Ne JAN 1 1 1973 Docket No. 50-269 Note to Files TELECON WITH DUKE POWER COMPANY AND BABCOCK AND WILCOX - RESULTS OF VIBRATION TESTING ON VESSEL INTERNALS - JANUARY 10, 1973 A conference call with the folicwing participants was held on the above subject.
AEC DUKE B&W Schwencer PWR-4 Parker Kulynych Peltier PWR-4 Barton Steinke Hou MEB Canady Karrasch Fortune o
Harris Others The purpose of the call was to inform AEC of results of the vibration testing of Oconee Unit 1 internals.
1 Primary system (without core) flow was 108 /2% of Nominal Design 1
With core flow will be about 103 /2% of Nominal Design Previous test (without cere) flow was about 111% of Nominal Design The following stress levels are peak to peak divided by 2 values taken with 4 pumps operating at 5320F. For other pump combinations, some stresses were about 15% higher but within the errorband.
