BURP2 calculates the activity of 237 radioactive fission products for up to 100 consecutive reactor operating and shutdown times. Fission products can be allowed to leak from the fuel at any specified rate. The activity of each nuclide is calculated in the fuel, coolant, and purification filter system. The total gamma-ray source strengths are calculated at each time step in the core, coolant, and purification filter system. For each time step, new values may be assigned to the reactor power, thermal neutron flux, fraction of the total fissions due to one or two fissioning isotopes, and the coolant and filter cleanup rates. The user must assign a filter purification efficiency, a fuel leak rate and a plate out rate for each fission product. Removal of fission products by neutron absorption is included in the fuel but not in the coolant or filter. The activated fission product is not returned to the fuel. Activation of structural materials is not considered. The user has the option of saving his data on tape for further processing.
