- Unqualified (clean)
- Going concern
- Affirmed
“Based on the detailed cash flow forecasts prepared by management, which included any reasonably possible change in key assumptions on which the cash flow forecasts themselves were based, the directors continue to believe that there is a reasonable expectation that the NNL Group has adequate resources to continue to adopt the going concern basis in preparing these financial statements.”

Significant events
- “As we entered the financial year, NNL was recovering from the impact of a legacy issue with the radiological shielding of manipulator ports within our Active Handling Facility (AHF). The return to service plan for AHF has been closely managed and held throughout the year, seeing our facility coming back online in a phased programme to support business delivery. Whilst we continue to achieve our targets relating to safety and security we did encounter both a significant event and two near misses in the financial year.”
- “Immediately prior to the year end we were notified that Sellafield Limited have taken the decision to bring the Replacement Analytical Project (RAP) to a strategic pause. This decision will have implications for our people, finances and facilities and we are working closely with Sellafield to manage these implications.”

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
