Post Doc Research Associate - Cement Materials Science
Full/Part Time: Full-Time
The Radiological Materials and Detection Group (RMDG) in the Nuclear Science Division at PNNL is seeking two (2) individuals with a materials science, civil engineering or chemistry background with an interest in conducting applied research related to the treatment and immobilization of radioactive wastes. The RMDG is conducting research in waste form development and characterization for current and future radioactive waste immobilization and disposal.
This effort is focused on technology development of waste form formulations for immobilization of various types of nuclear wastes. Waste forms of interest particularly include cementitious and other materials formed at low temperatures. The candidate will assist in the planning of experiments, writing of test plans, production of test samples, performing of experiments, and writing of reports and papers. The candidate will support research efforts as part of a multi-disciplinary scientific team contributing to ongoing technical activities. The results will be prepared for technical reports and for journal publication. General activities include: preparing specimens, characterizing them, examining the data, compiling results and presenting findings at regular team meetings.
The waste forms will be characterized with respect to formulation, processing and final waste form properties. Analysis methods used may include rheology, calorimetry, ultrasound wave reflection techniques, chemical leaching studies, X-ray diffraction, scanning electron microscopy, and optical microscopy. Additional analysis methods would focus on physical characterization (e.g., flexural, compressive & tensile strength, permeability, hydraulic conductivity, etc.) Analysis methods may also include rheology, calorimetry, ultrasound wave reflection techniques, chemical leaching studies, X-ray diffraction, scanning electron microscopy, and optical microscopy
Candidate must be familiar with standard chemical laboratory operating procedures and standard analytical techniques. The candidate must be willing to learn and employ safe techniques for handling hazardous materials. The candidate will be required to maintain laboratory records and to implement and follow quality assurance procedures.
The post-doc position is planned for 1 year.
