1 INTRODUCTION

bull ERANOS 21 is a system of neutron and gamma codes developed within a European framework

bull This system meets the needs expressed by the industrialists and the teams working on the design of fast reactors present and future

bull It allows moreover with the use of the convivial LU userrsquos language to perform programs of RampD in reactor physics without systematically needing specific developments

3

2 ERANOS FUNCTIONS

bull Fast reactor core shielding and fuel cycle calculations can be performed with the ERANOS system ERANOS is a deterministic code system so neutron physics calculations are performed at the celllattice level and at the core level

bull The celllattice code ECCO (European Cell COde) is fed by libraries that are in a direct access format in various energy meshes 1968 groups (all-purpose) 175 groups (shielding purposes) the 172-group XMAS scheme (refined in the low energy range) and 33 groups (energy mesh generally used for core calculations)

bull Four sets of libraries can be used JEF-22 obtained directly from JEF22 evaluations ERALIB1 obtained from the JEF-22 libraries by a statistical fitting on

integral experiments JEFF-31 obtained directly from JEFF31 evaluations ENDFB-VI8 obtained directly from ENDFB-VI8 evaluations

NB The Code HETAIRE and the library CARNAVAL4 of the old Fast Neutron CEA code system are also available in ERANOS 21 For neutron shielding and gamma propagation and heating applications the PROPANE and VASCO libraries are also available

2 ERANOS FUNCTIONS

bull The ECCO code solves the resonant nuclide self-shielding using the sub-group method and computing with a collision probability method a fine-group solution of the transport integral equation The cross-sections can be condensed and homogenized

bull ECCO can model the following geometries Plane Cylindrical 2D rectangular sub-assembly with or without wrapper2D hexagonal sub-assembly with or without wrapper 3D slab geometry useful to model platelet fuel

bull The core calculations carried out by ERANOS include reactivity flux spatial power distribution reactivity coefficients burnup and control rod worth Moreover for very different applications (analysis of experiments reactivity coefficients follow-up and management of core loadings) traditional generalized and harmonics perturbation modules are available

5

2 ERANOS FUNCTIONS

bull The ERANOS code system is a very open system modular whose objects (SET or EDL) are easy to handle by many modules and the LU user language This makes possible using the various available modules to create procedures for specific types of applications eg to define separately design and reference calculations schemes for respectively scoping and detailed calculations

bull Calculations performed by ERANOS are gathered according to the following chapters

Operating Conditions Internal Transfer of nuclear dataRelease of energy and damage to the structures Diffusion modules 1D 2D (XY RZ and Hexagonal) 3D Hexagonal Z Sn transport modules 1D 2D (XY and RZ ) Nodal diffusion and transport modules P1 P3 P5 SP3 SP5 (XY XYZ

bull A procedure allows to encapsulate a sequence of LU instructions

bull A procedure is similar to a function

bull A procedure is a particular SET (SET of type PROCEDURE V1)

bull A procedure may be store on a permanent file (ARCHIVE file)

45 Processing scheme

bull Evaluated libraries in ENDF-6 format

bull It mainly relies on two important processing codes

NJOY (resonance integrals fission spectrum averaged Graphical plots of cross sections angular distributions and emitted spectra for

all isotopes and elements at all temperatures)

CALENDF (convert resolved and unresolved resonance parameters from ENDF-6 structured evaluations into temperature dependent

point- wise cross-sections it generates cross-section probability tablesldquo based on Gauss quadrature These represent detailed resonance self shielding within any of the groups and can be

used directly in the ECCO cell code)

and two interface codes MERGE GECCO

all of which have been largely updated since the last ECCOLIB was generatedSome major improvements have been achieved in the format and physical qualities of the basic JEFF-31 evaluations input

bullThe calling sentence is formed as follows The first word is the module name which identifies the function The following terms are specified in the directions for use of the module

bull Generally they are - Created or used SETS - Directives to describe the data to be given by the user - The semicolon ends the sentence

44

When the module name expresses without ambiguity the waited resulting SET the LU name of the variable SET preceded by an arrow will immediately follow the module name

5 USER LANGUAGE

bullIt is the LU language of the ALOS system Its basic instruction is the calling sentence of a module

bullThe calling sentence is formed as follows The first word is the module name which identifies the function The following terms are specified in the directions for use of the module

bull Generally they are - Created or used SETS - Directives to describe the data to be given by the user - The semicolon ends the sentence

44

When the module name expresses without ambiguity the waited resulting SET the LU name of the variable SET preceded by an arrow will immediately follow the module name

CREATION_MACRO -gtma

When the module name expresses without ambiguity the used SET the LU name of the used SET between brackets will immediately follow the module name
