I think that was 30 cubic inch hole in the reactor head.
But I think this is probably overblown. Monitoring systems are just that -- to tell people what is going on. Control systems actually do the work and control reactor power, shutdown cooling etc.
We (Unidentified canadian plant) have windows based safety system monitoring software. If it dies, the operators have to watch a bunch of panel meters. Makes their job harder, but I wouldn't consider it "less safe".
I was involved in several "Field Days" where a bunch of Hams had 24 hours to set up their equipment running on temporary power in a temporary location on temporary power, then 24 hours to make as many contacts as possible.
We had an EMO (Emergency Measures Organization) official visit our site and was amazed at what we could do. He figured that an "official" local exercise of that level would cost him half a million $$ and wouldn't be as well organized.
My intererest in Ham radio has declined -- I was more in it for the communication rather than the technical, something internet excels at -- I think they serve a purpose far greater than a hobby.
US nuke plants are just starting to use "digital" control, although they have used computers for monitoring for years. Pretty hard to cause many problems there.
In Canada we've designed our plants to used centralized control computers, with separate minicomputers for ShutDown systems.
Anyone care to hack a non-networked Varian '73 computer? How about a Data-General mini-computer with all software in PROM?
You could kill every windows computer in the plant and cause little more than an inconvenience.
I highly expect the US plants are similarly well secured.
And I haven't gotten into my thoughts on the actual weak points of the system. At best, I think you could disrupt service significantly, but it would be very difficult to cause real damage.
Considering the PR damage it would cause, I'd say that nuke plants take lots of precautions in physical and electronic security. Terrorists go for the most bang for the buck. Nuke plants aren't it.
Testoterone poisoning is responsible for quite a few male "accidental" deaths. That includes such things as car crashes, stupid stunts, golfing in thunderstorms and associated darwin-award winning behaviour.
Have you ever noticed that most "darwin award" winners are male?
There is a basic flaw in the idea of slowing down the spacecraft before reentry:
Orbital mechanics show that there is a direct link between speed and orbit height. If you slow down, your orbit height increases. If you speed up, height decreases. This makes rendevous in space tricky to say the least. The first attempts during gemini were not real successful, but they have it down to an art form now.
So in orbit you have to speed up to get down to the atmosphere. Once you get the atmospheric drag, orbital laws transfer to aerodynamic laws.
We expect our cars to "just work" but at the same time one has to have some understanding of the need to change the oil, and that the squeak coming from the brakes means that it is time to replace the pads.
There is a lot of maintenance work that requires driver attention and knowledge.
It is much the same with a computer. You may not have to know the internals of fixing it, but you should know enough to recognize that it needs servicing, and know who to take it to when those symptoms appear.
The Mars rover that was so successfull used an 8080 Processor -- the same one used in the Tandy Model 100 laptop computer.
Having done low level programming on it, I understand that simplicity = reliability. It comes down to more the design requirements and verification to ensure that everything works together.
Not quite true. Oil sold to the Irving Refinery in Saint John, NB is purchased at an inflated cost from Irving Oil Bermuda, which in turn purchases it at market cost.
The refinery makes no profit, and Canadian taxes are appropriate as such.
Irving Oil Bermuda (consisting of one desk, one phone, and one semi-retired individual) makes a mint and does not pay any tax, per Bermuda Laws.
Why should I shell out $150 (CDN) for an additional hard drive to create a duplicate of what is already in the computer?
If I have a mini-dv camera already, I can back up my drive for $10. I just saved $140 bucks and can store the backup somewhere outside my computer, safe for such things as fire, flood, or theft.
Hacking at its best, taking what you have and making it more useful.
I'm amazed how they do this! I'm only read them in English, but always wondered how they could possibly have translated them -- they were too good! Dogmatix, Cocafonix, Fulliautomatix, are remarkable in that they translate in two ways.
Some like Vitalstatistix or Getafix couldn't be properly translated, so they came up with new appropriate ones.
You have obviously never used a digital camera in the middle of africa. Thousands of photos begging to be taken, and no internet connectivity of any sort (short of sattelite) for hundreds of kilometers.
There is a place for this sort of thing. My Mavica and a stack of floppy disks didn't do too badly, but I really would have liked to have higher resolution.
Ours had many categories apart from speed. I won a couple prizes for "fanciest" for cars that didn't run that fast.
My father made a truly geek car. He took a matchbox mercedes ambulance and made a beautiful model of it. Of course he added a couple flashing LEDs and a siren in it.... He built it 25 years ago, but I found it at their house last weekend -- half way around the world from where he built it!
Our entire school was eligible to enter, and there was a category for "over 15" where custom axle systems were allowed. Those cars flew! The traditional "fast" axle system was to install plates along both sides of the car. A pair of wheels was on a common axle with points on the outer ends. These ends fit into concave bolt ends threaded through the plates.
So to sum up: Speed is all in the wheels and axles. A block of wood with good wheels will beat anything.
You can't install new halon systems, but existing ones are still legal (in Canada, anyway).
However, I wouldn't want to have to fill out all the paperwork involved with a discharge! We had an accidental discharge (a leak, I believe) and they decided it was enough impetus to remove the system.
I think they are using CO2 now. The advantage of Halon is that you can breathe quite comfortably in an atmosphere that will not sustain fire. CO2 works just about as effectively but will not sustain life.
OTOH, more recent studies have shown that just because you can still breath in a Halon infiltrated environment doesn't mean that there are no health effects!
I expect there are more CO2 systems going in now, with lots of alarms to make sure people get out before the atmosphere gets unlivable.
I've seen bigger ones. At the kid's room in Schipol airport (Amsterdam) they had a shed-load of large bricks. In the few hours that we were there, my kids built themselves a fort.
Of course, my pics of it never made it onto my server....
using SA-Exim (and Exim) I can reject messages at SMTP time which are above a set threshold.
Nice to know that not only can I avoid looking at the spam, I can flat out refuse to accept it when it comes in! Mind you, it does save it to let me look at it before I/dev/null it, but gives me much more satisfaction than just dropping it in a different folder.
Bay of Fundy, Anapolis Royal Nova Scotia

Tidal Power a Reality
·
· Score: 4, Informative
There has been a 20 MW tidal station running at Anapolis Royal in Nova Scotia, Canada since 1984. This isn't a first.
There is a perfect location, potentially generating 5000 MW (Sorry for the pdf) on the Minas Basin of the Bay of Fundy between Cape Split and Parsbarro. These are the highest tides in the world, up to 16 metres.The entrance to the basin is approximately 8km wide, and could be dammed relatively easily.
On flows "The currents exceed 8 knots (4m/s), and the flow in the deep, 5 km-wide channel on the north side of Cape Split equals the combined flow of all the streams and rivers of Earth (about 4 cubic kilometres per hour)."
Back to where I started, Environmental impact: There would be huge disruptions to the intertidal zone, where much of the life of the bay lives. Siltation would be a major problem. The Petticodiac river in Moncton, NB, was partly dammed by a causeway in the early 1960's. Since then, the river downstream from the causeway has filled in with mud as it no longer gets flushed twice a day, and no longer gets the full effect of the spring runoff. Many of the rivers running into the Bay of Fundy are muddy. Will that settle into the basin? There are no longer any Salmon going up the Petticodiac river, largely due to the causeway. What effect would a huge dam/causeway have?
Any power generation will have environmental effects. It comes down to a choice as to which effects we choose to live with.

I know they lost a few penguins in the early years to bears, and that was pretty unique.
It doesn't sound too hard, but the difficult part would be removing the "used" beer after it had been processed......
Because it gets filmed in a theater and released worldwide on videotape within a few days of it being in theaters.
By the time a DVD is released, it becomes a non-issue.
We expect our cars to "just work" but at the same time one has to have some understanding of the need to change the oil, and that the squeak coming from the brakes means that it is time to replace the pads.

It is much the same with a computer. You may not have to know the internals of fixing it, but you should know enough to recognize that it needs servicing, and know who to take it to when those symptoms appear.
Then you would could work on it for days without getting it to compile at all.

Gotta love what private companies can do!
That wouldn't take long to saturate the processor. If it were flat html with images, it would just max out the network.
I hope the heatsinks work!
