Leveraging our global experience and innovative methodologies, Framatome is at the forefront of industry initiatives to utilize risk-informed decision making to manage nuclear assets. As such, we have developed a Reactor Internals Asset Management approach that allows you to cost-effectively meet the challenges posed by the emergent baffle-to-former bolt (BFB) degradation issue.

As the world leader in nuclear innovation, we are the only vendor with a proven risk-based solution for robust asset management. Our analytical method incorporates deterministic models, a statistical model for bolt failure, award-winning inspection capabilities, and extensive replacement experience into a probabilistic framework. Using this road map, you can intelligently and pro-actively plan examination intervals, replacement bolt patterns, and outage duration to effectively control cost through end of life (EOL).
