Tuesday, February 19: Radioactive Waste (PowerPoint) The spent fuel from the Naval Nuclear Storage waste was dumped directly into the sea. Waste has been stored in cracked concrete bunkers. There is a dilemma that there is no roadway or trains so they must use ships to travel. One of the economic issues is the transportation. 3 sites evaluated: - Deaf Smith County, Texas o Ogallala Aquifer - Hanford, Washington o Columbia River - Yucca Mountain, Nevada Facts to Support Yucca Mountain* - One of the most studied pieces of property in the world Video: Radioactive waste disposal: Tens of thousands of years Yucca Mountain, Nevada has been decided by the US to dispose radioactive waste. Low level waste is buried underground as little as 10 feet below the surface. High level waste, uranium, plutonium, and nuclear rods, have to be stored underwater which is moved by machines. The “repository system” is the system in which the high level waste will be stored in the Yucca Mountain. The Yucca Mountain Zeolites is a mineral found in the area. The mineral helps filter out the radioactive materials from waste. It was shown that if radioactive liquid was poured into Xeolites, the water that was filtered to the bottom was found to be significantly less in radioactive material. Packrats are the type of animals native to Yucca Mountain. They use all types of materials found in the mountain to build a nest. The nests are used to understand how the climate was long time ago. Then they can predict how it will be in the future. Thursday, Feb. 21: Climate Change Greenhouse Effect Slide* Greenhouse Gases: Carbon Dioxide and Methane are the main gasses Human Activities - Carbon Dioxide o Released when solid waste, fossil fuels (oil, natural gas & coal) and wood/wood products are burned. - Methane

Video: Too Hot NOT to Handle Main Concepts of the Consequences: - Heat Waves – Heat waves are the main number 1 killer in regards to natural disasters. o Green house effect: Sunlight and heat is trapped into the Earth’s Atmosphere. o Humans are adding extra green house gases by burning coal, fossil fuels, and most uses of energy. - Extreme Weather – Abnormal weather that is the cause of natural weather. o Heavy rains that cause massive floods, instead of moderate rain showers o In some areas the climate will become severely drier. Drought will be the main factor in these areas. - Water Supply – Climate changes will affect the snow and rain. o The snowpack will not accumulate in areas where it should be accumulating. The snowpack accounts for one of the main sources of clean drinking water. 75% of the water is from snowpack. - Forest Fires – Heat, drought, and dead trees are the main factors contributing to forest fires. -
