Configuration Management (CM) guarantees that plant activities can be performed safely and appropriately, by maintaining the balance of the three elements (design requirements, facility configuration information, and physical configuration) that are the basis for securing the safety of the plant. If this becomes unbalanced, the risk of occurrence of events affecting nuclear safety will increase. Kansai Electric Power is developing a Design Basis Document (DBD) that summarizes design requirements in order to...

Configuration Management and Design Basis Document

When developing a maintenance program to be able to provide optimal maintenance activities for a whole plant system, positive adhesion to a maintenance system in compliance with each piece of equipment, facility and degradation mode is not sufficient; it is necessary to reflect considerations about the importance of facilities and matching between failure mode and maintenance system, arrangement for renewal of system components, as well as various requirements for the plant including the design basis. Thi...

In Japan, CBM (Condition Based Maintenance) has not been adequately introduced yet due to the lack of field data. To reduce possibilities of equipment failure because of improper work practice we have to optimize the condition monitoring technique. Mihama units 1 and 2 were decided to be decommissioned, so that a lot of equipment can be used to collect many kinds of condition monitoring data such as vibration, lubrication and thermography diagnosis including trends of degradation conditions without concerns...
