Slide 1

Atomic Power Dennis Silverman, U C Irvine In the US, 20% of our power is created by atomic force. There are 103 US atomic force plants.

Slide 2

California related reactors Diablo Canyon, two reactors San Onofre, two reactors ⅓ of Palo Verde 1, 2, & 3 in Arizona

Slide 3

California Nuclear vitality Each of the five reactors produces around 1,100 million watts (megawatts) of power This is sufficient to power one million homes for each reactor Each reactor\'s generation is identical to 15 million barrels of oil or 3.5 million tons of coal a year. The aggregate 5,500 reactor created megawatts is out of a top state electrical force of 30,000 – 40,000 megawatts.

Slide 4

Worldwide Nuclear Power Reactors There are 440 atomic force reactors in 31 nations. 30 more are under development. They represent 16% of the world\'s power. They create a sum of 351 gigawatts (billion watts) of power.

Slide 5

World Nuclear Power Plants

Slide 6

Nuclear Electricity Production by Countries and Regions in Gigawatts (World Total 350 Gigawatts) and percent of power

Slide 7

How a Nuclear Reactor works 235 U splitting by retaining a neutron and creating 2 to 3 neutrons, which start by and large one more parting to make a controlled chain response Normal water is utilized as a mediator to moderate the neutrons since moderate neutrons take more time to go by a U core and have more opportunity to be ingested The protons in the hydrogen in the water have the same mass as the neutron and stop them by a billiard ball impact The additional neutrons are taken up by protons to frame deuterons 235 U is enhanced from its 0.7% in nature to around 3% to deliver the response, and is contained in bars in the water Boron control poles are embedded to assimilate neutrons when the time has come to close down the reactor The high temp water is bubbled or sent through a warmth exchanger to create steam. The steam then powers turbines.

Slide 8

Nucleons all the more firmly bound in Fission Product Nuclei – Gives 200 Mev Energy for each Fission

Slide 9

Nuclear Fission from Slow Neutrons and Water Moderator

Slide 10

Inside a Nuclear Reactor Steam outlet  Fuel Rods  Control Rods 

Energy Taken out by Steam Turbine

Slide 12

Production of Plutonium (Pu) in Nuclear Reactors 239 Pu is created in atomic reactors by the retention of a neutron on 238 U, trailed by two beta rots 239 Pu likewise partings by engrossing a warm neutron, and all things considered produces 1/3 of the vitality in a fuel cycle. 239 Pu is generally steady, with a half existence of 24 thousand years. It is utilized as a part of atomic weapons It can be reared for atomic reactors

Slide 13

Nuclear Weapons to Reactor Fuel We are purchasing very enhanced uranium (20% 235 U) from the previous Soviet Union\'s atomic weapons for a long time from 1993- - 2013 Converting it to low improved uranium (3% 235 U) for reactor fuel It will fulfill 9 years of US reactor fuel request It originates from 6,855 Soviet atomic warheads in this way

Slide 14

Nuclear Plant Future The nations of the world are every arranging their own particular course of atomic plant advancement or decay Nuclear force is focused with normal gas It is non-contaminating It doesn\'t add to an Earth-wide temperature boost Obtaining the fuel just takes 5% of the vitality yield Plant licenses have been reached out from 20 years to an extra 20 years

Slide 15

Nuclear Plant Future Newer outlines are being tried to make them more sparing and more secure Preapproval of a couple plans will hurry improvement Disposal of abnormal state radioactive waste as yet being concentrated, yet researchers trust profound internment would work Because they are have substantial electrical yield, their expense at $2 billion is difficult to get and ensure with banks Replacing plants might be less expensive utilizing the same destinations and control vessels

Slide 16

Nuclear Problems and Solutions Three Mile Island 1979 half center emergency, stuck valve with no pointer discharged water, however regulation vessel held More sensors included, better correspondence to specialists in Washington, don\'t kill crisis cooling 28 year US wellbeing record since mishap Chernobyl 1986 Human idiocy killed cooling framework Poor steam cooling reactor outline permitted insecure steam pocket to blast Graphite burst into flames Design not utilized as a part of different nations

Slide 17

Yucca Mountain Project: Nuclear Fuel and High Level Waste Repository Much more secure store than leaving abnormal state waste at 60 reactor locales around the nation. On old nuclear bomb testing base, inside a mountain. The capacity is over the water table. The Yucca Mountain site would be 60% filled by present waste. US has lawful duty to the reactor business. Site has been concentrated widely by researchers for more than 20 years. Will store waste amid its 10,000 year rot time. Inquiries of how to divert trickling water around and under the capacity vessels. Inquiries of radioactive rot debilitating capacity compartments. An answer would be to assemble compartments that can be opened and reincased, or to which encompassed housings could be included.

Slide 19

Liquid Metal Fast Breeder Reactor Uses the quick neutrons from 235 U parting on encompassing 238 U to deliver 239 Pu In 10-20 years, enough Pu is created to influence another reactor No mediators are permitted No water, must utilize fluid sodium coolant U must be at 15%-30% improvement to produce influence with quick neutrons while rearing Pu This is at weapons grade advancement, however Super-Phenix in France has worked for a long time

Slide 20

Nuclear Power Proposed Solution? Richard Garwin , MIT and industry propose: If a long time from now the world uses twice as much vitality, and half originates from atomic influence Need 4,000 atomic reactors, utilizing around a million tons of Uranium a year With higher cost physical metal, would keep going for a long time Breeder reactors making Plutonium could extend the supply to 200,000 years Nonpolluting, non-CO2 delivering source Need more prepared atomic specialists and destinations Study fuel reprocessing, waste transfer, and more secure plans. While atomic reactors must be on throughout the day and night, and force use is less around evening time, they could be utilized to energize electric autos. Until electric autos or a hydrogen era economy, they may just be utilized for the 40% of era utilized around evening time, up from the present 20% that they produce.

Slide 21

Fusion Reactors Fusion least demanding for Deuteron (D) + Tritium(T): D(p,n) + T(p,nn) → 4 He(pp,nn) + n in a high temperature plasma. Substitution T made from Li cover around reactor n + 6 Li → 4 He + T Fusion reactors International ITER in 2012 for exploration for 10 years, costing $5 billion Current stalemate over siting in France or Japan Followed by DEMO for a working plant, taking an additional 10 years. Outline and fruition of a business plant not until 2050. US Lithium supply would last a couple of hundred years. Still would be a radioactive waste transfer issue.

Slide 22
