The Stirling engine together with a solar concentrator represents a solution for increasing energy efficiency. Thus, within the National Research and Development Institute for Cryogenic and Isotopic Technologies, an automation system was designed and implemented in order to control the processes inside the solar conversion unit using a programmable logic controller from Schneider Electric. The acquired parameters from the installed sensors were monitored using Unity Pro L software. The main objective of this paper is to solve the starting, operating, and shut-down sequences in safe conditions, as well as monitor the working parameters.
Based upon the authors' long experience and upon a literature review, this paper presents an assessment regarding up-to-date R&D activities related to development and application of liquid phase catalytic exchange (LPCE) technology for tritium separation from tritiated water, produced in fission and fusion nuclear reactors. The assessment is focused on key elements of the LPCE process, mixed catalytic packing and as a result of the assessment, few recommendations for selecting the most suitable mixed catalytic packing are given. A new improved mixed catalytic packing (COMPACK C-P 001) was manufactured and proposed to be used in the future Tritium Removal Facility from Cernavoda CANDU NPP (Romania).
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
