EVENT TEXT

| REACTOR TRIP FROM 100% POWER ON BOTH UNITS DUE TO TURBINE TRIP ON BOTH |
| UNITS |
| |
| The licensee reported that a loss of power on the 345KV grid caused a |
| turbine trip on both units which resulted in a reactor trip from 100% on |
| both units. All rods fully inserted and no ECCS was actuated. Both units |
| are currently at Mode 3 in natural circulation and stable. The auxiliary |
| feed water systems started on both units to maintain steam generator levels. |
| The reactor coolant temperature is being controlled by using the steam |
| generator atmospheric relief valves. Since the safety systems were powered |
| by an alternate offsite power supply, the 4 emergency diesels did not auto |
| start, but they are operable. The licensee is investigating why they lost |
| the 345KV grid. |
| |
| |
| The NRC Resident Inspector was notified. |

| TRANSPORTATION INCIDENT |
| |
| The National Response Center sent a fax to the Operations Center regarding |
| the following transportation incident: |
| |
| A tractor trailer carrying the reactor vessel head from North Anna power |
| plant to EnviroCare in Clive, UT was sideswiped by a pickup truck being |
| driven by a drunk driver near Kingman, KS on Route 42. The pickup truck |
| passed the tractor trailer at approximately 80 mph, and proceeded down the |
| road, where it was involved in a traffic accident. The incidental impact |
| between the pickup and the tractor trailer caused a minor tear in the |
| protective tarp and plastic container containing the vessel head, along with |
| depositing some paint on the head itself. There was no apparent structural |
| damage to the vessel head, and no apparent radioactive release into the |
| atmosphere. |
| |
| The truck driver stopped his vehicle in Greensburg, Kansas to assess the |
| condition of the vessel head. The shipper is sending a representative to |
| inspect the packing material integrity. The state of Kansas will also be |
| sending a representative out to the scene to assist. |
