Abstract

The invention discloses a nuclear power station safety level software verification and validation method. The nuclear power station safety level software verification and validation method comprises the steps of establishing a nuclear power station safety level software verification and validation contrast list, wherein the contrast list comprises, at least, a basic file column, a verification file column and a suggestion feedback column; inputting function demand information of nuclear power station safety level software in the basic file column; verifying whether the function demand information can be satisfied by product function information; writing a verification result into the suggestion feedback column. In addition, the invention further discloses a nuclear power station safety level software verification and validation system. The nuclear power station safety level software verification and validation method and system achieves verification and validation at a nuclear power station safety level software concept phase and avoids the software failure risk caused by the fact that a safety software demander is inconsistent with a software provider on the aspect of conceptual understanding.

Description

technical field [0001] The invention belongs to the technical field of nuclear power, and more specifically, the invention relates to a method and system for verifying and confirming safety level software of a nuclear power plant. Background technique [0002] The instrument and control system of nuclear power plants is the central nervous system of nuclear power plants. It shoulders the important mission of controlling the normal operation of nuclear power plants and handling accidents, ensuring the safe and reliable operation of nuclear power plants under any working conditions. As computer systems are increasingly used in nuclear power plants, their importance to nuclear power plant safety is also increasing. This type of system is used not only in safety-related systems (such as process control and detection systems), but also in safety systems (such as reactor protection and ad hoc drives). The reliability of computer-based safety-important systems in nuclear power plan...
