Enrico Fermi I
In reference to Mike's (Vacerator) comments from material he recalls in the book, "We almost Lost Detroit."
This book was a work by the author John Fuller who also wrote about extraterrestrials and ghosts.
Not only did we not lose Detroit, we did not lose the power plant, we didn't lose the reactor, and we didn't even lose the reactor vessel.
The author is famous for putting fiction into real life events for sensationalism. (It sells books.) The title alone tells you its based on sensationalism. One of his comments he made was, "the engineers and reactor operators were walking on tip-toes in the control room, afraid they might jar the the fuel into critical mass."
The control room was in a separate building, ha. Not even close to the containment building.
Yes, there was an event at the Enrico Fermi breeder Reactor. The reactor was built in the very early sixties and went online in 1963. In 1966, a diverter flow plate loosened and moved, blocking the flow of liquid sodium to several of the fuel rods. This resulted in the overheating of the rods and partial melting.
The automatic monitoring systems notified the operators that the reactor was having trouble keeping two of the fuel bundles cool. The operators shut down the reactor.
The containment building floor was not even remotely "minutes away from melting through." Fuel would have had to have melted completely through the reactor vessel to have reached the containment floor. No fuel ever exited the reactor vessel. The reactor vessel was not even damaged.
The two, out of 92 fuel bundles, that were damaged were removed. Fresh fuel was reinstated, and the Enrico Fermi reactor continued to run, producing electricity for six more years, until late 1972 when it was shut down and the fuel core was removed. It was an economic decision. It was an older reactor and they would either put the money into it for a more modern and efficient core or not invest the expense in it. Detroit Edison decided the latter instead of the former.[this post was last edited: 8/17/2021-11:11]
