ng program of each individual plant. The applicant should meet EPRI NP-6239 as supplemented by Table 1, or equivalent appropriate guidelines, and incorporate the technical recommendations of the steam generator supplier. Any significant deviation from EPRI NP-6239, Table 1, or the supplier's recommendations should be noted and justified technically.74 Records should be made of the monitored item values, and in accordance with 10 CFR Part 50, §50.71(a) they shall and should be made available for audit and 75 inspection when deemed necessary. Each licensee as part of histhe annual operating report should include an 76 evaluation of the secondary side water chemistry program with an evaluation of the trends and a summary of the total time during the reporting period the various chemistry parameters were out-of-specification. d. For plants utilizing volatile chemistry: (1) The composition, quantities, and addition rates of additives should be recorded. Routine changes in these items should be reported under biannual FSAR update as required by 10 CFR Part 50, 50.71. However, 77 nonconservative changes, i.e., relaxation in sample frequency, or changes in impurity limits, shall be submitted to NRC for approval before the 78 change is implemented. DRAFT Rev. 3 - April 1996 5.4.2.1-16 (2) The electrical conductivity and the pH of the bulk steam generator water and feedwater should be measured continuously. Assurance should be provided that the sample taken at the blowdown is typical of the bulk steam generator water and that there is a minimum bypass between the feedwater inlet and the blowdown sampling point. (3) For once-through steam generators, the pH and electrical conductivity at the coolant inlet should be measured continuously. (4) Free hydroxide concentration and impurities (particularly chloride, ammonia and silica) in the steam generator water should be measured at least three times per week. e. For plants utilizing phosphate treatment: (1) The composition,
