I think it depends on what you call the reactor. I think of a reactor as the vessel that holds the fuel, moderator, controls, etc. From the NRX diagram, the reactor includes everything within the concrete "biological shield". H

Abba has always been the guilty pleasure that I'd never admit to my musician friends. Have to confess that I like their new song “I Still Have Faith In You”.

Both Pfizer and Moderna have stated that boosters will be needed this Fall. Pfizer says that immunity drops from 96% to 84% at the six month point. The good news is that the vaccine continues to protect against severe disease due to its e

You're right about HN. Experts in all domains. My experience is from the Vietnam era and doesn't apply today. I was drafted mid-way through an EE program when I got behind in units. Virtually all of us had similar backgrounds.

Oxygen generators use electricity (electrolysis), not steam. Thankfully, we never had to use oxygen candles. Candles are effective only in a small closed space. That would have been a serious emergency.

Yes. Subs use low-pressure steam to desalinate sea water. Having lots of fresh water for showers was a huge benefit of nuc boats over diesel boats.

Is this contraption actually a robot? A robot has some automatic function or autonomy. I would classify this thing as a coconut harvesting machine.

Doubt if an 8008 uC would have been a commercial success. It ran at 125 KHz with instructions taking around 20 clocks. Instruction set was very primitive compared to the 8080 and the address bus was only 14 bits wide. It was best suited
