Reactor on molten salts and fast neutrons

29.11.2021

TerraPower, which is heavily funded by Bill Gates, is also developing the Molten Chloride Experimental Reactor (MCRE) along with the Natrium reactor project. Like the Natrium project, the MCRE reactor is powered by the radioactive decay of the fuel by absorbing fast neutrons, but in the case of the MCRE, the molten salt serves as both a coolant and a means of supplying fuel to the reactor. This is a winning combination.

The construction and operation of the MCRE reactor will be carried out by the Southern Company, a major operator of a range of generating facilities in the United States. The Southern Company recently signed an agreement with the US Department of Energy to design, build and operate the Molten Chloride Experimental Reactor (MCRE) at the Idaho National Laboratory (INL) site. In addition to TerraPower, Southern Company and INL, Core Power, Orano Federal Services, Electric Power Research Institute and 3M Company are participating in the project.

The US Department of Energy has allocated tens of millions of dollars for this project for several years in a row. TerraPower is also developing a marine version of the MCRE, the m-MSR, likely for the US Navy. The money is part of a five-year program that aims to provide information for the design, licensing and operation of a demonstration reactor.

TerraPower's MCFR technology uses molten salt as a coolant and fuel feed to the reactor, enabling so-called fast spectrum, which the company says makes the fission reaction more efficient. The plant operates at higher temperatures than conventional reactors, generates electricity more efficiently, and also offers the potential to use process heat and store (storage) heat for later generation.

The existence of an entropy rule for quantum entanglement has been proven 09.05.2024

Quantum mechanics continues to amaze us with its mysterious phenomena and unexpected discoveries. Recently, Bartosz Regula from the RIKEN Center for Quantum Computing and Ludovico Lamy from the University of Amsterdam presented a new discovery that concerns quantum entanglement and its relation to entropy. Quantum entanglement plays an important role in modern quantum information science and technology. However, the complexity of its structure makes understanding and managing it challenging. Regulus and Lamy's discovery shows that quantum entanglement follows an entropy rule similar to that for classical systems. This discovery opens new perspectives in the field of quantum information science and technology, deepening our understanding of quantum entanglement and its connection to thermodynamics. The results of the study indicate the possibility of reversibility of entanglement transformations, which could greatly simplify their use in various quantum technologies. Opening a new rule ... >>

New method for creating powerful batteries 08.05.2024

With the development of technology and the expanding use of electronics, the issue of creating efficient and safe energy sources is becoming increasingly urgent. Researchers at the University of Queensland have unveiled a new approach to creating high-power zinc-based batteries that could change the landscape of the energy industry. One of the main problems with traditional water-based rechargeable batteries was their low voltage, which limited their use in modern devices. But thanks to a new method developed by scientists, this drawback has been successfully overcome. As part of their research, scientists turned to a special organic compound - catechol. It turned out to be an important component that can improve battery stability and increase its efficiency. This approach has led to a significant increase in the voltage of zinc-ion batteries, making them more competitive. According to scientists, such batteries have several advantages. They have b ... >>

Alcohol content of warm beer 07.05.2024

Beer, as one of the most common alcoholic drinks, has its own unique taste, which can change depending on the temperature of consumption. A new study by an international team of scientists has found that beer temperature has a significant impact on the perception of alcoholic taste. The study, led by materials scientist Lei Jiang, found that at different temperatures, ethanol and water molecules form different types of clusters, which affects the perception of alcoholic taste. At low temperatures, more pyramid-like clusters form, which reduces the pungency of the "ethanol" taste and makes the drink taste less alcoholic. On the contrary, as the temperature increases, the clusters become more chain-like, resulting in a more pronounced alcoholic taste. This explains why the taste of some alcoholic drinks, such as baijiu, can change depending on temperature. The data obtained opens up new prospects for beverage manufacturers, ... >>

Curly hair is a natural defense against the summer heat. 29.06.2023

Scientists from the University of Southern California (USA) found that people with curly hair tolerate heat better.

The researchers conducted a series of laboratory experiments on a human head model. While maintaining a temperature of 35 °C, corresponding to the warmth of the scalp, they irradiated the model with a heat lamp. The model had different types of hair: straight, slightly curly, very curly, as well as a model with a completely bald head. The skin was either dry or moist.

The results showed that thick curls provide the best protection from the sun. Under them, the artificial skin almost did not heat up. Scientists believe that our ancestors in Africa survived, including thanks to their curls: under the burning sun, thick curls helped ancient people retain water in the body longer.

"The results of the study do not surprise me. Curls protect the head not only from the scorching sun, but also from the cold. In addition, the scalp is better ventilated. Nowadays, in the summer, this is an ideal image not only for women, but also for men. curls, can consider himself lucky,” says stylist Maurice Klostermann from Berlin.
