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.

Fully 3-dimensional model for Monte-Carlo simulation code (DEGAS) was newly applied in the GAMMA 10 central cell. Based on the measurement and DEGAS simulation, neutral transport during the gas puffing and neutral beam injection (NBI) in the central cell is investigated. The predicted H profile using DEGAS well explained the experimental result. It is clarified that the localized neutral source has much influence on the behavior of neutral particles in the plasma. In this paper, detailed discussion is shown from the view point of both the experiment and the simulation.
