the problem with the new reactors (known as MAPLEs, also at aecl chalk river) is much more serious than that. the problem is that the design intended them to run with a negative void coefficient, but when they were tested upon commissioning it was discovered that they ran with a positive void coefficient, meaning loss of coolant could/would lead to an increase in reactivity, instead of the designed decrease. the seven years since then have been a battle between the physicists and engineers trying to discover the design flaw, and AECL and MDS nordion fighting over who should pay for the overruns.
