I would love to use RSS to disseminate updates I’m working on, especially to my family. But my family wouldn’t know what RSS was, let alone use a reader. Are there ways my family could already be using RSS and not know? I don’t want to try to get them to install yet another app or use another service because the friction will prevent them from doing it.
This is very interesting to me because a plant this old might be cheaper to operate than a new plant, but might be like the space shuttle in that replacement parts aren’t readily available and thus expensive to custom manufacture.
If you were to step into the control room you’d see analog phones, tiny incandescent bulbs behind plastic covers… looks like a sci-fi set from the 60s.
The expensive part of a reactor isn’t really the reactor or tech itself, it’s the government regulation from the DOE and NRC.
I worked at Areva/Framatome/B&W and IIRC they still have the archival room where hundreds of 4 inch D ring binders held the original design docs that had to be submitted for approval.
Not too disagree with the bulk of comment, but this sentence is not true. They're 90V neon indicator lamps, a technology that's really cool but also so inefficient that people rip it out and replace it.
We absolutely need rinse aid here, even with a water softener. But we make our own with ethanol and citric acid. For us works just as well as the pricey stuff and costs us…. A large bottom shelf bottle of vodka (sorry, don’t drink and don’t buy this enough to remember) and about $0.50 in citric acid will last me 6 months.
Yeah, I have very soft water. I tried using a liquid rinse aid when I switched from a name brand pod with a rinse aid to the cheap Kirkland pods. The rinse aid made things worse and I did end up with a residue on my glassware.
It’s cheap enough to try it and see if it helps but don’t feel obligated to use it if it doesn’t.
I ordered citric acid off of Amazon (it’s great at getting out hard water stains in bathrooms and toilets and helps keep my water softener going well (I add some to the salt tank), also can add some good kick to lemonade)
For every cup of vodka (40 or 60% can’t remember, but prolly 40. Though scientifically 60% would be better) I add 1 to 2 tsp of powdered citric acid. Takes a surprisingly long time to dissolve so you’ll get a quick workout shaking it. I’ve added blue food coloring before to make it more visible in the dispenser to see the level but it’s not necessary at all so I usually skip it.
I make it in a 1 liter bottle which will last a couple months. We have a Bosch dishwasher, refill it… every couple of weeks maybe? I’m not the only one filling it. We do 1-2 loads of dishes a day (4 kids who can’t ever seem to find the cup they JUST used. Probably a parenting problem)
I have no idea if that’s helpful. But I did just lookup a cost by fluid volume- I live in a state with high alcohol tax rates and my cost per fluid oz of my DIY rinse aid is around $0.19 (mostly from alcohol, per fluid oz of citric acid is less than one cent. ) for reference, the small bottle of Jet-dry is $0.58/flOz.
Not sure I understand your point, but if it’s helpful, I’m blind, prefer to be called blind, but get tired of educating people on what “blind” actually means as it’s a spectrum and not a binary condition.
In my community we refer to non-blind people as “sighted” which I suppose is also a spectrum.
Blind is very descriptive, and in my opinion not derogatory. I’d rather it not be my primary differentiator or descriptor unless comparing me to virtually identical people who have full or near full vision. “The blind engineer on the team” is ok with me as it’s the fastest way to describe me if we’re all middle aged guys with beards. If I’m the only bearded guy on the team of middle aged engineers I’d prefer “the engineer with a beard”
> A fighter jet and a helicopter based off the aircraft carrier USS Nimitz both crashed into the South China Sea within 30 minutes of each other, the Navy’s Pacific Fleet said.
>The three crew members of the MH-60R Sea Hawk helicopter were rescued on Sunday afternoon, and the two aviators in the F/A-18F Super Hornet fighter jet ejected and were recovered safely, and all five “are safe and in stable condition,” the fleet said in a statement.
>The causes of the two crashes were under investigation, the statement said.
Yes* most of the time. The purpose is the Pentagon doesn't want adversaries or anyone else getting their hands on classified gear or aircraft systems because it's basically flying around with a datacenter nowadays. If it's in deep water, NAVSEA may bust out FADOSS gear and make it a OJT exercise for junior recovery personnel.
Even if nothing was damaged (like that's going to happen) after you fish them out of the drink you think they can be put back in service? Just look at the boosters on the Shuttle--the cost to refurbish them after their dip in the ocean was almost as much as buying new. Valuable in as much as it showed the problem that lead to Challenger, but they refused to look.
Chlorinating the water would have adverse effects on material strength and longevity. Even irradiated and heated to 50c, I’ll bet there’s some extremophile bacteria in there somewhere.
Had a buddy on a nuclear sub drink water from the primary coolant loop when he joined the team.
While I do see this as a form of hazing which I am morally opposed to-
8oz (.237 liters) of primary coolant in a properly maintained pressurized water reactor might contain up to 13mrem of orally ingestible radiation, or approximately the radiation of a chest x-ray. (For comparison you get between 3-8 milirem on a 7 hour transatlantic flight)
Don’t make it your primary source of hydration and you’ll be ok. If the fuel is degraded or there is a leak (unlikely in properly maintained PWRs) the radiation dose is significantly higher.
That makes zero sense. Radiation is not a component of water; it is literally photons[0]. In the nanosecond after you fill the glass, all the radiation in it has left the volume.
I'd drink it. It's just extremely pure water, with a nuclear flashlight at the bottom of the pool - which no one could see, even if they had gamma-ray glasses on[1], because the water attenuates it so much.
[0] Or ions of hydrogen or helium, in the case of alpha and beta radiation.
[1] Which it turns out were way less cool than the Sea Monkeys(tm).
Radiation isn’t contained in the water as photons, but the coolant itself becomes radioactive through neutron activation. Even with intact fuel rods, oxygen in the water turns into N-16 with a half-life of about seven seconds, and trace metals like nickel and cobalt form isotopes such as Co-58 and Co-60. These emit strong gamma radiation while the reactor operates.
The primary coolant is not simply pure water; it contains boric acid, lithium hydroxide, dissolved hydrogen, and trace corrosion products like iron, nickel, cobalt, and chromium. Under power level neutron flux, some of these elements become short- or medium-lived radionuclides. Once removed from the core, most of the activity decays within minutes, but during operation the water is measurably radioactive.
An eight-ounce sample taken from the loop at power would carry roughly the dose of a chest X-ray before it decayed away, due to these activated isotopes rather than residual photons [EPRI PWR Primary Water Chemistry Guidelines; NUREG-1437][0].
I was on site for the mid cycle outage of three mile island unit 1 around 2005. I did the data sync and transfer for the steam generator inspection, but got tutored by some old PHDs during the down time.
