Nonlinear Multivariate Regression Algorithms for Improving Precision of Multisensor Potentiometry in Analysis of Spent Nuclear Fuel Reprocessing Solutions

نویسندگان

چکیده

Potentiometric multisensor systems were shown to be very promising tools for the quantification of numerous analytes in complex radioactive samples deriving from spent nuclear fuel reprocessing. Traditional multivariate calibration these is performed with partial least squares regression—an intrinsically linear regression method that can provide suboptimal results when handling potentiometric signals multi-component samples. In this work, a thorough investigation was on performance system combination non-linear models PUREX (Plutonium–URanium EXtraction) process. The composed 17 cross-sensitive sensors plasticized polymeric membranes containing different lipophilic ligands capable heavy metals, lanthanides, and actinides binding. Regression algorithms such as support vector machines (SVM), random forest (RF), kernel-regularized (KRLS) tested compared traditional (PLS) simultaneous following elements aqueous phase process: U, La, Ce, Sm, Zr, Mo, Zn, Ru, Fe, Ca, Am, Cm. It methods outperformed PLS most analytes.

Cost analysis of the US spent nuclear fuel reprocessing facility

a r t i c l e i n f o The US Department of Energy is actively seeking ways in which to delay or obviate the need for additional nuclear waste repositories beyond Yucca Mountain. All of the realistic approaches require the reprocessing of spent nuclear fuel. However, the US currently lacks the infrastructure to do this and the costs of building and operating the required facilities are poorly es...

Spent Fuel Reprocessing: an Overview

India has entered in the field of spent fuel reprocessing as early as sixties by way of R&D studies and finalising the process flow sheet. India's first spent fuel reprocessing plant was commissioned in the year 1965 at Trombay to reprocess spent fuel arising from research reactors. The recovered plutonium is being utilised to feed various programmes of the department. With the passage of time,...

Modal Analysis of Spent Fuel Cask for WWER-1000 Reactors

The Spent Fuel Assemblies (SFAs) of WWER-1000 reactors are planned to be transported by special containers which are supposed to be designed in a manner to stand against vibrations and impacts in order to protect the spent fuel from any possible damage. The vibration opposition of these containers shall be far beyond the critical resonance, because the resonances about the natural frequency of ...
