Abstract
Abstract A control rod for a nuclear reactor in an articulated form, and including a series of pivotally connected links. At least one of these links is disclosed, the endmost one, serves as a means for the collection of a gas, with the rest of the links containing a neutron absorbing material. Flexible members extend through pivotal joints between the links, establishing serial communication between the links and serving to convey the gas produced as a result of the absorption of neutrons by said material into said gas collection means.

Claim 1
Independent Claim
110 words
A control rod for a nuclear reactor, accommodated in the core of said reactor and comprising: a series of hollow links; pivotal joints interconnecting said series of links into an articulated structure; at least one of said links of said series, which is the endmost one, serving as a gas collecting means; a neutron absorbing material accommodated in the rest of said links of said series; flexible members extending through said pivotal joints and establishing serial fluid communication between said links, with said flexible members being adapted to convey the gas produced as a result of the absorption of neutrons by said neutron absorbing material to said gas collecting means.
