Nuclear Power Plant Basics

What are the advantages of nuclear power? Nuclear Energy Institute Economic Cost What was the promise of nuclear power? How did that work out? Environmental costs of alternatives Did we care about global warming in 1975? Coal Wind farms Strategic issues Why has France pushed for 100% nuclear power?

Reactor Design - Traditional

Reactor Safety What are the design issues? Reactors are steam engines Do they fail safe or do they melt down? How do you protect the environment? Containment Self-moderating - heavy water Pellet bed reactors

Pebble Bed Reactor: A Proposed Fail-safe Design

The Problem of Nuclear Waste Why not just take nuclear waste to the land fill or burn it up? How long does it last? Where do we dispose of nuclear power plant waste in the US? What has stopped the development of a central depository at Yucca Mountain? Where is the waste kept now? Is preventing the disposal of waste a smart strategy for stopping nuclear power?

Chernobyl A graphite reactor without a containment vessel. The reactor itself burned when it melted and created a huge cloud of radioactive particles.

Who Pays if there is an Accident? Price-Anderson Act Allows claims, but limits liability of the industry 1st $300m - private insurance $300M-$10B - risk pool Over $10B - federal government What would the costs of a big accident include? How is this like Katrina? Who really pays if there is a huge accident?
