Transient Analysis

MajestikMoose

At the moment I'n involved with a project that is using the S3K transient analysis code. I was wondering if anyone knows of a different code that will perform transient neutronic operations.

Thanks in advance

EPRI developed the ARROTTA code - 3D space-time kinetics code - for the purpose of reactor transient analysis. ARROTTA has been coupled with VIPRE-2. I don't know how well it performs with respect to S3K which is a fairly good code. The vendors have their own methods, but I believe they are not as advanced as S3K.

This paper might be useful - Parallel Computing Methods For The Epri Spatial Kinetics Code Arrotta

Thanks. I know that a lot of vendors use their own 'in-house' codes and don't distribute them commercially but is there any way of getting more information about them for a comparison to S3K? I'm trying to compare to see how they stand up to each other. Any type of benchmark test results would be useful.

VTT and Fortum (Finland) have developed APROS, but I don't know much about it.

There is a group in the Dept. of Nuclear Engineering at Purdue, who have developed PARCS, Purdue Advanced Reactor Core Simulator, which might be available.
