Haleema is a Criticality Consultant with an MSc in Nuclear Decommissioning and Waste Management supplementing her BSc in Physics. Haleema has been involved in project work for the Safety Case Team at UUK, including a criticality transport assessment. She has built complex models in MCNP of nuclear waste storage, such as ponds and bunkers, and ran subsequent criticality calculations. When joining Cerberus Haleema completed a criticality project investigating a reactor built via. MCNP with multiple parameter variations. The criticality for each variation of parameterisation was used for analysis and training of a machine learning algorithm to create a criticality training tool, utilising Python, Jupyter and her data science skills. Since joining Cerberus Haleema has also completed a shielding assessment and subsequent report.
