  • Moreover, the supercritical CO2 has a higher density than subcritical fluids, so there is potential to reduce the size of hardware.

And then the question becomes, is this subcritical or supercritical?

  • And then the question becomes, is this subcritical or supercritical?

  • But surely even a well-designed floor could prevent a critical-sized pool; some melts over here, some melts over there, into separate subcritical pools.

  • If the control rods have melted, or if any portion of the core has melted into corium, it can go subcritical and still be actively fissioning, just not at critical self-sustaining levels.

  • For example, in 1997, as part of the Stockpile Stewardship and Management Program, the Clinton administration launched a $40 billion program of high-speed computers and other means of simulating or conducting subcritical underground explosions at the government's Nevada test site.

  • The experiment was conducted under subcritical conditions to ensure safety.

  • In a subcritical state, the material remains stable and does not undergo phase changes.

  • The researchers measured the properties of the subcritical fluid to understand its behavior better.

Morphology

subcritical = critical (semi-transparent) = sub + critical

The segmentation sub- + critical is clear, but understanding the precise meaning requires domain knowledge of what 'critical' refers to in the scientific context.

Etymology

Subcritical is made of the prefix sub- meaning 'under' or 'below' (as in submarine or subway) and critical meaning 'a very important point or limit', like a 'critical decision'. So subcritical means 'below the critical point', and it is used when something is under the level needed to change state, for example when a liquid will not turn into gas.
