Abstract

An arrangement is provided for controlling neutron albedo in toroidal fusion devices having inboard and outboard vacuum vessel walls for containment of the neutrons of a fusion plasma. Neutron albedo material is disposed immediately adjacent the inboard wall, and is movable, preferably in vertical directions, so as to be brought into and out of neutron modifying communication with the fusion neutrons. Neutron albedo material preferably comprises a liquid form, but may also take pebble, stringer and curtain-like forms. A neutron flux valve, rotatable about a vertical axis is also disclosed.

Variable control of neutron albedo in toroidal fusion devices

Patent Jassby, D L ; Micklich, B J

This patent describes a toroidal fusion plasma device, including a vacuum vessel for confining a plasma which contains fusion neutrons. The vacuum vessel has inboard and outboard walls, a arrangement for varying, between steady state operating modes, one of the flux and the energy spectrum of the fusion neutrons which are incident on the outboard wall. The arrangement comprises: neutron reflective material exclusively disposed immediately adjacent the inboard wall so as to reflect ones of the fusion neutrons having a predetermined flux and energy spectrum onto a predetermined portion of the outboard wall; and means for positioning the neutron reflectivemore »« less

Patent Jassby, D L ; Micklich, B J

This invention pertains to methods of controlling in the steady state, neutron albedo in toroidal fusion devices, and in particular, to methods of controlling the flux and energy distribution of collided neutrons which are incident on an outboard wall of a toroidal fusion device.
Control of neutron albedo in toroidal fusion reactors

Technical Report Micklich, B J ; Jassby, D L

The MCNP and ANISN codes have been used to obtain basic neutron albedo data for materials of interest for fusion applications. Simple physical models are presented which explain albedo dependence on pre- and post-reflection variables. The angular distribution of reflected neutrons. The energy spectra of reflected neutrons are presented, and it is shown that substantial variations in the total neutron current at the outboard wall of a torus can be effected by changing materials behind the inboard wall. Analyses show that a maximum of four isolated incident-current environments may be established simultaneously on the outboard side of a torus. Withmore »« less

Control of neutron albedo in toroidal fusion reactors

Conference Micklich, B J ; Jassby, D L - Nucl. Technol./Fusion; (United States)

The MCNP and ANISN codes have been used to obtain basic neutron albedo data for materials of interest for fusion applications. Simple physical models are presented which explain albedo dependence on pre- and post-reflection variables. The angular distribution of reflected neutrons is found to be roughly costheta for all materials and all incident energies and angles. The energy spectra of reflected neutrons are presented, and it is shown that substantial variations in the total current at the outboard wall of a torus can be effected by changing materials behind the inboard wall. Analyses show that a maximum of four isolatedmore »« less
Control of neutron albedo in toroidal fusion reactors

Thesis/Dissertation Micklich, B J

Neutron albedo effects in toroidal fusion reactors are evaluated to determine how altering the albedo of blanket regions can be used to improve the neutronics characteristics of experimental or power reactors. Basic neutron albedo data for materials of interest in fusion applications are calculated with the ANISN and MCNP codes. Total albedos are shown to vary directly with material cross sections, and the angular distribution of reflected neutrons is approximately cos theta for thick slabs and flatter for thin ones. Equations describing the physics of neutron multiplication and reflection are used to construct a fast-neutron albedo model that provides themore »« less
