Explore Alternative Transient Analysis Codes for Neutronic Operations

AI Thread Summary
The discussion focuses on the search for alternative transient analysis codes for neutronic operations, specifically comparing them to the S3K code currently in use. The ARROTTA code, developed by EPRI, is highlighted as a potential alternative, particularly when coupled with VIPRE-2, though its performance relative to S3K remains uncertain. Participants mention that many vendors use proprietary codes, limiting access to comparative information. Additionally, APROS, developed by VTT and Fortum, and PARCS from Purdue University are noted as other options worth exploring. Overall, there is a need for benchmark test results to facilitate a comparison among these codes.

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.

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.

Vendor methods are proprietary (trade secret) and the details are not available in the public domain.

Hello, I'm currently trying to compare theoretical results with an MCNP simulation. I'm using two discrete sets of data, intensity (probability) and linear attenuation coefficient, both functions of energy, to produce an attenuated energy spectrum after x-rays have passed through a thin layer of lead. I've been running through the calculations and I'm getting a higher average attenuated energy (~74 keV) than initial average energy (~33 keV). My guess is I'm doing something wrong somewhere...
