tems important to safety are discussed in Section 7.6 of the SAR. Control Systems are those systems used for normal operation that are not relied upon to perform safety functions following anticipated operational occurrences of accidents, but which control plant processes having a significant impact on plant safety. Control systems are discussed in Section 7.7 of the SAR. Essential Auxiliary Supporting Systems are those systems that must function to assure the capability of the instrument and control systems important to safety to perform safety functions. Heating, ventilation and air conditioning systems, electrical power systems, and cooling water systems are typical examples of essential auxiliary supporting systems. Essential auxiliary supporting systems are discussed in other chapters of the SAR. The instrumentation and control aspects of essential auxiliary supporting systems are addressed in the review of those SAR sections which discuss those systems. To the extent that the operation of essential auxiliary supporting systems are initiated by the protection system, this aspect is included in the review of the protection systems in Section 7.2 or 7.3 of the SAR. All other instrumentation and control systems important to safety such as fire protection, fuel handling, radiation monitoring, and control of essential auxiliary supporting systems are addressed in the review of other SRP sections which discuss these systems. The review of Section 7.1 of the SAR includes the tabulation of instrumentation and control systems important to safety and the acceptance criteria and guidelines applicable to each of these systems. The review also includes the identification of those instrumentation and control systems important to safety that are identi- cal to those which have previously been reviewed by the staff and where the adequacy of these systems is based upon prior Commission approval. The bases for prior approval includes the staff's evaluation of applications for
