What DAE Says
- Combined yield of Pokhran-II tests was 57 kt: 12 kt for the fission device; 45 kt for the TN one
- International seismologists got yield wrong because of the geological nature of Pokhran-II site
- Claims Pokhran-II yield was 4.45 times Pokhran-I, so TN device worked
- Iyengar can’t be sure about his calculations because he doesn’t know the parameters of the device.
- The radiochemical test of the Pokhran-II site proves its yield measurements were as expected
- The ratio of Mn54 to Ce144 shows fusion took place in excess of fission.
What Iyengar Says
- If so sure, why doesn’t DAE make public the video recording of the ground motion during the test?
- If international seismologists got Pokhran-I readings right, they wouldn’t get Pokhran II wrong, since site geology was more or less the same
- Pokhran-I yielded 8 kt. So, total yield at 4.45 times works to 36 kt. Since DAE assigned 12 kt for fission device, leaves only 24 kt for TN one.
- Says only 10 per cent of LiD fusion material burnt. His formula was confirmed by S.K. Sikka, then head of the BARC design team.
- Says error margins in the radiochemical residual analysis too large
- Both fission & fusion neutrons produce Mn 54, DAE ratio no confirmation
