Play #1 New York Times Bestseller Over 10 million copies sold In this generation-defining self-help guide, a superstar blogger cuts through the crap to show us how to stop trying to be "positive" all the time so that we can truly become better, happier people. For decades, we’ve been told that positive thinking is the key to a happy, rich life. "F**k positivity," Mark Manson says. "Let’s be honest, shit is f**ked and we have to live with it." Manson makes the argument, backed both by academic research and well-timed poop jokes, that improving our lives hinges not on our ability to turn lemons into lemonade, but on learning to stomach lemons better. There are only so many things we can give a f**k about so we need to figure out which ones really matter, Manson makes clear.

Three Mile Island | Nuclear Reaction | FRONTLINE On March 28, 1979 Reactor 2 at the Three Mile Island nuclear power plant suffered a partial meltdown. Within weeks attorneys filed a class action suit against Metropolitan Edison Company (a subsidiary of General Public Utilities) on behalf of all businesses and residents within 25 miles of the plant. Over 2,000 personal injury claims were filed, with plaintiffs claiming a variety of health injuries caused by gamma radiation exposure. The Pennsylvania district court quickly consolidated the claims into ten test cases. Over the next 15 years, the case went to the Supreme Court and back, and through various district and appeals courts. Finally, in June 1996 district court judge Sylvia Rambo dismissed the lawsuit granting summary judgment in favor of the defendants. What follows is an excerpt from the official court summary covering Judge Rambo's decisions on the key questions: 1) "Were Plaintiffs Exposed to Radiation Released From TMI during the TMI Accident?" C. Rogovin Report at 3-4. D. 2.

Backgrounder on the Three Mile Island Accident Printable Version (does not include Animated Diagram of the Sequence of Events)Three Mile Island History (Video) On this page: The Three Mile Island Unit 2 (TMI-2) reactor, near Middletown, Pa., partially melted down on March 28, 1979. This was the most serious accident in U.S. commercial nuclear power plant operating history, although its small radioactive releases had no detectable health effects on plant workers or the public. Its aftermath brought about sweeping changes involving emergency response planning, reactor operator training, human factors engineering, radiation protection, and many other areas of nuclear power plant operations. It also caused the NRC to tighten and heighten its regulatory oversight. A combination of equipment malfunctions, design-related problems and worker errors led to TMI-2's partial meltdown and very small off-site releases of radioactivity.

Three Mile Island - 25 Years Later On March 28, 1979, America experienced its worst nuclear accident - a partial meltdown of the reactor core at the Three Mile Island nuclear power plant near Middletown, Pennsylvania. During the tension-packed week that followed, sketchy reports and conflicting information led to panic, and more than one hundred thousand residents, mostly children and pregnant women, fled the area. Early on the morning of March 28, several water-coolant pumps failed on the second reactor at Three Mile Island (TMI-2), causing the reactor to overheat. The reactor shut itself down eight seconds later, but the core temperature continued to rise because valves controlling the emergency cooling water were stuck closed. Sixteen hours later, the core was finally flooded and its temperature brought under control. By this time, half of the core had melted, and part of it had disintegrated, although it was years before scientists actually discovered that a meltdown had occurred.

Three Mile Island | TMI 2 |Three Mile Island Accident. (March 2001, minor update Jan 2012) In 1979 at Three Mile Island nuclear power plant in USA a cooling malfunction caused part of the core to melt in the # 2 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. The accident to unit 2 happened at 4 am on 28 March 1979 when the reactor was operating at 97% power. The operators were unable to diagnose or respond properly to the unplanned automatic shutdown of the reactor. The chain of events during the Three Mile Island Accident Within seconds of the shutdown, the pilot-operated relief valve (PORV) on the reactor cooling system opened, as it was supposed to. Operators responded by reducing the flow of replacement water. The Hydrogen Bubble Summary

Three Mile Island Nuclear Power Plant Disaster & Others: Part 2 of A History of Nuclear Power Plant Disasters written by: Rose Kivi•edited by: Niki Fears•updated: 9/24/2010 This article is part two of a three part series that details some of the worst nuclear power plant accidents in history including the Three Mile Island Nuclear Power Plant, Windscale & Lubmin. Windscale Nuclear Power Plant - October 10, 1957An accident occurred at the Windscale Nuclear Power Plant in England that caused a radiation leak which spread 200 square miles. Faulty equipment at the plant gave inaccurate temperature readings.
