NRC approves St. Lucie SLRs
The Nuclear Regulatory Commission has approved subsequent license renewals for St. Lucie Units 1 and 2, extending the operating licenses for the pressurized water reactors by another 20 years.
Tuesday’s approval means that the 1,062-MWe Unit 1 and 1,074-MWe Unit 2 can now operate until March 1, 2056, and April 6, 2063, respectively. Unit 1 commenced operations in 1976 and Unit 2 in 1983. With the original 40-year operating licenses and first 20-year renewals, these second 20-year renewals bring the reactors’ lifespan to 80 years.

Session Organizer:
With increased high-performance computing (HPC) capabilities, multiphysics codes for reactor applications can be powerful in simulating complex reactor behavior for advanced reactors and the current fleet of light water reactors. There are many advantages to simulating reactor behavior with multiphysics codes, and they can aid in the design and licensing of reactor concepts. However, there are challenges to coupling codes simulating various physical phenomena including working with different time scales, meshes, units etc. which will be discussed. In addition, the panel discussions will include additional issues such as verification and validation of multiphysics codes and software usability by analysts who are not subject matter experts in all physical phenomena being simulated.
