    You think they built the plant 40 years ago and have done literally nothing in terms of maintenance and/or upgrades since that time?
    Do you understand what high ambient radiation does to the crystal structure of construction materials? 40 years is a very very long time in the operational lifespan of any nuclear power plant. Unless they have completely replaced the core hardware itself at least once, as well as the heat management system (which is entirely possible) the reactor could very well be in a seriously weakened state from the intense exposure. Every functional part of a plant is exposed to elevated radiation levels, spreading the material degradation throughout the system.
    Nuclear energy is substantially better for the environment...
    Not really. The enormous amount of energy that goes into fuel acquisition and refinement makes it nearly a wash when compared with other forms of electric energy production. When you add in the disposal of waste, both spent fuel and low level radioactive construction materials, the equation starts to creep into the red. Of course, you might be able to prove me wrong, if you could find me an example of an operational nuclear power plant built and run entirely, or even largely, with private funding.

    i think alot of people care about the environment.. but alot of people dont care about greenpeace. in my eyes greenpeace has become a joke. i dont know mush about them but it does not seem like they do anything helpfull but to yell at the top of there lungs at people that can get them the most amount of publicity.

    the way i see it is. apple is really popular in the public eye. so they become a natural target for anyone that wants their voice heard. well at least thats how i see it.

    the last time i heard somethign from greenpeace was back in the 90's.

    i think you misunderstood the recent reports: the consensus interpretation is that iTV does require a computer, and that the hard drive is just for buffering.

    I'm not seeing any consensus interpretation that suggests anything of the sort. I can also say with some certainty that the hard drive is "not just for buffering". At the kinds of data volumes streaming media generally runs at, you can store a couple of hours of video in a gig of RAM. This is considerably cheaper, lower power, and smaller, than a hard disk drive. Why would you put a hard disk drive in a device solely for "buffering"?

    What I'm seeing, according to the reports so far, is a machine that can make use of local iTunes libraries, but can also show media streamed directly from the iTS.

    It makes no sense for Apple to sell an STB that requires a computer. They can make a much more limited device for that purpose, and such a device would not bring the concept of streamed media "to the masses". We don't have all the information at this point, but there's absolutely nothing about the iTV that suggests it's some pricy bolt-on for an existing multimedia computer installation. There'd have been no point in pre-announcing it if it was, and it'd be a complete disaster if it were.

    These people are fleeing the "yellow light of death� on PS3 or "red ring of death' on 360.

    That's a complete joke, surely? There's no way you can compare console gaming, in basically a home arcade, to swiping your fingers around on a 3.5" screen. No way. I am a gamer, and always will be.

    Gaming on the iPhone is good for 2-minute bursts, such as when sitting on the toilet. It's not a great games device. Most of the games are cheap with no replay value.

Unfortunately, his opinions and those of the people like him are directly resulting in my civil rights being violated. We are cretins because we want things changed?

    Damn right. What are we supposed to say- "Oh, you don't like us and want to deny us rights? Ok, that's just your opinion! Cool!" **** that. Sorry, not gonna happen.

    my guess keep cooling it with water. the reactors are shot and will have to be replaced as the sea water destroyed them.

    I think they are trying to keep them cool and cool them off enough to be able to take the reactors out and replace them. This would allow the planet to keep on be used. Pumping concrete in them forces the reactor buildings to be worthless and stuck their were forever as they can not move the waste to a better location.

    I hear you ... this story unfolding is so sad. That whole area of such a small country could virtually end up being uninhabited ... nobody will want to live anywhere near there.

    There is one error in your calculation: The 2.33 GHz Clovertown and 3.00 GHz Woodcrest cost the same, so you would expect the same price for both systems (price of 2.66GHz Woodcrest + $800, like today). However, the price difference between 2.66GHz Clovertown and 2.33GHz Clovertown is $1172 - $851 = $321 _per chip_ which makes it $642 _per eight core system_.Quite. So + $1400 you think makes it $3899. No problem. Still a bargain - at least for me it is. My cars are all paid for. ;)

    You know what I hate about crap like this?

    People read it, and then point their respective (washed in soap with chemical additives and toxins) fingers at Appple, because it makes them feel good. "Yeah, this Apple stuff is crap!"

    Then they go drive a block down the street to get milk from a cow who's waste runoff pollutes the local river, sit down and watch their TV with power generated from a coal-spewing power plant while eating dinner from plastic packaging that came from oil that was refined at a plant that contaminates the environment.

    Unless you live on an uninhabited island, catch all your own food and generate your own power, you have no room to talk. None of us do.
    Excellent summary.

    While I am not a nuclear engineer, I do have a fair amount of knowledge in the area, so with that in mind I can personally say that this will NOT become another Chernobyl situation. Again though as a disclaimer, this is not my career.

    With that said, the BWR should be fine. What we saw earlier was the steam blowing apart the structure-- this just means that they didn't do their job in relieving the pressure. The core should be intact, and the reports state that the housing is still in place. When the control rods are inserted into the core, the rods will not melt down, however heat WILL still be produced. In this case, steam. Steam voids moderate fewer neutrons, causing the power level inside the reactor to lower. Furthermore, there should be safety overpressure valves... not sure why these didn't work; they may not be there due to the age of the plant.

    To quote wikipedia about BWR safety:
    Because of this effect in BWRs, operating components and safety systems are designed to ensure that no credible scenario can cause a pressure and power increase that exceeds the systems' capability to quickly shutdown the reactor before damage to the fuel or to components containing the reactor coolant can occur. In the limiting case of an ATWS (Anticipated Transient Without Scram) derangement, high neutron power levels (~ 200%) can occur for less than a second, after which actuation of SRVs will cause the pressure to rapidly drop off. Neutronic power will fall to far below nominal power (the range of 30% with the cessation of circulation, and thus, void clearance) even before ARI or SLCS actuation occurs. Thermal power will be barely affected.

    In the event of a contingency that disables all of the safety systems, each reactor is surrounded by a containment building consisting of 1.2–2.4 m (4–8 ft) of steel-reinforced, pre-stressed concrete designed to seal off the reactor from the environment.

    Again; BWR =/= graphite moderated reactor. Why does no one get this?! Everyone will be fine.

    Two more bones of contention (which will give you my perspective):

    -I personally believe the linear no threshold model is crap, even with the adjustment factor

    -I also personally advocate the use of thorium... there's many benefits, melt-down control being one of them (because of MSR)... also although there's still fabrication issues, thorium can be used in existing LWRs. There is also proposed designs where the thorium has to actively be fed into the core, providing a great shutoff mechanism. The only con to this is the fact that thorium is more radioactive than uranium, so it's potentially more dangerous. I think the pros outweigh the cons.

    Do you have a link for this? I'd like to read about it. I would think a system setup to automatically scram when power is lost would be the ideal.

    Sure! It's really rather cool. (No pun intended)

    For starters here (http://en.wikipedia.org/wiki/Boiling_Water_Reactor_Safety_Systems) is the current safety systems that are supposed to be in all BWR, however since this one is from the 80's, it's really hit or miss-- I can't answer that.

    New reactor designs have these systems in place-- for example the Westinghouse AP 1000's. (here (http://www.ap1000.westinghousenuclear.com/ap1000_safety_psrs.html))

    A general link about passive safety here (http://en.wikipedia.org/wiki/Passive_nuclear_safety).

    Basically though, the idea is that human intervention, mechanical or otherwise, is always the weak point in nuclear safety. Instead of relying upon mechanical or man-controlled means, these safety measures employ the laws of physics and thermodynamics, which I hope are always working :D. Many of these systems rely on heat sensitive plugs connected to tanks to flood the chamber or coolant systems via gravity.

    Wow. A bit shortsighted aren't we? (And the Apple pom-pom squad is out in force today).

    Don't you see that all the iOS success does is point out to the Board that OSX isn't where it's at and more resources will keep going to iPads and iPhones?

    If you're a mac user is this really what you want?

    They didn't delete the word "computer" from the Apple name for nothing.

    Why you would be surprised at seeing Apple supporters on a site that is designed for Apple supporters is something for you to discuss with your logic professor. But as for your iOS/Mac argument, I sincerely doubt we will see OS X around ten years from now. I hope we don't. I want Apple to keep innovating, and that means advancement and change over time. So what I hope happens is that the parts of iOS that make sense for OS X get included, and the parts of OS X that make sense for iOS get included, and eventually we'll be talking about something brand new that makes them both look old.

    As a Mac user, that's what I really want. I'd hate to see stagnation.

    Poaching suggests illegal, secret, stealing or other misadventure that is underhanded and sneaky.

    From what I've read so far, and I'd be glad for someone to show me what I've missed, Apple had the job positions already advertised and for all we know these individuals, realizing their companies were sliding, applied to - and were received by - apple which replied with open arms. Does anyone have evidence to the contrary? Would that be poaching? Is this forum, like some others, doing headline greed?

    Your anecdotal evidence, though saddening, proves nothing. Expert estimates place the figure at around 4000 and anything other than that is just playing fantasy conspiracy theory. Playing on people's fears of what is not known is just poor science.

    Perhaps the true figure is an unknown but even if we underestimate the figure by 10 times, it's still small compared to other risks and given that nuclear power is still in it's infancy, that risk can only go down with time as it did in other industries and technologies like cars. I would think the biggest risk from nuclear power at the moment belongs to the uranium ore miners.

    People have the same irrational fear about flying. Every time there is a horrific plane crash, many people become afraid of flying for a short period of time afterwards, ignoring the excellent all-round safety record. Personally, I think it's because with flying or nuclear power, the risk lies outside of one's personal control. Walking or driving appears much safer because you are the one in control, even if statistics prove otherwise.

    I'm not against nuclear power, but the estimates don't always take a lot of long term effects into account and the experts can't even agree. Some think radiation is good for you, and some say the Chernobyl estimate is 140,000 deaths in Ukraine and Belarus alone.
    What's more, the long-term effects of the one instance of a severe radioactive meltdown and leak at a nuclear power plant—at Chernobyl in 1986—has also caused disagreement. The UN's World Health Organization and the International Atomic Energy Agency claim that only 56 people died as a direct result of the radiation released at Chernobyl and that about 4,000 will die from it eventually. But the International Agency for Research on Cancer, another UN agency, predicts 16,000 deaths from Chernobyl; an assessment by the Russian academy of sciences says there have been 60,000 deaths so far in Russia and an estimated 140,000 in Ukraine and Belarus. http://ecocentric.blogs.time.com/2011/03/13/japan-nuclear-emergency-how-much-radiation-is-safe/

    I was following the tweets, the live blogs, and a few crappy cell phone streams during this release.

    Until Apple puts up their official site, it's too early to tell if the new FCP is a game changer.

    Based on the description, it sounds amazing.
    Based on the terrible pictures, it looks questionable.

    I always go into new software releases with an open mind. I'm hoping the new FCP is as amazing as it sounds.

    Whatever it is, $299 is pretty fantastic.

    What about BLU RAY?

    Am I the only one who hopes/thinks that we might see a bluray drive in the new mac pros? I mean, Apple is, afterall, a member of the br camp. And they always seem to want to be the "first" to have a new standard (wifi, dvd burning, firewire)...yes, I know they didn't invent any of these, and they may not have been the absolute first, but you know what I mean

    Last year was supposed to be the "Year of HD", but we really didn't see a whole lot of it other than h.264. I think It would be really impressive if we saw at least a BDROM drive, if not a BDR would be hella coolI hope for it. But only think it might be a long shot BTO option because Blu-Ray recorders are close to $1,000 so far. Even the players are almost $1,000. So this seems like an option for next year.

    I also hope for a dual 5.25" external bay design.

    I did a little reading and now am a one minute expert... :p

    I've read these reactors did auto shut down when the earthquake hit. The problem is that the rods create tremendous persistent heat even after a shutdown, and it is the lack of cooling water that is causing the problem.

    Could it be considered a myth that any nuclear reactor can be expected to automatically safely shutdown when power to all safety systems are lost no matter how it is designed?

    And who was saying this could not be like Chernobyl??

    Chernobyl was 25 years ago and Russia was not very open to outside help ... no matter how bad this escalades ... somehow this will be contained.

    Hi guys,

    I realize that this is a Mac forum, so chances are good that everyone here is happy with their decision to switch from Windows to Mac. But since there's no sub-forum on a Windows forum called "I tried a Mac but didn't like it" I'll ask here. :)

    As someone that has used Windows since before Windows (DOS) and has never used a Mac, what might I NOT like about it?

    What might be uncomfortable or difficult?

    What major learning curves should I expect? Etc., etc...


    I'm sure you get what I'm asking here ;) so please share whatever info you can.

    Thanks in advance!

    Also, remember you asked what you might not like, not what you would like. Other forum members have included some pluses about OS X, but you are headed in the right direction if you went to an Apple store and spent time with a Mac. Keep us posted "JOE" LOL Sorry, I could not resist. :)

    If your still under some illusion of how tech savy they are read through the macrumors forums...... and remeber they are the more tech savy ones!

    I have moved every family member over to mac who has no idea about computer, they are happy. The people I know who work in IT, develop and are really tech savy, still have a PC (and an android, some have both android and iphone)

    Oh yes, being elitist by proclaiming to be tech savvy.

    For starters the correct way to look at it is that Apple users don't HAVE to be tech savvy.

    It all works beautifully the way Apple created it, with almost no learning curve. Unpack your device from the box, hook it up and watch the magic unfold.

    I also don't see that I need a badge of being tech savvy. It's like me driving my car and not caring or needing to know how things work.
    Do I care about compression, valves, spark plug, clutch etc. ?

    I am also sure that there are an equal amount of dumb PC users as there are Apple users.

    Only thing we don't know is if the question:

    "My cup holder doesn't give my cup back"

    (She was talking about a CD drive tray being jammed)

    was from an Apple or PC user first:-)
