Abstract
Abstract A nuclear reactor with a heat extraction system comprising two groups of heat pipes which extend through the reactor core and which deliver heat to heat sinks disposed outside the core. All pipes of one group being parallel, the two groups are arranged in a mutual right angle relation and they intersect each other.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
85 words
A nuclear reactor with a heat extraction system comprising a plurality of hermetically sealed heat pipes, which extend through the core zone and are mechanically held by means of thermal and electrical insulators in the zone of a reflector surrounding the core zone, the heat pipes being subdivided into two groups with axial orientations of the heat pipes of one group disposed at an angle relative to the heat pipes of the other group and axes of the two groups intersecting in the core zone.
Claim 2
Dependent Claim
85 words
A nuclear reactor with a heat extraction system comprising a plurality of hermetically sealed heat pipes, which extend through the core zone and are mechanically held by means of thermal and electrical insulators in the zone of a reflector surrounding the core zone, the heat pipes being subdivided into two groups with axial orientations of the heat pipes of one group disposed at an angle relative to the heat pipes of the other group and axes of the two groups intersecting in the core zone.
Claim 3
Dependent Claim
61 words
A nuclear reactor according to claim 1, in which the nuclear fuel comprises substantially cube-shaped elements of which each is provided with two bores containing heat pipes disposed orthogonally to each other and parallel to two of the principal axes of the cube the elements in the core being stacked with the bores of the elements in alignment with each other.
Claim 4
Dependent Claim
51 words
A nuclear reactor according to claim 1, in which the diameters of the reactor core bores for the heat pipes are substantially larger than the external diameters of the heat pipes, so that there is clearance between the heat pipes and the walls of the bores in which they are received.
