Management of the Energy and Economic Potential of Nuclear Waste Use

Abstract

Recently, issues related to the effects (benefit or harm) of processing nuclear waste and its further use as fuel have been increasingly often raised in the scientific discussion. In this regard, the research aims to investigate issues related to the assessment of the economic potential of nuclear waste use, as well as the cooperation between states in the context of the reduction of risks associated with nuclear waste storage and processing. The research methodology is based on an integrated approach, including statistical, factor analysis, and the proposed system of performance indicators for managing spent nuclear fuel use. The research was carried out on the basis of materials from Russia and the EU countries. In the course of the study, a model of cooperation between states has been developed (based on the example of technologies and methods of processing nuclear waste used in the EU and Russia) according to the nuclear waste (spent nuclear fuel) management algorithm. The model considers the risks and threats associated with ecology and safety. The developments and other results described in the study should be used in further research devoted to the use of nuclear waste as heat-producing elements.

“…As a result of improper disposal, toxic pollution and heavy metals enter the environment. Waste left in fields and near water tanks is eaten by terrestrial and aquatic animals, which affects environmental degradation [6].…”

A Cucurbit[8]uril‐Based Supramolecular Framework Material for Reversible Iodine Capture in the Vapor Phase and Solution

“…Nuclear power plants' reactors hold significant quantities of radioactive material that, in DOI: 10.1002/smll.202308175 the event of an accident, might endanger both humans and the environment. [3,4] Among the products of nuclear fission, radioactive iodine is a highly reactive halogen that can cause thyroid disease and cancer, and it is also an important pollutant in the air and water. [5,6] With its potent ability to migrate, radioactivity, and extraordinarily long radioactive half-life (≈ 1.57 × 10 7 years), 129 I has the potential to permanently contaminate the environment.…”

“…[28,29] These materials have better iodine adsorption performance than zeolites due to their adjustable porosity and huge specific surface area. Besides, a number of supramolecular macrocyclic compounds have been successively reported for iodine adsorption applications, such as pillar[n]arenes, [30,31] calix [4]pyrroles, [32,33] and cucurbit[n]urils. [34,35] Among them, cucurbit[n]uril (Q[n]) acts as a traditional macrocyclic host synthesized by the condensation of glycoluril and formaldehyde in the presence of acid.…”
