WEC energy consumption doubled by 2050
World will turn to Fission Energy
Produces very small amount of spent fuel
6yrs of operation, 4-meter cube
Recyclable

6. Fusion: Overview and History
British Physicists in the 1940s and 50s housed in a hangar at Harwell a device called ZETA - Zero Energy Toroidal Assembly which was the first fusion based operating system.
Masked in the secrecy of the Cold War
Fusion is the production of a thermonuclear reaction in a gas discharge
Called 'fusion' because it is based on fusing light nuclei such as hydrogen isotopes
to release energy, similar to that which powers the sun and other stars.

7. The Process
Nuclei of two isotopes of hydrogen, deuterium (D) and tritium (T) react to produce a helium (He) nucleus and a neutron (n). In each reaction, 17.6 MeV of energy (2.8 pJ) is liberated:
D   +   T     4He (3.5 MeV)   +   n (14.1 MeV)

8. Fast Facts A vast, new source of energy. Fuels are plentiful.
Inherently safe since any malfunction results in a rapid shutdown.
No atmospheric pollution leading to acid rain or "greenhouse" effect.
Radioactivity of the reactor structure, caused by the neutrons, decays rapidly and can be minimized by careful selection of low-activation materials. Provision for geological time-span disposal is not needed.
Sunlight is energy released from fusion reactions in the sun.
Complete fusion reactions produce no long-life products
The fusion bomb, developed and first exploded in the early 1950's, was the first use of nuclear fusion.

9. The Future is Fusion
The Sun is our Greatest source of energy…the sun uses fusion
The source of fusion is vastly abundant in our oceans (an isotope of hydrogen in water)
The waste of fusion is helium, and there is no pollution of long term extent.
The price of fusion is estimated to be equivalent to that of fossil fuels
Fusion can give us energy for millions of years

10. Nuclear Waste - Two types of nuclear waste o Low level o High level
Two types of high level wastes
+ Spent
+ Waste materials
-         Storage Methods
+ Pools
+ Above ground storage casts
-    Transportation of Spent nuclear Fuel
+ Shipped throughout the US to storage facilities

11. Fission Versus Fusion
European Safety and Environmental Assessment of Fusion Power (SEAFP) team in The main participants in SEAFP were the NET (Next Experimental Torus) team, the UKAEA , established Fusion as a “very clean and environmentally friendly source of energy for the future with very good inherent safety qualities; there are no chain reactions and no production of 'actinides‘.”
The only waste products are helium, and toxic waste that is contained within the chamber and is not long-term.
Fusion produces no climate-changing or atmosphere-polluting emissions.
With Fission, relatively low environmental issues when costs are paid to maintain an environmentally friendly work area, however these costs are so high that it would be a problem in second and third world countries. There is also the problem in the case of a malfunction, worst case scenario can be very severe as opposed to the shut down process of fusion.
