Cost is certainly relevant. Its the reason that older plants are shutting down in the US, because even though they are already operating they can't compete with gas. Cost is also the reason that what was supposed to be the reactor of the US's nuclear renaissance, the AP1000, has had all its projects cancelled. The two projects that started construction under Obama were financial failures, with one getting cancelled after spending $9B on a hole in the ground, the other is about to go online after going 2x+ over budget for time and money.
