Docket No. 50-265
SUBJECT:
Fort Calboun Station Unit No. I - Request for Limited Use of the ZOO1 Edition, 2003 Addenda of ASME Boiler and Pressure VesseI Code Section XI Tor Examination of Cast Stainless Steel Piping Federal Register Notice 69 FR 58804 dated October 1, 2004 announced that the NRC had amended its regulations to incorporate by reference more recent editions of the American Society of Mechanical Engi t~ears (ASME) Boiler and Pressure Vessel Code. The amended regulations became effective on November 1, 2004. The revised 10 CFR 50.55a(b)(2) references ASME Section XI editions through the 2001 edition and the 2003 Addenda. Pursuant to 10 CFR 50.55a(g)(4)(i v) and NRC Regulatory Informatio~~
Summary (RIS) 2004-12, the Omaha Public Power District (OPPDI requests NRC staff approval to use the ASME Section XI 2001 Edition, 2003 Addenda for examination of cast stainless steel piping at Fort Calhoun Station Unit No. 1 (FCS).
There are no rclated requirements; as required per 1 OCFR50.5 5a(g)(4)(iv), Appendix I11 of the ASME Boiler and Pressure Vessel Code.Section XI, 3001 Edition, 2003 Addenda will be used in its entirety for the cast stainless steel piping at FCS for the fourth ten-year IS1 interval.
Appendix I11 has no requirements for a performance demonstration. but all the rules of Appendix 111 will be followed for the procedures, equipment, calibration, detection, recording, and evaluation of exaninations for welds in thc cast stainless steel piping at FCS.
Initial use of Appendix 111 will be during the current refueling outage. The hot and cold leg piping connecting the reactor coolar~t system to the two steam generators is cast stainless steel.
The welds to be examined are the hot and cold leg tie in welds for the two replacement steam generators. Each replacement steam generator ha one hot leg weld and two cold leg welds. The hot leg thickness is approximately 3.5 inches and the cold leg thickness is approximately 2.5 inches.
Employment with Equal Opporfunif?
