TY - JOUR A1 - Álvarez Torres, María Bárbara AU - Iborra García, Andrés José AU - Fernández Andrés, José Carlos T1 - An automatic maintenance system for nuclear power plants instrumentation Y1 - 2000 SN - 1375-6753 UR - http://hdl.handle.net/10317/590 AB - Maintenance and testing of reactor protection systems is an important cause of unplanned reactor trips due to be commonly carried out in manual mode. The execution of surveillance procedures in this mode entails a great number of manual operations. Automated testing is the answer because it minimises test times and reduces the risk of human errors. GAMA-I is an automatic system for testing the reactor protection instrumentation which is based on VXI instrumentation cards. This system has important advantages over previous ones in terms of easiness to carry out software modifications related to configuration changes in the protection system. The system uses visual programming and the modifications can be implemented by ordinary instrumentation specialists without programming experience.
