A plant operating condition setting support system for supporting the setting of an operating condition of a plant that performs a process formed by devices includes: control devices that subject controlled devices to feedback control respectively; and an operating condition setting support device that provides integrated support for the setting of the control devices, which perform feedback control tasks respectively and independently. The operating condition setting support device includes: a measured value multiple acquisition unit that acquires measured values indicating states of the controlled devices, respectively; and a control device adjustment parameter determination unit that determines, based on the measured values acquired, control device adjustment parameters used by each of the control devices to determine manipulation variables for control that should be input to the controlled devices, according to a policy learned by deep reinforcement learning.

By using a boric acid-resistant anion exchange resin as the anion exchange resin used in a demineralizer that purifies the primary cooling water in a pressurized-water reactor power plant, even when a boric acid-containing primary cooling water is brought into contact with the anion exchange resin disposed in the demineralizer, the generation of breaking or cracking in the anion exchange resin can be prevented.
