38. AERB SG D-25 and IEC 60880 for Certification of Software in Safety Systems of Indian NPP

In the nuclear domain, strict adherence to standards and guides is mandatory for safety–critical software. IEC 60880 standard provides requirements for the safety–critical (Class IA) software of the computer-based I&C systems. But, each country has its own guides that need to be followed for licensing/certification of safety–critical software. This work aims to bring out the essential regulatory requirements for certification of software for Class IA systems in Indian nuclear domain. Also, this work attempts to determine whether there are any additional regulatory requirements for certification of safety–critical software vis-à-vis adhering to the IEC 60880. Finally, this work attempts to identify the objectives, fulfillment of which can form the basis for certification of Class IA software.
