RE: ARKANSAS NUCLEAR Oht, UNIT h0. 1
- n August 1975 we sent letters to t.Fe majority of licensees who Ocerate Pressurized Water Reactors (PWRs) regarding the control of secondary water chemistry to inhibit corrosion of steam generator tubes. le letters requested the ifcensees to arcpose Technical Scecification changes to incorcorate limiting conditions for operation and surveillance requirements for secondary water chemistry parameters. Mcdel Technicai Specifications, which reflected the requirements contained in the Coctnission's 2tanda-d Technical Specifications (STS), were incluced for guidance.
Many licensees Ocjected to the Mcdel Technical Scecifications rincipaily on the basis that they could unnecessarily restrict plan: Operation. The majority of these licensees submitted alternative accroaches that were directed more : ward monitoring and record keeping rather than s:eci'ic limits on chemistry ::arameters. At the time of our request, we rac:,gn"'ed that a major disadvantage of the Technical Specifications was a Octentiel decrease in operational flexibility, but cur request was :ctivatec by an overriding concer7 fcr steam generatcr tuce integrity. Cur cbj ective.<as to :rovide added assurance that licensees would peccerly monitor and control secondary water chemistry Oc Timit cceresion of steam gererator tuces.
Mcwever, based an One exxrience and kncwiecge gainec since. !975, we nave new concluded tha: Technical Specification limits wcult not :e the most effective way cf acccmplishing this cjective. ^ue ;0 the canplexity of the corrosion ;henccena involved, and tne s: ate-cf-the-art is it exists t: day, we believe :nat a more effective accreacn ould be
- institute a license c:ncition that requires One implementation of a seccndary water chemistry acnitoring and control crogram containing 1:::rocriate :r:cedures and acministrative controls. A Mccel License C0rcition tha is accectacle to the staf# for tni s cur;cse is enci: sed.

Arkansas Power & Lignt Cogany devote proper attention to controlling secondary water caemistry, while also provicing the needed flexibility to allow them ta core effectively deal with any off-normal conditions that might arise.
Moreover, we have concluced that such a license conditian, in conjunction with existing Technical Specifications on steam generator tube leakage ~and inservice inspection, would provide the nest practical and cogrehensive means of assuring that steam generator tuce integrity is maintained.
Consequently, we request that you submit a proposeo amencment to ycur license to incorporate the requirements of the enclosed Houel License Condition into the body of your license within 60 days.
If you previously submitted an application for a license amencr/ ant concerning steam generator monitoring requirercents prior to March 2'2, 1978, you neea not rer.
fee for the license amendment requested a
by this letter.
If you.. ave not submitted a license amendment request prior to Marcr. 22, 1976 you snould remit a Class 'II fee w"n your application.
If you nave any questlu.,, please contact us.
f40 furtner action will taun on any propoua Tecnnical Specifia: ion changes you may nave su',itted in response to our August 1976 request.
Sucn change requests w' I be considered withdrawn unless you express objections within 60 da, s.
Sincerely,
