Treatement of Primary Coolant in NPPS – Operation Cost of Evaporator and Reverse Osmosis System

Popis výsledku v původním jazyce

Drained primary coolant from nuclear power plants containing boric acid is currently treated in the system of evaporators and by ion exchangers. Because their operation is expensive, reverse osmosis was suggested as an alternative technology. A pilot-plant unit of reverse osmosis was implemented and tested in Temelín nuclear power plant (NPP). The results of the tests performed in Temelín NPP were used to suggest a configuration of and operation conditions for a multi-stage semi-batch reverse osmosis system, which could be used in NPPs for the treatment of the drained primary coolant. Based on the data obtained during tests performed in Temelín NPP, we calculated operation cost of evaporator system and compared it with the operation cost of the suggested multi-stage semi-batch reverse osmosis system. Maximally three-stage reverse osmosis system was taken into account. The operation cost was calculated for the treatment of 1m3 of the drained primary coolant, which was concentrated to 40 g/l of boric acid, because such a solution can be recycled back in the NPP.
