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

Page 14: Nuclear Power Plant Instrumentation and Control in · PDF fileInstituto Nacional de Investigaciones Nucleares, México Nuclear Power Plant Instrumentation and Control in MEXICO 25

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)

Page 25: Nuclear Power Plant Instrumentation and Control in · PDF fileInstituto Nacional de Investigaciones Nucleares, México Nuclear Power Plant Instrumentation and Control in MEXICO 25

• 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
