Somehow I stumbled on the exact PDF you want to see: http://www.nasa.gov/pdf/604332main_APP%20MSL%20Launch%20Nuclear%20Safety%20FS%203-2-11.pdf http://www.nasa.

- ilamont 14y agoThanks. The relevant bits: Like previous generations of this type of electrical- power generator, the MMRTG is built with several layers of protective material designed to contain its plutonium dioxide fuel in a wide range of po- tential accidents, verified through impact testing. Each MMRTG carries eight individually shielded general purpose heat source modules (compared to 18 modules in the previous generation). The thickness of the protective graphite material in the center of the modules and between the shells of each module in the MMRTG has been increased by 20 percent over previous modules. However, the same report says there is about a 3% chance of an accident with no release, and a .4% chance of an accident "with release".
