e should have the intended configuration recorded in the ICT, and the reviewer should sample these configuration items to verify that they are correct. The reviewer should verify that the V&V team has already made this determination, and should then sample various items. For example, the reviewer could verify that setpoints shown in the ICT agree with values determined by setpoint calculations. Other configuration items may require reference back to the original system specification. The ICT is a critical item for configuration management, both by the vendor and by the applicant/licensee. B.3.3.7 Installation Activities - Operations Manuals (OMs) NUREG/CR-6101, Section 3.7.1 “Operations Manual,” contains relevant guidance. One or more software OMs should be produced. They may be incorporated into a system operations manual. Because operations manuals do not impose requirements on the software itself, the functional characteristics described in other sections of this BTP are not directly relevant. However, the software development process characteristics listed below should be exhibited by software operations manuals. B.3.3.7.1 Process Characteristics of OMs The OMs exhibit each of the specified software development process characteristics: completeness, consistency, style, traceability, and unambiguity. Completeness means that all actions available to the system operator are fully described for all operating modes, including error recovery and backup. Operator actions should be specified in terms of inputs supplied by the operator or equipment, actions initiated by the operation, and responses to the operator. The purpose and operation of each function should be described, including interfaces with other functions. The operations manual should describe the operational environment within which the software will operate, including precautions and BTP 7.14-64 Revision 5 - March 2007 limitations that must be observed during operations to avoid exposing personnel or
