3. DESCRIPTION

The ENEA-Bologna Nuclear Data Group generated the BUGENDF70.BOLIB /1/ library in FIDO-ANISN format. BUGENDF70.BOLIB is a broad-group coupled neutron and photon working cross section library, dedicated to LWR shielding and pressure vessel dosimetry applications and it is based on the US ENDF/B-VII.0 /2/ library of evaluated nuclear data. The neutron and photon energy group structures (47 neutron groups + 20 photon groups) of BUGENDF70.BOLIB are the same as those of the corresponding BUGLE-96 /3/ similar library generated at ORNL in 1996, based on the US ENDF/B-VI.3 evaluated nuclear data. BUGENDF70.BOLIB was produced from the ENEA-Bologna VITENDF70.BOLIB /4/ fine-group mother library in AMPX format, based on ENDF/B-VII.0 data. The fine-group data of VITENDF70.BOLIB were collapsed and in some cases shelf-shielded, through the ENEA-Bologna 2007 Revision /5/ of the SCAMPI /6/ nuclear data processing system, using neutron and photon flux spectra typical of PWR and BWR reactor models. BUGENDF70.BOLIB, differently from BUGLE-96 which contains only prompt neutron fission spectra and prompt neutrons per fission data, includes total (prompt + delayed) neutron fission spectra for 34 fissionable nuclides (Am-242 not included because MF=4 MT=18 missing in the evaluated data) and total (prompt + delayed) neutrons per fission for 35 fissionable nuclides. The ENEA-Bologna VITENDF70.BOLIB and BUGENDF70.BOLIB libraries, based on US ENDF/B-VII.0 data, have similar counterparts respectively in the VITJEFF311.BOLIB /7/ and BUGJEFF311.BOLIB /8/ libraries, based on OECD-NEADB JEFF-3.1.1 /9/ /10/ data.

The BUGENDF70.BOLIB library package consists of two major parts:

BUGENDF70.BOLIB - Version without upscattering cross sections including an

infinite dilution cross section set for 183 nuclides and

six sets of parameterized self-shielded cross sections

containing a total of 124 nuclides.

Each set of parameterized cross sections includes part of

the 183 nuclides previously cited and the cross sections

contained are properly self-shielded, i.e., take into

account the specific temperature and background cross

section of the specific nuclide constituent of a typical

BWR or PWR material mixture.

BUGENDF70T.BOLIB - Version with upscattering cross sections including the same

cross section sets as BUGENDF70.BOLIB with the thermal

neutron upscattering cross sections retained in the thermal

neutron energy region below 5.0435 eV: upscatter data for

four thermal neutron groups are included. The upscatter

data should improve the application of this library to the

calculation of more accurate thermal fluences, although

more computer time will be required.

A preliminary testing of the BUGENDF70.BOLIB library was performed through three-dimensional fixed source transport calculations with the TORT-3.2 discrete ordinates (SN) code on the PCA-Replica 12/13 and VENUS-3 engineering neutron shielding benchmark experiments, included in the SINBAD international database of fission reactor shielding integral experiments. The two cited experiments were specifically conceived to check the nuclear data and transport codes used in LWR radiation shielding and radiation damage analyses.

NEUTRON AND PHOTON WEIGHTING SPECTRA:

Five fine-group (199 neutron groups + 42 photon groups) neutron and photon problem-dependent weighting spectra were employed to generate the BUGENDF70.BOLIB cross sections through VITENDF70.BOLIB cross section collapsing. These problem-dependent weighting spectra were pre-calculated with the XSDRNPM one-dimensional transport module of the ENEA-Bologna 2007 Revision of the ORNL SCAMPI system. The calculations were performed in representative spatial locations of the radial geometries of the BWR and PWR one-dimensional models. In particular neutron and photon flux spectra calculated in the following five specific locations were used to obtain the collapsed cross section sets:

1) off-center in a BWR core region;

2) off-center in a PWR core region;

3) within the downcomer region in a PWR model;

4) within the PWR pressure vessel (PV) at a depth of one-fourth the total

thickness (T) (1/4 T PV);

5) within the concrete shield surrounding a PWR pressure vessel.

In particular an infinite dilution cross section set containing 183 materials was generated through cross section collapsing using the neutron and photon flux spectra calculated within the concrete shield surrounding a PWR reactor pressure vessel. The concrete-spectrum-weighted cross sections have been shown to be generally applicable to a wide range of shielding problems. In addition, six parameterized cross section sets of self-shielded cross sections for variuos material mixtures, typical of BWR and PWR compositional models, were produced with the neutron and photon flux spectra calculated in the cited spatial locations.

RESPONSE FUNCTIONS

The BUGENDF70.BOLIB library contains several types of response functions.

"General Neutron Response Functions"

This set of data includes the neutron group upper energies, the group energy widths, the group lethargy widths, the group midpoint energies (E-mid), the group square-roots of E-mid and the group multiplicative factors for the total neutron flux, the E>1.0 MeV neutron flux, the E>0.1 MeV neutron flux and the E<0.414 eV neutron flux.

"Total Neutron Fission Spectra (chi) and Total Neutrons per Fission (nu)"

This set of data includes the total (prompt + delayed) neutron fission spectra (chi) for 34 fissionable nuclides (Am-242 not included because MF=4 MT=18 missing in the evaluated data) and the total (prompt + delayed) neutrons per fission (nu) for 35 fissionable nuclides. The total neutrons per fission were obtained with two different weighting spectra: flat weighting and 1/4 T PV weighting.

"IAEA IRDF-2002 Neutron Dosimeter Cross Sections"

This set of data contains the dosimeter cross sections for all the 71 nuclear reactions included in the IAEA IRDF-2002 International Reactor Dosimetry File. The IRDF-2002 neutron dosimeter cross sections were processed in the 47 neutron group structure of BUGENDF70.BOLIB with two different neutron weighting spectra: flat weighting and 1/4 T PV weighting.

"Neutron and Photon KERMA Factors"

This set of data includes the neutron KERMA factors for all the 183 materials contained in the infinite dilution cross section set of BUGENDF70.BOLIB and the photon KERMA factors are given for the corresponding 53 natural elements. The collapsing of the neutron and photon KERMA factors was obtained by using respectively the neutron and photon flux spectra calculated within the concrete shield surrounding a PWR pressure vessel.

The ENEA-Bologna Nuclear Data Group generated the BUGENDF70.BOLIB /1/ library in FIDO-ANISN format. BUGENDF70.BOLIB is a broad-group coupled neutron and photon working cross section library, dedicated to LWR shielding and pressure vessel dosimetry applications and it is based on the US ENDF/B-VII.0 /2/ library of evaluated nuclear data.

4. METHODS

The BUGENDF70.BOLIB library was generated, through cross section collapsing of the ENEA-Bologna VITENDF70.BOLIB /4/ fine-group general-purpose library for nuclear fission applications, using the updated and corrected ENEA-Bologna 2007 Revision /5/ of the ORNL SCAMPI /6/ nuclear data processing system. In particular this ENEA-Bologna version of the SCAMPI system, already transferred to OECD-NEA Data Bank (PSR-0352/05 SCAMPI), permits to obtain the total (prompt + delayed) neutron fission spectra and the total (prompt + delayed) neutrons per fission data of the fissionable nuclides, differently from the original version of SCAMPI developed at ORNL.

The adopted cross section processing methodology for BUGENDF70.BOLIB is the same as that used for producing the BUGLE-96 library and is consistent with the ANSI/ANS 6.1.2-1999 (R2009) /11/ American National Standard, reapproved in 2009.

The VITENDF70.BOLIB cross sections were generated with the LANL NJOY-99.259 data processing system and were converted into the AMPX format using the SMILER module of the previously cited ENEA-Bologna 2007 Revision of the SCAMPI system. VITENDF70.BOLIB is a pseudo-problem-independent library based on the Bondarenko /12/ (f-factor) method for the treatment of neutron resonance self-shielding and temperature effects. It has the same neutron and photon energy group structures (199 neutron groups + 42 photon groups) as the ORNL VITAMIN-B6 /3/ library in AMPX format (based on the ENDF/B-VI.3 evaluated nuclear data) from which the BUGLE-96 library was generated at ORNL.

The VITENDF70.BOLIB library contains 183 nuclides: 177 nuclides at 4 temperatures, most of them obtained with 6 to 8 values of the background cross section. The Fe-56 processed file was obtained with an additional value (0.01 barns) for the background cross section with respect to the background cross section values used to generate the corresponding data file for VITAMIN-B6.

Thermal scattering cross sections were processed at all the temperatures available in the ENDF/B-VII.0 thermal scattering law data file for 6 additional bound nuclides: (H-1 in light water (H-H2O), H-1 in polyethylene (H-CH2), H-1 in zirconium hydride (H-ZrH), H-2 deuterium (D) in heavy water (D-D2O), C in graphite (C-Gph) and Be in beryllium metal thermal (Be-Th)).

From VITENDF70.BOLIB it is possible to generate easily, through further proper data processing, working libraries of collapsed and self-shielded cross sections in AMPX format for calculations with the AMPX, SCAMPI and SCALE systems or in FIDO-ANISN format (as for example the BUGENDF70.BOLIB library) for calculations with the DOORS and PARTISN deterministic transport systems and finally for calculations with the MORSE Monte Carlo code.

This problem-dependent data processing must be exclusively performed through the ENEA-Bologna 2007 Revision of the SCAMPI system that can read the binary files generated by NJOY-99 with double precision data.

The BUGENDF70.BOLIB library was generated, through cross section collapsing of the ENEA-Bologna VITENDF70.BOLIB /4/ fine-group general-purpose library for nuclear fission applications, using the updated and corrected ENEA-Bologna 2007 Revision /5/ of the ORNL SCAMPI /6/ nuclear data processing system. In particular this ENEA-Bologna version of the SCAMPI system, already transferred to OECD-NEA Data Bank (PSR-0352/05 SCAMPI), permits to obtain the total (prompt + delayed) neutron fission spectra and the total (prompt + delayed) neutrons per fission data of the fissionable nuclides, differently from the original version of SCAMPI developed at ORNL.

The adopted cross section processing methodology for BUGENDF70.BOLIB is the same as that used for producing the BUGLE-96 library and is consistent with the ANSI/ANS 6.1.2-1999 (R2009) /11/ American National Standard, reapproved in 2009.

The VITENDF70.BOLIB cross sections were generated with the LANL NJOY-99.259 data processing system and were converted into the AMPX format using the SMILER module of the previously cited ENEA-Bologna 2007 Revision of the SCAMPI system. VITENDF70.BOLIB is a pseudo-problem-independent library based on the Bondarenko /12/ (f-factor) method for the treatment of neutron resonance self-shielding and temperature effects. It has the same neutron and photon energy group structures (199 neutron groups + 42 photon groups) as the ORNL VITAMIN-B6 /3/ library in AMPX format (based on the ENDF/B-VI.3 evaluated nuclear data) from which the BUGLE-96 library was generated at ORNL.

The VITENDF70.BOLIB library contains 183 nuclides: 177 nuclides at 4 temperatures, most of them obtained with 6 to 8 values of the background cross section. The Fe-56 processed file was obtained with an additional value (0.01 barns) for the background cross section with respect to the background cross section values used to generate the corresponding data file for VITAMIN-B6.

Thermal scattering cross sections were processed at all the temperatures available in the ENDF/B-VII.0 thermal scattering law data file for 6 additional bound nuclides: (H-1 in light water (H-H2O), H-1 in polyethylene (H-CH2), H-1 in zirconium hydride (H-ZrH), H-2 deuterium (D) in heavy water (D-D2O), C in graphite (C-Gph) and Be in beryllium metal thermal (Be-Th)).

From VITENDF70.BOLIB it is possible to generate easily, through further proper data processing, working libraries of collapsed and self-shielded cross sections in AMPX format for calculations with the AMPX, SCAMPI and SCALE systems or in FIDO-ANISN format (as for example the BUGENDF70.BOLIB library) for calculations with the DOORS and PARTISN deterministic transport systems and finally for calculations with the MORSE Monte Carlo code.

This problem-dependent data processing must be exclusively performed through the ENEA-Bologna 2007 Revision of the SCAMPI system that can read the binary files generated by NJOY-99 with double precision data.
