MPMP Power Supply 1 Nuclear Power Update for The Society of American Military Engineers September 15, 2010

MPMP Power Supply 2 Nuclear Power Facilities- Safety is Key 45 inch steel-reinforced concrete 1/4 inch steel liner 36 inch concrete shielding 8 inch steel reactor vessel nuclear fuel assemblies Multiple Layers of Safety

MPMP Power Supply 3 Industry Activities Industry Activities l Licensing risk is a key issue for the industry to move forward with actual plant orders l 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 l Industry has adopted new process which results in combined construction and operating license

MPMP Power Supply 4 New Licensing Process provides regulatory certainty Licensing decisions finalized before major construction begins Inspections to verify construction Limited work may be authorized before license is issued Pre-Construction Construction Verification Early Site Permit Standard Design Certification Combined License Review, Hearing, and Decision Verification of Regulations with ITAAC Reactor Operation Decision Optional Pre-Application Review New page 23

MPMP Power Supply 5 Industry Activities Industry Activities l Industry has adopted several standard designs l Westinghouse AP 1000 (design certified 1/2006) l General Electric ESBWR l General Electric ABWR (design certified 5/1997) l Areva US EPR l Mitsubishi US APWR

MPMP Power Supply 6 New Technology - Advanced Reactor Characteristics lSafety –Use of passive safety systems –Gravity flow and natural circulation designs for cooling lDesign –Reduced number of components and bulk commodities –Eliminate pumps and valves previously needed –Use digital controls and fiber optic cables lProcurement –Standardization of components based on NRC approved design

MPMP Power Supply 7 Fewer Components Reduce Plant Costs Confidential and Proprietary 70% Less Cable 45% Less Seismic Building Volume 80% Less Pipe 35% Fewer Pumps 50% Fewer Valves

MPMP Power Supply 8 New Technology - Advanced Reactor Characteristics lConstruction –Extensive use of modular construction improves quality and reduces on- site construction requirements –Digital controls reduce size and complexity of systems –Shorter construction schedule lOperation and Maintenance – Use of proven systems and components – Man-machine interface advancements – Fewer systems to maintain and test reduces staff

MPMP Power Supply 9 Smaller and Simpler than Current Plants 74147A Sizewell BAP1000

MPMP Power Supply 10 l 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 (CO 2 ) emissions is gaining traction – New licensing process expected to allow cost control – New design units are smaller and less costly to construct Economics
