The pace was picked up on the second ring of the reactor building in Reactor One – in fact, the time taken per metre of weld was 36% quicker than the first ring.
This saving all adds up when you consider that the prefabricated steel ring has a diameter of 47 metres, is more than 17 metres high and requires 934 metres of welds!
Over on Reactor Two, a major concrete pour for the foundations of the reactor building was completed three months quicker than the same one for Reactor One. Valuable lessons learned from the previous pour helped the team achieve the milestone quicker this time. In total, 2,240m3 of concrete was poured during a 36-hour continuous pour.
