Environmental protection
Calian has significant expertise in modelling and assessing the radiological impact of nuclear facilities and activities on the environment. We have performed several full-scope environmental impact assessments for new and existing nuclear facilities, changes in plant configuration, waste management programs and licensing renewals.
Radiation protection
Calian provides support to the nuclear industry, government and defence organizations for the development, implementation and certification of radiation protection and dosimetry programs. Our team has extensive experience in designing radiation shielding and evaluating its effectiveness for all forms of ionizing radiation (i.e., alpha, beta, gamma and neutrons).
Decommissioning and waste management
We have expertise in planning, performing, and evaluating the results of final status and characterization surveys in accordance with industry best practices (MARSSIM, MARSAME, CSA, EPRI) including development of conceptual, preliminary, and detailed decommissioning plans, historical site assessments and walk-downs to support scoping, waste stream definition, and health and safety planning, and support for decommissioning activities.
Regulatory affairs and licensing
Calian has extensive knowledge of nuclear regulatory requirements and standards, as well as comprehensive experience in supporting regulatory activities both in Canada and internationally, including the interpretation of regulatory requirements, development of a licensing strategy and providing support throughout its execution, as well as documenting a licensing basis in a safety case or a safety report.
Emergency preparedness and training
Calian is a leader in the provision of nuclear emergency management programs, training and exercises. We offer a full lifecycle approach to the conduct of drills and exercises, on both national and international platforms, by supporting the design, development, facilitation and evaluation of these exercises. Our team also has extensive expertise in the development of nuclear emergency management programs in compliance with regulatory, provincial, and federal requirements.
Nuclear safety analysis
Our team can support your facility’s nuclear safety and licensing activities. We provide comprehensive services including: HAZID, FMEA, on-site and off-site dose consequences, shielding evaluations, criticality evaluations, licensing requirements, regulatory compliance, and internal process compliance. Our team brings experts in safety analysis codes including: SCALE/ORIGEN, MCNP, MicroShield, ADDAM-IST and MACCS.
Systems engineering and robotics
We provide a full range of systems engineering capabilities including complete system design, development and deployment of automated inspection and maintenance equipment, sensor development and integration, control system upgrades, post-delivery operations support, as well as specialized engineering support and consultancy for safety, reliability, design methodology and failure assessment.
Our team applies this knowledge in research and development projects to create innovative robotics solutions to support outage reductions, improved maintenance, and radiation protection applications.
Project management and project controls
We have a strong track record as prime contractor for nuclear projects, with extensive experience and resources to provide oversight, project management, and project controls services. This includes: developing, baselining and maintaining project schedules in Primavera, preparation of project dashboards to communicate key performance indicators, resource loading and levelling, critical path analysis, risk identification through subject matter expert workshops, development of robust risk mitigation plans and maintenance of project risk registers, cost management and control, and development, implementation, and training of project management governance.
Quality culture
Quality is a core value at Calian and manifests itself across the organization. Calian maintains a quality management system that is certified to the ISO 9001:2015 standard and is compliant with CSA N299.1-16, CSA N286-12 and CSA N286.7-16 standards. Every year we undergo several internal and external audits to ensure that the implementation and effectiveness of the quality system is maintained and up to date with industry requirements.
