Subject:

Arkansas Nuclear One - Unit 1 Docket No. 50-313 License No. DPR-51 Proposed License Amendment /

Request for Additional Information Concerning Secondary Water Chemistry Gentlemen:

Please refer to your letter (1CNA088204) to Mr. William Cavanaugh III dated August 31, 1982, which requests a suitable proposed license condition and additional information concerning secondary water chemistry monitoring for Arkansas Nuclear One, Unit 1 (ANO-1). The following response and proposed amendment to the ANO-1 license is provided pursuant to your subject correspondence.

Item I:

The information you have provided is insufficient for us to evaluate the secondary water chemistry control program. Provide a summary of operative procedures to be used for the steam generator secondary water chemistry control and monitering program, addressing the following:

1. Sampling frequency for the critical chemical and other parameters and of control points or limits for these parameters for each mode of operation: normal operation, hot startup, cold startup, hot shutdown, cold wet layup; jMl l

2. Procedures used to measure the values of the critical parameters;

3. Location of process sampling points; 0.@

Nov:mbar 9, 1982 Mr. J. F. Stolz 2

4. Procedure for the recording and management of data;

5. Procedures defining corrective actions for off-control point chemistry conditions detailing time allowed at off-chemistry conditions; and

6. The procedures identifying (a) the authority responsible for the interpretation of the data and (b) the sequence and timing of administrative events required to initiate corrective action.

Response

The requested information necessary to respond to this item is ,

contained in Attachment 1 to this letter, which is a copy of AN0 Procedure 1000.42 entitled, " Steam Generator Water Chemistry-Monitoring - Unit One." This procedure addresses all of the above items directly, with the exception of Item I.3. In clarification of that Itera, the following information is provided.

Process samples and their sampling points are:

1. Feedwater Sample - Samples are obtained downstream of the demineralizer units;

2. Final Feedwater Sample - Samples are obtained downstream of the feedwater heaters and upstream of the steam generators;

3. S_ team Generator Sample - Samples are obtained from the :: team _

generators; and

4. Condensate Sample - Samples are obtained from the discharge of the condensate pumps, upstream of the demineralizer units.

Item II:

Verify that the steam generator secondary water chemistry control program incorporates technical recommendations of the NSSS. Any significant deviations from NSSS recommendations should be noted and justified technically.

Response

After reviewing NSSS vendor recommendations, two differences from those recommendations have been noted. The first difference involves the establishment of procedures for placing the feedwater heaters in wet layup. At ANO-1, only steam generator wet layup is covered by procedure. Although the feedwater heaters are initially placed in wet layup, this condition is t.ot maintained. The secondary system is recirculated through the demineralizers and condenser prior to startup and prior to bringing the steam generators back on line, thus insuring both steam generator and secondary chemistry integrity. We do not believe additional procedures are required.

Mr. J. F. Stolz 3 Novemb:r 9, 1982 The second difference identified pertains to the performance of chemical analysis for lead in the steam generators and secondary system. The procedure for performing this analysis is currently under ...

review.

Item III:

In addition to the secondary water chemistry monitoring and control program, we require monitoring of the steam condensate at the effluent of the condensate pump. The monitoring of the condensate is for the purpose of detecting condenser leakage. Verify that the steam condensate at the effluent of the condensate pump is monitored.

Response

As mentioned in the response to Item I, condensate samples are taken at the discharge of the condensate pumps. Condensate is continuously monitored via in-line analyzers for sodium content (which is primarily for leakage detection) and dissolved oxygen.

Item IV:

If demineralizers are used, explain how you prevent resin breakthrough into the steam generator.

Response

The Unit 1 condensate polisher units contain strainers which remove solid pieces of resin from the condensate effluent.

The proposed license amendment desired to formally implement the secondary water chemistry program for ANO-1 is submitted as Attachment 2 to this letter for your review and approval. Pursuant to the requirements of 10CFR170.22, we have determined our amendment request to require a Class III fee of $4,000, as it involves a single issue which does not require significant hazards determination. Accordingly, a check in the amount of

$4,000 is remitted.
