Material uncertainty over going concern
As part of the group structure rationalisation, the management intends to transfer the Company's assets and liabilities to BRB, a subsidiary within the General Nuclear International Limited Group, and is currently looking at practicalities of transferring the Company's operations to BRB, a process that may take some time to complete and is subject to eventual approval by the Board. Accordingly, the directors have prepared the financial statements on a basis other than going concern.

Significant events
- “The Company achieved UK regulatory approval for the UKHPR1000 nuclear reactor technology during the year 2022, deployed its technical staff to other group companies.”
- “This has triggered an impairment review as the UKHPR1000 nuclear reactor technology received UK regulatory approval in February 2022 and the delay in the Bradwell project will more than likely require fresh approval for the design changes when and if the project is approved by the UK Government. UKHPR1000 development costs are considered irrecoverable and have been fully impaired.”

Each % is (latest − prior) ÷ |prior| for the line item as filed. The comparison is only shown when the latest and prior accounts cover broadly equal-length periods — short or long stubs (typical around incorporation or a year-end change) are suppressed rather than misrepresented. Lines a company doesn't report are omitted. About these numbers
