasons we don't see improvements in costs is it is extremely hard to release changes or new designs.
