Department of nuclear engineering, university of california, berkeley. = n28: 28 m n49 (t) 49 m, t > 0, subject to n49 (0) = n49. Let n49(t) = n49, 1(t) + n49, 2(t). For each function, the following sub-problems are set: dn49 ,1(t ) dt dn49 ,2 (t ) dt. = n28: 28 m n49 (t ) 49,1 m, t > 0, subject to n49,1(0) = 0, and. = n49 (t) 49 m, t > 0, subject to n49, 2(0) = n 49. For n49, 1(t), the solution is n49,1(t) = for n49, 2(t), the solution is n49, 2(t) = n 49 (b) the burn-up is defined as. The number of fission pairs due to fissions in pu-239 is obtained by integrating n49(t) as. 49: denote the natural uranium mass per year as n, the depleted uranium mass per year as w, and the mass of enriched fuel as f. (a) 0. 2.
