Special Report Vibration and Loose Parts Monitoring System )
On November 03, 1994 Channel 3 (Upper Reactor Vessel A) was declared :
l inoperable. The channel sensor failed the acceptance criteria during the performance of PT/0/A/4600/03 (Loose Parts Monitor Spectrum Comparison). )
Problem Investigation Process (PIP) 2-C94-1546 was initiated for tracking; repair i will be completed under work order 94045448. This work order is planned for the end of 2EOC7 outage since containment entry will be required.
Since this channel has been inoperable for 30 days; it is reportable pursuant to Technical Specification 3.3.3.9. j Very truly yours, l l
