1. A modular stationary nuclear boiler including: a nuclear reactor;  at least one steam generator connected to said reactor;  a metal casing housing said reactor and said generator;  and auxiliary boiler equipment;  the improvement comprising:  prefabricating and testing a horizontally transportable reactor unit at a fabricating site, said reactor unit including a casing containing a nuclear reactor, at least one steam generator connected thereto and a horizontally transportable support which insures its stability during both operation and transport;  prefabricating and testing a horizontally transportable container unit at the fabricating site, said container unit comprising walls housing auxiliary equipment for the nuclear reactor and said at least one steam generator and deliminating a closed internal chamber having a closable opening within one of the sidewalls thereof;  prefabricating and testing a horizontally transportable closing component for the opening in said container unit, at the fabricating site;  loading said support borne reactor unit, said container unit and said closing component by horizontal transport from the fabricating site onto a barge;  bringing said barge by water to the final operating site for the modular nuclear boiler;  unloading said container unit from said barge by horizontal transport of the container unit from said barge to said final operating site;  unloading said reactor unit from said barge by horizontal transport of said reactor unit from said barge to said final operating site of the boiler and horizontally inserting it in the nuclear container unit by lateral passage through said opening; and  unloading said closing component by horizontal transport of said closing component from said barge to said final operating site and by horizontal passage into said container unit opening to close off said opening and to effect complete containment of said reactor unit by said transportable container unit and said closing component in modular fashion. 2. A nuclear boiler according to claim 1, wherein said closing component contains a swimming bath type storing unit for the used fuel elements. 3. A method of assembly of a modular nuclear boiler on a stationary final operating site, said method including the following steps:
