Acoustic measurement of penetration of liquid sodium into limestone concrete

An acoustic, pulse-echo technique has been used as part of the large-scale, sodium/concrete interaction tests being conducted at Sandia Laboratories to measure the penetration of a large pool (up to 186 kg) of liquid sodium (initial temperature as high as 600/degree/C) into a limestone concrete crucible. This paper reports the acoustic results from four test, sodium/concrete interaction test program being conducted at Sandia Laboratories. 11 refs.
