Point Kinetic Model of the Early Phase of a Spherically Symmetric Nuclear Explosion
Point kinetic model of the early phase of a spherically symmetric nuclear explosion Andreas Walter Aste Department of Physics, University of Basel, 4056 Basel, Switzerland June 6, 2016 Abstract A concise point kinetic model of the explosion of a prompt supercritical sphere driven by a nu- clear fission chain reaction is presented. The findings are in good agreement with the data available for Trinity, the first detonation of a nuclear weapon conducted by the United States Army as part of the Manhattan project. Results are presented for an implosion device containing pure plutonium- 239, although the model can be easily applied to, e.g., uranium-235. The fizzle probability and cor- responding yield of a fission bomb containing plutonium recovered from reactor fuel and therefore containing significant amounts of spontaneously fissioning plutonium-240 which can induce a pre- detonation of the device is illustrated by adding a corresponding source term in the presented model. Related questions whether a bomb could be made by developing countries or terrorist organizations can be tackled this way. Although the information needed to answer such questions is in the public domain, it is difficult to extract a consistent picture of the subject for members of organizations who are concerned about the proliferation of nuclear explosives. Physics and Astronomy Classification Scheme (2010). 28.20.-v Neutron physics; 25.85.Ec Neutron-induced fission; 28.70.+y Nuclear explosions. 1 Introduction Despite the terrifying fact that numerous operational fission or even thermonuclear bombs exist on our planet, there is a great interest in the basic principles and physics underlying the concept of nuclear weapons. -
Review of Generation IV Nuclear Energy Systems REPORT SUMMARY
REPORT Review of Generation IV Nuclear Energy Systems REPORT SUMMARY According to many energy foresight studies carried out in the late 1990s, a shortage of uranium can be expected during the 21st century. This spurred the United States Department of Energy (DOE) to set up the Generation IV International Forum (GIF) in 2000, for the purpose of coordinating research and development work aimed at deploying Generation IV nuclear energy systems (reactors and the related fuel cycle facilities), by the second half of this century. Member countries, including France, proposed more than a hundred such systems, of which GIF selected six, considered the most promising in light of various criteria based on the following objectives: continuation of the progress made by Generation III water reactors in terms of competitiveness and safety; more effective use of uranium resources; less radioactive waste, especially high-level, long-lived waste; greater protection against malicious acts and the diversion or theft of nuclear materials. The six systems selected by GIF are: Sodium-cooled Fast Reactors (SFR); Very High Temperature Reactors (VHTR); Gas-cooled Fast Reactors (GFR); Lead-cooled or Lead-Bismuth Eutectic (LBE) cooled Fast Reactors (LFR); Molten Salt Reactors (MSR); SuperCritical Water Reactors (SCWR). GIF selected several fast neutron spectrum systems as they facilitate the transmutation of fertile material into fissile material and, in some configurations, are capable of breeding fissile material. SFR, LFR, GFR and MSR systems are in this category. These characteristics could lead to improved use of energy resources. Furthermore, high-temperature coolants can be used to improve the energy efficiency of nuclear power plants as well as nuclear facilities, such as the VHTR, that could be used to generate process heat for industry. -

Most of the requested changes to the Technical Specifications are considered to be minor; however, because of the number of changes and reorganization, the changes are not marked with the usual vertical line in the margin. Nevertheless, the following paragraphs provide a summary of the more significant requested changes where all the section and paragraph designations refer to the new reformatted and reorganized Technical Specifications generated as part of Chapter 14 of the FSAR to support relicensing. First, in Section 3.2.1, "Reactor Control System," Paragraph (3), a clarification is added to allow the reactor to be operated without the autocontroller function available provided the autocontroller is not needed and not used for the operation. This change is justified in that there are many times, especially when operating at low power levels or for relatively short periods of time for training, irradiations or other operations, when the autocontroller function is neither needed nor used. Except for lengthy runs at constant power, the autocontroller function is primarily a convenience versus a necessary safety-related feature. -

The work presented details quantified proliferation resistance metrics of a pressurized water reactor (PWR), a PWR utilizing thorium as a fertile component of the nuclear fuel (Radkowsky Thorium Reactor-RTR) and a high temperature, gas cooled, reactor with a pebble bed core (PBMR). This probabilistic method permits integration of all aspects of fissile material proliferation in formulating an overall estimate of relative proliferation risk. -
