It really is a good idea BUT :
1) Inevitably the DOI would be involved, I wouldn't trust them with a tram let alone a nuclear reactor, the thought of the current idiots being let anywhere near it frightens me to death
2) We would of course have to set up our own nuclear inspectorate as it would be unacceptable to use the existing UK expertise, despite the fact that we have no idea what we are doing (eg Crogga)
3) Whatever it is budgeted for once our CS and Tynwald get their hands on it the costs would escalate and it would end up far more than buying energy from elsewhere
So for all those reasons, NO NO NO.
