Explore the sustainable world of nuclear power including conventional, Small Modular Reactor (SMR), General IV and fusion technologies. Focus primarily on SMR’s and their integration with Gen IV power systems including Gas-cooled Fast Reactor (GFR), Lead-cooled Fast Reactor (LFR), Molten Salt Reactor (SFR), and Very High Temperature Reactor (VHTR). Examine sustainability and economic goals that reduce GHG emissions, provide stability, and responsibly manage waste, while providing safe, cost effective, and secure energy generation. Distinguish how advanced nuclear can work with renewable energy generation to create resilient energy networks.
