Calculation <strong>of</strong> Fission Product Inven<strong>to</strong>ry<br />
• FRESCO-II:<br />
− Relative fission product release calculation with<br />
constant birth rate <strong>of</strong> fission product <strong>of</strong> interest<br />
− Neglecting space dependent neutron fluxes<br />
− Birth rate during accident is neglected<br />
• STACY:<br />
− Coupling <strong>of</strong> STACY with newly developed burnup<br />
code TNT<br />
− Including precise calculation <strong>of</strong> inven<strong>to</strong>ry in fission<br />
product release calculation<br />
− Still condensed birth and removal rate<br />
