The Nuclear Promise Delivered Through I&C Reverse Engineering and Repair

As part of our mission to deliver the nuclear promise, ATC Nuclear is solving your most difficult I&C nuclear parts aging and obsolescence issues—including analog replacements—and potentially saving you millions of dollars in the process.

Our focus on the nuclear promise stems from our enduring commitment to provide customized solutions to the nuclear industry. Currently, the U.S. nuclear power plant fleet is facing incredible challenges related to obsolete and degraded I&C parts and equipment, potentially hampering continued plant operations. As the need to replace circuit boards and other I&C systems increases, the industry is experiencing lost power generation and reliability due to high costs, qualification and regulatory issues, and cybersecurity concerns.
