Alternatively, they suggest that one should analyze the growth empirics country-by-country, rather than putting all countries under a cross-section setting.
In the early stages of shield design for the 500 MWe pool type Prototype Fast Breeder Reactor PFBRR), the DLC-37 coupled (100n, 21 γ) cross section set, extended to include data for the plutonium isotopes, only was used for the transport calculations.
Studies in this direction are now ongoing, providing, for the moment, a partial confirmation of the validity of the cross section sets used in TRAX (Hespeels et al. 2017).
Many 2-D R-Z transport calculations were carried out for FBTR including all regions of interest like borated graphite and carbon steel in the top shield and vault concrete to obtain 175 group neutron flux distribution in Vitamin J structure with IGC-S3 self shielded cross-section set.
The longitudinal direction of the TPM is set as x-axis, outer normal direction of cross section is set as y-axis and vertical downward direction is set as z-axis which is selected as force hammer stimulating direction.
An analysis is performed to determine the size of the temperature intervals for custom-developed cross-section sets, which indicated the necessity of 50 K bins in the fuel and 10 K bins in the coolant.
Accurate modeling of the reactor physics in a SCWR requires a detailed temperature treatment, including the effects of Doppler broadening (TMP cards in MCNP), thermal scattering (MT cards), and fully temperature-dependent cross-section sets for fuel and coolant (using the MAKXSF code).
This work provides the first cross section data set of DNA constituents for an impact of electrons in the energy range between about 10 eV and 1 keV on a DNA target.
To approximate a semi-infinite medium the slab cross section was set to 10 x 10 cm.
In addition, to approximate a semi-infinite medium the medium cross section was set to 10 x 10 cm.
Both studies, however, rely on cross-sectional data only – with Hirsch et al. ([2012]) utilising the 2008 cross section of the data set used in this study.
