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.

Nuclear power plant: development of intelligent hydroelectric solutions

Vision

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

Mission

We create intelligent instrumentation and automation systems for a cleaner world in the areas of energy, industry and marine. Since 1959, we create services innovative as well as personalized tools: intelligent sensors, monitoring systems efficient and automation. All these products are intended to energy, industry and the marine industry.

Values

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

In addition to this, we educate our employees 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 deploy its own environmental and social project activities. All collaborators are involved in this challenge CSR.

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

CMR analyzes the life cycle of its products as well as the composition of raw materials to perfect waste recycling. The R & amp; D department centralizes 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 examines every year its carbon footprint in order to decrease it. Actions to improve the transport of raw materials and finished products are at the heart of its concerns.

Solar

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

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

The conversion of thermal power plants into hybrid plants gives many benefits to the customers of these facilities:

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

Our HYLIOS solution is particularly reserved for emerging countries largely 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 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:

  • » maximize electrical efficiency
  • »Decrease the use of fuels
  • ' increase self-consumption
