General-purpose heat source development: Safety Verification Test Program. Titanium bullet/fragment test series
The radioisotope thermoelectric generator (RTG) that will provide power for the Galileo and Ulysses space missions contains 18 General-Purpose Heat Source (GPHS) modules. Each module contains four /sup 238/PuO/sub 2/-fueled clads and generates 250 W(t). Because the possibility of launch-pad or postlaunch explosion exists and because any explosion would generate a field of high-energy fragments, the fueled clads within each GPHS module must be able to survive fragment impact. In this test series we investigated the response of bare, simulant-fueled (UO/sub 2/) clads to the impact of high-energy titanium alloy fragments. We determined that 425m/s is the threshold impact velocity of a 3.25-g titanium bullet that will cause direct mechanical failure of a bare fueled clad. 40 figs.
