TSUNAMI-1D

The TSUNAMI-1D sequence computes the sensitivity of keff to cross-section data for systems that can be modeled in 1-D. The XSDRNPM module is used to produce forward and adjoint neutron transport solutions and the SAMS module is used to produce sensitivity coefficients. The BONAMIST and NITAWLST modules are used to produce the sensitivity of the resonance self-shielded multigroup cross-section data to input data for the unresolved and resolved resonance regions, respectively.

Cross-section-covariance data are used in the calculation of the uncertainty in keff due to uncertainties in the evaluated nuclear data.

The input for TSUNAMI-1D is similar to that used for the CSAS1X 1-D criticality safety analysis sequence of SCALE, with some additional input requirements.

TSUNAMI-1D produces a sensitivity data file in the TSUNAMI-A format. This data file contains the sensitivity of keff to each reaction of each nuclide on a group-wise basis. Additionally, the sensitivity of keff for each nuclide and each reaction of each mixture and material zone are available on a group-wise basis. This data file is formatted for viewing Javapeno and further analysis with TSUNAMI-IP.

TSUNAMI-3D

The TSUNAMI-3D sequence computes the sensitivity of keff to cross-section data for explict 3-D system models. The KENO V.a module is used to produce forward and adjoint neutron transport solutions and the SAMS module is used to produce sensitivity coefficients. The BONAMIST and NITAWLST modules are used to produce the sensitivity of the resonance self-shielded multigroup cross-section data to input data for the unresolved and resolved resonance regions, respectively.

Cross-section-covariance data are used in the calculation of the uncertainty in keff due to uncertainties in the evaluated nuclear data.

The input for TSUNAMI-3D is similar to that used for the CSAS25 3-D criticality safety analysis sequence of SCALE, with some additional input requirements.

TSUNAMI-3D produces a sensitivity data file in the TSUNAMI-B format. This data file contains the sensitivity of keff to each reaction of each nuclide on a group-wise basis. Additionally, the sensitivity of keff for each nuclide and each reaction of each mixture and material zone are available on a group-wise basis. This data file is formatted for viewing Javapeno and further analysis with TSUNAMI-IP.
