Converting Coal Power Plants to Nuclear Gains Steam

Cars That Think

Department of Energy (DOE) released a report suggesting that, in theory, over 300 former and present coal power plants could be converted to nuclear. Most nuclear plants around the world today are large light-water reactors, with capacities well over a gigawatt—quite a bit more than typical coal plants. On 13 September, the U.S.

New 3-step process for conversion of kraft lignin from black liquor into green diesel

Green Car Congress

The kraft process converts wood into wood pulp for paper production. The process produces a toxic byproduct referred to as black liquor—a primarily liquid mixture of pulping residues (such as lignin and hemicellulose) and inorganic chemicals from the Kraft process (sodium hydroxide and sodium sulfide, for example).

Researchers develop new catalysts for a direct Fischer-Tropsch to olefins (FTO) process

Green Car Congress

Researchers in the Netherlands have demonstrated the direct conversion of synthesis gas through a Fischer-Tropsch process to C 2 through C 4 light olefins with selectivity up to 60 wt.% using catalysts that constitute iron nanoparticles (promoted by sulfur plus sodium) homogeneously dispersed on weakly interactive ?-alumina

Study shows 99% of used lead-based vehicle batteries in the EU are collected and recycled

Green Car Congress

Other processes convert the spent electrolyte into calcium sulphate (gypsum) or sodium sulphate (soda), which can be used for various applications such as building products or detergents. In some processes the spent electrolyte is separated and filtered to make it suitable for regenerating fresh acid for a variety of applications.

China’s New Breeder Reactors May Produce More Than Just Watts

Cars That Think

Fast neutrons—that is, ones with 1 megaelectron-volt or more of kinetic energy—split the plutonium atoms, releasing secondary neutrons that are captured by the U-238 and convert some of that U-238 into plutonium. Liquid sodium is used as a coolant because it does not slow down neutrons as much as water does.

ARPA-E awards $38M to 12 projects leading used nuclear fuel recycling initiative

Green Car Congress

The US Department of Energy’s (DOE’s) Advanced Research Projects Agency - Energy (ARPA-E) will award $38 million to 12 projects that will work to reduce the impacts of light-water reactor used nuclear fuel (UNF) disposal. Earlier post.) It is later removed from the pools and placed into dry storage casks with protective shielding.

DIY Gamma-Ray Spectroscopy with a Raspberry Pi Pico

Cars That Think

You can buy various used scintillator crystals on eBay fairly cheaply: I purchased a small sodium iodide crystal, 18 millimeters in diameter and 30 mm long, for about US $40. A Raspberry Pi Pico [left] provides both compute power and the gamma-ray spectrometer’s analog-to-digital converter. James Provost. V the SiPM needs.
