Sorry Dux, I should have elaborated.
The EPR is the European Pressurised Reactor, or when you want to sell to China or USA, The Evolutionary Pressurised Reactor.
The EPR is essentially just the latest version of Koeberg, it has a lot of new features, some of the main ones are the "passive" safety features, the roof has a massive "fire pool" built in, so the reactor overheating system is not pump driven needing power for the pumps and has fusible plugs not electrically driven valves, so no power related safety systems. There are loads of other upgrades in the detail.
One of the big issues for the constructors, is that the acceptance standards were set years ago, but technology races forwards so the Examination Techniques mean you can find defects which you would historically not found, the safety factors are there to protect for such defects, but the balance between the NDE techniques and the Acceptance Standards are getting blurred as the Codes do not always keep up.
We had a technique called "phased array" used on equipment, where we had a supposed "weld defect" it was picking up the difference in grain structure between the root of the weld done with TIG and the balance of the weld done with Submerged Arc Welding, these can be very expensive discussions if it goes against you.
SMR's are not a reality yet and I am not convinced they will be in our lifetime.
