Book excerpt: A chf look-up table, applicable for both the loss-of-regulation (lor) and loss-of-coolant (loc) accident conditions, has been derived for a string of horizontal, candu-type, 37-element bundles. the bundle-chf look-up table is primarily based on the chf table for tubes and the correction factors accounting for the differences in geometry (between tubes and bundles) and in channel orientation (between vertical and horizontal flows). experimental results of chf in bundles are subsequently used to improve the accuracy of the table. the table-chf values have been adjusted to provide a correct and smooth parametric trend. within the ranges of experimental data, the prediction accuracy of the chf look-up table for bundles is excellent: rms errors are 4.6 percent for the data from the 6-m uniformly heated bundles, 5.8 percent from the 3-m uniformly heated bundles, 7.4 percent from the 1-m uniformly heated bundles and 6.8 percent for the initial dryout data from the 6-m non-uniformly heated bundles. predictions from the chf look-up table for bundles have also been compared against the bundle chf results obtained with freon-12, using the h2o/f-12 modelling parameters. these freon chf tests covered a range of mass flux from 1200-7450 kg.m-2.s-1 (water equivalent conditions). the overall rms error for four separate horizontal bundle-chf tests is 6.33 percent and for five vertical bundle-chf tests it is 5.09 percent. outside the ranges of the data base, the effect of flow stratification has been accounted for in the bundle-chf table by employing a semi-empirical correction factor which is obtained from a balance of turbulent force and gravitational forces. at conditions corresponding to stratified smooth or stratified wavy flow, the table values are equal to zero.

This book was released on 1985 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fission product release and redistribution was studied during the exposure of uo2 in a zirconium furnace tube to steam and air at temperatures up to 910 degrees c. the fuel fragments had been exposed to less than or equal to 3.11 x 10 sup(18) n/cm sup(2) (0.3 mw.h/kg) at less than or equal to 70 degrees c in the self-serve facility of nrx. under these conditions no diffusion to grain boundaries should have occurred, and fission products should stay randomly scattered throughout the matrix. releases were small, less than or equal to 1.4 percent with only xenon and iodine being significant. the fuel oxidation occurred predominantly at less than or equal to 700 degrees c. at higher temperatures oxidation of the zirconium occurred and protected the fuel from significant high temperature oxidation. the results illustrate that fission gases distributed in the fuel matrix are not released during simple crystallographic re-arrangement. release occurs only when an atomic site or gas bubble is intersected by a crack or dislocation. significantly higher release should be expected under conditions where grain growth occurs. selective traps for fission products performed well and will be further investigated in future studies.

Available in PDF, EPUB and Kindle. Book excerpt: Electrical and mechanical transients were used to simulate acoustic emission (ae) signals expected during a crack-growth experiment by temperature-pressure cycling of a pressure tube. electric noise simulated heater noise, while mechanical transients from pencil-lead breaks and ballpoint-pen impacts on a pressure tube, respectively simulated ae from crack growth and mechanical noise in an operating fuel channel. simulations were used, before cycling, to assess the method's capability to discriminate against noise, calibrate instruments for sensitivity, and interpret ae events observed during cycling. digital signal processing (dsp) techniques, using correlation and frequency analyses, were applied to digitized transients. results show that: (i) a spatial filter on the ae instrument provides about 60 db discrimination against extraneous electrical and mechanical noise, (ii) ae bursts from ballpoint-pen impacts and pencil-lead breaks, on a pressure tube, contain low (
