It was realized there were nuclear poisons - fission products that easily absorb neutrons. The fix was very simple once the issue was known: simply increase the rate of fusion and "burn off" the nuclear poisons. One relatively common fission product is 92235U+01n4098Zr+52135Te+301n (a) 4098Zr goes through two beta minus decays before becoming stable, What is the final daughter nucleus
