<h3>What is a nuclear power plant?</h3>
A nuclear power plant is a plant that produces energy by the use of nuclear energy. In a nuclear plant we always have a nuclear fuel that is used in the plant. The fuel undergoes a fission reaction that enables the plant to be used for the production of electricity.
Now we know that a nuclear reaction is a case of exponential decay hence the y-intercept for this function is the decay constant of the function.
The time when the area will be safe again in the year 2086 because following the function;
f(x)=1000(0.5)^x/30 thus;
1000(0.5)^100/30
= 99.2 Kg
