Dear Dr. Coughlin:
SUBJE CT: SECONDARY WATER CHEMISTRY CONTROL (Marble Hill)
In late 1975 we incorporated provisions into the Standard Technical Specifi-cations (STS) that required limiting conditions for operation and surveillance requirements for secondary water chemistry parameters.
The proposed Technical Specifications for your plant (s), as well as for other Pressurized Water Plants that have been issued an Operating License since 1974 or are now under review for an Operating License, contain either these provisions or a requirement to establish these provisions after baseline chemistry conditions have been detemined. The intent of the provisions was to provide added assurance that the operators of newly licensed plants would properly monitor and control secondary water chemistry to limit corrosion of steam generator tubes.
- n a nunber of instances the Technical Specifications have significantly restricted the operational flexibility of some plants with little or no benefit with regard to limiting corrosion of steam generator tubes.
Based on this experience and the knowledge gained in recent years, we have concluded that Technical Specification limits are not the most effective way of assuring that steam generator tube corrosion will be minimized.
Due to the complexity of the corrosion phenomena involved and the state-of-the-art as it exists today, we believe that, in lieu of Technical Specifications, a more effective approach would be to institute a license condition that requires the implementation of a secondary water chemistry monitoring and control program containing appropriate procedures and admin-istrative controls.
The required program and procedures would be developed by the licensee (or applicant) with any needed input from their reactor vendors or other consultants, and thus could more readily account for site and plant-specific factors that affect chemistry conditions in the steam generators.
In our view, plant operation following such procedures would provide assurance that licensees would devote proper attention to controlling secondary water chemistry, while also providing the needed flexibility to allow them to deal more effectively with any of f-normal conditions that might arise.

Dr. James Coughlin August 1,1979 Consequently, we request that you submit within 60 days your proposed secondary water chemistry program which will be referenced in a condition to your operating license and will replace any preposed Technical Specifications on secondary water chemistry. A model license ccndition is enclosed. We have concluded that such a license condition, in conjunction with existing Technical Specifications on steam generator tube leakage and inservice inspection, would provide the most practical and comprehensive means of assuring that steam generator tube integrity would be maintained.
If you have any questions, please contact us.
Sincerely, MN/W wL. S. Rubenstein, Actf ng Chief Light Water Reactors Branch No. 4 Division of Project Management
