====Disadvantages====
* At temperatures above {{convert|1000|K}} the native metal form of several [[actinide]]s, including [[neptunium]] (melting point: {{convert|912|K}}) and [[plutonium]] (melting point: {{convert|912.5|K}}), are molten. This could be used to recover a liquid phase, raising proliferation concerns, given that uranium metal remains a solid until {{convert|1405.3|K}}. While neptunium and plutonium cannot be easily separated from each other by different melting points, their differing solubility in water can be used to separate them.
* If "nuclear self heating" is employed, the spent fuel with have much higher [[specific activity]], heat production and radiation release. If an external heat source is used, significant amounts of external power are needed, which mostly go to heat the uranium.
* Heating and cooling the vacuum chamber and/or the piping and vessels to collect volatile effluents induces [[thermal stress]]. This combines with radiation damage to material and possibly [[neutron embrittlement]] if [[neutron source]]s such as [[californium-252]] are present to a significant extent.
* In the commonly used oxide fuel, some elements will be present both as oxides and as native elements. Depending on their chemical state, they may end up in either the volatalized stream or in the residue stream. If an element is present in both states to a significant degree, separation of that element may be impossible without converting it all to one chemical state or the other
* The temperatures involved are much higher than the melting point of lead ({{convert|600.61|K}}) which can present issues with radiation shielding if lead is employed as a shielding material
* If filters are used to recover volatile fission products, those become [[low level waste|low-]] to intermediate level waste.
