USE OF WIMS/PANTHER TO ANALYSE NITROGEN WORTH MEASUREMENTS AT THE UK FLEET OF AGRS
The UK fleet of Advanced Gas-Cooled Reactors (AGRs) are moderated with graphite and cooled with carbon dioxide.Each reactor consists of over 300 fuel channels with a cluster of UO2 fuel pins surrounded by graphite.Primary shutdown is achieved with control rods, which are at interstitial locations at six AGR stations, and in vacated fuel channels in
