Abstract
A nuclear reactor plant with a light water reactor comprises a containment (1) having an upper space (2) and a lower space (3). The lower space is separated from the upper space by a separating member (4) and arranged to house a cooling medium (16). Furthermore, the plant comprises a reactor vessel (9) housing a reactor core (10) and provided in the upper space (2). The separating member (4) comprises a portion (7) which is arranged to be located at such a position that the surface portion (7) facing the lower space (3) is in contact with the cooling medium (16). The reactor vessel is provided above the portion (7).
Claims11
A nuclear reactor plant with a light water reactor, comprising a containment having an upper space and a lower space, which is separated from the upper space by a separating member and which is arranged to house a reservoir of a liquid cooling medium, and a reactor vessel housing a reactor core and located in the upper space,
- wherein the separating member comprises a portion which has a first surface facing the upper space and a second surface facing the lower space,
- wherein said portion is arranged at such a position that the second surface of the portion facing the lower space is in contact with said liquid cooling medium during normal operation of the plant,
- wherein the reactor vessel is provided above said portion,
- and wherein said second surface is arranged such that said liquid cooling medium may flow by natural recirculation along the second surface to remove heat from said portion.
