Objections in Ireland

It’s not safe No solution for wasteDoesn’t help emissionsUse in nuclear weaponsRisk of terrorismFuel will run outThey’re too bigThey’re too expensiveUse renewables instead


Fact or Fiction?

“We are not going nuclear because we are going down the renewables route.“

Minister for Energy (Eamon Ryan), Late Debate, RTE radio


Joint Committee on Climate Change and Energy Security

CER submission

“… gas and wind generation must be supplemented by other sources, whether coal with carbon capture and storage, nuclear or non-intermittent renewables.”


EirGrid

“concerns that the portfolio … dominated by wind … supported by gas ... exposes Ireland to risks both in terms of supply and price volatility.”


Airtricity

“a sustainable electricity system is the sum of a portfolio of interdependent technological solutions including renewables”

“Should competitive, flexible, smaller scale reactors be proven, then this is an option that Ireland should consider in the longer term.”


Wind output at system peaks

Realistic contribution of some renewables - global

Maximum additional (thermal equivalent) amounts:

Wind x 50 (~ 3 TW)Hydro x 2 (~ 1 TW)Biomass x 3 (~ 1 TW) total < 6 TWGeothermal x 70 (~ 100 GW) (need 15 TW)Marine x 500 (~ 100 GW)

Remainder from solar, fission, fusion and new technology

Fact or Fiction?

“Any reasonable cost-benefit analysis concludes that nuclear energy has no future“

Oisin Coghlan, Friends of the Earth

OR“..our electricity is more expensive … because they have nuclear energy, which is cheaper.”

Mary Coughlan, Tánaiste and Minister for Enterprise, Trade and Employment


SEI shows nuclear cheaper than wind

Fact or Fiction?

“Too big for the Irish Grid”

“Plant size is 1600 MW”


New nuclear plants by 2015-20• Toshiba 4S 10 MW• Hyperion 25 MW• PBMR 165 MW• Babcock & Wilcox SMR 185 MW• Westinghouse SMR 225 MW

10 new plants <= 700 MW will begin operation by 2012

Opportunity, not a threat!

Fact or fiction?

“nuclear energy is just as polluting in terms of carbon emissions as gas-fired power.”

Oisin Coghlan, Friends of the Earth


IPCC are unequivocal…

“Waste remains dangerous for hundreds of thousands of years” – fact or fiction?

"What is remarkable about nuclear waste is that it fades away. In 600 years the high-level waste from a nuclear power station is no more radioactive or dangerous than the uranium ore from which it originated.” James Lovelock
