I don't doubt the nuclear watchdog felt the need to (or was forced to) play down the issue, but explain why it is a "fairly minor comment". The failure to follow the independence principle means that a small incident can break down safety and control systems meant to prevent a bigger incident (which, I note, was a point raised by EPR critics in the early 2000s already, in addition to the criticism of the core catcher concept) -- that is not a minor issue whichever way I look at it.

The Finnish authority also sought to play down the issue when an identical note was leaked. The also similar British criticism however IIRC was not a leak.
