## Summary

The United Kingdom Atomic Energy Authority has initiated a tender process for the service titled "STEP AC Loss Modelling". This procurement falls under the industry category of technical testing, analysis, and consultancy services, with a contract value of £45,000 GBP. The tender period ends on 17th May 2023, and the contract is set to commence on 22nd May 2023, with a completion deadline of 29th March 2024. The procurement method is an open procedure, and the service is deemed suitable for small and medium enterprises (SMEs).

This tender opportunity by the United Kingdom Atomic Energy Authority for AC loss modelling presents a lucrative business prospect for companies specializing in energy and related services or electric conductors for data and control purposes. Businesses interested in providing numerical calculation services and developing models for superconducting cables and coil sets within the Tokamak confinement system are well-suited to compete for this contract. The procurement process offers SMEs a chance to showcase their expertise in this niche technical field and collaborate with a prominent organisation in the energy sector.

## Notice

The service users of this contract will be the STEP Confinement Systems Workstream, and this procurement concerns the alternating current (AC) loss modelling for superconducting cables and coil sets in the Tokamak confinement system. The scope will include the numerical calculation of AC losses in the existing concept designs for the central solenoid (CS), toroidal field (TF) limbs and poloidal field (PF) coils and their electromagnetic interaction with plasma operation. Also, the impact of passive structures on AC losses needs to be assessed. In addition to technical reports, all the developed numerical models and algorithms are required to be disclosed to UKAEA
