for nuclear power plant components which are acceptable to the staff for implementation in the licensing of nuclear power plants. Code Cases pertaining to ASME Code Section III, Division 2, as well as Code Cases alternatives to Regulatory Guides 1.84, 1.147, or 1.192, or for those not covered in Regulatory Guides 1.84, 1.147, or 1.192 may be acceptable in either of the following cases: 5.2.1.2-4 Revision 3 - March 2007 1. If the proposed Code Cases provide an acceptable level of quality and safety; or 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. Technical Rationale The technical rationale for application of these acceptance criteria to the areas of review addressed by this SRP section is discussed in the following paragraphs: 1. Compliance with General Design Criterion 1 requires that SSCs be designed, fabricated, erected, and tested to quality standards commensurate with the importance of the safety functions to be performed.

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.

The staff endorses the application of Code Cases that
