Aqueous homogeneous reactors (AHR) are a type of nuclear reactor in which soluble nuclear salts (usually uranium sulfate or uranium nitrate) are dissolved in water. The fuel is mixed with the coolant and the moderator, thus the name "homogeneous" ("of the same physical state") The water can be either heavy water or ordinary (light) water, both of which need to be very pure.

The biological hazards associated with a homogeneous reactor are due chiefly to the radioactive rare earths, alkaline earths, and iodine .
Fluid Fluorides and Chlorides Reactor Research and Development on Molten Salt Reactors (MSRs) Papers, Books, and Reports. Dedication: This site is dedicated to Dr. Uri Gat, who introduced me to Molten Salt Reactors in and Dr. Ralph Moir, who continues to help and encourage me and many other pilgrims, in our "Molten Salt Adventures" , but . The homogeneous reactor systems considered include one- and two-region reactors, breeders, converters, and burners. Although no one fuel or type of reactor shows a marked advantage in power cost over all the others, the superior fuel utilization of a thorium breeder system suggests that it is potentially the most economical one for power.

The two purposes of water in a reactor core are _____. a. neutron absorber and heat transfer liquid b. neutron moderator and heat transfer liquid c. neutron moderator and neutron absorber d. neutron absorber and lubricant e. neutron moderator and radiation shield.

Reactor Vessel The reactor core, and all associated support and ali gnment devices, are housed within the reactor vessel (cutaway view on page ). The major components are the reactor vessel, the core barrel, the reactor core, and the upper internals package.
The reactor vessel is a cylindrical vessel with a hemispherical bottom head and a. The difference in the three PJ models (one-region, simplified one-region, and two-region), shown in their final form in, respectively, is most effectively shown graphically in Fig.

Two-region homogeneous converters may also be fueled with either D 2 O solutions or slurries; in these reactors, however, the U is in the core and the fertile material in the blanket. Converters of this type become breeders if the bred fuel is subsequently burned in the core and there is a net gain in the production of fuel.
Heterogeneous Core. Most of PWRs use the uranium fuel, which is in the form of uranium m dioxide is a black semiconducting solid with very low thermal conductivity. On the other hand the uranium dioxide has very high melting point and has well known behavior.

heterogeneous reactor[‚hedərə′jēnēəs rē′aktər] (nucleonics) A nuclear reactor in which fissionable material and moderator are arranged in a regular pattern of discrete bodies with dimensions such that a nonhomogeneous medium is presented to neutrons. Heterogeneous Reactor a nuclear reactor that is constructed to isolate the fuel.
The two region-specific cross sections were combined and used for the core with heterogeneous lattice (i.e. lattice geometry explicitly modeled). The other cross section set was generated based on the lattice-averaged spectrum, in which case, the fuel salt and graphite cross sections were evaluated using the same : T.

The RBMK (Russian: реактор большой мощности канальный, РБМК; reaktor bolshoy moshchnosti kanalnyy, "high-power channel-type reactor") is a class of graphite-moderated nuclear power reactor designed and built by the Soviet name refers to its unusual design where, instead of a large steel pressure vessel surrounding the entire core, each fuel Generation: Generation II reactor.
Fluid Fuel Reactors. The customary approach to reactor development assumes that a reactor is primarily a mechanical engineering device—that the ultimate goal of economically competitive nuclear power will be achieved by simplifying the mechanical design and by making the fuel elements more reliable.Intended primarily for undergraduate chemical-engineering students, this book also includes material which bridges the gap between undergraduate and graduate requirements.
The introduction contains a listing of the principal types of reactors employed in the chemical industry, with diagrams and examples of their use. There is then a brief exploration of the concepts 1/5(1).depend primarily on whether a one-region reactor or two-region reactor is involved, since in the latter case special provision for removing the inner core may be necessary.
If it is feasible to construct the reactor vessel and core tank as an integral all-welded unit, the layout of the system will be considerably simplified.
