Ignalina – Lithuania
CURRENT SITUATION
• 438 plants provide 16% of the world’s electricity (6% of energy)
• Nuclear supplies ~ 35% of the EU (50% off peak)
• Nuclear supplies ~20 % of the US• Worldwide, 93 plants planned for 2016,
37 are under construction, 8 scheduled for operation in 2002
CURRENT SITUATION
• OF THE WORLD’S TOTAL ENERGY SUPPLY, ABOUT 75 PERCENT IS SUPPLIED BY FOSSIL FUELS ( ~ 6% is nuclear )_

Unplanned Automatic ScramsThe unplanned automatic scrams per 7,000 hours critical indicator tracks the median scram (automatic shutdown) rate for
approximately one year (7,000 hours) of operation. Unplanned automatic scrams result in thermal and hydraulic transients that affect plant systems. The scram rate has been significantly reduced since 1980. In 2000, 59 percent of
operating units had zero automatic scrams.

degradation of important safety equipment;a major transient or an unexpected plant response to a transient;degradation of fuel integrity, the primary coolant pressure boundary, or important associated structures;a reactor trip with complications;an unplanned release of radioactivity exceeding the technical specifications or regulations;operation outside the technical specification limits;other events considered significant

Collective Radiation Exposure (PWRs)
The collective radiation exposure indicator monitors the effectiveness of personnel radiation exposure controls for pressurized water reactors and boiling water reactors. Low exposure indicates strong management attention to radiological protection. Worker exposure has been reduced significantly over the past decade. The 2000 values
continue to be better than the 2000 goals.

Volume of Low-Level Solid Radioactive Waste (PWRs)
This indicator monitors the volume of solid radioactive waste processed per unit for pressurized water reactors and boiling water reactors. Minimizing radioactive waste reduces storage, transportation and disposal needs,
lessening the environmental impact of nuclear power. The 2000 values continue to be better than the 2000 goal.

TECHNICAL CHALLENGES
Westinghouse View on Products for Future Markets
• Markets that are still regulated, majority of energy imported, and/or have limited sites (e.g., Asia)– Large advanced LWRs (e.g., APWR, APR1400) are a good fit
– Larger passive plants are also being evaluated
• Markets that are deregulated with pipeline natural gas as principal competition and/or where potential sites are plentiful, but may be limited by thermal aspects or grid infrastructure (e.g., US/UK)– Passive plant technology (e.g., AP600, AP1000)
– Small/modular designs with substantial shop fabrication (e.g., PBMR)

SOCIAL AND POLITICAL CHALLENGES
Positive Media Signals
GOVERNMENT POSITIVE• National Energy Policy - recommends
expansion of nuclear
• Congress supportive - significant funding for DOE and NRC
• Secretary of Energy - programs aimed at new build before 2010, and extensive support for innovative designs by 2030
• Southern Governor’s Association strongly endorses expansion
INDUSTRY POSITIVE
• Multi-utility coalition is exploring a joint venture for building several new plants
• Requests for early site approvals are expected as early as 2003
• Fed. Reserve Board Chairman has said nuclear is “an obvious alternative to coal in electric power generation.”
• Financial community thinks it possible
THE PUBLIC IS POSITIVE
• “Do you strongly favor, somewhat favor, oppose or strongly oppose the use of nuclear energy as one of the ways to provide electricity in the US ?”
• Bisconti and Richards

ISSUES FAVORABLE TO NUCLEAR EXPANSION
• Cost (operation)
• Fuel diversity / energy independence
• No “greenhouse” emissions
CLIMATE SITUATION• “The seriousness of climate change is still
widely misunderstood. Climate influences the productivity of farms, forests, and fisheries, the geography of disease, the livability of cities in summer, damage from storms and floods, property damage from higher sea level, the cost of engineered environments, and even the distribution and abundance of plant and animal species. A few degrees in the average global temperature would entail highly disruptive alterations in climatic patterns.”
CLIMATE CHANGE EVIDENCE
• Average temperature of the earth has risen ~0.8 degrees C in 100 years
• 15 of the 16 hottest years since 1860 have occurred since 1980
• 7 of the hottest years have occurred since 1990
• The last 50 years constituted the warmest half century in 6000 years

ISSUES CHALLENGING NUCLEAR EXPANSION
• Cost (capitol)
• Proliferation concerns
• Waste / transportation
• Security
WASTE / TRANSPORTATION
• President Bush just recommended Yucca Mountain as a repository, but
• National Research Council and Harvard/University of Tokyo study suggests new thinking
• Over 3000 fuel shipments covering 1.6 million miles have been made safely with no release of radioactivity
SECURITY
• “Nuclear power plants are certainly far more capable of resisting an aircraft attack than any other civilian structure…. Nuclear power plants have long had defensive capabilities that far exceed those of other civilian infrastructure”
• Chairman Richard Meserve,
• U.S. Nuclear Regulatory Commission
SO WHAT IS THE BOTTOM
LINE ???
• “THE CHOICES WE MAKE ABOUT ENERGY . . . IN THE YEARS AHEAD WILL AFFECT ECONOMIC WELL-BEING, ENVIRONMENTAL HEALTH, AND INTERNATIONAL SECURITY EVERYWHERE IN THE WORLD FOR MOST OF THE 21st CENTURY.”
• Prof. John Holdren, Harvard University, Kennedy School of Government
SO, WHAT ROLE WILL NUCLEAR POWER PLAY IN THE FUTURE ?
FOR THE U.S., FOR THE WORLD?
It’s difficult to make predictions,
• especially about the future !
