Yeah, for sure. The idea is that unlike an LWR/HWR, which requires the insertion of shutdown/control rods or the injection of gadolinium nitrate to kill a critical core in the event of an incident that could result in a power excursion or fuel melt event, no such requirement should exist for an FBR, since it is self-regulating (doesn't have a moderator or control rods) and in the absence of coolant, reactivity naturally decreases and the fuel, designed to operate at the maximum temperature the unit is capable of, would not be at risk of melting.I have an issue, as I am sure you can imagine, when people tout anything as being "foolproof" or "unable to fail" and so on. In that world, it is a dangerous claim to make.
At least that's my understanding of it. It's a pretty "diverse" subject because there are so many different designs and not all of them are sodium cooled, fuelled the same way, or regulated the same way. You can get a sense of that from the WNA link I provided earlier, which provides summaries of most of the designs.
Not directly? lol. I'm "involved" in the field, due to an advocacy organization I was involved in founding and have spent, and spend, a considerable amount of time researching it.I suppose you work in this field?
