Region III office telecopied data from their material sampling program that was not included in their transmittal to C F Braun on October 7. Copies of the six documents are attached. The

( identification of the documents and my comments are listed below.

ATTACHMENT 1 Letter dated November 19 from US NRC, C E Cornelius, 1 Page to C F Braun, W L Stiebe, transmittal letter for other attachments.

No comment.

ATTACHMENT 2 Sargent and Lundy Responses to NRC Region III " Questions 6 pages on EVAC System" Question 1 I agree with S & L's discussion of the

(]) effects of increased hardness of bolting material.

Although the reported hardness of 287'Brinell is well above the maximum of 241 allowed for A307 Grade A bolts, it is near the middle of the range of 248 to 331 Brinell for A325, High-Strength Bolts for Structural Steel Joints. A325 is a commonly specified bolting material when higher strength is required.

Questions 2 and 3. No comments.

ATTACHMENT 3 Results of Sample Analysis (56 samples) 4 pages My comments on the first 48 samples are contained in

{ my pink letter to you dated October 13.*

Samples 49 and 50 conform to the chemical requirements i for A575, Grade M1015, and are acceptable for use in accordance with ASTM A29, paragraph 4.3.1, because no misapplication is indicated.

Samples 51 through 56 are for A307 bolts and A563 nuts.

The results shown are within the specification "

requirements.

( *The first 48 samples are discussed in Section 5.3 MATERIAL and Appendix L of the final report.
