How were NERVA and RD-0410 supposed to be stopped? You can't just switch the running reaction off, can you? And they were using the cryogenic fuel as the coolant, so in space they could have only been cooled when running, right?

Speaking of cryogenics, how does one prevent the liquid hydrogen from boiling off in space? Same question for methane and oxygen, although this is probably easier
