Attachment Request to Implement Subsequent Edition of ASME OM Code ISTC-5222 and Mandatory Appendix II ASME Code Component(s) Affected All ASME Class 1, 2, and 3 check valves that are included in the QCNPS IST Program.
Applicable Code Edition and Addenda
ASME OM Code 1998 edition through 2000 addenda.
Proposed Subsequent Code_ Edition and Addenda (or Portion)
ASME OM Code 2004 edition, Section ISTC-5222, "Condition-Monitoring Program," and Mandatory Appendix II, "Check Valve Condition Monitoring Program." The 2004 edition of the ASME OM Code was incorporated by reference into 10 CFR 50.55a(b)(3) by 73 FR 52729.
EGC will apply these portions of the subsequent edition of the ASME OM Code to all ASME Class 1, 2, and 3 check valves that are included in the QCNPS IST Program.
Related Rectuuirements 10 CFR 50.55a(f)(4)(iv) states : "Inservice tests of pumps and valves may meet the requirements set forth in subsequent editions and addenda that are incorporated by reference in paragraph (b) of this section, subject to the limitations and modifications listed in paragraph (b) of this section, and subject to Commission approval. Portions of editions or addenda may be used provided that all related requirements of the respective editions or addenda are met."
As stated in 73 FR 52729, the "...revision to 10 CFR 50.55a(b)(3) incorporates by reference the 2004 Edition of the ASME OM Code subject to no new modifications or limitations." The existing limitations and modifications that are applicable to Mandatory Appendix II are described in 10 CFR 50.55a(b)(3)(iv), "Appendix Il."
10 CFR 50.55a(b)(3)(iv)(D) requires that the applicable provisions of subsection ISTC must be implemented if the Mandatory Appendix II condition monitoring program is discontinued.
For check valves that are removed from the QCNPS conditioning monitoring program, or in the case of discontinuation of the QCNPS condition monitoring program, EGC will implement the applicable provisions of Subsection ISTC of the ASME OM Code, 2004 edition.
