It is a full-scale replica of microreactor, which is 12 feet tall and weighs 2,000 pounds. The firm’s expertise is in alkali metals.ĬEI installed the PCAT into a two-story frame and where it will be loaded with sodium-potassium and lead-bismuth coolants. It was then loaded onto a truck and transported from INL to Creative Engineers Inc (CEI)’s manufacturing facility in New Freedom, Pennsylvania. INL built the full-scale, electrically heated prototype, known as the primary coolant apparatus test or PCAT, last year. Marvel is currently in Final Design Phase, with 90% construction planned to conclude in in 2023, and fuel load and initial criticality in 2024. Off-the-shelf Stirling engines will convert thermal energy to 20 kw electrical power. The reactor will be a sodium-potassium cooled reactor with natural circulation cooling and and operating temperature of 500-550C. DOE has completed an environmental impact statement on the project. To speed up deployment, Marvel will be established in INL’s Transient Reactor Test (Treat) Facility making use of existing operating Category B reactor facility, approved facility safety basis, operating crews, and recent re-start experience. The microreactor design is a thermal reactor that will use uranium zirconium hydride fuel ( Technical Paper on UZrH).
#WE NEED TO GO DEEPER TIME TRAVELER LICENSE#
The outcome of this scope of work will be of particular interest to developers of microreactors especially those who want to license the open source design data of the Marvel Reactor for scaled-up versions. Eventually, INL expects to be in a position to offer non-exclusive licensing of the reactor design to firms that wanted to use it to develop commercial versions.Īnother applied R&D focus is to address challenges related to fabrication of microreactor components, assembly of systems, rapid installation at customer sites, and other measures to facilitate end-user adoption. The DOE Microreactor Program supports research and development (R&D) of technologies related to the development, demonstration, and deployment of very small, factory-fabricated, transportable reactors to provide power and heat for decentralized generation in civilian, industrial, and DOE uses.Ī key focus of the program is engagement and outreach with end users and stakeholders to perform R&D on integration of microreactors with a range of anticipated applications including load-following electricity demand, process heat, hydrogen production, and water purification. It will also allow microreactor technologists to test next-generation control systems. The object of building and operating Marvel is to establish a fully functional nuclear applications test bed that can generate combined heat and power to enable integration and R&D with end-user technologies. The Marvel project goal is to provide a 100 kw fission reactor for researchers and technology developers to gain operational experience with a real microreactor and to advance technological maturity for reactors at this scale, and to enable new microreactor applications.
The Microreactor Applications Research Validation & Evaluation (Marvel) Project covers the design, development, construction, and start-up of an INL test microreactor, funded by the Department of Energy through the Microreactor Program (MRP). The Marvel micro-reactor will be the first new test reactor to be built at Idaho National Laboratory (INL) in more than four decades.
