An investigation team was immediately formed to determine the cause of the Stop Valves closure.
The investigation is currently ongoing. The reactor was returned to power at 1047 on 6/17N4.

SUMMARY
OF OPERATING EXPERIENCE
]
June 1994 The unit began the month shutdown in mode 5 because of ongoing repairs to the number 7 Main Turbine Bearing. The bearing problem was detected on May 27,1994. The bearing repairs were completed on June 4,1994 and the unit was paralleled to the grid at 0954 on June 6,1994.
On June 12,1994 power reduction commenced at 1732 to allow repair of 11 Steam Generator Feed Pump oscillation problems. The problems were corrected and the unit began returning to full power j
at 0430 on June 13,1994.
1 On June 16,1994 the reactor tripped during an Operation weekly test of the Main Turbine Stop Valves. The trip occurred during the testing when all the Turbine Stop valves closed. The closure of the Turbine Stop valves tripped the Main Turbine and, subsequently, the Reactor. An investigation team was immediately formed to determine the root cause. On all subsequent tests the Turbine Stop -
Valves worked according to design. Vendor assistance was obtained to aide in determining the cause; their report is forthcoming. The unit was returned to power on June 17,1994 at 1047. The unit ended the month a 100% reactor power.
