CD/FSAR for acceptability for reference by COL applicants in preparing the safety evaluation report (SER) on the design certification application. The NRC then reviews the program description provided in the COL FSAR in preparing its SER on the COL application. Therefore, the full description of the environmental qualification program is provided by the combination of the design certification DCD/FSAR and the COL FSAR, together with the NRC SERs on the design certification application and the COL application. Reviews to determine compliance with related requirements for (1) dynamic and seismic qualification of electrical, I&C and mechanical equipment, (2) protection of electric and mechanical equipment against other natural phenomena and external events, (3) functional qualification of mechanical equipment, (4) equipment survivability for the length of time for which its function is required, and (5) qualification of I&C equipment located in mild environments are described in SRP Appendices 7.1-B, “Guidance for Evaluation of Conformance to IEEE Std. 279,” and 7.1-C, “Guidance for Evaluation of Conformance to IEEE Std. 603.” The specific areas of review are as follows: 1. Mechanical, electrical, and I&C equipment associated with systems described in this paragraph are reviewed to determine whether they are designed to meet the requirements described under the acceptance criteria of this SRP section. Mechanical, electrical, and I&C equipment covered by this SRP section include the following: A. Equipment associated with systems that are essential for shutting down the reactor and maintaining it in a safe shutdown condition, containment isolation, reactor core cooling, and containment and reactor heat removal, or otherwise are 3.11 -5 Draft Revision 4 – December 2017 essential in preventing significant release of radioactive material to the environment, B. Equipment that initiates the above functions automatically, C. Equipment that is used by the operators
