O vztahu VH a management jsem mluvil v teoreticke rovine. A CEZ jsem pouzil jen jako priklad. VH obecne muze schvalit neco, co neni v souladu se zakony. Management se k tomu musi nejak postavit, protoze on ruci za to, ze je vse v souladu s pravem a pro dobro rizene spolecnosti.
Tim bych toto tema za sebe uzavrel. :-)

Ohledne jaderek. Planovanou zivotnost cca 70 let maji nove jaderky, ne ty stare. Zda jde o pokrok v technologii, nebo marketingovy trik (aby vysla navratnost), nevim. Pokud te to zajima, tak se mohu zeptat veci znalych osob.
Trochu jsem hledal a vypada to, ze je to takto. Starsi elektrarny mely puvodne kratsi planovanou zivotnost. Nyni je v US prelicencovavaji a prodluzuji zivotnost o az 20 let.
"Most of the 100 nuclear plants now generating power in the U.S. were originally licensed for 35 to 40 years of operation; now the NRC is issuing new permits, in 20-year increments, that will allow them to keep running for 60 or even 80 years. Eighty reactors (many plants comprise more than one reactor) have already had their licenses renewed, and many of the remaining ones are likely to come up for renewal in the next decade."

Mozna, ze duvodem proc se v US (a vubec v euroatlantickem regionu) nestavi nove jaderky je to, ze je podstatne lacinejsi udelat rekonstrukci a prodlouzit licenci na stavajici jaderku, nez stavet novou jaderku a tu starou, odstavenou nakladne likvidovat.
Kamen urazu tedy nebude pouze v cene novych jaderek, ale i v tom, ze pro ne v podstate na trhu zatim neni prilis ekonomickeho prostoru....
"While there are significant unknowns around extending the lives of nuclear plants built in the 1970s and 1980s, most people in the industry believe that the reactors can operate safely for 80 years. And it’s economic issues, not technical ones, that are likely to shutter aging nuclear plants over the next 20 years. Cheap natural gas and flattening demand for electricity have combined to make older nuclear plants relatively uneconomical. Although the price of uranium fuel is relatively low, and nuclear plants are comparatively inexpensive to operate (according to the Institute for Energy Research, the levelized cost of electricity from existing nuclear plants is lower, on a per-megawatt-hour basis, than that from combined-cycle natural gas plants), flagging demand, high maintenance costs, and competition from cheap natural gas are all combining to make it less attractive to utilities to keep older nuclear plants running."
