Abstract
Abstract A reactor vessel support is disclosed wherein the main coolant flow nozzles serve as vessel supports in addition to performing their primary function as conduits. The support nozzles are supplied with integral pads on their undersides which in cooperation with their normally large cross-sectional areas adequately sustain the static, dynamic, and thermal loadings, and thus render additional load bearing members unnecessary.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
75 words
In combination, a support structure having a well therein, a pressure vessel having a material capable of generating substantial heat therein whereby said vessel is subject to radial expansion, said vessel being substantially disposed within said well, coolant inlet nozzles and coolant outlet nozzles projecting outwardly and spaced about the peripheral wall of said pressure vessel, at least some of said nozzles bearing on surfaces of said well so as to support said pressure vessel.
Claim 2
Dependent Claim
75 words
In combination, a support structure having a well therein, a pressure vessel having a material capable of generating substantial heat therein whereby said vessel is subject to radial expansion, said vessel being substantially disposed within said well, coolant inlet nozzles and coolant outlet nozzles projecting outwardly and spaced about the peripheral wall of said pressure vessel, at least some of said nozzles bearing on surfaces of said well so as to support said pressure vessel.
Claim 3
Dependent Claim
36 words
The combination of claim 1 wherein said nozzles have integral pads and said well has a number of horizontal surfaces, said pads slidably bearing upon said horizontal surfaces whereby expansion of said pressure vessel is facilitated.
Claim 4
Dependent Claim
28 words
The combination of claim 2 wherein a ware plate having side shims supportedly receives said pads and cooling means are interposed between said pads and said horizontal surfaces.
Claim 5
Dependent Claim
24 words
The combination of claim 1 wherein conduits are affixed to said inlet and outlet nozzles, said conduits extending to the exterior of said well.
Claim 6
Dependent Claim
24 words
The combination of claim 1 wherein the well is constructed substantially of concrete and cooling means are interposed between the nozzles and the well.
Claim 7
Dependent Claim
98 words
In combination, a support structure having a well therein, a pressure vessel having a nuclear core therein and having a core-barrel contained therein; said core-barrel and said vessel forming a chamber therebetween, at least one inlet nozzle opening into said chamber, at least one outlet nozzle extending through said pressure vEssel and to the interior of said core-barrel, said inlet nozzle and said outlet nozzle extending radially outward from said pressure vessel in the same horizontal plane, said inlet nozzle and said outlet nozzle bearing on a surface of said well so as to support said pressure vessel.
Claim 8
Dependent Claim
98 words
In combination, a support structure having a well therein, a pressure vessel having a nuclear core therein and having a core-barrel contained therein; said core-barrel and said vessel forming a chamber therebetween, at least one inlet nozzle opening into said chamber, at least one outlet nozzle extending through said pressure vEssel and to the interior of said core-barrel, said inlet nozzle and said outlet nozzle extending radially outward from said pressure vessel in the same horizontal plane, said inlet nozzle and said outlet nozzle bearing on a surface of said well so as to support said pressure vessel.
