Mr. Walter Butler, Chief Licensing Branch 2 Division of Licensing Gentlemen:
SAFETY EVALUATION REPORT CONFIRMATORY ISSUE 1 HOPE CREEK GENERATING STATION DOCKET NO. 50-354 Pursuant to discussions with D. Wagner and R.
Li, the following information is being provided on the stresses imposed on the feedwater check valve hinge pin following a double ended break of the feedwater line outside contain-ment.
A manual elastic analysis was performed for the hinge shaft (pin) housing and shaft using the maximum angular velocity generated in the hinge arm analysis.
Since the stress levels for bending in the shaft housing and for shear in the shaft, as determined by this analysis, are consider-ably less than the allowable of 0.70 Su as specified by Appendix F, Table F-1322.2-1 of the ASME B&PV Code,Section III, it is concluded that the hinge shaft housing and shaft are acceptable.
Should you have any questions in this regard, please contact us.
Very truly yours, h
