6.3.3.1. Data File Formats

Several data file formats that are used by the sensitivity and uncertainty analysis codes are presented in this appendix.

6.3.3.1.1. Format of TSUNAMI-A sensitivity data file

The format of the TSUNAMI-A sensitivity data file produced by SAMS for cases with deterministic transport solutions is given in Table 6.3.6. The occurrence of each entry in the data file is followed by an identification of the data contained on each line of the file and the FORTRAN edit descriptor denoting the format of each line. A brief description of each line is also presented.

A sample of the TSUNAMI-A data file for the Flattop-25 sample problem is provided in Example 6.3.13. Here, only two profiles out of the 130 computed are shown.

Table 6.3.6 Format specification for TSUNAMI-A sensitivity data file.

Occurrence	Data	Format	Description
Once at beginning of file.	title	a80	Title extracted from transport calculation
	number of neutron groups	i10	Number of neutron groups in calculation
	total number of profiles, text descriptor, number of total profiles that are region integrated	i10, a35, i10	Total number of sensitivity profiles in data file, separated by a text descriptor, then the number of profiles that contain region-integrated data
	keff	f10.6	Value of keff from the forward transport calculation
	‘energy boundaries:’	a	Text
	energy boundary data	5es14.6 (repeats until all data is printed)	Values of boundaries of energy groups. Begins with upper value for highest energy group and ends with lower value of lowest energy group.
Repeats for each profile.	isotope name, sensitivity reaction name, nuclide ID, MT number, Zone number or negative of material number, zone volume	a12, 1x, a15, 3i12, es14.6	Provides data identifying the sensitivity data that follows. Note, if sensitivity data is region-integrated, zone number and zone volume are both 0. If data is integrated over all zones containing the same material, the material number is given in place of the zone number as a negative number.
	Energy integrated sensitivity coefficient, sum of absolute value of group-wise sensitivities, sum of the group-wise sensitivities with opposite sign as energy integrated value (osc)	3es14.6	Energy-integrated sensitivity coefficients for this profile.
	group-wise sensitivity coefficients	5es14.6 (repeats until all data is printed)	Energy-dependent sensitivity coefficients. Begins with highest energy group.
Once at end of file.			Block of file verification information.

6.3.3.1.2. Format of TSUNAMI-B sensitivity data file

The format of the TSUNAMI-B sensitivity data file produced by SAMS for cases with Monte Carlo transport solutions is given in Table 6.3.7. The occurrence of each entry in the data file is followed by an identification of the data contained on each line of the file and the FORTRAN edit descriptor denoting the format of each line. A brief description of each line is also presented.

A sample of the TSUNAMI-B data file for the LEU-COMP-THERM-009 case 10 sample problem is provided in Example 6.3.14. Here, only two profiles out of the 3389 computed are shown.

6.3.3.1.3. Format of HDF5-based sensitivity data file

An HDF5-based format for the sensitivity data files has been introduced. The format used here has been found to improve I/O speed for TSUNAMI-IP cases that read many SDF files. The HDF5-based SDF can be loaded in Fulcrum to produce the same plots that the text-based SDF can. The HDF5-based SDF may also be read with standard HDF5 tools such as h5dump, h5py, and HDFview.

The tao utility includes a feature that facilitates conversion between the HDF5-based SDF and the text-based SDF.

For example, the tao utility may be used to convert a batch of text-based SDF files in a directory into HDF5-based SDF files by:

tao convert *.sdf

Each HDF5-based SDF file has a file extension “.sdf.h5”. The tao convert tool may also be used to convert from HDF5 to the text-based format via

tao convert -fromFormat=sdf.h5 -toFormat=sdf <filename>.sdf.h5

For tao convert, the -fromFormat and -toFormat options take the intended file extension as the arguments.

The HDF5-based SDF may be requested as output from TSUNAMI calculations by including the sensitivity_format keyword in the SAMS block of the calculation input. For example:

read sams
  sensitivity_format=hdf5
end sams

will produce the result senstivity file in HDF5 format, with extension “.sdf.h5”. The default sensitivity output for TSUNAMI calculations is the text-based format described previously. This may be requested by removing the sensitivity_format keyword from the input file, or by

read sams
  sensitivity_format=txt
end sams

Brief Description of Data Layout

The HDF5 attributes are defined as

Table 6.3.8 HDF5-based SDF attributes

Name	Datatype	Comments: MC denotes “only in Monte Carlo-derived files”
file_type	string	The type of file - should be SDF_ARCHIVE
file_version	string	The version of the SDF HDF5 format used for this file
id_chk_sum	string	A simple checksum
id_spec	string	A link to the specification
title	string	The SDF title
sdf_type	enumeration	“MonteCarlo” or “Deterministic”
reference_quantity	string	The quantity of interest, e.g. keff
reference_comment	string	Any comment about the reference quantity
reference_value	double	The value of the reference quantity in the transport calculation
reference_sigma	double	MC Uncertainty in the reference value
number_profiles	int	The number of sensitivity profiles
number_region_integrated	int	The number of region-integrated sensitivity profiles
number_neutron_groups	int	The number of neutron groups for the sensitivity calculation
constrained_chi	bool	Whether the \(\chi\) (fission neutron spectrum, MT=1018) sensitivities are constrained
list_energies	vector<double>	Energy group boundaries, with size = number_neutron_groups + 1

The datasets are stored as vectors, each of size number_profiles. The exceptions are profile_values and profile_sigmas – in order to optimize I/O time (especially in TSUNAMI-IP and TSURFER calculations that read many SDFs), both of these datasets are hyperslabs of dimension number_profiles \(\times\) number_neutron_groups.

Table 6.3.9 SDF datasets

Name	Datatype	Comments: MC denotes “only present in Monte Carlo-derived files”
profile_values	double	The sensitivity coefficients
profile_sigmas	double	MC The uncertainties in the sensitivity coefficients
nuclide_id	int	The numerical IDs of the nuclides, in ZZAAA form
mt	int	The reaction ID (MT) values
comment	string	Any comment
region	int	Same conventions as text-based region values
region_uses	int	Number of times region has been used
material	int	Same conventions as text-based material values
unit	int	Same conventions as text-based unit values
volume	double	Volume of region
values_sum	double	Energy-integrated value of the sensitivity coefficients for corresponding profile
values_sigma	double	MC Uncertainty in energy-integrated value of the sensitivity coefficients for corresponding profile
values_abs_sum	double	Sum of absolute values of the sensitivity coefficients for corresponding profile
values_osc_sum	double	Sum of the sensitivity coefficients with sign opposite values_sigma for corresponding profile
values_osc_sigma	double	MC Uncertainty in values_osc_sum for corresponding profile

6.3.3.1.4. Format of SENLIB.SEN data file

The SENLIB.SEN data file is generated by the SENLIB routines used in the TSUNAMI modules to compute implicit sensitivity effects. The data file contains the sensitivity of data computed in SENLIB and input to the resonance processing code BONAMIST. This file also contains the sensitivities of the extra cross sections input to BONAMIST to the number densities of each nuclide for each region of the BONAMIST input. In BONAMIST, the extra cross section contains data for the Dancoff factor. Each of the parameters for which sensitivity coefficients are computed has a unique identification number. The parameter identification numbers, corresponding parameters, and their locations in the resonance processing code input are shown in Table 6.3.10. The format of the records of the SENLIB.SEN data file is given in Table 6.3.11. Each sensitivity coefficient is identified by three records. These records are repeated until all sensitivities are listed on the data file.

Table 6.3.10 Parameter identifiers for SENLIB.SEN data file.

Identifier number	Parameter	Location of parameter in resonance processing code input
-1004	Extra cross section (cm-1) by zone, account for Dancoff factor in BONAMIST	9* array in data block 2 of BONAMIST input

Table 6.3.11 Record format for SENLIB.SEN data file.

Record number	Data	Format	Description
1	Region for BONAMIST data and parameter	2i12	BONAMIST region and parameter for which sensitivity coefficient is computed.
2	Nuclide and reaction MT number to which sensitivity coefficient is computed	2i12	Nuclide and reaction MT number to which the sensitivity of the parameter is computed. For data currently computed by SENLIB, only the sensitivities of the parameters to the number densities of the nuclides are computed. Thus, the reaction MT number is always 1.
3	Sensitivity coefficient	es14.6	Relative sensitivity of parameter identified in first record to nuclide and reaction identified in second record.

6.3.3.1.5. Format of BONAMIST.SEN data file

The BONAMIST.SEN data file is generated by the BONAMIST code, which is executed as part of the TSUNAMI-1D sequence. This data file contains the sensitivities of the groupwise cross sections that are resonance shielded in BONAMIST to the certain data input to BONAMIST. The data to which the sensitivity coefficients are computed are the number densities of the nuclides and the extra cross section by region, which contains data for the Dancoff factor. These data are listed in the data file according to the identifiers listed in Table 6.3.10. Additionally, the sensitivity of group cross sections to the number density of a particular nuclide is identified with the nuclide number from the AMPX cross-section data library.

The format of the records in the data file is identified in Table 6.3.12. Blocks of these records are printed for the non-zero sensitivities for all nuclides and reactions for which resolved resonances are processed.

Table 6.3.12 Record format for BONAMIST.SEN data file.

Record number	Data	Format	Description
1	Nuclide and MT number for cross sections for which sensitivity coefficients are computed	2i12	Nuclide identifier and MT number of reaction for which sensitivity data are computed.
2	Parameter or nuclide and the MT number to which the sensitivity data are computed	2i12	Parameter identifier for scattering cross sections and Dancoff factor or nuclide identifier and MT number to which the sensitivity coefficients are computed. If a parameter identifier is used, the MT number is set to 1. Currently only the sensitivities to number densities are computed in BONAMIST, so the only MT number printed is 1.
3	First and last group for which sensitivity coefficients are printed	2i12	First and last group for the sensitivity coefficients that follow.
4	Sensitivity coefficients, record repeats until all groups identified by record 3 are printed	5es14.6	Relative sensitivities of cross sections for nuclide and process identified by record 1 to parameter or nuclide identified in record 2 for groups corresponding to those identified by record 3.

6.3.3.1.6. COVERX format

The COVERX data file format for storing multigroup cross-section uncertainty information is presented in this section. The COVERX format was used with the FORSS code system at ORNL. The covariance data processing code PUFF-III outputs multigroup data in the COVERX format. This the only covariance format available for use with the sensitivity and uncertainty analysis codes in SCALE.

The overall structure of a COVERX file is given in Table 6.3.13. The occurrence of the particular record type, the name of the record type and when a given record type is present on the file are identified.

Table 6.3.13 COVERX file structure.

Occurrence	Record type	Present if
Once at beginning of file	File Identification	Always
	File Control	Always
	File Description	NHOLL > 0
	Neutron Group Boundaries	NNGRUP > 0
	Gamma Group Boundaries	NGGRUP > 0
	Material-Reaction Control	Always
Repeat for all material-reaction type pairs	Material-Reaction Type Cross Sections and Error Files	Always
Repeat for all matrices	Matrix Control	Always
	Block Control	Always
Repeat for all blocks	Matrix Data	Always

The details of each record type identified in Table 6.3.13 are presented in Table 6.3.14. Here, the name of the record type, the variables present on the record, the length of the record, the format of the record in FORTRAN context and a description of the content of the record are given.
