(a) Construction Permits CPPR-135 and CPPR-136, Docket Nos. 50-443 and 50-444 (b) PSNH Letter, dated December 3, 1982, " Response to Mechanical Engineering Branch RAI 210.89," J. DeVincentis to G. W. Knighton
Subject:
Supplemental Response to Mechanical Engineering Branch RAI 210.89
Dear Sir:
Recently, it was brought to our attention that our response [ Reference (b)) to the Mechanical Engineering Branch (MEB) RAI 210.89, " Evaluations of Tees or Branch Connections in Class 1 Piping" did not provide sufficient technical detail to support our conclusion that ASME Code requirements have been met for evaluation of tees or branch connections in Class 1 Piping. The concerns, which were the result of your staff's and contractor's review of our response, are outlined on Attachments 1 and 2 of this letter.
On September 30, 1985, a conference call was held with representatives of your Staff, their consultants, Westinghouse and New Hampshire Yankee personnel to discuss these concerns.
In our discussions, we indicated that the details which were identified and those concerns are primarily within the Class 1 Stress Reports and/or other reference material. It was mutually concluded that staff's and contractor's concerns would be satisfactorily recognized and resolved by the inclusion of the " Requested Specific Data" into the Class 1 Stress Reports via reference and/or by attachment (s) to the Class 1 Stress Reports.
We believe that the above adequately addresses the concerns and that it ensures the code requirements have been incorporated into our Class 1 Stress Reports. This will be done for Class 1 Stress Reports furnished by either' Westinghouse or United Engineers and Constructors which will be completed before core load. Therefore, based on our discussions and statement above, we consider this RAI and issue resolved.
