The MERLIN programme: Pt. 3
Description
The MERLIN (Multi-Rod Electrically Heated Rig for LOCA Investigation) rig at Springfields Laboratory (SL) was designed to investigate vibration and clad ballooning in a multi rod array during a postulated LOCA (Loss of Coolant Accident). The fuel pins were represented by electrically heated fuel pin simulators. The rig 'comprised' an upper Zircaloy clad test section approximately 1.5 m long and a lower, stainless steel clad, pre-heater section of similar length. This report describes the development and manufacture of 9.5 mm o.d. fuel rod simulators for both the upper and lower sections of the rig in order to perform a 6 x 6 thermal-hydraulic experiment (Bundle 'B').
