The UK Government is accelerating plans for homegrown power, and nuclear energy is a significant part of its strategy. The target is eight reactors by 2030, with a target of one nuclear reactor per year instead of one per decade. The government wants 24GW of nuclear energy by 2050, satisfying up to 25% ...
Electrical distribution can be easily overlooked in daily life. It’s out of sight and mind – electrical equipment is concealed within unassuming metal boxes and substations, while transmission lines run under our streets or are suspended above them. It can be easy to forget that distribution is a crucial element of our electrified world, a fact we are reminded of when the lights go ...
Society has responded to increasing power demands with technology such as nuclear fission. Fission splits uranium into smaller elements and releases large amounts of energy used to heat water in nuclear reactors and ultimately produce electricity. ...
Niobium is used in the manufacture of products for diverse applications: -High temperature vacuum furnaces, where it is an excellent getter -Nickel based superalloys; and alloyed with titanium or tin -Superconductors -Sodium vapor lamps, where it is resistant to attack by the molten alkali -Synthetic diamonds -Sputtering targets for fiber optic applications or architectural glass ...
Steam generator tubes are among the most vital safety barriers within pressurized nuclear reactors (PWRs), and underlying defects can degrade the tubing material and damage the entire steam generator, causing severe problems that can endanger crew members and the public. ...
Worldwide electricity generation from nuclear power increases from 2.5 trillion kWh in 2012 to 3.7 trillion kWh in 2040, as concerns about energy security and greenhouse gas emissions support the development of new nuclear generating capacity, but reactor retirements and opposition from local populations keep nuclear from ...
Nuclear reactor coolant removal monitored by hydrogen measurements provided by Systech's 542 programmable gas analyzers NNC Limited is using Systech's 542 programmable gas analyzers to monitor hydrogen off-gas in test rig for Dounreay Fast Breeder Reactor decommissioning. Decommissioning nuclear ...
Transatomic power, a company started by two MIT PhD candidates, came up with a new approach to safer and cheaper nuclear reactors. Utilizing molten salt reactors, which has not really been used commercially and so far is only existed in paper, the technology is promised to cut initial cost and increase safety. Today’s conventional ...
No matter the outcome of any one presidential election, reports show that about 90% of the existing nuclear reactors in the country are soon due to be relicensed for an additional 20 years, some for as long as 40 years — far outlasting the tenure of any president. Furthermore, the U.S. is projected to remain the biggest global producer of ...
Nuclear energy is going through a major resurgence in popularity, especially when it comes to nuclear energy investment. ...
According to the Union of Concerned Scientists, the actual costs of 75 of the first nuclear reactors built in the U.S. ran over initial estimates by more than 200 percent. ...

Martin, whose previous book outlined the case for thorium as a substitute for uranium in nuclear reactors, takes the reader on a tour of coal mining operations and power plants from Appalachia to northwestern China, where the coal industry remains a linchpin of the economy and a rare source of decent-paying jobs. ...
In this paper, an efficient numerical procedure for calculating the solution of the non–linear neutron point kinetics equations in the field of nuclear reactor dynamics is presented. The explicit finite difference method is applied to solve the non–linear neutron point kinetics equations with temperature feedback reactivity. ...
This study presents the effect of temperature, fouling factor and salinity of the condenser cooling seawater and adverse effect on the thermal performance of a nuclear power plant. These are the most important factors affecting the condenser performance. The study is carried out on a pressurised water reactor nuclear power plant. The results ...
China, the country that is building more nuclear reactors than any other, continued to get more electricity from the wind than from nuclear power plants in 2014. ...
I started investigating Georgia Power’s policies in regards to the two nuclear reactors they’re building at Plant Vogtle. I did my own research. ...

Application Moisture is measured in helium gas used for nuclear reactors. The helium is used as a reactor coolant because of its excellent thermal properties and chemical inertness. Problem If the helium becomes contaminated with moisture, it will cause both degradation of graphite rods and an undesired change in the process's heat balance. At ...
In the process of nuclear core design, reactor cell parameters such as dimensions, enrichment and materials must be adjusted considering restrictions such as the average thermal flux, criticality and sub–moderation. This problem may be formulated using global optimisation methods in order to generate sets of design parameters to be analysed by programs that ...
The High–Temperature Gas–cooled Reactor (HTGR) is designed with outlet temperatures ranging between 750°C and 800°C. ...
