In 1979 at Three Mile Island nuclear power plant in USA a cooling malfunction caused part of the core to melt in the second reactor. The TMI-2 reactor was destroyed. Some radioactive gas was released a couple of days after the accident, but not enough to cause any dose above background levels to local residents. There were no injuries or adverse health effects from the Three Mile Island accident.

The Three Mile Island power station is near Harrisburg, Pennsylvania in USA. It had two pressurized water reactors. One PWR was of 800 MWe (775 MWe net) and entered service in 1974. It remains one of the best-performing units in USA. Unit 2 was of 906 MWe (880 MWe net) and almost brand new.

(suggestion,if possible)Need to post information regarding what's the cause the cooling tower to malfunction. would be helpful.thanks.
ReplyDeletemeor: Sure, we are currently working on that. Thank you for your support and feedback.
ReplyDeleteGood, respond to your comments.
ReplyDeleteDisaster in power plant is a seriously especially when it's comes to human lifeHpw can we avoid these problems in future,especially in Malaysisa when we owe a nuclear power plant soon in future?

Glad to know that no life is lost in 3 miles island incident, it gives more assuarance and confidence in going nuclear.

If the water stops flowing, there is a problem. The core overheats and more of the water turns to steam.
ReplyDeleteThe steam generates huge pressures inside the reactor vessel - a big, sealed container - and if the largely metal core gets too hot, it will just melt, with some components perhaps catching fire.
