In early August, DC | | Fabricators determined that the instrument had not arrived at Texas Nuclear | | Technology. The device contains 45 millicuries of Fe-55 and 4 millicuries | | of Cd-109. UPS is looking for the device but has been unable to locate it | | to date. | | | | * * * UPDATE 1016 9/27/1999 FROM BRAMBLE TAKEN BY STRANSKY * * * | | | | The package has been located.

The | | B emergency diesel generator (EDG) automatically started due to an | | undervoltage condition on bus E2, and loaded to the bus, restoring power. | | The licensee reported that the operating residual heat removal (RHR) pump | | stopped running due to the loss of power to bus E2, but operators manually | | started the standby pump and restored shutdown cooling within two minutes. | | Reactor coolant system temperature did not increase appreciably during the | | alignment of the standby RHR pump. | | | | The EDG continues to supply power to bus E2 while the licensee makes | | preparations to transfer back to the normal power supply. The NRC resident | | inspector has been informed of this event by the licensee. | +------------------------------------------------------------------------------+
