Engineering solutions that focus on quality and cost Plant modification

Architect engineer service

Rolls-Royce provides Architect Engineer (AE) Service to nuclear power stations and is currently a Prime AE for several nuclear stations.  As an Engineer of Choice at these power stations, Rolls-Royce is able to provide a wide array of engineering services for projects of all sizes.

Rolls-Royce maintains a NUPIC approved 10CFR50 Appendix B Quality Assurance Program for engineering services and software development.

Rolls-Royce supports both fixed price and time & material engineering projects for all engineering disciplines in the nuclear industry.  Roll-Royce also provides short-term staff augmentation.

Plant modification

At Rolls-Royce, we pride ourselves on helping nuclear utilities optimise plant lifetime through a variety of engineering solutions specifically designed with a focus on quality and cost-effectiveness, spanning obsolescence management, equipment reliability, custom reporting software and electronic modifications.

Our engineering services include both the supply of engineers who are located at nuclear power plants and managed by utility personnel and Rolls-Royce-led projects in areas such as plant design modifications, procurement support, regulatory support and procedure development.

We specialise in:

  • Design modification
  • Calculation analysis
  • Procurement services
  • Inventory reduction/analysis
  • Design/procurement specifications
  • Procedure upgrades

Staff augmentation

Rolls-Royce is able to provide on-site support at nuclear power stations across the world.  Depending upon the power station’s needs, Rolls-Royce will work with the customer and place appropriate personnel on-site for a suitable amount of time.  This support can provide utilities with flexibility of their engineering support.

Rolls-Royce personnel are able to provide power stations with design, procurement, and system engineering support, drafting services, work force support, document control and verification, planning, scheduling, project management, information and document management, technical support, process guidance, and procedural development for the nuclear industry.

Computer replacement services

Rolls-Royce has extensive experience in the replacement of plant monitoring systems, security computer systems, separation of emergency response data systems from existing plant systems, and the ability to perform online replacements, minimising plant downtime.

Benefits of Rolls-Royce computer replacement services:

  • extensive multi-discipline engineering experience within nuclear industry helps customers to minimise plant dontime
  • extensive engineering expertise in electrical, instrumentation and control, mechanical and structural plant modifications
  • advanced understanding of plant requirements to ensure new equipment is suitable and readily available to accept modifications.

Safety case engineering services

The operation of a civil nuclear facility is subject to regulation under the conditions of a licence or permit. The Licence Holder has a legal responsibility to demonstrate nuclear safety throughout the life-cycle of the facility (i.e. design, build, commissioning, operation, decommissioning etc). The accepted methodology for demonstrating nuclear safety is the development and continued maintenance of Safety Cases.

Rolls-Royce Safety Case Engineers are SQEP qualified and experienced in the preparation of Safety Cases at all stages in the life-cycle of a facility, including supporting new build licensing. Once a facility is operational, Rolls-Royce can provide the support to maintain a Safety Case to reflect ongoing operations and modifications; and can undertake Periodic Safety Case reviews.

In line with regulatory expectations, Rolls-Royce Engineers produce Safety Cases that are fit for purpose. Typically, this utilises a “claims-arguments evidence” approach, with emphasis on good engineering/deterministic assessments to demonstrate the safety of the plant and probabilistic safety assessments (PSA) to provide confirmation.

Regardless of which life-cycle stage it supports, a Safety Case remains the responsibility of the Licence Holder. Rolls-Royce recognises this and will seek to ensure the full involvement of the Licence Holder in the Safety Case engineering process.

Supporting capabilities:

  • Safety case authorship
  • Safety case management
  • HAZOP/HAZAN studies
  • ALARP/ALARA studies
  • Probabilistic safety assessment
  • Deterministic safety assessment
  • Fault tree analysis
  • Shielding
  • Transient analysis
  • Radiation shielding
  • Reactor physics
  • Internal hazard analysis
  • External hazard analysis
