Optical testing on the NOVA laser fusion program

Description: The optical testing part of the program requires characterizing index homogeneity of large blanks of fluorophosphate glass, optical surface figure and quality of large polished optics and performance of optical coatings such as antireflection, high reflectors and polarizing beam-splitters. For this purpose, a large effort is being expended to upgrade the optical test facilities at Lawrence Livermore Laboratory in preparation for the NOVA optics procurement. (MOW)

Development of impedance sensors at ORNL: for measurement of two-phase flows. [PWR]

Description: Techniques and equipment have been developed to measure in-vessel local void fraction and velocity in a reflood transient test facility. The two impedance sensors, the flag probe and the string probe, have been tested (prototype sensors) in a variety of air-water and steam-water facilities an in all cases acceptable measurement results were obtained.
