Direction - CMS5
• As faithful to physics as possible– Better basis for applications
• Ambition to increase use as method of record
• NRC Generic Licensing
May 2-3, 2012 International Users Group Meeting
Covering the fuel cycle
May, 2-3 International Users Group Meeting
Direction - Applications
• Richness of applications, e.g.– S3R– Gardel– SNF– ENIGMA– MARLA– COPERNICUS
• New tools for postprocessing, Java, Matlab
• Coupling of e.g. MARLA to customers present method of record
