India’s PFBR attains criticality at last
Prime Minister Narendra Modi proclaimed it “a proud moment for India” when on April 6 the 500-MWe, sodium-cooled Prototype Fast Breeder Reactor (PFBR) achieved initial criticality. This milestone, which comes some 22 years after the continually delayed PFBR project began, marks India’s entrance into the second stage of its three-stage nuclear program, which has the ultimate goal of supporting the country’s nuclear power program with its significant thorium reserves.

VERA—Virtual Environment for Reactor Applications—is a state-of-the-art Light Water Reactor (LWR) core simulator using novel computational methods that integrates reactor physics, thermal hydraulics, and fuel performance into a single simulation platform. The goal of this workshop is to provide a series of lectures and calculation demonstrations for trainees to learn the basic principles of VERA modeling for Pressurized Water Reactors (PWRs). The workshop will provide basic modeling demonstrations and exercises for pin, assembly, and full-core simulations. New features developed for Boiling Water Reactor calculations will also be demonstrated.
VERA developers and analysts from ORNL and VeraCity Nuclear, LLC will provide this training. Participants do not need to have a VERA license to attend. The trainers will be performing calculations during the training using computational resources at the Nuclear Computational Resource Center (NCRC) at Idaho National Laboratory (INL). License, code access, and use of INL NCRC will be discussed throughout the training.
