Kärnkraftsolyckan i Japan

Det är ofta dumt att som lekman försöka sig på att skriva om det som professionella ägnat sitt liv åt att lära sig om. Det kan då vara bättre att referera till de som kan. Jag läste ett verkligen intressant blogginlägg av en som faktiskt kan igår, som handlade om kärnkraftsolyckan i Japan. Den som vill läsa den i helformat (det tar sin stund..) kan göra det här: länk.

Här kommer dock några citat ur texten (observera att det är han som har skrivit dem och som står för att de är sanna):

Up front, the situation is serious, but under control. ... you will know more about nuclear power plants after reading it than all journalists on this planet put together.

There was and will *not* be any significant release of radioactivity. By “significant” I mean a level of radiation of more than what you would receive on – say – a long distance flight, or drinking a glass of beer that comes from certain areas with high levels of natural background radiation.

There has not been one single (!) report that was accurate and free of errors ... By “not free of errors” I mean blatant errors regarding physics and natural law, as well as gross misinterpretation of facts, due to an obvious lack of fundamental and basic understanding of the way nuclear reactors are build and operated. I have read a 3 page report on CNN where every single paragraph contained an error.

I believe the most significant problem will be a prolonged power shortage. 11 of Japan’s 55 nuclear reactors in different plants were shut down and will have to be inspected, directly reducing the nation’s nuclear power generating capacity by 20%, with nuclear power accounting for about 30% of the national total power generation capacity. I have not looked into possible consequences for other nuclear plants not directly affected. This will probably be covered by running gas power plants that are usually only used for peak loads to cover some of the base load as well.  I am not familiar with Japan’s energy supply chain for oil, gas and coal, and what damage the harbors, refinery, storage and transportation networks have suffered, as well as damage to the national distribution grid. All of that will increase your electricity bill, as well as lead to power shortages during peak demand and reconstruction efforts, in Japan.

Jag tycker nog att alla kunde ta och lägga tid på att läsa det där inlägget ändå.
