GSE Solutions announced that it has developed key services that support recent Topical Report, which outlines the requirements for using Data Validation and Reconciliation (DVR) for Measurement Uncertainty Recapture (MUR). In July 2023, the Nuclear Regulatory Commission (NRC) released the final safety evaluation of the Topical Report submitted for applying DVR to MUR uprates. DVR is the new elite standard for optimizing plant performance in the nuclear power industry and can now be used to implement uprates of up to approximately 1.4%.

GSE's Engineering, Programs & Performance group (formerly True North Consulting) uses Belsim's VALI modeling software to pull the plant data from a historian, perform the reconciliation calculations, and output a reconciled data set representing the process's most probable true state. Then, the GSE team uses data analytics to monitor, troubleshoot, and make operational improvements that increase plant output and ensure efficient and safe operations, providing significant economic benefits to the utility. The cost of the DVR service is approximately $0.4 million to $0.5 million per unit, with approximately half the plants in the US having performed an MUR.
