First-of-a-kind Risk-informed Digital twin for Operational Decision Making
A digital twin (DT) is a digital model or a collection of models of a physical entity. DTs in the nuclear arena can be used from plant design through decommissioning. Decisions are typically a priori or made offline. Risk-informed decision making is identifying what can go wrong, its frequency, and the consequences of its failure. Ideally risk-informed decision making refl…

Criteria for Determining the Safety of Wireless Technologies at Nuclear Power Plants
This report provides an initial discussion of the potential impact to safety-related/important-to-safety (SR/ITS) systems by the possible expanded use of wireless technologies. One aspect of this discussion is focused on a review of Regulatory Guide (RG) 1.180 Rev. 2 to determine whether any revisions are necessary to reflect the current state of practice in evaluating and…

Nuclear Generating Stations and Transmission Grid Reliability
Nuclear generating stations have historically been susceptible to transmission system voltage excursions. When nuclear plants trip due to voltage excursions, the resulting loss of real and reactive power support can make grid events worse. New standards are being prepared which may help to improve nuclear plant and transmission system reliability. A brief historical perspe…
