Table 7
Uncertainty analysis results of Zr95m0, Mo95m0, and Cs134m0.
| Fission products | Atomic density (atoms/barn·cm) | Fission yield uncertainty analysis results | Normal-based relative uncertainty (%) | Lognormal-based relative uncertainty (%) | Relative difference to lognormal-based relative uncertainty (%) |
| Zr95m0 | | 0.242 | 0.244 | −0.8 | Mo95m0 | | 0.456 | 0.458 | −0.4 | Cs134m0 | | 0.244 | 0.313 | −22.0 |
| Comment | These results show atomic densities in 9.8 kg heavy metal irradiated up to 90210.44 MW |
