Suppose you are working as a reactor operator in the world’s largest nuclear power station at Kashiwazaki-Kariwa Nuclear Power Plant, Japan. The first unit in this station began to operate in 1985.
Suppose the rate at which the nuclear power plant produces radioactive waste is proportional to the number of years it has been operating such that 500 pounds of waste is produced every year. Also, suppose that the waste decays exponentially at a rate of 5% per year.
At the beginning of 2011, The Fukushima Daiichi nuclear disaster caused sever damages in the units which released the radiation waste to the atmosphere. Therefore, all the units were closed in 2011 for safety inspection. This left japan completely without nuclear-produced electrical power. Finally, the unit began to operate at the beginning of 2019. As a reactor operator, you are asked to do the following:
a. Model the generation of the Kashiwazaki-Kariwa Nuclear Power Plant radioactive waste as a function of time.
b.…
Carbon-14 is an isotope of carbon that is formed when radiation from the sun strikes
ordinary carbon dioxide in the atmosphere. Plants such as trees, which get their carbon
dioxide from the atmosphere, therefore contain a small amount of carbon-14. Once a
particular part of a plant has been formed, no more new carbon 14 is taken in. The carbon
14 in that part of the plant decays slowly.
Let P be the percent of carbon-14 remaining in a part of a tree that grew t years ago (so t
years ago, there was 100 percent of the carbon-14 existing in that part of the tree).
Write the particular equation expressing P in terms of t. You may assume that the half-life
of carbon-14 is 5730 years.
a.)
A piece of wood some believe to have come from Noah's Ark has 47.93% of its carbon-14
remaining. The Great Flood was supposed to have occurred in 4004 B.C. Is this piece of
wood old enough to have come from Noah's Ark? Justify your answer.
b.)
A radioactive element has a half-life of 3 days. The initial amount
of that element is 1024 grams. How many grams of that element
are left 12 days later? Write down your answer as an integer
value (no decimals) and do not write the unit.
