  2. Refrigerant reclamation - Wikipedia

    en.wikipedia.org/wiki/Refrigerant_reclamation

    In general, recycled refrigerant is refrigerant that is cleaned using oil separation and single or multiple passes through devices, such as replaceable core filter-driers, which reduce moisture, acidity, and particulate matter. These procedures are usually implemented at the field job site."

    en.wikipedia.org/wiki/Nuclear_reactor_safety_system

    An LPCI is an emergency system which consists of a pump that injects a coolant into the reactor vessel once it has been depressurized. In some nuclear power plants an LPCI is a mode of operation of a residual heat removal system, also known as an RHR or RHS but is generally called LPCI. It is also not a stand-alone valve or system.

    en.wikipedia.org/wiki/Thermal_expansion_valve

    A thermal expansion valve or thermostatic expansion valve (often abbreviated as TEV, TXV, or TX valve) is a component in vapor-compression refrigeration and air conditioning systems that controls the amount of refrigerant released into the evaporator and is intended to regulate the superheat of the refrigerant that flows out of the evaporator ...

    en.wikipedia.org/wiki/Automotive_air_conditioning

    The second automotive air conditioning refrigerant invented was R-134a. R-134a is a hydrofluorocarbon refrigerant that contains fluorine and hydrogen. The successor to R-12, R-134a was a new refrigerant that no longer contained chlorine that could deplete the ozone layer. R-134a is a greenhouse gas, it has a lower global warming potential than ...

    en.wikipedia.org/wiki/Boiling_water_reactor...

    The Reactor Protection System (RPS) is a system, computerized in later BWR models, that is designed to automatically, rapidly, and completely shut down and make safe the Nuclear Steam Supply System (NSSS – the reactor pressure vessel, pumps, and water/steam piping within the containment) if some event occurs that could result in the reactor entering an unsafe operating condition.

  7. Nuclear reactor heat removal - Wikipedia

    en.wikipedia.org/wiki/Nuclear_reactor_heat_removal

    The removal of heat from nuclear reactors is an essential step in the generation of energy from nuclear reactions.In nuclear engineering there are a number of empirical or semi-empirical relations used for quantifying the process of removing heat from a nuclear reactor core so that the reactor operates in the projected temperature interval that depends on the materials used in the construction ...
