Quality is key: Investing in advanced nuclear research for tomorrow’s grid
As the energy sector faces mounting pressure to grow at an unprecedented pace while maintaining reliability and affordability, nuclear technology remains an essential component of the long-term solution. Southern Company stands out among U.S. utilities for its proactive role in shaping these next-generation systems—not just as a future customer, but as a hands-on innovator.

Rigorous tests of the Monte Carlo transport code MCNP have been performed by measuring the efficiency of a 6Li-glass moderating neutron detector using Lucite as the moderator relative to the efficiency of the detector using mineral oil as the moderator, and comparing this with the MCNP predicted value. The tests were done using both 252Cf fission-source neutrons and 1.2-MeV neutrons produced by a Van de Graaff accelerator.
