The Westinghouse eVinci is supposed to use heat pipes and a Brayton cycle, so they would actually be water-free.

I don't think that is what Valar has in mind.

eVinci sets temperature record during zero-power criticality tests
Westinghouse says the completion of zero-power high-temperature criticality testing for the microreactor, which saw it reach criticality at 663 degrees Celsius, is a defining milestone in the programme's build-test-learn development journey.  ;

[some-subscribed-rss] New Post: Westinghouse eVinci Microreactor Achieves Criticality Milestone, by Energy.gov https://www.energy.gov/ne/articles/westinghouse-evinci-microreactor-achieves-criticality-milestone
Teaser: Westinghouse has hit a major milestone with its eVinci microreactor, successfully completing criticality testing at the National Critical Experiments Research Center in Nevada. The test reached criticality at 663 degrees Celsius, pushing the heat-pipe-cooled, TRISO-fueled design closer to real-world deployment. Designed to produce 5 megawatts of electricity on sites as small as two acres, the commercial version aims to run eight or more years without refueling. The data from these experiments will sharpen analytical models and accelerate prototype development, with potential applications including powering U.S. military installations. But the road from test bed to deployment is far from over—read on to see what this breakthrough means for the future of advanced nuclear energy. teaser for https://www.energy.gov/ne/articles/westinghouse-evinci-microreactor-achieves-criticality-milestone generated by deepseek/deepseek-v4-flash

Five advanced reactors hit criticality in the last ten weeks: Antares Mark-0, ZiaCore, Aalo, Radiant, Oklo Groves. Now Westinghouse's #eVinci joins them. American nuclear shifted from "will these work?" to "how fast can we build them?"

NOTE - "EXPERIMENTING" 👆
The micro-nuclear reactor: realistic or just an expensive hobby?
COLUMN – The nuclear energy hype is back, and this time it’s mainly in miniature form. Modular reactors (SMRs) and even microreactors ranging from 5 to 30 MW are set to supply industry, data centres and remote locations with reliable, low-carbon electricity.

Westinghouse приключи тестовете за критичност на своя микрореактор “eVinci” – целта е 8 години непрекъсната работа
Westinghouse приключи тестовете за критичност при нулева мощност на своя микрореактор „eVinci“, като по този начин потвърди валидността на моделите за проектиране на ядрото му. Изпитването беше проведено на 24 август в Националния изследователски център за експерименти по критичност (NCERC) - обект на Националната администрация за ядрена сигурност, намиращ се в Националния обект за сигурност в Невада. Националната лаборатория „Лос Аламос“ и Националната лаборатория „Айдахо“ сътрудничиха на Westinghouse при провеждането на изпитването. Изпитването не е генерирало електроенергия. Вместо това тестовете за критичност при нулева мощност позволяват на инженерите да изследват ядреното поведение на ядрото на реактора, без да го експлоатират на пълна мощност.

Micro nuclear reactors?. How about nuclear power cells - like the one powering the T-800s?
Micro nuclear reactors are being built that can deliver 5MW of power for up to 100 months, producing a staggering 1.2 petawatt-hours of energy
Westinghouse says its eVinci microreactor could power future data centers, and even be used on the moon
