COOPERATION WITH THE EUROPEAN COMMISSION

Eletronuclear developed a two year project with the EC to upgrade Safety

Related I&C of Angra 2.

The project aimed to define a strategy for the replacement of the existing

analogue I&C equipment currently used in Angra 2, mainly the systems

important to safety.

The project reached its conclusion in the beginning of 2013.

The results has been used to modernize Angra 2 safety related I&C.


What we have done successfully regarding Monitoring?

Upgrade of Plant Process Computer – SICA

Installation of Thermal Transient Monitoring System

Upgrade of LPMS and Vibration Monitoring System

Upgrade of Aeroball System

Upgrade of Reactor Vessel Level Instrumentation System

What we are planning to do regarding Monitoring?

Modernization of Gas Stack Monitoring (KLK)

Modernization of Radiation System (replacement SINUPERM M)

Modernization of Physical Protection System - (CZ)


What we have done successfully regarding Control?

Modernization of Chlorination System

Modernization of Turbine Building Crane Control

Modernization of Polar Bridge Crane Control

Modernization of Boiler Control Loops

Modernization of Reactor Control System (JS)

What we are planning to do regarding Control?

Modernization of Refueling Machine


• HFE – Angra unit 1 - Simplified guidance to aid in definition of MCR/MCB

“End Point Vision”. I&C digital upgrade for process control systems. Angra

unit 3 HFE requirements FSAR chapter 18;

• New technologies applied to digital I&C systems (Ex: Neural Network,

Fuzzy Inference Systems and Big Data) ;

• Tech Meeting topics to exchange informations – Control loops tuning for

non expected transients (Ex: 100% load rejection), System Health

Management, V&V of digital I&C upgrades and VDU based MCR design;

• Cyber Security – Managing external and internal security of digital

systems. Managing domain policies.

• Ageing management of electrical equipment and components (IGALL).

4- Recommendations to IAEA programme (2018 to 2021)
