RE: Sicurezza impianti e costi

Non prendere in esame la sola sicurezza, conta anche la percezione della sicurezza.

Following the 2011 Fukushima Daiichi nuclear disaster, costs are likely to go up for currently operating and new nuclear power plants, due to increased requirements for on-site spent fuel management and elevated design basis threats.[4]

P.S. dovevo scrivere kwh, non kw/h

en-wiki è piena di forvianti e subdole spiegazioni, la devi prendere con le pinze ,in quanto mescolano il tutto facento un gran pasticcio con la scusa di chiarire che il nucleare ,ora non è conveniente.... dove?
Ancora con questa menata?
Because of the large capital costs for nuclear power, and the relatively long construction period before revenue is returned, servicing the capital costs of a nuclear power plant is the most important factor determining the economic competitiveness of nuclear energy. [ 7 ] The investment can contribute about 70% [ 8 ] to 80% [ 9 ] of the costs of electricity.

Private generating companies now have to accept shorter output contracts and the risks of future lower-cost competition, so they desire a shorter return on investment period — this favours generation plant types with lower capital costs even if associated fuel costs are higher. [ 12 ] A further difficulty is that due to the large sunk costs but unpredictable future income from the liberalised electricity market, private capital is unlikely to be available on favourable terms, which is particularly significant for nuclear as it is capital-intensive. [ 13 ] Industry consensus is that a 5% discount rate is appropriate for plants operating in a regulated utility environment where revenues are guaranteed by captive markets, and 10% discount rate is appropriate for a competitive deregulated or merchant plant environment; [ 14 ] however the independent MIT study (2003) which used a more sophisticated finance model distinguishing equity and debt capital had a higher 11.5% average discount rate. [ 3 ]

Come ti ha già spiegato Neumann, i confronti sono tutti li da guardare,studiare o controllare.

Una fredda nebbia illividisce il cielo,
le notti incominciano prima.
Tutti conoscono il declino,
ma pochi ne discernono la linea di confine.
