Trapping Carbon Dioxide Or Switching To Nuclear Power Not Enough To Solve Global Warming Problem, Experts Say
Trapping Carbon Dioxide Or Switching To Nuclear Power Not Enough To Solve Global Warming Problem, Experts Say
Science Daily (July 14, 2009) — Attempting to tackle climate change by trapping carbon dioxide or switching to nuclear power will not solve the problem of global warming, according to energy calculations published in the July issue of the International Journal of Global Warming………………………….
Their calculations suggest that most measures to combat global warming, such as reducing our reliance on burning fossil fuels and switching to renewables like wind power and solar energy, will ultimately help in preventing catastrophic climate change in the long term. But the same calculations also show that trapping carbon dioxide, so-called carbon dioxide sequestration, and storing it deep underground or on the sea floor will have very little effect on global warming.
“Since net heat emissions accounts for most of the global warming there is no or little reason for carbon dioxide sequestration,” Nordell explains, “The increasing carbon dioxide emissions merely show how most net heat is produced……………………The researchers also point out a flaw in the nuclear energy argument. Although nuclear power does not produce carbon dioxide emissions in the same way as burning fossil fuels it does produce heat emissions equivalent to three times the energy of the electricity it generates and so contributes to global warming significantly, Nordell adds.

Nuclear power and water – theme for February 2012
FUKUSHIMA NUCLEAR PLANT and WATER – present state
That nuclear core is in direct contact with tons of water. And that containment, while not leaking down, is leaking out the sides. That contaminated water is going into every other building on site. And there is literally thousands and thousands of tons of water in other buildings. That water contains radioactive cesium, radioactive strontium, and it also contains nuclear fuel. There will be uranium in that water and plutonium in that water as well. We know for sure that that water is leaking into the ground water and into the Pacific Ocean. So while it is important to know that we are not going to release the nuclear core directly into the center of the earth, the problem is not over. And as a matter of fact, the problem will last for tens, perhaps even as long as 30 years because this contaminated water is in the basements of all the buildings on site. And not only does it contain cesium (that hangs around for 300 years), strontium (hangs around for 300 years), but it also contains plutonium and uranium and they have half lives of tens of thousands of years.
So the problem is, what do we do with all that water that is contaminated? It is already leaking into the groundwater. It is already leaking into the ocean. TEPCO is frantically catching it and putting it into tanks. But just today, TEPCO announced that they are running out of tank space on site, and eventually they are going to have to release those tanks into the Pacific Ocean. Now they will try to clean up some of the isotopes like cesium. But they have been unable to capture all the strontium. Strontium is a bone seeker that causes leukemia… http://fairewinds.com/content/fukushima-could-it-have-china-syndrome
NUCLEAR REACTORS - WATER USE : Per megawatt existing nuclear power stations use and consume more water than power stations using other fuel sources. Depending on the cooling technology utilised, the water requirements for a nuclear power station can vary between 20 to 83 per cent more than for other power stations.”- Dep of Parliamentary Services research note, 4 December 2006, no. 12, 2006–07, ISSN 1449-8456 Water consumption figures:
Nuclear: 2.3 L/ kWh
Solar (PV): 0.110 L/ kWh
Wind: 0.004 L/ kWh
(American Wind Energy Association estimate & US DOE)
A typical 1000-megawatt pressurized-water reactor (with a cooling tower) takes in 20,000 gallons of river, lake or ocean water per minute for cooling, circulates it through a 50-mile maze of pipes, returns 5,000 gallons per minute to the same body of water, and releases the remainder to the atmosphere as vapor. A 1000-megawatt reactor without a cooling tower takes in even more water–as much as one-half million gallons per minute. The discharge water is contaminated with radioactive elements in amounts that are not precisely known or knowable, but are biologically active.
Some radioactive fission gases, stripped from the reactor cooling water, are contained in decay tanks for days before being released into the atmosphere through filtered rooftop vents. Some gases leak into the power plant buildings’ interiors and are released during periodic “purges” and “ventings.” These airborne gases contaminate not only the air, but also soil and water. http://www.nirs.org/factsheets/routineradioactivereleases.htm
NUCLEAR REACTORS -IONISING RADIATION to GROUNDWATER In USA the nuclear industry has contaminated groundwater with radioactive tritium at nuclear power plant sites all across the country. Nuclear plants that have admitted leaking tritium into the groundwater include:
- Braidwood, Byron, Dresden and Quad Cities in Illinois;
- Indian Point and Fitzpatrick in New York;
- Yankee Rowe and Pilgrim in Massachusetts;
- Three Mile Island and Peach Bottom in Pennsylvania;
- Callaway in Missouri
- Catawba in South Carolina
- Oyster Creek in New Jersey
- Hatch in Georgia
- Palo Verde In Arizona
- Perry in Ohio
- Palisades in Michigan
- Point Beach in Wisconsin
- Salem in Delaware
- San Onofre in California
- Seabrook in New Hampshire
- Shearon Harris in North Carolina
- Watts Bar in Tennessee
- Wolf Creek in Kansas
- Connecticut Yankee in Connecticut
- Vermont Yankee in Vermont
URANIUM MINING – OPEN CUT or UNDERGROUND It is very difficult to find figures on the amounts of water used. All mining is water intensive, but uranium mining is the greatest guzzler Water is extensively used to suppress airborne dust levels, to try to reduce the radioactive clouds that would otherwise emanate constantly from the uranium tailings.IN SITU LEACHING – Uranium Mining Process in-situ leaching uses a hydrogen peroxide mixture to strip the uranium from the rock, which kills tissue and destroys cells in human and animal life. The addition of oxygen and sodium bicarbonate called oxygenates causes uranium and other radioactive substances and trace metals to be liberated from the rock into the groundwater.
.. judges have too often taken the stance that they are judges who know nothing of the mining industry and accept the data of corporations, claiming the corporations are in the know.
..the water taken from the extremely pristine Westwater Canyon Aquifer near Crownpoint for uranium mining and used for flushing out chemicals would not be replaced in our lifetimes.
It takes hundreds, perhaps thousands of years, to transform aquifer water back into a drinkable condition. Virginia Against Uranium Mining: Scientists Back Navajos’ Uranium Mining Fight: Tribe fears contamination of drinking water
