The original title was "Vogtle Unit 3 Enters Commercial Operation: First ‘Newly Constructed’ U.S. Nuclear Power Plant in Decades" but that was longer than the title limit.
This snippet from the article explains the ‘Newly Constructed‘ distinction:
Prior to Vogtle Unit 3, the newest reactor to enter service in the U.S. was the Tennessee Valley Authority’s Watts Bar Unit 2, which came online in 2016. However, Watts Bar Unit 2 was technically a deferred unit, construction of which began in the 1970s. Therefore, Southern Company has long considered the Vogtle project the first “newly constructed” reactor to be built in the U.S. since at least Comanche Peak Unit 2, which entered commercial operation in August 1993, or Watts Bar Unit 1, which entered service in May 1996.
