SUMMARY
The discussion centers on the feasibility of simulating a nuclear battery, specifically a radioisotope thermoelectric generator (RTG) using plutonium-238, with MCNP5. While MCNP5 is capable of modeling neutron and gamma transport, it is not suitable for simulating radioactive decay processes. For calculating thermal sources from Pu-238, hand calculations based on its mass, half-life, and energy release per decay are recommended. For temperature distribution analysis, a finite-element code designed for heat transfer is necessary.
