. 2. GDC 28 requires reactivity control systems designed with appropriate limits on potential reactivity increases so the effects of a rod ejection accident can result in neither damage to the reactor coolant pressure boundary nor result in sufficient disturbance to impair the core cooling capability. GDC 28 requirements apply to this section because the reviewer evaluates the maximum reactor pressure during any portion of the transient corresponding to a rod ejection. ASME Codes provide guidance for the acceptability of anticipated accident pressure. The review also examines the extent of fuel damage from a rod ejection accident. Regulatory Guide 1.77 and SRP Section 4.2 provide guidance for acceptability of anticipated core damage. This criterion provides assurance that the capability to bring the reactor to a safe shutdown condition will not be impaired by a control rod ejection accident. 15.4.8-4 Revision 3 - March 2007 3. 10 CFR 100.11 or 10 CFR 50.67 requires that the exclusion area and the low population zone be defined by assurances that specified limits for postulated fission product releases will not be exceeded in radiation doses to individuals at the outer boundaries of those regions. These requirements apply to this section because rod ejections are included among the potential accidents for which fission product releases are postulated. Review under SRP section 15.0.3 determines the source term used by the reviewer. These requirements provide assurance that offsite radiation doses from pressurized water reactor rod ejection accident will not exceed guideline doses specified in 10 CFR 100.11 or 10 CFR 50.67. III. REVIEW PROCEDURES The reviewer will select material from the procedures described below, as may be appropriate for a particular case. These review procedures are based on the identified SRP acceptance criteria. For deviations from these acceptance criteria, the staff should review the applicant’s evaluation of how the proposed alternatives
