Nuclear business management apprenticeship

Salaan aleikum
I can’t go to uni because of the haram student loan, so I’m looking for degree apprenticeships
A company that is moving me forward in the application process is called rolls Royce holdings, and the position is nuclear business management. The role involves working on the nuclear reactors on the Royal Navy submarine fleet - the nuclear reactors creates the fuel for the submarine to move. Is this halal, considering some submarines carry weapons some are nuclear deterrents, and they all belong to the Navy?
