Content:
ating the ability to reliably control the amount and rate of reactivity change to assure that no reactivity accident will damage the reactor coolant pressure boundary or disturb the core or the core's appurtenances such as to impair coolant flow. The postulated reactivity accidents include rod ejection, rod drop, steam line rupture, coolant temperature changes, pressure changes, and cold water addition. 6. The applicant has met the requirements of General Design Criterion 29 by demonstrating a high probability of control rod insertion under anticipated operational occurrences. V. IMPLEMENTATION The following is intended to provide guidance to the applicants and licensees regarding the NRC staff's plans for using this SRP section. Except in those cases in which the applicant proposes an acceptable alternative method for complying with the specified portions of the Commission's regulations, the method described herein will be used by the staff in its evaluation of conformance with the Commission's regulations.
