Abstract
Abstract The Nuclear Power Plant Containment Construction includes the spherical steel safety enclosure for the reactor and the equipment associated with the reactor and requiring this type of enclosure. This steel enclosure is externally structurally protected against accident by a concrete construction providing a foundation for the steel enclosure and having a cylindrical wall and a hemispherical dome, these parts being dimensioned to form an annular space surrounding the spherical steel enclosure, the latter and the concrete construction heretofore being concentrically arranged with respect to each other. In the disclosed construction the two parts are arranged with their vertical axis horizontally offset from each other so that opposite to the offsetting direction of the concrete construction a relatively large space is formed in the now assymetrical annular space in which reactor auxiliary equipment not requiring enclosure by the steel containment vessel or safety enclosure, may be located outside of the steel containment vessel and inside of the concrete construction where it is structurally protected by the latter.

Claim 3
Dependent Claim
75 words
The installation of claim 1 in which said spherical steel enclosure has an air-tight materials'' lock projecting therefrom into a portion of said enlarged area of said annular space but remaining entirely inside of said cylindrical wall of said concrete construction, said cylindrical wall having an opening for access to said lock and having a closure for said opening, said wall of said concrete construction and said closure protecting said lock against externally caused damage.
Claim 4
Dependent Claim
60 words
The installation of claim 1 in which a steam line extends from said steam generator air-tightly through said spherical steel enclosure and through said cylindrical wall of said concrete construction, in a direction opposite to said offset and in which direction said annular space has a reduced area because of said offset and which is spanned by said steam line.
Claim 5
Dependent Claim
34 words
The installation of claim 3 in which said steam line is enclosed by a steam line rupture protection jacket which extends from said spherical steel enclosure to said cylindrical wall of said concrete construction.
Claim 6
Dependent Claim
70 words
The installation of claim 1 in which a portion of said enlarged area of said annular space, forms a fuel element loading station inside of said cylindrical wall of said concrete construction, said spherical steel enclosure having a fuel element lock extending horizontally therethrough for the endwise passage of fuel elements to said loading station, and said loading station having means for rotating fuel elements between vertical and horizontal positions.
Claim 7
Dependent Claim
33 words
The installation of claim 5 in which an opening for said loading station is formed through said cylindrical wall, and said opening has means for protecting said loading station against externally caused damages.
Claim 8
Dependent Claim
54 words
The installation of claim 1 in which said concrete construction forms in said enlarged area of said annular space, at least one room with a concrete wall spaced from said spherical steel enclosure so as to leave a portion of said annular space accessible to personnel, said room containing material which is possibly radioactive.
