Breeding blankets are critical fusion plant components that harvest energy from the reactor while generating tritium fuel by bombarding liquid lithium with neutrons. Unity-3 will test multiple breeding blanket materials and provide experimental validation data for fusion startups including Realta Fusion, Thea Energy, Type One Energy, and Xcimer Energy. The company is also relocating its U.S. headquarters to Oak Ridge. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### What is a breeding blanket in a fusion power plant and how does it work? A breeding blanket is a fusion reactor component that serves two purposes simultaneously: it harvests energy from the reactor and generates fresh tritium fuel. One design uses liquid lithium, which absorbs heat and neutrons. When lithium atoms are bombarded with neutrons, they split into helium and tritium — a hydrogen isotope used as fusion fuel. The tritium is separated and fed back to the reactor, while extracted heat generates electricity. _Engineers working on fusion plant design track breeding blanket developments like Unity-3 on daily.dev._ ### How much funding has Kyoto Fusioneering raised? Kyoto Fusioneering has raised $121 million in committed capital, according to FusionX. The Japan-based company has also secured grants from the U.S. Department of Energy and the state of Tennessee to build a prototype breeding blanket device called Unity-3 at Oak Ridge National Laboratory, where it is also relocating its U.S. headquarters. _Those following fusion energy investment and supply chain news find the latest rounds covered on daily.dev._ ## Similar posts on daily.dev - [Google DeepMind alumni are building tools to accelerate fusion power for the grid](https://daily.dev/posts/google-deepmind-alumni-are-building-tools-to-accelerate-fusion-power-for-the-grid-0l4m2unju) · TechCrunch · 0 upvotes · 0 comments - [The race to build a star on Earth](https://daily.dev/posts/the-race-to-build-a-star-on-earth-tcceissoh) · TechCentral · 0 upvotes · 0 comments - [University Of Utah’s TRIGA Research Reactor Set To Produce Electricity](https://daily.dev/posts/university-of-utah-s-triga-research-reactor-set-to-produce-electricity-xhowzyixw) · Hackaday · 0 upvotes · 0 comments - [Terra Fusion Builds Magnetic Mirror Fusion Reactor](https://daily.dev/posts/terra-fusion-builds-magnetic-mirror-fusion-reactor-4bsdgyfh4) · IEEE Spectrum · 0 upvotes · 0 comments --- [View this post on daily.dev](https://daily.dev/posts/kyoto-fusioneering-starts-work-on-key-fusion-power-plant-device-aghanxg6d) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"Kyoto Fusioneering starts work on key fusion power plant device","url":"https://daily.dev/posts/kyoto-fusioneering-starts-work-on-key-fusion-power-plant-device-aghanxg6d","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/kyoto-fusioneering-starts-work-on-key-fusion-power-plant-device-aghanxg6d"},"datePublished":"2026-08-11T15:04:07.490Z","dateModified":"2026-08-11T15:04:39.242Z","description":"Kyoto Fusioneering, a Japan-based fusion supply chain startup with $121M in committed capital, has received grants from the U.S. Department of Energy and the...","image":"https://media.daily.dev/image/upload/f_auto,q_auto/v1/posts/4873cfe577b23724f321bbb7d84ad35a?_a=AQAEuop","thumbnailUrl":"https://media.daily.dev/image/upload/f_auto,q_auto/v1/posts/4873cfe577b23724f321bbb7d84ad35a?_a=AQAEuop","isAccessibleForFree":true,"articleSection":"TechCrunch","inLanguage":"en","publisher":{"@type":"Organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180}},"author":{"@type":"Organization","name":"TechCrunch","logo":"https://media.daily.dev/image/upload/t_logo,f_auto/v1/logos/tc","url":"https://daily.dev/sources/tc"},"commentCount":0,"discussionUrl":"https://daily.dev/posts/kyoto-fusioneering-starts-work-on-key-fusion-power-plant-device-aghanxg6d","interactionStatistic":[{"@type":"InteractionCounter","interactionType":{"@type":"LikeAction"},"userInteractionCount":0},{"@type":"InteractionCounter","interactionType":{"@type":"CommentAction"},"userInteractionCount":0}],"keywords":"","timeRequired":"PT3M"} {"@context":"https://schema.org","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"name":"Home","item":"https://daily.dev"},{"@type":"ListItem","position":2,"name":"TechCrunch","item":"https://daily.dev/sources/tc"},{"@type":"ListItem","position":3,"name":"Kyoto Fusioneering starts work on key fusion power plant device"}]} {"@context":"https://schema.org","@type":"FAQPage","@id":"https://daily.dev/posts/kyoto-fusioneering-starts-work-on-key-fusion-power-plant-device-aghanxg6d#faq","mainEntity":[{"@type":"Question","name":"What is a breeding blanket in a fusion power plant and how does it work?","acceptedAnswer":{"@type":"Answer","text":"A breeding blanket is a fusion reactor component that serves two purposes simultaneously: it harvests energy from the reactor and generates fresh tritium fuel.
