At approximately 0430 CDT on June 8, 2010, … At approximately 0430 CDT on June 8, 2010, during restoration following an addition of 10 gallons of hydrazine and a flush of 2 gallons of demineralized water to the Condensate Storage Tank (CST), a water-hydrazine mixture began to leak from check valve KHV0179. KHV0179 is a nitrogen supply check valve that can also be used for hydrazine addition.</br>Chemistry technicians estimated that a water-hydrazine mixture on the order of 2 gallons leaked through KHV0179 before the line could be isolated. Samples taken from the atmosphere above the spill contained 0.25 ppm hydrazine. The fluid on the ground was measured to contain 15% hydrazine.</br>The Department of Natural Resources (DNR) was notified of this event at approximately 1000 CDT on June 8, 2010.</br>The Nuclear Regulatory Commission (NRC) Resident Inspectors will be notified.NRC) Resident Inspectors will be notified. +
