Assume the following: ●In a light water reactor, approximately 1.0kg of spent nuclear fuel is produced for every50. megawatt-days (MWd) of thermal energy input. ●For the purposes of this analysis, assume the spent nuclear fuel produced is 1.8% Pu-240by mass. Pu-240 has a half-life of 6,430 years. ●The thermal efficiency of the power plant is 38% ●Use equation for radioactive decay: Qt= Q0^e-kt where: ○Qt = quantity of radioactive material at time t ○Q0 = original quantity of radioactive material ○k = the decay constant ○t = time interval in years ○The decay constant k is defined by the relation: Half life = ln(2)/k Diablo Canyon stores 95% of its spent nuclear fuel onsite. ii) How many metric tons of Pu-240 in the spent fuel will still be onsite in that year?
