hey..Could you please tell me about the scope of nuclear engineering after 5 years or so?Also, will IITs provide the same knowledge and skills as other Institutes in the world?If yes, Which IIT will be the best for Nuclear Engineering courses?

Nuclear Engineering and Nuclear Physics has a great scope even today and it is a very vast field. Whether IIT would be good or not depends on what do you want to do. I mean, If you are asking for graduation, that is a BTech or Int MSc, IIT is the best instituite. Also If you want to go for research, then, IISER and IISc are the best Research institutes in India. But If you are asking for a Phd or MS, no doubt a foreign university will be a better option.
