The IAEA-NDS-reports should not be considered as formal publications.
When a nuclear data library is sent out by the IAEA Nuclear Data Section, it will be
accompanied by an IAEA-NDS-report which should give the data user all necessary
documentation on contents, format and origin of the data library.
IAEA-NDS-reports are updated whenever there is additional information of
relevance to the users of the data library.
For citations care should be taken that credit is given to the author of
the data library and/or to the data center which issued the data library. The editor of
the IAEA-NDS-report is usually not the author of the data library.
Neither the originator of the data libraries nor the IAEA assume any
liability for their correctness or for any damages resulting from their use.

A.B. Pashchenko and H. Wienke
The library FENDL/E-2.0, version 1 of March 1997, contains selected evaluated neutron,
photon-atom, and photon production cross sections, in ENDF format, with resonance
parameters where appropriate, for 57 nuclides of importance for coupled neutron-photon
transport calculations for fusion reactor design. The energy ranges from 10-5
eV up to 20 MeV. The library has been developed from the previous version FENDL/E-1.1 [
Ref. 1] by including thirteen replacing evaluations and six for additional materials. The
new evaluations were selected by the FENDL/E-2.0 selection committee [Refs. 2,3],
according to the procedure agreed upon at the IAEA Advisory Group Meeting on
"Completion of FENDL-1 and Start of FENDL-2", Del Mar, California, USA, 5-9 Dec.
1995 [Ref. 4], from candidate evaluations submitted by five national projects viz.
JENDL-FF (Japan), BROND (Russia), EFF (European Union), ENDF/B-VI (USA) and CENDL (China).
The neutron-nucleus interaction and photon production cross sections have been selected
from the following evaluated nuclear data libraries:
- BROND-2: BROND library version 2 contributed by the Russian Federation, see document
IAEA-NDS-90 Rev. 8. [Ref. 5]
- ENDF/B-VI.x: ENDF/B library version VI, revision x contributed by the U.S.A., see
document IAEA-NDS-100 Rev. 6. [Ref. 6]. Note that revision x is the revision number of the
given material, not of the library.
- JENDL-3.1: JENDL library version 3.1 contributed by Japan, see document IAEA-NDS-110
Rev. 4. [Ref. 7].
- JENDL-FF: JENDL Fusion file contributed by Japan [Ref. 8].
- EFF-3: European Fusion library version 3 contributed by the European Community [Ref.
BROND-2, ENDF/B-VI, JENDL-FF and EFF-3 are in ENDF-6 format, see document IAEA-NDS-76
Rev. 4. [Ref. 10], JENDL-3.1 is in ENDF-5 format, see document IAEA-NDS-75, Rev.1 [Ref.
11]. The FENDL/E-1.0 Evaluations for photon-atom interaction are all taken from ENDF/B-VI
photon-atom interaction Library, see report IAEA-NDS-58 Rev.2 [ Ref. 12].
The preliminary selection of evaluations for inclusion in FENDL/E-2.0
was made at the IAEA Consultant's Meeting on "Selection of Basic Evaluations for the
FENDL-2 Library", held at Karlsruhe, Germany, June 24-28, 1996 [Ref. 3]. This
preliminary selection was established by applying the following criteria [Refs. 3,4,13]:
- Presence of gamma ray production cross sections and spectra
- Correlated energy-angle neutron and charged particle emission data (MF=6).
- Recoil distributions in MF=6 format for major structural materials (recommended for other materials).
- Energy balance better than 2% at all energies.
- MF=1 descriptive information.
- Presence of uncertainty information.
- Use of Standard Reference Data such as IRDF-90.2 dosimetry cross
sections in candidate files highly recommended.
For the final adoption of the pre-selected evaluations several actions,
requested at the last mentioned meeting, were completed by the contributing parties. Based
upon the results of these actions the final adoption was made at the IAEA Advisory Group
Meeting on "Extension and Improvement of the FENDL Library for Fusion Applications
(FENDL-2)", held in Vienna, March 3-7, 1997 [Ref. 14 ]. At this meeting it was agreed
to include in the basic library FENDL/E-2.0 also the ENDF/B-6 evaluations for 3,4He
and 197Au. These have not been reviewed for FENDL but are contained in the
current processed libraries as their need was recognized since the materials are used in
fusion applications. Also the JENDL-3 evaluation for natGa was included as this
material is used as a coolant in fusion reactors. The selected evaluation does not satisfy
the criteria setup for FENDL evaluations (no g-production data) but is the only available
Table 1 lists the materials included in
The data are available from the IAEA Nuclear Data
Section in ftp subdirectory "UD7: [FENDL2.TRANSPORT.FENDLE]". This subdirectory
has a total size of about 51.4 Megabytes and includes 57 data files plus a file named
aaareadme.www containing the information presented in this summary. The nuclear data files
for each of the isotopes/elements have been identified individually with names such as:
"H002BR2.DAT" for the data of H-2 from BROND-2,
"SI030E6.DAT" for the data of Si-30 from ENDF/B-VI,
"MO000JFF.DAT" for the data of Mo-nat from JENDL-FF,
"FE056EFF3.DAT" for the data of Fe-56 from EFF-3
"TA181J3.DAT" for the data of Ta-181
The atomic number is always written with three
digits, starting with a '0' when it is smaller than 100 and '00' when smaller than 10.
All the photon-atom interaction cross section
data are available in one single file named "FENDLEP.dat". A list of FENDL/E-2.0
evaluations for neutron interaction and photon production cross sections is presented in
Appendix A and that of evaluations for photon-atom interactions in Appendix B.

As was agreed at the Del Mar-95 AGM the contributors of the new evaluations also
provided to the NDS the processed cross section data which were derived from the these
evaluations with the nuclear data processing code NJOY [Ref. 15]. The processed cross
sections were in pointwise ACE format, for use with the Monte Carlo transport code MCNP
[Ref. 16], and in the multigroup GENDF and MATXS formats, for use in coupled
neutron-photon transport calculations with discrete-ordinates codes like ANISN, ONEDANT,
etc, to be included in the working sublibraries FENDL/MC-2.0 and FENDL/MG-2.0 [Ref. 17]
These processed contributions, however, were primarily
generated for the purpose of benchmark analysis and, as was found upon closer inspection
at IAEA/NDS, the specifications for processing, used by the various contributing parties,
were not uniform. Therefore and also in view of the improvements and new options
incorporated in the most recent version of NJOY94, it was agreed, at the Vienna-97
Advisory Group Meeting, that all evaluations, including those carried over from
FENDL/E-1.0, should be reprocessed, using NJOY94 version 61 and later versions. Each party
should process their own selected evaluations and the processed multigroup and ACE data
files should be submitted to IAEA/NDS by October 1, 1997. Quality assurance tests will be
performed by J. White, RSIC, ORNL, USA, and results submitted to IAEA/NDS by November 30.
