| JULIE FELICE OF THE UTAH DIVISION OF RADIATION CONTROL RECEIVED A REPORT |
| FROM THE RADIATION SAFETY OFFICER (RSO), FOR SUNRISE ENGINEERING INC., THAT |
| A TROXLER MOISTURE DENSITY GAUGE HAD BEEN STOLEN ON 05/30/96 AT 1730 EDT. |
| |
| THE RSO FOR SUNRISE ENGINEERING INC., LOCATED IN FILLMORE, UTAH, REPORTED |
| THAT A TROXLER MOISTURE DENSITY GAUGE HAD BEEN STOLEN FROM THE BACK OF ONE |
| OF THEIR PICKUP TRUCKS LOCATED AT THEIR DRAPER, UTAH OFFICE. THE TROXLER |
| MOISTURE DENSITY GAUGE HAD BEEN CHAINED AND LOCKED IN THE BACK OF THE |
| PICKUP TRUCK. SOMEONE USED A CHAIN CUTTER TO STEAL THE TROXLER MOISTURE |
| DENSITY GAUGE. THE MODEL # OF THE DENSITY GAUGE IS 3430 AND ITS SERIAL # |
| IS 23008. THE SOURCES IN THE GAUGE WERE 8 mCi OF Cs-137 (SERIAL # FOR THE |
| CESIUM SOURCE IS 75-4813), AND 40 mCi OF Am(241)-Be (SERIAL # FOR THE |
| Am(241)-Be SOURCE IS 47-18815). LICENSEE NOTIFIED THE SALT LAKE CITY |
| POLICE DEPARTMENT OF THE STOLEN TROXLER MOISTURE DENSITY GAUGE AND THE |
| POLICE CASE # FOR THIS THEFT IS 96-71082. THE UTAH DIVISION OF RADIATION |
| CONTROL WILL TRY TO HAVE THE LOCAL NEWS STATIONS ANNOUNCE THAT A TROXLER |
| MOISTURE DENSITY GAUGE WAS STOLEN. |

| MANUAL REACTOR TRIP FROM 73% POWER DUE TO UNEXPECTED HIGH MAIN TURBINE |
| VIBRATION |
| |
| While the licensee was in the process of increasing load after exiting a |
| refueling outage, vibrations on the #1 and #2 bearings for the main turbine |
| were noted to be increasing unexpectedly. As a result, operators began to |
| decrease load at 0036 on 05/18/99 with the unit at approximately 83% reactor |
| power. Operators manually tripped the reactor from 73% power at 0041. At |
| that time of the manual reactor trip, vibrations on the #1 and #2 bearings |
| were at a level of about 10� mills and 12 mils, respectively. The limits on |
| vibration are either 10 mils for 15 minutes or when a vibration of 12 mils |
| is reached. |
| |
| All control rods fully inserted as a result of the manual reactor trip, and |
| all systems functioned as required. There were no engineered safety feature |
| actuations or emergency core cooling system injections, and none were |
| required. |
| |
| The unit is currently stable in Mode 3 (Hot Standby). The reactor coolant |
| pumps, normal charging and letdown, and pressurizer heaters and sprays are |
| being utilized for primary system transport, level, and pressure control. |
| All containment parameters are normal. Emergency feedwater was manually |
| initiated and is currently supplying water to the steam generators. |
| Secondary steam is being dumped to the condenser. Offsite power is |
| available, and the emergency diesel generators and emergency core cooling |
| systems are operable and available if needed. |
| |
| The licensee notified the NRC resident inspector. |
| |
| * * * UPDATE AT 1545 BY PROPPER, TAKEN BY WEAVER * * * |
| |
| "The cause of the high vibrations experienced on May 18 were attributed to |
| light rubbing within the new mono-block high turbine rotor. The HP Turbine |
| initial vibration readings were less then 2 mils during rollup through the |
| critical speeds when packing rubs would normally be identified. No rubs were |
| identified prior to the 83% power level. |
| |
| "While increasing power well within the prescribed limits for power |
| increases, it is believed that the opening of the #4 control valve at |
| approximately 83% power caused a thermal transient in the HP Turbine. The |
| thermal transient resulted in slightly uneven heating and growth of the |
| turbine casing. |
| |
| Actions taken to preclude this event prior to restart included: |
| |
| Greasing of the HP turbine skids to allow unrestricted shell casing growth |
| |
| Changed setting on the MSR digital controls system which placed the MSR in |
| pressure mode prior to 75% load. Ensuring that the MSR controls were at 100% |
| open on the high range valve at 75% reactor power. |
| |
| Decreased the rate of power change at the #4 control valve crack point to |
| 1.5% per hour to allow more time for thermal expansion of the HP Turbine. |
| |
| "The net result was that the unit increased power uneventfully upon restart |
| at 0207 on 5/19/99, with breaker closure at 0225. The #4 control valve |
| started opening at 89% power at 0809 on 5/20/99. The plant is currently at |
| 98% power and awaiting engineering review prior to increasing to 100%." |

| MISSING RADIOACTIVE LIQUID REAGENT CONTAINING 80 MICROCURIES OF IODINE-125 |
| |
| Sometime between May 3rd and May 5th, 80 �Ci of Iodine-125 was discovered |
| missing from the walk in freezer in the Neonatal Hypothyroidism Lab in the |
| Maryland Lab Administration Building. The I-125 was in 10 bottles of 8 �Ci |
| each and in the form of a liquid used as a tracer reagent. It is unknown |
| whether the I-125 was stolen or disposed of and it is still being |
| investigated at this time. The Department of General Services Police were |
| notified and are part of the investigation. |
| |
| This constitutes minimal threat to the general public. |

| MOISTURE DENSITY GAUGE DAMAGED DURING TRAFFIC ACCIDENT |
| |
| A Campbell Pacific moisture density gauge was damaged when the pickup in |
| which it was secured was involved in a traffic accident. The gauge broke |
| loose during the accident and was ejected from the truck. A company |
| representative went to the site and surveyed the gauge, which was locked |
| with the case intact. Surveys performed at the crash site indicated no |
| contamination resulted from this incident. |
| |
| The gauge contains approximately 10 mCi of Cs-137 and 50 mCi of Am-241. |

| OFFSITE NOTIFICATION - CONTAMINATION FOUND ON THE EQUIPMENT HATCH STORAGE |
| RACK |
| |
| The licensee notified Lower Alloways Creek Township of the following event. |
| |
| "Radiation Protection supervision notified the on-duty Operations |
| Superintendent that smearable (loose) contamination was found on a storage |
| rack which was purchased to store the temporary equipment hatch used at |
| Salem. The storage rack has never been in the RCA and has not been in |
| contact with any licensed radioactive material. Initial investigation |
| indicates that the source of the contamination is the paint. Isotopic |
| analysis of the smears and paint chips removed show Bi-214 and Pb-214, both |
| particulate daughters in the uranium decay chain. No isotopes have been |
| identified which are attributable to the plant isotopic mix (I.e.,- |
| corrosion or fission products). |
| |
| "Survey results were 10,000 dpm per standard probe area for a large area |
| smear. |
| |
| "The storage rack is located in a fenced, locked area." |
| |
| The licensee notified the NRC resident inspector. |
