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.

The Scientific Method—parsing a problem into isolated subproblems—is often necessarily employed in optimization efforts to reduce large and complex problems into more tractable parcels. However, adopting an ersatz action space relies on the assumption that the dependencies between each subproblem are weakly coupled. This paper first illustrates the not-insignificant distortion of objective space topology that can occur when optimizing over an ersatz action space for a lattice-scale problem. We then develop a novel method to recover from this distortion and loss of any optima therein. Sequential design and decision-making practice needs to be aware of and take steps to mitigate this potential pitfall.
