POSITIVE INDICATION OF COLIFORM IN WATER SAMPLING
Water sampling taken from the office cleaning facility indicated positive on total coliform bacteria. Fecal coliform results were negative. Chlorine residuals established at the time of the sample have been reverified and the licensee believes it was in the sample analysis. Back-up sampling will be taken tomorrow, 11/8/02, and send for sampling verification.
The Licensee notified the Maryland Department of the Environment and the NRC Resident Inspector.

AUTOMATIC REACTOR TRIP ON OVER TEMPERATURE DELTA-TEMPERATURE
"Unit 1 automatically tripped on over-temperature delta-temperature reactor trip signal at 1247. All control rods fully inserted. The 1A auxiliary feedwater pump was manually started to supply the steam generator, and the 1B auxiliary feedwater pump started automatically on Low-2 Steam generator level [18%]. The cause of the transient was apparently a turbine malfunction. Pressurizer power operated relief valves opened automatically to lower reactor coolant pressure, and were successfully reclosed. Steam generator relief valves also opened to lower steam pressure, and reclosed. The plant has been stabilized at normal zero power temperature and pressure per emergency procedures."
The Licensee has notified the NRC Resident Inspector.

AUTOMATIC REACTOR TRIP DUE TO TURBINE TRIP
"Reactor trip believed to be the result of 500KV switchyard maintenance. One Main generator output breaker was open for maintenance prior to the trip, and when the second output breaker opened, the main turbine tripped causing the plant to trip. Emergency Operating Procedure 2, Vital Systems Status Verification has been completed satisfactorily. Emergency Operating Procedure 10, Post Trip Stabilization, has also been completed satisfactorily. The root cause of the trip is unknown at this time."
All control rods fully inserted. Steam generator reliefs lifted to relieve steam pressure, and reclosed. No pressure operated relief valve lifted.
Licensee notified NRC resident inspector.
