3. DESCRIPTION

The ENEA-Bologna Nuclear Data Group generated the BUGJEFF311.BOLIB /1/ library in FIDO-ANISN format. BUGJEFF311.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 OECD-NEA Data Bank JEFF-3.1.1 /2//3/ library of evaluated nuclear data. The neutron and photon energy group structures (47 neutron groups + 20 photon groups) of BUGJEFF311.BOLIB are the same as those of the corresponding BUGLE-96 /4/ similar library generated at ORNL in 1996, based on ENDF/B-VI.3 evaluated nuclear data. BUGJEFF311.BOLIB was produced from the ENEA-Bologna VITJEFF311.BOLIB /5/ fine-group mother library in AMPX format, based on JEFF-3.1.1 data.

The fine-group data of VITJEFF311.BOLIB were collapsed and in some cases self-shielded, through the ENEA-Bologna 2007 Revision /6/ of the SCAMPI /7/ nuclear data processing system, using neutron and photon flux spectra typical of PWR and BWR reactor models. The ENEA-BOLOGNA VITJEFF311.BOLIB and BUGJEFF311.BOLIB libraries can be respectively considered as European counterparts of the ORNL VITAMIN-B6 /4/ and BUGLE-96 libraries. BUGJEFF311.BOLIB, differently from BUGLE-96 which contains only prompt neutron fission spectra (chi) and prompt neutrons per fission (nu) data, includes total (prompt + delayed) neutron fission spectra and total (prompt + delayed) neutrons per fission for 35 fissionable nuclides.

The BUGJEFF311.BOLIB library package consists of two major parts:

BUGJEFF311.BOLIB - Version without upscattering cross sections including an infinite dilution

cross section set for 182 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 182 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.

BUGJEFF311T.BOLIB - Version with upscattering cross sections including the same cross section sets

as BUGJEFF311.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 BUGJEFF311.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 BUGJEFF311.BOLIB cross sections through VITJEFF311.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 182 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. With the neutron and photon flux spectra calculated in the cited spatial locations were produced, in addition, six parameterized cross section sets of self-shielded cross sections for various material mixtures, typical of BWR and PWR compositional models.

RESPONSE FUNCTIONS

The BUGJEFF311.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) and the total (prompt + delayed) neutrons per fission (nu) data for 35 fissionable nuclides. The total neutrons per fission were obtained with two different neutron 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 BUGJEFF311.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 182 materials contained in the infinite dilution cross section set of BUGJEFF311.BOLIB and the photon KERMA factors 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 reactor vessel.

4. METHODS

The BUGJEFF311.BOLIB library was generated, through cross section collapsing of the ENEA-Bologna VITJEFF311.BOLIB /5/ fine-group general-purpose library for nuclear fission applications, using the updated and corrected ENEA-Bologna 2007 Revision /6/ of the ORNL SCAMPI /7/ 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 BUGJEFF311.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) /8/ American National Standard, reapproved in 2009.

The VITJEFF311.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. VITJEFF311.BOLIB is a pseudo-problem-independent library based on the Bondarenko /9/ (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 /4/ library in AMPX format (based on ENDF/B-VI.3 evaluated nuclear data) from which the BUGLE-96 library was generated at ORNL.

The VITJEFF311.BOLIB library contains 182 nuclides: 176 nuclides at 4 temperatures, obtained for the most part with 6 to 8 values for 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 JEFF-3.1.1 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 VITJEFF311.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 BUGJEFF311.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 BUGJEFF311.BOLIB library was generated, through cross section collapsing of the ENEA-Bologna VITJEFF311.BOLIB /5/ fine-group general-purpose library for nuclear fission applications, using the updated and corrected ENEA-Bologna 2007 Revision /6/ of the ORNL SCAMPI /7/ 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 BUGJEFF311.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) /8/ American National Standard, reapproved in 2009.

The VITJEFF311.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. VITJEFF311.BOLIB is a pseudo-problem-independent library based on the Bondarenko /9/ (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 /4/ library in AMPX format (based on ENDF/B-VI.3 evaluated nuclear data) from which the BUGLE-96 library was generated at ORNL.

The VITJEFF311.BOLIB library contains 182 nuclides: 176 nuclides at 4 temperatures, obtained for the most part with 6 to 8 values for 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 JEFF-3.1.1 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 VITJEFF311.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 BUGJEFF311.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.
