(Signature) ……………………………………………………………………………… 1 Abstract There was no special governmental partnership between Britain and America during the Second World War in atomic affairs. A recalibration is required that updates and amends the existing historiography in this respect. The wartime atomic relations of those countries were cooperative at the level of science and resources, but rarely that of the state. As soon as it became apparent that fission weaponry would be the main basis of future military power, America decided to gain exclusive control over the weapon. Britain could not replicate American resources and no assistance was offered to it by its conventional ally. America then created its own, closed, nuclear system and well before the 1946 Atomic Energy Act, the event which is typically seen by historians as the explanation of the fracturing of wartime atomic relations. Immediately after 1945 there was insufficient systemic force to create change in the consistent American policy of atomic monopoly. As fusion bombs introduced a new magnitude of risk, and as the nuclear world expanded and deepened, the systemic pressures grew. -
The Threat of Nuclear Proliferation: Perception and Reality Jacques E
ROUNDTABLE: NONPROLIFERATION IN THE 21ST CENTURY The Threat of Nuclear Proliferation: Perception and Reality Jacques E. C. Hymans* uclear weapons proliferation is at the top of the news these days. Most recent reports have focused on the nuclear efforts of Iran and North N Korea, but they also typically warn that those two acute diplomatic headaches may merely be the harbingers of a much darker future. Indeed, foreign policy sages often claim that what worries them most is not the small arsenals that Tehran and Pyongyang could build for themselves, but rather the potential that their reckless behavior could catalyze a process of runaway nuclear proliferation, international disorder, and, ultimately, nuclear war. The United States is right to be vigilant against the threat of nuclear prolifer- ation. But such vigilance can all too easily lend itself to exaggeration and overreac- tion, as the invasion of Iraq painfully demonstrates. In this essay, I critique two intellectual assumptions that have contributed mightily to Washington’s puffed-up perceptions of the proliferation threat. I then spell out the policy impli- cations of a more appropriate analysis of that threat. The first standard assumption undergirding the anticipation of rampant pro- liferation is that states that abstain from nuclear weapons are resisting the dictates of their narrow self-interest—and that while this may be a laudable policy, it is also an unsustainable one. According to this line of thinking, sooner or later some external shock, such as an Iranian dash for the bomb, can be expected to jolt many states out of their nuclear self-restraint. -

Science, Scientific Intellectuals and British Culture in the Early Atomic Age, 1945-1956: a Case Study of George Orwell, Jacob Bronowski, J.G
Science, Scientific Intellectuals and British Culture in The Early Atomic Age, 1945-1956: A Case Study of George Orwell, Jacob Bronowski, J.G. Crowther and P.M.S. Blackett Ralph John Desmarais A Dissertation Submitted In Fulfilment Of The Requirements For The Degree Of Doctor Of Philosophy Imperial College London Centre For The History Of Science, Technology And Medicine 2 Abstract This dissertation proposes a revised understanding of the place of science in British literary and political culture during the early atomic era. It builds on recent scholarship that discards the cultural pessimism and alleged ‘two-cultures’ dichotomy which underlay earlier histories. Countering influential narratives centred on a beleaguered radical scientific Left in decline, this account instead recovers an early postwar Britain whose intellectual milieu was politically heterogeneous and culturally vibrant. It argues for different and unrecognised currents of science and society that informed the debates of the atomic age, most of which remain unknown to historians. Following a contextual overview of British scientific intellectuals active in mid-century, this dissertation then considers four individuals and episodes in greater detail. The first shows how science and scientific intellectuals were intimately bound up with George Orwell’s Nineteen Eighty Four (1949). Contrary to interpretations portraying Orwell as hostile to science, Orwell in fact came to side with the views of the scientific rig h t through his active wartime interest in scientists’ doctrinal disputes; this interest, in turn, contributed to his depiction of Ingsoc, the novel’s central fictional ideology. Jacob Bronowski’s remarkable transition from pre-war academic mathematician and Modernist poet to a leading postwar BBC media don is then traced. -
Britain's Pacific H-Bomb Tests
Introduction From the beginning of the nuclear age, the United States, Britain and France sought distant locations to conduct their Cold War programs of nuclear weapons testing. For 50 years between 1946 and 1996, the islands of the central and south Pacific and the deserts of Australia were used as a ‘nuclear playground’ to conduct more than 315 atmospheric and underground nuclear tests, at 10 different sites.1 These desert and ocean sites were chosen because they seemed to be vast, empty spaces. But they weren’t empty. The Western nuclear powers showed little concern for the health and wellbeing of nearby indigenous communities and the civilian and military personnel who staffed the test sites. In the late 1950s, nearly 14,000 British military personnel and scientific staff travelled to the British Gilbert and Ellice Islands Colony (GEIC) in the central Pacific to support the United Kingdom’s hydrogen bomb testing program. In this military deployment, codenamed Operation Grapple, the British personnel were joined by hundreds of NZ sailors, Gilbertese labourers and Fijian troops.2 Many witnessed the nine atmospheric nuclear tests conducted at Malden Island and Christmas (Kiritimati) Island between May 1957 and September 1958. Today, these islands are part of the independent nation of Kiribati.3 1 Stewart Firth: Nuclear Playground (Allen and Unwin, Sydney, 1987). 2 Between May 1956 and the end of testing in September 1958, 3,908 Royal Navy (RN) sailors, 4,032 British army soldiers and 5,490 Royal Air Force (RAF) aircrew were deployed to Christmas Island, together with 520 scientific and technical staff from the Atomic Weapons Research Establishment (AWRE)—a total of 13,980 personnel. -

Ernest Marsden's Nuclear New Zealand
Journal & Proceedings of the Royal Society of New South Wales, Vol. 139, p. 23–38, 2006 ISSN 0035-9173/06/010023–16 $4.00/1 Ernest Marsden’s Nuclear New Zealand: from Nuclear Reactors to Nuclear Disarmament rebecca priestley Abstract: Ernest Marsden was secretary of New Zealand’s Department of Scientific and Industrial Research from 1926 to 1947 and the Department’s scientific adviser in London from 1947 to 1954. Inspired by his early career in nuclear physics, Marsden had a post-war vision for a nuclear New Zealand, where scientists would create radioisotopes and conduct research on a local nuclear reactor, and industry would provide heavy water and uranium for use in the British nuclear energy and weapons programmes, with all these ventures powered by energy from nuclear power stations. During his retirement, however, Marsden conducted research into environmental radioactivity and the impact of radioactive bomb fallout and began to oppose the continued development and testing of nuclear weapons. It is ironic, given his early enthusiasm for all aspects of nuclear development, that through his later work and influence Marsden may have actually contributed to what we now call a ‘nuclear-free’ New Zealand. Keywords: Ernest Marsden, heavy water, nuclear, New Zealand INTRODUCTION to nuclear weapons development – which he was happy to support in the 1940s and 1950s In the 1990s, Ross Galbreath established Ernest – changed in his later years. By necessity this Marsden as having been the driving force be- article includes some material already covered hind the involvement of New Zealand scientists by Galbreath and Crawford but it also covers on the Manhattan and Montreal projects, the new ground. -
Lorna Arnold Laudatio
27 XI 09 LORNA ARNOLD LAUDATIO Mr Vice Chancellor, Apart from the personal pride and pleasure I take in presenting this candidate to you for an Honorary Doctorate, there are, I suggest three reasons why the University of Reading can share my personal excitement in our association with Lorna Arnold. Through her, we acknowledge the British government’s tradition of opening the doors to scholarship and research in even the most secret areas – here, nuclear weapons. This openness is so vital, not only to our work in Politics & International Relations but, more importantly, for democratic accountability. We recognise and celebrate conscientious and fair scholarship. This is particularly hard to achieve, I would suggest, in this sensitive area of research which Lorna Arnold has matched and even set highest standards of accuracy with fairness of analysis. In this, she serves as a model to all scholars. Through her, we honour the pioneering work of the British Atomic Energy Authority, particularly as carried out in Reading’s small suburb of Aldermaston; - and I am pleased to welcome our guests from the Authority who have joined us here today - Ms Mary Hills - Mr Andrew Hills, - and Mr Michael McTaggart. Turning to the honorary graduand herself: Lorna Rainbow, born in the First World War, was set to become a teacher of English literature when the Second World War came along and rocked her life. She was encouraged to join the War Office, as a civilian official, soon involved in the work of the Special Operations Executive. In 1944 she joined the Foreign Office, where she was probably the first female British diplomat.
