Understanding physical properties of settled Zirconium Molybdate (ZM) solid beds

Tender description

Zirconium Molybdate (ZM - ZrMo2O7(OH)2(H2O)2) is a solid which forms, from conversion of caesium phosphomolybdate in the presence of zirconium, during storage of highly active liquid waste generated from nuclear reprocessing operations. NNL is requiring RFI responses for a supplier to investigate the formation of yield strength in settled ZM beds and determine parameters that impact the experimentally observed differences in yield stress. The task should aim to determine a reason for the behaviour and potential mechanism. Furthermore, it would be advantageous if the conditions which promote unwanted high yield stress is identified for nitric acid-based solutions. Responses to the attached RFI document should be sent to david.brown@uknnl.com before 17:00pm 8th March 2024. Additional information: Responses to the RFI should be sent to david.brown@uknnl.com before 17:00pm 8th March 2024.
