Therefore, your response to the violation should include an enhanced schedule for your long term corrective actions for hardware changes which would eliminate the need for immediate operator actions to preclude damage to the EFW pumps during certain design basis transient The violations in Section II in the enclosed Notice involved a failure to provide adequate procedures which resulted in inadequate control of motor-operated valve torque switch and limit switch settings and a failure to provide control over implementation of design changes for the Keowee station battery racks. Because these violations involve issues of lesser safety significance, they have been categorized as Severity Level IV violation In addition to the need for corrective action regarding the specific matters identified in the enclosed Notice, we are concerned about the implementation of your management control system that permitted this situation to develo Consequently, your response should describe those particular actions taken or planned to improve the effectiveness of your program. The violation for inade-quate designs and implementation of design also caused the design bases of the equipment not to be translated into adequate operational procedures.
