RTG's barring some MAJOR development in thermodynamics and material science are about as good as they can get power and safety wise.
RTG's just use a fancy heating element to convert heat to energy, a very old and very well understood property.
what i could see being tested are actual reactors like the ones nasa just showed off that are about the size of a coke can and apparently they are on
a path where they really believe megawatt powers in idiot proof space ready small reactors.
imagine on the way to mars you could have a set of actual reactors as well as solar to power your way there quickly with electric drives and power to
spare. it would even give you enough left over power to generate a powerful magnetic shell to help lower the radiation effects or even a particle
beam created bow shocks to repel charged particles out of the way
