Mislim da su NE neizbežne. Ili NE ili velik uvoz struje i česte havarije i restrikcije.

@ALL

Vidim da vam je glavni razlog briga za nuklearni otpad. VIdim da ste totalno van tokova. Nuklearni otpad se preradjuje, a onaj koji se ne preradi izvozi se (uz nadoknadu). Ima zemalja koje bi za pare prihvatile nuklearni otpad.

A ja cu da vas podsetim da mi imamo Vincu i da ona ima nuklearni materijal.

O boze...
Pa seti se ko je pisao te knjige!
Pa pola Srbije nema ni vodovod!

A imamo i KALNU,gde se ranije skladistio nuklearni otpad,a suska se da ce i sada.

Po meni mnogo bolje rešenje je gasifikacija Srbije.Zbog toga što se kod nas mnogo struje troši na grejanje,pa bi se samim tim smanjila potrošnja struje.Ne treba nam nuklearna energija

Ајде Леги пошто видим да се разумеш,појасни нам како се то нуклеарни отпад обрађује?Колико ја знам Уранијумов низ се исто завршава радииоактивним оловом..

Ne razumem se... Nesto sam cuo, a ono sto nisam, koristim Google.


Evo sta sam nasao:

Transmutation

Transmutation is the transformation of one element into another. The goal of transmutation, in radioactive waste disposal, is to transmute long half-life, highly radioactive elements, into shorter half-life, less-radioactive elements. There are two methods currently proposed for the transmutation of high level radioactive waste: fast nuclear reactors, and hybrid reactors.

Fast consumer reactors are merely variations of fast breeder reactors. These reactors take the plutonium created by nuclear reactors as byproduct, or as fuel for nuclear weapons and "consume" it. This process leaves uranium and other less dangerous radioactive waste. As an added benefit, the isotopes of the elements created as byproducts generally have shorter half lives than the initial plutonium used as fuel.

Hybrid nuclear reactors promise near complete transmutation of almost any high level radioactive waste. The general process is to produce a sub-critical nuclear reactor (i.e. the nuclear reactions would stop under normal conditions) and bombard the reactor fuel with neutrons. The neutrons break apart the large radioactive elements, releasing energy. This energy is used to power the neutron source needed to start the fission reaction. There will be some some high level radioactive waste produced (generally parts of the neutron source) but in comparison to the amount of radiactive waste consumed, this will be minimal. This high level waste will need to be place into long term storage.

Evo, jos malo:

After the fuel has been in the reactor for about 18 months, much of the uranium has already fissioned and a considerable quantity of fission products have built up in the fuel. The reactor is then refueled by replacing about 1/3 of the fuel rods. This generally takes one or two months. {2002 note: Entergy Nuclear, an enthusiastic buyer and operator of American nuclear power plants has been reducing this time for their plants. They refueled their River Bend plant in Louisiana in 17 days and expect to reduce their average refueling outage time to two-three weeks.] Canadian CANDU reactors replace fuel continuously.

When fuel rods are removed from the reactor they contain large quantities of highly radioactive fission products and are generating heat at a high rate. They are then put in a large tank of water about the size of a swimming pool. There they become less radioactive as the more highly radioactive isotopes decay and also generate less and less heat. The longer the spent fuel is stored, the easier it will be to handle, but many reactors have been holding spent fuel so long that their tanks are getting full. They must either send the rods off or build more tanks.

The fuel rods should then be chemically reprocessed. Reprocessing removes any leftover uranium and the plutonium that has been formed. The U.S. shut down its reprocessing plant during the 1970s and hasn't replaced it. European reprocessing plants (Belgium, France, Russia, UK) continue to operate, and the Japanese are building their own - in the meantime sending their spent fuel to Europe for reprocessing. The French plant they use sends their plutonium back to Japan, where the Japanese plan to use it as reactor fuel.

The fission products are then put in a form for long term storage. A large reactor produces about 1.5 tonnes of fission products per year. The fission products are originally in a mixture with other substances, so reprocessing is required to get it down to a 1.5 tonnes. [If the waste is incorporated into a glass, the total weight is 15 tonne. If the density is 3.0 times water, that means the volume of the waste is 0.5 cubic meters, and the volume of the waste glass is about 5 cubic meters. from Prof. Bernard Cohen] Many schemes for long term storage have been devised, but lawsuits and politics have prevented any of them from being implemented in the United States.

The French have decided on a scheme, but I don't know if they have put it into operation. Because the fission products become less radioactive with time, the longer you wait, the easier the task becomes. The Canadians are reviewing a plan for storing waste deep underground in the Pre-Cambrian "Canadian Shield".

The U.S. plan is to store the waste in Nevada in the same area as has been used for underground nuclear tests. This plan is still tied up in long term indecision. A big step forward was taken in 2002 when the President signed a bill to over-rule the objections of the State of Nevada.

Kome to pade na pamet Kalna?
Taj kraj je poznat po karcinomu (ne znam zasto), pa ko hoce otpad u Kalnu neka ide tamo da zivi sa porodicom. Najlakse je drugima uvaliti ...

Imam jednu možda neostvarivu ideju.
Naime, u Brazilu dosta koriste za alkohol od šećerne trske za pogon automobila.
Možda je moguće genetskim inženjeringom stvoriti biljku koja će imati visoko kalorične plodove koji će moći da odaju dosta toplote sagorevanjem ili će moći da se pravi alkohol koji ne ispušta štetne gasove pri sagorevanju.

Opet ponavljam, jedno su price za javnost, a drugo je realno stanje. Sto se tice radioaktivnosti, to jos nauka ne poznaje dovoljno, a posledice su svima poznate. Skoro sam procitao da se u Japanu jos osecaju posledice od atomskih bombi koje su bacene za vreme drugog svetskog rata. Niko ne moze reci koliko ce te posledice jos trajati, mozda jos godinu, a mozda jos milijardu godina, ko zna.
Odpad iz NE je jako veliki problem, pogotovo njegovo odlaganje. Mozda zvanicnici to negiraju, ali verujte mi da je tako. Da bar nema drugih izvora energije pa da razumem i zbog toga sam veliki protivnik NE.
