They need this. Dominion has a significant number of older (built in late '50's and early '60's) coal fired plants, which are all being shut down over the next couple of years because they cannot be brought up to a high enough standard to meet the new EPA requirements. They are also shutting down an 800 MWe oil fired unit built in the 1970s, because of the new EPA requirements and because it's not very economical to operate any more (it was only being used for peaking and to supply base load if one of the nuclear plants was shut down for service). We already depend on those nuclear plants for base load and we will be leaning on them more in the future
Dominion submitted an application to add a third reactor to the North Anna site in 2007. It's been in review since then. As I understand it, the plan is to put in a third generation ESBWR that will nearly double the North Anna site's output. The reactor design was finally approved late 2014. Hopefully they'll get site approval to start construction soon.
The rumor is, the rights for OS/2 are partially owned by Microsoft, and they won't agree to make it open source. Unless something changes, projects like this one make no sense.
That's not really a rumor. It was originally a joint project, until there was a disagreement and a splitting of ways. IBM continued on with a release as OS/2 and Microsoft released the "New Technology" NT kernel. There's likely joint ownership on a lot of the original kernel code.
I call Amex before I travel. It's just a good idea to let them know in advance. Same is true for my Capital One card, I call them before I travel. That way I'm not standing in an airport, on the phone, trying to convince them that, yes, it really is me, when I'm trying to pay my bar tab.
Ancient? I've got a Pentium D 805 running as a general family use machine and a Pentium III running as a file server. I just got rid of a bunch of Pentium (as in the original) boards year. I have an 8080 I pulled from an old board, framed, hanging in my workshop. Now get off my lawn.
PLA is biodegradable... That means it won't last very long if he is released. Certainly not long enough for an animal whose normal life expectancy is several decades.
My children have to enter a PIN when they buy there lunch. Extra charges are always showing up on our account because other kids can't remember their pin or mis-type it and there's no check. This way, with the biometrics, the charges (OK, the article is talking about free lunches...) would end up on the correct account.
No, no they're not. They had the option to build them and they decided it would be too expensive to tool up. Instead, they continue to purchase the engines from NPO Energomash. What you might be thinking of is the NK-33's being refurbished into AJ-26 engines for the Antares rocket used by Orbital; at least until one blew up a few seconds after launch in Virginia in 2013.
ALL power plants require external power for cooling once they're tripped. In big plants like that, if you don't shut the system down correctly and cool the boiler off in a controlled fashion, you're going to cause all kinds of damage. This can include catastrophic failure of the boiler. Only difference is a coal fired boiler doesn't contain nuclear fuel and radioisotopes.
Fukushima was a cluster fuck. American plants apparently have more redundancy on the emergency generators than Japan requires. In addition, there are emergency cooling systems, even in the older designs, that use (for example) the steam generated by the plant itself to turn pumps. In Japan, they'd never tested those systems; so, didn't know if they were working or not (they were not).
I would like to see the plants all upgraded to newer designs myself but that's going to take decades; and, in the current societal and political climate may not happen.
What you're describing is true of any power plant, disconnect the load and you have to stop feeding the turbine and dump the steam or you'll destroy the generator and turbine. This is a standard capability built into any plant, coal, gas, or nuclear. The gotcha is in shutting down the reactor, which can take longer to bring up than a coal plant -- which takes 1/2 day instead of several days.
This story is being way overblown. Yes, it's a bug. Yes, it should be fixed. However...
248 days of continuous operation is well past the scheduled major maintenance for the aircraft. By this point, a 787 would have to go through many minor maintenance cycles which would have required shutting down the electrical system. In addition, loss of all 4 generators would not result in a loss of vehicle because there are batteries, an APU (a backup generator) and Ram Air Turbines (RATs), generators that deploy from the wing if the APU won't start. To have to rely on any of these would not make for a good day for the pilots; but, they would certainly provide the necessary power to safely land the aircraft at the nearest airport. They might even be able to continue on and finish their flight if they successfully reset the generators.
This is not the OMG Planes Are Going to Fall From The Sky! event the media is making it out to be.
If it ever happened on a plane, then it means that the maintenance was intentionally skipped. If they reach 248 days of continuous operation then a number of significant maintenance cycles have been skipped (some 23-25 inspection / maintenance cycles that generally require shutting down the electrical system). The generators in question are attached to the engines. The engines have a overhaul schedule that is shorter than 248 days of continuous operation. If they managed to reach this point, then the major maintenance cycles have been skipped and the engines are long overdue for a tear down inspection and overhaul. Any plane which could reach this point, 248 days of continuous operation missing all of the required maintenance; this is not a plane (or an airline for that matter) which anyone should be flying on.
So perhaps the astronauts shouldn't spend all their time standing naked out on the airless surface of Mars, letting the universe blast their noggins with relativistic oxygen and titanium ions (yes, I read the article). If you don't want to get wet, you have to come in out of the rain.
Good for them. Make them learn something... Why, back in my day I had to come home from school, split fire wood, then study by candle light. 9 planets or 90. If it walks like a duck, quacks like a duck, don't call it a chicken.
We're saying the same thing. You directly, me via subtle sarcasm. However, This is clearly an indirect attempt to influence the science, which I oppose.
If they're going to create such a rule for EPA, then it should also apply to NIH, FDA, DOE, and so on. If they don't make it universal, then they're showing an obvious bias and clearly pushing an agenda which is attempting to influence specific science.

There is no such thing as electromagnetic hypersensitivity syndrome.

They probably did. But, the article claims they are considering whether to release the tortoise or not. Clearly, they're not planning to release it.

No. If the probability is low enough, no resources will be allocated to creating a solution.
And a loud RIP was heard as they created a new tear in the fabric of space-time.
Perhaps the gods were aliens. That's why they seemed god-like in their powers. Yep, it was aliens.
It was aliens, they were here first. Messed with our ancestors. Left a calling sign or two...

It's a failsafe mode for the controller and generator. There are four (4) of them. There is more than enough redundancy.
If it ever happened on a plane, then it means that the maintenance was intentionally skipped. If they reach 248 days of continuous operation then a number of significant maintenance cycles have been skipped (some 23-25 inspection / maintenance cycles that generally require shutting down the electrical system).

Pluto got the shaft. Pluto is round, having reached a hydrostatic equilibrium due to it's own gravity. It orbits the Sun. It's a planet!
