- 15,000 GALLON MINING INJECTION SOLUTION SPILL -
A WELLFIELD MINING INJECTION SOLUTION ("BARREN LIXIVIANT") SPILL OCCURRED AT THE IN-SITU LEACH INJECTION MINE UNIT 5 (#5BD47-1) AT THE CHRISTENSEN MINE IN CAMPBELL COUNTY, WY.
THE SPILL, WHICH IS ESTIMATED TO BE 15,000 GALLONS WITH A URANIUM CONCENTRATION OF
1.0 mg/I OF U3O8, IS THE RESULT OF A PLUMBING FAILURE AT THE INJECTION WELL HEAD. THE SPILL WAS REPORTED TO THE NRC SINCE IT IS GREATER THAN 10,000 GALLONS, WHICH IS CONSIDERED SIGNIFICANT FROM AN OPERATIONS STANDPOINT.
THE SOLUTION SPILLED ONTO THE NEARBY SOIL AND IT IS ANTICIPATED THAT THE SPILL DOES NOT POSE A HEALTH OR ENVIRONMENTAL HAZARD DUE TO ITS LOW CONCENTRATION OF URANIUM. THERE ARE NO RESIDENTS WITHIN ONE MILE OF THE SPILL AND THE NEAREST TOWN IS FURTHER THAN 15 MILES AWAY.
THE INJECTION WELL WAS SHUT DOWN AND THE SPILL WAS STOPPED. THE WELL WILL NOT BE USED UNTIL THE PLUMBING IS REPAIRED. A SOIL SAMPLE HAS BEEN COLLECTED AT THE SPILL LOCATION AND WILL BE ANALYZED FOR THE PRESENCE OF Ra-226 TO DETERMINE IF SOIL CLEAN-UP IS NECESSARY.
THE RADIATION SAFETY OFFICER (RSO) PLANS TO NOTIFY THE WYOMING STATE DEPARTMENT OF ENVIRONMENTAL QUALITY AND PLANS TO SUBMIT A WRITTEN REPORT TO THE NRC WITHIN 7 DAYS.
HOO NOTE: SEE SIMILAR EVENTS #35524, #35542 AND #35593.

MANUAL REACTOR SCRAM FROM 100% POWER DUE TO SJAE HIGH PRESSURE ISOLATION.
CONTROL ROOM OPERATORS MANUALLY SCRAMMED THE REACTOR FROM 100% POWER DUE TO A STEAM JET AIR EJECTOR (SJAE) HIGH PRESSURE ISOLATION. THE CAUSE OF THE ISOLATION IS UNKNOWN AND BEING INVESTIGATED. ALL CONTROL RODS FULLY INSERTED AND NO ECCS INJECTIONS OCCURRED. THE PLANT ALSO RECEIVED A PRIMARY CONTAINMENT ISOLATION (PCI) SYSTEM GROUP 1 (MSIVs CLOSED), GROUP 2 (TORUS AND DRYWELL VENTS) AND GROUP 3 (RWCU SYSTEM) ISOLATIONS. ONE SRV CYCLED OPEN AND CLOSED PROPERLY. HOWEVER, A SECOND SRV INDICATED HIGH TAIL PIPE TEMPERATURE. THE LICENSEE IS INVESTIGATING THIS CONDITION.
THE LICENSEE PLANS TO INFORM THE NRC RESIDENT INSPECTOR.
* * * UPDATE AT 1035 ON 05/09/99 BY PAT DECKER TO JOLLIFFE * * *
DURING THE SRV OPENING AND CLOSING, THE PLANT RECEIVED A PCI SYSTEM GROUP 3 (RWCU SYSTEM) ISOLATION SIGNAL FROM THE REACTOR VESSEL WATER LEVEL DROPPING BELOW 9 INCHES.
THE LICENSEE PLANS TO INFORM THE NRC RESIDENT INSPECTOR.
