The affected piping has been replaced.
The licensee plans to submit an update to LER 77-4/lT.
(Closed) Inspector Followup Item (213/77-12-18): The inspector reviewed PORC minutes and interviewed PORC members to verify that revised procedures are reviewed by the PORC, as a group, prior to implementation.
