Description
The current status of our knowledge of fission-product yields and cross-sections is outlined and the data now in use at Chalk River is given. This data has been incorporated into a computer programme (FISSPROD) which takes account of accumulation of radioactive nuclides with half-lives > 5 h, and changes in flux, the epithermal component and reactor temperature. Computer results are used to demonstrate the effect on reactivity of uncertainties in the basic nuclear data. The fission-product absorption in 233U, 235U and 239Pu has recently been determined from reactor oscillator measurements of samples irradiated to 2-3 n/kb (AECL 2510). The results are compared to FISSPROD calculations and the significance of the differences is discussed. (author)
