Gentlemen:

Our letter of August 24, 1977, described a potential problem with regard to low lift-off force for certain containment tendons at Arkansas Nuclear One-Unit 1 (ANO-1). Our letter also noted a decrease in tensile strength of some wires withdrawn for testing and stated a review of these problems was underway. By letter dated November After 4,

1977, we forwarded the results of our review in report form.

reviewing our November 4,1977 report, Mr. D. K. Davis' letter of December 23, 1977 requested additional information in urder to complete your review, in accordance with your request, please find enclosed our responses to your questions.

Very,truly yours, h.
