REACTOR COOLANT PRESSURE BOUNDARY LEAKAGE FROM CONTROL ROD DRIVE MECHANISM (CRDM) # 21

The licensee reported the discovery of primary coolant system pressure boundary leakage from the CRDM # 21 lower pressure housing. Visible leakage was observed from an area containing a weld. Primary coolant system leakage is stable at approximately 0.3 gpm. The reactor was shut down earlier to investigate the elevated leak rate noted several days ago. Close inspection of the reactor head area noted the above leakage. The primary coolant system will be placed in mode 5 (cold shutdown) for evaluation and repairs. Leakage from this area is unexpected, and the mechanism for failure is not understood at this time.

The NRC Resident Inspector was notified of this event by the licensee.
