What's more, the helium nuclei generated during the experimental runs are colliding with fuel in the pellet, sparking
further fusion reactions.
But when the core has turned to iron,
no further fusion reactions are possible and gravity is unchallenged, so the star begins to collapse.
Not exact matches
ITER's objective is to go much
further and release 10 times as much energy as it will use to initiate the
fusion reaction.
You have those, you kind of solve a lot of the blanket problems where you have your
fusion blast in the center and then it hits a blanket which is basically nuclear waste, depleted waste, and there's a lot of left over energy in that waste; and you have neutrons hit that waste and then that catalyzes
further reactions, you get a lot more heat.
Their aim is to gain a better understanding of thermonuclear
reactions and, ultimately, how controlled nuclear
fusion, which has proved remarkably elusive so
far, could provide an alternative source of electrical energy.
The Department of Energy's Advanced Research Projects Agency - Energy (ARPA - E) has announced a two - year, $ 3.8 million award for Sandia National Laboratories and the University of Rochester's Laboratory for Laser Energetics (LLE) to study the potential of combining two different technologies to
further advance their research efforts to produce controlled
fusion reactions.
