MIT Researchers Say Their Fusion Reactor Is “Very Likely to Work”
By Victor Tangermann
A team of researchers at MIT and other
institutions say their “SPARC” compact fusion reactor should actually work— at
least in theory, as they argue in a series of recently released research
papers.
In a total of seven papers penned by 47
researchers from 12 institutions, the team argues that no unexpected
impediments or surprises have shown up during the planning stages.
In other words, the research “confirms
that the design we’re working on is very likely to work,” Martin Greenwald,
deputy director of MIT’s Plasma Science and Fusion Center and project lead, told The New York Times.
Fusion power remains elusive, but the
tech promises to one day become a safe and clean way of producing energy by
fusing atomic nuclei together like the Sun. Despite almost a century of
research, though, nobody has managed to pull it off yet.
SPARC, one of the largest privately
funded project of its kind in the field, would be a first of its kind: a
“burning plasma” reactor that fuses hydrogen isotopes to form helium, with no
other input of energy needed.
Thanks to progress in the field of
superconducting magnets, the team hopes to achieve the same performance as far
larger reactors, such as the gigantic ITER (International Thermonuclear
Experimental Reactor) reactor, which started assembly in July.
The magnets are used to contain the
extremely hot and high pressure reactions going on inside the reactor, one of
fusion’s greatest challenges.
According to the team’s calculations,
SPARC should be able to produce twice as much fusion energy compared to the
amount needed to generate the reaction. That would be a massive jump, since no
researchers have managed to break even yet.
In fact, in the papers, the researchers
note it could be theoretically possible to generate ten times the amount —
though there’s plenty of work ahead before they could say that for sure.
The MIT team is hoping to construct its
compact reactor over the next three to four years, with the eventual goal of
generating electricity starting in 2035, the Times reports.
“What we’re trying to do is put the
project on the firmest possible physics basis, so that we’re confident about
how it’s going to perform, and then to provide guidance and answer questions
for the engineering design as it proceeds,” Greenwald said in an official
statement.
