n responsibilities of plant personnel, the procedures and resources necessary for the repair of systems required to achieve and maintain cold shutdown, nor does it usually result in an increase in the potential for a radiological release resulting from a fire. The licensee=s submittal should confirm that the power uprate results in no changes to these elements, and this finding should be reflected in the staff=s safety evaluation. If the licensee indicates that there is an impact on these elements, the staff should review the impact against the acceptance criteria in the applicable sections of this SRP to ensure that the Commission=s fire protection goals are satisfied. The systems relied upon to achieve and maintain safe shutdown following a fire may be affected by the power uprate due to the increase in decay heat generation following a plant trip. For fire events where the licensee is relying on one full train of the redundant systems normally used for safe shutdown, the licensee=s analysis of the impact of the power uprate on the important plant process parameters performed for other plant transients, such as a loss of off-site power or a loss of main feedwater, will typically bound the impact for a fire event such that a specific analysis for fire events is not necessary. However, where a licensee relies on less than full capability systems for fire events, such as partial automatic depressurization or a reduced capability makeup pump, the licensee should provide a specific analysis for fire events that demonstrates that the fuel design limits are not exceeded, that fuel integrity is maintained and that there are no adverse consequences on the reactor pressure vessel integrity or the attached piping. Licensees that rely on alternative/dedicated or backup shutdown capability for post-fire safe shutdown should analyze the impact of the power uprate on the alternative/dedicated or backup shutdown capability. The staff should verify that the alternative/dedicated
