SUBJECT:
REVERSED SENSING LINES CONNECTIONS Enclosed is our Technical Review on Reversed Sensing Lines Connections.
^
In LER 50-353/90-002, philadelphia Electric Company documented reversed connections of sensing lines to a containment hydrogen / oxygen analyzer.
The root cause of this event was mislebeling of inlet / outlet ports, resulting in the reversed connections.
Our search on NUDOCS and SCSS database revealed 19 additional events relating to this issue. All of these events were caused by inadequate design documents, deficient procedures, and insufficient verification methods. Considering the relatively small frequency of these occurrences and the limited safety significance, no further AE0D action is recomended.
