Is it possible to do masters in nuclear engineering with a physics degree

It seems that lots of people do, so sure.

You might want to check out the admission requirements in nuclear engineering MSc programs that you're interested in. If it's not clear on the website whether your degree would be accepted, you can always contact the school directly.

 

I did, and I know a lot of other people who did, as well. But that was a long time ago, so Choppy's advice to check with the schools is a very good idea.

 

I would expect that you will likely find yourself needing to take some undergraduate fluids and heat transfer that were more application oriented than what you might have encountered in physics.
