Hydraulic tests completed at Turkey's Akkuyu 1

Akkuyu nuclear unit 1 in Turkey has completed hydraulic tests of its primary circuit systems, with pressure raised to 24.5 megapascals, about 1.5 times normal operating pressure, and water temperature reaching 135 degrees Celsius. The tests verified equipment status against design and international safety standards and put the automated process control system into operation. Cold functional tests began in June after dummy fuel was loaded. Hot functional tests follow next, at temperatures above 260 degrees Celsius, before the reactor loads actual fuel.

Where this fits

Akkuyu's progress toward grid connection demonstrates that large, firm nuclear capacity can be built and commissioned, a trajectory that takes years but ends with decade-spanning, weather-independent supply. Australia has banned nuclear generation by law, which means the country is foreclosed from the one dispatchable, low-emission power source with the smallest material footprint and longest asset life. Turkey's project, led by Russia's Rosatom, also underscores a second Energy Realism concern: that nuclear expertise and supply chains remain concentrated outside Australia's sovereignty, yet are being developed in real time while domestic law prevents domestic use.

What it means

Every year Akkuyu operates, it will displace gas firming and fossil generation from Turkey's grid without weather dependency or the land-use, battery-mining and Chinese supply-chain exposure that a renewables-only transition entails. Australia's ban forecloses the same option: the country will instead build a renewables-dominant grid dependent on gas peaking, imported battery materials and processed minerals from China, and a transmission overbuild to manage intermittency. The technical and political distance between a grid that can be built and one Australia has chosen is widening.

The bigger picture

Energy security is national security. This connects to the wider case at Unprepared: Australia's dependence on a strategic rival, and how ready it is for the world that is coming.
