Shortround I think you got the TMI reactors mixed up. Unit 2 went into commercial operation Dec '78, accident was March 79. All the expense of construction and only made money for three months. I first worked there in 2000. I worked each U1 refuel from 2001 thtough the final refuel in 2017. I retired just before the 2019 defuel. I still have and odd left work boot as a souvenir. The right one got crapped up and is now buried at the Barnwell SC low level radwaste facility. Maybe it was transported in a DI styled covered hopper! LOL!
