The Making of an Atomic Bomb
(Image: Courtesy of United States Government, public domain.) INTRODUCTORY ESSAY "DESTROYER OF WORLDS": THE MAKING OF AN ATOMIC BOMB At 5:29 a.m. (MST), the world’s first atomic bomb detonated in the New Mexican desert, releasing a level of destructive power unknown in the existence of humanity. Emitting as much energy as 21,000 tons of TNT and creating a fireball that measured roughly 2,000 feet in diameter, the first successful test of an atomic bomb, known as the Trinity Test, forever changed the history of the world. The road to Trinity may have begun before the start of World War II, but the war brought the creation of atomic weaponry to fruition. The harnessing of atomic energy may have come as a result of World War II, but it also helped bring the conflict to an end. How did humanity come to construct and wield such a devastating weapon? 1 | THE MANHATTAN PROJECT Models of Fat Man and Little Boy on display at the Bradbury Science Museum.

Harry Truman, the Atomic Bomb and the Apocalyptic Narrative
Volume 5 | Issue 7 | Article ID 2479 | Jul 12, 2007 The Asia-Pacific Journal | Japan Focus The Decision to Risk the Future: Harry Truman, the Atomic Bomb and the Apocalyptic Narrative Peter J. Kuznick The Decision to Risk the Future: Harry stressed that the future of mankind would be Truman, the Atomic Bomb and theshaped by how such bombs were used and Apocalyptic Narrative subsequently controlled or shared.[3] Truman recalled Stimson “gravely” expressing his Peter J. Kuznick uncertainty about whether the U.S. should ever use the bomb, “because he was afraid it was so I powerful that it could end up destroying the whole world.” Truman admitted that, listening In his personal narrative Atomic Quest, Nobel to Stimson and Groves and reading Groves’s Prize-winning physicist Arthur Holly Compton, accompanying memo, he “felt the same who directed atomic research at the University fear.”[4] of Chicago’s Metallurgical Laboratory during the Second World War, tells of receiving an urgent visit from J. Robert Oppenheimer while vacationing in Michigan during the summer of 1942. Oppenheimer and the brain trust he assembled had just calculated the possibility that an atomic explosion could ignite all the hydrogen in the oceans or the nitrogen in the atmosphere. If such a possibility existed, Compton concluded, “these bombs must never be made.” As Compton said, “Better to accept the slavery of the Nazis than to run a chance of drawing the final curtain on mankind.”[1] Certainly, any reasonable human being could be expected to respond similarly. Three years later, with Hitler dead and the Nazis defeated, President Harry Truman faced Truman and Byrnes en route to Potsdam, July a comparably weighty decision. -

This policy transition was controversial, causing friction with U.S. allies, with the nuclear power industry, and with Congress. Early in his presidential campaign, Carter criticized the excessive federal financial commitment to developing plutonium-based reactors and adopted the view that the weapons proliferation risks of plutonium economy technologies were serious and needed to be addressed. -
Atomic Physics & Quantum Effects
KEY CONCEPTS ATOMIC PHYSICS & QUANTUM EFFECTS 1. PHOTONS & THE PHOTOELECTRIC EFFECT Max Planck explained blackbody radiation with his quantum hypothesis, which states that the energy of a thermal oscillator, Eosc, is not continuous, but instead is a discrete quantity given by the equation: Eosc = nhf n = 1, 2, 3,... where f is the frequency and h is a constant now known as Planck’s constant. Albert Einstein extended the idea by adding that all emitted radiation is quantized. He suggested that light is composed of discrete quanta, rather than of waves. According to his theory, each particle of light, known as a photon, has an energy E given by: E = hf Einstein’s theory helped him explain a phenomenon known as the photoelectric effect, in which a photon of light strikes a photosensitive material and causes an electron to be ejected from the material. A photocell constructed from photosensitive material can produce an electrical current when light shines on it. The kinetic energy, K, of a photoelectron displaced by a photon of energy, hf, is given by: K = hf - φ where the work function, φ, is the minimum energy needed to free the electron from the photosensitive material. No photoemission occurs if the frequency of the incident light falls below a certain cutoff frequency – or threshold frequency – given by: φ f0 = h Einstein's theory explained several aspects of the photoelectric effect that could not be explained by classical theory: • The kinetic energy of photoelectrons is dependent on the light’s frequency. • No photoemission occurs for light below a certain threshold frequency. -

Study of Advanced Lwr Cores for Effective Use of Plutonium and Mox Physics Experiments
STUDY OF ADVANCED LWR CORES FOR EFFECTIVE USE OF PLUTONIUM AND MOX PHYSICS EXPERIMENTS T. YAMAMOTO, H. MATSU-URA*, M. UEJI, H. OTA XA9953266 Nuclear Power Engineering Corporation, Toranomon, Minato-ku, Tokyo T. KANAGAWA Mitsubishi Heavy Industries, Ltd, Nishi-ku, Yokohama K. SAKURADA Toshiba Corporation, Isogo-ku, Yokohama H.MARUYAMA Hitachi, Ltd, Hitachi-shi Japan Abstract Advanced technologies of full MOX cores have been studied to obtain higher Pu consumption based on the advanced light water reactors (APWRs and ABWRs). For this aim, basic core designs of high moderation lattice (H/HM ~5) have been studied with reduced fuel diameters in fuel assemblies for APWRs and those of high moderation lattice (H/HM ~6) with addition of extra water rods in fuel assemblies for ABWRs. The analysis of equilibrium cores shows that nuclear and thermal hydraulic parameters satisfy the design criteria and the Pu consumption rate increases about 20 %. An experimental program has been carried out to obtain the core parameters of high moderation MOX cores in the EOLE critical facility at the Cadarache Centre as a joint study of NUPEC, CEA and CEA's industrial partners. The experiments include a uranium homogeneous core, two MOX homogeneous cores of different moderation and a PWR assembly mock up core of MOX fuel with high moderation. The program was started from 1996 and will be completed in 2000. 1. INTRODUCTION In Japan, the MOX fuel demonstration programs have been performed successfully and reload size use of MOX fuel has been prepared. The recycling of plutonium in light water reactors is expected to continue in several decades. -

More than one-third of all professional and technical workers are employed by government, particularlyinadministrative positions, and exert an increasing influence on public policy. But, with the exception of city managers, many of these employees regard themselves as members of the disciplines in which they weretrained rather than primarily as public administrators. The field of public administrationhas not influenced public policy as much as other fields have, possibly because: it is not a specialized profession; practitioners do not agree on what its core knowledge,skills and orientation should be; and there is little incentive for students to pursue studies in the field since most administrative positions are held by otherspecialists. Althou9h more attention in colleges is now being paid toadministrative and management fields, courses are usually based onorganizational theories of private business models, with little emphasis on the unique problems of government administration.Professional schools suffer from a general bias against teaching the kinds of subjects thatmight be useful in government jobs. -
Luis Alvarez: the Ideas Man
CERN Courier March 2012 Commemoration Luis Alvarez: the ideas man The years from the early 1950s to the late 1980s came alive again during a symposium to commemorate the birth of one of the great scientists and inventors of the 20th century. Luis Alvarez – one of the greatest experimental physicists of the 20th century – combined the interests of a scientist, an inventor, a detective and an explorer. He left his mark on areas that ranged from radar through to cosmic rays, nuclear physics, particle accel- erators, detectors and large-scale data analysis, as well as particles and astrophysics. On 19 November, some 200 people gathered at Berkeley to commemorate the 100th anniversary of his birth. Alumni of the Alvarez group – among them physicists, engineers, programmers and bubble-chamber film scanners – were joined by his collaborators, family, present-day students and admirers, as well as scientists whose professional lineage traces back to him. Hosted by the Lawrence Berkeley National Laboratory (LBNL) and the University of California at Berkeley, the symposium reviewed his long career and lasting legacy. A recurring theme of the symposium was, as one speaker put it, a “Shakespeare-type dilemma”: how could one person have accom- plished all of that in one lifetime? Beyond his own initiatives, Alvarez created a culture around him that inspired others to, as George Smoot put it, “think big,” as well as to “think broadly and then deep” and to take risks. Combined with Alvarez’s strong scientific standards and great care in execut- ing them, these principles led directly to the awarding of two Nobel Luis Alvarez celebrating the announcement of his 1968 Nobel prizes in physics to scientists at Berkeley – George Smoot in 2006 prize. -
