MEMORANDUM FOR:#J. Murphy, Probabilistic Analusis Staff RES FRON:
J. Angelo, Task Manager, Task A-17, Systems Interaction in Nuclear Power Plants A
SUBJECT:
EVALUATION OF FAULT TREES FOR TASK A-17 Enclosed are fault trees for the reactor coolant pressure boundary safety function which is one of the three safety functions that will be studied in Task A-17.
The other two functions that will be studied are decay heat removal and reactor subcriticality. Also enclosed is a letter from Sandia Laboratories which explains the operational conditions and occurrences that i
are covered by these fault trees.
5.3 series will be submitted to us by Sandia soon.Two additional fault trees in the Figu j
We request that you review these fault trees and give us advice or guidance I
on revising the logic of the trees as necessary. We plan to visit Sandia i
n=-
Laboratories on August 8-9, 1979 to discuss these particular fault trees, I
so we would appreciate receiving your comments before our departure on August 7, if possible.
You are, of course, invited to participate in the l
meeting at Sandia Laboratories.
