A long time ago before RIPL …
(Recommended/any) inputs for nuclear reaction calculations ?
SNP2008, July 8-11Athens, OH, USA
Roberto Capote, IAEA Nuclear Data SectionE-mail: [email protected]
RIPL Background Nuclear reaction theory: sufficiently advanced to meet
most of the requirements for a number of applications Major sources of uncertainty are the input parameters
needed to perform theoretical calculations
Improve the methodology of nuclear data evaluation by increasing predictive power, accuracy and reliability of theoretical calculations by nuclear reaction model codes
RIPL Objective
Improved description of nuclear reactions, easier calculations allowing for a much better understanding
SNP2008, July 8-11Athens, OH, USA
Roberto Capote, IAEA Nuclear Data SectionE-mail: [email protected]
IAEA Nuclear Data Section has addressed these needs through a series of Coordinated Research Projects dedicated to the production of a Reference Input Parameter Library (RIPL)
1994 – 2008The longest running IAEA/NDS project

Reference Input Parameter Library
1994-1997: RIPL-1 starter file (http://www-nds.iaea.org/ripl/ )
Second CRP was initiated on “Nuclear Model Parameter Testing for Nuclear Data Evaluation (Reference Input Parameter Library: Phase II)”, and completed in 2003. Revision, extension and validation of the original RIPL-1 Starter File to produce a consistent RIPL-2 library of recommended input parameters.
Electronic Starter File (known as Reference Input Parameter Library-1) was developed and made available to users throughout the world in 1997 (compilation)
1998-2003: RIPL-2 database (http://www-nds.iaea.org/RIPL-2/)
Main goal: Energy applications, E<20MeV
SNP2008, July 8-11Athens, OH, USA
Roberto Capote, IAEA Nuclear Data SectionE-mail: [email protected]
RIPL-3 additional requirements Reactions at high energies for ADS (up to 150
MeV), production of medical radioisotopes (up to 100
MeV) and radiotherapy (up to 250 MeV)
Reactions on nuclei far from stability for ADS and
astrophysics
Charged-particle reactions for all non-energy
applications
Number of simple routines for the calculation of
basic input data from the parameters contained in the
library will be provided to reduce a risk of misusing
the parameters
SNP2008, July 8-11Athens, OH, USA

Reference Input Parameter LibraryThird (and final) CRP: “Parameters for Calculation of Nuclear Reactions of Relevance to Non-Energy Nuclear Application (Reference Input Parameter Library: Phase III)” started in 2003. The project is close to completion. The update of the RIPL-2 database will be released in September 2008.

CONCLUDING REMARKSOver many years, IAEA staff within the Nuclear Data Section have successfully initiated and overseen the completion of various projects dedicated to satisfying a wide range of user demands for enhancements in the quantification and quality of neutron reaction cross sections.
RIPL-4 hopefully will contain SMMC level densities
The RIPL-3 database represents considerable advancements in the adoption and use of evaluated and highly credible nuclear data both for energy and non-energy applications
One of the most significant database developments have involved important advances in the evolution of a complete and consistent set of input parameters for the calculation of a wide range of nuclear reactions.
Efforts will continue to develop this database further, and monitor all studies that impact and could possibly improve their contents.
