do the pwr have recirculation pumps if they dont..........where do they present the LOCA? cos in the bwr the loca is most likely to take place in the recirculation loops
@tavisho I have a senior reactor operator's license on a BWR, so I'm quite familiar with the failure mechanisms. That said, a PWR is different, of course, but depending on the manufacturer, they all have between 2-4 cooling loops which are similar to the recirc loops of a BWR. The DBA LOCA for my particular PWR is a double ended shear of cool leg piping.
@tavisho Peach Bottom Atomic Power Station. Dual unit GE BWR-4/MK-I containment. I am currently licensing on a westinghouse 3 loop PWR (the one in this video).
@JustinHEMI05 ok......im aplying to I&C supervisor or maybe i could go all the way and become and RO operator.......so.....maybe well be in contact. Bye 4 now
@Froginthemouth406 Why are you shouting? They weren't idiots, they just weren't well trained. What training do you have to make the statements you made? I ask because there IS, in fact, a time the emergency cooling pumps should be shut off. Because they didn't understand what their indications told them, they shut them off based on what they said. Hind sight is 20/20.
@wolfcatsden Yep is sure was. Had they left well enough alone, the plant would have taken care of itself. They didn't understand or believe what their indications were telling them, and they acted contrary to what they should have done. Of course, operators are trained much differently today, thanks in large part to TMI.
during this what would be the course of action?. dropping the rods to slow and stop the reaction or would they activate a secondary system to cool the plant ?
@wolfcatsden Well what you were witnessing is the plant taking care of itself. For the worst case scenarios, an operator really shouldn't have to do anything for many hours. All we would be doing was ensuring everything that automatically should have happened, did. Big picture, the control rods go in, the containment gets buttoned up, high and low pressure injection systems start and flood the core with large amounts of borated water. That is what is happening in this video.

wasn't one of the biggest problems with three Mile Island was that the operators interfered with the plants safety systems ?

That was very interesting. I would have went to lunch if I saw that happen.
