Subject:

Arkansss Nuclear One - Units 1 and 2 Docket Nos. 50-313 and 50-368 License Nos. DPR-51 and NPF-6 Subsequent Information to I E Bulletin 79-24 (File: 1510.1 and 2-1510.1)

Gentlemen:

In our response to I E Bulletin 79-24, dated October 31, 1979, we identified the Arkansas Nuclear One-Unit 2 refueling water tank overflow line as being a possible freeze ha:ard. Subsequent evaluation has revealed that this is not the case. The overflow line in question is adequately protected from free:ing for the following reasons:

1) The temperature of the water in the tank is maintained above 70 F.
2) There is no water in the overflow line unless the tank is over-filled.
3) The overflow line is 13 inches in diameter.

Thus, no modifications will be made to the overflow line for freeze protection purpos es .

Very truly yours, 0L69 f Sn David C. Trimble Manager, Licensing DCT:DEJ:bjm gg 4
