The properties of single helicity and multiple Ohmic states in reversed-field pinches (RFP’s) are investigated by a combination analytic numerical methods. results show that toroidal field reversal can be provided helical equilibrium driven loop voltage, symmetry is related to stellarator transform. Nevertheless, constant λ≡j∥/B state cannot sustained because λ must reverse at the surface. This thought as saturated an unstable tearing mode. For force-free plasma, maintained relatively small...
AbstractWe must anticipate that the day is approaching when details of nuclear weapons design and fabrication will become common knowledge. On we be particularly certain all special materials (SNM) are adequately accounted for protected have a clear understanding utility to potential adversaries. To this end, paper examines attractiveness mixtures containing SNM alternate associated with plutonium-uranium reduction extraction (Purex), uranium (UREX), coextraction (COEX), thorium (THOREX),...
AbstractThe ARIES research program is a multi-institutional effort to develop several visions of tokamak reactors with enhanced economic, safety, and environmental features. Three are currently planned for the program. The ARIES-I design DT-burning reactor based on "modest" extrapolations from present physics database relies either existing technology or which trends already in place, often programs outside fusion; ARIES-II will employ potential advances physics; ARIES-III conceptual D-3He...

The Advanced Reactor Innovation and Evaluation Study (ARIES) is a community effort to develop several visions of the tokamak as fusion power reactor. aims are determine its potential economics, safety, environmental features identify physics technology areas with highest leverage for achieving best authors focus on ARIES-1 design. Parametric systems studies show that optimum first stability has relatively low plasma current ( approximately 12 MA), high aspect ratio 4-6), magnetic field 24 T...
AbstractNFCSim is an event-driven, time-dependent simulation code modeling the flow of materials through nuclear fuel cycle. NFCSim tracks mass at level discrete reactor charges/discharges and logs history material as it progresses a detailed series processes facilities, generating life-cycle balances for any number reactors. ideal tool analysis - economics, sustainability, or proliferation resistance nonequilibrium, interacting, evolving fleets. The software couples with criticality burnup...
Lessons from the four-year ARIES (Advanced Reactor Innovation and Evaluation Study) investigation of a number commercial magnetic-fusion-energy (MFE) power-plant embodiments tokamak are summarized. These lessons apply to physics, engineering technology, environmental, safety, health (ES&H) characteristics projected power plants. A general conclusion this extensive potential plants is need for combined, symbiotic advances relative present understanding in engineering, materials before...
Energy confinement within the reversed field pinch (RFP) is governed by three plasma regions: a poorly confined core characterized parallel (radial) transport and flux surfaces destroyed m=1 tearing mode activity associated with dynamo relaxation; medium edge limited ideal pressure gradient driven modes; good region located near reversal layer. The determines global characteristics of RFP, and, if resistive interchange modes, would be consistent Connor-Taylor scaling that has provided fit to...
A description of the ARIES-III research effort is presented, and general features reactor are described. The plasma engineering fusion-power-core design summarized, including major results, key technical issues, central conclusions. Analyses have shown that power-balance window for D-/sup 3/He tokamak reactors small requires a first wall (or coating) highly reflective to synchrotron radiation values tau /sub ash// epsilon e/ (the ratio ash-particle energy confinement times in core plasma)....
The multi-institutional ARIES team has completed a series of four steady-state and two pulsed cost-optimized conceptual designs commercial tokamak fusion power plants. level assumed advances in technology physics was varied from one design to the next. cost benefits various options are compared quantitatively with an emphasis placed on versus operation. Possible means improve economic competitiveness suggested.
