On October 22, 1985, the Nine Mile Point Unit I (NMP1) electric fire pump was removed from service to perform an NRC committed modification.
During the installation, a ground fault was inadvertently induced on station batte y board #11. The fault was determined to be in the diesel fire pump electrical control circuitry so the battery #11 source was removed from service for troubleshooting. This action rendered the diesel fire pump administrative 1y inoperable since one of its redundant power supplies was disconnected. The fault was subsequently cicared and both fire pumps returned to service on October 23, 1985.

In accordance with Technical Specification 3.6.7c, we hereby submit the following Special Report concerning an administrative 1y inoperable fire suppression system.

On October 22, 1985, the Nine Mile Point Unit I (NMP1) electric fire pump was removed from service to perform an NRC committed modification.

During the installation, a ground fault was inadvertently induced on station batte y board #11.

The fault was determined to be in the diesel fire pump electrical control circuitry so the battery #11 source was removed from service for troubleshooting. This action rendered the diesel fire pump administrative 1y inoperable since one of its redundant power supplies was disconnected. The fault was subsequently cicared and both fire pumps returned to service on October 23, 1985.

Although the diesel fire pump was declared administrative 1y inoperable 3

due to the absense of one of its redundant control power sources, the normal source from battery #12 was in service which would have provided automatic starting capability for the fire pump. Additionally, the diesel fire pump was capabic of being started manually at any time without any DC control power by utilizing the starting method detailed in surveillance test N1-ST-SA3,
