SUMMARY
Structural Integrity brings decades of hands-on experience to Pressurized Water Reactor (PWR) water chemistry, helping nuclear plants protect long-term asset health while controlling operating costs. Our chemists and engineers work alongside station staff to optimize primary and secondary chemistry — from resin performance and chemical injection strategies for amine, zinc, PAA, and oxygen scavengers, to condensate polishing troubleshooting and sampling reduction evaluations that ease technician workload without sacrificing monitoring. Source term evaluations help reduce dose and sharpen outage performance, and our support extends well beyond the reactor to stator cooling, open and closed cooling water, service water, and liquid radwaste processing, as well as license renewal and extended power uprate projects.
Because lasting improvement depends on the people running the plant, we also deliver PWR operational chemistry training led by industry-recognized experts. Courses cover primary and secondary chemistry, hideout return, resin fundamentals, primary-to-secondary leaks, advanced troubleshooting, and more, and can be tailored to your station’s needs.
Chemistry rarely stands alone at an operating station, so our work sits inside a broader suite of operational support services. SI’s radiation management team performs ALARA and source term assessments, reviews the operational chemistry and material characteristics that drive source term, evaluates Standard Radiation Monitoring and Characterization (SRMC) dose rate data, and applies zinc surface modeling to predict future outage dose rate behavior. Our emergency preparedness specialists support effluent radiation monitoring and monitor replacements, assess dose assessment programs against industry best practices, and help develop the radiological inputs behind EP drills and Protective Action Recommendations.
Whether you need on-site help during an outage, a remote second opinion, or a customized long-term program, Structural Integrity offers a proactive partnership built on technical precision.
