t plate. Nuclear plant operators should start up the steam generators with "metal clean" surfaces. A method of confirmation such as photographing the inside of the steam generator should be undertaken after hot functional testing to confirm the "metal clean" condition. 5.4.2.1-15 DRAFT Rev. 3 - April 1996 3. a. In the FSAR, the applicant should describe implementation of a secondary water chemistry and monitoring program (in accordance with reference nuclear steam system supplier's recommended procedure) to inhibit steam generator corrosion and tube degradation. Applicants should meet EPRI NP-6239, "PWR Secondary Water Chemistry Guidelines," (Reference 2) as supplemented by Table 1, or equivalent appropriate guidelines. This program should cover the following 71 operational modes: (1) power operation (normal), (2) startup, (3) hot standby, (4) hot shutdown, and (5) cold shutdown/cold wet layup. Each of the above modes should be defined with regards to percent rated thermal power and approximate temperature range, Fahrenheit. 72 b. The secondary water chemistry monitoring and control program should include the following:(1)Iidentification of a sampling schedule for critical parameters 73 during each mode of operation and of acceptance control criteria for these parameters. The program should include as a minimum the control of pH, cation conductivity, free sodium, and dissolved oxygen. However, other parameters such as specific conductivity, chlorine, fluorine, suspended solids, silica, total iron, copper, ammonia, and residual hydrazine merit consideration. In plants having more than one steam generator, additives to each steam generator should be controlled separately. c. The Nuclear Regulatory Commission will review the secondary water chemistry control and monitoring 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
