This report is the final archival record of the EPM Division. On October 1, 1994, OREL A was transferred to Physics Division and on January 1, 1995, the Engineering Physics and Mathematics Division and the Computer Applications Division reorganized to form the Computer Science and Mathematics Division and the Computational Physics and Engineering Division. Earlier reports in this series are identified on the previous pages, along with the progress reports describing ORNL's research in the mathematical sciences prior to 1984 when those activities moved into the Engineering Physics and Mathematics Division. The primary mission of the Engineering Physics and Mathematics Division is to develop and apply in concert the principles, methods and data of the engineering, nuclear, mathematical, computational and cognitive sciences to complex research problems of national importance. Partnerships with industry and universities are sought to develop and transfer technology that will improve the nation's competitiveness. The Division's core competency R&D capabilities include: computer science, human engineering, informatics, mathematics, nuclear data measurement and evaluation, nuclear engineering, reactor physics and neutronics, and robotics. Division staff have been active participants during the reporting period in defining, planning, and implementing the Department of Energy's (DOE) mission and goals relating to our core competencies. In addition, considerable effort has been extended in laying the groundwork for transferring technology developed in our division to the industrial sector. As in previous reports, our research is described through abstracts of journal articles, technical reports, and presentations organized into sections following the five major operating units in the division: Mathematical Sciences, Intelligent Systems, Nuclear Data and Measurement Analysis, Nuclear Analysis and Shielding, and the Engineering Physics Information Centers. Each section begins with an introduction highlighting honors, awards, and significant research accomplishments in that unit during the reporting period. The report concludes with appendices on personnel activity including staff additions, staff departures, and guest/short-term appointments, scientific and professional activities of division staff, technical conferences organized and/or sponsored by our division, division seminars, publications of division staff in journals, proceedings, and technical reports, papers presented by division staff at scientific meetings, and seminars by division staff. The report concludes with the division's organization chart, as of October 1, 1994, prior to the reorganizations described above. TABLE OF CONTENTS PREFACE iii Section 1. MATHEMATICAL SCIENCES 1.0.

    1 Inexpensive Mini Thermonuclear Reactor By Alexander Bolonkin [email protected] New York, April 2012 2 Article Thermonuclear Reactor 1 26 13 Inexpensive Mini Thermonuclear Reactor By Alexander Bolonkin C&R Co., [email protected] Abstract This proposed design for a mini thermonuclear reactor uses a method based upon a series of important innovations. A cumulative explosion presses a capsule with nuclear fuel up to 100 thousands of atmospheres, the explosive electric generator heats the capsule/pellet up to 100 million degrees and a special capsule and a special cover which keeps these pressure and temperature in capsule up to 0.001 sec. which is sufficient for Lawson criteria for ignition of thermonuclear fuel. Major advantages of these reactors/bombs is its very low cost, dimension, weight and easy production, which does not require a complex industry. The mini thermonuclear bomb can be delivered as a shell by conventional gun (from 155 mm), small civil aircraft, boat or even by an individual. The same method may be used for thermonuclear engine for electric energy plants, ships, aircrafts, tracks and rockets. ----------------------------------------------------------------------- Key words: Thermonuclear mini bomb, thermonuclear reactor, nuclear energy, nuclear engine, nuclear space propulsion. Introduction It is common knowledge that thermonuclear bombs are extremely powerful but very expensive and difficult to produce as it requires a conventional nuclear bomb for ignition. In stark contrast, the Mini Thermonuclear Bomb is very inexpensive. Moreover, in contrast to conventional dangerous radioactive or neutron bombs which generates enormous power, the Mini Thermonuclear Bomb does not have gamma or neutron radiation which, in effect, makes it a ―clean‖ bomb having only the flash and shock wave of a conventional explosive but much more powerful (from 1 ton of TNT and more, for example 100 tons).

  • 1 Distant Nuclear Fusion 1. Introduction 2. ITER
    Distant Nuclear Fusion By John Benson January 2021 1. Introduction When we look up at night and view the stars, everything we see is shining because of distant nuclear fusion. — Carl Sagan, Cosmos (1980, p. 238) I have been posting papers to Energy Central since 2017, and weekly posts since 2018. During this time, I have occasionally come across a subject and considered writing a post on it. The reason I haven’t is because, even though it is an advanced technology for producing energy, it will not produce any usable electric power for decades. There are currently two experiments that are designed to reach “break-even” fusion within the next several years, but this means that the experiment will inject as much energy into the inner, or core process as comes out in the form of high energy neutrons. Forget any energy-conversion efficiencies outside of the core – no electric energy will come out of these initial facilities in spite of huge amounts going in. One of these two projects, the International Thermonuclear Experimental Reactor (ITER) is in Saint-Paul-lez-Durance, France. The other, the National Ignition Facility (NIF) is here in my home town of Livermore, California. ITER is scheduled to turn on in 2025, and reach full power by 2035. NEF has been running for over a decade. ITER cost $25 billion. The cost of NIF is a bit difficult to parse. The official cost is $3.5 billion, but there were several earlier experiments that led up to NIF, and NIF has been expanded and modified since it was commissioned in 2009.

    NRDC Comments on The National Ignition Facility (NIF) and the Issue of Nonproliferation (August 23, 1995 Draft Study) Natural Resources Defense Council, Inc. 1350 New York Avenue, NW, Suite 300 Washington, D.C. 20005 Tel (main): (202) 783-7800 Cochran (direct dial): (202) 624-9329 Fax: (202) 783-5917 INTERNET: [email protected] "The National Ignition Facility (NIF) and the Issue of Nonproliferation" draft study prepared by the U.S. Department of Energy, Office of Nonproliferation, August 23, 1995 [hereafter "Draft NIF Report"] is inadequate in its treatment of the nonproliferation issues raised by the proposed construction and operation of the NIF facility. Major deficiencies are identified below. 1. The NIF May Fail to Ignite. The Draft NIF Report is written as if there were no unresolved technical issues that could affect whether NIF meets its performance goals. For example, under 'Background," the report states that NIF "is expected to reach the goal of ICF capsule ignition." (p. 3; see also p. 10) However, there are still unresolved issues regarding whether time dependent asymmetries of the energy absorbed by the DT capsules, within the proposed gas-filled hohlraum targets, will be too large to obtain ignition with NIF. 2. The Draft NIF Report fails to explain fully the primary objectives of NIF and the Stockpile Stewardship Program. The "Background" section states that As part of a broader Science-Based Stockpile Stewardship program, a primary interest of the Department of Energy in NIF is to preserve the core intellectual and technical competencies of the U.S. in nuclear weapons scientists as directed by the President during a nuclear test ban regime and without new weapons development and production.

  • Chapter Four Making Light of the Light Elements
    Chapter Four Making Light of the Light Elements Although itself a significant technical obstacle to the H-bomb project, Los Alamos found computing as only one of several critical problems. Other problems arose, as well, and weapons scientists acknowledged them at various times. Von Neumann, Teller, Wheeler and others early on established computing as a technical problem that stood in the way of understanding the Super configuration’s feasibility. Nuclear materials were also a bottleneck to the hydrogen weapon program, yet Los Alamos’s scientists recognized this problem later than they had the computing obstacle. Tritium in particular, from the time Konopinski had suggested incorporating this isotope into the Super theory, was a latent obstacle to the H-bomb program. After the Soviet Union detonated its first atomic weapon in 1949 tritium scientists began to view tritium as a serious critical problem facing the American thermonuclear project. Although the Russian A-bomb test represented in the United States a political event outside of the AEC technological system -- this event nevertheless forced both scientists and policymakers to reconsider the AEC’s pace and the intensity of nuclear weapons research. Only then the Commission called its materials production facilities into question. After President Truman instructed the AEC to explore further the hydrogen weapon in 1950, and when Ulam and his colleague’s calculations began to 174 show the ignition problems facing the Super, the tritium problem became blatant. Consequently, the Committee for Weapon Development demonstrate with reasonable certainty that the 1945-1946 ENIAC calculations were wrong. In 1949 the AEC found itself unprepared to begin a program of large- scale tritium production in part because its predecessor, the MED, had not constructed any facilities specifically for this purpose.

  • Y-12 and the Hydrogen Bomb
    Y-12 and the Hydrogen Bomb A major increase in nuclear weapons work came to Y-12 directly after the first Soviet Union nuclear test on August 29, 1949. Y-12 was already the main source of machining and manufacture of the necessary nuclear parts for the weapons being stockpiled and for the tests being conducted. By the time the Soviet Union exploded its first test, the United States had already exploded six. The soviet test, learned by US intelligence to have been a replica of Fat Man, hastened the investigation into espionage. The summer of 1950 saw Julius and Ethel Rosenberg, Harry Gold and David Greenglass arrested as spies. Klaus Fuchs, the person who gave the plans for Fat Man to the soviets, was also arrested early in 1950 in Great Britain and sentenced to 14 years in prison. He served nine years. Discussion of the need for a thermonuclear weapon began anew in 1949 when Edward Teller returned to Los Alamos at about the same time as the Soviet Union’s first test. Teller had earlier argued for the more potentially powerful weapon, but Robert Oppenheimer had refused to depart from the agreed upon atomic bomb designs using uranium for Little Boy and plutonium for Fat Man. After the Soviet test, Teller immediately began to push for the greater yields of explosive energy possible with the fusion of hydrogen. Oppenheimer was among those who continued to oppose the development of the hydrogen bomb. An increase in the production of uranium and plutonium was approved leading to additional increased workload for Y-12.

  • North Korea's
    North Korea’s “Thermonuclear” Test: The Paradox of Small, developing Nuclear Forces Anthony H. Cordesman The reports on North Korea’s latest nuclear test are now more an exercise in uncertainty than a clear demonstration of North Korea’s actual nuclear capabilities. North Korea may or may not have been able to demonstrate its ability to use a fission weapon to produce some form of fusion or thermonuclear yield. It is still equally possible that it has simply lied, tried some form of fission-fusion design and failed, or has some uncertain degree of success in “boosting” a fission weapon and claimed this made it a thermonuclear weapon. It is also important to understand that North Korea’s success in developing any given nuclear weapon will interact with its missile design reliability, and capability. This, in turn, presents the paradox that small nuclear forces with limited effectiveness can push a given power – particularly one with extreme authoritarian leadership – into nuclear postures that present far more risks than the far larger and more capable nuclear forces of major powers. Thermonuclear Options: Single Stage In the worst case, going from its past fission to a real thermonuclear design, the difference could be dramatic. It is possible, however, that North Korea has tested a crude single stage nuclear weapon more to celebrate its erratic leader than achieve major military effects, and it might well be difficult to determine its success in doing so. There are obvious risks in any public discussion of nuclear weapons design, but there are highly public sources that do seem accurate enough to illustrate the issues involved.

  • The Physics of Nuclear Weapons
    The Physics of Nuclear Weapons While the technology behind nuclear weapons is of secondary importance to this seminar, some background is helpful when dealing with issues such as nuclear proliferation. For example, the following information will put North Korea’s uranium enrichment program in a less threatening context than has been portrayed in the mainstream media, while showing why Iran’s program is of greater concern. Those wanting more technical details on nuclear weapons can find them online, with Wikipedia’s article Wikipedia’s article being a good place to start. The atomic bombs used on Hiroshima and Nagasaki were fission weapons. The nuclei of atoms consist of protons and neutrons, with the number of protons determining the element (e.g., carbon has 6 protons, while uranium has 92) and the number of neutrons determining the isotope of that element. Different isotopes of the same element have the same chemical properties, but very different nuclear properties. In particular, some isotopes tend to break apart or fission into two lighter elements, with uranium (chemical symbol U) being of particular interest. All uranium atoms have 92 protons. U-238 is the most common isotope of uranium, making up 99.3% of naturally occurring uranium. The 238 refers to the atomic weight of the isotope, which equals the total number of protons plus neutrons in its nucleus. Thus U-238 has 238 – 92 = 146 neutrons. U-235 has 143 neutrons and makes up almost all the remaining 0.7% of naturally occurring uranium. (U-234 is very rare at 0.005%, and other, even rarer isotopes exist, some of which have only been produced in the laboratory.) U-235 is the valuable isotope from a nuclear weapons or nuclear power point of view because it can serve as the primary fuel for a weapon or power plant, while U-238 cannot.
