Narrative:
We were flying a filed alternate routing due to extensive convective activity along our normal routing. While deviating left of course for weather; the first officer brought to my attention that the number one engine fuel shutoff valve circuit breaker had popped. Looking at the fire protection panel I noticed the fuel valve open light had extinguished. The first officer continued pilot flying (PF) duties and I immediately placed a call via satcom to the dispatcher and maintenance control. It was decided not attempt a reset of the breaker and divert the flight to a nearby airport. The remainder of the flight was uneventful and the passengers were deplaned at the gate. Maintenance met the aircraft at the gate; reset the popped circuit breaker; and found the shutoff valve to be continually cycling open and closed. Dispatch advised that a terminating light 15-20 minutes out and we should expect to swap into that aircraft to complete our flight. We re-dispatched on the alternate aircraft and completed the flight uneventfully.
