A method of in-situ cleaning of a portion of a boiling water reactor nuclear power plant. In one aspect, the method includes identifying a jet pump for the boiling water reactor nuclear power plant for cleaning, providing an ultrasonic cleaning tool that has a transducer, inserting at least a portion of the transducer into or adjacent to the interior cavity of the jet pump, in-situ, and energizing the transducer to a desired energy level.

Ultrasonic jet-pump cleaner

A method of servicing a nuclear reactor during a reactor outage is provided. The reactor includes a primary containment vessel and a reactor pressure vessel positioned in the primary containment vessel. The method includes positioning a servicing platform above the reactor pressure vessel and performing predetermined servicing operations on the reactor. The servicing platform includes a frame having a plurality of interconnected beams, a support structure attached to the frame, and a floor attached to a top of the frame. The floor includes a reactor access opening sized to permit access to the reactor pressure vessel. The servicing platform also includes at least one auxiliary platform movably coupled to the frame and extending into the access opening. The at least one auxiliary platform is movable along a perimeter of the access opening of the floor.

Reactor servicing platform

A reactor servicing platform for a nuclear reactor is provided. The nuclear reactor includes a reactor pressure vessel positioned in a primary containment and at least one refuel bridge. The primary containment includes a refueling floor. The servicing platform, in an exemplary embodiment, includes a frame, a support structure, and a floor covering the frame. The floor includes a reactor access opening sized to permit access to the reactor pressure vessel.
