Questions about OPAL

What is the OPAL research reactor and what does it stand for?

OPAL stands for Open Pool Australian Light-water reactor and is a research reactor that is designed to produce neutrons used in research and to produce radioisotopes.

What powers OPAL?

OPAL is fuelled by low-enriched uranium and capable of generating 20 MW (megawatts) of thermal power. However OPAL does not produce electricity and its sole function is to produce neutrons for research purposes and for products and services.

How safe is OPAL?

OPAL is very safe. Its design guarantees the protection of staff, the public and the environment from radiation hazards. Find out more about OPAL's safety.

What would happen if a plane flew into OPAL?

If a plane flew into OPAL there would be no damage to the reactor itself as it is protected against severe impacts by its design. OPAL is protected by a strong containment building that has thick concrete walls.

If there was an earthquake how would this affect OPAL?

OPAL is able to withstand an extreme earthquake and in this situation, OPAL would be safely shut down as a safety measure.
