Sustainable Controlled Fusion Reactor

Sustainable Controlled Fusion Reactor

Have a hopper that dispenses a small amount of fusion-fuel into a dispenser at high pressure. The dispenser has two stages, one to move the fuel from a main tank, to a secondary tank, and this connection cannot be open as the second stage that dispenses the fusion-fuel from the second-stage into reaction chamber. This prevents the reaction from spreading into the fuel-tank.

This allows the power plant the ability to limit the amount of fuel that is input into the reactor, and this then allows them to control the size of the reaction and limit it to a controllable level.

The reactor is able to contain a very small fusion reaction, and is able to keep this sustained by adding very small amounts of fuel, nano grams, pico grams, or even smaller amounts such as femto grams of fuel would be added at time, at a continuous rate to allow the chain-reaction to continue to occur without allowing it to grow out of control.

This may be difficult and require precise timing of release of a drip of fuel down to very minute increments of time, as the chain-reaction seems to occur near instantaneously, but the fuel would be added at the time where the reaction would still be prone to inducing the fusion reaction within the niblet of fuel with the reaction currently taking place.

These niblets of fuel would have to be introduced at very high velocity from a very tiny tube, propelled at a high pressure ensuring that the pipe is completely cleared of the material to ensure that the proportions required to sustain the reaction are met.

Using inert gas to do this would increase the volume within the chamber, and this could effect the reaction in negative ways. Instead of increasing the pressure by increasing the amount of chemicals in the volume, the pressure is increased by decreasing the total volume of the area.

This would look much like a tiny pipe with a tiny piston driving into it.

The fuel is released from the primary tank into the secondary tank, then this access route is closed off.

While the entrance to the reactor is closed, the secondary-tank (a very tiny tank) collapses to force the fuel into the feed tube, and the piston is lowered into the feed-tube to separate it from the secondary tank. The pressure is increased by driving the piston into the feed tube, and once this has sufficient pressure to ensure that the fuel will clear the tube,  to see to it that the reaction will not occur within the tube, but rather in the reactor, the feed-tube opens into the reactor to allow the fuel to enter.

This may leave a small part of the feed-tube exposed to the reaction, so this section of the tube must be able to withstand the fusion reaction and not be destroyed or warped in any way.

Rather than having reliable mechanical parts to open and close during this process, which may be difficult, one can have a latch that opens when the pressure applied by the feed-tube piston exceeds that provided by the reaction; if the reaction is still volatile enough, it will begin to fuse the fuel, and this increase in pressure would close the latch tightly again until the reaction has diminished enough for another niblet of reactor fuel to enter the chamber. This may happen in very tiny fractions of a second, so these parts must be able to move at exceptionally fast speeds. To allow this to be more plausible, the feed-tube can be relatively short, to see that the piston does not have to travel very far up and down between each fuel-intake and fuel-import.

The reactor may have to be started by traditional means of fusion, similar to a fusion bomb, but once the reaction has started, this process should be able to allow the reaction to continue indefinitely. A reactor such as this would have a very limited range of function capacity in terms of variability of fuel input and power output, as the amount of force produced by the reaction must be enough to securely close the latch into the feed tube, while the pressure from the piston must be sufficient enough to open the latch at the appropriate time, without releasing the fuel too early, as this would cause the reaction to accelerate and increase in violence rather than react at a constant rate; so limitations such as these could mean that the power output could not be readily scaled to any real extent. One could take steps to alter this reality by changing the amount of pressure applied by the piston to account for a lessening of pressure applied from the fusion reaction due to decreased power consumption.

The heat and power from the reaction could be harnessed in the same way or a similar way as is currently utilized to harness the power of traditional nuclear power.
