Australian news report from 7
Australian news report from 7 National News covering the cracked fuel rods incident at Pickering Nuclear Generating Station on the north shore of Lake Ontario in Pickering, Ontario. Aired December 31, 1983.
From wikipedia: "A serious incident occurred on 1 August 1983. Pressure tube G16 in the Pickering A Unit 2 reactor developed a 2 metre long split. The reactor was safely shut down and the damage investigated. The cause was found to be the mislocation of annulus gas spacer springs which allowed the pressure tube to sag inside the calandria tube leading to hydrogen enrichment of the cooler areas. This made the tube more brittle so that it ruptured. There was some local fuel damage and the reactor was safely shut down by the operators with no increase in radioactive emissions. The eventual resolution was Large Scale Fuel Channel Replacement and all the pressure tubes were replaced in all Pickering A reactors. Since then, additional monitoring of the location of the annulus gas spacer rings has been a significant part of routine reactor inspections."
