Job Description

The Low Active Effluent Management Group (LAEMG) Strategy and Technical Team within Spent Fuel and Effluent Management (SF&EM) are offering an exciting opportunity to move into a new role. Applications are welcomed from individuals currently within the technical profession with relevant experience.

The LAEMG Plant Facing Technical Team provide technical support to a wide variety of facilities including the Enhanced Actinide Removal Plant (EARP), Solvent Treatment Plant (STP), Segregated Effluent Treatment Plant (SETP), Salt Evaporator and Medium Active Storage (SEMAS) and Waste Packaging and Encapsulation Plant (WPEP). The support provided to the facilities is broad with opportunities to get involved in underpinning changes to operations, conducting technical investigations and assessing plant performance.

It is an interesting time to join LAEMG Technical with work underway to redefine the operational philosophy of the facilities in the new era of post reprocessing. The team provide technical underpinning to the continued operation of the LAEMG facilities. Opportunities also exist to provide technical support to the delivery of a range of studies as well as providing underpinning assessments for Post Operational Clean Out (POCO) and Initial Decommissioning (ID) of the LAEMG facilities.

Successful applicants will have the opportunity to solve novel and challenging technical issues within the SF&EM directorate and be at the forefront of defining and implementing new approaches to effluent management.
