Flexible cubic spline interpolation (open access)

Flexible cubic spline interpolation

This report describes a simple, efficient, and flexible program for cubic spline interpolation in one dimension, suitable for inclusion in the ANL Subroutine Library and in an interactive timesharing system. Most of the cubic spline programs already available either restrict the boundary conditions to knowledge of the first derivative at both end points, or require the second derivatives to vanish at these points. The program described here removes these restrictions and enables the user to adopt boundary conditions appropriate for his own problem. The advantage is demonstrated for the extreme case of interpolating the function x log (1/x), which has singularities in all its derivatives at x = 0.

Pu, U redistribution in (U,Pu)O/sub 2/ fuels by temperature gradients (open access)

Pu, U redistribution in (U,Pu)O/sub 2/ fuels by temperature gradients

A predictive model of the time-dependent evolution of radial Pu/U + Pu gradients in operating nonmolten mixed oxide fuels is being developed. This model is based on preferential evaporation-condensation and vapor transport of metal-bearing species either along cracks and porosity channels within the fuel or inside closed pores migrating up the temperature gradient; equilibrium thermodynamics are applied to calculate the continually changing vapor composition over the hot fuel. Predictions of the model are used in combination with recent in-pile experimental data (from nonmolten mixed oxide fuel pins irradiated in EBR-II from 0.2 to about 11 at. % burnup at varying powers) to delineate the key parameters in radial actinide redistribution. A correlation between fuel stoichiometry (O-to-Pu ratio) and the degree of redistribution (described by an enrichment factor ..gamma../sub Pu/) identified, however, the degree of restructuring of the fuel - as determined by the peak linear power rating, time at this power, and the initial fuel density - also has a strong influence on the final value of ..gamma../sub Pu/. Certain kinetic features of the process and intended modifications to the present model are discussed, and evidence for axial actinide vapor transport in an irradiated annular fuel is also presented.

Proposal for (p,p) and (p,n) Collision Experiments at Batavia by Use of Nuclear Emulsions and Electronic Detectors (open access)

Proposal for (p,p) and (p,n) Collision Experiments at Batavia by Use of Nuclear Emulsions and Electronic Detectors

In this project we propose to measure: (1) the elastic differential cross-sections of 100-500 GeV protons in (p,p) collisions by use of nuclear emulsions, and (2) the energy spectrum and d{sigma}/dEd{Omega} of the light fragments {sub 1}H{sup 2}, {sub 1}H{sup 3}, {sub 2}He{sup 3}, {sub 2}He{sup 4} in (p,N) collisions at the same energy range using the electronic E-{Delta}E detectors.
