Description

The MERLIN (Multi Rod Electrically heated Rig for LOCA INvestigation) rig at Springfields Nuclear Laboratories (SNL) is used to investigate the deformation behaviour of Zircaloy fuel rod cladding in a Pressurised Water Reactor (PWR) following a postulated large break loss-of-coolant accident (LOCA). This Report describes the components, instrumentation and assembly of a 6 x 6 cluster of electrically heated fuel rod simulators which can be subjected to temperature transients and bottom reflood in order to determine the thermal hydraulic characteristics of the rig.
