Exactly what I said - ". . . reprocessing, which we now refer to as 'recycling', is back on the table". I presume by changing the name of the process, some think that the present government can circumvent Carter's Presidential Directive.
But that is incorrect because I have reviewed the MOX utilization in the US and we have reprocessed commercial fuel and we have irradiated MOX in several plants. ================================== For reference: http://www.nci.org/new/pu-repro.htm President Jimmy Carter, Presidential Directive/NSC-8, March 24, 1977 - http://www.nci.org/new/pu-repro/carter77/index.htm President Bill Clinton, Statement on Nuclear Non-Proliferation and Export Control Policy, September 23, 1993 - http://www.nci.org/new/pu-repro/clinton93.htm ================================ Also look for the "Advanced Fuel Cycle Inititiative" - http://afci.lanl.gov/ Basically, Yucca Mountain spent fuel repository has been designed for current and projected discharges from currently operating nuclear plants, presumably with the consideration of life extension from 40 to 60 years for many plants. But if the US builds new plants, either the capacity of Yucca Mountain has to be increased OR a new repository has to be built. AND it is not clear that the US DOE will ever accept fuel at Yucca Mountain! Seriously. That would force the US to reprocess. |

On Fox News yesterday there was a short segment about nuclear plant security and terrorism. It was discussed a bit in here, so I want to ask, in a realistic sense, what is the most damage terrorists could do? Destroy the containment building?

I'd find it hard to believe that they could destroy the containment building. If you had a tank or a howitzer - you'd have to pound away at the building all day to destroy it. Basically, nothing short of a nuclear weapon is going to destroy a containment building in a single blow - and that includes crashing airliners. With all the improvements to the reactor control systems that were instituted in the wake of the Three Mile Island accident to prevent the operators from doing something stupid that could lead to an accident - those same systems which prevent the operator from damaging the plant out of stupidity - will prevent a terrorist from damaging the plant out of malice. Conjectures about what terrorists could do to a nuclear plant are great "scare stories" - which is why "journalists" like them. Dr. Gregory Greenman Physicist |

NuStart Selects Grand Gulf, Bellefonte For Advanced Nuclear Plant Licenses
http://www.entergy-nuclear.com/Nucle...ar&List=Region WASHINGTON - The nation's largest consortium of nuclear power companies today selected Grand Gulf Nuclear Station and Bellefonte Nuclear Plant as the sites it will use on applications for combined construction and operating licenses for new nuclear plants, the first in 30 years. Grand Gulf, owned by an Entergy subsidiary, is near Port Gibson, Miss. Bellefonte, owned by the Tennessee Valley Authority, is near Scottsboro, Ala. |

Nuclear energy will rise from the dead again someday. Think modular fast gas, or pebble bed reactors for now. Middle east oil reserves will be nearly depleted by 2050, IMO. A few countries, like the US, will be able to milk their domestic reserves for a decade or two.

We had to watch a documentary about nuclear energy (and how its dangers are perceived much higher than in reality) and I remember some very interesting facts in the film - though I've forgotten the science behind them (yall will have to help with that).
In one experiment, this guy set outside for a period of time (like 3 hours or so) of a NY or NJ reactor with a geiger counter and measured the radiation. Then, he took that same geiger counter (yeah, it was pre-9/11) on an airplane and found that the amount of radiation exposure a person receives during a one-way airplane trip something like triples the amount of radiation received sitting outside a reactor for the same period (or longer). He then took a geiger counter inside some lady's home and found that the building materials (I think granite and other rocks) that were inside her home were emitting TONS of radiation. Then he followed that lady's husband, who worked at a nuclear plant, from there home into the nuke plant and he set off the detectors (which I guess they have going into and coming out of) going INTO the nuke plant. Ha. Then he went to one of those pill-shaped concrete cylinders of nuclear waste (I forget where) sitting somewhere in the US and sat outside of those for awhile. Again, negligible radiation. Finally, he went to a coal extraction plant (or some type of stripmine) and found that the radiation exposure coming from the surrounding rocks that they had to dig through to get coal (apparently some fairly normal rocks are pretty radioactive, I think) were many multiples the amount of the emitted radiation of a nuke plant. Basically, the film showed how effective nuclear energy can be (they showed how 70% of France is powered by it - and is thus an electricity EXPORTER) and also how overblown and fear-mongering the attacks against it could be. And what was really frustrating was that the groups most vehemently opposed to nuclear energy were the environmental lobbies (the reactionist-type ones) and that, unwittingly, all they had accomplished for their 30-plus years of operation were to increase the market share of coal and petroleum plants - which are the ones that have really been hurting the environment with carbon emissions, etc. Also, my teacher said that the only by-product of a nuke plant (apart from the waste - which he said is only not recycled in US, unlike France et al) was steam. Is that correct? All mistakes in my accounting of this film were mine, please poke around with questions. |

It's really frustrating how candidates who run on a pro-environment platform (at least comparatively) at the same time bash nuclear energy and, whether they want to or not, only increase the fossil fuel-based market share - which they also rant against constantly.
My family is in the oil business and has been for some time (so financially it's no particular sweat to us if the nuke industry tanks) but each one of us sympathizes with the nuclear industry for two reasons. First, every sane person - especially in the exploration business - knows that it's getting harder to find new reserves. In fact, iirc, the ratio of new reserve discoveries-to-oil and gas consumption has been negative (more new demand, less new oil) since something like 1975. The ones we have found are harder to get to -deep sea/artic reserves - and less profitable, making the whole thing enormously more speculative (a risk which gets passed on to the consumer). The market economics of the oil and gas industry are extremely complex and very interesting, but would require an entire thread to fully introduce. But the second reason the oil and gas exploration industry is sympathetic to the plight of the nuclear energy industry is that they are having to face, in a less vicious but more pervasive way, the attacks from folks who seem to always be critical and never constructive (generally, under the 'environmentalist' nom-de-guerre) when it comes to energy supply and demand. For example, there is simply no logic (rooted in understanding of economics or conservation for that matter) in opposing - across the board - drilling in ANWR, middle east oil dependence, AND, at the same time, nuclear energy generation. For whatever reason, there is little compromising on their side, except semantically, with unsubstianted or unreasonable pleas toward things like solar energy, which, right now, simply can't supply (in an economically reasonable manner) the massive mW that nations demand. (And also because the attacks can get pretty personal and vicious. When I tell people my family's in the oil industry, they immediately think and sometimes accuse crazy things like being imperialist propogaters of war in the middle east, drilling in ANWR, destroyer-of-rare algae (yes, that ones real) etc. all the while overlooking the simple fact that, the more the US actually gets cheap oil, the less profitable our industry becomes. Crazy, I tell ya..) I've got shares - which have been tanking, btw - in some nuke energy businesses, simply cause I think they're the real future in energy production. |

Nuclear plants generate low, moderate and high level waste, which are ranked by radioactivity. The high level waste consists of spent fuel, which having operated in the core for 4-6 years, contains fission products. The spent fuel is stored in the spent fuel pool until it cools sufficiently to then put it in dry storage. In theory, the spent fuel is supposed to go to a final repository (once-through fuel cycle plan), which is supposed to be Yucca Mountain, NV. That hasn't happened yet, so the spent fuel continues to accumulate at each reactor/plant site. In the normal course of operation, corrosion products in the cooling system become radioactive. This material (several 10's of kg) is collected on filters, which ultimately must be disposed. This waste is sent to special sites which dispose of low or moderate radioactive waste. Other low-level waste accumulates during normal maintenance. Workers clothing, even with very low levels of radioactivity must be disposed of according to strict rules. |

Yep. Two utilities within the NuStart Consortium. Had 'em for about a year now. Hopefully they'll pick up.
I've only got a limited number of shares currently because 1) it doesn't seem like the nuclear power industry is a particularly nimble creature (with application and building restrictions and all) and 2) I have yet to really understand the innerworkings of nuclear energy consortiums. Mainly I'm banking on the DoE incentives coming to fruition between '08 and 2011. If the next Congress (or President for that matter) does an abrupt about-face - which apparently can happen [thinking of that Cuomo story] - then I guess I'm s.o.l. But like I said, this is more me owning em cause I believe in their practicality (apart from the market). <--- why idealists make bad floor traders...

DOE will be tight on money.
The time to buy ETR was a year ago, but they are doing reasonably. It it prudent to do one's research. |

You are very correct. The rebar in the walls of the containment doesn't get the hefty neutron dose. Embrittlement by neutrons is limited only to those parts of the plant that get a direct exposure to neutrons - namely the reactor vessel and its internals. Dr. Gregory Greenman Physicist |
