Establishing Scaling Criteria of Prototype Fast Breeder Reactor Intermediate Heat Exchanger through Finite Element Modeling

Weapon-Grade Plutonium Production Potential in the Indian Prototype Fast Breeder Reactor

India is building a 500 MWe Prototype Fast Breeder Reactor, which is scheduled to be operational by 2010. India has refused to accept international safeguards on this facility, raising concerns that the plutonium produced in its uranium blankets might be used to make nuclear weapons. Based on neutronics calculations for a detailed threedimensional model of the reactor, we estimate that up to 14...

Compromising Safety: Design Choices and Severe Accident Possibilities in India's Prototype Fast Breeder Reactor

Intermediate Heat Exchanger Dynamic Thermal Response

This report presents UCB progress in developing a comprehensive thermal and fluid dynamics model for the NGNP intermediate heat exchanger (IHX) and other compact heat exchangers. For nuclear hydrogen applications, an IHX is required to transfer heat from high temperature and high-pressure primary helium coolant to a hydrogen production process. An intermediate heat transfer loop is used for the...

Zone Wise Analysis of Cavitation in Pressure Drop Devices of Prototype Fast Breeder Reactor by Kurtosis Based Recurrent Network

Former Director, FRTG, Indira Gandhi Centre for Atomic Research, Kalpakkam, Chennai 603 102, Tamilnadu, India Email: [email protected] Abstract: This paper aims to analyze the quality of pressure drop devices (orifices), which is used for flow zoning in proto type fast breeder reactor (PFBR) by analyzing the occurrence of cavitation. The magnitude of root mean square (RMS) of the acoustic time s...

Fast Finite Element Method Using Multi-Step Mesh Process

This paper introduces a new method for accelerating current sluggish FEM and improving memory demand in FEM problems with high node resolution or bulky structures. Like most of the numerical methods, FEM results to a matrix equation which normally has huge dimension. Breaking the main matrix equation into several smaller size matrices, the solving procedure can be accelerated. For implementing ...
