It's not a nuclear explosion, but a steam explosion, caused by the huge buildup of pressure within the core. That blows the biological shield off the top of the core, ruptures the fuel channels and causes graphite to be blown into the air.

Why use 12 grams? This is the theoretical atomic mass of the Carbon-12 isotope (6 protons and 6 neutrons). This means that the atomic mass or atomic weight (12 grams) of carbon is equal to exactly 1 mole of carbon.

1 mole of carbon. Exactly 12 grams of pure carbon-12 powder is known as one mole. The number of atoms of carbon-12 present in this one mole sample is 6.022 136 7 x 1023. This number is known as Avogadro's number.

A series of graphite blocks surround, and hence separate, the pressure tubes. They act as a moderator to slow down the neutrons released during fission so that a continuous fission chain reaction can be maintained. Heat conduction between the blocks is enhanced by a mixture of helium and nitrogen gas.

So, the total amount of ATP burned to move 11.7 grams of muscle in the index finger is approximately 195 micromoles (11.7g×16.7μ mol/g). There are 7.3 calories in one mole of ATP energy, so the number of calories burned in clicking the mouse equals about 1.42 (7.3/1000) X 195)."

Melting ice at 0 degrees Celsius: It takes 80 calories to melt 1 gram of ice. If 1 g of ice (at 0 degrees Celsius) is given 80 calories, it will melt and the final temperature of the water will be 0.

A calorimeter is a device used to measure changes in thermal energy or heat transfer. If a reaction is carried out in the reaction vessel or if a measured mass of heated substance is placed in the water of the calorimeter, the change in the water temperature allows us to calculate the change in thermal energy.
