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.

A work platform includes a first elongate side section, a second elongate side section, and a floor section. The first and second side sections each includes a lower beam, an upper beam, and a plurality of support members extending between and coupled to the upper and lower beam. The floor section includes a plurality of cross beams extending between and coupled to the first and second side sections, and a floor panel supported by the cross beams. The work platform also includes a crane assembly movably coupled to the first side section. The crane assembly is longitudinally movable along first side section. The upper beams, lower beams, support members, cross beams, floor panel, and the crane assembly are fabricated from fiber reinforced plastic.
