The Steam Generating Team (SGT)—a joint venture of Framatome and United Engineers & Constructors Inc.—has completed a project to replace the Unit 2 steam generators at the Watts Bar nuclear plant, Framatome announced last week.
Watts Barr’s owner and operator, the Tennessee Valley Authority, awarded Framatome the contract for the work in early 2020.

Using basic hand tools and remote manipulators, operators at Savannah River Nuclear Solutions (SRNS) were able to reduce radiation exposure to workers performing cutter head maintenance in the Savannah River Site’s Tritium Extraction Facility (TEF).
According to SRNS, the innovative procedure proved to be an excellent example of real-world application of As Low As Reasonably Achievable (ALARA) principles of time, distance, and shielding.
