If Tboom is temperature, then given a sealed containment of a fixed density, (volume does not change, mass decrease very slowly), vboom is fixed and so is Tboom
vboom=3.4354∗densityZ
Density fixed, vboom fixed.
Tvboom=(3.4354∗densityno.ofparticles)2∗molarmass∗10−33∗8.3144
Density fixed, Tboom fixed.
For any sealed reactor, a particular Tboom given the density of the material in the reactor.
At Tboom, the reactor releases huge amount of energy that resist any drop in temperature. The reactor remains at Tboom. It is still possible to over-drain the reactor and drive it below Tboom. Below Tboom temperature decreases.
In other words, fill up the sealed reactor full!
