Problems solved by technology

The initial installation and subsequent replacement of the dosimetry system is difficult because space is usually limited in the area surrounding the reactor facility
Said difficulties are also exacerbated by the fact that this area is typically only accessible from areas below or above the reactor assembly
in addition, some difficulties are encountered in reliably locating dosimetry systems outside the container in a nuclear environment, since the dosimetry data obtained from the dosimetry system is only meaningful if the exact location of the dosimetry cassette is known

Abstract

An improved support apparatus is structured to support a dosimetry system within an interior region of a containment apparatus. The dosimetry system is supported in a region between an interior surface of the containment apparatus and an exterior surface of a reactor apparatus that is disposed within the interior of the containment apparatus. The support apparatus includes a retention apparatus having a plurality of brace elements that each have a receptacle formed therein. The receptacles are aligned with one another when installed within the interior of the containment apparatus. The support apparatus further includes a tube apparatus that includes a plurality of tube segments that are connectable together. The dosimetry system is situated within an elongated cavity formed in the tube apparatus. The tube apparatus is situated in the receptacles and thereby supports the dosimetry system on the containment apparatus.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to U.S. Provisional Patent Application No. 61 / 425811, entitled "Compact Bottom-Supported Ex-Vessel Neutron Dosimetry System," filed December 22, 2010 , which is incorporated herein by reference. technical field [0003] The disclosed and claimed aspects relate generally to nuclear power generation systems and, more particularly, to support equipment for supporting dosimetry systems in the vicinity of reactor facilities. Background technique [0004] As is generally understood in the related art, nuclear power plants typically employ a plurality of reactor facilities to generate thermal energy, which is in turn converted into electrical energy. As used herein, the word "plurality" and variations thereof shall refer broadly to any non-zero quantity, including a quantity of one. For safety and other reasons, it is often desirable to provide a plurality of dosimetry devices around the ext...
