Robinson Generating Station, Unit 2 experienced a failure during post maintenance testing of a newly installed air conditioning compressor, which serves one of the Control Room HVAC units. Robinson plant contacted QualTech (the supplier) on September 22, 2020, detailing the findings of their investigation which indicated an incorrect head gasket had been installed, allowing high pressure gas to discharge to the low pressure side. </br>QualTech NP reviewed the investigation and agrees, the incorrect gasket was installed. The root cause was determined to be an improper dedication plan of the gaskets, not recognizing the delta between the 'left' and 'right' head gaskets. QualTech has taken action to revise the dedication plan. This is the only compressor unit of this model sold. No other similar failures have been reported. QualTech believes this to be an isolated case.</br>For further information contact: </br>Tim Franchuk</br>Quality Assurance Director </br>QualTech NP, Curtiss-Wright Nuclear Division </br>(513) 528-7900 x176ight Nuclear Division
