For a start, the reactor had no containment building, which would have prevented most of the radiation from escaping into the environment. The RMBK design also suffers from a number of other potential flaws, a major one is the lack of dynamic stability. In most western reactors, a higher reactor temperature drives down the output power level, which in turn brings down the temperature. This was not the case in Chernobyl-style reactors, which mean they are more susceptible to run-away reactions. Also unlike western reactors, the RMBK design employs a moderator that is potentially combustible (graphite), and has limited safety systems, especially for dealing with a loss-of-coolant accident.
That sounds like what I read too.
