Let All Men Say… “THIS WAS ENGLAND’S
FINEST HOUR!!”
So What Will Others Say About Nuclear Power… After Fukushima?
Recall some Headlines… Reactor Adds to Horror Threat of Meltdown Rocks Japan Japan’s Misery Mounts Americans Leaving Japan New Fears in Tokyo as Radiation Level Spiked Tap Water Setbacks Mount at Leaking Nuclear Plant High Radiation Outside Japan’s Exclusion Zone EPA Finds Radioactivity in Richland’s Water
About Fukushima… I believe we will eventually be able to say…
THIS WAS NUCLEAR POWER’S FINEST HOUR!
What Really Happened? • The Fukushima nuclear facilities were damaged in a magnitude 9.0 earthquake on March 11, 2011 Plant designed for magnitude 8.2 earthquake. An 9.0 magnitude quake is over 7 times in greater in magnitude. • Serious secondary effects followed after being hit by a 14 meter tsunami.
Review of Accident • Reactors survived the massive earthquake!
• Tsunami hit an hour later and wiped out the diesel generators’ heat sink • No cooling capability for a considerable time • Increasing pressure from released hydrogen gas inside containment caused some venting to outer building • A hydrogen explosion took the roof and sides off the outer building • Containment stayed in-tact.
But What About Radiation? • Can’t See It • Can’t Touch It • Can’t Smell It •…IT MUST BE BAD!!

Above 1 Sv 100 mSv
Perspective • Number of fatalities caused by the earthquake/tsunami = > 15,000 • • • •
Number of fatalities caused by excess radiation = zero Number of injuries caused by radiation sickness = zero Number of latent cancers expected from excess radiation = zero Number of news stories hyping the “dangers” of radiation = Thousands!
Lessons to be learned: • The reactors survived the massive earthquake • The tsunami is the issue—NOT radiation • Design for huge tsunamis
Nuclear Attributes (Fundamental Properties) •
Energy Density - 1 million times fossil fuel - even higher for solar/wind
• Long Term Supply (several millennia) • No atmospheric pollutants during normal operation
Main Global Drivers for Nuclear Expansion • Need for Stable, Long-Term Supplies of Electricity • Energy security – geopolitical
• Carbon Emission Concerns

Implications of the Near Halt in Construction of New U.S. Nuclear Power Plants in Last Couple Decades
• Key Professionals Retired or Lost to Industry • Few Professionals Coming into the Industry • Manufacturing Plants Shut Down •Hence, New Construction Cost Much Higher in the Renaissance that began about 5 years ago
Utilities now “bet the farm” on new, large plants
Hence, the Principal Drivers for Small Modular Reactors • Reduced capital costs per plant • Meet electrical growth incrementally • Shorter construction schedules (modular construction) • Enhanced safety and security (some Fukushima influence) • Improved quality (in-factory construction) • Replace aging coal plants • Re-establish U.S. leadership (largely lost during last two decades)
• Create good domestic jobs • Serve international markets (with limited electrical infrastructure)

AGRICULTURE • Optimizing Water and Fertilizer Use • Speed Breeding of Improved Crops – Greater yield – Increased disease resistance – Better nutritional value
• Improved Animal Production – Increase body weight – Vaccines to eliminate diseases
• Insect Control
– Sterilization (screw worm, Mediterranean fruit flies, gypsy moths)
• Improved Food Safety (Food Irradiation)
– Kill bacteria, molds, yeasts, parasites, insects – Extend shelf life
Optimizing Water & Fertilizer Use • Higher Crop Production – Fertilizer: • Label (tracer property) to determine optimal effectiveness • Minimize fertilizer needed
– Water: • Neutron moisture gauges to determine proton content (moisture)
• Speed Breeding of Improved Crops New Species: • Increased crop yields (reduced fertilizer use) • Better disease, pest, & draught resistance (less pesticides & water) • Enhanced maturing times (allows crop rotation) • Improved nutritional value • Improved quality • Improved processing quality • Enhanced customer acceptance – Color; flavor
> 30 nations have developed ~ 2250 new crop varieties (radiation used in 89% of these!)
• Improved Animal Production – Nutrition: • Labeling food with C-14 allows tracing specific food products throughout the digestive system • Example: Multi-nutrient lick block for buffalos in Indonesia – Increased weight gain at rate of 3 Kg/week – Reduced grass consumption by 80%
– Vaccinations: (radiation tracers) • Example: Rinderpest (“cattle plague”) – Millions of cattle have died in Africa – Disease now eradicated in 16 of 18 African countries
• Insect Control – Chemical Treatments: • Create environmental pollution • Toxic residues remain in food chain • Insects develop tolerance to insecticides – Requiring increasingly higher doses
– Sterile Insect Technique (SIT) • Produce or capture large numbers of insects and sterilize them • Release them into their native environment • No offspring! – Tsetse fly eradicated in parts of Africa (allowing human settlement) – Other examples: Mediterranean fruit fly, Mexican fruit fly, Boll Weevil
• Improved Food Safety – Magnitude of Problem • Infestation & spoilage prevents ~ 50% of food grown in many parts of the world to be wasted • Spoilage of sea food sometimes as high as 90% • In the United States every year – Over 76,000,000 cases of food poisoning – Over 325,000 hospitalizations – Over 5,000 deaths
– Historic Food Preservation Techniques • Sun drying Salting • Smoking Canning • Heating Freezing • Chemical treatments (e.g. methyl bromide)
• Food Irradiation – Beta particles or gamma rays will kill bacteria & pathogens by breaking DNA bonds • (particularly effective during reproductive cycle)
– Specific pathogens targeted include: • Salmonella • E-coli (0157:H7) • Listeria monocytogenes
– NOTE: Goal is not to totally eliminate contamination • Some pathogens necessary in body to stimulate immune system • ~5 orders of magnitude reduction generally sufficient
Application to Food Industries
• Hygienic production and safe distribution • Stable supply of agricultural commodities • Efficient and scientific quarantine measures

Compliments of Prof. Ilham Al-Qaradawi
Photon Beam Application at Loma Linda University Medical Center, California
• Researchers at CERN have found that the antiproton, can effectively treat cancer. • Antiprotons strip electrons off atoms in the cells, causing ionization and killing the cell they are in. • A proton beam could also be used for ionization but when antiproton beam eventually come to a stop at the focus, the annihilation of both particles will release a huge amount of energy (in the context of a single cell)....which is much more effective at killing selected cells than simple ionization. • Scientists estimate that routine clinical application of matterantimatter annihilation to cancer treatment should be a reality in 10-15 years.

Dating Archeological Events The physics of radioactive decay
Carbon-14 Dating: 50 to 50,000 years
C-12: C-13: C-14:
Present in Atmosphere 98.89 % 1.11 % 1 atom in one trillion!
Carbon-14 Dating Procedure • Living species maintain a constant ratio of C-14 to C-12 • But, when death occurs, there is no more intake of carbon: C-12 is stable C-14 decays with T1/2 of 5715 years • Hence, ratio of C-14 to C-12 diminishes with time • Measuring this ratio dates the time of death
NOTE: Now possible to measure 3 atoms of C-14 out of a total of 1016 carbon atoms!

Environmental Protection …..ENVIRONMENTAL POLLUTION….. Determine 1) Amounts and Locations of Pollution 2) Causes of Pollution 3) Proper Remedy
• Managing Fresh Water Resources – Preserving and Obtaining Potable Water Sources
• Guarding the Oceans – Coastal Zones and the Deep Seas
• Understanding Soil Erosion – Loss of topsoil and erosion of waterways
• Radiological Contamination – Weapons production and commercial power
• Polluting our Atmosphere – Brown Clouds and global climate change
• Energy & the Environment
Managing Fresh Water Resources • 1/5 of our global population (1.2 billion) lack safe and affordable drinking water • Global demands for fresh potable water is doubling every 21 years! • Renewable water supplies available per person are ½ that of 40 years ago • This will drop in half again in another 20 years • The demand for potable water is increasing double the rate of population increase.
Water Use • 70% of fresh water is used for agriculture – Neutron probes are used to determine the water available for root systems – Radioactive tracers are used to determine the amount of water and fertilizer actually needed – NOTE: Huge amounts of energy needed to produce fertilizer
Obtaining New Sources of Fresh Water
• 97 % of the water on the planet is seawater • Major population areas exist in coastal regions • Hence, desalinate: – Requires considerable energy for extraction of salt – Nuclear heating may be an answer • BN-350 in Kazakhstan produced 150 MWe and 1 million gallons of potable water/day • Kalpakkam system in India now produces 1 million gallons of potable water /day via nuclear power
Nuclear Desalination • Reverse osmosis – use electric pumps off-peak • Distillation - scope for cogeneration
GUARDING THE OCEANS • 70% of Earth’s surface is covered with salt water • Over half the world’s population lies along coastal zones • One billion people depend on fish as sole source of protein
Oceans worthy of environmental protection
80% of all marine pollution comes from the following: – sewage & industrial effluents – fertilizer runoff – heavy metals discharge – persistent organic pollutants
All detectable by radioisotopes
SOIL EROSION • Topsoil erosion can be devastating to farmers – (1000 tons of topsoil are lost every second over a global basis)
• How can we determine when it is lost and where it accumulates? – A) Satellite images – B) Mathematical formulas – C) Radioisotopes—mainly Cs-137 from the fallout of nuclear weapons testing • Spread relatively uniformly over the globe • Measure where activity is higher and where it is lower
RADIOLOGICAL CONTAMINATION U.S. Nuclear Weapons Production Hanford (Washington) and Savannah River (South Carolina) major weapons production sites • Hanford: reprocessing waste in huge underground tanks – Single shell (some have leaked and trace amounts of radiation have been detected in the Columbia River) – Double shell tanks – Huge vitrification plant now well under construction Hanford Savanna River
RADIOLOGICAL CONTAMINATION Russian Nuclear Weapons Production • Raw nuclear wastes dumped directly into the Techa River and Karachai Lake • 1057 Myak Site: Dehydrated radioactive waste tank exploded • 1987 Chernobyl Accident – but actual hazards considerably less than at nuclear weapons sites
• Sunken Nuclear Submarines in Kara and Barent Sea – But sudies indicate very little radiation contamination
