Transcript

  • 1. SOURCESHYDROELECTRIC WINDSOLAR
  • 2. FOSSIL FUELSCOAL PETROLEUM NATURAL GAS
  • 3. A pound is a pound. Or isit?THE COMBUSTION OF ONE POUND OFCOAL PRODUCES ONE KILOWATTHOUR OF ELECTRICAL ENERGY.IN COMPARISON, THE FISSION OF ONEPOUND OF URANIUM 235 PRODUCES 3MILLION KILOWATT HOURS OFELECTRICAL ENERGY.
  • 4. NUCLEARAdvantages: Relatively cheap to operate require relatively little fuel No pollutionDisadvantages: Expensive to build Waste Security
  • 5. We keep our fuel (solid uranium pellets) sealed inzirconium rods.
  • 6. Fuel Cells• 7 Trucks, each carrying 6 cases of 2-12 foot high fuel cells, can fuel 1000MW reactor for 1.5 years. (84 fuel cells)• To operate a coal plant of the same output and same timeframe would require 1 train of 89-100 ton coal cars EVERY DAY! This would produce 350,000 tons of ash and 4 million tons of CO & CO2.
  • 7. NUCLEAR REACTIONS
  • 8. A SUBSTANCE USED TO SLOW NEUTRONS FROM THEHIGH SPEEDS AT WHICH THEY ARE RELEASED IN FISSIONTO LOWER, MORE EFFICIENT SPEEDS WHICH INCREASETHE PROBABILITY OF CAUSING FISSION.

  • 10. COAL, NATURAL GAS, OIL,WOOD
  • 11. How it works
  • 12. Fun Radiation Facts!• The average person is exposed to 300 mrem/yr from natural sources and accepted risks (medical exams, flying)• Working in US nuclear power plants will typically yield an exposure of <100 mrem/yr (significantly less in US Navy reactors)• For comparison, a radiologist receives approximately 500 mrem/yr
  • 13. Fun Radiation Facts!• A person would get 1 mrem of exposure from: – Three days of living in Atlanta – Two days of living in Denver• The loss of life expectancy from 1 mrem is about 1.2 minutes. Compare that to: – One cigarette reduces life expectancy by 7 minutes
  • 14. Consequences of Radiation Exposure (if entire dose is received at once)• These are in REM! (1000 millirem) REM Effect – 0-25 No observable effect – 25-100 Slight blood changes – 100-200 Significant temporary reduction in blood platelets and white blood cells – 200-500 Severe blood damage, nausea, hair loss, hemorrhage, death in many cases – >600 Death in less than two months for over 80% of people
  • 15. BENEFITS Entry level bonus: up to $15,000 cash Advanced promotion to E-3 at sign onAdvancement to E-4 within 6-9 months ~90 American Council on Education (ACE)recommended college credits Re-enlistment bonus: up to $100,000 and firsttime advancement to E-5 Experience, leadership training, cross-training,secret clearance, specialized training Officer selection rates ~75%
  • 16. NUCLEAR AIRCRAFT CARRIER OVER 1300 FEET LONG 2-8 NUCLEAR REACTORS4000-7000 PEOPLE ONBOARD
  • 17. NUCLEAR FAST ATTACK SUBMARINE OVER 350 FEET LONGONE NUCLEAR REACTOR 135-150 PEOPLE
  • 18. SSBN •Survivable •Exact SSBN location known only to the crew •Two-Crew Concept • Blue and Gold crews • Totally separate commands • Alternating patrol cycle 68% Operational Availability ONE NUCLEAR REACTOR 150 – 175 PEOPLE ONBOARDCARRIES UP TO 24 TRIDENT C4 OR D5 ICBM’s
  • 19. •ex-USS DANIEL WEBSTER •ex-USS SAM RAYBURN (MTS 626) (MTS 635)
  • 20. • Two Land-based Prototypes in NY• Modified Advanced Reactor Facility (MARF)• S8G/Advanced Fleet Reactor (Trident SSBN)
