Three Mile Island accident

The Three Mile Island accident was a nuclear meltdown that occurred on March 28, 1979, in reactor number 2 of Three Mile Island Nuclear Generating Station (TMI-2) in Dauphin County, Pennsylvania, United States. It was the worst accident in U.S. commercial nuclear power plant history. The incident was rated a five on the seven-point International Nuclear Event Scale: Accident With Wider Consequences.

The accident began with failures in the non-nuclear secondary system, followed by a stuck-open pilot-operated relief valve in the primary system, which allowed large amounts of nuclear reactor coolant to escape. The mechanical failures were compounded by the initial failure of plant operators to recognize the situation as a loss-of-coolant accident due to inadequate training and human factors, such as human-computer interaction design oversights relating to ambiguous control room indicators in the power plant's user interface. In particular, a hidden indicator light led to an operator manually overriding the automatic emergency cooling system of the reactor because the operator mistakenly believed that there was too much coolant water present in the reactor and causing the steam pressure release.

Sam & Mark's TMi Friday

Sam & Mark's TMi Friday (originally TMi) is a British children's entertainment programme that was produced for five series by the BBC and aired from 16 September 2006 to 17 December 2010.

Format

TMi launched on 16 September 2006 as a Saturday morning show, airing in the autumn/winter months on BBC Two, replacing former occupant Dick and Dom in da Bungalow. Former Pop Idol contestants turned presenters Sam Nixon and Mark Rhodes, better known as Sam & Mark, were joined by Caroline Flack for a mix of cartoons, competitions, games, music videos and celebrity guests. The first series had a reality theme to the proceedings, which had never been done before on a children's Saturday morning show. This consisted of Sam and Mark living in the 'TMi flat' throughout the week, mainly rehearsing or practicing for their weekly head to head challenges in the studio. In 2007, it had been reported that TMi had used a fake phone-in caller during the game, Birthday Bingo, on the first show.
