There is this talk in the New York Times about venting valves :
What not use a proportional relief valve ?
But the consensus in the nuclear industry supports the existing systems. Douglas E. True, the president of ERIN Engineering and Research of Walnut Creek, Calif., said: “In some cases you can argue it might be better to have a rupture disk. In other cases, it would certainly be better to have a manually controlled system.” For example, he said, the disk is backed up by a valve that is normally in the open position. If the disk ruptured and there was no electricity, it might be impossible to close the valve, and the venting would be permanent.
