Title: Ultrasonic decontamination robot

Abstract

A method is described of removing radioactive contamination from a primary fluid header of a steam generator between periods of active operation thereof, the header having a sealable access manway therein to permit access to interior surfaces of the header. The method consists of: inserting through the header manway into the interior thereof a robotic arm having a base portion sized to fit sealably in the manway, an ultrasonic decontamination head disposed to be movable at an end of the robotic arm, a solvent supply tube connected to the decontamination head, and a fluid removal conduit disposed at a low point in the interior of the header; sealing the base portion in the header manway.
