Implementation and benchmarking of ENDFVII based library for PBM reactor analysis with MCNP4c

Complexity in PBMR – Pebble Bed Modular Reactor – design has brought nuclear engineers to use Monte-Carlo based nuclear codes to analyze it. In this work we tried to improve the ability of the MCNP4c code in the analysis of such reactors. The improvement was reached through the updating of the cross-section library. Our main goal was to implement a new multi-temperature ENDFVII based library into MCNP4c and study its effects on PBM reactor analysis through the benchmarking process.

► Modelling of the HTR-10 reactor core.
► Implementation of the ADS 2.0 library in MCNP4c.
► Running Benchmark problems for the newly implemented library.
► Comparison of the results with results obtained using the standard library.
