Modernizing I&C for operations and maintenance, one phase at a time
The two reactors at Dominion Energy’s Surry plant are among the oldest in the U.S. nuclear fleet. Yet when the plant celebrated its 50th anniversary in 2023, staff could raise a toast to the future. Surry was one of the first plants to file a subsequent license renewal (SLR) application, and in May 2021, it became official: the plant was licensed to operate for a full 80 years, extending its reactors’ lifespans into 2052 and 2053.

In the framework of optimization of confinement properties of Uragan-2M, neoclassical transport in the 1/ regime and the pertinent stored energy are studied. A rather wide range of device configurations is considered. For the computations the field line following code NEO for computation of transport measures is used. Computations are performed in real-space coordinates using the magnetic field produced by the device coils. The difference of currents in adjacent groups of toroidal field (TF) coils as well as the current in the TF coils and the additional vertical magnetic field are used as varying parameters.Some possibilities for improving the 1/ transport corresponding to optimum values of the varying parameters are presented.
