That is definitely a very quick change! Looking at the Controls System docs, it looks like their example stores a const real & in the header. Right now, we have

  /// Power by which to normalize the OpenMC results, for k-eigenvalue mode
  const Real * _power;

  /// Source strength by which to normalize the OpenMC results, for fixed source mode
  const Real * _source_strength;

in include/base/OpenMCProblemBase.h. My C++ is a little rusty, but is declaring them as pointers alright instead of as a reference?

yep, you're totally right -- I was going too quickly! Do you want to give that a try to add?
