COLUMBIA GENERATING STATION REQUEST TO IMPLEMENT 21SI-30 ADDRESSING USE OF SUBSEQUENT ASME SECTION Xi EDITION AND ADDENDA FOR CODE CATEGORY B-P Enclosure I Page 1 of 2 10 CFR 50.55A REQUEST NUMBER 21SI-30 Proposed Use of Subsequent ASME Code Edition and Addenda In Accordance with 10 CFR 50.55a(g)(4)(iv)
- 1.
ASME Code Component(s) Affected All Code Class 1 pressure retaining components
- 2.
Applicable Code Edition and Addenda
Columbia uses ASME Section XI 1989 edition with no addenda. Columbia is in its second inservice inspection interval, third inspection period.
- 3.
Proposed Subsequent Code Edition and Addenda and Portion ASME Section Xl 2001 Edition, 2003 Addenda, Table IWB-2500-1, Examination Category B-P and all related requirements, incorporated by reference in 10 CFR 50.55a(b) (Federal Register notice 69 FR 58804, October 1, 2004).
- 4.
Related Requirements When using portions of later editions and addenda of the Code, all related requirements including limitations identified in 10 CFR 50.55a are to be met. The following discussion identifies the related requirements that will also be used when implementing Examination Category B-P.
10 CFR 50.55a, Federal Register 69 FR 58804 Three limitations are identified in 10 CFR 50.55a(b)(2) for pressure testing.
- 1. (xx) - This paragraph defines hold times for Code Class 2 and 3 system leakage tests. This is not applicable since this request applies to Code Class 1 pressure retaining components.
- 2. (xxvi) - This paragraph defines pressure testing of mechanical joints during repair and replacement activities. This request does not include repair and replacement activities so this limitation is not applicable.
- 3. (xxvii) - This paragraph addresses insulation removal when pressure testing Code Class I borated systems. Columbia is a boiling water reactor and does not have Code Class I borated systems, so this limitation is not applicable to this request.
COLUMBIA GENERATING STATION REQUEST TO IMPLEMENT 21SI-30 ADDRESSING USE OF SUBSEQUENT ASME SECTION Xi EDITION AND ADDENDA FOR CODE CATEGORY B-P Enclosure I Page 2 of 2 ASME Section Xl The following related requirements from the 2001 Edition, 2003 Addenda, would be implemented as applicable to Examination Category B-P:
