A nuclear reactor has been operating for one year at an average flux level of 1 x 10¹³ n/cm².s when the power level is reduced by 50%.

Write a computer code to plot the curve of xenon concentrations in the core for a period of 12 hours starting from the moment the reactor power is reduced. Use the equations given below as they are. The symbols denote the usual variables used in xenon and iodine poisons.

Your submission should include the values of all variables used, the computer code listing, the plots, and your comments on the curves.
