Sustainability; A mobile energy supply unit based on a lead-bismuth-cooled, small modular fast reactor called SUstainable Modular Mobile Enhanced Reactor. This chapter describes fast neutron reactors that use one of the two so-called Heavy Liquid Metal Coolants, namely lead Pb and lead-bismuth eutectic LBE, both. The lead-bismuth cooled fast reactor eliminates the need for large high-pressure vessels, has simple auxiliary systems and has low construction, operation and maintenance costs. The research and small modular lead-cooled fast reactor SMLFR is characterized by high safety, high efficiency, adaptability and versatility. The integrated system design adapts to site conditions. Cogeneration is an advanced form of energy use, based on the principle of energy cascade use, where energy is mainly used for production. An innovative small transportable lead-bismuth cooled fast reactor called SPARK with a rated power in MWth is proposed to operate for years without refueling as a remote power supply. The SPARK core neutronics and thermal-hydraulic design and preliminary safety analysis were carried out in the present study. An innovative lead-bismuth eutectic LBE-cooled ultra-long life fast reactor, called MicroURANUS, is designed to prevent serious accidents. It uses the remarkable natural circulation ability. The lead-cooled fast reactor LFR has a fast neutron spectrum, operation at high temperatures and cooling by molten lead or lead-bismuth eutectic LBE, low pressure, chemically inert fluids with very good thermodynamic properties. It would have multiple applications, including the production of electricity, hydrogen and process heat.1. Introduction. As one of the typical nuclear systems of Generation IV (Kelly, 2014), the lead-cooled fast reactor has been widely concerned by numerous researchers, attributed to the corresponding advantages of low operating pressure, significant neutron consumption and high exhaust temperature, namely the high thermal parameter of secondary- One of the ways to find the solution to the problem is the use of modular fast reactors cooled by lead-bismuth coolant developed in the conditions of operating reactors of Russian nuclear submarines. Based on this experience, the fast reactor with small power for multifunctional use SVBR-75 100 was developed. Lead-based fast reactors LFRs have unique advantages in SMR development, which has attracted much attention in recent years. In this paper, an optimized design for a small modular lead-bismuth reactor based on the SUPERSTAR design was studied. This paper aims to propose an improved LFR core scheme. A core design of MicroURANUS, a long-cycle lead-bismuth-cooled fast nuclear reactor for maritime applications, is presented. It has to,
