Meltdown in the comments
Wi-Fi That Can Withstand a Nuclear Reactor: This receiver chip can take it
Nuke‑proof Wi‑Fi sparks cheers, eye‑rolls, and roof‑router jokes
TLDR: A new Wi‑Fi receiver reportedly survives reactor‑level radiation, promising safer, cable‑free robots for nuclear cleanup. The comments split between hype and hard reality: jokers meme the “roof router,” veterans warn that radiation shreds electronics, and pragmatists say this could still shine in less extreme areas—safety gains if it works.
A Tokyo research team says they built a Wi‑Fi receiver that shrugs off nuclear‑reactor radiation, surviving a dose that would roast most space electronics. The goal: cut the tangle of cables on cleanup robots and make decommissioning safer after disasters like Fukushima. Presented at ISSCC, the chip reportedly withstood a mind‑bending 500 kilograys—think “thousands of times tougher than space gear.”
Cue the comments: half applause, half side‑eye. One joker deadpanned, “You didn’t see Wi‑Fi on the roof,” turning the breakthrough into a meme about hiding routers in apocalyptic places. A field‑hardened voice chimed in with a reality check: cameras near “hot” fuel sometimes lasted 24–48 hours before the image turned into a “confetti party,” and even video encoders choked—translation: the reactor’s neighborhood is where electronics go to die. Another commenter pointed to ITER’s robots that use hydraulics only, not electronics, as a hard‑line “no chips near the core” philosophy.
Fans of the research say it’s still huge for the “warm zones” of a plant, where line‑of‑sight links could free robots from snag‑happy cables. Skeptics counter that radiation is a relentless bully and real‑world interference will humble any chip. Either way, the thread’s verdict is classic internet: big science win, bigger memes, and a looming showdown between Wi‑Fi wizards and hydraulic die‑hards.
Key Points
- •A 2.4 GHz Wi‑Fi receiver survived a total radiation dose of 500 kGy, far exceeding typical space electronics tolerances.
- •The receiver is intended to enable wireless control of robots for nuclear reactor decommissioning, reducing reliance on LAN cables.
- •Presented by Yasuto Narukiyo (Institute of Science Tokyo) at ISSCC in San Francisco, the work involved collaborations with KEK.
- •Design strategies included minimizing transistor count, using longer/wider MOSFET gates, and reducing PMOS usage in favor of inductors and NMOS.
- •Testing measured performance before irradiation and after 300 kGy and 500 kGy doses; pre-irradiation performance matched typical Wi‑Fi receivers.
