<p>At some universities nuclear engineering is part of the Mechanical Engineering Department. A basic ME degree probably would cover all of the prerequisites for an MS in Nuclear except for any nuclear-specific classes that are not offered at your university. Keep in mind that your interest in nuclear may wane well before you finish your undergraduate degree. So, if you prefer chemical engineering then it may be best to major in chemical rather than ME and just choose your electives carefully so that you don’t close of the nuclear engineering option.</p>
