coolant chemistry is maintained and monitored as described in the BTP 5-1, “Monitoring of Secondary Side Water Chemistry in PWR Steam Generator,” (2) the secondary water chemistry requirements in the latest revisions of the Standard Technical Specifications, NUREG-1430, “Standard Technical Specifications - Babcock and Wilcox Plants,” NUREG-1431, “Standard Technical Specifications - Westinghouse Plants,” and NUREG-1432, “Standard Technical Specifications - Combustion Engineering Plants,” are incorporated into the facility’s Technical Specifications (the secondary water chemistry program in the Standard Technical Specifications meets the requirements of 10 CFR 50.36, “Technical Specifications,” and (3) the chemical additives that limit the steam generator’s susceptibility to corrosion are such that any degradation to which the steam generator remains susceptible can be managed through the inservice inspection program. The operating environment (temperature, pressure, and flow) includes important variables that must be considered in evaluating the effectiveness of the chemical additives in limiting the steam generator’s susceptibility to corrosion. The onsite cleaning and cleanliness controls of the steam generator are acceptable if they meet the regulatory provisions of RG 1.28, consistent with the requirements of Criterion XIII of Appendix B to 10 CFR Part 50. 6. Provisions for Accessing the Secondary Side of the Steam Generator Corrosion products (including deposits and sludge) and other contaminants can accumulate in the secondary side of the steam generator. For example, corrosion products and contaminants have been observed along the length of the steam generator tubes, in the crevice between the tube and the tube supports, and at the top of the tubesheet. Depending on the nature of these corrosion products and contaminants, degradation of the tubes (or other components) can occur. Because this degradation could lead to degradation of
