Two Stage TN test claimed by R. ChidambaramDr. Chidambaram wrote that the thermonuclear device tested was “a two-stage device of advanced design, which had a fusion-boosted fission trigger as the first stage and a fusion secondary stage which was compressed by radiation implosion and ignited.”
PS: Title of original article changed to make the point.
OK I have to accept that. As per a Google search this was stated in 2000 That was his only reference to a "radiation implosion." That expression was used once and I must admit that it must mean something. The words "radiation implosion" were never used again.
I have an archive of many of the news reports of that time. In other articles he wrote:
In an article written for SAAG in 2003 Chidambaram wrote
The two-stage thermonuclear device, with a fusion-boosted fission trigger as the first stage and with the features needed for integration with delivery vehicles, was tested at the controlled yield of 45 kt and had the purpose of developing nuclear weapons with yields upto around 200 kilotons. .
In a separate press release he wrote the same thing.
Strangely he never claimed a megaton in either report. In the first one from 2000 where radiation implosion was mentioned he writes:

Thermonuclear weapons of various yields upto around 200 kt can be confidently designed on the basis of this test.
Testing a two-stage thermonuclear device with a fusion-boosted fission trigger as the first stage and with the features needed for integration with delivery vehicles at the controlled yield of 45 kt with the purpose of developing nuclear weapon systems with yields upto around 200 kilotons.
the carefully-planned series of tests carried out in May 1998 gave us the capability to design confidently and build nuclear weapons from low yields upto around 200 kilotons.
Why was the scalable yield never claimed to be over 200 kt if a Teller Ulam device was tested - which is scalable to any yield over 1 megaton. The USs first test was 10 megatons IIRC. There is something missing from the information we have about the actual design that was tested.
I accept that a Teller Ulam device cannot be perfected in one test - but if I know this why would one assume that scientists would not know this. They would likely have tested something that would give the most information on what will work reliably rather than a design that leaves them high and dry requiring 10 or 15 more tests. I am certain that Vajpayee had warned the team that opportunities to test would not arise again and that they would have to make the best of this opportunity. I find it difficult to believe that they would have gone and tested something that is predictably uncertain - and a design that no country has perfected in just one test.
