MAR 2 1 1979 NOTE TO FILES:
March 21, 1979 TELECON WITH STONE AND WEBSTER X
I called Mr. Kennedy of Stone and Webster to discuss my March 20, 1979 memo regarding future action to resolve outstanding seismic questions on the five shut-down plants.
The purpose of the call was to clarify the type of reanalyses required for each plant.
Discussed were:
- 1. Sizes of small piping that is designed using chart or other manual methods should be identified. If the methods used for such small piping are different than the methods currently used the differences should be noted and justified.
- 2.
Reanalysis of primary system piping performed by NSSS is not required.
- 3.
All safety related piping (other than Item l and 2) and supports are to be analyzed or reanalyzed as needed using an acceptable code.
