On January 29, 2007, a Notice of Violation was issued for a Severity Level III violation. The violation involved the licensee's failure to update its FSAR in 1983 which, combined with the licensee's continued failure to fully understand the facility's licensing and design basis since that time, impacted the licensee's ability in 2005 to understand the current Point Beach licensing and design basis, and resulted in a performance deficiency. The performance deficiency also impacted the NRC's ability to perform its regulatory function. The licensee's failure to update the FSAR and understand the facility's licensing and design basis represented a challenge to the regulatory envelope upon which certain activities were licensed, such as reactor vessel head lift activities.
