The refurbishment concerned the reactor’s internal structural parts. Each of the eleven trays was divided into two halves. The packing list specifies 1,714 × 915 mm and 5 mm plate for these parts. The supply also included penetrations, ribs, rims and sealing rings.

The manufacturing brief specified grade 1.4466 and cutting, bending and welding operations. The delivery specification for the plate parts referenced EN 10028-7 and a type 3.1 inspection document.

Component set and delivery boundary

The final packing list dated July 2025 records 363 individual components in two packages with a net mass of 1,830 kg. The total includes all listed component types in the internal assembly. The listed components also include 66 lifting lugs, 88 blanking pieces and two groups of ribs.

The contract covered component supply for refurbishment of the internals. The contract boundary was component delivery for subsequent installation inside the existing reactor.

Outcome

A supplied set of structural components for refurbishment of 11 trays in an existing reactor.
