Overview
In collaboration with the UK National Nuclear Laboratory this role will include the fabrication of active vitrified wasteform simulants. Following manufacture of uranium containing glasses the post holder will analyse their chemical and physical properties including glass transition temperature, viscosity and durability.
The post holder should have, or be close to completing, a PhD in materials or an appropriate physical science. They should have strong practical laboratory skills including thermal treatment (ideally glass making), aqueous phase analysis and solid state characterisation techniques. They will also require knowledge and experience of radioactive waste immobilisation in glass materials. This post would be ideal for a proactive researcher with good time management skills and independent working who can deliver project outcomes on time. They will also require excellent communication skills for liaising with industry partners throughout the project.
Main Duties and Responsibilities
* Manufacture uranium containing glasses of compositions defined by the industrial sponsors UKNNL
* Characterise these glasses to determine properties including their density, viscosity, glass transition temperature and durability.
* Follow ASTM standard protocols to conduct Soxhlet and PCT‑B durability tests ensuring high data quality and reproducibility.
* Conduct visual inspections of the glasses by light microscope and SEM
* Communicate findings both verbally and in writing to industrial sponsors UKNNL
* Ensure the timely completion of final and interim project reports
* Travel to UKNNL facilities (potentially including those in Cumbria) for project meetings if necessary.
* Coordinate and liaise with other members of the research group and collaborators over work progress.
* Plan and manage dissemination of project results.
* Assist the investigators in managing grant finances.
* Initiate necessary materials / equipment purchase requisition.
* As a member of staff you will be encouraged to make ethical decisions in your role, embedding the University sustainability strategy into your working activities wherever possible.
* Carry out other duties, commensurate with the grade and remit of the post.
