Mohammed Adeel Shaikh, North West & North Wales
Adeel is currently working as a Graduate Consultant in Materials and Structural Integrity at Amec Foster Wheeler, prior to which he graduated from the University of Manchester with an MSc in Nuclear Science and Technology (2013) and a BSc in Materials Science and Engineering (2012). In his current role he provides Independent Nuclear Propulsion Assessment on materials and structural integrity related issues within the context of nuclear safety. In addition, he has been involved in the GDA for the UK ABWR for Hitachi-GE and also testing of zirconium in static auto claves utilising the SEM for imaging and oxide thickness measurements.
Adeel is also a STEM ambassador and has taken part in open days and STEM events to promote nuclear technology and encourages children and teenagers to pursue careers in STEM subjects.
Accident tolerant fuel cladding for LWR applications
The nuclear accident at Fukushima Daiichi in 2011 highlights the need to develop accident tolerant fuel cladding for Light Water Reactors (LWRs) in the event of a Loss of Coolant Accident (LOCA). Although zirconium alloys have largely been used, the event at Fukushima has focused the industries' attention on preventing this type of accident ever happening again, especially since the reputation of the nuclear industry is very quickly damaged by such events.
This lecture will discuss three options for accident tolerant cladding including advantages and disadvantages; Molybdenum, Fe-20Cr-5Al and SiC Composite cladding. In conclusion, SiC composites are seen as the most attractive when compared to Zr as SiC has a lower neutron capture cross-section, is chemically more stable, has a higher strength at elevated temperatures and has better resistance to radiation damage.
