Abstract

Abstract A reactor installation has a pressurized-water reactor pressure vessel with its bottom fixed against downward movement and an upper portion which connects via a horizontal straight coolantloop pipe, with the lower portion of a vertical steam generator horizontally offset from the pressure vessel and positioned at a higher level than the latter. The bottom of the steam generator is supported by a cam follower which rides on a fixedly positioned cam surface which inclines upwardly away from the pressure vessel. With varying temperatures the pressure vessel expands and contracts vertically so that its upper portion moves up and down, but the pressure vessel also radially expands and contracts and the coolant pipe does likewise in its longitudinal or axial direction, the resulting horizontal motions being transmitted via the end of the coolant pipe connected with the steam generator to the latter, the cam angularity being such that the steam generator is displaced horizontally and vertically in such a manner that the coolant pipe remains substantially horizontal and free from compressive stress other than that required to move the steam generator via the cam follower fixed to its bottom, through up and down motion on the inclined cam surface.

Claims Analysis

Total Claims: 9
Claim 1
Independent Claim 120 words
A reactor installation comprising a vertical reactor pressure vessel having a bottom fixed against downward movement and an upper portion, a vertical steam generator horizontally offset from said vessel and having a lower portion substantially at the level of the vessel''s said upper portion and a bottom, a support for the generator''s said bottom, and a substantially straight and horizontal coolant pipe having a first end fixed to the vessel''s said upper portion and a second end fixed to the generator''s said lower portion; wherein the improvement comprises said support comprising a fixedly positioned cam surface which inclines upwardly away from said vessel, and a cam follower for said cam surface and which is fixed to the generator''s said bottom.
Claim 2
Dependent Claim 120 words
A reactor installation comprising a vertical reactor pressure vessel having a bottom fixed against downward movement and an upper portion, a vertical steam generator horizontally offset from said vessel and having a lower portion substantially at the level of the vessel''s said upper portion and a bottom, a support for the generator''s said bottom, and a substantially straight and horizontal coolant pipe having a first end fixed to the vessel''s said upper portion and a second end fixed to the generator''s said lower portion; wherein the improvement comprises said support comprising a fixedly positioned cam surface which inclines upwardly away from said vessel, and a cam follower for said cam surface and which is fixed to the generator''s said bottom.
Claim 3
Dependent Claim 41 words
The installation of claim 1 in which the incline angularity of said cam surface is determined substantially by the ratio of the distance between the pressure vessel''s said bottom and the axis of said pipe, to the length of said pipe.
Claim 4
Dependent Claim 15 words
The installation of claim 2 in which said incline angularity is from 15* to 25*.
Claim 5
Dependent Claim 21 words
The installation of claim 1 in which at least one anti-friction rolling element supports said cam follower on said cam surface.
Claim 6
Dependent Claim 25 words
The installation of claim 1 in which said support is offset from the vertical axis of said generator in a direction away from said vessel.
Claim 7
Dependent Claim 79 words
The installation of claim 1 in which two of said supports are provided for the generator''s said bottom and said two supports are symmetrically spaced on either side of the axis of said pipe and with respect to the vertical axis of said generator, and the longitudinal axes of the said cam surfaces of said two supports in vertical planes converge towards the pipe''s axis in a direction towards said vessel, said pipe''s axis intersecting said generator''s vertical axis.
Claim 8
Dependent Claim 27 words
The installation of claim 6 in which the angle at which said cam axes converge is about from 5* to 6* with respect to said pipe''s axis.
Claim 9
Dependent Claim 30 words
The installation of claim 6 in which said followers of said two supports, have anti-friction rolling element on which they are supported on said cam surfaces of said two supports.
