Internal, organic cold fusion engine

I have a creature that, thanks to its multiple, unique DNA chains, is impervious to cancer. So now I will move on to the next aspect: energy production.

This creature has two types of energy production methods: long-term, endurance energy, and short-term, sprint energy. The endurance energy is produced in the normal fashion: by eating food and digesting it. Endurance energy is used to power normal cellular functions, keep the heart beating, allow brain activity, etc.

Sprint energy, however, needs to be able to produce tremendous amounts of energy in a very short time, but doesn't need to be maintained for more than a few minutes at a time. Because my creature is impervious to cancer, I'm not worried about high-energy reactions causing harm to its cells. Since I like the unknowns in fringe sciences, I've settled on cold fusion as the engine for sprint energy.

However, nuclear physics isn't part of my knowledge set, so I'm asking the community the following two questions:

• How realistic is an internal, organic cold fusion engine?
• How would such an engine work?

I'm aware cold fusion is an oft-discredited field of science with many detractors claiming it's impossible, so cold fusion research doesn't get the same attention as the mainstream sciences. As such, I am not tagging this as either science-based or hard-science, but answers based in science are strongly preferred.
