We were in the training facility which mirrored the actual control room of the plant. The trainer initiated the 3 Mile Island event and after about 3-5 minutes of clicking and clacking of switches and circuits, the test reactor was safely submersed in borax (I believe). The trainer said it’s a scenario that is often taught to trainees.
That’s neat.
Such a shame that 3 Mile Island happened. Shouldn’t have been that way, and we may not be where we are right now if it had been handled correctly.
