“…To estimate tritium inventories at Wincheringen and Koblenz, mass budgets of tritium were estimated following Santschi et al (1987) and Hanslik et al (2017). For this purpose, we calculated the product of the monthly mean composite tritium data and simulated monthly discharge derived from the hydrodynamic 1D model HYDRAX for the period of 2017 to 2022 (Oppermann et al, 2015).…”

“…Various studies used natural tracers combining 222 Rn (hereinafter: radon) with ions, stable water isotopes δ 18 O and δ 2 H, or radioactive isotope 3 H (hereinafter: tritium) to investigate GSI at larger scales (Atkinson et al, 2014; Cook, 2013; Schubert et al, 2020). To identify losing stream conditions, techniques are more diveres and include measuring radon attenuation in groundwater (Schubert et al, 2006), radon combined with transient storage modelling (e.g., Bourke et al, 2014), assigning δ 2 H end‐member mixing models (e.g., Engel et al, 2022), analysing diurnal oscillations of electrical conductivity and radon residence times (Vogt et al, 2010), and calculating mass budgets of tritium (Hanslik et al, 2017; Santschi et al, 1987). However, the majority of these studies focused on GSI at the reach scale and experimental field studies rarely investigated GSI at regional scales.…”

Groundwater‐surface water interactions (GSI) connect rivers and streams with riparian areas and the adjacent aquifer. Although these interactions exert a substantial control of quantity and quality of both groundwater and surface water, knowledge on GSI along rivers at the regional scale, particularly for inland waterways, is still limited. We investigated GSI along the river Moselle, an important federal inland waterway in Germany, by using radon and tritium to identify gaining (water flux from the aquifer to the surface water) and losing (water flux from the surface water to the aquifer) stream conditions, respectively. Gaining stream conditions were identified by continuously measuring radon along the river during boat surveys with a high spatial resolution (every 2 km) during intermediate (October 2020) and near low flow conditions (August/September 2021). The tritium concentrations in surface water and groundwater and the resulting tritium inventories were used to characterize losing stream conditions Monthly tritium inventories from 2017 to 2022 revealed a mean loss for the whole period of 20.3 % and a mean gain of 21.8%. Both were probably triggered by a combination of losing stream conditions and flood‐induced mass transfer of water from the aquifer back into the river as well as discharge fluctuations. At the investigated site Lehmen there were direct indications of an influence of surface water due to elevated tritium concentrations in the groundwater (up to 13.3 Bq L−1). Using radon mass balance modelling, good agreements of simulated versus measured radon data with respect to two groundwater end‐member scenarios were obtained during intermediate flow (Spearman's ρ: 0.97 and 0.99; MAE: 10.1 and 3.4 Bq L−1) and near low flow (Spearman's ρ: 0.97 and 0.99; MAE: 11 and 6.5 Bq L−1). Considerable groundwater inflow was limited to the meander of Detzem, where cumulated groundwater inflow of about 19 m3 s−1 (9.5% of total discharge) and 4.2 m3 s−1 (3.8% of total discharge) was simulated during intermediate and near low flow, respectively. However, the groundwater inflow was relatively low compared to alpine streams, for example. The study will help to better identify and quantify GSI at the regional scale and provide methodological guidance for future studies focusing on inland waterways.

“…Tritium is also produced as a by-product of the operation of nuclear reactors such as various nuclear power plants. 9,10 Tritium is mainly released in the form of HTO vapor from the nuclear power plants. Once released into the atmosphere, HTO can be incorporated into plants or soil moisture.…”

To analyze the tritium internal exposure dose of workers in the Third Qinshan Nuclear Power Plant over the past 15 years. Urine samples provided by workers are tested directly to analyze the tritium concentrations and estimate internal exposure dose. Since 2004, an average of approximately 1600 workers have been monitored annually, with an average annual monitoring frequency of approximately 11 000. Since 2004, the average annual collective dose of tritium internal exposure was 149.62 person·mSv, accounting for 19.07% of the total annual collective dose. A total of 18 workers’ annual individual internal tritium radiation doses exceeded 2 mSv, of which 5 workers’ internal tritium radiation doses in a single intake exceeded 2 mSv. The occupational population with the largest total internal tritium radiation doses consists of maintenance personnel, fuel operators, and radiation protection personnel, whose collective doses of internal exposure account for 75.51% of the total collective doses within the plant. Over 15 years of operation, the internal tritium radiation doses of workers in the Third Qinshan Nuclear Power Plant have been strictly controlled within the national regulatory limit and power plant management target, ensuring the health and safety of the workers.

“…However, the influence on the local natural ecosystem showed a negative impact when the woody biomass was not appropriately utilized. Meanwhile, the wastewater treatment and post-treatment drying techniques also play a crucial role in the fertilizer value of biosolids [39]. Benić et al [10] investigated the potential use of a novel direct driven electro-hydraulic system for articulated forestry tractors (skidders), considering the significantly high energy efficiencies of such systems with respect to the classical electro-hydraulic systems.…”

Sustainability has become a broad societal goal, aiming to ensure that human beings coexist safely and harmoniously with nature over a longer time. The influence of the COVID-19 pandemic on the global economy is coming to an end. The development and merits of sustainable energy supply, advanced technology, and economic features have received significant attention over the last few decades. However, significant gaps still exist with respect to how to design, construct, and implement hybrid and optimal energy systems with the lowest investment and cost. Since 2002, the Sustainable Development of Energy, Water, and Environment Systems (SDEWES) conferences have become a significant meeting venue for researchers to introduce, discuss, share, and disseminate novel concepts and ideas. This paper presents an overview of published articles in the Special Issues (SIs) dedicated by the series SDEWES conferences, especially those published in Energies recommended by the 16th SDEWES Conference, which was held on 10–15 October 2021 in Dubrovnik, Croatia. This SI in Energies focused on four main topics, including the application of renewable bioenergy, component enhancement in renewable systems, sustainable development for buildings and economic analysis and evaluation for sustainability. The collected papers provide insight into the topics related to recent advances in improving sustainable efficiency, including studies on waste-to-wealth techniques, utilization of hybrid bioenergy systems, heat exchangers and other components for performance enhancement, energy supply and demand analysis, low-temperature DHC systems, techno-economic assessment, and environmental evaluation.
