of nuclear power plants. c. Regulatory Guide 1.147, "Inservice Inspection Code Case Acceptability, ASME Section XI, Division 1." This guide lists those Section XI ASME Code Cases which are acceptable to the staff for use in the inservice inspection of components and their supports, as described in the first paragraph of subsection I, in light-water-cooled 21 nuclear power plants. Code Cases pertaining to ASME Code Section III, Division 2, as well as Code Cases alternative to II.2.a, II.2.b, or II.2.c or those not covered in II.2.a, II.2.b, or II.2.c may be acceptable in either of the following cases: (1) If the proposed Code Cases provide an acceptable level of quality and safety; or 5.2.1.2-3 DRAFT Rev. 3 - April 1996 (2) If compliance with the specified requirements of 10 CFR 50.55a would result in hardship or unusual difficulty without a compensating increase in the level of quality and safety.22 Technical Rationale The technical rationale for application of acceptance criteria for compliance with General Design Criterion 1 and 10 CFR 50.55a is discussed in the following paragraphs:23 A.

Code Cases for Section III, Division 2, and other Code Cases that may be proposed are reviewed on a case-by-case basis. Under these Code Cases, components of the reactor coolant pressure boundary and other specified components must meet specific criteria that have been reviewed and accepted by the staff. 24 The ASME Boiler and Pressure Vessel Committee adopts Code Cases that provide additions, revisions and
