This paper is an attempt to assess Indian nuclear security architecture in the light of recurrent Indian nuclear security incidents and their impact on national regional and global non-proliferation efforts. India is one of the significant global nuclear energy markets for Russia and US alike. Nevertheless, nuclear safety and security incidents including uranium thefts in India have increased concerns regarding Indian nuclear security architecture. The study utilizes International Nuclear Security Framework to assess the Indian nuclear security architecture. This research aims to analyze Indian nuclear safety and security measures by exploring Indian uranium theft incidents, nuclear security lapses and over all gaps in Indian nuclear security architecture. Through this analysis, the study explores Indian nuclear credentials and its adherence to global nuclear nonproliferation standards and norms. This study further investigates how such incidents impact Indian nuclear credentials vis-à-vis global nuclear governance and provides recommendations for India to enhance its nuclear security infrastructure to reduce the risk of such incidents thereby, enhance its nuclear non-proliferation credentials.
