Thanks Astronuc.
I actually was thinking about learning COMSOL multiphysics, but I didn't know if it would used as wide as others. I think that COMSOL uses CFDs, are there any other specific type programs that you recommend? I was also thinking about taking a course in numerical partial differential equations because I know this is evolved in finite element, would this be a benefit.
I don't know if Westinghouse uses Comsol in-house, but it would be beneficial to have that experience. Computational fluid dynamics (CFD) is one aspect of multiphysics. There are other packages, e.g. ANSYS, ABAQUS, and NASTRAN, which seem to be the most popular. They have evolved over the past three decades or so.
Other CFD packages included CFX (now owned by Ansys, and developed by AEA Technology) and STAR-CD. There is also Fluent, also owned by Ansys.

One should ask in one's department or other engineering departments (Nuc Eng, Mech Eng, Civ Eng, Aero Eng) about Multiphysics and CFD codes.
A course in numerical partial differential equations with some FEA would be highly beneficial. I did similar courses in grad school in which we studied the theory and developed our own CFD methods. That was before packages like CFX and STAR-CD were widely available. Now students use various CFD/Multiphysics packages, but it is important to know the theory, in order to know how to apply a method, and what it's limitations are.
The several principals in my company actually developed proprietary FEA methods from scratch, and so they know the bases of the methods, i.e. the physics behind the analyses.
I should also mention that with respect to the vendors (W, AREVA, Mitsubishi and GEH) of the Gen 3+ plants in the US, all have a reference fuel design in place. The fuel designs are based on currently operating fuel, particularly geometry and materials, so there is little room for substantial changes. One vendor is proposing something radically new, but that is still in the research (proof) phase.
The next generation (Gen 4) plants are still in R&D, and that is mostly handled by INL (DOE). There are numerous technical issues to be resolved, e.g. materials degradation and corrosion, under the proposed environmental conditions.
