This SLC was developed to address the NRC concerns about actions to be taken in the event instrumentation/alarms were out of service which would impair the ability of operators to recognize loss of the non-safety discharge. This SLC shall ensure the proper actions are taken based on plant equipment conditions.

BASES The turbine driven AFW pump steam supply piping is equipped with heat trace to minimize condensate generation during turbine startup operations.

The heat trace control system is designed to maintain the piping temperature within a narrow operating band. The heat trace is energized and deenergized to maintain the piping temperature within the band.

Catawba Units 1 and 2 16.7-13-3 Revision 3

AFW Pump Turbine Steam Supply Piping Temperature Monitoring System

16. 7-13 BASES (continued)

The primary means of monitoring turbine driven AFW pump steam supply piping temperature is the OAC. The OAC data is obtained via piping thermocouples and a local chart recorder (EHCR002). Backup control room temperature monitoring capability is provided via a control room annunciator.

The annunciator is fed via a reflash panel, from the same local chart recorder as the OAC. Alternate means of monitoring turbine driven AFW pump steam supply piping temperature include: the chart recorder local temperature display, the heat trace controller local temperature display, or calibrated, hand-held temperature measuring instruments. It is only when all steam supply piping temperature monitoring capability (including any alternate means) is lost that Condition C is required to be entered. This indicates a condition where the actual temperature of the piping is unknown.

Failure of the heat trace to deenergize could result in the design temperature for the steam supply piping being exceeded. The AFW Pump Turbine Steam Supply Piping Temperature Monitoring System ensures the OPERABILITY of the turbine driven AFW pump by providing control room indication of high steam supply piping temperatures. The OAC high temperature alarm setpoint is established to ensure that the design temperature of the steam supply piping of 600°F is not exceeded. Upon receipt of the OAC alarm due to high temperature on the steam supply piping, personnel are required to open the heat trace supply breaker for the appropriate high temperature section of piping within 15 minutes. The time limit prevents the possibility of the actual piping temperature reaching the piping design temperature of 600°F.

Low steam supply piping temperatures result in increased condensate formation during turbine driven AFW pump startup. A large volume of condensate in the steam supply piping could result in turbine damage, water hammer, or turbine overspeed trips. The AFW Pump Turbine Steam Supply Piping Temperature Monitoring System further ensures the OPERABILITY of the turbine driven AFW pump by providing control room indication of low steam supply piping temperatures. The OAC low average temperature alarm setpoints are set such that a low average system temperature condition is identified prior to the piping system reaching the minimum average temperature required for turbine driven AFW pump OPERABILITY (375°F). The OAC low temperature alarm setpoints for individual piping sections are set such that a low temperature condition is identified prior to the piping reaching the minimum temperature required for turbine driven AFW pump OPERABILITY (225°F). The 225°F limit is provided to prevent the accumulation of condensate in the piping during periods of standby readiness.
