Tritium is produced in a nuclear reactor in ternary fission, in which one 3H nucleus is produced in every 10^4 fissions. What is the tritium activity in a reactor core that had been operating at a mean power level of 3000 MW(t) for 2 years? The answer has to be in Ci or Bq. The answer is: 2.9 x 10^4 Ci or 1.1 x 10^15 Bq. Please show me the work.
