What Are Supercritical CO2 Power Cycles?

While conventional power plant cycles produce power from turbines using water or steam as the working fluid, supercritical carbon dioxide (sCO2) cycles use CO2 that is in a supercritical state—at a temperature and pressure above its critical point where liquid and gas phases are not distinguishable.  CO2 has a relatively low critical pressure of 7.4 megapascal […]

MPW Mobile Ultrafiltration and Demineralization Units Exceed Canadian Power Plant Expectations

Challenge:
After a major refurbishment, a Canadian nuclear plant required additional process and boiler feed water for plant start-up and commissioning.
The plant’s raw water supply contained measurements ranging from 1-10 NTU, conductivity from 70-100 and color units ranging from 180-420. The plant also experienced highly variable flow rates, ranging from 0-600 GPM, and issues with the

The Economic Thicket of Generating Cost Comparisons

Comparing the costs of differing electric generating technologies has become popular among advocates for particular technologies and those seeking to find the optimal approach to new generation. While getting

Energy Resilience Demands Action—Just Not This One

In an apparent attempt to show supporters he is making good on his pledge to revive the dying coal industry, President Trump has been trying to find a way to funnel tens of billions of dollars to a small

Flexible Operation of Nuclear Power Plants Ramps Up

A widespread misconception persists that nuclear plants can only function as inflexible baseload sources of power—and it’s hurting prospects for the nuclear sector’s role in the world’s future power

Bipartisan Senators Move to Cement Nuclear Power’s Future

A wide-ranging bill introduced by a large group of bipartisan U.S. senators on March 27 seeks to cement the role advanced nuclear reactors will play in the nation’s future power mix.  The “Nuclear Energy Leadership Act” (NELA), aims to “reestablish U.S. leadership in nuclear energy,” which has been lost to state-sponsored development in Russia and […]

Bagging DOE Support, Westinghouse Eyes Demonstration for Nuclear Micro-reactor by 2022

The Department of Energy (DOE) is funding a project that would prepare Westinghouse’s 25-MWe eVinci micro-reactor for nuclear demonstration readiness by 2022.  The agency on March 27 said it will provide $12.9 million of the estimated $28.6 million Westinghouse needs for a project to prepare the micro-reactor for a demonstration, including for design, analysis, licensing […]

CEOs Say Preserving the Nuclear Power Fleet Is Imperative

Several power-sector CEOs—appearing at the Bloomberg New Energy Finance (BNEF) Summit in New York this week—suggested that existing nuclear power plants should not be allowed to slowly vanish from the U.S. electricity grid under market pressure caused by cheap natural gas and the growth of renewable energy. The leaders submitted that nuclear power provides important […]
