HPC News Update – July 2022

Milestone set in concrete

Team Concrete, comprising Bylor and its partners, has reached a significant landmark, successfully pouring a staggering 1,000,000m3 of concrete. The landmark batch was poured by the same team who poured the first concrete produced to nuclear quality standard in March 2017. The first official nuclear quality concrete was poured during work on the W1 Galleries Base in Unit 1. Since then, all the required mixes – whether for inner containment, self-compacting or heavyweight applications – have been validated and supplied across the project on a regular basis. Maintaining that quality, consistency and volume has been a real team effort, with Hanson supplying the material itself, D&C Engineering providing control through its batching plants and Bylor team members delivering and pouring the concrete into position all over the Site using mobile and static machinery.

Reactor safety barrier taking shape

The sixth layer of inner containment on Unit 1, the 1.3m-thick circular concrete structure that forms part of the reactor’s safety barrier, is now in place following a 30-hourpour in the reactor building. In total, layer six required 720m3 of concrete and about 135 tonnes of rebar.
