Joining issue with an ex-DRDO scientist that Pokhran-II was not a full success and India needs to go for a few more nuclear tests, Atomic Energy commission chief Anil Kakodkar on Wednesday said the country has strong simulation capability and that additional tests were not required.

"We have enough data. We have comprehensive simulation capability and therefore there is no need for any more tests," Kakodkar said, days after K Santhanam ignited a controversy that Pokhran-II was a fizzle and did not give the desired yield. "We are very confident about the simulation capability,"

Indian nuclear scientists had already validated and bench marked the validated tool of the three dimensional simulation for earth motion and displacement data collected following Pokhran II tests in 1998, he said.

"We used the data of Beneberry nuclear tests of US of December 18,1970 to validate our 3-D simulation for earth motion and displacement and this validated tool was used for bench marking," Kakodkar said.

There is no need for series of tests to validate the yield since the tool and also observations are available, he said adding that it was published in the international journal Nuclear Technology in 2006 four years after its communication from Bhabha Atomic Research Centre (BARC).

Scaling up of nuetronic calculation can always be done, he said adding that all the observations and calculations were done by scientists from BARC.
