for example, a change to achieve consistency throughout the Technical Specifications. The proposed change will provide consistency with the F-13 interlock. The F-13 interlock is the input from the turbine impulse pressure channels to the P-7 interlock. The proposed change provides consistency with the North Anna Setpoint Study and PLS document. The proposed change will also allow the systems to be operated as designed.
