32

Mitigation of defects by modification (A) The use of IWA-4340 of Section XI 2001 Edition through the 2010 Addenda, is prohibited.

(B) The use of IWA-4340 of Section XI 2011 Edition through the 2017 Edition may be used subject to the following conditions:

(1) The use of IWA-4340 to mitigate crack like defects or those associated with flow accelerated corrosion are prohibited.

(2) The design of a modification that mitigates a defect shall incorporate a loss of material rate either 2 times the actual measured corrosion rate in that pipe location (established based on wall thickness measurements conducted at least twice in two prior consecutive or nonconsecutive refueling outage cycles in the 10 year period prior to installation of the modification), or 4 times the estimated maximum corrosion rate for the piping system.

(3) The Owner shall perform a wall thickness examination in the vicinity of the modification and relevant pipe base metal during each refueling outage cycle to detect propagation of the flaw into the material credited for structural integrity of the item unless the examinations in the two refueling outage cycles subsequent to the installation of the modification are capable of validating the projected flaw growth. 33

Appendix III, Supplement 2

  • Incorporation of Code Case N-824 for ultrasonic testing examination of Cast Austenitic Stainless Steel
  • Applies the conditions that were imposed on N-824 in the 2018 ASME Code Case Regulatory Guide Rule Making

- (A) Instead of Paragraph 1(c)(1)(-c)(-2), licensees shall use a phased array search unit with a center frequency of 500 kHz with a tolerance of +/- 20 percent.

- (B) Instead of Paragraph 1(c)(1)(-d), the phased array search unit must produce angles including, but not limited to, 30 to 55 degrees with a maximum increment of 5 degrees.

34

Defect Removal

  • The use of the provisions for removal of defects by welding or brazing in IWA-4421(c)(1) and IWA-4421(c)(2) of Section XI, 2017 Edition may be used subject to the following conditions:

(A) The provisions of subparagraph IWA-4421(c)(1) shall not be used to contain or isolate a defective area without removal of the defect.

(B) The provisions of subparagraph IWA-4421(c)(2) shall not be used for crack-like defects.

35

Prohibitions and Restrictions on Use of IWB-3510.4(b)

- The NRC staff does not find Subparagraph IWB-3510.4(b) acceptable. For the prohibited materials specified in Subparagraphs IWB-3510.4(b)(4) and IWB-3510.4(b)(5), the NRC staff observed that in the technical basis document, there is no fracture toughness data associated with the weld and heat affected zone or there is no fracture toughness data to support exclusion of the fracture toughness requirements for these materials.

36

ASME OM Code Robert Wolfgang Division of Engineering Office of Nuclear Reactor Regulation 37

Specific OM Items of Interest in Proposed Rulemaking

  • Add 10 CFR 50.55a(f)(7) to require applicants and licensees to submit IST Plans and interim IST Plan updates related to pumps and valves, and IST Plans and interim IST Plan updates related to snubber examination and testing to NRC Headquarters, NRC Regional Office and NRC Inspector, based on planned deletion of submittal requirements from ASME OM Code
  • Amend 10 CFR 50.55a(f)(4)(i) and (ii) to relax time schedule for complying with latest edition of ASME OM Code for IST programs from 12 months to 18 months before applicable milestones.

38

Specific OM Items of Interest in Proposed Rulemaking

  • Amend 10 CFR 50.55a(b)(3)(ix) to specify that Subsection ISTF in 2017 Edition is acceptable without conditions. Also, when applying Subsection ISTF in 2015 Edition, Mandatory Appendix V requirements must be satisfied.

39

Specific OM Items of Interest in Proposed Rulemaking

  • Simplify (b)(3) conditions to refer to (a)(1)(iv) rather than specific ASME OM Code editions and addenda.
