Experimental work part 1: THe ragged Edge of Disaster

Our group has had some success in accessing time at experimental facililies as part of the National Nuclear User Facilities (NNUF) funding calls. One of these planned experiments is for time at the Bangor University Fusion Fabrication Facility (BUFFF) to study thermo-mechanical parameters, sintering parameters and hot corrosion.

We are also on the knife edge of making sure we have enough samples since we are waiting on other sample fabrication for another project that is subject to delays. So the risk of experimental work is not just contending with delays but also delays from other sources.

This is why contingency is critical when planning for experimental work - it is amazing how quickly the time can evaporate when you have to use it.

The Inaugural Entry – the life and times of the Radiation Dense Materials Group

Writing about web page

Welcome to the Radiation Dense Materials Group Blog. This blog will showcase the latest research from this group alongside how the research came to be with notes and photos of facilities, locations and conference trips. This will give people an insight into how research takes place on a day-by-day basis and on how many steps it takes to get to where you want to be.

The Radiation Dense Materials group aims to sythesize, study and develop novel concept radiation dense materials with the initial aim of making compact radiation shielding for fusion reactors and to make practical fusion power generation possible by 2030. It is envisaged that this will only be one such application for radiation dense materials when considering the need to expand the nuclear sector as a carbon-free power source.

Nuclear fusion has the potential to be a safe, effective carbon-free power source but has been limited in part by the lack of materials that can both attenuate radiation effectively and withstand the extremes of temperature expected within a power-generating fusion reactor. The plasma-facing component is expected to withstand temperatures up to 1000oC during normal operation. Superconducting magnets require cryogenic cooling (<77K), both of which would be seperated from each other by the shielding/coolant/Tritium blanket by little more than 1-2 m in a compact spherical tokamak. The initial cWC-RSB concept aims to be able to satisfy both radiation shielding and mechanical aspects with respect to this application.

This blog aims to be as interactive as possible and to give people an insight into how scientific research takes place behind the scenes.
