Abstract EN
To ensure that the outside dose rate of waste package is below the limitation of national laws and regulations, based on the standard 200L drum, a new drum with inner shielding was proposed for intermediate-level radioactive waste (ILW) storage.
For comparison, FLUKA and QAD-CGA were used to verify the shielding design of the ILW storage drums produced in INET with multiple inner shielding layers.
The flux and dose were calculated and analyzed for four different cases.
In QAD-CGA calculation, it was found that different buildup factors can lead to the considerably different results.
A weighted algorithm was proposed to correct QAD-CGA for multilayer shielding cases.
In FLUKA calculation, parameter optimization and tailored variance reduction technique (VRT) were used.
Quantitative efficiency evaluation of different FLUKA settings using the FOM factor was carried out.
The differences in the calculated dose rates results between the FLUKA and QAD-CGA programs are within one order of magnitude.
The results of QAD-CGA are generally higher than those of FLUKA.
The analysis shows that appropriate corrections in QAD-CGA can make the trend of the calculation results more consistent with the theory.
In FLUKA calculation, with optimized setting and VRT adopted, the calculation efficiency can be improved more than 20 times.
The results of this study provide not only suggestions for the design of the ILW storage drums but also useful references for other similar work.
