Former Approach for FP Release Calculation<br />
• FRESCO-II: Fission product release calculation for one or<br />
several representative fuel element(s)<br />
• Time averaged release rate of sphere is multiplied with <strong>the</strong><br />
<strong>to</strong>tal number of fuel elements <strong>to</strong> determine core release rate<br />
„x“ cor re passes<br />
‣ Conservative approach<br />
‣ No spatial distribution of fission product release<br />
‣ More detailed calculation method necessary<br />
