IMHO, quiescence is caused by deterioration of the micro-powder surface due to inadequate heat control.
I speculate that DGT has move the heat producing powder zone to the reactor vessel wall. The powder is mechanically affixed to the reactor vessel wall with excellent heat transfer characteristics. Because of this design change, the temperature of the powder will never exceed the coolant temperature and therefore is "idiot proofed" But in order to get the powder above the Curie temperature of nickel, the coolant must support very high temperature heat transfer in excess of 400C.
