  1. Re:Progress on NRC Approves New Nuclear Reactor Design · · Score: 1

    > *induced* fission

    Engineers commonly use fission to refer to induced fission and decay to refer to spontaneous decay. I was merely commenting because AK Marc is (self-admittedly) using dictionary definitions and not the definitions that engineers use. The goal of my comment to was clarify what engineers mean when the say fission.

    Nuclear Engineering (student) here.

    >The decay was an atom splitting into two smaller atoms and energy, which is fission.

    Fission in the context of engineering refers to the use of neutrons to force atoms to split, not to naturally decaying isotopes.

    >The question was of why would fukishima need active cooling when passive cooling is so "easy" to do.

    Because it wasn't designed to use passive cooling. Passive cooling requires your reactor to be designed to facilitate it (all gen 3+ are designed like thisâ"I believe the NRC refuses to certify anything that is nonpassive). Passive cooling refers to not requiring power to run the coolant pumps or anything. The AP1000 is designed to using convection of steam inside the containment building to cool the reactor.

    If you are limiting the owner's bandwidth it is stealing. The "stealing" analogy only applies to everything beyond to router. Which if the owner pays by the (giga)byte does remove resources he paid for.

  8. Re:Sea water for cooling? on Millions of Jellyfish Invade Nuclear Reactors · · Score: 1

    The Shimane Nuclear Power Plant is a Boiling water reactor. This means it has two water loops in it. One is boiled by the reactor and turns a turbine. A second (probably from the sea in this case) is used to condense that steam and recycle it through the reactor. For any heat based power generation you need a final heat sink, usually the atmosphere (cooling towers) or a body of water for nuclear power plants; coal plants usually have an entirely open system and just go water source to air.

    Most of Japan uses BWRs. https://secure.wikimedia.org/wikipedia/en/wiki/Boiling_Water_Reactor

    As a upcoming freshmen let me make a few points. 3. The Green Giant has always been Shrek, not the big guy picking vegetables. Shrek came out in 2001. I remember part of the first 11 years of my life. Including the Jolly Green Giant (not much but enough to never call Shrek the green giant). 4. They have never used a card catalog to find a book. My first Elementary School had one, so did the public library back then. 8. Tattoos have always been very chic and highly visible. That's pretty regional, it is only in the last few years they have caught on where I live 19. They have never understood the meaning of R.S.V.P. Send a Reply/Confirmation? 21.

There have always been flat screen televisions. Maybe, but how many people had them earlier in the 90's (my childhood). 51. Britney Spears has always been heard on classic rock stations. She didn't really become popular till the late 90s. How'd she get on classics for my entire life when she didn't start until halfway through it? 53. Someone has always been asking: "Was Iraq worth a war?" They're gonna be asking that a long time. 54. Most communities have always had a mega-church. I let this slide because they used "most".
