“…Because of this, most schemes to extract heat from AHRs would have to employ the use of intermediate heat exchangers and/or steam generators. Such a heat exchange loop would probably be of the hi-lo-hi type with high isolation loop pressure that is seen in nuclear desalination applications to preclude the possibility of contaminating network fluids with reactor solution [14].…”

This chapter describes the potential of the aqueous homogeneous reactor, briefing readers on the physics and history of the subject, whilst providing both current and possible future applications for this reactor technology. These reactors were some of the first nuclear reactors ever constructed, and provided valuable information on critical mass and other nuclear physical properties on fissile solutions. The compact nature of these reactors, combined with their inherent safety characteristics, have made them attractive for the generation of medical radioisotopes and neutrons for experimentation. However, material corrosion issues and advanced development of solid-fuelled light water reactors would curtail much interest in the technology in the 50’s. Although operating temperatures of this type of reactor are usually low, even such low temperature heat is useful in process and industry; such a reactor can be used for environmentally-friendly district heating or the supply of process heat in industry, and could even be used to produce hydrogen. With modern advances in physics and chemistry, and disruptions in conventional energy sources; such reactors in their modern form may serve an important role: supplying various energy demands that could be derived from nuclear power, but may not require more advanced and costly reactor technologies.

“…Se ha llamado así a los procesos en los cuales se emplean la energía procedente de un reactor nuclear en un proceso de desalinización, generalmente de agua de mar [22,23]. Es importante mencionar que la desalinización propiamente dicha se realiza en una planta de desalinización acoplada al reactor que emplea un método como destilación multiefecto (MED), evaporación instantánea multietapa (MSF) como se muestra en la Figura 3, ósmosis inversa (RO) [24], etc.…”

El agua de mar desalinizada ha llegado a ser una fuente importante de abastecimiento para grupos poblacionales en todo el mundo debido a la creciente escasez de agua para consumo humano. Muchos factores han aportado en ello, la abundante disponibilidad de agua de mar y salobre, la diversidad de métodos desarrollados, sus continuas mejoras y la paulatina reducción de costos. Los principales métodos usados son la ósmosis inversa, la evaporación instantánea multi etapa y la destilación multi efecto, los cuales han mejorado su eficiencia debido tanto a la experiencia con las plantas desalinizadoras como a las investigaciones y desarrollos teóricos recientes. En este documento se presenta una revisión de los métodos de desalinización, tanto de aquellos que se vienen empleando desde hace tiempo, como de nuevos métodos reportados, así como algunas consideraciones respecto a la energía empleada y los costos del agua desalinizada obtenida.

“…To decrease or completely remove the leakage probability of isotopes of radioactive elements from the nuclear power unit to the desalination plant, two possible designs are suggested. The first design is a "high-low-high pressure configuration", and the second design is a "low-high-low pressure configuration" [37]. The first configuration means that the intermediate circuit operates at a lower pressure than the main circuit of the nuclear power plant and the circuit that transfers heat to the desalination plant.…”

Small modular reactors (SMRs) represent a key area of interest to nuclear industry developers, which have been making significant progress during the past few years. Generally, these reactors are promising owing to their improved safety due to passive systems, enhanced containment efficiency, and fewer capital costs in comparison to traditional nuclear reactors. An important advantage of SMRs is their adaptability in being coupled to other energy-consuming systems, such as desalination plants (DPs) to create a cogeneration plant. Considering the serious challenges regarding the freshwater shortage in many regions of the world and the necessity of using low-carbon energy sources, it is advantageous to use SMR for supplying the required heat and electricity of DPs. As a high-performance desalination technology, the hybrid desalination (HD) systems can be exploited, which retain the advantages of both thermal and membrane desalination methods. In this study, several SMR coupling schemes to HD plants have been suggested. In performing a thermodynamic analysis of integrated SMR-DP, the International Atomic Energy Agency (IAEA) Desalination Thermodynamic Optimization Program (DE-TOP) has been utilized. It has been found that the use of relatively hot water from the SMR condenser leads to about 6.5 to 7.5% of total desalination cost reduction, where the produced electricity and hot steam extracted from low-pressure turbine were used to drive the HD system.
