Abstract
Ultrasonic thermometry, based on the temperature dependence of sound velocity in solids, has been demonstrated under ideal laboratory conditions beyond 6000R. Integrated fluxes (nvt) of 2.6 × 1019 fast and 8.7 × 1019 thermal do not perturb the velocity/temperature relationship. Ta protective sheaths prevented carbon contamination for 1 hr at 5100R, in a program simulating temperature measurements in the graphite/hydrogen atmosphere of a nuclear rocket engine. Tests have also been performed in liquid sodium at 1200R, and separately, inside a 1.6 mm dia Ta tube heated to 5500R, simulating temperatures inside UO2-fueled pins of fast breeder reactors.Keywords
