Subject:
Interim Report of Potential 10CFR50.55(e) Item on overpressurizing Primary Containment Pipe Penetration Bellows
(#85)
Dear Mr. Keppler:
On December 13, 1982, Detroit Edison's Mr. D. Ferencz, Acting Supervisor-Construction Quality Assurance, telephoned Mr. H. Wescott's office of NRC Region III to report on a potential problem with overpressurizing primary contairment pipe penetration bellows at the Fermi 2 site.
This report was made concerning possible damage to the Primary Containment pipe penetration bellows as a result of overpressurizaticn during preopera-tional testing. The volume between the inner and outer bellows of each pipe penetration was pressure tested at 56.5 PSIG according to an approved procc-duru. A review of the manufacturer's documentation (Tube Turns) revealed that the test pressure should not exceed 35 PSIG.
Detroit Edison Engineering is evaluating this nonconforming condition.
Another report on this item, either interim or final, is scheduled to be sent on orbefore May 12, 1983. If you have questions concerning this-matter, please contact Mr. G.M. Trahey, Assistant Director-Project Quality Assurance.
Very truly yours, w_.
