Available in PDF, EPUB and Kindle. Book excerpt: The final hardware modifications for tritium operation have been completed for the Tokamak Fusion Test Reactor (TFTR). These activities include preparation of the tritium gas handling system, installation of additional neutron shielding, conversion of the toroidal field coil cooling system from water to a Fluorinet{sup {trademark}} system, modification of the vacuum system to handle tritium, preparation and testing of the neutral beam system for tritium operation and a final deuterium-deuterium (D-D) run to simulate expected deuterium-tritium (D-T) operation. Testing of the tritium system with low concentration tritium has successfully begun. Simulation of trace and high power D-T experiments using D-D have been performed. The physics objectives of D-T operation are production of ∼ 10 megawatts (MW) of fusion power, evaluation of confinement and heating in deuterium-tritium plasmas, evaluation of ?-particle heating of electrons, and collective effects driven by alpha particles and testing of diagnostics for confined ?-particles. Experimental results and theoretical modeling in support of the D-T experiments are reviewed.

Book excerpt: The Tokamak Fusion Test Reactor (TFTR) has performed initial high-power experiments with the plasma fueled by deuterium and tritium to nominally equal densities. Compared to pure deuterium plasmas, the energy stored in the electron and ions increased by ∼20%. These increases indicate improvements in confinement associated with the use of tritium and possibly heating of electrons by ?-particles.

Download or read book Deuterium Tritium Simulations of the Enhanced Reversed Shear Mode in the Tokamak Fusion Test Reactor written by and published by . This book was released on 2001 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The potential performance, in deuterium-tritium plasmas, of a new enhanced con nement regime with reversed magnetic shear (ERS mode) is assessed. The equilibrium conditions for an ERS mode plasma are estimated by solving the plasma transport equations using the thermal and particle dif- fusivities measured in a short duration ERS mode discharge in the Tokamak Fusion Test Reactor[F.M. Levinton, et al., Phys. Rev. Letters, 75, 4417, (1995)]. The plasma performance depends strongly on Zeff and neutral beam penetration to the core. The steady state projections typically have a central electron density of[approx]2:5x10 20 m[sup -3] and nearly equal central electron and ion temperatures of[approx]10 keV. In time dependent simulations the peak fusion power, [approx] 25 MW, is twice the steady state level. Peak performance occurs during the density rise when the central ion temperature is close to the optimal value of[approx] 15 keV. The simulated pressure profiles can be stable to ideal MHD instabilities with toroidal mode number n= 1, 2, 3, 4 and[infinity] for[beta][sub norm] up to 2.5; the simulations have[beta][sub norm][le] 2.1. The enhanced reversed shear mode may thus provide an opportunity to conduct alpha physics experiments in conditions imilar to those proposed for advanced tokamak reactors.

Download or read book Design of Tritium Breeding Experiments for the Tokamak Fusion Test Reactor written by and published by . This book was released on 1981 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Among intense fusion-neutron generators of the 1980's, the unique features of the TFTR are a geometrically extended D-T fusion-neutron source and a neutron spectrum, including backscattered neutrons, characteristic of a practical toroidal fusion reactor. It is planned to install a tritium-breeding module on the TFTR in order to take advantage of this opportunity to obtain reactor-relevant integral neutronics data and breeding rate profiles. These data will be combined with the measured neutron source parameters and the spatially dependent fusion-neutron fluence for comparison with the predictions of neutronics design codes. The results of this program will help determine the blanket coverage factors needed to achieve tritium self-sufficiency in future toroidal reactors. A preliminary conceptual design of a TFTR blanket module has been completed, utilizing lithium oxide as the tritium breeding material.

Available in PDF, EPUB and Kindle. Book excerpt: A primary objective of the Tokamak Fusion Test Reactor Project (TFTR) is to demonstrate the production of fusion energy using the deuterium--tritium fusion reaction in a magnetically confined plasma system. This paper will discuss the various tritium control methods employed to minimize the release of tritium to the environment. The methods to be described include the containment and ALAP philosophy, engineered safety features, redundant tritium cleanup systems, redundant instrumentation and control systems, interlocks, monitoring systems, management controls, and waste handling systems. Estimates will be included concerning the impact of routine and accidental tritium releases with these control systems in place.
