QUASI-HOMOGENEOUS REACTOR (Patent) | OSTI.GOV

A reactor is described which circumvents the disadvantages of homogeneous and heterogeneous reactors by using a "quasi-homogeneous" type of fuel. The fuel is in the form of open-ended hollow structures, preferably Raschig rings, oriented randomly in the reactor; a coolant is arranged to flow around and through the rings to extract heat therefrom.

Nuclear Research Reactors - World Nuclear Association

Aqueous homogeneous reactors (AHRs) have the fuel mixed with the moderator as a liquid. Typically, low-enriched uranium nitrate is in aqueous solution. About 30 AHRs have been built as research reactors and have the advantage of being self-regulating and having the fission products continuously removed from the circulating fuel.

Design Principals for Aqueous Homogeneous Reactors

surprisingly little detail exists on reactor operating characteristics, particularly at steady-state. What data is available has been catalogued and extended by theoretical treatment to develop a prescription for successful design for aqueous homogeneous reactors (AHR) to produce 99Mo.

A fixed-bed reactor modeling study on the methanation of .

Different pseudo-homogeneous reactor models were compared in order to assess the needed degree of detail for modeling externally cooled fixed-bed reactors. Even the comparison at modest conversions showed that a simple 1D PFR model is capable of describing the qualitative trends and can be used for screening possible process conditions.
