Moderator Flow Simulation Around Calandria Tubes of Candu-6 Nuclear Reactors

Development of an automated chemistry control system for secondary coolant circuits in CANDU nuclear power reactors

Inspection of CANDU Reactor Pressure Tubes Using Ultrasonics

Fuel channel pressure tubes are critical components of the CANDU reactor core which require periodic inspection to demonstrate continued fitness for service. Ontario Power Generation; Inspection & Maintenance Services Division has been operating a variety of inspection systems to perform volumetric and surface nondestructive examinations of the pressure tubes. Since the early days, ultrasonics ...

Simulation of turbulent flow around cylinders

Statistical flow modelling does not provide enough detail for many flows of engineering relevance in which unsteadiness is a central feature. This applies particularly to bluff-bodies and assemblies comprising bluff components for which the resolution of peak forces, unsteady loading, acoustics and fatigue are of interest as part of the design process. An example application which has been stud...

Safety of Nuclear Reactors

Nuclear reactors have, during the first twenty years of their existence, achieved an impressive safety record, possibly exceeding that of any comparable industry. As revealed in apaper byHenriB. Smets of the European Nuclear Energy Agency, there have been recorded during this period of time but six fatalities and less than 30 persons seriously irradiated from reactor accidents. Three of the fat...

Nuclear Weapons and Nuclear Reactors

This report addresses the tenuous link between nuclear power reactor development and the proliferation of nuclear weapons, particularly with respect to possible terrorist exploitation. Arguments are presented that contradict the popular image of nuclear weaponry as a "basement project". 4 CONTENTS
