# Compact Steam Generator Designs Apollo Atomics Unveiled Its Miniaturized Steam Generator By Adam Harrie | Written with AI assistance | Published 2026-08-28 | Tech Source: Trend Hunter, https://www.trendhunter.com/trends/apollo-atomics References: [techcrunch](https://techcrunch.com/2026/08/20/apollo-atomics-wants-to-make-nuclear-power-cheaper-by-shrinking-an-overlooked-part/)  Apollo Atomics introduced a compact steam generator designed to shrink one of a nuclear reactor’s largest components and make power plants substantially smaller. The Y Combinator-backed startup uses a metal block containing needle-thin channels that carry reactor coolant and steam loops, producing a steam generator roughly the size of a person. The company says the design can replace hand-built, multistory steam generators with factory-manufactured modules that improve heat transfer and support [modular assembly](https://www.trendhunter.com/trends/pmt-critical-metals). Apollo has already demonstrated the approach with a 40-kilowatt reactor developed with MIT and recently raised $26 million in seed financing. It plans commercial deployment beginning in 2028, with reactor sizes ranging from 10 MWe to 300 MWe. For grid operators, the smaller factory-built system could reduce construction time, labor and capital costs, positioning [thermal conversion efficiency](https://www.trendhunter.com/trends/thermal-storage-system) as a key lever in making [advanced nuclear power](https://www.trendhunter.com/trends/commercial-nuclear-reactors) more competitive.
