Decommissioning ConsiderationDecommissioning plan should be reflected in all the steps9

Safety GoalCore Damage Frequency (CDF)Containment Failure FrequencyRadioactive material release targetThermal MarginFuel thermal marginOperator Grace TimeTo cool the RCS below the safe shutdown condition within 36hrTo keep the core undamaged for 72hr without any corrective actionsby operators11

Station Blackout MitigationTo be maintained at safe shutdown condition for at least 72 hoursunder the complete loss of onsite and offsite AC powerReactor shutdownTo be equipped the redundant and diverse means to perform a reactorshutdownHazards protectionTo be protected from internal events and external events12

Severe AccidentThe equipment to mitigate the effect of severe accident should beinstalled.
The equipment to prevent the hydrogen explosion and the directcontainment heating phenomenon should be installed.
The accident management program should be prepared to cope withthe severe accident.

ContainmentTo be designed to protect the reactor from external missile, seismic,tsunami, etc. and have the radiological shielding function whenaccidents occur13

Control Room HabitabilityAdequate radiation protection should be provided to permit accessand occupancy of the control room under accident conditions.

Ultimate Heat SinkThe capacity of the ultimate heat sink should be sufficient to providecooling for the time necessary to evaluate the situation and takecorrective action.
Site wet-bulb temperature and related meteorological information willbe supplied after an environment survey.

AvailabilityTo be designed considering the annual average availabilityTo be designed considering the number of unplanned reactor tripsLoad FollowReactor should have the capability of the daily load follow operation.
Sudden power change should be possible during power operation.

Load Rejection CapabilityOperation mode changes to on-site load should be possible withoutreactor shutdown at full power operation.
15MaintenanceThe maintenance conditions should be considered for the design ofstructures, systems and components.
Accessibility, maintenance space, install of lift rig, test and inspectionshould be considered for the maintenance.
The standardization of components and parts should be pursued forthe maintenance.
The maintenance facilities must be designed to facilitate the use of theautomatic equipment such as robots for the maintenance.

16

Aircraft CrashTo be designed to minimize the effects on the key safety function (corecooling, containment integrity, spent fuel storage integrity) of a large,commercial aircraft and military aviation.

Cyber SecurityTo be designed to protect the cyber threats for digitalized plantsystemsSabotageSecurity organization and physical protection program will beestablished and .
