Abstract
A multi-sensor radiation detection system for removable insertion into a nuclear reactor wherein one conductor of all the sensors is a single, common element. This single common element is contained within a tubular metallic sheath and in cross-section comprises a multiple radial armed metallic conductor having a star shaped cross-section dimensioned to form wedge-shaped compartments throughout the active radiation detecting length of the metallic sheath.
Claims8
A multiple sensor radiation detection device for insertion into a nuclear reactor comprising:
- an outer tubular sheath member;
- an electrically conducting member having a crosssection comprised of a plurality of radially extending arms joined at their center, said conducting member having a crosssectional diameter substantially equal to the inner diameter of said sheath;
- said electrically conducting member being inserted into said sheath member so as to divide the interior volume of said sheath member into a plurality of volumes having a generally wedge-shaped cross-section extending axially long said sheath;
- and
- at least two radiation sensors each of which is located within a respective one of said volumes of wedge-shaped cross-section and spaced from said electrically conducting member by a dielectric whereby said electrically conducting member is a common conducting member for each radiation sensor.
