The First Stage in Digitizing the Expert Review of Software

One of the key duties of a nuclear safety authority is to ascertain the nuclear facility safety. Computational modeling of credible operational transients and accidents that may occur at a nuclear facility is imperative for demonstrating its nuclear and radiological safety. Software developers conduct a broad spectrum of computational and experimental research to demonstrate the computer code eligibility for modeling a certain facility – this procedure is usually referred to as ‘verification and validation’ of software. The outcome of the verification and validation process is reviewed by experts to confirm that the V&V has been performed as appropriate.
In the Russian Federation, the expert review of the software is a mandatory pre-licensing process that provides for an in-depth and comprehensive assessment of the calculation techniques used in the safety analysis. Furthermore, the review is conducted with the involvement of the Rostechnadzor’s Expert Board whose members are top computational modeling experts from SEC NRS, Rosatom organisations, national research centres, universities and Russian Academy of Science institutions.
