  1. Fukushima I nuclear accident, March 11, 2011 What happened, why and a better design

  2. Fukushima I Nuclear Power Plant • Boiling Water reactor • Second most common reactor type

  3. Boiling Water Reactor

  4. What Happened and Why • Earthquake, magnitude 8.9-9 • Tsunami, flooded the plant • No power to the plant

  5. Radioactive Contamination Measured as far away as 20 kilometres. Varying levels inside and around plant.

  6. A New Reactor Design, Pebble Bed Reactors. • Fuel contained in tennis ball sized pebbles • Passive safety
