India nuclear test 'did not work'


A retired atomic scientist who was closely associated with India's 1998 nuclear tests has said they were not as successful as was claimed.

K Santhanam said one of the tests - on a hydrogen bomb - had not worked, and that India would have to carry out more tests for a credible nuclear deterrent.

His statement has been dismissed by the government and his former colleagues.

The Indian tests led to similar tests by Pakistan, raising fears of a nuclear conflict between the two countries.

Cover-up?

K Santhanam is a respected Indian atomic scientist who was project director of the 1998 nuclear tests.

He now says that one of the five tests that were carried out, in which a thermonuclear device or hydrogen bomb was detonated, did not perform as well as expected.

He also said that everyone associated with the tests immediately recognised that something had gone wrong.

If his statement is accurate it points to a massive cover-up by India and also confirms what many in the West suspected at the time - that the nuclear devices India tested were not as powerful as had been thought.

India's government has dismissed Mr Santhanam's claim, which has also been disputed by senior officials of the BJP-led government which carried out the tests.

The scientist says that India is coming under pressure to sign up to the Comprehensive Nuclear Test Ban Treaty, a move he says would be disastrous since he contends that the country does not yet have a credible nuclear deterrent.

Pokhran II not fully successful: Scientist


NEW DELHI: The 1998 Pokhran II nuclear tests might have been far from the success they have been claimed to be. The yield of the thermonuclear [table=200][/table]explosions was actually much below expectations and the tests were perhap more a fizzle rather than a big bang.

The controversy over the yield of the tests, previously questioned by foreign agencies, has been given a fresh lease of life with K Santhanam, senior scientist and DRDO representative at Pokhran II, admitting for the first time that the only thermonuclear device tested was a "fizzle". In nuclear parlance, a test is described as a fizzle when it fails to meet the desired yield.

Santhanam, who was director for 1998 test site preparations, told TOI on Monday that the yield for the thermonuclear test, or hydrogen bomb in popular usage, was much lower than what was claimed. Santhanam, who was DRDO's chief advisor, could well have opened up the debate on whether or not India should sign CTBT as claims that India has all the data required and can manage with simulations is bound to be called into question.

``Based upon the seismic measurements and expert opinion from world over, it is clear that the yield in the thermonuclear device test was much lower than what was claimed. I think it is well documented and that is why I assert that India should not rush into signing the CTBT,'' Santhanam told TOI on Wednesday.

He emphasised the need for India to conduct more tests to improve its nuclear weapon programme.

The test was said to have yielded 45 kilotons (KT) but was challenged by western experts who said it was not more than 20 KT.

The exact yield of the thermonuclear explosion is important as during the heated debate on the India-

US nuclear deal, it was strenuously argued by the government's top scientists that no more tests were required for the weapons programme. It was said the disincentives the nuclear deal imposed on testing would not really matter as further tests were not required.

According to security expert Bharat Karnad, Santhanam's admission is remarkable because this is the first time a nuclear scientist and one closely associated with the 1998 tests has disavowed the government line. ``He is not just saying that India should not sign the CTBT, which I believe is completely against India's interests, but also that the 1998 thermonuclear device test was inadequate.

His saying this means that the government has to do something. Either you don't have a thermonuclear deterrent or prove that you have it, if you claim to have it,'' said Karnad.

Sources said that Santhanam had admitted that the test was a fizzle during a discussion on CTBT organised by IDSA. Karnad also participated in the seminar. He told TOI that no country has succeeded in achieving targets with only its first test of a thermonuclear device.

``Two things are clear; that India should not sign CTBT and that it needs more thermonuclear device tests,'' said Santhanam.

The yield of the thermonuclear device test in 1998 has led to much debate and while western experts have stated that it was not as claimed, BARC has maintained that it stands by its assessment. Indian scientists had claimed after the test that the thermonuclear device gave a total yield of 45 KT, 15 KT from the fission trigger and 30 KT from the fusion process and that the theoretical yield of the device (200 KT) was reduced to 45 KT in order to minimise seismic damage to villages near the test range.
British experts, however, later challenged the claims saying that the actual combined yield for the fission device and thermonuclear bomb was not more than 20 KT.

Key Pokharan scientist R Chidambaram had described these reports as incorrect. He has also argued that computer simulations would be enough in future design.
兄弟,下次译了再发吧,俺的眼花了.拜托
大体说核试中的氢弹失败了。所以认为不应该急于签署核禁试条约,必须进行更多的测试,以改善它的核武器
哦?
头回听说!
那三哥现在装备的都是威慑弹??
MS氢弹失败了吧!
晕 LS的几位仁兄怎么看的?
不是实验失败   是没有达到预期的威力而已
这个东东有没有是质变    至于当量是小男孩还是沙皇弹并不重要
