Dr Nicholas Bryan

Director, Centre for Radiochemistry Research

The main research area of my group is Environmental Chemistry, and in particular, the interaction of radionuclides with natural systems. Current projects involve the study of the interaction of these elements with natural colloids, including humic substances. Colloids have a high affinity for many pollutants, and can act as a vector for their migration in the environment. Lab experiments are used to study sorption and desorption mechanisms, and are backed up by work involving real samples from the field. In addition, we study the colloidal properties of humic substances, for example, the determination of molecular size, molecular weight distributions and colloid zeta potentials.

Other current work involves the study of the interaction of redox sensitive radionuclides, U, Tc, Np, and Pu, with natural and synthetic inorganic surfaces. Using data from laboratory experiments, mathematical models are developed, which are able to simulate the behaviour of radionuclides in the environment. These are used to make predictions about the probable extent of radionuclide migration, and hence, the environmental impact.

Group

Research Centre for Radwaste and Decommissioning

The RCRD is dedicated to research and training into the safe containment and disposal of radioactive wastes, the decommissioning of contaminated nuclear plant and the containment and remediation of radionuclides in the environment.

Centre for Radiochemistry Research

The Centre for Radiochemistry Research (CRR) was established in 1999 in a partnership with BNFL. It is unique in the UK, forming a national focus for radiochemistry research, and we are primarily interested in the chemistry of the radioactive elements, particularly Tc and the transuranic elements. Our research activities link closely to many aspects of the nuclear industry, from process chemistry to decommissioning, waste management and environmental impact.
