Why has the construction cost gone up?-demands by the public? Will public perception change?- Heat exchanger failures?(Auto radiatiors a few% of cost per KW)- increased real safety?(yet analysis is cheap)-increased regulation? CALState University Sacramento. April 11th 2002

Improved Fuel AvailabilityFuel for 30 yearsNo incentive for explorationMore exploration -> more uraniumImproved “burnup”(1973) 20,000 MW days/ ton(1999) 40,000 MW days/ ton(fewer fuel outages)This brings cost down CALState University Sacramento. April 11th 2002
