Plant Design

China’s CAP1400—a reactor design based on Westinghouse’s AP1000 pressurized water reactor—has successfully passed the International Atomic Energy Agency’s (IAEA’s) Generic Reactor Safety Review. The milestone is significant for China, which plans to deploy the advanced reactor design in large numbers (Figure 4) as well as export the technology. 4. On the nuclear horizon. An artist’s […]

When gas-fired plants are required to cycle more than they were designed for, added stress on plant components isn’t the only consequence. You also need to pay closer attention to turbine catalyst systems. Traditionally, many combined cycle gas turbine (CCGT) power plant units were designed and permitted for a baseload or similar operating profile. Startups […]

When owners of the Big Stone Plant researched air quality control system technology, they considered all available options and eventually settled on a design that was not in widespread use. Now that the

Is waste-to-energy the best greenhouse gas fighter among electric generating technologies? Or do trash burners spew dangerous air emissions? The answer may be a surprise. What electricity-generating technology results in net greenhouse gas (GHG) reductions, not just zero new emissions? According to the U.S. Environmental Protection Agency (EPA), it’s not nuclear, not wind, not solar. […]

Although it’s not widely publicized, a majority of the energy used to generate electricity is wasted in the form of heat discharged to the environment. For better or worse, that’s just the way a typical thermal power plant works. Fuel, such as coal, biomass, natural gas, or uranium (in the case of nuclear plants), is […]

The nuclear industry has been expecting big things from small modular reactors (SMRs) for a long time, but to date, no SMRs have reached commercial construction phase. That may change soon. Utah Associated Municipal Power Systems has a plan to deploy NuScale Power’s Integral Pressurized Water Reactor at a site in Idaho. Will others follow […]

Power generators have always had to make afetyome changes as each new generation enters the sector, but today’s new workers are bringing with them attitudes and skills that challenge traditional plant management, for good and ill. Here’s what some companies and plants are doing to make the best use of younger workers while getting them […]

An industry rooted in tradition is facing unprecedented changes and challenges, and meeting them requires “thinking big” and embracing disruptive technologies that will change how we think about electricity generation and delivery. That was the message from the keynote session at ELECTRIC POWER 2016.  Two senior power sector executives opened the 2016 ELECTRIC POWER Conference […]

The Department of Energy (DOE) is ready to end its involvement with the Texas Clean Energy Project (TCEP), a carbon capture, utilization, and storage (CCUS) facility under development in west Texas, a move that would effectively shut the project down, according to its backers. Along with FutureGen, Hydrogen Energy California (HECA), and NRG’s Petra Nova […]

Fuel cells powered by natural gas, biogas, and hydrogen are a rapidly expanding option for distributed generation, with fuel cell­­–based power plants being deployed in capacities into tens of megawatts. But as the technology improves and costs begin to scale, opportunities for other applications are being explored. One such application may even go beyond power […]
