Division Spotlight
Decommissioning & Environmental Sciences
The mission of the Decommissioning and Environmental Sciences (DES) Division is to promote the development and use of those skills and technologies associated with the use of nuclear energy and the optimal management and stewardship of the environment, sustainable development, decommissioning, remediation, reutilization, and long-term surveillance and maintenance of nuclear-related installations, and sites. The target audience for this effort is the membership of the Division, the Society, and the public at large.

Vogtle-3 shuts down for valve issue
One of the new Vogtle units in Georgia was shut down unexpectedly on Monday last week for a valve issue that has since been investigated and repaired. According to multiple local news outlets, Georgia Power reported on July 17 that Unit 3 was back in service.
Southern Company spokesperson Jacob Hawkins confirmed that Vogtle-3 went off line at 9:25 p.m. local time on July 8 “due to lowering water levels in the steam generators caused by a valve issue on one of the three main feedwater pumps.”

A system of nuclear transmutation is presented in which fission products and transuranics (TRU) are incinerated using 14-MeV neutrons produced by muoncatalyzed fusion (µCF) and a subcritical core composed of fission products and TRU, The 14-MeV neutrons produced by µCF are used to transmute 90Sr (fission product) by the (n,2n) reaction. The outcoming neutrons from the 90Sr cell transmute TRU through fission reactions and 99Tc through (n, γ) reactions. This fission energy is converted into electric energy to supply 4 GeV-25 mA deuteron beam power, which is used to produce µ− mesons. We also evaluate the production of tritium that is consumed as a fuel for µCF. The feasibility of the system was analyzed by the MCNP Monte Carlo neutron transport code. The results show that this system can be subcritical and can transmute fission products and TRU with an incineration half-life of ∼1 yr and that the deuteron beam energy and tritium fuel required to operate the system can be supplied within the system cycle itself.
