Arrangement structure of nuclear power station

Abstract

The invention provides an arrangement structure of a nuclear power station. The arrangement structure comprises a nuclear island, the conventional island, and a first span structure positioned between the nuclear island and the conventional island, wherein equipment and a pipeline in a transition section between the nuclear island and the conventional island are arranged in the first span structure. The arrangement structure reduces the construction cost of the whole nuclear power station and workload during safety assessment.

Description

technical field [0001] The invention relates to an arrangement structure of a nuclear power plant. Background technique [0002] With the development of nuclear energy technology, the application of nuclear power is becoming more and more extensive. In order to ensure the safety of nuclear power, various measures are usually taken based on the concept of defense in depth. Defense in depth refers to a multi-level defense system established in consideration of failures in technology and organizational management. The principle of defense in depth is a safety design concept that runs through all production activities of a nuclear power plant throughout its life cycle (including decommissioning). All layers of defense must be effective, and each layer must be considered as the last barrier. The design of a nuclear power plant must recognize that all levels of defense in depth may be tested and must therefore provide measures to ensure that its safety objectives are achieved. ...
