I nema sustava kod kojeg nema učenja na greškama.

Černobil je nastao u takvoj situaciji. Kontrola <> pokus.

Da, ali školovanje na NE problematici po svakoj novoj lekciji košta previše. Ako padne vjetroturbina sigurno je lekcija jeftinija.

Teško. Nema tehnički zamjenskog rješenja, dapače, i dalje su daleko i najsigurnije i najčišće.

Zamjensko rješenje postoji, ali ne po toj cijeni el energije. Zato se i vraćam na onu

Udar na moj džep zbog veće cijene struje mi se čini manji od onog udara u Černobilu

Nemojte me krivo shvatiti, nemoguće je sad pogasiti sve NE danas, ali je moguće pogasiti ih kroz recimo 20 godina postepeno i zamijeniti alternativom ali umjesto toga grade se nove.

Takav meteor da padne, pogodio Krško ili ne, svejedno.

Ako bi pao meteor koji je počistio dinosaure onda da, svejedno je, ali ako bi pao neki manji a njih naravno i ima više...

Asteroids with diameters of 5 to 10 m (16 to 33 ft) enter the Earth's atmosphere approximately once per year

Small objects frequently collide with the Earth. There is an inverse relationship between the size of the object and the frequency that such objects hit the earth. Asteroids with a 1 km (0.62 mi) diameter strike the Earth every 500,000 years on average.[2] Large collisions – with 5 km (3 mi) objects – happen approximately once every ten million years. The last known impact of an object of 10 km (6 mi) or more in diameter was at the Cretaceous–Tertiary extinction event 65 million years ago.
Asteroids with diameters of 5 to 10 m (16 to 33 ft) enter the Earth's atmosphere approximately once per year, with as much energy as Little Boy, the atomic bomb dropped on Hiroshima, approximately 15 kilotonnes of TNT. These ordinarily explode in the upper atmosphere, and most or all of the solids are vaporized.[3] Objects with diameters over 50 m (164 ft) strike the Earth approximately once every thousand years, producing explosions comparable to the one known to have detonated above Tunguska in 1908.[4] At least one known asteroid with a diameter of over 1 km (0.62 mi), (29075) 1950 DA, has a possibility of colliding with Earth on March 16, 2880, but the Torino scale only works for impact possibilities within 100 years, and thus cannot apply to this asteroid.
Objects with diameters smaller than 10 m (33 ft) are called meteoroids (or meteorites if they strike the ground). An estimated 500 meteorites reach the surface each year, but only 5 or 6 of these are typically recovered and made known to scientists.
