Abstract
Software V&V technology provides reliability and safety guarantee for digital system and intelligent equipment which used in nuclear power plant. Although a systematic scheme of software V&V technologies has been formed for nuclear power plant, there are some technical nodes need to be discussed and considered. The software V&V standard has been updated. The higher requirements are put forward for the depth, scope, the appropriate techniques and methods of the software V&V. This paper will discuss the upgraded version of software V&V related standards, and give the key points that software V&V technology needs to pay attention. Then the pre-development software identification, new software V&V technical of the special instrument and control system, and the applicability assessment of the safety analysis software are also been discussed. The technical difficulties faced by software V&V in the above aspects will be put forward. At last the future development direction of software V&V technology is proposed.
