Three such tests Testing had been conducted Action since 1982 , but had failed to provide Supply a solution .

although `` cardiff '' was suspected Suspicion , later scientific tests Testing on the wreckage proved Coming_to_believe inconclusive .

India had conducted Action its first successful test in 1974 ; Pakistan , which had been developing Cause_to_make_progress its nuclear capability in secret since around the same time , conducted Action its first known tests in 1998 , just two weeks after a second series of tests by India .

Because the yields for many tests at `` Operation Castle '' in 1954 were dramatically higher than predictions , `` Redwing '' was conducted Action using Using an `` energy budget '' : There were limits Limiting to the total amount of energy released , and the amount of fission yield was also strictly controlled Control .

Operation Grapple was the name of four series of British nuclear weapons tests Testing of early atomic bombs and hydrogen bombs Attack carried out Action in 1957 and 1958 at Malden Island and Kiritimati ( Christmas Island ) in the Pacific Ocean as part of the British hydrogen bomb programme .

The first test Research series consisted of three tests Testing in May and June 1957 .

A final series of four tests Testing in August and September 1958 , known as Grapple Z , tested Testing techniques for boosting Cause_to_make_progress and making Manufacturing bombs immune to predetonation caused Causation by nearby nuclear explosions .

Two of these tests were detonations from balloons ; another was a blind radar test Research drop .

Castle Bravo was the first in a series of high-yield thermonuclear weapon design tests conducted Action by the United States at Bikini Atoll , Marshall Islands , as part of `` Operation Castle '' .

For a time , geopolitical events Confronting_problem and natural disasters Catastrophe had strong short-term effects Influence on oil prices Cost , such as North Korean missile tests Testing , the 2006 conflict Hostile_encounter between Israel and Lebanon , worries over Iranian nuclear plans Arranging in 2006 , Hurricane Catastrophe Katrina Catastrophe , and various other factors .

the unk tests were a series of five nuclear bomb test Testing explosions Use_firearm conducted by india at the indian army 's pokhran test Research range in may 1998 .

The tests achieved Achieve their main objective of giving Giving India the capability to build Building fission and thermonuclear weapons with yields up to 200 Kilotons .

the then chairman of the indian atomic energy commission described Statement each one of the explosions of `` unk '' to be `` equivalent to several tests carried out Action by other nuclear weapon states over decades '' .

The tests were initiated Process_start on 11 May 1998 , under the assigned code name `` Operation Shakti '' , with the detonation of one fusion and two fission bombs .

The tests resulted in Causation a variety of sanctions against India by a number of major states , including Japan and the United States .

Many names have been assigned Choosing to these tests ; originally these were collectively called Name_conferral `` Operation Shakti–98 '' , and the five nuclear bombs were designated Choosing `` Shakti-I '' through to `` Shakti-V '' .

These tests Testing by Pakistan and India resulted in Causation United Nations Security Council Resolution 1172 and economic sanctions Preventing_or_letting on both states by a number of major powers Influence , particularly the United States and Japan .

Its timing Deciding was a direct response Response to India 's second nuclear tests Testing , on 11 and 13 May 1998 .

Chagai-I is the code name of five simultaneous underground nuclear tests conducted Action by Pakistan at 15:15 hrs PST on 28 May 1998 .

The tests were performed Hold at Ras Koh Hills in the Chagai District of Balochistan Province .

They were the first nuclear weapon tests Testing since Trinity in July 1945 , and the first detonations of nuclear devices since the atomic bombing Attack of Nagasaki on August 9 , 1945 .

Operation Crossroads was a pair of nuclear weapon tests Testing conducted Action by the United States at Bikini Atoll in mid-1946 .

The purpose of the tests was to investigate Research the effect of nuclear weapons on warships .

The Crossroads tests were the first of many nuclear tests held Hold in the Marshall Islands , and the first to be publicly announced Expressing_publicly beforehand and observed Perception_active by an invited audience , including a large press corps .

In the 1950s , a series of large thermonuclear tests rendered Causation Bikini unfit for subsistence farming and fishing because of radioactive contamination .

Planners attempted to protect Defending participants in the Operation Crossroads tests against radiation sickness , but one study showed Protest that the life expectancy of participants was reduced Cause_change_of_position_on_a_scale by an average of three months .

Australia regained Getting the Mandela Challenge Plate after winning Getting their two home tests Testing against South Africa .

in the fifth and final test Testing england beat Competition australia for the first time since 1938 and ended Process_end their unbeaten run of 14 tests against england , 26 tests against all teams and 96 games in all cricket since the second world war .

The Thor missile was also used Using to lift Body_movement warheads into near-space to conduct Action high-altitude nuclear explosion tests Testing ; these shots Use_firearm were collectively called Name_conferral Operation Fishbowl .

Nikita Khrushchev announced Expressing_publicly the end Process_end of a three-year moratorium on nuclear testing Testing on August 30 , 1961 , and Soviet tests recommenced Process_start on September 1 , initiating Process_start a series of tests Testing that included Cause_to_be_included the detonation of Tsar Bomba .

Within 24 hours of the accident Catastrophe , the United States Department of Commerce ( the governing Action authority of the CAA ) ordered Request that all Lockheed Super Electras be immediately grounded Motion and that tests be performed Action to confirm that the figures obtained Getting in the aircraft 's original vibration tests were accurate .

Operation Sandstone was a series of nuclear weapon tests in 1948 .

It was the third series of American tests , following Trinity in 1945 and Crossroads in 1946 , and preceding Ranger .

Like the Crossroads tests , the Sandstone tests were carried out Action at the Pacific Proving Grounds , although at Enewetak Atoll rather than Bikini Atoll .

The purpose Aiming of the Sandstone tests was also different : they were primarily tests of new bomb designs rather than of the effects of nuclear weapons .

three tests were carried out Action in april and may 1948 by joint task force 7 , with a work force of unk personnel , of whom unk were military .

The successful testing of the new cores in the `` Operation Sandstone '' tests rendered Causation every component of the old weapons obsolete .

These early fracturing tests were later superseded by hydraulic fracturing technologies .

British nuclear tests Testing at Maralinga occurred Presence between 1956 and 1963 at the Maralinga site , part of the Woomera Prohibited Area in South Australia and about 800 kilometres north-west of Adelaide .

A total of seven nuclear tests Testing were performed Action , with approximate yields Creating ranging from .

the mcclelland royal commission Research , an examination Scrutiny of the effects Influence of the tests Testing , delivered Sending its report Reporting in 1985 , and found Know that significant radiation hazards still existed Presence at many of the maralinga test Research areas .

The Maralinga tests Testing were subject to extreme secrecy , but by the late 1970s there was a marked change Change in how the Australian media covered Hiding_objects the British nuclear tests Testing .
