Excellence method in maintenance with application for cryogenic nuclear unit (EMAC)

Full text: Cryogenic Nuclear Plant (CNP) has as main objectives the development of a technology for the removal of tritium from heavy water used in nuclear plants of CANDU type and finding of a methodology for complete inspection of the equipment used in the presence of tritium at very low temperatures. These aims imply achieving two main stages. The first stage concerns the maintenance conception on a scientific basis, while the second stage concerns the implementation. The first stage implies the management of maintenance in constraints relating to quality, risk and cost. The second stage regards the aspect of design and technology of CNP maintenance. The solution adequate with this conception will lead to a solution viable for implementation. The operative maintenance will be based on RCM (Reliability Centered Maintenance), using NOLAN and HEAP 1978 methodologies. The integrated maintenance through research and implementation demonstrates the design, realization of equipment, the dynamic and and the static complex uses of EMAC in CNP. It is a method of conception and implementation that integrates maintenance for the life cycle in the considered cryogenics systems. The implementation is achieved by means of the software LabVIEW applied to the specific objectives of the Program for Operative Maintenance in Temporal Dynamic Regime (POMTDR). (author)
