SUMMARY
OF MEETING HELD 1<1TH PPIIIL AT BETHESDA, MARYLAND, ON APRIL 18, 1984 REGARDING PROPOSED MAIN STEAL LINE - HIGH RADIATION SETPOINT TECHNICAL SPECIFICATION CHANGE REQUEST On April 18, 1984, representatives of Pennsylvania Power 5 Light Company met with the NRC staff to discuss the proposed change to the Main Steam Line-High Radiation setpoint of the Susquehanna Unit 1 Technical Specifications.
A list of attendees is provided in Attachment 1.
The current Main Steam Line - High Radiation setpoint is i3 times normal background.
PPSL proposed an amendment to the Susquehanna Unit 1 Operating License to raise this setpoint to <7 times normal background to avoid main steam isolation valve closures and resultant reactor trips when placing condensate demineralizers into service at power.
The slides presented by PP8L to the NRC are provided in Attachment 2.
Based on the information presented, the NRC staff will further evaluate the proposed change.
