Abstract
Abstract The nuclear power station is constructed so that a working gas is conducted through a closed cycle. The reactor, power station and heat exchangers are accommodated in a pressure tight vessel while the starting point and end point of the working gas thermal work path are disposed in a sub-chamber with the power station.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
39 words
A nuclear power station as set forth in claim 1 wherein said heat exchangers are disposed in said second chamber and wherein an intermediate floor is disposed in said second chamber to separate said second chamber into two parts.
Claim 2
Dependent Claim
34 words
A nuclear power station as set forth in claim 2 wherein a first part of said twO parts contains said power plant and a second part contains at least some of said heat exchangers.
Claim 3
Dependent Claim
28 words
A nuclear power station as set forth in claim 3 wherein said heat exchangers include a plurality of re-coolers mounted in said intermediate floor at said end point.
Claim 4
Dependent Claim
67 words
A nuclear power station as set forth in claim 3 wherein said heat exchangers include a plurality of recuperators mounted in said second part for cooling a flow of the working gas and a plurality of re-coolers mounted in said intermediate floor at said end point and connected to said recuperators to further cool the flow of working gas passing from said recuperators to said power plant.
Claim 5
Dependent Claim
36 words
