I know this will sound like a newbish question. Today I was at my AFCO and we were going over what the best option for me was, and we decided Marine Engineering Submariner was best. He mentioned to me that I would end up working with the nuclear reactor and such. He did mention nuclear to me a good few times. I am aware I should have listened more intently, but I will ask here. Does working with nuclear happen to all marine engineers, or is it a further specisalition?
