val of an alternative method should include a supporting technical basis and acceptance criteria for its use. The reviewer should confirm that any previously approved alternative method credited in an application is approved for the use described in the D3 assessment. If an application credits an alternative method not previously approved by the NRC or not previously approved for the particular application in the D3 assessment, the reviewer should confirm that the application includes a sufficient technical basis for the NRC staff to determine its adequacy. The staff should review such applications on a case-by-case basis. Acceptance Criteria If an application uses NRC-approved alternative methods to eliminate a potential CCF from further consideration, the reviewer should conclude that the application provides sufficient information on the credited alternative methods if it includes the following: a. an identification of the source of vulnerabilities for which the NRC-approved alternative methods are being applied b. a description of the NRC-approved alternative methods being credited to address the identified vulnerabilities c. the supporting technical basis and acceptance criteria to demonstrate that these alternative methods are NRC-approved d. a description of how these alternative methods will address the CCF vulnerability and any potential spurious operations e. the technical basis explaining why these alternative methods are acceptable for addressing the identified CCF vulnerabilities and preventing or mitigating their effects, including an analysis of how the methods’ effectiveness can be demonstrated As stated above, if the application credits alternative methods not previously approved by the BTP 7-19-23 Revision 8 – January 2021 NRC, the reviewer should determine their adequacy on a case-by-case basis. 3.1.4 Use of a Qualitative Assessment and Failure Analysis to Eliminate the Potential for Common-Cause Failure from Further Consideration RIS 2002-22,
