| The licensee was going to bring the main turbine on line which was rolling   |
| at 1800 rpm. Two steam dump bypass valves were open dumping steam to the     |
| main condenser to help maintain reactor power at 18%. Unexpectedly two       |
| additional steam dump bypass valves opened.  When these two additional steam |
| dump bypass valves opened the first two open valves initial started to close |
| then they went full open.  Steam generator pressure decreased to the low     |
| steam generator pressure setpoint of 741 psia at which point an automatic    |
| reactor trip plus a main steam isolation signal (MSIS) was generated, main   |
| steam isolation valves (MSIV's) closed.   All rods fully inserted into the   |
| core.   Atmospheric steam dump valves were used to maintained proper reactor |
| coolant system temperature.  The licensee said that they did not have any    |
| leaking steam generator tubes.  Proper steam generator water inventory was   |
| verified at which time the MSIS signal was reset, then one Motor Driven      |
| Auxiliary Feedwater Pump was manually initiated to maintain proper steam     |
| generator water level.   Main feedwater system isolated due to the MSIS      |
| signal and the reactor trip.  All emergency core cooling systems, emergency  |
| diesel generators are fully operable if needed.  The electrical grid is      |
| stable.  The licensee is investigating why the two additional steam dump     |
| bypass valves opened.                                                        |
|                                                                              |
| The NRC Resident Inspector was notified of this event by the licensee.       |
