Description
In the CANDU reactor, the fuel and pressurized coolant are contained in Zr-2.5Nb pressure tubes that are joined to stainless steel end fittings by rolled joints. A Zircaloy tube surrounds the pressure tube, and the annular space between the tubes contains a recirculating gas. If a leak develops in the pressure tube, it is detected by monitoring the moisture in the annulus gas and the appropriate actions taken by the operators. This leak-before-break (LBB) capability is a defense in depth used in CANDU reactors to avoid unstable fracture of the pressure tube. Recent advances in the experimental data used in LBB assessments is presented and discussed
