Biggest Commercial Nuclear Disaster of USA😨. See👇the description.

---------------------------------------------------------

On 28th March 1979, at 4:00 AM in Morning,

Reactor no. 2 of Nuclear power plant of Three Mile Island, Londonderry Township, Douphin County, Pennsylvania near Harrisburg,
Colling system of Reactor malfunctioned,
The reactor shut down immediately but as pressure built from extra heat🔥 of Nuclear fuel,
A relief valve was opened but mechanical fault in valve cause it to Fail to close it again after reaching controlling pressure.

This results into draining of so much of Coolant water that,
Emergency pump had to add extra cooling water.

Engineers were unaware that more water was needed due to opened valve which was draining water continuously and boiling it away out of reactor.

The core of Reactor was exposed to Intense heat🔥 and it was damaged severely resulting in Partial meltdown of Reactor.

Radioactive ☢️material entered in water💦 and water was turned into Steam💨 resulting in release of Radioactive☢️ material into surrounding atmosphere😨.

But by this Evening, Engineers were successful in managing to reduce the temperature 🌡️of Core of Reactor thus avoiding a Total Meltdown of it.

But announcement of presence of Explosive hydrogen in reactor which can cause even more dangerous situation, lacs of people started migrating from that place but they made comeback after the assurance from the Government.

Also they were not any harmful effects of Radiation founded in any person.
