Track mounted steam generator man-way radiation shield door system

A radiation shield apparatus for a nuclear reactor for reducing a radiation exposure of a work as the worker performs maintenance or repair comprising:

• a) a shield assembly being a left half shield assembly and a right half shield assembly;
• b) the left half shield assembly and the right half shield assembly being able to roll in a same direction or in an opposite direction along the upper track member and the lower track member;
• c) the left half shield assembly and the right half shield assembly being secured together to close the man-way through a center draw latch;
• and
• d) the radiation shield apparatus being capable of being secured in a lock down configuration.

A method for reducing a radiation exposure of a worker as the worker performs maintenance or repair on a nuclear reactor comprising:

• a) removing a cover plate from a man-way of a nuclear reactor and exposing at least one stud aperture on a sealing surface;
• b) providing a track support frame with a top cross member, a bottom cross member, an upper track member, and a lower track member, with the top cross member having at least one alignment slot and the bottom cross member having at least one bottom aperture;
• c) securing at least one stud bolt in the at least one stud aperture;
• d) aligning the at least one alignment slot over the at least one stud bolt and firmly tightening the stud bolt in the at least one stud aperture;
• e) aligning the at least one stud bolt with the at least one bottom aperture and tightening the at least one stud bolt;
• f) attaching a right primary shield panel and a left primary shield panel with each having at least one roller to the top cross member with the at least one roller cooperating with the upper track member at an outer left edge and an outer right edge of the upper track member;
• g) providing a right angle steel and a left angle steel with the left angle steel securing to the left primary shield panel and the right angle steel securing to the right primary shield panel and each of the angle steels having the roller which cooperates with the lower track member;
• h) attaching a left side-panel and a right side-panel to the right angle steel and the left angle steel respectively;
• i) pivotally attaching a left adjustable secondary lower shield panel and a right adjustable secondary lower shield panel to the left primary shield panel and the right primary shield panel, respectively;
• and
• j) sliding a completed left half shield assembly and a right half shield assembly over the man-way with the working staying behind the left half shield assembly and the right half shield assembly.
