France ’s WEST optical fusion nuclear reactor has shattered a nuclear fusion record set byChinajust a few weeks ago , label yet another little but significant step on the road toward nigh - limitless light energy .
The CEA ’s ( Commissariat à l’énergie atomique et aux énergies alternatives ) WEST tokamak atomic fusion reactor maintain a steady closed circuit of burning plasma for a record 1,337 minute , fit in to a Feb. 18announcement — beating China’sprevious 1,066 - second benchmark , rig on Jan. 20 , by 25 % .
A glimpse inside the WEST tokamak.
" western United States has achieved a raw fundamental technological milepost by keep hydrogen plasma for more than twenty transactions through the injection of 2 MW of heating power,“Anne - Isabelle Etienvre , CEA film director of fundamental enquiry , said in a statement . ( 2 megawatt being enough to powermore than 1,000 habitation ) . " experiment will continue with increase power . ”
Scientists have been taste to rein in the power of nuclear coalition — the cognitive operation that powers the star — for more than 70 years . By coalesce hydrogen mote together under extremely high pressures and temperatures , star convert matter into twinkle and heating system , generating tremendous amounts of energy without producinggreenhouse gasesor long - lasting radioactive barren .

But duplicate the status found inside the hearts of stars is no dim-witted task . The most vernacular and advanced invention for optical fusion reactor is called a tokamak . The tokamak works by superheating plasma ( one of the four states ofmatter , consisting of positive ions and negatively charged free electron ) and moderate it inside a donut - shaped reactor sleeping room with powerfulmagnetic fields .
To reach its new milepost , the WEST nuclear reactor did just this , corralling blood plasma made from great hydrogen isotopes that was combust hotter than 50 million degrees Celsius for more than 22 instant .

preparation blood plasma to these temperature is the relatively easy part , but finding a elbow room to corral it so that it does n’t burn through the reactor without also ruining the fusion process is technically foxy . This is usually done either with optical maser or magnetic force field .
The accomplishment pave the mode for the eventual operation of the International Thermonuclear Experimental Reactor ( ITER ) fusion nuclear reactor , a labor that fetch together China , the European Union , India , Japan , South Korea , Russia and the United States to hunt down the largest fusion nuclear reactor ever .
" This excellent result allow both WEST and the Gallic community to lead the way for the future habit of ITER , " Etienvre said .
dwell of 19 massive whorl looped into multiple toroidal magnets , ITER was in the first place slate to lead off its first full test in 2020 , but revisions to its schedule mean it will first firein 2039 at the earliest . This means the engineering is unconvincing toprogress quick enoughto be a virtual solution to theclimate crisis .
