Operational Safety Case Support to Engineering for External Hazards

Tender description

Nuclear Safety Case Support is required by RWM to support two key areas of engineering feasibility for a GDF related to External Hazards. Firstly, to support engineering studies on resilience to climate change, Safety Case input is required to define safety requirements for external hazards which could be exacerbated by climate change. This will provide the focus of the engineering studies on the feasibility of mitigation measures. Once mitigation measures to withstand the relevant external hazards have been developed, these can be incorporated into the relevant safety case databases to support the high-level claim that it is feasible that a GDF can tolerate design basis external hazards. This work will inform aspects of the GDF Site Evaluation process. Second, supporting engineering work on the feasibility of a coastal located GDF, Safety Case support is required to further define safety requirements for external hazards which could impact a GDF located on the coast. Further work will be required to understand the mitigation measures required for a coastal GDF to ensure defence against external hazards. This will ensure that any claims made are robustly backed up to demonstrate that it is both feasible and safe to operate a GDF in a coastal location. As part of this contract, a call-off allowance is to be included in order to provide additional safety case support on external hazards, the scope of which will be defined during the contract.
