GRUCON: Original destination In beginning of 60s, in the IPPE(Obninsk), the Nuclear Data Centre has been created. Since the Geneva Summit in 1955, the free exchange of data was agreed. The data libraries from different countries, with specific data representation formats (KEDAK, UKNDL, ENDL, ENDF), become available. GRUCON was conceived as a code system for preparation of the group microscopic constants from all variety of data. Over time, the variety of formats has been reduced to ENDF, problem changed, but GRUCON architecture, developed under the original task, has been kept. IAEA NDS Meeting, Vienna, Austria October 5-9, 2015

GRUCON Architecture T he GRUCON code is so called “application code package with standardized functional content“, because it includes: command language for describing of some computation scenarios; set of functional modules to fulfil some variety of calculations; system support - set of subroutines and functions for command interpretation, command execution, data preparation to calculations and exchange between different types of memory.

GRUCON-D vs. PREPRO-2015 comparison (D.L.Aldama, V.Sinitsa, A.Trkov) IAEA NDS Meeting, Vienna, Austria October 5-9, 2015 Library: ENDF/B-VII.1 Materials: H-1, O-16, Fe-56, U235, U-238, Pu239 Temperatures: 0K, 293.6K Representations: point wise cross sections (PENDF), group averaged in the 640 SAND-II group structure (MENDF) Weight function: constant Tolerance parameter: EPS=1.e-4 (PREPRO), EPS=1.e-3 (GRUCON) PREPRO-2015 modules: LINEAR, RECENT, FIXUP, GROUPIE GRUCON-D modules: ENDF, EXTRA, F/-S, NU/-S, R/T-S, S/A-S, S/C-S, S/E-S, S/I-S, S/T-S, S/G-F, U/D-S, PENDF Tools: COMPLOT and COMHARD modules of PREPRO have been used for visualization of calculation results and analysis of disagreements.

Problem, explanation, solution IAEA NDS Meeting, Vienna, Austria October 5-9, 2015 Problem 1. Averaged cross section in the last group

IAEA NDS Meeting, Vienna, Austria October 5-9, 2015 Problem 2. Components of potential elastic scattering cross section for missed spin groups. In case of Fe-56 (ENDF/B-VII.1): one resonance for L=2, J=5/2; no resonances with L=2, J=7/2. GRUCON adds, PREPRO neglects corresponding components. For agreement with PREPRO, temporary correction has been made in GRUCON (for comparison purposes only).

IAEA NDS Meeting, Vienna, Austria October 5-9, 2015 Problem 3. Interpolation scheme in the unresolved resonance region. According to ENDFB6 recommendation, interpolation law, pointed in ENDF file, should be used for cross sections. In PREPRO it is used for parameters. For agreement with PREPRO, the GRUCON input data was changed ( for comparison purposes only).

Plans and Projects IAEA NDS Meeting, Vienna, Austria October 5-9, 2015 Updating and development of the GRUCON-D package will be continued in following directions: 1. Expansion of the R/T-S module processing capability by including multi- canal multi-level resonance formulae LMF=7 ( the Reich-Moore-Limited formalism) 2. Expansion of the ACE module processing capability by including not yet implemented energy-angular distribution laws of MF=6. 3. Updating of the KERMA module for energy release calculations. 4. Updating of the A/E-D module for group transition matrices calculations. Works under GRUCON-B (basic) version will be started in the next year. It will include all functional modules (updated and extended) of original GRUCON, used for the ENDF/B-V processing. The work will be done in cooperation with Karlsruhe Technology Institute (Germany) in frame of Memorandum of Understanding ( ), now is preparing for signing at the end of 2015 year.
