re generally achieved and demonstrated by proper incorporation of all relevant environmental conditions into the design process, including the equipment specification. In addition, Regulatory Guidance for Environmental Qualification of Safety-Related Computer-based Instrumentation and Control Systems is provided in Regulatory Guide 1.209, “Guidelines for Environmental Qualification of Safety-Related Computer-Based Instrumentation and Control Systems in Nuclear Power Plants.” RG 1.209 addresses I&C equipment in mild environment simply because of the normal location of such equipment. In SRM-SECY-02-0067, “Inspections, Tests, Analyses, and Acceptance Criteria for Operational Programs (Programmatic ITAAC),” the NRC staff recommended that combined license (COL) applications for nuclear power plants submitted in accordance with the requirements of 10 CFR Part 52, “Licenses, Certifications, and Approvals for Nuclear Power Plants,” contain ITAAC for operational programs required by regulations to the extent that such ITAAC are necessary and sufficient to support the finding that the facility has been constructed and will be operated in conformity with the license, the provisions of the Atomic Energy Act, and the Commission’s rules and regulations. In a Staff Requirements Memorandum (SRM) dated September 11, 2002, the Commission determined that a COL applicant is not required to have ITAAC for operational programs for a nuclear power plant licensed under 10 CFR Part 52 (with the exception of emergency planning). The Commission stated that “ITAAC for operational programs should not be necessary if the programs and their implementation are fully described in a COL application and found to be acceptable by the NRC staff at the COL stage.” The Commission noted that “the burden [was] on the applicant to provide the necessary and sufficient programmatic information for approval of the COL without ITAAC.” In SRM-SECY-04-0032, “Programmatic Information
