Bd. Keele et al., NONDESTRUCTIVE IN-SITU MEASUREMENT OF RADIOLOGICAL DISTRIBUTIONS IN HANFORD SITE WASTE TANKS, IEEE transactions on nuclear science, 43(3), 1996, pp. 1821-1826
Measurement of radiological materials in defense nuclear waste stored
in underground tanks at the Hanford Site is being used to indicate mat
erial distributions. Both safety assessment and future processing chal
lenges are dependent on knowledge of the distribution, kinds, and quan
tities of various key components. Data from CdTe and neutron detector
measurements are shown and correlated with physical sampling and labor
atory results. The multiple assay approach is shown to increase the co
nfidence about the material distributions. As a result, costs of physi
cal sampling and destructive analyses can be controlled while not seve
rely limiting the uncertainty of results.
