Acriticality accident results in an experimental assembly temporarily having an effective multiplication factor (keff) of 1.035. if the assembly is producing 2 w of power at the start of the accident, what maximum power level is reached if the excursion lasts for 0.32 s before the device is rendered subcritical by disassembly? if the total number of fissions that occurred during this excursion is estimated at 4.2x10^15, what is the estimated total fission product activity one day after and 30 days after the accident?
