Review of fuel failures in water cooled reactors.

This publication responds to the growing awareness of a need for open discussion and concerted actions to improve nuclear fuel reliability. It contains unique worldwide statistics on fuel failure rates, covering about 96% of water cooled reactor fuels. This gives the most representative picture of f...
