专利汇可以提供Pressure vessel in particular for a nuclear reactor专利检索，专利查询，专利分析的服务。并且The invention is concerned with a pressure vessel of prestressed concrete, having an interior steel lining. A plurality of passages are provided in the concrete. If a leak occurs, the leaking pressurized fluid escapes through the porous concrete to said passages. The presence of the pressurized fluid in said passages can be checked by means of pressure gauges. The passages are preferably arranged as two separate sets of passages, the passages of one set forming an angle with those of the other set, making it possible to locate a leak fairly well.，下面是Pressure vessel in particular for a nuclear reactor专利的具体信息内容。

权利要求

1. A pressure vessel for a nuclear reactor, comprising a container consisting of pre-stressed concrete; a steel lining on the inside wall of said container; a plurality of channels in said pre-stressed concrete, said channels having porous walls for receiving fluid migrating through the pre-stressed concrete in the event of a leak in the steel lining; a plurality of pipes each pipe having one end communicating with said channels and the other end situated in a common chamber; a plurality of indicating members communicating with said channels and adapted to indicate the presence of fluid in said channels; a plurality of relief valves on said pipes in said common chamber to release fluid into said common chamber at a predetermined pressure; and a water-containing pressure-suppression tank in communication with said common chamber.

2. A pressure vessel as defined in claim 1, in which the channels are arranged in at least two groups, the channels in one group overlapping the channels of the other group, without communicating with the latter, and the channels in one group making an angle with the channels in the other group in order to enable the rupture in the steel liner to be pinpointed.

3. A pressure vessel as claimed in claim 1, in which the channels also contain the cables for pre-stressing the concrete.

4. A pressure vessel as claimed in claim 1, characterized in that the indicating devices consist of pressure-sensitive elements which are connected to each channel or group of channels.
