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.

Electricity for nuclear power plant: creation of intelligent hydroelectric solutions

Vision

Energy, industrial and marine players are studying actively renewable, low carbon sources of energy. Our will is to enable access to these renewable energies. How? 'Or' What ? By shaping hybrid and microgrid solutions, which improve energy and storage efficiency.

Mission

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

Values

Our values ​​ are those that drive our operations and advance our business. United, all collaborators who form our teams consolidate our virtues and work ardently to promote them.

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

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

CMR examines every year its carbon footprint in order to reduce it. Actions to optimize the transport of raw materials and finished products are at the heart of its concerns.

CMR auscultates the life cycle of its products as well as the constitution of raw materials to optimize waste recycling. The R & amp; D department concentrates its efforts on the integration of sustainable development at all levels of the company .

Use case

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

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

Solar

We design 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 gives many benefits to the customers of these facilities:

  • » major reduction in consumption of fuels
  • »Strong decrease in CO2 emissions
  • »Gain in competitiveness on the price of the electricity produced
  • » decrease in maintenance tariffs.

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

The complexity 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 available for autonomous and nomadic mini-power plants but also for large hybrid ground installations.

Our energy management system offers many features for:

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