Nuclear Power for Thailand

The NGO's and others aren't to bear all the blame. The real damage was done by the big corp's, especially GE who wanted to build plants with fuel supply contracts folded in, and the wepons hawks who realized thorium tech wasn't good for making bombs. Long before there WAS a protest movement, the US was turned away from thorium in favor of the current technology. Thorium tech was already a proven technology, but the plug was pulled. If not for the corps and the military industrial complex, there would be no protest movement, or energy shortage, because we would all have had thorium plants for 50 years! The whole deal stinks.

Paul Garrioch wrote:The Prime Minister has explained the plan for a nuclear power plant to produce energy for Thailand and help Thailand move away from reliance on oil and gas. Thailand is a net importer of energy, getting much of its energy from the middle east at a huge cost to the country. Added to that the use of oil is polluting and a cause of green house gases.

So the plan is to import huge numbers of foreign experts into Thailand and spend lots of money to build a nuclear power plant which would be operational by about 2020. Thailand would then need to continue hiring foreigners to run the plant, perhaps continue paying off the foreign debt they will get by building the plant and will be in constant need of foreign uranium and foreign help to get rid of or store the incredibly toxic waste produce that comes from nuclear energy.

It seems to my simple brain that this does not fix Thailand's energy problems. Nuclear energy relies on foreign materials (uranium) which Australia almost has a monopoly on and so can set the price however they want (ie. wait 10-20 years until everyone relies on uranium and then double the price). Nuclear energy is just as polluting or more so than oil, especially if you count the mass usage of oil and coal used in the mining of uranium. Then there is the massive problem of storing incredibly toxic waste for thousands of years. Added to that - in a world political situation that is becoming more unstable and a world environment that is becoming more unstable - why would we want a nuclear power plant anywhere near us?

Hmmm, what can we do to stop this silly idea???? Clearly the better answers are:
Use less energy.
Use energy more efficiently
Use renewable energy sources such as solar, wind, thermal, tidal, etc.

It is absurd to continue to use massive amounts of energy when 50 years ago the energy consumption was less than 5% of what it is today. Nuclear is not the answer. Look at what happened in Japan. Nuclear plants are unsafe. Turn to renewable energy sources, such as solar, wind, and water.

Thai's can not even run a proper waste disposal system let alone a nuclear power plant.(the Russians, Japaness and American's have all had there problems) But if they do it will only be a matter of time ( I was asleep in my hamock, I was drunk it's Songkran) for there to be another enviromental disaster to contaminate this country.

Nuclear in Thailand? :o
Solar or wind is far cheaper and secure :P

To Thailand Minister Of Power

Why I like Geo Thermal and Makes me exited when I wake up each day.
Geothermal energy - natures heat from the earth - it is free and todays energy markets it beats the door down on environmental and economic advantage over fossil and nuclear energy sources.
Geo Thermal Heat from the earth can be used as the biggest energy source in the modern World, from large Offshore power stations to small and relatively simple pumping systems. My Panda 1 design for 2500MW or enough power for large city of 1 million homes.
This heat energy, geothermal renewable at source, can be found almost anywhere—as far away as remote deep wells in China and Indonesia and as close as the soil in our Garden.
Tapping geothermal energy is an affordable and sustainable solution to reducing our dependence on fossil fuels, and the global warming and public health risks that result from their use.
I wish that all Governments of this World would Try to take onboard for the benefits of the Country they serve and stride in new paths of Renewable HP Steam producing Generation investments.
Three different types of power plants - dry steam, flash, and binary - are used to generate electricity from geothermal energy, depending on temperature, depth, and quality of the water and steam in the area. In all cases the condensed steam and remaining geothermal fluid is injected back into the ground to pick up more heat. In some locations, the natural supply of water producing steam from the hot underground magma deposits has been exhausted and processed waste water is injected to replenish the supply. Most geothermal fields have more fluid recharge than heat, so re-injection can cool the resource, unless it is carefully managed.
Dry Steam Power
A dry steam power plant uses dry steam, typically above 235°C (455°F), to directly power its turbines. Dry steam is steam that contains no water droplets. All of the molecules are in a gaseous, as opposed to liquid, state. Dry steam plants are used where there is plenty of steam available that is not mixed with water. This is the oldest type of geothermal power plant and is still in use today. Dry steam plants are the simplest and most economical of geothermal plants. However, they emit small amounts of excess steam and gases. The geothermal plants at The Green land Geysers are dry steam plants.
Flash steam
Flash steam power use hot water above 182 °C (360 °F) from geothermal reservoirs. The high pressure underground keeps the water in the liquid state, although it is well above the boiling point of water at normal sea level atmospheric pressure. As the water is pumped from the reservoir to the power plant, the drop in pressure causes the water to convert, or "flash", into steam to power the turbine and or generators. Any water not flashed into steam is injected back into the reservoir for reuse. Flash steam plants, like dry steam plants, emit small amounts of gases and steam.
Flash steam plants are the most common type of geothermal power generation plants in operation today.

The water used in binary-cycle power plants is cooler than that of flash steam plants, from 107 to 182 °C (225-360 °F). The hot fluid from geothermal reservoirs is passed through a heat exchanger which transfers heat to a separate pipe containing fluids with a much lower boiling point. These fluids, usually Iso-butane or Iso-pentane, are vaporized to power the turbine. The advantage to binary-cycle power plants is their lower cost and increased efficiency. These plants also do not emit any excess gas and, because they use fluids with a lower boiling point than water, are able to utilize lower temperature reservoirs, which are much more common. Most geothermal power plants planned for construction are binary-cycle.
Main Advantages
Geothermal energy offers a number of advantages over traditional fossil fuel based sources. From an environmental standpoint, the energy harnessed is clean and safe for the surrounding environment. It is also sustainable because the hot water used in the geothermal process can be re-injected into the ground to produce more steam. In addition, geothermal power plants are unaffected by changing weather conditions. Geothermal power plants work continually, day and night, making them. a fantastic proposition to investors and from an economic view, geothermal energy is extremely price competitive in some areas and reduces reliance on fossil fuels and their inherent price unpredictability. It also offers a degree of scalability: a large geothermal plant can power entire cities while smaller power plants can supply more remote sites such as rural villages. The SPGAsia Concept is to use the old wellhead Platforms and Refurbish the old well bore hole with Heat resistance liner and introduce Topside Control in its Harness and Steam Process insure the safety of the sea water returns back to the Sea clean and Risk free.
Typical costs are 400M/700M for each Plant offshore

Thailand is in the unfortunate position to be increasingly hotter, and more humid, because of global warming.

Meaning - people will need increasing amounts of AC to live well. As I come from the country of Norway, which usually is cold, but sometimes is somewhat warm, I know a little about ACs, as we use them for pumping heat inside, to save electricity.

(1kW of electric power can move up to 4kW of heat, reducing energy consumption down to 1/4 with heat pumps)

Because our temperatures can go down to -20, even to -40 and lower in the winter, thus our building codes are very strict about insulation in the walls to keep the heat inside. In the summer, those who have heat pumps, can run them as regular
ACs, as a "bonus", as even 28-29 degrees celsius and strong sun can be hot for us farangs... :-)

However the insulation can work the other way around, to keep the heat _outside_!

I have never seen this way of saving energy being discussed anywhere, however insulating a house in a hot country, will save a lot of energy, because you will lessen the need for AC to keep the inside cold, _a lot_!

I notice that just one room in a typical two floor house in a gated community, meaning - house very nice after thai standard, needs one AC per room to keep cold.

And when you turn the AC off, the room will get warm in less than 10 minutes, because there is no insulation in the walls.

Eg. the temperature will rise from perhaps 24 to 30 degrees in just 10 minutes!

In Norway, say if the electric power goes out, and the house has no furnace or oil burner, only electric heating, and it is for example -10 celsius outside, it would probably take 4-5 hours before the 22 degree inside temperature drops about the same, about 6 degrees. With variations due to type of house, of course, condo vs big house, old house, new house etc.

Anyway, shorter power cuts are never a problem regarding the loss of heat inside, while here in Thailand, only a few minutes without power, and you will be sticky and hot! :-)

Typically only 1-2 heat pumps are enough to heat a large villa house in Norway, though some regular electric panel owens are used as backup, because the heat pumps will not work so well when the temperatures outside goes down to -20C typical in the coldest 1-2 months of the winter.

Meaning - if a house in Thailand or any other hot country was insulated as well as in Norway (10-15 cm of glass or stone wool inside the wall), only maybe one large AC, with help of a ventilation system, would be enough to cool down one house!

The windows obviously should be two or three layers insulating ones also, but that would depend on if you need to look outside
much or not, because insulating windows are very expencive, while stone wool is cheap, anyway some sort of film to reflect sunlight would be advisable, so the windows don't leak too much infraread radiation into the house.

If every house could use only one - 1 - AC instead of one per room, perhaps 4-5 ACs in a large family, it would mean a HUGE energy saving for not only Thailand, but any warm or hot country on the planet, and lessen the need for more power plants considerably, probably eliminate the need whatsoever!

(Additionally, scientists believe that the eruption of a supervulcano, is the less rarest of all threats towards the humanity, rarer than asteroids. Not unthinkable in a period of say, 100 years. Meaning, having a well insulated house, and an AC, which also can be made to work as a heat pump, will be helpful, if the temperature ever should happen to sink to low levels even in a hot country, until the atmosphere clear up again in a few years.)
