he nuclear power plant. The V&V activities and tasks should include system testing of the final integrated hardware, software, firm-ware, and interfaces. The software V&V effort should be performed in accordance with IEEE Std 1012-1998 which is endorsed by NRC Regulatory Guide 1.168, Revision 1. The IEEE Std 1012-1998 V&V criteria for the highest integrity level (level 4) apply to systems developed using IEEE Std 7-4.3.2-2003. 5.3.4 Independent V&V (IV&V) Requirements (IEEE Std 7-4.3.2-2003 Sub-Clause 5.3.4) The previous subsection addresses the V&V activities to be performed. This subsection defines the levels of independence required for the V&V effort. IV&V activities are defined by three parameters: technical independence, managerial independence, and financial independence. The development activities and tests should be verified and validated by individuals or groups with appropriate technical competence, other than those who developed the original design. Oversight of the IV&V effort should be vested in an organization separate from the development and program management organizations. The V&V effort should independently select: • The segments of the software and system to be analyzed and tested, • The V&V techniques, and • The technical issues and problems upon which to act. Appendix 7.1-D-11 March 2007 The V&V activities and tasks should include system testing of the final integrated hardware, software, firm-ware, and interfaces. The V&V effort should be allocated resources that are independent of the development resources. The reviewer of the V&V effort should evaluate the overall effectiveness of the V&V process. Since the NRC staff can not perform a review of every requirement and every line of code, the staff relies on the V&V completeness and rigor of the V&V effort to provide reasonable assurance of high quality software development. With this in mind, the items the reviewer should check include, but are not limited to the following: i. Is the
