Digital technology has been widely used in safety instrument and control (I&C) system of nuclear power plant (NPP). In order to guarantee high quality requirements about the safety I&C system of NPP, software Verification and Validation (V&V) should be implemented according to the standard IEEE 1012-2004. Software requirements evaluation would be done in different activities of software V&V. Even if the main tasks has been given in IEEE 1012-2004, the study about the evaluation methods is necessary to make progress in the implementation. Based on the practice about YangJiang units 5 and 6 projects, which is a Generation II+ pressurized water reactor, this study illustrates the software requirements evaluation methods of safety I&C system related to the laws and regulation standards. The system with evaluation indexes has been established which is also used in the practice of software V&V. Finally the effect has been analyzed from the process of V&V activities in the software development process. As a result, the analysis is also benefit to the design, development, operation and maintenance of safety I&C System as technical references in NPP.
