Nuclear Application Maps (4 of 14) – Regulatory Management

Operating organizations must comply with requirements that are based on external and internal regulations. The records of the Tech Spec application represent the technical specifications or equivalent regulations that apply to your organization. The technical specifications are approved by the relevant regulatory authority and an operating organization must demonstrate compliance in order to be able to retain the operating license. The records entered in the Surveillance Requirement application and associated with the tech spec help to prove that the requirements are being satisfied. Tech Spec records and Surveillance Requirement records are under revision control.   

Tech Specs are related to a site and unit and one or more modes of plant operation and/or a Mode Entry Requirement (MER). Tech Specs are also associated with plant components, locations and by association the assets of those locations. There may be conditions which limit the capability of the components and the actions to follow when this condition occurs, these are referred to as Limiting Conditions for Operations (LCO). The actions that are required have time limits and may need to be repeated at a frequency. The actions may also be based on a combination of conditions. This is all documented and approved as part of the regulations for the plant. What Maximo provides is the ability to model this data and use it in other Maximo applications particular Preventive MaintenanceImpact Plans and Work Order Tracking.

Limiting Conditions for Operations (LCOs) may be planned as part of maintenance or are unplanned when there are equipment issues. The LCO Tracking application allows you to track these planned and unplanned events, link the appropriate tech specs, monitor the defined actions and manage the processing of these actions. LCOs are linked to various Maximo records as well as the work orders or corrective actions that brought about the creation of the LCO. They are also linked to the surveillance work orders that are part of the retesting of the components following maintenance or correction of the component fault.

Surveillance testing is set-up in Maximo by referencing Surveillance Requirements on a Preventive Maintenance record and generating work orders either on a frequency basis or on demand. In Work Order Tracking you can add completion codes that indicate the success or failure of the surveillance tests.
