Determination of critical assembly absolute power using post-irradiation activation measurement of week-lived fission products

Popis výsledku v původním jazyce

The work presents a detailed comparison of calculated and experimentally determined net peak areas of longer-living fission products after 100 h irradiation on a reactor with power of similar to 630 W and several days cooling. Specifically the nuclides studied are Ba-140, (RU)-R-103, I-131, Ce-141, Zr-95. The good agreement between the calculated and measured net peak areas, which is better than in determination using short lived Sr-92, is reported. The experiment was conducted on the VVER-1000 mock-upinstalled on the LR-0 reactor. The Monte Carlo approach has been used for calculations. The influence of different data libraries on results of calculation is discussed as well.
