All nuclear plant owners participate in a comprehensive, industrywide materials management program that identifies when components of nuclear plants need to be inspected, repaired and replaced to ensure that the materials from which they are made perform according to standards. By replacing and upgrading major plant components such as vessel heads and steam generators, the industry continues to improve the reliability and performance of its nuclear reactors.

For additional information on the industry’s materials management program and on major plant component repairs and replacements, see Managing Material Condition and Equipment Reliability at U.S. Nuclear Power Plants .
