No. I meant fast neutrons. Without the water there will be only a spectrum of fast neutrons. Add water and the reactor will go critical just as it would if rods were pulled. FRC Sent from Mail for Windows 10

Without water—lost in the steam production—the negative temperature coeff. Is diminished or lost completely. The rate at which reactivity is added to the reactor is important in startup to avoid super criticality and an uncontrolled –run-away—reaction. Any positive temperature coeff.

As suggested, steam would reduce the flux of thermalized neutrons in the reactor and shut it down. To maintain criticality, reactivity would need to be added, probably by the movement of control rods to increase the flux of fast neutrons upon which criticality depended. Control systems,

There is known phenomenon in physics called the "longitudinal spin Seebeck effect". The leading paper seems to be from Uchida : Observation of longitudinal spin-Seebeck effect in magnetic insulators Appl. Phys. Lett. 97, 172505 (2010); https://doi.org/10.1063/1.3507386 The carrier of

Liquid salt is a bad idea for fissioin reactors IMHO. When it cools it becomes a solid and needs some heating to bring it back to a liquid. In general it does not afford good corrosion protection to reactor containment materials—like metal alloys---and is a difficult waste product to manage,

Robin, On first glance, one obvious thermodynamic problem is steam – in that every fission fragment capable of knocking off a neutron is also able to boil off several hundred million molecules of heavy water in the process of thermalizing. Consequently maintaining a liquid state with
