License Renewal / Second License Renewal
As a safe, efficient, and clean source of electricity, nuclear energy continues to play an important role in meeting our world's growing need for electricity. After a U.S. nuclear reactor has been in operation for 40 years, operating licenses may be renewed for additional 20 years periods. More than 75 plants in the US have already renewed their licenses to 60 years of operation and some owners are now interested in operating their plants for an additional 20 years (an 80-year service life) - termed second License Renewal or SLR. Structural Integrity Associates, Inc. can help ensure your plant will meet the demands of a longer operating life, and make your journey to license renewal and SLR a smooth one.
Our support for license renewal is a natural extension of that initial focus and one we have been providing since the first plants sought approval for operation to 60 years. our fundamental understanding of degradation mechanisms and experience in managing these mechanisms has led many nuclear utilities to turn to us for help in extending the life of their plants.
We have been a key consultant to nearly every U.S. utility that has sought to extend nuclear plant operating licenses to date and remains actively involved with industry efforts coordinated through both EPRI and NEI. The range of our License Renewal and SLR services has grown significantly over time and now can address nearly every aspect of a License Renewal / Second License Renewal project. Having grown alongside the nuclear energy industry, Structural Integrity is a powerful partner through every step of the license renewal process.
