High Pressure Coolant Injection and Reactor Core Isolation Cooling Malfunc-tions and Test Programs (Units 1 and 2)

As a result of the simultaneous failure of the High Pressure Coolant Injection syster. (HPCI) and the Reactor Core Isolation Cooling system (RCIC) in June, the licensee completed an extensive test program on Unit 2.

This program was described in detail in IE report 50-321/79-24 and $0-366/79-28. An abbreviated test program was completed on Unit I during this reporting interval which consisted of six automatic starting sequences on the HPCI and RCIC turbines. All starts were successful and measured differential pressures indicated that time delay relays would not be required on this unit. The time delay relays installed on the HPCI system on Unit 2 will be removed as further evaluation by the licensee end NRC has indicated that they are not necessary.

8.

Followup on IE Circulars For the following circulars, the inspector verified that the circular was received., reviewed, and corrective actions taken or planned if appropriate.

IEC 78-18 Dated 11/6/78 UL Fire Test

-

IEC 79-13 Dated 7/13/79 Fire Pump Starting Contactors

9.

Technical Specification Compliance (Units 1 and 2)

During this reporting interval, the inspector verified compliance with selected limiting conditions for operation (LCO's) and results of selected surveillance tests. These verifications were accomplished by direct obser-vation of monitoring instrumentation, valve positions, switch positions, and review of completed logs and records. The licensee's corrpliance with selected LCO action statements were reviewed on selected occurrences as they happened.
