“…The main objectives are to improve the capacity to plan, develop and implement safe, environmentally friendly and effective strategies and technologies for the management of spent nuclear fuel. In addition, one of the major tasks of cooperation between states is the need to identify and solve technological problems related to the use of spent nuclear fuel, management flexibility, and the analysis of future scenarios [32,49]. It should be noted that these theses are in line with our study, which describes a model of cooperation between states in the context of spent nuclear fuel reprocessing and storage management.…”

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.

“…MOX fuel is widely used in nuclear power plants in Belgium, France, Germany and Switzerland. In Japan, twelve nuclear power plants are also licensed to use MOX fuel, and a MOX fuel fabrication facility is being licensed [31][32][33][34]. In the future, MOX fuel will be adapted for more modern reactors, such as PHWR and LMR.…”

“…Other reports stated that the significant decrease of over 5% in Q1 2020 global energy demand has brought about a The MCO is unlikely to significantly decrease the total electricity production since Malaysia is a small country with low electricity production of 12,000 to 13,000 GWh monthly [12]. Other reports stated that the significant decrease of over 5% in Q1 2020 global energy demand has brought about a substantial decline in the CO 2 emissions as compared to Q1 2019, which stem from disruptions of transport systems and industrial sectors of the economy, as well as the reduction in products and services demands [1,23]. In [1], and even more rapid decrease was projected across the remaining nine months of 2020 with the predicted reduction value of 30.6 Gt of carbon.…”

Atmospheric Carbon Dioxide and Electricity Production Due to Lockdown

et al. 2020

We analyzed real-time measurements of atmospheric carbon dioxide (CO2), with total electricity production and nationwide restrictions phases in China, the United States of America, Europe, and India due to the novel coronavirus COVID-19 pandemic and its effects on atmospheric CO2. A decline of 3.7% in the global energy demand at about 150 million tonnes of oil equivalent (Mtoe) in the first quarter (Q1) of 2020 was recorded compared to Q1 2019 due to the cutback on international economic activities. Our results showed that: (1) electricity production for the same period in 2018, 2019, and 2020 shrunk at an offset of 9.20%, which resulted in a modest reduction (−1.79%) of atmospheric CO2 to the 2017–2018 CO2 level; (2) a non-seasonal, abrupt, and brief atmospheric CO2 decrease by 0.85% in mid-February 2020 could be due to Phase 1 restrictions in China. The results indicate that electricity production reduction is significant to the short-term variability of atmospheric CO2. It also highlights China’s significant contribution to atmospheric CO2, which suggests that, without the national restriction of activities, CO2 concentration is set to exceed 2019 by 1.79%. Due to the lockdown, it quickly decreased and sustained for two months. The results underscore atmospheric CO2 reductions on the monthly time scale that can be achieved if electricity production from combustible sources was slashed. The result could be useful for cost-benefit analyses on the decrease in electricity production of combustible sources and the impact of this reduction on atmospheric CO2.

“…The Taiwan Power Company (TPC) owns and operates two nuclear power reactors (Maanshan 1 and 2, PWR), with a further four BWR units having been shutdown (Chinshan 1 and 2, Kuosheng 1 and 2) and two advanced BWR units (Lungmen 1 and 2) never commissioned. [ 1 ] The spent nuclear fuel is currently safely managed in dry storage, with a long‐term plan for permanent disposal in a deep geological repository (DGR) based on the KBS‐3 concept developed by SKB using copper canisters surrounded by highly compacted bentonite buffer material (Figure 1 [ 2 ] ). Because candidate sites for a DGR have not yet been selected in Taiwan, experience from countries in the process of site selection, such as the United States, United Kingdom, Canada, and Japan, is also being considered.…”

A 1‐D reactive‐transport model has been developed to describe the production and transport of sulfide in a deep geological repository in crystalline rock and the subsequent corrosion of the copper canister. The model accounts for various processes, including: (i) the microbial reduction of sulfate by organotrophic and lithotrophic sulfate‐reducing bacteria, (ii) the supply of sulfate from both the ground water and from the dissolution of gypsum present as an accessory mineral in the bentonite buffer, (iii) diffusive transport of reactants and products, and (iv) sequestration of a fraction of the microbially produced sulfide by precipitation as mackinawite. The results of a base case simulation and of sensitivity analyses indicate that the extent of uniform corrosion is approximately 0.2 mm after 1 million years and that the maximum flux of sulfide to the canister surface is below the threshold for localized corrosion or stress corrosion cracking.
