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.

A semiempirical method allowing description and normalization of the prompt fission neutron spectrum (PFNS) is proposed. The method is based on the assumption that PFNS 235U(nth,f) and 252Cf(SF) have similar shapes. In the case of these two isotopes, the method works with accuracy of 1 to 2% in the energy range of 0.1 to 10 MeV.
