The Challenge

ANSTO required detailed nuclear safety engineering services to undertake a radiological consequence risk assessment of its new liquid waste facility design to determine whether the radiological risks have been adequately mitigated through the current design prior to proceed with the next phase of the systems engineering lifecycle.

What We Did

Plan Safe resources engaged with the project engineering and safety team to identify the credible hazardous scenarios relevant to the operations foreseen in the new liquid waste facility, assess the radiological consequences for those scenarios, with relevant risk control measures and residual risk levels. Moreover, it was verified that adequate layers of protection were in place to meet the targeted risk level to confirm whether any safety instrumented function was required to achieve those safety objectives.

The Outcome

The risk assessment report produced enabled the client to determine the adequacy of the proposed liquid waste facility design based on the radiological risk levels and controls identified, and proceed with the next phase of the systems engineering lifecycle.
