EVENT TEXT

| REACTOR SCRAM FROM 100% POWER ON A FALSE LOW REACTOR WATER LEVEL INDICATION |
| |
| The Unit experienced an automatic reactor scram when an instrument line |
| "root" valve failed causing a water leak which resulted in a false low |
| reactor water level signal indication to be sensed by the RPS. The water |
| leak was immediately isolated by the ESF actuation of the Excess Flow Check |
| Valve in the same reactor instrumentation line. All rods fully inserted, no |
| ECCS injection occurred, no relief valves lifted and all safety systems |
| responded correctly. The plant also had actuation of the Primary |
| Containment Isolation System following the reactor scram. |
| |
| The NRC Resident Inspector will be notified. |

| THE ENS LINES, DIRECT LINES TO THE STATE, AND LOCAL COMMERCIAL LINES HAVE |
| BEEN CUT RESULTING IN THE LOSS OF THE USE OF THESE PHONE SYSTEMS. HOWEVER, |
| THEY DO HAVE OPERABLE FOREIGN EXCHANGE B/U PHONES AVAILABLE, SO THAT |
| EMERGENCY RESPONSE CAPABILITY IS NOT AFFECTED. THE TELEPHONE COMPANY IS |

| AUTOSTART OF ANNULUS EXHAUST GAS TREATMENT SYSTEM FAN DURING TESTING |
| |
| "During performance of surveillance testing, the lifting of an incorrect |
| lead caused a low flow condition on the in service AEGTS fan. This caused |
| the auto start of the standby AEGTS fan. No low flow alarm was received on |
| the in service fan, but the system functioned properly." |
| |
| The NRC resident inspector has been informed of this event by the licensee. |
