This is much better than 2 or 3 mega projects.https://www.bbc.co.uk/news/science-environment-54703204

If these can delivered affordably, then it sounds a good idea.
I am not anti nuclear but am opposed to Hinkley on cost grounds and also opposed to chinese innvolvement on national security grounds and for qaulity control reasons.

440 Mw is not exactly small, it is only slightly less than the output of our existing nukes. Which are in the 500 Mw to 600Mw range.

One of these proposed reactors would meet nearly 1% of the peak demand, A dozen would have a similar output to the present nuclear fleet.

I am still a bit doubtful about this ever progressing beyond the stage of studies, reviews, and consultations.

Who is going to pay for the security of these? Hopefully it will be the consumer rather than the tax payer because I don't want to have to pay for something that I don't use and have made considerable efforts not to use. Security should be a cost for the owner of the plant rather than the taxpayer or if security is provided by the taxpayer it should be charged to the owner as it is one of the costs of dangerous nuclear power.

Small nukes will be better than large ones from the point of view that if one goes down for any reason it won't have too much of a effect on the grid.

I was wondering about the possibility of putting them offshore, this would address some of the security concerns. It would also remove the need to purchase land, and as many people would object to living near to a nuclear facility it would take that issue away as well.

Problem with offshore is you need to get the transmission network out there. That adds huge costs in terms of cabling and offshore substations. Access for maintenance is also an issue.

I think that offshore is a greater security risk, vulnerable to foreign naval forces and to terrorists in boats, and russian "trawlers"

If these are to be built, I would prefer to see groups of perhaps four or five reactors on land.
Security is cheaper per reactor if they are grouped together.
Transmission lines would aldo be cheaper, remembering that these need duplication for nukes.
