Bruce CANFLEX-LVRF Fuel Qualification
Main Article Content
Abstract
A low void reactivity fuel (LVRF) bundle has been developed to reduce void reactivity during a postulated accident, such as a large break loss-of-coolant accident. The LVRF bundles are intended for use in the Bruce Nuclear Generating Station (NGS) B reactors.
The verification activities include tests, analyses and assessments, or a combination of these, enveloping permitted operational and design
configurations. Credible fuel damage mechanisms or key performance
parameters are systematically evaluated individually and in combination, as appropriate.
This paper describes the detailed implementation of qualification activities demonstrating the mechanical integrity of the LVRF design, including irradiation performance, out-reactor tests and analytical assessments.
