Nuclear Fusion Summary - Prospects for breakthrough commercial reactors 2018-2025
http://nextbigfuture.com/2013/05/nuclear-fusion-summary.html
[...]Helion Energy and MSNW - John Slough Designs
Helion Energy Fusion Engine has received about $7 million in funds from DOE, the Department of Defense and NASA. They had already received $5 million which they used to build a one third scale proof of concept. The company hopes to raise another $2 million by next year, $35 million in 2015-17, and $200 million for its pilot plant stage.
The MSNW LLC (sister company to Helion Energy working on Space fusion) does refer to the Helion Energy work. MSNW is working on a NASA grant to develop direct nuclear fusion space propulsion. They have said they will demonstrate net energy gain within 6-24 months.
Fusions Assumption:
• Ionization cost is 75 MJ/kg
• Coupling Efficiency to liner is 50%
• Thrust conversation ~ 90%
• Realistic liner mass are 0.28 kg to 0.41 kg
• Corresponds to a Gain of 50 to 500
• Ignition Factor of 5
• Safety margin of 2: GF =GF(calc.)/2
Mission Assumptions:
• Mass of Payload= 61 mT
• Habitat 31 mT
• Aeroshell 16 mT
• Descent System 14 mT
• Specific Mass of capacitors ~ 1 J/kg
• Specific Mass of Solar Electric Panels 200 W/kg
• Tankage fraction of 10% (tanks, structure, radiator, etc.)
• Payload mass fraction =Play load Mass
• System Specific Mass = Dry Mass/SEP (kg/kW)
• Analysis for single transit optimal transit to Mars
• Full propulsive braking for Mar Capture - no aerobraking
The Fusion Engine is a cyclically operating fusion power plant technology that will be capable of clean energy generation for base load and on-demand power.
The Fusion Engine is a 28-meter long, 3-meter high bow tie-shaped device that at both ends converts gases of deuterium and tritium (isotopes of hydrogen) into plasmoids - plasma contained by a magnetic field through a process called FRC (field-reversed configuration). It magnetically accelerates the plasmoids down long tapered tubes until they collide and compress in a central chamber wrapped by a magnetic coil that induces them to combine into helium atoms. The process also releases neutrons.
The Helion Energy Fusion Engine provides energy in two ways. Like in a fission reactor, the energy of the scattered neutrons gives off heat that ultimately drives a turbine. Helion is also developing a technique that directly converts energy to electricity. The direct conversion will provide about 70 percent of the outgoing electricity according to Kirtley.
Helion Energy new plan is to build a 50-MWe pilot of its “Fusion Engine” by 2019 after which licensees will begin building commercial models by 2022.
Lockheed Skunkworks Fusion - Targeting Commercial by 2023
Lockheed presented at Google Solve for X a 100MW compact fusion reactor concept that would run on deuterium and tritium (isotopes of hydrogen). It would fit on a truck and be built on a production line like jet engines.
Breakthrough technology: Charles Chase and his team at Lockheed have developed a High Beta configuration, which allows a compact reactor design and speedier development timeline (5 years instead of 30).
* The magnetic field increases the farther that you go out, which pushes the plasma back in.
* It also has very few open field lines (very few paths for the plasma to leak out)
* Very good arch curvature of the field lines
* The Lockheed system has a beta of about 1.
* This system is DT (deuterium - tritium)
Currently a cylinder 1 meter wide and 2 meters tall. The 100 MW version would be about twice the dimensions.[...]
Pływająca elektrownia atomowa bliska ukończenia
http://www.geekweek.pl/aktualnosci/16832/p...iska-ukonczenia
[...]Już teraz zainteresowanie pływającą elektrownią atomową wyraziły kraje takie jak Chiny, Indonezja, Malezja, Algieria, Namibia czy Argentyna.
Może jeszcze Rosjanie zrobią na tym biznes 🙄
