Principle and operation

The fission of uranium atoms produces heat, which then transforms water into steam and sets in motion a turbine connected to an alternator which produces electricity.

1. The primary circuit
In the reactor, the fission of uranium atoms produces a large amount of heat. This heat increases the temperature of the water circulating around the reactor, to 320 ° C. The water is kept under pressure to keep it from boiling. This closed circuit is called the primary circuit.

2. The secondary circuit
The primary circuit communicates with a second closed circuit, called the secondary circuit, via a steam generator. In this steam generator, the hot water of the primary circuit heats the water of the secondary circuit which turns into steam. The pressure of this vapor turns a turbine which in turn drives an alternator. Thanks to the energy supplied by the turbine, the alternator produces an alternating electric current.

A transformer raises the voltage of the electric current produced by the alternator so that it can be more easily carried in very high voltage lines.

3. The cooling circuit
At the outlet of the turbine, the steam from the secondary circuit is again transformed into water thanks to a condenser in which circulates cold water from the sea or from a river. This third circuit is called the cooling circuit. On the banks of the river, the water in this 3rd circuit can then be cooled by contact with the air circulating in large towers, called air coolers.

The 3 water circuits are watertight with respect to each other.

Reactor automation: development of intelligent hydroelectric solutions


Energy, industrial and marine companies are researching actively renewable, low carbon sources of energy. Our wish is to promote access to these renewable energies. How? 'Or' What ? By deploying hybrid and microgrid solutions, which maximize energy and storage efficiency.


We compose intelligent instrumentation and automation systems for a cleaner world in the sectors of energy, industry and marine. Since 1959, we assemble services innovative and also tailor-made tools: intelligent sensors, monitoring systems advanced and automation. All these products are dedicated to energy, industry and the marine industry.


Our virtues are those that guide our operations and improve our business. United, all employees who constitute our teams defend our values ​​ and work ardently to promote them.

In addition to this, we educate our employees about the consumption of energy resources and limit consumption of & # 039; water, energy or even paper (recycling, communications, ...).

Energy and education are the guidelines of CSR policy. CMR is committed to deploy its own environmental and social project activities. All employees are committed in this challenge CSR.

CMR analyzes every year its carbon footprint for reduce it. Actions to perfect the transport of raw materials and finished products are at the heart of its concerns.

CMR compares the life cycle of its products as well as the constitution of raw materials to improve waste recycling. The R & amp; D department centralizes its efforts on the integration of sustainable development at all levels of society.

Use case

Energy and education are the guidelines of CSR policy. CMR is committed to deploy its own environmental and social project activities. All collaborators are committed in this challenge CSR.

CMR analyzes every year its carbon footprint for reduce it. Actions to perfect the transport of raw materials and finished products are at the center of its concerns.


We produce and deliver turnkey solar or hybrid power plants for micro-grid, industrial or grid-connected installations.

La solution HYDROS designed by CMR makes it possible to hybridize diesel generator installations with solar production and potentially storage.

The transformation of thermal power plants into hybrid plants delivers many benefits to the customers of these facilities:

  • »Significant reduction in consumption of fuels
  • »Strong decrease in CO2 emissions
  • »Gain in competitiveness on the tariff of the electricity produced
  • » decrease in maintenance costs .

Our HYLIOS solution is essentially reserved for emerging countries strongly dependent on thermal production, but releasing significant solar potential.

The difficulty of hybrid thermal power plants consists in the dimensioning of the equipment of the thermal part, the storage, and in the piloting. The goal is to to ensure a continuous supply of electricity to customers.

Our HYLIOS solution is equipped with an energy flow management and control system, making it possible to meet the consumption of energy needs. This solution is usable for autonomous and nomadic mini-power plants but also for large hybrid ground installations.

Our energy management system offers many features for:

  • » increase electrical efficiency
  • » reduce the use of fuels
  • 'Improve self-consumption
