It
- is couplete s W for retesting of piping an w Mted with the Diesel Generator FLcl Oil and Inbe Oil systems. Additional restraints were installed during the B.C-1 refueling cutage. However, further modifications are found to be mry.- Those nodifications involved the replawmust of rigid piping
-with flexible piping. Vibration testing following empletion of the modification indicated that overall vibration levels had been r d W.
However, vibration levels in isolated portions of the piping still W_
allowable criteria. These levels wre evaluated and found to not constitute an inninent danger of failure. To resolve these isolated problems, modifications are planned which will result in a piping configuration similar
. to Unit 1.
The noilfications include replaw-uit of non-standard fittings wjth standard fittings, deletion of umry flanges, and valve relocation.
-Due to the extent of these modifications, they are schMiled 'for tha Unit 2
