“…The negative value of the variable (Q i hs ) models the charging time, and the positive value determines the discharging mode. The charging and discharging power should not exceed the maximum hourly rates (RR ch hs , RR dch hs ), respectively, according to (33). The variable (SE i hs ) represents the stored thermal energy at each hour (i), which should satisfy the energy balance as formulated in (34) and (35).…”

Carbon-free thermally driven district cooling systems (DCS) can effectively mitigate the excessive electricity consumption and carbon emissions associated with the cooling sector. This study proposes a DCS that employs nuclear heat as the primary energy source. The system comprises three main subsystems: heat station, heat transmission, and cooling station. A heat-only small modular reactor called Teplator, gas boilers, and heat storage are considered to supply the heat required to drive absorption chillers; cold storage and compression chillers are the supplementary units. The technoeconomic aspects of the system are formulated, and an algorithm is developed to determine the optimal design and operation. The method is examined for supplying a typical cooling demand profile with a peak of 2050 MWc. The resulting optimized design includes 11 nuclear plants (150 MWt each), 20 000 MWth heat storage, and 1.9 m diameter heat supply/return pipes. Absorption chillers with a total capacity of 1424 MWc are determined, covering 92% of the total cooling demand, and 244 MWc of compression chillers and 20 000 MWch of cold storage are found to cover the peak and enhance the load following. This system saved 69% of the electricity consumption and carbon emissions and 34% of the costs compared with an electric-based scenario.

“…In the Czech Republic, the TEPLATOR project proposes to use spent PWR fuel bundles in a tank for the express supply of district heat at 98°C, and although it is not a homogenous design, and runs on spent fuel, the low capital cost of constructing such simple reactors may allow TEPLATOR to deliver heat at prices significantly lower than with fossil fuels [11]. A purpose-built AHR for such a purpose could, in theory, be able to do the same, if not more effectively.…”

Nuclear Fission - From Fundamentals to Applications

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.

This paper was written after the beginning of the 2022 energy and security crisis in Europe, which forced the national state governments as well as the European Union (EU) to reexamine environmental and energy strategies. The paper focuses on the role that small modular reactors (SMRs) may play as a part of a medium and long-term solution to this unprecedented situation. The history of EU climate policies and the current energy situation in the EU is broadly examined. The paper explores the potential energy, national security, and environmental benefits of nuclear power, along with its possible contribution to a net-zero economy. The main focus of the study, involving discussions with experts in the United States (US), was on the development of SMR-specific regulations, as well as the progress of SMR deployment projects in the US. The discussion explores SMR deployment challenges and potential solutions, in terms of policy recommendations applicable for the EU and its member states, in case a rapid SMR deployment becomes politically desirable.
