| 94-341 | Codes and Standards for Nuclear Power Plants; Subsection IWE and Subsection IWL | Proposed Rule | The Nuclear Regulatory Commission (NRC) proposes to amend its regulations to incorporate by reference the 1992 Edition with the 1992 Addenda of Subsection IWE, ``Requirements for Class MC and Metallic Liners of Class CC Components of Light-Water Cooled Power Plants,'' and Subsection IWL, ``Requirements for Class CC Concrete Components of Light-Water Cooled Power Plants,'' of Section XI, Division 1, of the American Society of Mechanical Engineers Boiler and Pressure Vessel Code (ASME Code) with specified modifications and a limitation. Subsection IWE of the ASME Code provides rules for inservice inspection, repair, and replacement of Class MC pressure retaining components and their integral attachments and of metallic shell and penetration liners of Class CC pressure retaining components and their integral attachments in light-water cooled power plants. Subsection IWL of the ASME Code provides rules for inservice inspection and repair of the reinforced concrete and the post-tensioning systems of Class CC components. Licensees would be required to incorporate Subsection IWE and Subsection IWL into their routine inservice inspection (ISI) program. Licensees would also be required to expedite implementation of the containment examinations and complete the expedited examination in accordance with Subsection IWE and Subsection IWL within 5 years of the effective date of this rule. Provisions have been proposed that would prevent unnecessary duplication of examinations between the expedited examination and the routine 120-month ISI examinations. Subsection IWE and Subsection IWL have not been previously incorporated by reference into the NRC regulations. This proposed amendment would specify requirements to assure that the critical areas of containments are routinely inspected to detect defects that could compromise a containment's pressure-retaining integrity. | 1994-01-07 | 1994 | 1 | https://www.federalregister.gov/documents/1994/01/07/94-341/codes-and-standards-for-nuclear-power-plants-subsection-iwe-and-subsection-iwl | Nuclear Regulatory Commission | 383 | The Nuclear Regulatory Commission (NRC) proposes to amend its regulations to incorporate by reference the 1992 Edition with the 1992 Addenda of Subsection IWE, ``Requirements for Class MC and Metallic Liners of Class CC Components of Light-Water Cooled... |
