tion of the resulting computer system with the nuclear power plant. The V&V activities and tasks should include system testing of the final integrated hardware, software, firmware, and interfaces. The software V&V effort should be performed in accordance with IEEE Std 1012 which is endorsed by NRC RG 1.168. The IEEE Std 1012 V&V criteria for the highest integrity level (level 4) apply to systems developed using IEEE Std 7-4.3.2. 5.3.4 Independent V&V (IV&V) Requirements (IEEE Std 7-4.3.2, 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. Appendix 7.1-D-11 Draft Revision 2 – August 2015 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 that is separate from the development and program management organizations. The V&V effort should independently select the following: • 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 The V&V activities and tasks should include system testing of the final integrated hardware, software, firmware, 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 cannot perform a review of every requirement and every line of code, the staff relies on the 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
