A program for computing the Xenon poisoning of the High Flux Reactor (HFR) of the ILL.

by A.Filhol and A. Robert


The input data are the dates and power for each steady functioning period. The main output quantities are the Xenon poisoning, the EFPD (Equivalent Full Power Days) and the "Control Rod Position". The algorithm accounts for both the Samarium et Xenon effects.
MacXenon is a rejuvenated version of an undocumented Fortran program written by André Robert in the seventies.
MacXenon is documented and offers a user friendly graphical interface.

The Mac OS (classic) version of the program was routinely used by the ILL reactor staff from 1995 to 2004.
In 2003 the program was ported to Windows by "ABC M informatique" (St Martin d'Hères). This version now replaces the Mac OS version.
