It is true that larger countries, including Britain, France and USA, build bigger and bigger nuclear plants as their needs grow and as technology develops, but there are plenty of smaller reactors currently available and being used around the world.

But, just the same as not all aircraft are Jumbo jets, not all nuclear plants are huge either.nuscale-boat-transport1

What size power station is acceptable in Ireland? We currently have a range of sizes feeding into our electricity system, ranging from small domestic wind and hydro turbines of a few watts up to the largest units of around 400 MW. For example, Moneypoint has 3 units of around 300 MW each.

While the system could take much larger units with larger overheads, it is accepted that the largest economic plant size is around 700 MW, while 500 MW size would be ideal for base load plants.
