DESCRIPTION OF EVENT:
I On Oc tober.18,-
- 1964, at apFroximately 1700 CDT, during-performance ofi
'" SEISMIC INSTRUMENTATION FT&C" procedure (HNP-1-3980), personnel found blown
' power supply circuit fuses for Triaxial Time-History,
LAccelerographs for the Diesel Generator building-130' elevation'
-( 2 L 51-N021 ),
Reactor Building.87' elevation
~on drywell-pedestal (2L51-NO20), and drywell feedwater inlet to Reactor Pressure' Vessel-(2L51-N004).
Further investigation revealed that the power. supply circuit to 2L51-N004 instrument loop was short circuited which,-in turn, ; blew the common circuit power supply fuse for all of'the above listed - accelerographs.
The shorted power circuit cable to-the 2L51-N004 instrumentation loop was lifted, and the blown fuse was replaced.
2L51-N020 and 2L51-NO21 were returned to operable status.
During the. next extended drywell entry on. Unit 2, the short circuited power supply cable to the 2L51-N004 instrumentation loop will be investigated to.
determine what-repair is necessary.
restore to
- 2L51-N004 to ooerable status.
The 2L51-N004 instrumentation loop will be repaired and returned to operable status.
