LMFBR fuel component costs

Description: A significant portion of the cost of fabricating LMFBR fuels is in the non-fuel components such as fuel pin cladding, fuel assembly ducts and end fittings. The contribution of these to fuel fabrication costs, based on FFTF experience and extrapolated to large LMFBR fuel loadings, is discussed. The extrapolation considers the expected effects of LMFBR development programs in progress on non-fuel component costs.

Debugging in a multi-processor environment

Description: The Supervisory Control and Diagnostic System (SCDS) for the Mirror Fusion Test Facility (MFTF) consists of nine 32-bit minicomputers arranged in a tightly coupled distributed computer system utilizing a share memory as the data exchange medium. Debugging of more than one program in the multi-processor environment is a difficult process. This paper describes what new tools were developed and how the testing of software is performed in the SCDS for the MFTF project.

Heat pipes for use in a magnetic field

Description: A heat pipe configuration is described for use in a magnetic field environment of a fusion reactor. Heat pipes for operation in a magnetic field when liquid metal working fluids are used are optimized by flattening of the heat pipes having an unobstructed annulus which significantly reduces the adverse side region effect of the prior known cylindrically configured heat pipes. The flattened heat pipes operating in a magnetic field can remove 2 to 3 times the heat as a cylindrical heat pipe of th… more

DC gradient-B pumping of tandem-mirror thermal barriers

Description: Passive pumping of tandem-mirror thermal barriers by a combination of E x B and gradient magnetic field (grad-B) drifts has the advantages of engineering simplicity, low power consumption and selectivity in pumping out trapped thermal ions while retaining high-energy sloshing ions, hot electrons, and central-cell ions. Specifically, installing dc perturbation coils in suitable locations utilizes the differences in the turning points of these populations. In addition, we can dispose of the therm… more

Boundary layer studies related to fusion theory. Final report

Description: The described work studied the boundary between closed and open field lines in EBT geometry, with emphasis on the microstability properties. These properties were established primarily for drift waves in the lower hybrid range of frequencies. The transport due to these modes was evaluated by a self-consistent treatment, using quasilinear models in a plasma diffusion code. The model was benchmarked against the EDT experimental results from ORNL and the sensitivity to transport model established.… more

Photovoltaic mechanisms in polycrystalline thin-film silicon solar cells. Quarterly technical progress report No. 2, 1 November 1980-31 January 1981

Description: Results described in this report clearly indicate that high quality small area diodes can be fabricated with negligible edge effects. It is shown that these devices can be used to determine carrier transport mechanisms, which, in turn, are related to the nature of defects present in the substrate. The sectioning technique, in conjunction with other techniques described previously, enables a detailed analysis of the nature of defects (and their propagation paths). A unified approach towards appl… more

Plasma confinement in the TMX tandem mirror

Description: Plasma confinement in the Tandem Mirror Experiment (TMX) is described. Axially confining potentials are shown to exist throughout the central 20-cm core of TMX. Axial electron-confinement time is up to 100 times that of single-cell mirror machines. Radial transport of ions is smaller than axial transport near the axis. It has two parts at large radii: nonambipolar, in rough agreement with predictions from resonant-neoclassical transport theory, and ambipolar, observed near the plasma edge under… more

k-line iterative methods: a conjugate-gradient approach

Description: The generalized conjugate gradient scheme based on the k-line block Jacobi splitting A = M-N was studied for solving model two-dimensional parabolic and elliptic difference equations AU = F tilde. A represents the matrix ch/sup ..cap alpha../-h/sup 2/..delta../sub h/. Eigenvalues of M/sup -1/N cluster, and the cluster radii decrease as ch/sup ..cap alpha../ or k increases. Computations with k = 4, 8, 16, 32, and ch/sup ..cap alpha../ = 0, h, 2 are discussed.
