Specialised nuclear engineering

Specialised engineering for nuclear and industrial risk management

MILLENNIUM has always specialised in nuclear engineering and is nowwell-known for its expertise in the area of risk management.The service offer from MILLENNIUM covers a wide range of areas includingdesign, training services, modelling and scientific calculations, and providesa fully integrated response to the needs of nuclear operators running civilian or military facilities.MILLENNIUM has staff working close to all the major french nuclear sites,organised in project teams in which experts and design engineers work together to offer innovative, high-performance solutions that meet all therelevant quality, deadline and cost requirements.Our multidisciplinary approach is illustrated by the four MILLENNIUM key-words, which have been guiding our development from the very outset:⁍ Design ⁍ Calculation⁍ Demonstration ⁍ Training

> DesignMILLENNIUM offers its expertise in design projects for nuclearfacilities and components, using design tools developed by ourin-house design team and our expert R&D unit.

Design of nuclear HVAC systems:• Air-handling systems and balancing• Filter systems• Functional analysis of control systems (fire, contamination, etc.)

Layout of process equipment:• Gloveboxes• Filters• Shielded cells

Mechanical design:• Transportation and storage containers• Welded equipment• Lifting and handling systems

Design and Project Management for hazardous materials transportation packages:• Design and supervision of test model production• Qualification and testing on qualified test floor slabs• In-works production supervision, on-site acceptance

procedure

Decommissioning studies:• Definition of dismantling methods and tooling selection• Cost assessment and optimisation• Choice of decommissioning sequences• Design of nuclear measurement stations• Waste management and encapsulation

> Modelling and scientific calculations

MILLENNIUM’s teams of engineers and physics experts havedeveloped a comprehensive offer for nuclear and non-nuclearscientific calculations.Our specialists are experts in using all the design calculationtools available: computing codes designed by CEA, IRSN,EDF, international codes and our own in-house codes.These tools are used in technical platforms featuring powerful computing clusters.

Nuclear calculations:• Source terms• Health physics, ALARA studies, skyshine effect• Neutron activation• Simulation of nuclear measurements• Radiolysis• Dispersion/contamination/impact• Criticality/neutronics

Non-nuclear calculations:• Thermal calculations• Fluid mechanics• Nuclear HVAC/air-handling systems• Structural mechanics• Fire and smoke propagation simulations

Key references:• Definition of the ALARA approach on the New Safe

Confinement project, Chernobyl• Optimisation of radiation protection provision for

EDF engineering centres• Design of nuclear characterisation stations for

decommissioning operations at the CHOOZ A power plant• Fire studies and simulations in a building of CIS BIO

Key references:• Design safety for the STEMA project - CEA Marcoule• Safety analysis for the safety review of the GRIFFONOS system - CEA Saclay• Environmental history audit for EDF sites

> Safety analysis and inspections

MILLENNIUM’s teams of engineers specialising in nuclear safety studies, security, environment, crisis management and nuclear chemistry can provide assistance to clientsthroughout the facility life cycle.

Nuclear safety for facilities:• Safety analyses and compilation of safety analysis reports• Assistance and consultancy in design and operation• Expert assessment and audits of containment, criticality and radiation protection provisions

Nuclear safety for transportation of radioactive substances: • Compilation and updating of safety analysis reports• Criticality, health physics and radiolysis studies• Licence applications

Industrial safety:• Risk analysis: preliminary risk analysis, FMECA, HAZOP• Hazard studies and impact studies• Accident scenarios

Occupational safety:• Occupational risk analysis• Occupational health and safety analysis• Explosive atmosphere diagnostics and zoning

Environment:• Statutory site application files: water intake and release

permits, presentation of facility safety, site emergency plan• Environmental studies• Release scenario studies• Nuclear facility licensing applications

Crisis management:• Organisation of crisis cells• Assessment of proposals and scenarios• Participation in crisis drills

Nuclear chemistry:• Analytical chemistry (studies and on-site work)

• Radiochemistry • Chemistry of waste processing

Key references:• Radiological zoning design for the turbine hall of a BWR• Study into radiolysis phenomena for fuel blocked in a reactor

channel in China• Development of an activity estimation method based on dose

rate measurements, subsequently adopted by EDF

> Expert assessmentsMILLENNIUM’s experience in the nuclear field and active participation in major international conferences has enabled usput together a group of experts who can analyse any complexsituation at any phase of facility or component life.

• Task forces to analyse exceptional situations • Development and implementation of ALARA strategies• Consultancy for the largest clients in the field• Development of complex mathematical methods for implementation

in engineering tools• Design of decision-making aids• Nuclearisation and/or industrialisation of processes developed by research

centres (dispersion, HVAC, fire systems etc.)

> Specialised training servicesMILLENNIUM draws on its extensive expertise to offer awide range of standard or bespoke training programmesfor various audiences (managers, operators, etc.). The training services offered by MILLENNIUM are part of theoverall Nuvia training offer.

Examples of courses available: • Safety analysis• Regulations on the transportation of radioactive substances• Nuclear risk management (courses for operators and

management from operating companies)

• Criticality risks (calculations, analysis, accident phenomenology)• Radiolysis risks (phenomenology, analytic and computer

code calculations, risk analysis)• Radiation protection• Use of specific computer codes/software packages
