Three dimensional perturbation analysis of a fast reactor core

- Safety analysis of PFBR core employs 2D perturbation code.
- 3D perturbation code is developed for better reactivity predictions.
- 3D diffusion code FARCOB and ABBN-93 nuclear data are used.
- Developed code is giving close results with 2D and comparable results with ERANOS.
- The developed code will improve the safety analysis tools in IGCAR.
