Abstract Solar radiation modification (SRM) reflects sunlight back into space and could rapidly cool Earth, potentially reducing the harms of dangerous climate change. Current international law fails to directly comprehensively address transboundary, regional global governance challenges that SRM presents. Various ideas for have emerged, drawing on multiple areas existing law. This article offers a critical review literature analyses its applicability governance. First, would ‘directly’...
In the HINDAS program, nuclear data in 20-2000 MeV range are evaluated by means of a combination tmodels and well-selected intermediate- high-energy experiments. A panoply European accelerators is utilized to provide complete sets experimental for iron, lead uranium over large energy range. Nuclear model codes being improved validated against these new data. This should result enhanced ENDF-formatted libraries up 200 MeV, cross sections transport above MeV. The impact models will be directly...
AbstractA series of experiments on a mercury spallation target using high-peak-power GeV proton-beam from the Alternating Gradient Synchrotron (AGS) Brookhaven National Laboratory (BNL) has been performed under an international collaboration among laboratories in Japan, U.S. and Europe, namely ASTE (AGS Spallation Target Experiment) collaboration. This paper reviews current status neutronic performance target.Keywords: Mercury targetGeV proton-beamAlternating SynchrotronNeutron spatial...
Experiments in a subcritical assembly with pebble-bed high-temperature gas-cooled reactor fuel and hydrogen ranging between 0 14.4 vol% were carried out to study the effects of water ingress on reactivity test accuracy diffusion-code calculations for small systems. Special emphasis is given an adequate description influence diffusion properties system. The agreement experimental theoretical results all cases better than ±0.01 keff.
Several fuel-loading concepts are proposed for high-temperature reactors of the pebble-bed type. A very promising one is so-called OTTO (once through then out) loading scheme. Some intrinsic features fuel axial nonsymmetrical power and neutron flux distribution with a pronounced maximum at upper reactor core region. Since physics cores will be different from previous homogeneous schemes, detailed experimental theoretical investigations these objectives were performed critical facility...
For light water reactors, loss of coolant is an important point in safety analysis, whereas for gas-cooled reactors the ingress into core region incident relevance. The applicability computer code system GAMTEREX to pebble beds spherical high-temperature reactor fuel elements with simulated verified by experiment. measurements were performed at a Siemens-Argonaut reactor, using its ring as driver zone pebble-bed center reactor.
Investigation of the initial core poisoning pebble bed high temperature reactor has been made by experiments and checking computations. In following example thorium high-temperature THTR-300, THTR absorber elements poisoned with hafnium-boron were added to fuel graphite KAHTER core. Three different loadings, corresponding 2.7, 5.3, 8% reactivity compensation, used in experiments. For purposes comparison, two cores exclusively boron also studied. The these corresponds 2.7 respectively.The...
For pebble bed reactors, the problem exists that an in-core instrumentation is not possible. As a flux mapping method, we have developed three-dimensional code ZELT-3D, which reconstructs distribution in core using detector signals of side reflector as input. The results calculation utilizing this and its associated theory for perturbation distributions by absorber rods show perturbed fluxes possible positions rod tips can be detected well. We think method serve to locate xenon oscillations,...
