Mesit and CCRI research and technological development and advanced engineering services, typically operates in cooperation agreement with leader companies, with the aim at tackling national and international markets also with the development of innovative products. Mesit and his engineering partner CCRI perform traditional and advanced engineering specialties and detailed design for various projects for their worldwide Clients including traditional disciplines, architectural, civil, electrical, mechanical, piping, and structural engineering including simulation, integrated automation processes, and interactive 3D and 4D modeling.

 

CCRI main field of activities are:

Nuclear Power Plants as decommissioning, power plant design and innovative development;

Process, Steel working, Power Plants, Chemical process plants and Renewable energy plants;

Advanced Mechanical componets and system as remote handling, automotive, aerospace, etc.

 

The CCRI stable manpower includes 110 highly skilled technicians, mainly PhDs and engineers.The basic engineering production capacity, based on the permanent personnel, is around 150.000 h/y. The turnover of the Companies of the Consortium is 15 MEU/y. In addition to the internal resources, CCRI has the availability of external staff, with specific competence in different fields, thanks to a proven network of cooperation with specialized companies, supported by specific cooperation agreement. CCRI technical structure is set in five technical areas: civil, mechanical, elecrtical, automation and nuclear. 

 

R&D activities are carried out both at technical area level and at a level crosscutting different technical areas, as well as under the coordination of dedicated professionals.

In the following, for each technical areas it is reported a description of the technical capabilities of the company, the internal staff, the standards and rules applied and the computer programs utilized.
