Don't think you will hear many green power advocates admitting this.
Not in every place and situation. In a few, it makes sense. In many, the energy required to build everything, protect it, isolate the radioactive waste, outpaces the energy produced. In other words it costs more than it saves. Many cities use gas-turbines because they are over 65% efficient (thermal cycle) and are extremely reliable and scalable (can add one or two real fast as necessary). It's possible that technology could offer a cleaner nuclear or fusion solution in the future, but again, that's not where we are today.
