Dear Mr.Denton:

Carolina Power 6 Light Company (CP&L)hereby submits additional information concerning the interaction of Non-Category I piping with Category I piping at the Shearon Harris Nuclear Power Plant.This information is submitted in response to Safety Evaluation Report Confirmatory Item 5 from the Mechanical Engineering Branch.If you have any questions or require additional information, please contact me.Yours very truly, S.R.immerman Manager Nuclear Licensing Section JHE/pgp (596JHE)Attachment cct Mr.B.C.Buckley (NRC)Mr.G.F.Maxwell (NRC-SHNPP)

A review of 1141 piping stress isometrics identified 220 seismic/non-seismic interface anchors.104 of these anchors were found to be acceptable as designed-60 large bore and 44 small bore.18 anchors failed the pipe yielding moment analysis-12 large bore and 6 small bore.These 18 anchors had vertical supports only on the non-seismic side of the anchor.Lateral restraints have since been designed on the non-seismic side of these anchors.such that criterion 2 is satisfied for the 6 small bore anchors and criterion 3 is satisfied for the 12 large bore anchors.The remaining 98 anchors-7 large bore and 91 small bore had no supports designed on the non-seismic side of the anchors when the study was conducted.

These designs are currently ongoing and are being designed to satisfy the criterion 2 (for small bore)and criterion 3 (for large bore).The effort is currently approximately 90%complete.CP&L considers this item closed.
