RE: CRYSTAL RIVER, UNIT NO. 3 In late 1975 we...corporated provisions into the Standara 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 Water Reactor plai.ts that have been issued an Operating License since 1974, either contain these provisions, or a requirement to establisn these provisions after baseline chemistry conditions have been ceterminec.
The intent of the provisions was tu provide aadeo assurance that the operaton of newly licensaa plants woula properly monitor and control secondary water chemistry to limit corrcsion of steam generator tubes.
In a number of instances r.he Technical Specifications have signi ficantly restricted the operational flexibility of some plants witn little or no benefit with regard to limiting corrosion of steam generator tuces. Based on this experience,.and the knowleoge gained in recent years, we have concluded that Technical Specificatier. limits are not the most effective way of assuring that steara generater tuce corrosion will be minimizec.
Due to the cotplexity of the corrosion phenomena involved, and the state-of-the-art as it exists today, we believe tnat, in lieu of Technical Specificati]ns, a cure effective approach wcula be to institute a license condition tnat requires the irrplementation of a secondary dater chemistry monitoring and control program containing appropriate procecures ano aaninistrative controls. A Model License Conaition that is acceptaole 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 ano plant scecific factors that affect chemistry conditions in the steam generators.
In ou r vi ew,
such a license condition would provide assurance that licensees would devote proper attention to controlling secondary water chemistry, wnile also providing the needed flexibility to allow them to more effectively deal with any off-normal conditions that might arise. Moreover,-we nave concluded that such a license condition, in conjunction with existing Technical Specifications on steam ganerator tube leakage and inservice inspection, would provide the most practical and cororenensive heans of assuring that steam generator tuce integrity woulc be maintainea.

Florica Power Corporation Consequently, we reques+. that you submit a proposed amencment to your license to delete your existing Technical Specifications on seconaary water chemistry and to incorporate the require.ments of the enclosed Model License Condition into the body of your license within 60 cays.
If you previously submitted an application for a license araencment concerning steam generator monitoring requirements prior to narch 22, 1978, that has yet to be issued by the NRC, you need not remit a fee fcr the license amendment requested by this letter.
If you have not suomi+.ted a license amendment request prior to Maren '2,1978, you 4
should remit a Class III fee with your application.
If you have any questions, please contact us.
Sincerely, s~ y Vi G J v

i ENCLOSURE MOCEL LICE'iSE CONDITION SICONCARY '.4ATER CHE'il51 AY MONITCRING The licensee shall implement a secondary water chasistry scnitoring program to inhibit steam generator tube degradation. This prcgram shall include:
.l.
Identification of a sampling senedule for the critical parameters and control points for these parameters; 2.
Identification of the procedures used to quantify parameters that are critical to control coints; 3.
Identification of process sampling points; 4.
Procedure for the recording and management of data; 5.
Procedures defining corrective actions for off control point chemistry conditions; and 6.
A crocedure identifying the authority responsible for the inter-pretation of the data, and the sequence and timing of acainistrative events required to initiate corrective action.
