A more feasible +approach is to create a reactor database where a finite number of lattice +calculation results are tabulated against selected {\sl global parameters} +chosen so as to represent expected operating conditions of the reactor. The +\moc{APX:} operator is used to create and construct a {\sc APEX} file. +The APEX file is written in {\sc hdf5} format, allowing full portability and hierarchical +data organization. It can be edited and modified using the HDFView tool. + +\vskip 0.1cm + +Each elementary calculation is characterized by a tuple of {\sl global parameters}. +These global parameters are of different types, depending on the nature of the +study under consideration: type of assembly, power, temperature in a mixture, +concentration of an isotope, time, burnup or exposure rate in a depletion calculation, +etc. Each step of a depletion calculation represents an elementary calculation. +The {\sc APEX} file is often presented as a {\sl multi-parameter reactor database}. + +\vskip 0.1cm + +For each elementary calculation, the results are recovered from the output of the +\moc{EDI:} operator and stored in a set of {\sl homogenized mixture} +directories. The \moc{EDI:} operator is responsible for performing condensation +in energy and homogenization in space of the macroscopic and microscopic cross +sections. All the elementary calculations gathered in a single {\sc apex} file are +characterized by a single output geometry and a unique output energy-group +structure. + +\vskip 0.1cm + +In each homogenized mixture directory, the \moc{APX:} operator recover +cross sections for a number of {\sl particularized isotopes} and {\sl macroscopic total and/or +residual sets}, a collection of isotopic cross sections weighted by isotopic number densities. +Cross sections for particularized isotopes and macroscopic sets are recovered for +{\sl selected reactions}. Other information is also recovered: multigroup neutron +fluxes, isotopic number densities, fission spectrum and yields, SPH or discontinuity factors and +albedos. Discontinuity factors and equivalent albedos are written in group {\tt miscelleaneous}. +Finally, note that cross section information written on the {\sc apex} file is {\sl not} +transport corrected and {\sl not} SPH corrected. + +\vskip 0.1cm + +A different specification of the \moc{APX:} function call is used for +creation and construction of the {\sc apex} file. +\begin{itemize} +\item The first specification is used to initialize the {\sc apex} data structure +as a function of the \dds{microlib} used in the reference calculation. The initialization +call is also used to set the choice of global parameters, local variables, particularized +isotopes, macroscopic sets and selected reactions. +\item A modification call to the \moc{APX:} function is performed after each +elementary calculation in order to recover output information processed by \moc{EDI:} +(condensed and homogenized cross sections) and \moc{EVO:} (burnup dependant values). +Global parameters and local variables can optionnally be recovered from \dds{microlib} +objects. The \moc{EDI:} calculation is generally performed with option {\tt MICR ALL}. +\end{itemize} + +The calling specifications are: + +\vskip -0.5cm + +\begin{DataStructure}{Structure \dstr{APX:}} +$\{$~~\dusa{APXNAM} \moc{:=} \moc{APX:} $[$ \dusa{APXNAM} $]~[$~\dusa{HMIC} $]$ \moc{::} \dstr{apex\_data1} \\ +~~~$|$~~~\dusa{APXNAM} \moc{:=} \moc{APX:} \dusa{APXNAM}~\dusa{EDINAM}~$[$ \dusa{BRNNAM} $]$ \moc{::} \dstr{apex\_data2} \\ +~~~$|$~~~\dusa{APXNAM} \moc{:=} \moc{APX:} \dusa{APXNAM} $[[$ \dusa{APXRHS} $]]$ \moc{::} \dstr{apex\_data3} $\}$ \\ +\end{DataStructure} + +\noindent where +\begin{ListeDeDescription}{mmmmmmm} + +\item[\dusa{APXNAM}] {\tt character*12} name of the {\sc lcm} object containing the +{\sl master} {\sc apex} data structure. + +\item[\dusa{HMIC}] {\tt character*12} name of the reference \dds{microlib} (type {\tt +L\_LIBRARY}) containing the microscopic cross sections.
