Abstract

As a result of a detailed review of the literary sources it was revealed that the effect of temperature on the ion exchange process is paid little attention nowadays.

Therefore, in the paper the authors first of all aimed to study thermal stability of ionites and to prove the importance of maintenance of temperature mode of the turbine condensate demineralization process at nuclear power plants.

Since the operator-technologist is responsible for prompt decisions regarding the period of ionite filters blocking at the power generating unit, his actions can not be considered as optimal.

Failure to maintain the process temperature conditions leads to ionite matrix destruction and loss of the ion exchange resin ability to ion exchange with other minerals of the NPP secondary circuit.

The authors developed an automatic system of temperature control of the block demineralization plant for filters operation control of the turbine condensate demineralization system. This system is implemented based on the Honeywell microprocessor technology using the Experion PKS software package. The system will help to avoid the ionite destruction, extend the operation term of ion exchange resins, reduce filter operation on the worn resins and avoid emission of mineral ions into the workspace of the second circuit.

Verification of the system was carried out using the information on the Khmelnitsky NPP current operation. The results do not exceed the standards and are acceptable for use
