It wasn't widely know, it was "noticed", in a "how strange" sort of way.

These points only apply IF you drive it outside the envelope


One of the impressions you get from Chernobyl is that the operators
behaved the way they did because they felt they had a sure fire fail
safe, scram, to shut down the reactor.

It is slightly concerning to see the same over confidence in safety
systems reflected in this thread.

The western systems are probably safer and better run, but to quote
Schiller:Â* "Against stupidity the gods themselves contend in vain."

The Western systems simply would not allow the RBMK reactor and its
inherent problems.

The design meant that in an emergency, rods could not be inserted
rapidly and that for the first part of their insertion, power output
would rise. Clearly a dangerous combination.

It was known and they decided to ignore it.

Possibly not known to the operators?

The point is that it was known to the Soviet Authorities and they
decided to ignore it and go ahead anyway.
