Core Insights - The nuclear renaissance presents significant investment opportunities in advanced electricity production technologies, particularly through companies like Westinghouse and Oklo [1] Westinghouse - Westinghouse, partially owned by Cameco Corporation (CCJ), is a major reactor developer with three designs: AP1000, AP300, and eVinci [1] - The AP1000 is a large, pressurized light water reactor with over 1,000 megawatts capacity, featuring Gen III+ technology and passive safety systems [1] - Construction of AP1000 reactors has faced challenges, including delays and cost overruns, but two units at the Vogtle site were completed, while two others at VC Summer were abandoned mid-construction [1] - The AP300 is a smaller version of the AP1000, with a capacity of about 300 megawatts, designed for smaller electrical grids [1] - The eVinci microreactor, with a capacity of 5 megawatts, utilizes Gen IV technology and advanced fuel materials, targeting unique applications like remote mining operations [1] - Westinghouse also has a significant presence in the nuclear fuel chain and is a major uranium producer through Cameco's projects in Canada [1] Oklo - Oklo has three distinct reactor designs, including the Aurora sodium reactor, which operates with liquid sodium for improved heat transfer and passive cooling, with a capacity of 75 megawatts [1] - The second design, developed by Atomic Alchemy, is similar to research reactors and focuses on producing isotopes for medical and defense applications rather than electricity generation [1] - The Pluto reactor, which uses plutonium fuel, is designed to complement Oklo's nuclear fuel recycling technology, although specific details on its capacity are limited [1] - Oklo is also developing in-house fuel fabrication capabilities for liquid metal cooling reactors [1] Investment Index - Both Westinghouse and Oklo are constituents of the VettaFi Nuclear Renaissance Index (NUKZX), which tracks companies involved in the nuclear sector [2]
