Licensing risk is a key issue for the industry to move forward with actual plant orders

Previously separate construction and operating licenses were required

– No certainty provided by this process

– Many physical changes were required prior to receipt of operating licenses

– Costs increased due to schedule delays and rework required

Industry has adopted new process which results in combined construction and operating license

New Licensing Process provides New Licensing Process provides regulatory certaintyregulatory certainty

• Licensing decisions finalized before major construction begins• Inspections to verify construction• Limited work may be authorized before license is issued

What makes Nuclear attractive?–Fuel volatility, both gas and coal, is a major concern

–Fuel transport and supplies are showing signs of capacity constraints

–Environmental compliance measures are increasing cost of coal base load resources

–Regulation of carbon dioxide (CO2) emissions is gaining traction

–New licensing process expected to allow cost control

–New design units are smaller and less costly to construct
