FT.com / Companies / Utilities - Countries question Areva's reactor design

Nuclear safety authorities in three countries have raised questions over the design of control and command systems in Areva's new generation EPR reactor, the latest in a series of blows to hit the flagship of France's international nuclear ambitions.

Authorities in France, Finland and the UK have asked for changes to ensure greater independence of the reactor's safety systems from control operations. "The EPR design, as originally proposed by the licensees and the manufacturer, Areva, doesn't comply with the independence principle, as there is a very high degree of complex interconnectivity between the control and safety systems," they said in a statement.

that was a failry minor comment that was blown out of proportion, simply because it is made public, like all French nuclear incidents, on the French nuclear watchdog website.

The watchdog itself intervened to say that the interpretation made in the media of this announcement was widely off the mark.

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.
