The Transformational Challenge Reactor (TCR) program was launched in 2019 to demonstrate that highly improved, efficient systems can be created rapidly by harnessing the major advances in manufacturing, materials, and computational sciences that have emerged since the end of the first nuclear era. The Department of Energy’s Oak Ridge National Laboratory leads the TCR program, which includes contributing partners from other DOE national laboratories and the U.S. nuclear industry. The program leverages some of the nation’s leading scientists and engineers and draws from ORNL’s lengthy history, institutional knowledge, and capabilities in high--performance computing, materials science development, advanced manufacturing techniques, and nuclear science and engineering.

The Tennessee Valley Authority has begun a refueling and maintenance outage at Browns Ferry-2 that includes the largest scope of turbine deck work since the unit’s construction, as well as innovations in fuel assembly components, the utility announced on March 1.
On deck: All three of the 1,254.7-MWe boiling water reactor’s low-pressure turbines will undergo a comprehensive replacement of major components, including new rotors, inner casings, steam piping and bellows, and turbine supervisory instruments, requiring the support of more than 500 additional outage workers. TVA said that 600 crane lifts will need to be performed for some components, such as the rotors, which weigh up to 327,888 lb., and inner casings, which weigh up to 200,000 lb.
