Small modular reactors installed in single or multi-unit power plants make it possible to combine nuclear and alternative energy sources, including renewable sources.<br>However, the problem of optimal choice of the type of coolant for such reactors remains unresolved. Despite the seemingly obvious choice, the use of water as a coolant carries significant risks of a heat transfer crisis in the core in emergency situations, and the possibility of an exothermic zirconium vapor reaction has led to catastrophic consequences at the Fukushima-Daiichi NPP [1]. The use of gas, organic heat transfer fluids or salts causes no less problems and risks. Liquid metal coolant &#8211; liquid sodium requires special care in handling it due to its fire and explosion hazard, and the use of a lead-bismuth coolant leads to the formation of a large amount of hazardous radioactive polonium-210, which, in case of accidents with depressurization, can escape into the environment and lead to serious radiation consequences in the adjacent territories. Therefore, perhaps the most acceptable coolant option for small-sized modular reactors may be ordinary lead.<br><span class=\"has-inline-color has-white-color\">.<\/span><br><a rel=\"noreferrer noopener\" href=\"https:\/\/www.journal-of-nuclear-physics.com\/files\/Low-power modular lead-cooled nuclear reactor.pdf\" target=\"_blank\">Read the whole article<\/a><br><a rel=\"noreferrer noopener\" href=\"https:\/\/www.journal-of-nuclear-physics.com\/files\/Low-power modular lead-cooled nuclear reactor.zip\" target=\"_blank\">Download the ZIP file<\/a><br><span class=\"has-inline-color has-white-color\">.<\/span><\/p>\n","protected":false},"excerpt":{"rendered":"\n<p class=\"has-text-align-right\">.byVitaly Uzikov, Lead Ingeeneer, JSC \u201cSSC RIAR\u201d (Russian Federation)Irina Uzikova, Nuclear Safety Engineer, Assystem E&amp;OS (France).<\/p>\n<p>Read the whole articleDownload the ZIP file.<\/p>\n<p>IntroductionOne of the main directions of modern development of nuclear energy is the creation of small modular reactors.
