Video relate to Operation Grapple Z series
On 22 August 1958, US President Dwight D. Eisenhower announced a one-year moratorium on nuclear testing, effective 31 October 1958, if the Soviet Union and the United Kingdom also agreed to suspend testing. Britain had already indicated that it would do so, and the Soviet Union agreed on 30 August.[127] This did not mean an immediate end to testing; on the contrary, all three rushed to perform as much testing as possible before the deadline.[128] The British scientists needed to gather as much data as possible to allow them to design production nuclear weapons. As the prospect of increased American cooperation grew after October 1957, they knew that the quality and quantity of what the Americans would share would depend on what they had to offer. A new British test series, known as Grapple Z, commenced on 22 August. It explored new technologies such as the use of external neutron initiators, which had first been tried out with Orange Herald. Core boosting using tritium gas and external boosting with layers of lithium deuteride permitted a smaller, lighter Tom for two-stage devices. It would be the biggest and most complex British test series (wiki)
