Ran across these articles today and, since it had been discussed
before, thought they might be of interest.

Close Call with Catastrophe in Sweden? An observer has called last
week's mishap in Sweden the worst incident to befall a nuclear power
plant since the accident at Chernobyl. Nobody was injured, but for 22
minutes, workers had no idea what was happening in the reactor's core.
Swedish officials have taken half the country's nuclear power plants
offline until it can ensure their safe operation."

"This is absolute nonsense. The unit is in perfectly fine condition,
plant management has sent in a report to the Swedish regulator (SKI) and
is now awaiting permission to restart. No equipment is damaged, and
reactor safety was never compromised."
The blog you quote also says:
"The serious aspect of this event is that the automatic power supply of
safety systems were partly compromised because of a fault in the external
grid. Because of possibilities of similar design, further three reactors
in Sweden have been taken offline, and will not be restarted until the
risk of a similar event is removed."
From the SKI website:"SKI-investigation of Forsmark 1
....
The investigation team concluded that FKA actively processed available
information in order to find the cause of the event and to work out
actions to be taken to handle the problems. SKI concluded that the FKA
assessment of the gravity of the situation was correct as important safety
related equipment failed to work.
Description of the event
After the electricity failure caused by the short circuit in the
switchyard the Forsmark 1 reactor was scrammed and a number of safety
systems were activated. The reactor being shut down could be concluded by
the surveillance systems but the indication of the position of the control
rods was unclear due to lack of power supply. The emergency cooling system
did for a short period of time pump water into the reactor vessel. Also
the water spraying system in the containment was activated. The personnel
kept watch over the water level and were prepared to activate further
safety actions in case the water level should decrease further. After 23
minutes the two remaining diesel generators were started and the water
spraying was terminated.

"The French Turn Against Nuclear Energy France is one of the world's
leading producers of nuclear energy. But a new poll shows that the
French aren't happy about this anymore."
