Dear Yir. Dolan:
In late 1975 we incorporated provisfons. into the Standard Technical Specification,(STS) that required limiting conditions for operation and surveillance requirements for secondary water chemistry parameters.
The Technical Specifications for your plant(s),
as well as all other Pressurized'ater Reactor plants that have been.issued an Operating License since 1974,,
either contain these provisions, or a requirement to establish these'rovisions after baseline chemistry conditions have been determined.
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 stean generator tubes.
In a number of instances the Technical Speciffcations have sirjnificantly restr'feted the operational flexibilityof some plants with little or no benefit ufth regard to limiting corrosion of steam generator tubes.
Based on 'this experience, and the knowledge gained in recent years, we have concluded that Tectinfcal Specification limits are not the most effective way of assuring that stean 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 lfeu of Technical Specifications,'
more effective approach would be to institute
- a. license condition that requires the implementation of a,secondary water chemistry-monitorfng and control program containing appropriate procedures and adminfstrative controls.
A t<odel License Condition that-is acceptable to the staff-for this purpose is enclosed.
The required program and procedures would be developed by the licensees, with any, needed input
,ram their reactor vendors or other consultants, and thus could,more readily account for site and plant specific factors that affect cheraistry conditions in the stean generators.
In onr vien, /d4 g such a license condition would provide assurance that licensees would devote proper attention.to contro11ing secnndary IIater chenistry, Ivhile also providi'ng the needed flexibility to allow then to more effectively NRC PORN 518 (976) NRCM 0240

If you previously sub~itted an application for a license amendment concerning stean generator monitoring requirements prior to harch 22, 1978, that has yet to be issued by the HRC, you need not remit a fee
,for the license amendment requested by this letter. If you have not submitted a licen'se amendment request prior to Harch 22, 1978, you should remit a Class III fee with your application.

Dear Mr. Dolan:

) that required limiting conditions for operation and surveillance requirements for secondary water chemistry parameters.
The Technical Specifications for your plant(s),
as well as all other Pressurized I ater Reactor plants that have been issued an Operating License since 1974,
~
either contain these provisions, or a requirement to establish these provisions after baseline chemistry conditions have been determined.
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.
In a number of instances the Technical Specifications have significantly restricted the operational flexibilityof 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 administrative controls.
A Model License Condition that is acceptable to the staff for this purpose is enclosed.
The required program and procedures would be developed by the licensees, 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, such a license condition would provide assurance that licensees would devote pr oper attention to controlling secondary water chemistry, while also providing the needed flexibilityto allow them to more effectively deal with any off-normal conditions that might arise.
Moreover,"
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.
