Olympic regeneration in the Lower Lea Valley could be held up by the presence of a long decommissioned nuclear reactor, according to this article in the Times. A fact that was apparently not mentioned to the IOC when London was presenting its bid to host the games. This is hardly Chernobyl though - the reactor was built by Queen Mary College's department of nuclear engineering and the "core was the size of a bucket and produced virtually no energy". Still it only took one bite from a irradiated spider to give Peter Parker some pretty exceptional crimefighting skills. Just think of the consequences for the Olympic movement.
