Loading of nuclear fuel starting on 21 August 2010 signalled the activation of the 1,000 megawatt plant, with 80 tonnes of fuel transferred to the reactor building and into the core. It will take another 2 to 3 months for the reactor to ramp up to 500 megawatts and start sending electricity to Iranian towns. The International Atomic Energy Agency (IAEA) expects the plant to be connected to the civil grid in December 2010.

The Bushehr nuclear power plant is one of 60 sites tracked by SPOTMonitoring.
The SPOTMonitoring team optimizes tasking of a constellation of high- and very-high-resolution optical and radar satellites to guarantee image acquisition as required by service subscribers. Its domain experts then analyse imagery, produce illustrated reports, post data on a secure site and send out e-mail alerts to subscribers.

As soon as the loading of fuel into the reactor core was announced, subscribers asked to switch from monthly monitoring to daily image acquisition, with three change-detection alert levels:

• Red for new activity
• Orange for regular activity
• Green for no activity

Subscriber's interest initially focused on the presence of vehicles at the site, and on any traces of smoke or new construction work. From 21 August 2010, attention turned to movements of the portal crane alongside the reactor building.
