Summary

Machine-generated summary

The United Kingdom Atomic Energy Authority (UKAEA) plans to refurbish three Super Grid Transformers (SGT1A, SGT1B, SGT1C) located north of the J5 Substation. These 400kV assets are approaching their fifth decade of service, and the project will form an Asset Life Extension Program during the 2026-2027 shutdown, addressing latent defects and obsolescence to secure a further 10 to 15 year life cycle. A site visit is scheduled for Wednesday 26th August at 9:00am, with further dates available on request. Suppliers must register interest via the EU Supply portal using the site visit request form.

Description

Provision of the refurbishment of three super grid transformers on the Culham Campus, as part of an Asset Life Extension Programme to the SGTs.
