Nuclear - Boric Acid Recovery:
Recreate baseline design information, process development and design of new plant.
Boric acid is used as a moderator in pressurised water reactors. Its recovery process had not changed for over 50 years due to a reluctance to modify “tried and tested” designs. As a result, limited original design information was held on file and expertise had been lost. A new fleet of power stations had prompted a review of the design, with the aim of improving its efficiency.
Establish baseline information and process requirements.
Develop a comprehensive simulation model that handles electrolytes and dissolved gases.
Replicate existing process and make virtual improvements using the model.
Size distillation column and heat exchangers using rigorous modelling methods.
Document all work to support wider design work.
