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.”

Evaluation of the radiological protection quantity E requires determining the dose deposited in different organs and tissues. This is why monitoring in exposed workplaces is ensured by dosimeters that are worn on the trunk and calibrated to measure the personal dose equivalent Hp(10) as an estimator of the effective dose E. However, the characteristics of the instrumentation and the definition of Hp(10) itself can result in significant differences between these two quantities. The Institute for Radiological Protection and Nuclear Safety Laboratory of Dosimetry for Ionizing Radiation in France is currently developing an instrumented anthropomorphic dummy allowing the evaluation of the effective dose for photon irradiation fields. For neutron fields, a preliminary numerical study has been done. The calculations were made using a mathematical anthropomorphic phantom, and the transport of irradiating particles was calculated using the Monte Carlo code MCNPX. The numerical study has been validated, and the results of some standard irradiations and differences between the effective dose and its estimator have been calculated for various realistic workplace simulations.
