Reactor automatically scrammed on low level due to loss of reactor feedwater pump.The cause of failure was an electric coil in the feed pump governor control circuitry.

After repairs were performed, startup activities were placed on administrative hold while an assessment was performed on recent plant problems.After compl of assessment, the plant was returned to service.
