“…In the competition with internal combustion engines, gas turbines (GTs) and steam turbines with boilers have had no competitive advantages in merchant marine propulsion due to their lower fuel economy. Although there are a large number of advantages of nuclear-powered marine propulsion (Hirdaris et al, 2014), such as no exhaust gas emissions, no frequent refuelling required and higher power generation, low public acceptance (Schøyen and Steger-Jensen, 2017) and low cost-effectiveness (Freire and de Andrade, 2015) restrict the potential for widespread use. Between 1-32% energy substitution for wind-assistance (Balcombe et al, 2019;Halim et al, 2018) and 0.2-12% energy substitution for photovoltaic systems (Bouman et al, 2017) are claimed to be achievable.…”

This work aims to present the historical context in which the current understanding of the phenomenon of the direct contact condensation started to call the scientific society attention. The development of nuclear power plants Light Water Reactors demanded a safe way to collect and treat the water used to cool the reactor. Some characteristics of this water in a high energetic thermodynamic state made it unsuitable to be directly discharged in the atmosphere. Small room relieves tanks were developed to contain this discharge. These tanks were partially fulfilled with water, and the vapor injection created a vapor plume. In the interface of liquid and vapor, the thermal exchange would be increased by the characteristic turbulence of this region.

MicroURANUS : Core design for long‐cycle lead‐bismuth‐cooled fast reactor for marine applications

et al. 2021

Summary A core design of MicroURANUS, a long‐cycle lead‐bismuth‐cooled fast nuclear reactor for marine applications, is presented. It aims to generate a power of 60MWth, which can be regulated during operation. MicroURANUS was designed to achieve a small burnup reactivity swing for 30 effective full‐power years of a lifetime without refueling. To attain these goals, a unit cell study with uranium oxide fuel was initiated to lay a solid foundation for core design, owing to size constraints. A reflector optimization was also performed to minimize neutron leakage. MicroURANUS adopts onion zoning constructed by two enrichment zones for flattening the power and lengthening the core lifetime. The coolant is driven by electromagnetic pumps to achieve inlet and outlet temperatures of 250°C and 350°C, respectively. MicroURANUS analyses were performed using the Argonne Reactor Computation suite and the Monte Carlo code MCS. Core performance features were analyzed for criticality, power profiles, fuel isotope mass inventory, reflector coefficients, reactivity feedback coefficients, and shutdown margin. Additional thermal‐hydraulic calculations were performed to confirm that the fuel and cladding temperatures were within the acceptable range. Furthermore, a load follow analysis using the quasi‐static reactivity balance method confirmed the feasibility of regulating power by adjusting the inlet coolant temperature.
