Unless you have some magic economics that says we dont have to import 60% of our power

Nuclear power stations are very expensive to build, to run, and to decommission. They are extremely expensive beyond belief if they explode have a small incident. The downside of such an incident is that an area the size of Munster becomes wasteland, and uninhabitable. Why do they build the Nuclear power station in very remote places if they are so safe?Because they are not safe!

No way we get planning an build nuclear in 3 years. More likely you're looking at 2040\50 by that stage you're looking at 80% from renewalable

Renewable energy sources (except for hydroelectric) are unreliable, and have to be backed 100% by a more reliable energy source (fossil fuels, or nuclear). Rather than spending billions duplicating infrastructure that only works a portion of the time, the govt should just build a nuclear power plant.

I personally think that the ?1billion they are going to spend on the M20 could be better spent building a new Cork - Limerick rail line and upgrading the Nenagh line as the main Limerick - Dublin line. The alternative to the M20 proposal could be done by upgrading the existing road with bypasses of Charleville, Buttevant, Mallow, and a motorway between Mallow & the Cork North Ring which would also have to be built of course. Also future proof the alignment so the M20 could be built one day when absolutely required. Instead of just a vastly superior M20 motorway connection, the Munster region could have a safe and vastly improved N20, a proper Cork - Limerick rail line, a proper ring road around Cork & a motorway as far as Mallow, a much improved direct Limerick - Dublin rail connection improving connection between limerick and satellite towns for rail commuters. We have to reduce our transport carbon emissions by 2025 or we will be fined ?75 million per year by the EU. Is there any merit to the above suggestion?

The cost of fixing Chernobyl is still racking up. They have just built a giant sarcophagus to entomb it, and had to put robots inside to try to clean it up, as the building will not last as long as the radioactive material inside. Nuclear reactors are too large for Ireland - one is too big for us, and we would have to redo the grid to cope with one massive generator, because it will not be built on Bull Island, probable Bere Island, or even far out into the Atlantic Ocean. I think it would be one infrastructure project that the parish pump guys will run a mile from.

First of all, reading some of these posts about how renewables are the future make me want to find a polyester dancing suit, some ridiculous platform shoes, a record player and some BeeGees and Boney M records and re-decorate my bathroom in brown wallpaper. Why? Because all this talk about renewables being the future was all the rage starting in at least the 1970s and was a big talking point for the "Build Moneypoint and lets burn coal!" protests in Carnsore Point in that decade. It wasn't true then, and it isn't true now. Solar in Ireland has one huge problem, one that will always be - Ireland's peak energy demand is in the winter. The lower the temperatures, the greater the demand. The second problem is electric cars, if there is a mass move away from petrol and diesel in cars, then people who have electric cars are going to want to be able to "fill them up" the same way as with petrol/diesel. i.e. anytime, anywhere. That means the total demand is going to increase, and very dramatically. There are not enough hilltops that can be carpet-bombed with these ugly, bird chomping, bat killing monstrosities referred to as "wind turbines" and there's no way that these will produce power when people need it (i.e. whether the wind is blowing or not) the cost of both building these things, building power lines out to them and backing them up with fossil fuels (which is the plan), is enough to: 1) Continue cook the planet with CO2 emissions, because fossil fuels won't be going anywhere. 2) Send entire species of bats and some birds to extinction (windmills are extremely harsh on avian wildlife) 3) Possibly cost enough financially to tear a nation asunder or at very least seriously damage its citizens quality of life.
As for uranium, there are 3 questions and you've managed to blur them in some weird way: 1) Where do you get it from? 2) how do you use it? 3) How much does it cost.
How much does it cost?
As to your point about nuclear plants just unceremoniously exploding for no reason, this is a fantasy. The worst nuclear accidents in history have all had very clear causes and in many cases there were warnings well in advance of the danger.
As to your point about nuclear being too large for Ireland, there is some truth to that, but only some.
Your complaint about "redoing the grid to accommodate a reactor in the Atlantic Ocean" firstly nuclear plants are always built on land, not at sea.
Secondly, your point about redoing the grid is exactly what is required for renewables because the best sites for things like windmills are nowhere near the areas of peak demand.

It is early days for renewables. Wind is not the only renewable, and it is not far from living memory when the first private ICE vehicles began travelling on our roads, and it is only a generation or so ago when the ordenary citizen could expect to own their own car (or two). Biomass might be significant, as could wave energy and tide energy. We used to feed horses which provided much of our needs, and ships sailed by wind. We always burnt sods of turf and logs to heat our cabins.

How is that proper national infrastructure that guarantees our energy supply - where on earth do you think that stuff comes from . We import 96% of natural gas needs and corrib wont even do half that before it starts to drop off As for storage - magic beans again there - show me any type of large scale accumulator apart from pumped storage thats in service or fully funded - anything over 100 MWh in the tank will do nicely thanks as we'll need hundreds of them for irish winters. the attitude here seems to be " I'll take the nuclear electricity from next door just don't tell me where it comes from " And as for It is early days - true . We're unlikely to get to 40% before 2025 and EVEN THEN most of it (90+% ) will be Wind which is not a predictable curve and so we need a huge traditional capacity for cold still winter days -- i.e. most of the time No - Wind isnt the only renewable - All our Hydros are only one or two %. Tidal is effectively fk-all Peat is not a renewable, at least not a proper one Biomass ? burn trees ? In Ireland we deforested most of the country - and I need on-Ireland resources, not imports do the research lads its not as if its hard to find. In order to make your figures work above you prob need a breakthrough in tidal power generation AND a breakthrough in giant batteries. Who knows ?
