Content:
nventory list for the main control room and the controls, displays and alarms required on systems to remotely shutdown the reactor should be included in Tier 1. The items required for operation of the remote shutdown system may be designated on the figures for the individual systems, or listed in the remote shutdown system in Tier 1. Detailed supporting information is contained in Chapter 7 of Tier 2. The individual systems that contained the sensors for the displays, controls, and alarms should be reviewed to ensure that standard ITAAC entries were used to verify their function. The design processes and acceptance criteria specified in Tier 1 for I&C equipment, particularly the verification and validation aspects of the I&C design, will verify proper operation of the I&C aspects of the equipment. Similarly, the design processes and acceptance criteria for HFE contained in Tier 1, particularly the verification and validation aspects of the HFE design, will verify proper design and operation of the equipment for human factors aspects. The ability of these controls, displays and alarms to function should be checked during operation of the system for the functional tests required by the system ITAAC. Because the intent of the ITAAC is to verify the final as-built condition of the plant, the operation of the system during the completion of the functional tests required in the system ITAAC should be conducted from the MCR. Therefore, the verification that the system can be operated from the MCR need not be a separate ITAAC. Also, because the operation of the equipment from the control room demonstrates the control function, continuity checks between the RSS and the equipment demonstrates that the control signal will be received by the component and provides adequate assurance that the equipment can be operated by the RSS. The results of the pre-operational test program may be utilized to demonstrate the ability to operate plant equipment by the RSS. III. REVIEW
