## Description

On June 29, 2006, a Notice of Violation associated with a White SDP finding was issued for a finding involving the failure to establish measures to ensure that the Unit 1 electromatic relief valves (ERVs) remained suitable for operation prior to implementing an extended power uprate (EPU) in November 2002. This resulted in multiple ERVs becoming inoperable and unavailable due to being subjected to significantly higher vibration levels during Unit 1 operation at EPU power levels.
