The calandria is in a vault, which is generally filled with light water (shield tank). The purpose of the light water is shielding and keeping the temperature of the concrete low. It's not really meant to be a heat sink.
The calandria is filled with heavy water, which *is* meant to be the ultimate heat sink for certain types of accidents (large loss of coolant accidents, for example).
This is exactly the situation in Canada now. Bell is forced to lease out the copper to third party ISPs. However, they get to impose their own throttling/QoS (hurray for laggy connections to a text-based game because I dared to have a torrent running (capped at 25 kB/s) during their 'peak' hours).
In fact, Bell even got a more favourable decision from the CRTC. The gist of it being... They can charge the competition for bandwidth that their customers use beyond what Bell offers their own customers (e.g., If Bell offers 60 GB/month, then they get to extract $x from the third-party ISP for each customer that goes beyond 60 GB/month). It is no longer even competition if you're told that you can't offer something on even slightly different terms.
Any power plant that runs on steam is going to involve pressure vessels. There's so little energy in steam at atmospheric temperatures, that it wouldn't be efficient (or economical) to extract the energy. The Wikipedia article on the BWR seems to say they run at roughly 7.6 MPa (so boiling occurs at ~285 C).
As a recent engineering graduate, I can only confirm that you're far too accurate for my liking. Engineering students think that they have it all figured out, and go on to design some wonderfully impractical items.
Almost all of which could be solved by simply asking someone with experience. The unfortunate reality is that many engineering students are taught that 'labourers' opinions aren't valuable. The simple truth is that they provide the 'applied' to the science that was studied. It's a shame, but many students never learn this, and end up grounding the wrong wire, so to speak.
Most people think 'theme' means desktop background, so that's probably where they'll look first. And what is everyone used to? Right-click on the background, and pick "Change desktop background."
That actually just opens up to inside the 'Appearance Preferences' on the background tab. The Theme tab is the first one in there.
Just to further elaborate... Microsoft was taken to court in Quebec over this exact issue. They lost. Holders of MCSE are not allowed to refer to themselves as engineers in Quebec. They can use the acronym, and only the acronym.
(especially Canada) you can't call yourself an Engineer unless you have an Engineering degree
That's not entirely true. Engineering is a self-regulated profession, much like doctors. You must become certified (in Canada) by the provincial licensing body (Professional Engineers Ontario, for example) before calling yourself an engineer. I'm reasonably sure you don't need an engineering degree (at least not a formal one) to become a P.Eng. You must have the knowledge and be able to demonstrate it. It just so happens that most people with a P.Eng. have also completed an engineering degree.
I read the summary, and I read the article. Both contain only the name 'Davis' for the quotes. Maybe I'm missing something, but who is this person? I kind of doubt Davis is short for Air Force Gen. Kevin P. Chilton, the only other name mentioned in the article.
Except you're talking about a reactor here. Computers can be put in charge pretty easily. In fact, they're quite good at it.
CANDU reactors, in particular, are controlled directly by two computers (one controlling, the other performing the same calculations/operations, just not controlling anything unless there's a problem). I'm sure you can find instances where the reactors have been tripped spuriously, but you'll struggle to find an instance of a reactor being allowed to run wild due to a computer. Operators aren't even credited with any action in CANDUs for the first 30 minutes (or something like that) after an accident.
I really doubt that a snapshot from a satellite of nuclear plant would increase risks. I mean, come on... it's not like their locations are secret to begin with. What would you gain from seeing the satellite image? You could see... a concrete dome. Fascinating. Lots of utilities have pictures of their nuclear plants available online.
Also, not all large power plants are out in the middle of nowhere. Three Mile Island isn't too isolated. Pickering Nuclear Generating Station (Google Maps link) is in a reasonably populated area, just outside of Toronto.
Let's see... maybe because a certain percentage of people in high school are likely to be interested in structural engineering. At a cost of $30, it's really an insignificant amount and many high school students are unlikely to know what structural engineering firms are around.
Or, you could just think of it as a charitable donation on behalf of the firm.
Not to be picky about the summary, but that video wasn't shot at 4000 feet. It was shot at 1.5 miles, which is about 7900 ft. It's the first sentence of the article.
A mile and a half (two and a half kilometers) underwater, a remote control submersible's camera has captured an eerie surprise
I don't remember seeing the real life version of this, but I do remember seeing something similar in a movie.
In Mumford, the IRS agents made sure to get their target. They planted evidence, harassed accountants (because every accountant has something to hide). And, at the end of the day, a small business owner offed himself because the scrutiny got to him.
Good movie, except for the entire 'romantic' portion.
The last remaining benefit of American culture is our tendency to foster creativity in our kids.
I cannot explain it but over the last several years I have yet to see an Indian developer who was trully creative and innovative.
And, in the last several years, I haven't seen any truly creative kids. Just a bunch of fat kids who have an enormous sense of entitlement, and watch TV and play videogames in their environment that fosters creativity so much.
Looks like our anecdotal evidence says different things.
My roomie had the exact opposite experience using Linux.
He likes to play games (only really the ones he can buy from Steam).
About a year ago, his laptop died on him, and the store replaced it for him with a 'new' laptop running Vista. Well, that's all fine and good except his games didn't run smoothly (at all). He ended up installing OpenSUSE 10.3 when it came out.
There's an OpenSUSE repository for updated versions of Wine, so he just downloaded and installed the RPM for a newer version from there.
Result: Games available via Steam are running better than they were in Vista, and his headaches are minimal.
That's just wrong. Let's say you're using a multi-user system (like... a lab computer), and you want to backup some data. You're suggesting that you should require admin privileges to burn it? Also... what if *I'm* the owner of the disc, and not the admin? Shouldn't I be allowed to burn it? Or make it into a coaster?
Please note, K3b (using distro defaults, generally) does not require you to run as root to burn a CD/DVD.
I can only hope I didn't detect the sarcasm in your post.
I can't speak to every point, but a terrorist target?
Have you ever tried to destroy a nice big steel vessel inside of a 3 foot steel reinforced concrete containment building?
From the wikipedia article...
In 1988, Sandia National Laboratories conducted a test of slamming a jet fighter into a large concrete block at 481 miles per hour (775 km/h) [10][11]. The airplane left only a 2.5-inch deep gouge in the concrete. Although the block was not constructed like a containment building missile shield, it was not anchored, etc., the results were considered indicative. A subsequent study by EPRI, the Electric Power Research Institute, concluded that commercial airliners did not pose a danger. [12]
The Turkey Point Nuclear Generating Station was hit directly by Hurricane Andrew in 1992. Turkey Point has two fossil fuel units and two nuclear units. Over $90 million of damage was done, largely to a water tank and to a smokestack of one of the fossil-fueled units on-site, but the containment buildings were undamaged [13][14].
Ah yes, that didn't jump out at me immediately. In all the excitement about no feedback from sellers, I neglected to take note of the buyers having less time to leave feedback.
My bad.
I think it's worth pointing out that the buyer can still leave feedback. It's the seller that can't leave negative feedback.
It helps to eliminate the problem of power sellers not leaving feedback until the buyer leaves feedback. If you leave negative feedback on someone with 10,000 transactions, he's still close to 100% positive (assuming he was close before). If that person retaliates, and leaves negative feedback on someone's third transaction, that hurts them a lot more.

I would put it on the path to Chernobyl. It was willful negligence on the part of the plant owner.

That's how I'd explain it to someone, at least.
