Book excerpt: Stress corrosion cracking can potentially cause fuel failures at circumferential ridges in the sheath. finite element computer codes elestres and feast are used to calculate two-dimensional, axisymmetric, elastic-plastic sheath stresses at and near the circumferential ridges. the level of stresses is given by the fuel design (such as pellet/sheath diameters, pellet length, pellet density) and by the operating conditions (such as power history). the accuracy, convergence, and cost of the stress calculations, however, are determined by the discretization used in the calculations: the number of nodes in the finite element mesh; the shape of the individual finite elements; the pattern into which the finite elements are arranged; and the size of the calculation-steps into which the power history is subdivided. in this study, we determined the discretization that gives a reasonable compromise of accuracy, convergence, and cost for the stress calculations. the highest accuracy is obtained by using triangular finite elements of aspect ratios close to one, and assembling them into hexagonal patterns. to caputure the stress gradients, five nodes are required across the sheath wall at the ridge, but two nodes are sufficient near the midplane of the pellet. the resulting mesh contains about 200 nodes and about 300 finite elements. calculation-steps of 6 kw/m provide a convergent solution, with a factor of two margin against numerical divergence. with the above arrangement, feast needs about 2.4 seconds on a cdc/cyber 175 computer to calculate sheath stresses per calculation-step. six radial nodes at the ridge would double the computing cost. decreasing the size of the calculation-steps means more calculations are needed to analyze a given power history, giving a linear increase in computing cost.

Book excerpt: "In accordance with Federal government policy, contracting-out continues to play an important role in CANMET research. CANMET R & D is organized in a program-activity structure in which there are two main programs - Energy Research and Minerals Research, each with several activities. Summaries in this report are arranged according to this structure. The purpose of the report is to inform both the public and private sectors about technology stemming from CANMET's contracting-out policy"--Foreword, p. i.

Book excerpt: "This report summarizes energy related R & D contracts which were sponsored by CANMET and completed in 1982 and 1983. The summaries were prepared to assist in transferring to industry the new technology which has been created through CANMET's extensive contracting-out program. In fiscal year 1982-83, the value of energy related R & D which was contracted-out exceeded $8.5 million, representing 23% of the CANMET Energy Technology Activity budget for the year. Energy contracts completed prior to 1982 were summarized previously in CANMET Reports 78-1, 79-26 and 82-11"--Foreword, page i.
