- 2. Communications report between H. Mentel (G&H), N. Williams (Cygna) and L. Weingart (Cygna), June 20, 1984 Dear Mr. Ballard Cygna has received and reviewed Gibbs & Hill's response concerning welded attachment stresses in break exclusion zones (Reference 1). As noted in the response, only the membrane portion of the local stress was included in the G&H re-evaluation of those attachments located in break exclusion zones. It is Cygna's position that local bending stresses should be included as well. The basis for this position is as follows:
The Class 2 criteria in MEB 3-1 permit break exclusion zones if the primary (equation 9) and secondary (equation
- 10) pipe st-esses meet certain limits. The fact that HEB 3-1 does in6end the primary, secondary and fatigue effects to be considered is evident by reviewing the Class 1 criteria. For Class 1, HE8 3-1 limits the equation 10 (primary plus secondary) pipe stress to 2.4 Sg and the fatigue usage factor to 0.1. Stresses above these limits require break postulation. The intent of MEB 3-1 is, therefore, to limit the potential for crack formation (i.e., limit fatigue). To determine fatigue stresses, one must consider the total stress at a point, not just the primary effects. This is apparent from the Class 1 break 7l) a)

SitVKES Mr. R. E. Ballard June 27, 1984 :
Page 2 criteria. Finally, MEB 3-1 has effectively stated that secondary / fatigue effects should be considered for Class 2 by including equation 10, which limits both secondary and fatigue stresses for Class 2. Therefore, when welded attachments are present, the total stress (local membrane plus bending) should be considered in order to meet the intent of HEB 3-1.
We would like to discuss this interpretation with you as soon as possible.
