NineSigma, representing The Electrical Energy Analysis Institute (EPRI), invitations proposals from corporations and organizations that may advise, design, develop, and/or produce a robotic autonomous welding system on an autonomous (or remotely managed) cell robotic platform or develop a purpose-built cell robotic platform.

Over the previous many years, nuclear reactors have been probably the most vital energy sources worldwide. A lot of them are operational for years and require occasional restore.
At the moment, these repairing operations are carried out by an individual, who’s doubtlessly uncovered to radiation within the course of.
To considerably cut back the potential publicity to personnel throughout an outage and to allow repairing in areas which might be too harmful for human welders whereas the plant remains to be in operation, EPRI want to put the welding system on a cell platform, versus current fastened location programs with restricted process means.
The welding system ought to have the ability to function in excessive radiation environments to make repairs and perform generally carried out welding operations, together with weld overlays, repairing cracked elements and wall thickness corrosion, repairing and mitigating stress corrosion cracking, and repairing flaws and defects in current welds.
The welding required is for mitigation and restore, equivalent to pad welding to construct up materials over eroded areas on warmth exchangers and stress vessels, not for including new elements. The environments for many purposes shall be comparatively clear, although some might have water sprays.
The robotic’s dimension and welding clearances are finally as much as potential companions, because the consumer is considering studying what is feasible in inventive and modern options.
Submissions to this Problem have to be obtained by Might 15, 2023.
