Diagram showing basic design of a Mark 1 reactor like those of Fukushima Daiichi. When functioning properly, the reactor at center is filled with circulating water that bathes the contained fuel.

A first-of-its-kind nuclear reactor that will use a 3D-printed core, advanced materials, and integrated sensors and controls is on track for completion by 2023. Despite the COVID-19 pandemic, work ...

NANO Nuclear Energy Inc has assembled the first reactor core hardware of its ZEUS solid core battery reactor for initial non-nuclear testing. The fuel element being prepared for testing (Image: NANO ...

The Water Gas Shift Reactor Diagram result screen shows the major flows into and out of the water gas shift reactor (WGSR): IGCC: GET RESULTS: CO2 Capture, Transport & Storage: 1. Water Gas Shift ...

In a conventional reactor, a core’s behavior has to be monitored from the outside. But the new designs enabled by 3D printing will allow for embedded sensors that will provide data directly from ...

Salem 1 was taken off line on April 15 for what was expected to be a routine refueling outage. It was during a visual inspection of the reactor core that issues with a number of bolts were discovered.

Crews will replace 256 of the 764 nuclear fuel assemblies in the reactor core with new fuel. The biannual fuel outages allow all fuel to be replaced on a rotating schedule every six years.

The reactor is several stories high and about 15 feet across. At the bottom, fuel rods filled with radioactive uranium fill the core. The fuel roads are surrounded by more than a foot of concrete ...

For the first time ever, a reactor's core has been detected putting out more energy than was put into it — a small but consequential step in the race to unleash a near-limitless, zero-carbon ...

The micro-reactor, based on established nuclear technology, utilizes a compact and modular design capable of providing one to 10 megawatts of power. Each particle of uranium in its core is ...

Iran has ripped the core out of its Arak heavy water nuclear reactor so that it cannot produce weapons-grade plutonium, the Fars news agency reported, a crucial step that would make sanctions ...
