Nuclear reactor installation. [PWR]

Patent ·
OSTI ID:7212899
A nuclear reactor installation includes a pressurized-water reactor pressure vessel positioned in a reinforced-concrete structure forming a wall surrounding the pressure vessel and forming an annular space around the pressure vessel, this space containing a layer of discrete elements such as gravel, ceramic bodies, steel balls, etc. This layer directly contacts the concrete wall, possibly through a steel sheet or plate skin and between it and the pressure vessel, a thermally-insulating and pressure-resistant encasement is built from separable segments cast from suitable concrete, a steel sheet or plate skin preferably being interposed between the layer of discrete elements and this encasement, the discrete elements being compacted so that radial force transmitted from the pressure vessel via the encasement is transmitted through the discrete elements to the concrete wall formed by the reinforced-concrete structure.
