| TURBINE POWER RUNBACK SIGNAL FROM REACTOR PROTECTION SYSTEM |
| |
| The unit received a runback signal from Overpower Delta T channels 3 and 4 |
| for 1.2 sec, during which time turbine reference power decreased from 90.7% |
| to 90.3%. Actual turbine load was manually reduced to lower reactor power |
| to 94% for increased margin to the runback. I&C personnel are investigating |
| why the signal actuated as there is no readily apparent reason. |
| |
| This report is required per the unit's procedures. |
| |
| The licensee plans to notify the NRC Resident Inspector and the Public |
| Service Commission for the State of New York. |

| |
| THE LICENSEE IS RETRACTING THIS REPORT BASED ON THE FOLLOWING: |
| |
| "Rochester Gas and Electric (RG&E) is retracting this event notification. A |
| turbine runback signal was listed in the unit's procedures as an RPS signal. |
| Upon further review, a turbine runback is not an RPS signal, and was |
| erroneously listed as such in the unit's procedures. The procedure has been |
| revised to delete a turbine runback as an RPS signal. Therefore, the |
| licensee has concluded that the event is not reportable. The NRC Resident |
| Inspector has been notified of this retraction by the licensee." |
| |
| NOTIFIED R1DO(CONTE). |

| AUTOMATIC REACTOR TRIP ON 2 OUT OF 3 OVERTEMPERATURE DELTA-TEMPERATURE |
| (OTdT). ALL RODS FULLY INSERTED INTO THE CORE. |
| |
| At 0854 CDT while swapping Main Feedwater Pump "1A" Main Feedwater Pump lube |
| oil coolers "1A" Main Feedwater Pump (MFW P "1A")tripped on low lube oil |
| pressure. Operators manually ramped back the Main Turbine to reduce reactor |
| power due to the loss of MFW P "1A". The Manual Main Turbine runback caused |
| both Pressurizer PORVs valves to open/close (open a few seconds) when |
| reactor coolant pressure increased to 2310 psig. The reactor tripped on a 2 |
| out of 3 Overtemperature Delta-Temperature trip signal at 0856 CDT (Manual |
| Main Turbine reduction in power was faster than the control rods reduction |
| in reactor power). All rods fully inserted into the core. Both Motor Driven |
| Auxiliary Feedwater Pumps started due to low Steam Generator Water Levels |
| (caused by the Main Turbine runback and the automatic reactor trip). |
| Currently Steam Generator Water Levels are being maintained by the operating |
| Motor Driven Auxiliary Feedwater pumps. No Code Safety valves on the |
| Primary or the Secondary side of the plant opened. No Steam Generator |
| Atmospheric Valves opened. Reactor Power level was between 77% to 82% |
| (Main Generator Power was at approximately 500 Mwe ) when the automatic |
| reactor trip occurred. The licensee initially entered EEP-0 (Safety |
| Injection/Reactor Trip procedure) performed the first 4 steps then entered |
| ESP-0.1 (Reactor Trip Response procedure) and after completing ESP-0.1 they |
| entered Unit Operating Procedure. |
| All Emergency Core Cooling Systems, Emergency Diesel Generators are |
| available, if needed. Offsite electrical power is stable. |
| |
| The licensee is investigating why Main Feedwater Pump "1A" tripped on low |
| lube oil pressure. |
| |
| The NRC Resident Inspector was notified of this event by the licensee. |
| |
| ***Update on 5/27/99 at 1352 EDT by Vaudy Holley taken by MacKinnon**** |
| |
| When the Pressurizer PORVs were opened it caused a reduction in the reactor |
| pressure to drop low enough for the Overtemperature Delta-Temperature |
| setpoints to be reached. This caused a reactor trip/turbine trip. |
| R2DO (Tom Decker) notified. The NRC Resident Inspector was notified. |

| - HOSPITAL DOSIMETER MEASURED A DOSE READING OF GREATER THAN 1000 RADS - |
| |
| AT 1430 ON 05/26/99, LYNN [LAST NAME UNKNOWN] EMPLOYED BY LANDAUER RADIATION |
| BADGE DOSIMETRY COMPANY, GLENWOOD, IL, REPORTED TO CHERYL SCHULTZ, RADIATION |
| SAFETY OFFICER (RSO), WILLIAM BEAUMONT HOSPITAL, ROYAL OAK, MI, THAT ONE OF |
| BEAUMONT HOSPITAL'S RADIATION DOSIMETERS MEASURED A DOSE READING OF GREATER |
| THAN 1000 RADS. THE RADIATION DOSIMETER IS A LUXEL ALUMINUM OXIDE FILMLESS |
| RADIATION DOSIMETER THAT HAS BEEN USED IN THE INDUSTRY SINCE THE FALL OF |
| 1998. THIS TYPE OF DOSIMETER HAS BEEN USED AT BEAUMONT HOSPITAL SINCE |
| JANUARY 1999. THE HOSPITAL MEDICAL TECHNOLOGIST WHO USED THIS DOSIMETER |
| WORKS IN A BLOOD BANK AND LAST USED A BLOOD IRRADIATOR IN APRIL 1999. THE |
| IRRADIATOR CONTAINS A SELF CONTAINED SEALED 10,000 CURIE CESIUM-137 |
| RADIATION SOURCE. |
| |
| THE HOSPITAL RSO STATED THAT THE IRRADIATOR IS FUNCTIONING PROPERLY AND THAT |
| THE TECHNOLOGIST DID NOT RECEIVE THIS HIGH DOSE. THE RSO FURTHER STATED |
| THAT HOSPITAL PERSONNEL HAVE NEVER RECEIVED GREATER THAN 0.06 MR/HR MAXIMUM |
| DOSE RATE WITH THE IRRADIATOR SOURCE EXPOSED. THE RSO BELIEVES THAT THE |
| DOSE READING IS INCORRECT OR THAT THE DOSIMETER SOMEHOW BECAME IRRADIATED. |
| THE DOSIMETRY COMPANY REPRESENTATIVE STATED THAT THE DOSIMETER READINGS WERE |
| OBTAINED TWICE AND THE DOSIMETER IS NOT DAMAGED. |
| |
| THE HOSPITAL RSO PLANS TO OBTAIN A BLOOD SAMPLE FROM THE TECHNOLOGIST AND |
| HAVE IT ANALYZED ON 05/27/99. |
