A review on the integration of mainstream P-recovery ...

A third crystallization reactor (PRE-SBR) was designed so that the supernatant extracted after the anaerobic phase of HET-SBR could be used for P-recovery. An additional interchange vessel was required to interchange supernatants amongst these reactors, in order to avoid idle phases and to ensure that all three reactors could operate ...

Sodium-Cooled Fast Reactor - an overview ScienceDirect ...

Malcolm Joyce, in Nuclear Engineering, 2018. 11.7.3 Sodium-Cooled Fast Reactor. The sodium-cooled fast reactor (SFR) Gen IV system is considered to be the design with the greatest maturity for the burning of minor actinides (MA) because fast spectrum neutrons generally have a greater probability for the fission of MA than thermal. As a fast reactor, the …

Melting - Wikipedia

Melting - Wikipedia

Melting, or fusion, is a physical process that results in the phase transition of a substance from a solid to a liquid.This occurs when the internal energy of the solid increases, typically by the application of heat or pressure, which increases the substance's temperature to the melting point.At the melting point, the ordering of ions or molecules in the solid breaks down to a less …
