\subsection{The \moc{DSET:} module}\label{sect:dset} \vskip 0.2cm The \moc{DSET:} module is used to set or to update some of the devices parameters. The new parameters can be applied for the rod-type devices and/or for the liquid zone controllers, such as: the new insertion level for the rods or water filling level for the lzc-type devices, etc. It is possible to apply the new parameters to the individual user-selected devices as well as to the user-selected groups of devices. If the device (rod-insertion or lzc-filling) level is selected for the modification, then a new device position is recomputed accordingly. The \moc{DSET:} module can be used to perform the device reactivity studies and also to predict the reactivity worth of the rod-devices.\\ \noindent The \moc{DSET:} module specification is: \begin{DataStructure}{Structure \moc{DSET:}} \dusa{DEVICE} \moc{:=} \moc{DSET:} \dusa{DEVICE} \moc{::} \dstr{descdset} \end{DataStructure} \noindent where \begin{ListeDeDescription}{mmmmmmmm} \item[\dusa{DEVICE}] \texttt{character*12} name of the \dds{device} object that will be updated by the module. \item[\dstr{descdset}] structure describing the input data to the \moc{DSET:} module. \end{ListeDeDescription} \vskip 0.2cm \subsubsection{Input data to the \moc{DSET:} module}\label{sect:dsetstr} It is possible to set or to modify the parameters for several individual devices and/or for several groups of devices simultaneously. \begin{DataStructure}{Structure \dstr{descdset}} \moc{EDIT} \dusa{iprint} \\ $[[$ $\{$ \moc{ROD} \dusa{irod} $|$ \moc{ROD-GROUP} \dusa{irgrp} $|$ \moc{LZC} \dusa{ilzc} $|$ \moc{LZC-GROUP} \dusa{ilgrp} $\}$ \\ $[$ \moc{LEVEL} \dusa{value} $]$ $[$ \moc{SPEED} \dusa{speed} $]$ $[$ \moc{TIME} \dusa{time} $]$ \\ \moc{END} $]]$ \\ ; \end{DataStructure} \noindent where \begin{ListeDeDescription}{mmmmmmmm} \item[\moc{EDIT}] keyword used to set \dusa{iprint}. \item[\dusa{iprint}] integer index used to control the printing on screen: = 0 for no print; = 1 for minimum printing; larger values produce increasing amounts of output. \item[\moc{ROD}] keyword used to specify the rod \dusa{irod} number. \item[\dusa{irod}] integer identification number of a rod to be modified. Each rod-type device has a unique \dusa{irod} number, ranging from 1 to \dusa{nrod}, as been defined in the \moc{DEVINI:} module (see \Sect{devrodstr}). \item[\moc{ROD-GROUP}] keyword used to specify the rod-group \dusa{irgrp} number. \item[\dusa{irgrp}] integer identification number of a rod-group of devices that will be modifed with the same parameters. Each rod-group has a unique \dusa{irgrp} number, ranging from 1 to \dusa{ngrp}, as been defined in the \moc{DEVINI:} module (see \Sect{rodgroupstr}). \item[\moc{LZC}] keyword used to specify the liquid controller \dusa{ilzc} number. \item[\dusa{ilzc}] integer identification number of a liquid controller to be modified. Each lzc-type device has a unique \dusa{ilzc} number, ranging from 1 to \dusa{nlzc}, as been defined in the \moc{LZC:} module (see \Sect{devlzcstr}). \item[\moc{LZC-GROUP}] keyword used to specify the lzc-group \dusa{ilgrp} number. \item[\dusa{ilgrp}] integer identification number of a lzc-group of devices that will be modifed with the same parameters. Each lzc-group has a unique \dusa{ilgrp} number, ranging from 1 to \dusa{ngrp}, as been defined in the \moc{LZC:} module (see \Sect{lzcgroupstr}). \item[\moc{LEVEL}] keyword used to specify a new level \dusa{value}. \item[\dusa{value}] real positive value of the new device level. For the rod-type devices this \dusa{value} must correspond to the new rod insertion level (see \Sect{rodgroupstr}). For the lzc-type devices this \dusa{value} must correspond to the new water filling level (see \Sect{devlzcstr}). In any case, the new level value must be: 0.0 $\leq$ \dusa{value} $\leq$ 1.0 \item[\moc{SPEED}] keyword used to specify a new value for \dusa{speed}. \item[\dusa{speed}] real positive value of the device speed. For the rod-type devices this value must correspond to the speed of rod movement (insertion or extraction), given in cm/s. For the lzc-type devices this value must correspond to the water filling rate, given in m$^{3}$/s. The value of \dusa{speed} is required only for the reactor regulating purpose. \item[\moc{TIME}] keyword used to specify a new value for \dusa{time}. \item[\dusa{time}] real value of time either for the rod insertion (or extraction) \dusa{or} for the liquid controller filling, given in sec. The value of \dusa{time} is required only for the reactor regulating purpose. \item[\moc{END}] keyword used to indicate the end of input of the new parameters for the current device or group of devices. \end{ListeDeDescription} \clearpage
