The AMI (Atelier des Matériaux Irradiés), INB n°94 located on the CNPE of Chinon, is a laboratory used to assess the behavior of active materials from the UNGG and PWR power plants, and to carry out the treatment of historical waste.
The service consists of carrying out studies and dismantling work on all or part of the equipment present in 255 premises of the main building of the AMI located in controlled areas, in supervised areas and in public areas.
The service is part of the AMI's overall dismantling project, and is the last dismantling work before the renovation phase of the building.
The Holder will be responsible for its dismantling scenario, the kinematics of the waste, and the preparatory work to be carried out to achieve the expected results, provided that the various constraints developed in the specifications are respected.
The service is part of the AMI's overall dismantling project, and is the last dismantling work before the renovation phase of the building.
This laboratory, commissioned in 1963, is composed of 450 premises (including about 250 in controlled areas). These premises are spread over 6 levels.
The service concerns:
- the electromechanical dismantling of 255 AMI premises, including 246 located in controlled areas,
- the demolition of the CC201 to CC207 High Activity cells and the wells of room CS272.
The physical inventory includes, as an indication: 845 tonnes of waste relating to electromechanical dismantling, and 3,000 tonnes of waste relating to the demolition of civil engineering.
Some premises are concerned by potential work at alpha risk.
Asbestos, lead and FCR material identification reports indicate the presence of asbestos and lead at some locations in the MAI.
Some of the service's work is likely to emit dust containing Cellular Crystalline Silica (SCA).
The service includes:
- design studies,
- implementation studies,
- factory manufacturing and qualifications, supplies,
- on-site work (including installation and site withdrawal),
- participation in journals,
- visits to control the environment of the premises and to carry out the necessary temperature surveys.
The incumbent will be responsible for all human and material resources necessary for the service. He will ensure the overall coordination and management of the service (planning, interfaces, gaps, etc.).
The Holder shall have full discretion in the choice of design and in the definition of the means to be used, provided that it complies with the requirements and specifications expected as specified in the documents of the Contract.
The Account Holder will have an obligation of result.
The issues related to the delivery are outlined below. The list of issues may evolve depending on the scenario proposed by the Holder.
Issues are at the heart of the Company's oversight of the Holder's performance.
- Control of the schedule to guarantee a duration of the work of 4 years;
- Control of radiation protection, with the presence of red and orange zones, and alpha contamination;
- Waste management by controlling the production of dismantling waste packages as well as induced and technological waste, i.e. by optimising their packaging in terms of quality and quantity and in compliance with ANDRA and CENTRACO specifications;
- Ensure the structural strength of the building, especially during the demolition phases of the HA cells and shafts of room CS272;
- Safety by enforcing safety rules during the construction site installation, work and site withdrawal phases. Particular attention is paid to the control of vehicular / pedestrian / waste flows, work at height, handling and operations in the presence of hazardous materials and substances (asbestos, lead, silica, etc.);
- The control of the radiological cleanliness of the installations by the application of procedures for maintaining cleanliness during the work phases.
