Three mile island nuclear power plant

America’s worst accident at a civilian nuclear power plant occurred on March 28, 1979, at Three Mile Island. Operators were trying to repair a problem with piping in the water circulation system, and they accidentally blocked the flow of water. This stopped the removal of heat from the reactor, and began a series of events that would change the way America thought about nuclear power.

Within ten seconds after the flow of water was blocked, the reactor vessel became hotter and the pressure rose. Safety control rods were automatically thrust down into the reactor, causing the chain reaction to stop completely. Pressure, however, continued to build. A relief valve opened but failed to close. As a result, too much water escaped, and the reactor began to melt down.

[1] Large quantities of radioactivity began to leak from the reactor. [2] Most of the radioactivity was contained, and it is likely that no one received a harmful amount of radiation. [3] “Three Mile Island” became the reason that many Americans are afraid of nuclear power to this day. [4]

Where did the first problem occur at Three Mile Island?

Stellar Astronomy

Many parameters are used to describe a star. One of them is its temperature, which can be determined by simple observation; the color of a star and its temperature are related. Once the color of a star is identified, its temperature can be calculated through the use of scientific principles such as Wien’s Law.

There are different types of stars in the universe. For our purposes, we can classify them into two categories: variable and binary. Variable stars are those which show some degree of variability in their luminosity and magnitude. Luminosity refers to the amount of energy radiated by a star, while magnitude refers to its brightness. At time the degree of variability may be high, requiring a telescope with an equally high light- gathering power. This can be achieved by using a lens of large diameter, such as that of a reflecting telescope.

Binary stars are those found in pairs that revolve around a common center. The closest star to the sun, Proxima Centauri, is a binary star. To observe a binary star, the resolving power of a telescope - its ability to distinguish between two close objects having a small angular separation - must be very high.

Stellar astronomy is possible for a everyone, well beyond mere looking at the sky with the naked eye in order to identify constellations. With two basic of telescopes and rudimentary knowledge, much exploration can be achieved.

Binary stars are those found in pairs that revolve around a common center. The closest star to the sun, Proxima Centauri, is a binary star. To observe a binary star, the resolving power of a telescope - its ability to distinguish between two close objects having a small angular separation - must be very high.

Stellar astronomy is possible for a everyone, well beyond mere looking at the sky with the naked eye in order to identify constellations. With two basic of telescopes and rudimentary knowledge, much exploration can be achieved.

Stellar Astronomy

Many parameters are used to describe a star. One of them is its temperature, which can be determined by simple observation; the color of a star and its temperature are related. Once the color of a star is identified, its temperature can be calculated through the use of scientific principles such as Wien’s Law.

There are different types of stars in the universe. For our purposes, we can classify them into two categories: variable and binary. Variable stars are those which show some degree of variability in their luminosity and magnitude. Luminosity refers to the amount of energy radiated by a star, while magnitude refers to its brightness. At time the degree of variability may be high, requiring a telescope with an equally high light- gathering power. This can be achieved by using a lens of large diameter, such as that of a reflecting telescope.

Binary stars are those found in pairs that revolve around a common center. The closest star to the sun, Proxima Centauri, is a binary star. To observe a binary star, the resolving power of a telescope - its ability to distinguish between two close objects having a small angular separation - must be very high.
