More than 3000 stockholders around world were convened at summit to discuss how low-cost clean hydrogen production would be a huge step towards solving climate change. is dynamic fuel that can used across all industrial sectors lower carbon intensity. By 2030, hopes have developed means reduce current cost by 80%; i.e., USD 1 per kilogram. Because importance...

Abstract This work describes the integration of data acquisition (DAQ) hardware and software for purpose acquiring not only but real‐time transport model parameter estimates in context subsurface flow problems. Integrated DAQ estimation systems can be used to reduce storage requirements, trigger event recognition more detailed sampling actions, otherwise enhance remote monitoring capabilities. The contaminant problem is posed here as analogous heat transfer a three‐dimensional,...

It has been well known that nuclear power plant and coal-fired release some amount of radioactive materials during their normal operations. The purpose this study was to compare radiation exposure doses the public as a consequence airborne effluents released from plants under operation. NRCDose3 used estimate gaseous its operation while CAP88-PC calculate living around plant. results showed were less than those regulatory annual limits. Effective dose by external exposure, skin equivalent...

The research utilized advanced PCTRAN and RASCAL software to evaluate the potential radiological impacts of hypothetical accidents, specifically loss-of-coolant accident (LOCA) long-term station blackout (LTSBO), at El Dabaa Nuclear Power Plant. Over a span ten years, comprehensive meteorological data were meticulously analyzed assess dispersion radioactive substances within 40-kilometer radius across all four seasons. outcomes revealed that only in case LTSBO did levels surpass limits set...

Various products containing a small number of added radionuclides are commonly available for use worldwide. However, frequent such puts the public at risk radiation exposure. In this study, dose assessments to members using consumer naturally occurring radioactive materials (NORMs) were conducted various usage scenarios evaluate external and internal exposure dose. Data study obtained from previous literature statistically analyzed Boxplot determine input data assessment. A normalized value...

In February 2016, the Egyptian government introduced Vision 2030. An important pillar of this vision is energy. 2030 presented renewable energy as best solution to reduce emission greenhouse gases (GHGs) in sector. Egypt’s electricity comes from various power plants; conventional thermal plants generate over 90% which gas-fired generation accounts for 75% total output. Following increase natural gas (NG) projects Egypt, NG dominant source. Based on pillars sustainable development strategy...

The most recent assessments conducted by the International Energy Agency indicate that natural gas accounts for majority of Nigeria’s fossil fuel-derived electricity generation, with crude oil serving mostly as a backup source. Fossil fuel-generated represents 80% country’s total. In addition, carbon dioxide (CO2) emissions in Nigeria 2018 (101.3014 Mtons) demonstrated 3.83% increase from 2017. purpose this study is to suggest an alternate energy supply mix meet future electrical demand and...

A total of 33 680 nuclear power plants (NPPs) workers were monitored and recorded from 1990 to 2007. According the record, average individual radiation dose has been decreasing continually 3.20 mSv man−1 in 1.12 at end After International Commission on Radiological Protection 60 recommendation was generalised South Korea, no NPP received >20 radiation, numbers relatively highly exposed have continuously. The age distribution NPPs composed mainly 20–30 y olds (83 %) for 1990–1994 30–40 (75...

Uganda is looking forward to diversifying its energy system sustainably meet the present and future needs. To achieve this, country embarking on a nuclear power program construct large reactors, although this would increase Uganda’s electricity generation capacity, huge investments in construction grid expansion required presents big challenge considering small size of economy grid. Luckily, emerging new technologies, such as modular reactors (SMRs) can address these challenges due their...
