Review of Licensee Event Reports (92700)
The following LERs were reviewed for potential generic impact, to detect trends, and to determine whether corrective actions appeared appropriate.
Events that were reported immediately were reviewed as they occurred to determine if the TS were satisfied.
LERs were reviewed in accordance with the current NRC Enforcement Policy.
a ~
(Open)
LER 91-09:
This LER reported an unplanned actuation of the auxiliary feedwater system due to personnel error while troubleshooting a
steam generator level instrument.
The licensee plans to review this event with maintenance personnel and developed additional procedure, guidance to enhance troubleshooting activities.
The LER will remain open pending completion of this action.
b.
(Closed)
LER 91-10:
This LER reported a reactor trip which occurred during surveillance testing on an RCS flow transmitter.
This event was discussed previously in NRC Inspection Reports 50-400/91-13 and 50-400/91-15 and was the subject of violations 400/91-15-01 and 400/91-15-02.
