Safety cases

Description

The framework agreement will consist of five lots: Lot 2: Shielding and Dosing; Lot 3: Safety Case — Thermal including Computation fluid Dynamics (CDF); Lot 4: Safety Case — Structural including finite Element Analysis (FEA) Impact; Lot 5: Safety Case — Technical Author; Lot 6: Safety Case — Peer Review. Lot 1 — Safety Case — Criticality was withdrawn from the framework. Along with radioactive waste management (RWM) and direct rail services (DRS) will be able to utilise and call-off the services to the framework agreement. Provision of scientific services to support the buyers design and licensing activities for packages containing radioactive fissile materials. The transport of radioactive materials (RAM) is governed by the International Atomic Energy Agency (IAEA) Regulations [1]. These regulations cover design, licensing and operation of RAM transport packages. The regulations define dose limits for RAM transport packages during normal conditions of transport (NCT) and modified limits following accident conditions of transport (ACT). Shielding assessments are required to calculate the dose emitted from packages carrying specific RAM contents. Provision of finite element analysis services to support the Buyers design and licensing activities for packages containing radioactive materials. Scope is to include thermal analysis of nuclear packages, containers and components thereof, thermal stress analysis of such equipment and the provision of specialised computational fluid dynamics (CFD) methodology to analyse and predict thermal currents and temperatures in complex shapes such as ships’ holds. Provision of FEA to support the buyers design and licensing team. The supplier will be required to compose clear and coherent technical information relating to aspects of radioactive material transport by determining the clearest and most logical way to present information and instructions for optimum reader understanding. The supplier will be required to provide suitably qualified and experienced personnel to provide a documented, critical review of the buyers prepared safety case or any other documents. Such review will include an in-depth and independent appraisal of assumptions, calculations, methodology, and acceptance criteria used in the buyers safety case. To highlight conclusions and confirm adequacy of the original package of work.
