It is a tank-type 6 megawatt reactor [2] that is moderated and cooled by light water and uses heavy water as a reflector. It is the second largest university-based research reactor in the U.S. (after the University of Missouri Research Reactor Center) and has been in operation since 1958. [7] It is the fourth-oldest operating reactor in the ...
In December 2012, Areva estimated that the full cost of building the reactor will be about €8.5 billion, or almost three times the original delivery price of €3 billion. [5] [6] [7] The economics of nuclear power are debated. Some opponents of nuclear power cite cost as the main challenge for the technology.
ARC is planned to be a 270 MWe tokamak reactor with a major radius of 3.3 m, a minor radius of 1.1 m, and an on-axis magnetic field of 9.2 T. [ 2 ] The design point has a fusion energy gain factor Q p ≈ 13.6 (the plasma produces 13 times more fusion energy than is required to heat it), yet is fully non-inductive, with a bootstrap fraction of ...
Those blueprints contained designs for a power plant with a 100-megawatt pressurized water reactor. [3] The OPEN100 plans aim to standardize nuclear power plant construction to increase speed and cost-effectiveness, allowing plants to be built in under two years for a cost of $300 million. [ 4 ]
The reactors, known as Unit 3 and Unit 4 were originally expected to be completed in 2017 and cost $14 billion, but the second reactor only started commercial operations in April this year.
SPARC is designed to achieve this with margin in excess of breakeven and may be capable of achieving up to 140 MW of fusion power for 10 second bursts despite its relatively compact size. [ 2 ] [ 1 ] The project is scheduled to start operations in 2026, with the goal of demonstrating net power (Q > 1) in 2027. [ 4 ]
Using A4W data [5] with a 25% increase in thermal power, the A1B reactors are likely to produce enough steam to generate 125 megawatts (168,000 hp) of electricity, plus 350,000 shaft horsepower (260 MW) from just one reactor to power the four propeller shafts. [6]
The reactor unit has a thermal capacity of 250 MW, and two reactors are connected to a single steam turbine to generate 210 MW of electricity. [70] Its potential applications include direct replacement of supercritical coal-fired power plants, [ 71 ] [ 72 ] while its heat could be used for seawater desalination, hydrogen production, or a wide ...
