We present preliminary diameters and albedos for 7956 asteroids detected in the first year of the NEOWISE Reactivation mission. Of those, 201 are near-Earth asteroids and 7755 are Main Belt or Mars-crossing asteroids. 17% of these objects have not been previously characterized using the Near-Earth Object Wide-field Infrared Survey Explorer, or NEOWISE thermal measurements. Diameters are determined to an accuracy of similar to 20% or better. If good-quality H magnitudes are available, albedos can be determined to within similar to 40% or better.
