SUMMARY:The Design of Small Modular Reactor (SMR) Cores for Civil Nuclear 
 Marine propulsion - Syed Bahauddin Alam (University of Cambridge)

DESCRIPTION:In an effort to de-carbonise commercial freight shipping\, the
 re is growing interest in the possibility of using nuclear propulsion syst
 ems. Reactor cores for such an application would need to be fundamentally 
 different from land-based power generation systems\, which require regular
  refuelling\, and from reactors used in military submarines\, as the fuel 
 used could not conceivably be as highly enriched. Nuclear-powered propulsi
 on allows ships to operate with low fuel costs\, long refueling intervals\
 , and minimal emissions\; however\, currently these systems remain largely
  confined to military vessels. This research project undertakes computati
 onal modelling of possible reactor core designs for this application with 
 a view to informing design decisions in terms of choices of the fuel compo
 sition\, materials\, core geometry and layout. Computational modelling usi
 ng appropriate reactor physics\, thermal hydraulics etc. Codes are used fo
 r this project.\n\nMotivated by growing environmental concerns and anticip
 ated economic pressures\, the overall goal of this study is to examine the
  technological feasibility of expanding the use of nuclear propulsion to c
 ivilian maritime shipping and to identify and propose promising candidate 
 core designs. This project introduces Thorium based fuel for the soluble-b
 oron-free small modular reactor (SMR) core design which incorporates the f
 eatures of long core life and high power density utilizing low uranium enr
 ichment.
