Even if we totally ignore the potential environmental impacts of nuclear power, the economics simply do not add up when you include ALL costs.
The cost of building the plant runs into pretty enormous money to start with.
Then you've got the on-going maintenance, fueling and running costs which are quite high.
You've got major security costs, particularly somewhere like Ireland where there is a genuine and real terrorism risk.
Then you've got the elephant in the room : fuel disposal and decommissioning costs. These are astronomically expensive.
The decommissioning costs for the UK's legacy of nuclear power is running at £73.6 billion at the moment and will probably cost a lot more than that as that estimate's coming from the industry itself and the UK Government.
Some estimates put it at more like £160 billion!!
Admittedly, it's still possibly cheaper than decommissioning Anglo Irish Bank! (which is an entirely different story) but, I don't really think Ireland could afford to run a nuclear programme.
Also, if you consider the vast cost of building and running these plants, how much CO2 would be saved by putting those billions into say energy efficiency programmes for homes and buildings?
Or, lashing it into public transport in the cities?
I think it could easily offset the CO2 savings of a couple of nuclear reactors!
