Costs associated with the construction
 of new nuclear reactors may pose
 the greatest roadblock to the global expansion
 of nuclear power. Recent experience
 with construction of the newest
 generation of reactors in the West
 has met some difficulties. In Finland,
 Areva, the French nuclear company,
 is building its European Power Reactor
 (EPR) at the Olkilouto facility. The
 project is now 50 percent over budget
 (originally 3 billion Euros) and 2 years
 behind schedule (it was to open in 2009)...
 Costs for new EPR plants are
 now estimated to exceed $6.5 billion.23
 Most of the costs associated with nuclear
 power are capital costs associated
 with plant construction and licensing...
 Experience in the U.S. also shows
 that increased construction times lead to
 greatly increased costs from accumulating
 interest costs.26 And construction
 time has not improved that much. 
 Average construction time globally, in most
 recent experience between 2001–2005,
 was 6.8 years; at best it was five years,
 on average.
