    if only you spent as much time answering basic questions of how much and how long current approach would take as inventing figures while we remain the most expensive electricity in Europe and one of the most polluting

    once again nuclear won’t make us cheaper. …

    You have spent 0 time answering the above regarding Nuclear.

    Why should we waste our time on your idiocy.

    Nuclear won't deliver any savings because it's an unreliable dead end technology that isn't a fit for our grid.

    The risk factor, 50% of USA reactors that started construction since 1978 have been abandoned. Another nuclear disaster would pull the rug out from any project. As would a political party dead set against foreign dependence getting into government.

    Nuclear is never on time or on budget. Factor at least a doubling in price for every 10 years construction. Delays of a decade for European Gen III reactors is the norm now. It means the even in the best circumstances the costs of financing are going to soar, and predictions of costs are meaningless.

    Nuclear missed the bus. Most of the increase in demand will be sorted long before nuclear arrives.

    And nuclear is unpredictably intermittent. It's more trouble than it's worth on a grid our size. The requirements for spinning reserve and backup would wipe out any supposed benefit.

    And nuclear can't do better than 70% on an island grid. So you still need that dispatchable peaking plant.

    We could easily get to 70% with renewables long before we could start construction of an NPP.

    "The present cost for the 37GW plan for turbines alone is now €150 Billion."

    Sizewell-C will cost £100Bn It's nominally 3.2GW but because existing EPR's only average around 70% it's more likely to be 2.25GW.

    Also it's not going to provide any power anytime soon.

    And you have no plan for when multiple reactors go off line at the same time. And Nuclear can't ramp up fast enough to provide it's own spinning reserve. And Iodine pits means hard limits on attempts at load following or rapid restarts.

    First sensible thing I've heard from FFG on the matter for the past 25 years - unfortunatly they have a pair of idiots in charge of the relevant Departments that are only interested in phote ops to promote the greenwash con of wind powered data centres on state peatlands🙄



  • Registered Users, Registered Users 2 Posts: 16,965 ✭✭✭✭charlie14


    Nuclear is the generation our grid was designed for.

    Large capacity generating plants close to where the highest demand was. It was not designed to have every line down to the most local being used as a deliverer of generation while at the same time being use by renewables as a push back - for solar with the added problems of thousands upon thousands of inverters to convert DC to AC - that would require an upgrade costing €20 Billion paid for by the taxpayer and consumers that these renewable companies are not going to contribute a cent towards.

    Wind has increased in price by 75% in just four years. That is verifiable as I have shown earlier today. Doubling in ten year for nuclear is a figure off the top of the head from someone who was predicting massive reductions in the cost of wind in 2022 when turbine manufacturer were going to the wall and still refuses to see how wrong they were.

    As to which is intermittent you have only to look at the capacity factor of renewables and nuclear to see which are the main culprits.

    Presently we have 7.5GW of renewables installed capacity for a 6GW grid where last year we imported ~15% of our requirements. We will not even reach 23% of the 51% requirement on emissions by 2030, and we have the most expensive electricity in Europe for a country with the same population as Finland whose electricity costs are one quarter of ours. So what have renewables given us to date ?

    To continue with the same with this 37GW offshore hydrogen plan would require, for the turbines alone, a capital investment of €450 Billion for the 60 year lifespan of nuclear - also verifiable in real world examples I posted today - and would still not provide our 2050 requirements and see us burning more gas than we are now.

    Wind priced itself out of the market four years ago and those companies have resorted to blackmailing countries now to get the strike prices and terms they want. This hasn`t gone unnoticed with countries now looking to those with cheaper electricity and seeing it is not sheer coincidence they are those with nuclear in their mix, and that those state owned are using the profits from that nuclear generation to provide their consumers with reasonably priced electricity and following those examples. Poland and Belgium for starters.

    When you see the biggest political party here now in favor of lifting the ban on nuclear, it says a lot about how the wind is now blowing. And it`s not through an offshore turbine.

    Lol, profits from Nuclear???

    Thats like when my kids make a 'profit' selling lemonade at a euro a glass even though they didn't pay for any of the ingredients or the tables or chairs for their lemonade stand.

    Nuclear fission was invented in 1938. The first plant was built in 1951, 13 years later.

    Why, 70 years later would it take 3 times longer to build a plant?

    That aside, if it is going to take 40 years to build a plant then we better get started. Its just going to cost more money to continue to delay the delivery.



  • Registered Users, Registered Users 2 Posts: 24,491 ✭✭✭✭ted1


    The world's first metro (the London Underground) opened in 1863, taking about three years to build.

    So far it has taking us 26 years and no ground has been broken


    you must be very naive or don’t understand what’s required to build large infrastructure projects in Ireland.

    French nuclear for the past 3 years while keeping the lights on in Europe, have made a profit of over €5 Billion each year from exports alone. It would have been even larger had the not been compelled under the ARENH mechanism to sell an even greater volume to renewable companies to keep them in business since 2011 @ €0.042/kWh. For context we are paying €0.404/kWh. 10 times more.

    Take a look at the lowest prices for electricity in the E.U. and compare them to the highest and then tell me that nuclear plays no part in those countries having cheaper electricity and it`s all down to renewables.

    Or even explain why the outlier of the most expensive, Belgium, is now nationalising it`s nuclear and adding further nuclear for any other reason than to do the same as the lowest priced countries that are using their nuclear generation to provide their citizens with reasonably priced electricity. Poland also going the same route.



  • Registered Users, Registered Users 2 Posts: 24,491 ✭✭✭✭ted1


    using todays money it is 6 times dearer to built a NPP than when those countries such as France and Finland built theirs in the 60s



  • Registered Users, Registered Users 2 Posts: 14,785 ✭✭✭✭LambshankRedemption


    you must be very naive or don’t understand what’s required to build large infrastructure projects in Ireland.

    I asked a simple question and your initial reaction was to call me naive and that I don't understand large projects.

    Charming.

    Poland is building three NPP`s with an installed capacity of 3.75GW for a capital spend of €45 Bn. with a lifetime of 60 years. With their capacity factor they will deliver 1GW for €13 Bn. 24/7 regardless of weather.

    Our current plan is for 37GW offshore installed capacity plus hydrogen. With their capacity factor the would deliver 15.54GW, only half of which (7.77GW) going to domestic consumption. The other half to hydrogen generation.

    Presently the turbines alone for that 37GW will cost €150 Bn. with the cost having increased by 75% since 2022. Their lifespan is one third of a NPP so on a like for like basic over 60 years the capital spend without inflation or further price increases would be €450 Bn.

    Even if all that generation went to domestic supply it would cost €29 Bn. for 1GW. Over twice the price of Poland. With just half to domestic supply it would be €58 Bn. per GW, 4.5 times greater than Poland. And that is just for the turbines. Green hydrogen would add multiple billions.



  • Registered Users, Registered Users 2 Posts: 24,491 ✭✭✭✭ted1


    let’s add context.


    Poland initially planned one in 1956

    In 1986 they gave the go ahead, construction started in 1982 and stopped in 1990.

    They rebooted the program in 2009

    Construction is due to start in 2028 and come on line in 2036

    No doubt it’ll be delayed and over budget.

    The average building costs of a 100. Sqm house in Poland is 70k, it’s 250k in Ireland.

    That 43bn. Could easily be over €100bn here

    how long do you think we could Deliver one ?



  • Registered Users, Registered Users 2 Posts: 16,965 ✭✭✭✭charlie14


    Let add a bit of further context.

    That €450 Bn. capital spend on a like for like basis of 60 years is only for the capital cost of the offshore turbines alone, seeing as you are good at guesstimates seeing as the cost of offshore has increased by 75% since 2022 - 20% in the last two years - how much will that €450 Bn. grow too over those 60 years ?

    Neither does that €450 Bn. include the capital cost of producing green hydrogen so if you have a guesstimate for that as well for 60 year capital costs we can then take a look at your guesstimate of it costing us €100 Bn. for 3.75GW of nuclear and see which fairs best.

    As regards context that`s fair is it not ?

    What I'm trying to say is dont be waiting for cheap electricity from nuclear , even if we signed up immediately, at the same strike price as the poles are likely to announce, that price obviously wouldn't kick in till the plant is commissioned and producing electricity.. that price is fixed but index linked for 40 years ( probably) , its also a 24 hr - 365 days a year price - 3 am low demand for power - the grid is still paying the same price ,

    Plus all the other grid costs , including spinning reserve, transmission, grid stabilization ect still have to be added

    Thats not to say Nuclear energy is not value - but dont think its gonna be cheap.. maybe if the state owns the NPP after the 40 years of operation, they can then use that to put cheaper electricity onto the grid . ( After theyre paying any refurbishment costs ,and putting aside money for decommissioning)

    France stopped building Nuclear power plants in the 80s , partly because it got too expensive, and that was pre chernoble + - partly because they overestimated their electricity demand

    The US similarly stopped about the same time .

    Quelle surprise that again another poster that is opposed to nuclear fires around guesstimate figures off the top of their head that suit, while refusing to do even that for those that do not, while asking others for verifiable data and timelines while ignoring verifiable data already provided.

    Incidentally, wind turbines have gotten considerably dearer, largely due to commodity prices , development costs and risk ..

    All that affects nuclear too .. but the risk even more so because the timeframes are longer ,

  • Registered Users, Registered Users 2 Posts: 16,965 ✭✭✭✭charlie14


    Well France and others are back in the game now, and it`s not difficult to see why when France nuclear exports are now making a €5 Bn + profit annually that is keeping their electricity charges low or that Poland and Belgium are also going down the route of those other countries that have the cheapest electricity charges in Europe due to nuclear in their generation mix.

    That countries are now being held as hostages for ransom by renewables is adding to that



  • Registered Users, Registered Users 2 Posts: 24,491 ✭✭✭✭ted1


    what number did I fire around ?

    I substantiated my costs by comparing building costs in Poland to Ireland

    When did I ever say i oppose nuclear?

    All along I’ve said it would take 2 long to build and to costly. But I never opposed it.



  • Registered Users, Registered Users 2 Posts: 24,491 ✭✭✭✭ted1


    You keep missing the points that France built nuclear when it was cheap to build



  • Registered Users, Registered Users 2 Posts: 16,965 ✭✭✭✭charlie14


    Finland`s OL 3 1.6GW NPP went on line in 2023. Even years late and over budget it cost €7 Bn. per GW.

    France is planning to add 14 with the initial phase featuring 6 confirmed with a combined capacity of 10 GW for €75 Bn. €7.5 Bn. per GW.

    It doesn`t look as if either share your view on nuclear being too expensive now. Or indeed when you see the profits France is making exporting nuclear and the prices both countries consumer are now paying for their electricity compared to ours. If anything Finland`s OL 3 is a standout for nuclear in how it so drastically cut the price to the consumer plus the reduction of it`s energy imports

    How much would the capital cost for renewables be to to provide 1 GW over a like for like 60 years ?

    And before you do the usual anti nuclear of the cost rising, offshore has risen by 75% since 2022. 20% in the last two years alone.

    ”Why is the price of electricity so high? It’s a puzzle”

    Yeh right mystery alright /s

    Anyways professor outlines it all quite clearly, and we following the worst aspects of the UK path

    Fission was discovered in December 1938.

    Series production of breeder reactors started in 1943. They lost three months to the hubris that still permeates the nuclear industry when they ignored General Groves' request to keep running the first reactor for longer to see what happened. Even so the first irradiated slugs were discharged from B Reactor on Christmas Day, 1944.

    Seven years to go from discovery of fission to having to remove 250MW of heat per reactor.

    Find out how much Finland spent on electricity imports during those 11 years.

    France's new plants have increased in cost by 40%. Which is interesting considering they won't start construction for years. Which also means they're delayed. And at best they'll only match 2005 levels of production. So no nett gain.

    OLK-3 so far only averaged 10TWh a year. That makes it a 2.25GW on average. It's the best performing EPR as it hasn't been offline for a full year. In comparison wind produced 19.8TWh in 2024 in Finland.

    France exports less electricity than their renewables produce so none of this is a nuclear success story no matter how you try to spin it.

    Capital cost for 1GW ?

    Solar and storage costs are still in freefall and anything that arrives before 2045 is ahead of nuclear.

    Now, Now - don't you know that wind power is cheap and cheerfull in the Tellytubbly land that is Energy policy in Ireland….

    PS: An energy specialist on Newstalk yesterday said that Irish Energy prices are now among the highest in the world, let alone the EU!!

    you don't need to be specialist to say that.

    Here's the thing, just because someone specialises it doesn't make them any good, always look for an expert.
