Ageing Management of Specific Instrumentation
and Control Systems of the LVNPP
- several systems of the plant have been identified as possible
fields of action for upgrading or reinforcement.
- we focus in common problems encountered in I&C systems
i.e. in the Starting Range Neutron Monitoring System, SRNMS
Instituto Nacional de Investigaciones Nucleares, México
-
Measurement of the neutron fluxes
-Review of the instrumentation used in the Starting
Range Neutron Monitoring System, SRNMS
-Recomendations for the verification and inspection
of the SRNMS in LVNPP
-Grounding,shielding and protection of electronic
equipments to reduce the electromagnetic
interference and transients in nuclear
instrumentation

RECOMMENDATIONS
• Consider a training course on Wireless Technologies
applications on NPPs in 2016.
• Add a worshop on aging management of I&C components in
2016.
• Look for more benefits for MS in:
- Application of codes and standardsCC., 2016
- Application of diversity, independence and physical
separation in different levels of I&C systems, 2017
• Add a training course on the process performance
optimization, including new radiation detectors technologies,
and stressing the importance of full understanding of the
processes, 2017.
• Add a training course on maintenance of digital I&Csystems in
2016.
• Add a training course on dedication of I&C systems and
components in 2016.
• Consider a consultant meeting that includes also sellers of
new I&C components for NPPs in 2016.
• Discuss the importance of right selection of participants in the
propossed events (WS, TC mainly)
Instituto Nacional de Investigaciones Nucleares, México
• To promote the disemination of information
about:
- Operational experiences and solutions on
common problems encountered in I&C
systems of NPPs
- Recommendations and Guidelines for
best practices
